Saudi Arabia sits on roughly 267 billion barrels of proven crude oil reserves. For nearly a century, that oil has financed everything: roads, hospitals, palaces, the military, and the government subsidies that kept fuel prices cheaper than bottled water. It underwrote a social contract that kept an absolute monarchy stable in a region where governments collapsed like dominoes. Yet the man who actually runs the country, a crown prince still in his thirties, looked at all of it and concluded that it was not enough.

Saudi Arabia, he decided, had to become something entirely different. The attempt to remake the kingdom is one of the most consequential economic experiments of the twenty-first century, because Saudi Arabia did not merely build its wealth on oil. It built its identity, its foreign policy, its alliances, its leverage over the global economy, its relationship with the United States, and its standing in the Islamic world on that single commodity. Reforming the economy means re-forging the foundations of the state itself.

To understand why the kingdom is attempting this transformation, and whether it can succeed, the story must begin in the 1930s, when the Arabian Peninsula was among the poorest and most isolated places on Earth. The Kingdom of Saudi Arabia had only been unified in 1932 by Abdulaziz ibn Abdulrahman Al Saud, a warrior king who had spent decades conquering rival tribes and territories. Unifying the land, however, was not the same as feeding its people. The new state had almost no natural resources.

Its economy depended on the pilgrimage to Mecca and Medina, modest trade, and subsistence farming and herding. The Great Depression of the 1930s sharply reduced the number of pilgrims, and the young kingdom faced severe financial distress. So when American geologists working for Standard Oil of California arrived in the Eastern Province in 1933, they were not greeted with much enthusiasm. King Abdulaziz signed a concession agreement on May 29 of that year, granting the Americans the right to explore for oil in exchange for modest payments and royalties.

A subsidiary, California Arabian Standard Oil Company, was established to manage operations on the ground. Expectations were low. The geologists set up camp near the town of Dhahran, enduring extreme heat, sandstorms, and isolation in an environment with no comforts or services. They drilled one well after another without success.

Money was running out, patience was wearing thin, and many in the company were ready to withdraw entirely. Then on March 3, 1938, everything changed. Commercial quantities of crude oil were discovered in a well known as Dammam Well Number 7, which the drillers had nicknamed the Well of Prosperity. It was not a modest flow but a massive one, indicating something enormous beneath the Saudi desert.

Within months it became clear that Saudi Arabia possessed one of the largest oil reserves ever discovered in human history. The Ghawar field, found shortly afterward, proved to be the largest conventional onshore oil field in the world. It would produce more oil on its own than most nations have ever produced in total. Still, the discovery did not transform the kingdom overnight.

World War II slowed development, and it took years before the infrastructure needed to export oil in large quantities was ready. By the late 1940s and early 1950s, however, the money began to flow. Between 1939 and 1953, Saudi oil revenues jumped from about 7 million dollars to more than 200 million dollars. That was only the beginning.

The kingdom became entirely dependent on oil revenues, and the entire structure of state, economy, and society was built around this single commodity. To manage the new wealth, the Arabian American Oil Company, known as Aramco, became the most important institution in the country after the monarchy itself. Originally controlled by a consortium of American oil companies, including what would later become Chevron, Exxon, Texaco, and Mobil, Aramco operated the oil fields, built infrastructure, and managed the energy sector on behalf of the Saudi government. The relationship was symbiotic but unequal.

The Americans brought technology and expertise, while the Saudis provided land and crude oil. For decades, profits were split in a way that heavily favored the foreign companies. That situation began to change in the 1970s, and what happened next made Saudi Arabia one of the most powerful nations on Earth almost overnight. In October 1973, the Yom Kippur War broke out between Israel and an Arab coalition led by Egypt and Syria.

When the United States and several Western nations provided military support to Israel, King Faisal bin Abdulaziz Al Saud made a decision that reshaped the global economy. He led the Arab members of the Organization of Petroleum Exporting Countries in imposing an oil embargo on the United States, Britain, Canada, Japan, and the Netherlands. Oil exports to these nations were cut off entirely. The impact was immediate and severe.

Oil prices nearly quadrupled almost overnight, jumping from about three dollars a barrel to nearly twelve dollars. Gas stations across America ran dry, and lines stretched for miles. Economies that had flourished on cheap energy fell into simultaneous recession and inflation, a phenomenon economists labeled stagflation. One historian described the embargo as perhaps the largest peaceful transfer of wealth from industrial to developing nations in human history.

For Saudi Arabia, the embargo was a dramatic turning point. Oil revenues jumped from 8. 5 billion dollars in 1973 to 35 billion dollars in 1974. Over the following decade, as prices continued climbing through the Iranian Revolution and the second oil shock of 1979, the kingdom accumulated enormous wealth, almost impossible to absorb for a country of its size and population.

This was the era of the great Saudi oil boom, a transformation with no modern parallel. A country that had been mostly pastoral and agricultural suddenly found itself awash in more money than it could spend. Massive infrastructure projects were launched in every corner of the kingdom. New cities were built from nothing.

Riyadh, once a modest desert town surrounded by mud walls, became a sprawling modern capital. Jeddah became a global coastal city. The Eastern Province, where the oil was located, became an industrial hub. Highways, airports, universities, hospitals, desalination plants, and communications networks were built at extraordinary speed, all funded by oil revenues.

The government provided free education and healthcare, heavily subsidized utilities, and guaranteed public-sector employment for Saudi citizens. There was no income tax, and none was needed. Oil paid for everything. During this same period, the Saudi government completed a process that had been underway for years: the full nationalization of Aramco.

In 1973 the kingdom acquired a 25 percent stake. By 1980 it had purchased the remaining shares and owned the company outright. Renamed Saudi Aramco, it became the crown jewel of the Saudi economy, the most valuable company on Earth, responsible for producing nearly twelve million barrels of crude oil per day, with reserves sufficient to sustain production for decades. But there was a critical flaw in building an entire country on a single commodity.

The system worked brilliantly when prices were high, but it became an existential crisis when they collapsed. In the mid-1980s, global oil prices crashed. After years of high prices, other countries increased production, consumers began conserving energy, and OPECs influence weakened. The price of oil fell from more than thirty dollars a barrel to below ten dollars.

Saudi revenues were severely hit, forcing the government to cut spending sharply and shelve ambitious projects. The era of seemingly limitless wealth ended suddenly and painfully. This was the first real warning. The Saudi economy had no other significant source of income.

The private sector was small and heavily dependent on government contracts funded by oil revenues. Manufacturing was extremely limited, tourism was nearly nonexistent, and the financial sector was modest. When the oil price dropped, everything contracted. Prices eventually recovered, but the fundamental weakness remained.

Over the following decades, the cycle continued. Oil prices rose, spending surged. Oil prices fell, austerity followed. Beneath the surface, a demographic time bomb was ticking.

The Saudi population was young and growing rapidly. By the early 2010s, nearly 70 percent of the population was under thirty. The traditional social contract, in which the government provided comfortable public-sector jobs and generous subsidies in exchange for political loyalty, had become unsustainable. There simply were not enough government jobs to absorb the flow of young Saudis entering the labor market every year.

Youth unemployment rose, and with it the potential for social unrest. Then there was the long-term existential threat that no one in Riyadh could ignore. The world was beginning to move away from fossil fuels. Electric vehicles were no longer a curiosity.

Renewable energy became cheaper every year. Climate agreements were signed. Major economies set net-zero targets. The question was not whether the oil age would end, but when, and whether Saudi Arabia would be ready when it did.

This was the background when one of the most dramatic political and economic transformations of modern history began to unfold. In January 2015, King Abdullah bin Abdulaziz died at the age of 79. His successor, King Salman bin Abdulaziz, was in declining health. The most important thing he did was not what he accomplished himself, but what he entrusted to his son.

Within weeks of taking the throne, King Salman appointed his 29-year-old son Mohammed bin Salman as defense minister and head of a newly created Council for Economic and Development Affairs. It was an unprecedented concentration of power for someone so young and relatively unknown within the royal family. Mohammed bin Salman, known by his initials MBS, was not a typical Saudi prince. He had not been groomed for decades in the traditional succession hierarchy.

He had not served as governor of a major province or held senior ministerial posts. By all accounts, he was ambitious, impatient, and convinced that the old way of doing things was leading Saudi Arabia toward the abyss. He moved with a speed that stunned the Saudi establishment and the world. In April 2016, the crown prince unveiled Vision 2030.

It was not merely a policy document or a set of economic targets. It was a blueprint for rebuilding the entire Saudi state and society. The core idea was simple: Saudi Arabia was addicted to oil, and this addiction would inevitably destroy the country if it was not broken. The solution was to radically diversify the economy so that oil became part of a broader, more resilient economic base.

The ambitions were enormous. Vision 2030 aimed to increase the share of non-oil revenues from about 10 percent of total government revenue to a much higher level. It set targets for increasing the private sectors contribution to GDP from 40 percent to 65 percent. It aimed to raise tourism visitors from fewer than 20 million a year to more than 100 million.

It sought to triple non-oil exports and create hundreds of thousands of new private-sector jobs for Saudi citizens. It proposed transforming the Public Investment Fund, the kingdoms sovereign wealth fund, into one of the largest and most active investment funds in the world. Announcing a vision was easy. Implementing it inside a conservative, bureaucratic, oil-dependent country like Saudi Arabia was something else entirely, and the crown prince knew it.

That is why the implementation of Vision 2030 was accompanied by a forceful consolidation of political power that effectively removed every potential obstacle in his path. In June 2017, King Salman stripped his nephew Mohammed bin Nayef of the title of crown prince and granted it to Mohammed bin Salman. The message was clear: MBS was now the de facto ruler of Saudi Arabia, and anyone standing in the way of his agenda would be marginalized. A few months later, in November 2017, he launched what he called an anti-corruption campaign.

In a single dramatic night, hundreds of the countrys most powerful businessmen, princes, and former officials were detained at the Ritz-Carlton hotel in Riyadh. Some remained in custody for months, and many were forced to hand over billions of dollars in assets in exchange for their release. The social reforms accompanying the economic plan were equally radical for a country as conservative as Saudi Arabia. Women were permitted to drive for the first time in 2018.

Cinemas were reopened after a 35-year ban. Mixed-gender entertainment events were allowed. The religious police, once enormously influential in enforcing strict social rules, saw their authority sharply reduced. Concerts, comedy shows, and international sporting events began flooding into the kingdom.

Saudi Arabia was reshaping its image, not just economically but culturally, as a modern, open, forward-looking nation. The most prominent project of Vision 2030, however, the one meant to embody the kingdoms leap into the future more than anything else, was NEOM. Announced in 2017, it was described as a 500-billion-dollar mega-city built from scratch in the desert of northwestern Saudi Arabia on the Red Sea coast. It was to be powered entirely by renewable energy.

It would have no cars, no streets in the traditional sense, and would use artificial intelligence and robotics to manage everything from waste disposal to healthcare. At the center of NEOM was The Line, a stunning concept of a linear city stretching 170 kilometers across the desert, enclosed by 500-meter-high mirrored glass walls, housing up to nine million people in a carbon-emission-free structure. The promotional videos were cinematic, and the ambition was seductive. For a moment, NEOM became the most talked-about construction project in the world.

But ambition and reality are different things, and the reality of NEOM proved far more complicated than the glossy images suggested. By 2025, the problems were impossible to ignore. The Public Investment Fund had formally halted construction on The Line in September 2025 pending a strategic review. Only about 2.

4 kilometers of foundations had been completed out of the planned 170, roughly 1. 4 percent of the total length. Population targets had been repeatedly reduced from nine million to 1. 5 million to 300,000 and then lower.

The mirrored glass facades existed only in computer designs. NEOM job listings had fallen by about 75 percent by 2025, and more than a thousand employees had been relocated from the remote construction site to offices in Riyadh. The projects long-serving chief executive resigned in November 2024. Internal audits reportedly revealed evidence of financial manipulation.

By mid-2026, reports indicated Saudi Arabia had canceled the railway in its original form, with the Public Investment Fund spending billions more to settle existing contracts. The cost of the effort was estimated at more than 50 billion dollars, with little to show in terms of a livable city. Critics were quick to declare NEOM a spectacular failure and proof that Vision 2030 was nothing more than a vanity project. But this interpretation, however understandable, misses the broader picture.

While the most ambitious elements of NEOM were being quietly scaled back, many other parts of Vision 2030 were producing concrete results. This is what makes the story important, because the Saudi transformation is not a simple narrative of success or failure. It is a more complex and nuanced process. According to the 2025 annual Vision 2030 report, non-oil activities now account for roughly 55 to 56 percent of GDP, up from about 45 percent when the vision was launched in 2016.

Non-oil GDP has grown consistently faster than overall GDP, expanding by nearly 5 percent in 2025 alone. The Saudi economy passed the 1. 3 trillion dollar mark in 2025, a nominal increase of about 80 percent since the plan was launched. Non-oil exports reached 624 billion Saudi riyals, about 166 billion dollars, up 15 percent from the previous year.

The private sector now contributes 51 percent of GDP. Female labor force participation, below 20 percent when the crown prince took power, has risen above 30 percent. Tourist numbers have surged, with the kingdom attracting more than 100 million visitors a year, beating its original 2030 target years ahead of schedule. The Public Investment Fund has grown its assets under management from about 192 billion dollars in 2016 to more than 900 billion dollars, with some estimates suggesting assets exceed 1.

2 trillion dollars when recent Aramco share transfers are counted, making it one of the largest sovereign wealth funds in the world. The fund has become one of the boldest investors in global markets. It acquired an 80 percent majority stake in Newcastle United Football Club in the English Premier League. It invested more than 3 billion dollars in player acquisitions and infrastructure development for four major Saudi football clubs.

It backed LIV Golf, which disrupted the entire professional golf industry and ultimately forced a partnership agreement with the PGA Tour. It hosted Formula E races, world championship boxing matches, WTA tennis finals, and the first Esports World Cup in Riyadh. In gaming, Savvy Games, backed by the Public Investment Fund, invested more than 37 billion dollars to become one of the largest gaming and esports companies in the world. In September 2025, the fund participated in the 55-billion-dollar acquisition of Electronic Arts, the largest leveraged buyout in history.

In aviation, Saudi Arabia launched Riyadh Air, an entirely new national airline aiming to turn Riyadh into a global transit hub competing with Dubai and Doha. In technology, the fund has invested in companies ranging from Lucid Motors in electric vehicles to ride-hailing apps, artificial intelligence projects, and data center infrastructure. With NEOM mega-projects scaled back, significant portions of the projects industrial zone, known as Oxagon, were redirected toward hyperscale data center complexes through a 5-billion-dollar partnership with DataVolt. There is also the energy dimension of this diversification.

Instead of abandoning oil, Saudi Arabia is seeking to maximize its remaining value while preparing for the future energy landscape. NEOM Green Hydrogen Company, a joint venture between NEOM, ACWA Power, and Air Products, reached 80 percent construction completion by early 2025. The 8. 4-billion-dollar facility is designed to produce up to 600 tons of carbon-free hydrogen daily, making it one of the largest green hydrogen plants in the world.

Saudi Arabia is betting that hydrogen will be a fuel of the future and positioning itself as a major producer. At the same time, Saudi Aramco remains a massive source of profit, the most profitable company in any sector globally. When Aramco held its initial public offering in December 2019, listing nearly 1. 5 percent of its shares on the Saudi stock exchange, it briefly became the most valuable company in the world, surpassing Apple.

The IPO raised about 25. 6 billion dollars, then the largest IPO in history. Yet the fundamental tension at the heart of the Saudi strategy is that Saudi Arabia needs oil revenues to finance diversification away from oil. What the kingdom is trying to eliminate is the very thing paying for its elimination.

When oil prices fall, as they did in mid-2025 when prices dropped below 80 dollars a barrel, the financial calculations quickly become unstable. The fiscal break-even oil price, the price the government needs to balance its budget, has risen as spending on mega-projects has increased, with estimates placing it above 90 dollars a barrel. When actual prices fall below that level, the government runs budget deficits, drains reserves, or cuts spending on the projects meant to build the post-oil economy. It is a circular trap and the greatest threat to the entire Vision 2030 project.

There are other risks as well. The human rights dimension cannot be ignored in any objective assessment. The crown princes consolidation of power was accompanied by a severe crackdown on dissent. Activists, journalists, women’s rights advocates, and even members of the royal family have been arrested, imprisoned, or worse.

The murder of journalist Jamal Khashoggi inside the Saudi consulate in Istanbul in October 2018, which US intelligence assessed the crown prince had approved, shocked the international community and severely damaged Saudi Arabia’s reputation at a critical moment when it was seeking foreign investment and tourism. The kingdom’s involvement in the devastating war in Yemen, launched by the crown prince in 2015 when he was defense minister, caused a humanitarian catastrophe and complicated the country’s international standing. The authoritarian character of the regime remains a persistent concern for foreign investors, international institutions, and potential partners. There is also the challenge of implementation.

Vision 2030 is not a single project. It is hundreds of projects, thousands of initiatives, and millions of interlocking elements that must come together coherently. The NEOM experience shows what happens when ambition exceeds planning and engineering reality. Not every part of the vision will succeed.

Some projects will be scaled back, others will fail entirely. The question is whether the overall trajectory is moving in the right direction, and whether the investments will yield enough to create a genuinely diversified economy before the era of oil revenues ends. At this point the evidence is mixed but cautiously leaning positive. Non-oil economic growth is real and measurable.

Tourism is thriving. Entertainment and sports sectors have created genuine new economic activity and transformed the country’s cultural climate. Women’s labor force participation has expanded in ways unimaginable a decade ago. The financial sector is growing.

Technology is attracting investment. The sheer scale of the Public Investment Funds global portfolio means Saudi Arabia now has income sources entirely independent of oil prices. But declaring victory would be naive. Despite the growth of the non-oil economy, it remains heavily dependent on government spending and Public Investment Fund investments, which are in turn funded by oil revenues.

The private sector is expanding, but many new jobs and companies are directly or indirectly tied to massive government projects. Genuine organic private-sector growth, growth that thrives on its own without state direction, is still in its early stages. The cultural transformation, however impressive on the surface, is being implemented from the top down in a society with deeply rooted conservative traditions. Questions remain about how sustainable these changes are, or whether they could be reversed under different political circumstances.

The mining sector deserves mention as well. Saudi Arabia has discovered massive mineral deposits, including phosphate, gold, copper, zinc, and rare earth elements. The government has created a completely new regulatory framework for mining, established a dedicated ministry, launched geological surveys, and begun granting exploration licenses to attract global mining companies. The goal is to turn mining into a third pillar of the economy alongside oil and the new diversified sectors, potentially generating tens of billions of dollars in annual revenues from resources that have lain beneath the desert for thousands of years.

Regional competition cannot be forgotten. Saudi Arabia is not the only Gulf state seeking to diversify its economy away from oil. The United Arab Emirates, and Dubai in particular, has been far ahead for decades. Dubai began its diversification efforts long ago and established itself as a global hub for finance, tourism, logistics, and technology.

Qatar has invested its natural gas wealth in world-class infrastructure and hosted the 2022 World Cup. Bahrain, Oman, and Kuwait have their own diversification strategies, albeit on a smaller scale. Saudi Arabia is the largest and richest of these states, but it started late and is trying to achieve more in a shorter period. What distinguishes the Saudi experiment, and makes it more worthy of close attention than any other economic experiment on the planet today, is the sheer scale of the bet.

This is a country with a GDP of more than a trillion dollars, a population of more than 32 million, and a sovereign wealth fund with assets exceeding 900 billion dollars, all being redirected toward a radically different economic model within a single generation. There is no historical precedent. No country of this size, with this level of wealth, and this degree of dependence on a single commodity, has ever attempted such an ambitious transformation with such speed. It is also worth being clear about what is at stake if this transformation fails.

Saudi Arabia is not just any country. It is the custodian of the two holiest cities in Islam. It is an influential producer in global oil markets, meaning its decisions about how much oil to pump directly affect fuel prices in every country on Earth. It is a crucial security partner for the United States and a major buyer of weapons.

It is a key player in the geopolitics of the Middle East. Destabilizing Saudi Arabia, draining its resources, facing mass unemployment among its youth, or experiencing political upheaval would have repercussions on the global economy that would make the 2008 financial crisis seem minor by comparison. These are the calculations driving the crown prince. This is why his ambition is so aggressive and his pace so rapid.

He is not diversifying the Saudi economy because it is fashionable or on the advice of consultants. He sees the end of the oil era approaching and knows the consequences of Saudi Arabia being unprepared would be catastrophic. Oil will not run out tomorrow. Saudi Arabia has enough reserves to keep pumping for decades.

But demand may change. In a world moving toward electricity and renewables, with growing hostility to carbon emissions, the signs are clear. With each passing year, the urgency increases. There is a paradox here worth reflecting on.

Saudi Arabia, the country that arguably benefited more than any other from the fossil fuel era, is now working hard to escape it. The wealth earned from oil is being deployed to build something that does not need it. It is as if the kingdom looked at its own history, saw how oil transformed it from a collection of nomadic tribes into a global power, and decided it needs a similarly radical transformation before the source of that power fades. The success of this transformation will depend on factors that are difficult to predict with any precision.

It will depend on oil prices, global economic conditions, the speed of the energy transition, the kingdoms ability to attract and retain the foreign talent and investment it needs, how deep the social reforms go in creating a genuine culture of innovation and entrepreneurship, and how well a political system based on absolute monarchy adapts when things do not go according to plan. What can be said with confidence is that the attempt itself is remarkable. Whether admired or condemned, the Saudi gamble is one of the defining economic stories of our era. It is a story of power and money, of oil and sand, of a young prince with nearly unlimited resources and a very short window of time to reshape an entire nation before the world moves on without it.

Consider what has actually happened in less than a decade. A country where women were not allowed to drive now has women in senior corporate positions and founding businesses. A country where cinemas were banned now hosts international film festivals and esports championships. A country whose sovereign wealth fund passively held treasury bonds now owns stakes in everything from English football clubs to American video game companies to green hydrogen plants.

A country where 90 percent of government revenues came from oil has reduced that dependence to below 50 percent. None of this is a small achievement. But on the other hand, a country that announced the largest construction project in history quietly froze it after spending 50 billion dollars. A country that promised transparency and openness imprisoned activists and journalists.

A country that needs foreign investment has alienated potential partners over its human rights record. A country seeking to build a knowledge economy still struggles with an education system designed for a different era. These contradictions are not temporary. They are structural, and how they are resolved will determine the outcome.

The question that hangs over everything remains unanswered: can a country built entirely on oil survive without it? The next decade will provide the answer.
