In this article, we will look into the 25 largest economies in the world by 2100. If you want to skip our detailed analysis, you can go directly to 5 Largest Economies in the World by 2100.

Global Economic Prospects

The global economy presents sluggish near-term progress, with the ongoing geopolitical crises and enduring effects of the pandemic. Climate change is another major factor, leading to resource and economic losses due to significant changes in its trajectory. However, the future predictions paint a rather hopeful picture for the global economy. In 2024, the global economy is expected to grow at 3.1% and is expected to grow at 3.2% in 2025, according to the latest economic outlook by the IMF. The recent forecasts are slightly higher than the previously estimated GDP growth in the October 2023 economic outlook. This can be attributed to the strong performance depicted by several countries such as the United States, and policy interventions such as fiscal support in China. The forecast, however, is still below the historical growth average of 3.8%. Inflation is expected to decrease faster than expected and reach 5.8% in 2024, and 4.4% in 2025. This downtrend in inflation, coupled with steady growth, minimizes the risk of a severe economic downturn. The declining inflation presents an opportunity for countries to shift their focus toward fiscal consolidation and targeted policies to improve productivity and long-term growth. Despite the resilient growth projections, several challenges can affect this trajectory, such as a declining population growth rate. The projected population represents a substantial slowdown, compared to previous decades. This shift is expected to impact economic growth, along with factors such as weakened productivity, as predicted by economists.

On the contrary, the long-term outlook paints a rather stable picture, especially for Asian economies. According to the forecast by Fathom Consulting, Asian economies such as China and India are expected to lead the global economy with the highest GDP share. The report forecasts China to have a share of 22.68% and reach $101 trillion by 2100. Moreover, Asian countries such as Indonesia, Japan, and the Philippines are some other nations, that are expected to emerge as global leaders, in terms of GDP. These countries are also ranked among the largest economies in the world by 2050.

Role of Companies in Driving Economy

The long-term economic landscape presents the potential supremacy of Asian nations such as China and India, along with the established influence of the US. While these macroeconomic trends provide us with a broader picture of the economy, it is pertinent to acknowledge the crucial role that major corporations play in these countries and around the world. Among other factors, businesses across major economic regions are a driver of growth globally. Leading companies such as Tencent Holdings Limited (OTC:TCEHY), Alphabet Inc. (NASDAQ:GOOG), and Reliance Industries Ltd (NSE:RELIANCE) are some of the most valuable companies from the biggest countries in the world.

Tencent Holdings Limited (OTC:TCEHY) is a technology leader in China, operating across Asia and the Pacific, North America, and Europe. The company’s stock has surged nearly 8% over the past month, as of February 21. The company has a diverse portfolio of brands including Tencent Pictures, WeiShi, QQ Wallet, Q Zone, QQ Browser, Weixin/WeChat, and QQMail. As of February 21, Tencent Holdings Limited (OTC:TCEHY) has a market cap of $349.4 billion.

Alphabet Inc. (NASDAQ:GOOG) is an established leader in the global market, boasting a market cap of $1.78 trillion, as of February 21. The company reported its earnings for the fiscal fourth quarter of 2023 on January 30. It reported earnings per share of $1.64, beating the estimates by $0.04. Alphabet Inc.’s (NASDAQ:GOOG) revenue for the quarter amounted to $86.31 billion and outperformed estimates by $1.03 billion, with a year-over-year increase of over 13%.

Reliance Industries Ltd (NSE:RELIANCE) is one of the most valuable Indian companies, boasting a market cap of $240 billion, as of February 21. The company is home to 170 in-store brands and has millions of customers all over the country. On January 19, Reliance Industries Ltd (NSE:RELIANCE) announced its results for the fiscal third quarter of 2023. The company reported gross revenue of $29.8 billion, with a 3.2% year-over-year increase. Reliance Industries Ltd (NSE:RELIANCE) also witnessed a growth of 11.4% and 22.8% in its Jio Platforms division and Reliance Retail Ventures Limited.

Now, let’s have a look at the 25 largest economies in the world by 2100.

25 Largest Economies in the World by 2100

Methodology

To compile our list of the 25 largest economies in the world by 2100, we consulted ‘Economics in the Year 2100‘ by Fathom. It provides data for the estimated percentage share of countries in the global GDP in 2100. It also reports the GDP PPP of the top ten economies. We utilized the data for the GDP PPP value of the top countries and percentage share to calculate the total global GDP value in 2100. Our calculation yielded that the global GDP is projected to be approximately $449 trillion by 2100. After calculating the global GDP in US dollars, we estimated the GDP PPP for the countries to provide insight into their projected values. Our list ranks the 25 largest economies in the world by 2100 in ascending order of their GDP share. We used the population projections for 2100, by the UN, as a tie-breaker for the countries with the same percent contribution to the global economy in 2100.

By the way, Insider Monkey is an investing website that tracks the movements of corporate insiders and hedge funds. By using a consensus approach, we identify the best stock picks of more than 900 hedge funds investing in US stocks. The top 10 consensus stock picks of hedge funds outperformed the S&P 500 Index by more than 140 percentage points over the last 10 years (see the details here). Whether you are a beginner investor or a professional one looking for the best stocks to buy, you can benefit from the wisdom of hedge funds and corporate insiders.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

Published on May 16, 2026 at by Inan Dogan, PhD

Dr. Ian Dogan

Co-Founder and Research Director at Insider Monkey

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

175 Teslas
107 Amazons
140 Metas
84 Googles
65 Microsofts
And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…

This prediction might not be bold at all:

A few years from now, you’ll wish you’d owned this stock.

Wall Street calls this $3 stock a “Melting Ice Cube.” They said the same thing about BTI before it returned 90%.

My name is Inan Dogan. I’m the co-founder and Research Director of Insider Monkey. I have an important message for you today.

Since March 2017, my stock picks have returned 16.5% annually. Today, I’ve found an opportunity even bigger than my British American Tobacco call.

Two years ago, Wall Street wrote off British American Tobacco (BTI) as a “melting ice cube.” The stock had crashed 40% from its peak, and consensus said the business was dying.

We looked under the cover and realized they were wrong.

We alerted our subscribers, and BTI returned 90% in just 16 months.

Now if you had invested just $10,000 in BTI in June 2024, you’d be sitting on $19,000 in October 2025.

Today, we have identified a nearly identical pattern in a digital-first giant trading at $3.

While the market panics over a surface-level revenue decline, our PhD-led research shows management has actually surgically cut $100 million in waste to focus on high-margin growth.

This pattern is a hallmark of our 16.5% annual return track record. The current opportunity offers a 400% upside potential—dwarfing even our 90% BTI return.

Get the ticker for our new “Underdog” pick and the full BTI case study for just 99 cents.
