In 2006 the combined market capitalisation of every stock exchange on earth was approximately $50 trillion. In 2026 that number is $130 trillion. In twenty years, humanity created more financial wealth than existed in all of prior recorded history combined. This letter asks three questions: where did it come from, who captured it, and what does the map of that capture tell us about the next twenty years.

Put the number in perspective first, because it is easy to read past it without registering what it actually means. In 2006, every company listed on every stock exchange in every country on earth was collectively worth approximately $50 trillion. That $50 trillion was itself the product of centuries of industrialisation, colonisation, capital accumulation, and the greatest peacetime economic expansion in recorded history — the post-war boom, the technology revolution, the globalisation wave of the 1990s. All of it. Every company. Every exchange. Fifty trillion dollars.
By mid-2026, that number is $130 trillion. In the twenty years between 2006 and 2026, humanity created $80 trillion in additional market value — more than existed in the entire world at the start of the period. This is not a gradual compounding story. It is a multiplication event, concentrated in specific technologies, specific geographies, and specific moments: the recovery from the 2008 financial crisis that created the conditions for the longest bull market in American history, the smartphone revolution that created trillion-dollar companies from nothing, and the AI investment surge of 2023-2026 that added more market value in three years than most countries' entire economies.
Three forces drove it simultaneously and each deserves naming separately. First, financialisation — the shift in corporate strategy from retained earnings and reinvestment to shareholder returns, buybacks, and market capitalisation maximisation, which structurally inflated price-to-earnings ratios across every developed market. Second, the technology premium — the market's discovery that software companies with near-zero marginal costs could generate returns on capital that no prior business model had achieved, creating a new category of corporate value that did not exist in 2006 and which now comprises the majority of the US market's total capitalisation. Third, monetary conditions — the post-2008 era of near-zero interest rates that made equities the only serious asset class for yield-seeking capital, driving inflows that would have been unimaginable to a 2006 fund manager.
The geographic story of this twenty-year period is at least as significant as the aggregate number — and it is the story that most Western financial media has consistently underweighted, because the shift happened gradually enough that no single year felt like the decisive moment. In 2006, the top ten stock markets by total capitalisation were dominated by the United States, Western Europe, and Japan. Asia's representation was essentially Japan and, at the margins, perhaps one other. China was growing at double-digit rates but its domestic equity markets were small, illiquid, and largely inaccessible to foreign capital. India was an emerging market story that analysts discussed in the future tense. Taiwan and South Korea were technology producers, not financial powerhouses.
By 2026, six of the world's ten largest stock markets by capitalisation are Asian. China has grown from a footnote to a $14-17 trillion market — a 25-fold increase over twenty years that represents the fastest wealth creation by a single country in capital markets history. India has crossed $5 trillion, making it a genuine top-five market and the story every asset allocator is writing about for the next decade. Taiwan's semiconductor concentration and South Korea's technology and AI exposure have driven both markets into the top ten. Japan has maintained its position. The result: the geographic centre of global capital markets has moved east in the most significant rebalancing since the emergence of the United States as the dominant financial power in the early twentieth century.
The European story deserves particular attention because it is the dog that didn't bark. The United Kingdom's market capitalisation has moved from a significant global hub position in 2006 to approximately $3.9-4.0 trillion in 2026 — roughly flat in absolute dollar terms over twenty years, which translates to a dramatic relative decline when the global pie tripled around it. Germany and France remain in the top ten but have not grown proportionally. Europe built social safety nets while Asia built stock markets. It is not that Europe got poorer — it is that Asia got richer faster, and the capital that might have flowed to European listings found more compelling returns in semiconductor-dense Taiwan, reform-driven India, and AI-exposed South Korea instead.
The most counterintuitive finding in this entire twenty-year dataset is the American story. The United States market capitalisation grew from approximately $19.3 trillion in 2006 to $75-79.5 trillion in 2026 — a four-to-five-fold increase in absolute terms that represents the largest single-country wealth creation event in capital markets history. And yet, even with this extraordinary absolute growth, the US has simultaneously seen its market capitalisation exceed 227% of its own GDP — a ratio that has no precedent in the history of the country, and that most serious economists view as either a sign of structural transformation or a warning signal, depending on their priors.
The US now represents approximately half of total global market capitalisation. A single country with roughly 25% of global GDP owns 50% of global stock market value. The seven largest US technology companies alone — Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta, Tesla — collectively represent more market value than the entire stock markets of most individual countries. Nvidia's market capitalisation at its 2024-2025 peak briefly exceeded the entire GDP of Germany. The AI investment surge of 2023-2026 added more to US equity market valuations in three years than China's entire stock market is worth today.
The $80 trillion in new market value created between 2006 and 2026 is not the same as $80 trillion in new real wealth for ordinary people. Market capitalisation is a claim on future earnings discounted to present value — it goes up when interest rates fall, when earnings expectations rise, or when investors assign higher multiples to existing earnings, regardless of whether the underlying economy produces more goods, services, or human welfare. Much of the market cap growth of this period reflects lower discount rates rather than higher real output, which is why the GDP-to-market-cap ratio has expanded so dramatically. The Letter 39 argument about GDP's limitations applies here too: stock market capitalisation is an even more abstract proxy for welfare than GDP, and the two have significantly diverged over this twenty-year period.
India's rise in this table deserves special emphasis because it is the story most likely to define the next twenty years rather than the last twenty. India at $5 trillion in 2026 is where China was approximately fifteen years ago. The reform agenda, the demographic dividend — a young, growing, English-speaking workforce — and the investment flows triggered by China+1 supply chain diversification (documented in Letter 38) are structural tailwinds that suggest India's market capitalisation trajectory over the next twenty years could replicate China's trajectory over the last twenty. That is not a guarantee. It is the single most important emerging market thesis available to a long-horizon investor in 2026.
Twenty years from now, someone will write the equivalent of this letter covering 2026-2046. The question they will be answering is whether the eastern pivot continued, whether the US concentration persisted or corrected, and which of today's emerging markets joined the table that India, China, Taiwan, and South Korea climbed into between 2006 and 2026. The data does not tell us the answer. What it does tell us is that the map of global capital rewrites itself dramatically over twenty-year periods — and that the investors who read the geographic shift early enough to position ahead of it, rather than after consensus formed, captured returns that the rear-view-mirror investors never did. The shift from two Asian markets to six happened gradually and then suddenly. The next shift is already beginning.
