Global stock market cap reaches 137% of GDP, near record high

Global stock market value hit a record $166 trillion this month, with the U.S. accounting for about $77 trillion, as AI-driven gains helped push valuations toward 2021 meme-stock-era extremes.

Fact Check
The claim traces to The Kobeissi Letter's July 26, 2026 post. Its headline figures are independently corroborated: record $166T global equity market cap appears across multiple mid-2026 sources, and one report cites a ~134% market-cap-to-GDP ratio weeks earlier, consistent with 137% by late July. Global GDP (~$121-124T for 2026) makes the 137% ratio arithmetically sound (166/121≈137%). The elevated Buffett-Indicator/valuation context and 2021 meme-stock comparison are supported by Reuters. The +40pp-since-April-2025 and exact ~120% pre-2008 peak figures rely primarily on Kobeissi's own methodology and were not independently confirmed, so confidence is medium rather than high, but no source conflicts with the claim.
Summary

Global equity market capitalization has climbed to 137% of global GDP, leaving the widely watched valuation gauge near its highest level on record. The ratio has risen 40 percentage points since April 2025, returning to levels last seen during the 2021 meme stock frenzy and surpassing the roughly 120% peak cited before 2008. Global stock market value reached a record $166 trillion this month, with the U.S. accounting for about $77 trillion, or roughly 46% of the total. The Kobeissi Letter said AI is driving historic gains, reinforcing how far asset values have outpaced underlying economic output.
