The US stock market just crossed a threshold that makes the rest of the world look like a rounding error. American equities now sit at approximately $81 trillion in total market capitalization, representing 48% of the entire global equity market, according to data from Bloomberg Finance LP and Deutsche Bank Research highlighted by The Kobeissi Letter.
To put that in perspective, the global equity pie is roughly $167 trillion. The US takes nearly half of it. China, the world’s second-largest economy, commands about $17 trillion in equity value. That means the US market is roughly 375% larger than China’s.
The $12 trillion sprint
What makes this number especially striking is the velocity. On January 1, 2026, US market capitalization stood at approximately $69 trillion. In roughly six months, American stocks added about $12 trillion in value.
The US market now exceeds the combined equity markets of China, Japan, Hong Kong, and Taiwan.
