U.S. market cap hits about $77 trillion

FT Wilshire 5000 data showed U.S. stock market capitalization at about $74.7 trillion on May 14, 2026, not $77 trillion, based on the index’s published close for that session. Yahoo Finance’s historical data for the FT Wilshire 5000 Total Market Index showed a May 14 close of 74,706.84, up from 74,151.01 on May 13. The S&P 500 also set a record on May 14. CNBC, citing exchange data, reported the index rose 0.77% to close at 7,501.24, while the Nasdaq Composite ended at 26,635.22 and the Dow Jones Industrial Average at 50,063.46. The figures matter because investors often use the FT Wilshire 5000 as a shorthand for the total value of the U.S. equity market.

(cnbc.com) Yahoo Finance’s May 14 reading for the FT Wilshire 5000 was 74,706.84, which corresponds to roughly $74.7 trillion if the index level is read as billions of dollars. MacroMicro, which tracks the same series, showed nearby readings of 73,745.66 billion on May 12 and 73,928.39 billion on May 11. (wilshireindexes.com) The available source material reviewed here did not show an official May 14 reading at $77 trillion. That means the higher figure in social-media posts could reflect a different market-cap series, an intraday estimate, or an error, but no primary source reviewed for this story confirmed it. ### What exactly hit a record on May 14? (finance.yahoo.com) CNBC reported the S&P 500 closed at a record 7,501.24 on May 14. The same report said the Dow retook 50,000 and the Nasdaq also recorded a fresh all-time closing high. Yahoo Finance’s historical page showed the FT Wilshire 5000 closing at 74,706.84 on May 14, above 74,151.01 on May 13 and above 73,745.66 on May 12. (finance.yahoo.com) Those figures indicate a new high for the broad U.S. market gauge over that stretch. ### Was the recent rally unusually fast? The FT Wilshire 5000 rose from 65,820.02 on April 1 to 74,706.84 on May 14, according to Yahoo Finance historical data. (cnbc.com) That is an increase of about 13.5% over the period. The S&P 500’s move was also part of a broader rebound in large-cap stocks. CNBC quoted William Merz, head of capital markets research at U.S. (finance.yahoo.com) Bank Asset Management, as saying “it’s hard to look past the robust earnings growth story,” and that corporate fundamentals were “remarkably strong,” particularly for U.S. large-cap companies. ### What was happening in Treasury yields at the same time? The U.S. Treasury’s daily yield table showed 10-year, 20-year and 30-year constant-maturity yields above 4% and 5% in recent May readings. The Treasury page available through search results displayed the official daily curve data for 2026 and listed the 10-year, 20-year and 30-year series as part of that dataset. (cnbc.com) The specific yield figures cited in the social-media post — 10-year at 4.538%, 20-year at 5.092% and 30-year at 5.085% — were not independently confirmed from the official Treasury page in the material accessible here. A separate market summary cited lower May 14 readings of about 4.42% for the 10-year, 5.02% for the 20-year and 4.98% for the 30-year. (home.treasury.gov) ### Where can readers check the next update?
