The U.S. stock market delivered a historic performance in May 2026, with all three major indexes closing at fresh all-time highs on the final trading day of the month, May 29.
A powerful rally in technology stocks, strong corporate earnings, easing inflation pressures, and positive geopolitical developments helped drive the market’s strongest monthly gains of the year.
For the month, the market’s three major indices performed as follows:
S&P 500 5.2%
The Dow 3.1%
Nasdaq Composite 8.4%
The S&P 500 closed out May at a record 7,580.06. The benchmark index also recorded its ninth consecutive weekly gain, reflecting broad investor confidence and sustained market momentum.
Technology stocks led the market’s advance, particularly companies benefiting from growing demand for artificial intelligence infrastructure. So it’s no surprise that the tech-heavy Nasdaq Composite finished at a record 26,972.62, significantly outperforming the other major indexes.
The Dow Jones Industrial Average also reached a historic milestone, crossing the 51,000 mark for the first time. The blue-chip index ended May at 51,032.46, posting a gain of approximately 3.1% for the month.
