US stock markets hit record closing highs as AI-linked technology shares rally and a 60-day ceasefire agreement with Iran eases oil market concerns.

U.S. equities concluded the month of May with record closing highs, as strong performance in the technology sector and a new diplomatic development in the Middle East bolstered investor sentiment [2]. The S&P 500, Nasdaq Composite, and Dow Jones Industrial Average all reached fresh all-time intraday and closing peaks during the final session of the month [2].

**Key takeaways**
* The Nasdaq Composite rose 0.2% to close at 26,972.62, while the S&P 500 climbed 0.22% to 7,580.06 [2].
* Dell Technologies shares surged nearly 33% after the company reported a quarterly earnings beat and raised its full-year guidance [2].
* Oil prices dropped significantly, with WTI futures falling 1.73% to $87.36 per barrel following news of a 60-day ceasefire memorandum with Iran [2].
* The Nasdaq led monthly gains with an advance of over 8%, while the S&P 500 and Dow rose 5% and nearly 3%, respectively [2].

## AI Infrastructure Drives Market Momentum
The rally was largely fueled by optimism surrounding artificial intelligence, with technology stocks leading the market higher [2]. Dell Technologies emerged as a standout performer, recording its best day on record after exceeding expectations for both revenue and earnings [2]. Analysts noted that Dell’s performance highlights a shift in investor focus toward the broader AI infrastructure stack, moving beyond just chip and memory manufacturers [2]. Other tech firms also saw significant growth, with Micron Technology and Qualcomm rising 5% and 3% respectively on Friday, contributing to substantial gains for the month [2].

## Geopolitical Shifts and Energy Markets
Market sentiment was further supported by the announcement of a 60-day memorandum of understanding between the U.S. and Iran to extend a ceasefire [2]. President Donald Trump stated he was meeting in the Situation Room to finalize the determination, emphasizing that Iran must agree to never pursue a nuclear weapon and that the Strait of Hormuz must remain open [2]. This development helped alleviate some of the geopolitical uncertainty that had previously pressured energy markets [2]. Consequently, crude oil prices saw their largest monthly decline since April 2025, with Brent crude settling at $92.05 per barrel [2].

## Why it matters
The combination of strong corporate earnings and a cooling of Middle East tensions has provided a clear path for equities to continue their upward trajectory [2]. While investors remain mindful of potential "black swan" risks, the recent market behavior suggests that much of the geopolitical volatility has already been priced in [2]. As the market moves into the next month, the focus remains on whether the current AI-led infrastructure boom can sustain the momentum seen throughout May, particularly as the Federal Reserve continues to navigate a landscape of elevated inflation and shifting interest rate expectations [1, 2].
