US stocks set more records as Wall Street's relentless rally keeps rolling

NEW YORK (AP) — The seemingly relentless rally on Wall Street drove U.S. stocks to more records on Monday.

The S&P 500 rose 0.4% after erasing a modest loss from the morning. The Dow Jones Industrial Average added 66 points, or 0.1%, and the Nasdaq composite climbed 0.7%. It's the third straight day where all three indexes set an all-time high.

“Every time the market seems to be running out of momentum, it fools most of us by pushing to higher heights,” said Jay Woods, chief market strategist at Freedom Capital Markets.

A familiar face was again the strongest force lifting the market, Nvidia. Wall Street’s most valuable company rose 3.9% after announcing a partnership to train and run OpenAI’s next generation of artificial-intelligence models. As part of the deal, Nvidia will invest up to $100 billion in OpenAI.

Oracle also pushed the market higher after climbing 6.3%. A senior official in President Donald Trump’s administration said the tech giant will receive a copy of TikTok’s algorithm to operate for U.S. users, part of the deal to keep the popular platform running in the country.

Oracle also named Clay Magouyrk and Mike Sicilia as its CEOs, with current CEO Safra Catz becoming executive vice chair of the technology company’s board.

Some of the market’s sharpest action was among companies agreeing to buy one another.

Pfizer said it would buy Metsera and its pipeline of medicines to potentially treat obesity in a deal initially valuing it at $4.9 billion. The payout for Metsera investors could go up sharply if its candidates win approval from federal regulators and achieve other milestones.
