US stock markets today: US stocks rise after Anthropic announces new AI tools; tariff worries persist

U.S. stock indexes edged higher on Tuesday, boosted by technology shares as investors weighed Anthropic's announcement of new AI tools as well as President Donald Trump's shifting stance on trade policy.

Artificial intelligence lab Anthropic announced 10 new ways ‌for business customers to ⁠plug ⁠in its technology to key areas of their work, weeks after its earlier releases stoked a selloff of traditional software stocks.

The company said its new plug-ins were developed jointly with partners, among them Thomson Reuters, which owns Reuters news agency, Salesforce and FactSet.


FactSet shares climbed 3.8%, while U.S.-listed shares of Thomson Reuters jumped 8.8%.

Salesforce advanced 3.4%, making it one of the biggest gainers on the blue-chip Dow along with Home Depot , which was up 2.7% after the home-improvement chain operator topped estimates for fourth-quarter results and maintained its annual forecasts.

The S&P 500 software and services index climbed 0.5%, recovering some losses. It has plunged 23.5% so far this year as ⁠the sector ‌grapples with AI-disruption fears.

At 10:10 a.m. ET, the Dow Jones Industrial Average rose 289.29 points, or 0.59%, to 49,093.35, the S&P 500 gained 19.31 points, or 0.28%, to 6,857.06, and the Nasdaq Composite was up 114.05 points, ⁠or 0.50%, to 22,741.33.

Advanced Micro Devices jumped 6.7% after the chipmaker said it had agreed to sell up to $60 billion worth of AI chips to Meta Platforms over five years.

Most megacap and growth stocks were higher, with Apple leading gains at a 3% rise, though Alphabet and Nvidia lagged with a near 1% fall each.

Nvidia's quarterly earnings, due after market close on Wednesday, will draw intense scrutiny from investors.

All three main indexes fell more than 1% on Monday, with financials and software stocks among the worst hit as the fallout from Friday's U.S. Supreme Court ruling on Trump's tariffs caused an exodus from high-risk equities.

After Friday's ruling, Trump announced a temporary global tariff of 10%, which came ‌into effect on Tuesday. He later said the levy would be 15%, but it was unclear when and if this would apply.

"The market doesn't only have one particular worry... the AI trade has certainly become a worry for the market, but then there are geopolitical ⁠concerns, macro concerns and of course, the tariff concerns," said Peter Cardillo, chief market economist at Spartan Capital Securities.

Analysts also attributed Monday's selloff to a bearish report from Citrini Research outlining potential threats to the global economy from the rise of artificial intelligence.

February has been a dour month for U.S. shares as high stock valuations and AI concerns pressure technology and other sectors, with investors questioning if massive AI spending was actually paying off.

Among other stocks, Keysight Technologies climbed 20.5% after the electronic-equipment maker forecast second-quarter profit ahead of Wall Street estimates.

Advancing issues outnumbered decliners by a 1.34-to-1 ratio on the NYSE and by a 1.65-to-1 ratio on the Nasdaq. The S&P 500 posted 27 new 52-week highs and 11 new lows, while the Nasdaq Composite recorded 60 new highs and 117 new lows.
