Stocks were mostly higher on Monday as investors embraced risk and artificial intelligence and continued to shrug off the government shutdown, now in its sixth day.
These stocks made moves:
Advanced Micro Devices soared 24% after announcing that it had struck a multibillion-dollar agreement with OpenAI. As part of the deal, OpenAI will take a 10% stake in the chip maker and buy six gigawatts worth of AMD’s chips starting with the MI450 chip next year, the companies said.
Regional lender Comerica jumped 14% after Fifth Third Bancorp said it would buy its smaller peer for $10.9 billion. The transaction, which is expected to close by the end of the first quarter 2026, would create the ninth-largest U.S. bank with some $288 billion in assets, the companies said. Fifth Third shares fell 1.4%.
Tesla rose 5.5%. Shares of the electric-vehicle maker fell 1.4% on Friday and finished the past week down 2.4%, even though the Elon Musk-led company posted third-quarter deliveries that were better than expected. The stock has gained 11% this year.
Palantir Technologies was up 3.7%. Shares of Palantir, which sells artificial-intelligence software to manage and analyze large amounts of data, fell 7.5% on Friday after a report said there were security flaws in a communications platform designed for the Army. A Palantir spokesperson told The Wall Street Journal that the “security review process during the experimental phase of NGC2 functioned as designed.” Palantir is developing NGC2 with Anduril Industries.
UiPath was up 13%. The automation software company has announced a slew of partnerships with several AI heavyweights including OpenAI and Nvidia. Shares gained nearly 6% last week.
Coinbase Global rose 1.6%, building on a 55% gain so far this year. Shares were boosted by the price of Bitcoin hitting a record high over the weekend. The price of the world’s largest cryptocurrency was up 2.5% over the past 24 hours to $125,740, according to CoinDesk data.
Quantum Computing was down 10% after announcing that it planned to raise $750 million in an oversubscribed private placement. The company said it had entered into agreements with institutional investors for the sale of more than 37 million shares of company stock.
Rigetti Computing, another quantum-computing company, gained 4.1% after rising 13% on Friday to close at a record of $40.06. The stock has finished higher for five consecutive sessions and has gained more than 35% over the period, according to Dow Jones Market Data. Rigetti jumped more than 28% last week, boosted by an announcement that it had secured purchase orders for two Novera quantum-computing systems.
D-Wave Quantum was up 7%. It also hit a record high Friday, gaining 12% to close at $32.70.
Paramount Skydance was up 0.2%. The company confirmed it was acquiring The Free Press, the media company founded by former New York Times journalist Bari Weiss, and naming Weiss as editor in chief of CBS News.
Plug Power climbed 8.7%, extending gains from last week. Shares surged 34% on Friday after H.C. Wainwright analyst Amit Dayal raised his price target to $7 from $3, arguing that higher electricity prices help make hydrogen technology more competitive.
Constellation Brands declined 2.5% ahead of its fiscal second-quarter numbers, expected after the close. Analysts tracked by FactSet expect the beer distributor to report adjusted earnings of $3.38 per share. Sales are forecast to decline 16% from the year-ago quarter to $2.46 billion. Coming into Monday, the stock was down 36% this year.
Reports are expected later in the week from Delta Air Lines, PepsiCo, McCormick, Penguin Solutions, Levi Strauss, Applied Digital, and Neogen.
