New York, Jan 26, 2026, 17:23 EST — Trading after hours.
CoreWeave (CRWV.O) shares jumped 5.7%, closing at $98.31 on Monday following Nvidia’s announcement of a $2 billion investment in the cloud company. Nvidia (NVDA.O) dipped 0.7% to $186.47 in late trading. Meanwhile, Microsoft (MSFT.O) climbed 0.9%, and Broadcom (AVGO.O) added 1.5%.
The deal cast a new light on the infrastructure fueling the AI boom — data centers, power, and the chips inside them. Investors are now pressing a sharper question: when will all this investment translate into earnings, rather than just making headlines.
U.S. stocks closed up as investors braced for a busy week packed with megacap earnings and a two-day Fed meeting. “Investors are cautiously optimistic and most likely looking forward to earnings season,” said Chris Zaccarelli, chief investment officer at Northlight Asset Management. 1
Nvidia plans to buy CoreWeave shares at $87.20 each, adding about 23 million shares and nearly doubling its stake. The move has sparked investor concerns over circular financing. CoreWeave, a so-called neocloud—a newer cloud provider leasing computing power—aims for more than 5 gigawatts of AI data-center capacity by 2030. “Nvidia is the leading and most requested computing platform at every phase of AI,” CoreWeave CEO Michael Intrator said. A spokesperson clarified that the cash will fund data-center expansion, R&D, and hiring, not chip purchases. 2
Microsoft, a major Nvidia client, is moving to internalize more of its tech stack. It revealed its second-generation Maia 200 AI chip and plans to integrate it with software tools based on open-source Triton — a direct challenge to Nvidia’s CUDA, the widely used programming toolkit for developing on Nvidia hardware. 3
Cloud giants still snap up Nvidia’s processors despite developing their own custom chips, but the trend shapes market sentiment. Traders are on alert for hints that Nvidia’s software edge might be slipping or that its largest customers are tightening the tap on upcoming data-center purchases.
Tesla (TSLA.O), a stock closely linked to the AI story, is set to report earnings Wednesday, with the spotlight on self-driving tech and related software income. “For 2026, you’re essentially seeing if AI becomes revenue + profit, not just spend as it is mostly now,” said Ken Mahoney, CEO of Mahoney Asset Management. 4
That said, the situation cuts both ways. Should this week’s earnings calls reveal slower build-outs, rising costs, or stretched payback timelines, the AI sector could reverse sharply—particularly after a rally that already squeezed valuation cushions tight.
The Fed’s policy announcement comes Wednesday, followed by a wave of earnings reports seen as signals for AI-driven spending and capital investment. Microsoft will report quarterly results after the market closes on Jan. 28; Meta is set to do the same that day. Apple’s fiscal first-quarter earnings call is scheduled for Jan. 29. 5
