NEW YORK, Jan 27, 2026, 06:26 EST — Premarket
- CoreWeave, supported by Nvidia, gained in premarket following the chipmaker’s announcement of a $2 billion investment.
- Alphabet is under renewed EU scrutiny concerning access to Google Search data and its Gemini AI features.
- Investors are turning to Wednesday’s Microsoft earnings and the Fed’s latest moves for clues on AI spending.
Nvidia announced a $2 billion investment in AI cloud provider CoreWeave, purchasing shares at $87.20 each and nearly doubling its stake as both companies work to boost U.S. data-center capacity. CoreWeave CEO Michael Intrator highlighted the deal as proof of “the strength of demand” from their clients. CoreWeave’s shares rose 5.7% in Tuesday’s U.S. premarket trading, while Nvidia’s slipped 0.7%. 1
The focus has shifted to money as the market wrestles with who will foot the bill for the next AI expansion — and who will see returns, and on what timeline. The winners have been obvious for months; now the discussion centers on financing, margins, and the durability of the spending cycle.
Neoclouds—a name investors give to newer cloud outfits leasing AI computing hardware—have emerged as a key stress spot. These firms operate between chip makers and Big Tech customers, with blurred boundaries since many back each other financially.
Nvidia pushed the AI narrative past data centers on Monday, unveiling three open-source “Earth-2” models for weather forecasting at a meteorology conference in Houston. “The tension is gone, because once trained, AI is 1,000 times faster,” said Mike Pritchard, Nvidia’s director of climate simulation research. 2
Alphabet took center stage as EU regulators launched proceedings aimed at defining how Google must grant rival search engines and AI developers access to elements of its services, including those linked to Gemini. Google pushed back, warning in a statement from senior competition counsel Clare Kelly that new rules “will compromise user privacy, security, and innovation.” 3
In premarket trading, other AI-focused megacaps climbed: Alphabet gained 1.6%, Microsoft added 0.9%, and Broadcom rose 1.5%. Meanwhile, AMD slipped 3.3%, trailing its chip sector rivals in early action.
Microsoft will release its fiscal second-quarter earnings after the market closes Wednesday, followed by a call at 2:30 p.m. Pacific. Investors will be watching closely for updates on cloud revenue and any details about the expenses tied to expanding its AI infrastructure. 4
Macro factors remain in focus. The Federal Reserve wraps up its two-day meeting Wednesday, with rates likely to stay within the 3.50%-3.75% band. Growth stocks with longer durations could feel the squeeze if officials signal caution around easing. 5
However, traders remain cautious. Should Microsoft signal tighter capacity limits, a jump in capex, or softer near-term returns, investors could pull back sharply from AI infrastructure stocks. On top of that, regulatory uncertainty in Europe complicates the outlook for Alphabet and its rivals.
Wednesday brings a packed schedule: Microsoft will report earnings after the bell, then the Fed will announce its decision, capped by Chair Jerome Powell’s press briefing.
