New York, Feb 18, 2026, 17:07 EST — After-hours
- Microsoft closed in the U.S. at $399.60, a gain of $2.67 in the latest session.
- The stock caught a lift alongside a wider AI-fueled rally, as traders pointed to bargain-hunting in Big Tech.
- Microsoft’s latest spending plans are on investors’ minds, set against a backdrop of rate uncertainty and potential triggers in AI just ahead.
Microsoft (MSFT.O) climbed roughly 0.7% in after-hours action Wednesday, last changing hands at $399.60. Shares had closed the regular session in positive territory.
Technology shares found late support, pulling the Nasdaq up 0.78% and leaving the S&P 500 with a 0.56% gain. Nvidia advanced after announcing a multi-year agreement to supply millions of AI chips to Meta. Microsoft finished regular trading 0.7% higher, with other major tech stocks also climbing. “At a certain point, weakness in tech was bound to bring in the marginal buyer,” said Ross Mayfield, investment strategy analyst at Baird. 1
The clock is ticking for Microsoft’s budget, with the company reaffirming its commitment to pouring $50 billion into expanding artificial intelligence across the “Global South” before the decade wraps up. That term covers developing and lower-income nations, and Microsoft flagged last year’s $17.5 billion AI investment package in India as a key milestone. 2
The question dogging investors hasn’t changed: when will AI-driven costs actually pay off in sustained profit? Last month, Microsoft spotlighted record spending tied to AI, while cloud growth slowed—a combination that sent the stock wobbling and fueled fresh skepticism over data-center investments. “One big obvious issue is that revenues are up 17% and the cost of revenues are up 19%,” said Eric Clark, portfolio manager of the LOGO ETF, which owns Microsoft shares. 3
The regulatory cloud isn’t going anywhere. According to Bloomberg, the U.S. Federal Trade Commission has ramped up its examination of Microsoft’s cloud and software licensing moves, asking competitors for details on how AI, security, and identity products are bundled. Even if no fines land soon, the process has a way of lingering and pulling management’s attention. 4
Rates are still in motion. On Wednesday, the Fed published minutes from its January meeting, with the next policy call coming up March 17-18. 5
Thursday’s action hinges on data. Investors will watch for U.S. reports Feb. 19, with weekly initial jobless claims and the trade deficit on the docket. These numbers could rattle rate bets and, in turn, move long-duration tech valuations. 6
Setting aside the big-picture moves, there’s a concrete deadline for the AI trade: Nvidia drops its numbers Feb. 25. That’s not just Nvidia’s problem. Microsoft’s exposure isn’t direct, but it’s tangible—chip flows, price tags, and demand trends filter straight into what it costs and how fast they can expand their cloud footprint. 7
After-hours action tends to be sparse, with late trades sometimes stretching minor moves. Even so, on Wednesday, the tape suggested buyers weren’t shy about wading back into mega-cap tech stocks at the first sign that AI demand remains firm.
Microsoft’s rally faces a test on Thursday, as traders eye jobless claims at 8:30 a.m. ET. Nvidia’s Feb. 25 report looms too, with positioning for that event high on the list.
