Wall Street climbs as investors await Nvidia results on AI demand

Nvidia’s earnings have turned into the market’s sharpest concentration-risk test. Wall Street climbed on Wednesday as the Nasdaq led gains, chip stocks rebounded and Nvidia rose 0.7% ahead of its results, while Marvell Technology jumped 7.8%, Intel added 6.3% and Micron gained 3.6%. The Philadelphia Semiconductor Index advanced 2.9%, eight of the 11 main S&P 500 sectors were in the green and technology led the way. The broader rally came even as the benchmark 10-year Treasury yield, which touched a 16-month high in the previous session, eased to 4.651% from 4.687%, a reminder that traders were buying semiconductors while still watching bond-market stress.

That is why Nvidia now functions as a referendum on the entire AI trade. Options pricing suggested the stock could move about 6.5% in either direction after the report, a swing of roughly $355 billion in market value, which is more than the individual market capitalization of about 90% of S&P 500 constituents. “I think investors have become complacent about AI/capex,” said Matt Amberson, founder of ORATS, capturing the tension between momentum and fundamentals. Nvidia was no longer being judged as a single chipmaker; its numbers were being read as a signal for AI infrastructure spending across equipment makers, cloud providers and the rest of the technology complex.

The company’s own scale explains the pressure. Nvidia’s investor-relations calendar listed 1st Quarter FY27 financial results for May 20, 2026, with the webcast set for 2 p.m. Pacific, 5 p.m. Eastern. Its most recent reported quarter, for fiscal 2026, delivered record revenue of $68.1 billion, up 73% from a year earlier, including record data center revenue of $62.3 billion, up 75%. Jensen Huang said computing demand was “growing exponentially,” and the company said enterprise adoption of AI agents was surging. Those figures set a high bar for the next report, because anything short of another blowout would raise questions about whether AI spending is still accelerating or simply running ahead of itself.

The spending backdrop has only sharpened that scrutiny. A CNBC report cited forecasts that combined 2026 capital expenditures from Alphabet, Amazon, Meta and Microsoft could approach $700 billion as the four hyperscalers build AI infrastructure. In April, U.S. chip stocks hit record highs after Intel issued an unexpectedly strong revenue forecast, and the Philadelphia Semiconductor Index later logged an 18th straight day of gains, underscoring how much of this year’s equity strength has been concentrated in semiconductors. Wednesday’s advance showed investors were still willing to own the trade, but Nvidia’s report will determine whether that rally rests on durable corporate demand or on a momentum cycle that has lifted the whole market with it.
