US stocks opened higher on Wednesday, supported by strong gains in CoreWeave and a rebound in Nvidia as investors reassessed concerns about artificial intelligence spending and infrastructure demand.
The Nasdaq Composite advanced 1.44%.
The Dow Jones Industrial Average was down 68 points, while the S&P 500 gained 0.84%.
CoreWeave shares jumped more than 12% in trading after the cloud computing company reported better-than-expected third-quarter revenue and raised its 2026 revenue and operating income guidance.
The company also said it expects to become profitable on an adjusted basis in the first half of 2028.
The results helped ease concerns about the sustainability of AI infrastructure investment, which has weighed on technology stocks in recent sessions.
CoreWeave earnings lift AI infrastructure stocks
CoreWeave’s results supported a broader recovery across companies exposed to AI infrastructure spending.
Nebius Group and Applied Digital gained 12.19% and 6.38%, respectively.
Both companies have faced pressure amid concerns about the returns on large investments in data centres and computing capacity.
The rebound also extended to semiconductor stocks.
Nvidia rose 2.9% in trading after losing around $430 billion in market value over the previous two sessions.
Marvell Technology advanced 6.5%, while Micron gained 5.8%.
Data storage companies also recorded strong gains, with Seagate Technology rising 6.57% and Western Digital adding 4.6%.
CoreWeave’s performance has become an important indicator of investor confidence in the AI infrastructure sector.
Its debt-funded expansion had raised questions about whether demand and customer commitments would be sufficient to support its spending plans.
The company’s latest results helped ease some of those concerns, although investors remain focused on the sustainability of capital expenditure across the industry.
Nvidia rebounds as investors reassess AI outlook
Nvidia shares recovered after a difficult start to the week, when reports about CEO Jensen Huang’s relationship with a Chinese businesswoman allegedly linked to espionage raised concerns.
The chipmaker had fallen nearly 10% over the previous two sessions, contributing to losses across the broader technology sector.
The latest rebound helped lift sentiment among semiconductor companies, although uncertainty surrounding Nvidia’s leadership and the outlook for AI investment remains.
Investors are also assessing Anthropic’s planned initial public offering.
The Claude chatbot developer is targeting a valuation of up to $1.4 trillion and could raise as much as $64.4 billion through the share sale.

Fed rate expectations remain a concern for markets
Despite the recovery in technology stocks, concerns about monetary policy continued to weigh on the broader market outlook.
October’s US Consumer Price Index rose 0.4% month over month, exceeding economists’ expectations and strengthening expectations of a Federal Reserve rate increase in December.
Markets are pricing in a near-certain quarter-point increase, while the probability of a larger 50-basis-point move has risen to around 13.2%, according to CME FedWatch data.
Fed Governor Christopher Waller has indicated that policymakers should consider a larger increase if inflation worsens.
Other market participants also expect the central bank to maintain a restrictive approach until price pressures ease.
Higher interest rate expectations have added to volatility in equities, particularly among technology companies whose valuations are sensitive to borrowing costs.
Meanwhile, oil prices recovered by more than 1% on Wednesday after falling to two-month lows in the previous session.
