CoreWeave (NASDAQ: CRWV), Nebius (NASDAQ: NBIS), and Supermicro (NASDAQ: SMCI) each delivered strong quarterly results, sending shares surging as investor confidence in the AI build-out held firm.

CoreWeave stock jumped as much as 20% on Wednesday, while Supermicro climbed roughly 15% and Nebius led all three with a gain of approximately 27%.

The results suggest that demand for computing power remains intense, with businesses showing little hesitation in paying premium prices to secure access to as much compute as possible.

Nebius posted quarterly revenue of $582.3 million, a staggering 454% year-over-year increase from $105.1 million in the same period the prior year.

The company signed four major AI cloud deals during the quarter, with the average total contract valued at more than $1 billion, signaling robust and sustained enterprise demand.

Nebius noted it could sell out all of its 2027 capacity but is deliberately holding some back to meet immediate customer requirements.

To fuel that growth, Nebius spent $5.7 billion on capital expenditures during the quarter, driven primarily by GPU purchases and GPU-related hardware investments.

CoreWeave also delivered a breakout quarter, with revenue rising 112% to $2.5 billion, up from $1.2 billion in the same period last year.

The company’s revenue backlog grew 246% to $104.2 billion, and CoreWeave disclosed it had already signed an additional $25 billion in deals set to appear in its third-quarter backlog figures.

CoreWeave’s capital expenditures for the quarter reached $9.4 billion, while adjusted net losses widened to $567 million compared with $130 million in the year-ago period.

Supermicro delivered adjusted earnings per share of $1.70, topping analyst expectations of $1.59, though revenue of $11.1 billion fell marginally short of the $11.2 billion consensus forecast.

The company issued forward guidance projecting net sales of between $14.5 billion and $15.5 billion, well ahead of the $11.9 billion Wall Street had been anticipating.

Across all three companies, the common theme is clear: computing constraints remain acute, and capital is flowing heavily into the infrastructure required to meet that demand.

Despite the broadly positive results, the AI trade has historically been subject to sharp swings in sentiment, with investors frequently debating whether a market peak is approaching or further growth remains ahead.

The next major test for AI infrastructure sentiment arrives when Nvidia (NASDAQ: NVDA) reports its second-quarter earnings on August 26, a result that could set the tone for the sector heading into the back half of the year.
