Super Micro Computer (NASDAQ:SMCI) and CoreWeave (NASDAQ:CRWV) are having a big night on Wall Street, with both AI infrastructure stocks surging after reporting earnings Tuesday. Supermicro stunned the market with guidance far above expectations, while CoreWeave delivered another strong quarter and showed that customers are still lining up for its AI computing capacity.

Supermicro shares are up nearly 10% in after-hours trading after the AI server maker finished fiscal 2026 with largely in-line quarterly results but offered investors a much stronger outlook. Fiscal fourth-quarter revenue nearly doubled from a year earlier to $11.12 billion, coming slightly below the $11.26 billion analysts expected. Adjusted earnings reached $1.70 per share, beating Wall Street's $1.59 consensus estimate.

The real excitement, however, came from what Supermicro expects during the current quarter. Management forecasts adjusted earnings between $1.01 and $1.10 per share, topping the $0.72 analysts had penciled in. Revenue is expected between $14.5 billion and $15.5 billion, well above Wall Street's $11.82 billion estimate. Supermicro said it generated more than $60 billion in new orders during fiscal 2026 and entered the new fiscal year with record backlog.

Wall Street, meanwhile, is still keeping SMCI at arm's length. 8 of the 12 analysts covering the stock are staying on the sidelines, versus 3 bulls and one bear, leaving SMCI with a Hold (i.e. Neutral) consensus rating. The $38.40 average price target is more upbeat, implying about 21.5% upside from Tuesday's closing price. (See SMCI stock forecast)
