CoreWeave and Super Micro jump after upbeat AI capacity forecasts
CoreWeave said its revenue backlog rose to $104.2 billion in the second quarter, while Super Micro reported a 17.5% gross margin in its latest quarter.
CoreWeave and Super Micro Computer shares surged to their highest levels since June after both companies delivered forecasts viewed as signaling strong demand for AI computing capacity, according to Yahoo Finance. CoreWeave climbed more than 19% and Super Micro rose more than 13% following guidance updates made a day after their upbeat outlooks, placing them at the center of the AI infrastructure buildout but with different operating models, one leasing compute capacity and the other selling physical servers.
For CoreWeave, the company raised its annual revenue, adjusted operating profit, and capital spending forecasts after its August 11, 2026 earnings report, with its revenue backlog increasing to $104.2 billion in the second quarter from $99.4 billion three months earlier. The backlog figure did not include more than $25 billion in new commitments signed early in the current quarter.
Super Micro forecast fiscal 2027 revenue above Wall Street estimates, and its fourth-quarter gross margin came in at 17.5%, above both its preliminary 15% to 17% range and its earlier forecast of 8.2% to 8.4%. The article also notes CoreWeave has funded most construction and development through debt, and that investor focus on default risk among heavily indebted hyperscalers has intensified alongside AI capital spending.
