CoreWeave shares tumble about 10% amid OpenAI revenue worries and tech sector weakness

On October 8, 2026 CoreWeave stock slipped roughly 10% to around $81 after briefly trading above $90. The decline was sparked by a Financial Times report that OpenAI revenue is about $20 billion below expectations, heightened put activity, and broader weakness in technology shares. CEO Michael Intrator sold 200,000 shares at prices between $85.57 and $88.95. The company also announced a $3 billion convertible debt offering and an at‑the‑market equity issuance of up to 35 million shares.

The slide erodes CoreWeave’s market value and may increase scrutiny of the planned $3 billion financing, which the company says will fund its infrastructure expansion.
