OpenAI Growth Misses Spark AI Sector Sell-Off

Reports that OpenAI missed internal goals for annual revenue and a target of 1 billion weekly active ChatGPT users have triggered a broad sell-off in AI-related stocks. The company has ceded market share in the enterprise and coding sectors to rivals Google Gemini and Anthropic, leading to internal friction over infrastructure spending. CEO Sam Altman committed approximately $600 billion to future computing capacity, but CFO Sarah Friar warned that the company may struggle to fund these contracts without accelerated growth and questioned its readiness for a potential IPO.

OpenAI dismissed claims of internal misalignment as "ridiculous" and stated the business is "firing on all cylinders." Despite the defense, the news caused shares of key partners to slump, including Oracle, CoreWeave, SoftBank, and Nvidia. Investors expressed growing concern over whether the massive capital expenditures of AI "hyperscalers" are generating sustainable returns. This volatility occurred just as Alphabet, Amazon, Meta Platforms, and Microsoft released simultaneous quarterly earnings reports on April 29, 2026.

While these four giants reported strong cloud growth and beat most Wall Street expectations, the results were mixed. Alphabet's Google Cloud grew 63%, but Meta's stock fell after the company raised its minimum capital expenditure projection to $125 billion. Collectively, these firms plan to spend $650 billion on AI infrastructure in 2026, a trend coinciding with significant workforce reductions at Meta, Amazon, and Microsoft as they integrate AI to replace or amplify human labor.
