OpenAI Revenue Miss Triggers Wave of AI Bubble Concerns, Market Rout

OpenAI's disclosure that its annualized revenue stands at $50 billion—sharply below the $70 billion previously reported to investors—sent shockwaves through equity markets on October 8, sparking a broader reckoning with months of unbridled optimism about artificial intelligence growth. The Nasdaq 100 slid 1.4%, marking its worst single day in seven weeks, while semiconductor stocks including Nvidia, Broadcom, and Micron Technology fell sharply. The S&P 500 declined 0.5%, though losses concentrated heavily in technology and AI-dependent sectors.
