Grok 4.5 Launches as Tech Stocks Lose $820 Billion Amid Mixed AI Earnings - Tekedia

xAI launched Grok 4.5 as tech stocks were hit by a sharp sell-off tied to mixed AI earnings.

The rout erased about $820 billion in market value, showing investors are rethinking AI valuations.

Tesla sank after a weak earnings report and a large capex plan, while Intel rose on stronger AI-chip and data center demand.

The market reaction suggests AI progress alone is no longer enough; profits and spending discipline now matter more.
