Why Meta Platforms Stock Reversed Today

META fell 3.4% today after Goldman Sachs issued a profitability warning on AI hyperscalers, reversing yesterday's 4.5% gain tied to the company's Muse AI agent launch. GS analysts flagged that hyperscalers are projected to spend $800 billion in capital investments this year and $1.1 trillion next, but would need to generate $300 billion annually just to break even and $1 trillion annually to deliver meaningful profits.

The warning raises questions about whether META and its peers can monetize their massive AI infrastructure buildouts. META has been among the most aggressive spenders in AI compute capacity, betting that early-scale advantages in models like Muse will translate to advertising and enterprise revenue. Goldman's math suggests the revenue ramp needs to be steep and sustained.

The swing from Tuesday's 4.5% rally to today's 3.4% decline underscores how sensitive META has become to AI investment narratives. The stock is caught between enthusiasm for product launches and skepticism about capital efficiency.
