What happened
US tech megacap shares tumbled Monday, with SpaceX (SPCX.O) sliding over 10% post-IPO. Alphabet (GOOGL.O) dropped 6%, erasing over $256 billion in market value, following Google DeepMind's John Jumper's exit to Anthropic. Amazon (AMZN.O) lost 4.8%, while Meta Platforms (META.O) and Microsoft (MSFT.O) eased around 3% each, collectively losing over $248 billion. Investors cited concerns over hyperscalers' massive AI infrastructure spending without clear evidence of justifying returns. Conversely, Micron Technology (MU.O) gained 5.8% to record highs, announcing a strategic agreement with Anthropic.
Why it matters
Investor scrutiny on AI spending intensified, driving down megacap valuations as returns on massive infrastructure investments remain unproven. This shift impacts founders seeking capital and procurement teams evaluating long-term AI platform commitments, demanding clearer ROI metrics. Hyperscalers' capital expenditure, previously seen as necessary for AI leadership, now faces direct market pressure, contrasting with the half-trillion dollars borrowed by Big Tech for AI this year. Chipmakers like Micron, however, benefit directly from this infrastructure build-out, securing strategic partnerships.
