AI Stock Rout and Volatile Markets Ahead of a Crowded Week

AI and chip stocks reportedly lost about $5 trillion in October while the rest of the large-cap group gained; futures have since rebounded modestly. Investors are watching whether AI spending can deliver durable earnings, alongside Apple and Palantir results, the midterms, the Bank of England and Friday’s jobs report. Market roundups also cited a reported $115 billion Marvell–Lumentum deal and Binance’s claim it covered about 90% of hack-affected funds; the selloff alone does not prove an AI bubble has burst.
