❯ Nvidia closes up 8.74%, adding $442 billion in market value in a single day

post-earnings jumpNvidia closed Thursday up 8.74% at $227.98, adding $442 billion in market value in one session — the second-largest single-day gain by any stock on record. The trigger was its just-reported second quarter: revenue of $96.2 billion, more than doubling year over year and beating the $92.2 billion analysts expected, with non-GAAP earnings of $2.22 a share, above the $2.06 to $2.09 range forecast.

the guidance did itWhat actually turned positioning was the next quarter. Nvidia guided to $105.84 billion to $110.16 billion in third-quarter revenue, implying 85.7% to 93.2% growth against $57.01 billion a year earlier. The worry going in had been that hyperscalers were slowing purchases and AI demand had peaked. Jensen Huang told the call that AI infrastructure buildout “is at full steam,” and addressed the “circular financing” criticism head-on.

who has to rethinkOne earnings report pushed the skeptics back down the whole AI trade. Hedge funds short AI capex have to redo their assumptions first: if hyperscaler orders hold into the first half of next year, the peak-demand premise collapses. Index funds cannot sidestep it either — Nvidia alone carries close to an 8% weight in the S&P 500, so its swings rewrite the risk exposure of passive money that never chose to buy AI at all.
