Michael Burry locked in a rapid 50% to 60% profit on Nvidia December call options less than 24 hours after opening the position, selling half the contracts after shares jumped roughly 9% on better-than-expected results. The Big Short investor framed mid-to-high $200s strike calls bought ahead of the print as insurance for a larger bearish book, saying their cost was entirely offset by shorts and puts, with Nvidia puts alone about 3.5% to 4% of his portfolio and short-stock exposure excluding puts above 21% across Nvidia, Oracle, Palantir, Nebius and Caterpillar. Nvidia reported $96.2 billion in quarterly revenue, more than double a year earlier, and adjusted EPS of $2.22; the stock later closed up 8.74% at $227.98, adding $441.5 billion in market value to reach about $5.49 trillion, with first-time definitive guidance of 70% fiscal 2028 revenue growth. Burry said the calls did their job and he might exit the rest, while still seeing little near-term obstacle to further gains and keeping a negative long-term view on AI infrastructure durability. He also held longer-dated Microsoft LEAP calls that benefited from a more than 15% post-earnings surge and separately flagged weak Build-A-Bear guidance after that stock fell more than 27%.
