Soros Fund Management and Appaloosa Management sharply boosted their Nvidia holdings in Q2, underscoring conviction in the chipmaker’s central role in the AI boom.

• Soros Fund: Bought 932,539 Nvidia shares (including puts and calls), a 1,600%+ increase, lifting total to 990,292 shares.

• Appaloosa: Added 1.45M Nvidia shares, up 483%, bringing total to 1.75M shares.

Both funds also increased stakes in struggling health insurer UnitedHealth Group (guess who else bought these?), whose shares jumped 8.2% after hours but remain down 46.3% year-to-date.

Nvidia shares slipped 0.2% after hours Thursday but are up 35.5% YTD.
