The world’s largest hedge funds, including Bridgewater Associates and Tiger Global Management, sharply increased their exposure to Big Tech in Q2, reversing earlier caution and doubling down on the AI-driven market rally, 13F filings show, according to a report by Reuters.

Bridgewater boosted its Nvidia holdings by 154% to 7.23m shares ($1.14bn) – its single largest equity position – alongside significant increases in Alphabet (+84%) and Microsoft (+112%). The macro fund also added to AI-adjacent plays Broadcom and Palo Alto Networks.

Tiger Global meanwhile, ramped up its bets on Amazon (+4m shares to $2.34bn) and added to positions in Nvidia, Microsoft, Meta, and Lam Research, while Discovery Capital took new exposure to Nvidia-backed CoreWeave and doubled its Meta stake. Coatue Management initiated sizeable positions in Arm Holdings ($750m) and Oracle ($843m), while also adding $2.9bn to its CoreWeave investment.

The pivot marks a return to momentum trades after a spring sell-off in the “Magnificent Seven” triggered by tariff volatility and inflation fears.
