Every quarter, hedge fund watchers comb through Form 13F filings looking for clues about what the smart money is doing next. These filings, covering the quarter ending 2026-03-31, offer a snapshot of new positions taken by some of the most closely-followed names in the business — Bridgewater Associates, Renaissance Technologies, and Soros Fund Management. It is worth remembering that a 13F only shows where a portfolio stood at quarter-end, not the exact date or price at which any position was opened, so these numbers are a lagging picture rather than a live trade ticket. Below is a ranked look at the new positions disclosed this quarter, ordered from largest to smallest by reported value.
1. Bridgewater Associates, LP — $363,998,848
Bridgewater’s largest newly disclosed position this quarter dwarfs everything else on this list, coming in at nearly $364 million. Ray Dalio’s macro-focused firm has long been tracked for how its positioning reflects broader views on the economic cycle, and a new stake of this size during the quarter ending 2026-03-31 stands out as the single biggest move among the filings reviewed here.
2. Bridgewater Associates, LP — $81,198,983
Bridgewater also opened a second new position worth just over $81 million. Seeing two separate new positions from the same fund in one quarter suggests continued portfolio adjustment, though the 13F alone does not indicate whether these were opened early or late in the three-month window.
3. RENAISSANCE TECHNOLOGIES LLC — $79,123,824
Renaissance Technologies, the quant-driven firm known for its systematic approach, disclosed a new position valued at roughly $79.1 million. Renaissance’s filings are watched closely, though the firm’s model-driven process makes any single new stake harder to interpret as a directional signal compared to more discretionary managers.
4. SOROS FUND MANAGEMENT LLC — $63,866,338
Soros Fund Management’s largest new position this quarter came in at roughly $63.9 million. Soros Fund Management has a long history of being scrutinized for macro and thematic bets, and this new stake adds to that quarter’s list of disclosed additions.
5. RENAISSANCE TECHNOLOGIES LLC — $54,151,632
A second new position from Renaissance Technologies, valued at about $54.2 million, rounds out the middle of this ranking. Multiple new positions from the same quant shop in a single quarter are not unusual given the scale and diversification of its book.
6. SOROS FUND MANAGEMENT LLC — $42,482,880
The smallest new position on this list still belongs to Soros Fund Management, at roughly $42.5 million. Even at the lower end of this ranking, the figure represents a meaningful new commitment disclosed for the quarter ending 2026-03-31.
None of the figures above should be read as a recommendation to buy or sell anything discussed here. Position sizes reported in 13F filings reflect quarter-end values and can change materially before or after the filing becomes public, so this list is best treated as a historical record of disclosed positioning rather than a forward-looking signal.
