PRAX is a top-conviction position for Cormorant Asset Management, LP — at 11.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in PRAX belongs to Jupiter Topco LLC, but the position matters far more to Cormorant Asset Management, LP, who has 11.0% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

Top 5 Institutional Movers
PRAX does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
