% of 13F value is the position's value against the whole disclosed 13F value, so the rows shown here do not sum to 100% unless every position is listed. A Note is a convertible bond, which the filing sizes by its face amount rather than a share count. A Preferred, Unit or Warrant line is that security as the filing names it (depositary preferred shares, units, warrants), not the common stock.

A change is this filing measured against the one before it. Est. amount moved is the shares added or sold, priced at the Jun 30, 2026 close. An estimate: a 13F gives no trade prices or dates. For a sold-out position, its value at the previous quarter end.
Questions
What does Magnetar Capital hold?
Magnetar Capital disclosed 1,134 positions worth $11.0B in the Q2 2026 13F filing. The largest is CRWV at 47.3% of the disclosed value. A 13F lists US-listed stock and options on it; short sales and cash are not in it.
What did Magnetar Capital buy and sell last quarter?
Comparing the Q2 2026 filing with the quarter before, the largest moves were trimming CRWV, selling out of AL, opening a position in D and selling out of PRA. Changes are measured against the previous filing, not against trades, because a 13F does not disclose trades.
How current is this?
This is the Q2 2026 filing, covering positions held on Jun 30, 2026 and filed with the SEC on Aug 14, 2026. A 13F is due 45 days after the quarter ends, so the most recent filing is always at least six weeks behind the market, and the manager may have changed the book since.
