Magnetar Financial LLC

Magnetar Financial LLC has filed 1,858 Form 4 transactions across just two companies, and the direction is overwhelmingly one-sided. The fund has recorded $5.97 billion in open-market sales and zero open-market purchases. It has also acquired $15 million in shares through grants or awards, which are compensation events rather than conviction buys. The most recent activity, all in CoreWeave (CRWV), shows 14 sell transactions on August 14, 2026, totaling roughly $14.5 million. Individual sale values on that date ranged from $2,860 to $4.61 million, with several tranches above $3 million. Eleven additional filings for CRWV on September 18, 2026, carried code E, which is not part of the standard purchase, sale, or grant legend and carried a value of zero. The pattern is a sustained sell bias. Magnetar has not reported a single open-market purchase in its recent history, and the only non-sale activity is the $15 million in acquired shares, which are compensation awards and not discretionary buys. The August 14 CRWV sales cluster into 14 separate line items, which suggests a systematic reduction rather than a single liquidation event. The dollar values are uneven, with small sales below $100,000 sitting alongside multi-million dollar blocks. Across the entire filing history, sales outnumber acquisitions by a wide margin, and the recent direction has not changed. The September CRWV filings with zero value and code E are ambiguous, but they do not offset the August sell volume. Magnetar's Form 4 footprint is a record of distribution, not accumulation.
