Insiders Cash Out $1.5B in May

A wave of large insider sales has hit US-listed stocks this month. The filings paint a clear picture: smart money is taking profits.

The biggest story is CRWV. Magnetar Financial, a 10% owner in CoreWeave, filed to disclose it sold over $920 million in shares between April 30 and May 7. The AI infrastructure firm only went public in March. Magnetar offloaded more than 7.1 million shares. CoreWeave's Chief Accounting Officer Jeff Baker also filed a $4.8M sale on May 15.

At SEI, two large insiders — a board member and a 10% owner — filed combined sales of $290 million in early May. Solaris Energy Infrastructure has been a strong performer. The sales suggest those closest to the company are locking in gains.

TWLO saw a board-affiliated hedge fund file a $130 million sale on May 12. Twilio shares have rallied sharply in 2026.

AAPL Chairman Arthur Levinson filed sales totalling $71 million on May 6 trades. The moves came as Apple shares traded near all-time highs.

On the buy side, Bill Gates filed purchases of $99 million in RSG Republic Services between May 11 and May 13. The waste management giant is a long-held Gates Foundation position. Fresh buying at this scale signals continued confidence.

SANM founder and CEO Jure Sola filed a $27M sale on May 6 trades, joining directors who also sold several million in the same window.
