Insider selling has dominated May filings. Three names stand out from the data.
CoreWeave is the biggest story. Investment firm Magnetar Financial has filed over $920 million in sales since May 1. The hedge fund is a 10% owner and has unloaded more than 7 million shares across dozens of trades. CoreWeave only went public in March 2026. Magnetar is moving fast to reduce its position.
LifeStance Health saw $280 million in combined insider sales filed this week. Private equity backer TPG sold $227 million worth of shares on May 12. Director Darren Black filed a $47 million sale on the same date. Both filings hit the SEC on May 14.
Twilio also drew attention. Board-linked hedge fund manager Andrew Stafman filed a $131 million sale on May 12. That's 675,000 shares at roughly $193 each.
One buyer stands out against the selling tide. Bill Gates filed a $35 million purchase in Republic Services, the waste management giant. He bought 173,819 shares on May 13.
Apple Chairman Arthur Levinson filed two sales totalling $71 million. Both trades occurred on May 6.
