CoreWeave executives have offloaded more than $1 billion in stock since August, joining the ranks of the biggest insider sellers in a quarter defined by AI-fueled profit-taking.

According to Washington Service data, CoreWeave board member Jack Cogen and co-founder Brannin McBee sold nearly $900 million worth of shares after the company’s post-IPO lockup expired in mid-August. The firm’s top institutional backer, Magnetar Financial, also liquidated $1.9 billion worth of shares in Q3—though it still holds over 20% of the company.

The sales follow CoreWeave’s 250% surge since its March IPO, which minted four employee billionaires and became one of Wall Street’s defining AI success stories of 2025.

Inside CoreWeave’s Billion-Dollar Cash-Out

  • Jack Cogen sold 5.1 million shares worth $477 million, under a trading plan established in May.
  • Brannin McBee, who co-founded the company in 2017, sold 4 million shares for $426 million, about 14% of his stake.
  • Both executives capitalized on CoreWeave’s rapid valuation jump—now one of the fastest in recent tech history.

McBee, now valued at $3.9 billion, continues to serve as Chief Development Officer after transitioning from strategy last year.

AI Executives Lead the Great Q3 Sell-Off

CoreWeave’s insider sales are part of a broader AI cash-out wave, with seven of the ten largest sellers last quarter coming from the sector.

  • Jeff Bezos topped the list, unloading $5.7 billion in Amazon shares, his biggest sale since 2020.
  • Arista Networks CEO Jayshree Ullal sold $861 million worth of stock, bringing her 2025 total above 7.5 million shares.
  • Nvidia’s Jensen Huang offloaded 4.3 million shares, worth $743 million, as part of a pre-set plan that could net him nearly $1 billion by year-end.
  • Snowflake’s Frank Slootman, Ares’ Tony Ressler, and Coinbase’s Brian Armstrong each sold hundreds of millions in equity as valuations across the AI ecosystem reached record highs.

AI Boom, Insider Reality

CoreWeave insiders and early investors have collectively cashed out more than $3 billion since the company’s IPO, marking one of the largest early liquidity waves of the AI cycle.

The spree underscores a growing theme on Wall Street: AI valuations have created unprecedented paper wealth—and equally rapid exits.

Analysts warn the pace of insider selling across AI-linked firms could hint at overheating in the sector, even as institutional demand for computing infrastructure remains robust.
