Bitcoin Miners Had a $2 Billion Ghost Seller, Citadel Just Cleared It

Bitcoin miner stocks have spent three weeks trading with a seller sitting on top of them. On Friday, Ken Griffin said that seller is nearly finished.

Griffin told Citadel clients the firm has unwound more than 80% of the risk it absorbed from Leopold Aschenbrenner’s Situational Awareness portfolio. The filings behind that book show miner bets that grew in dollars while shrinking to under 10% of the portfolio.

The fund was buying miners fast and memory chips faster. The Seller Nobody Was Watching Situational Awareness is the artificial intelligence (AI) fund run by former OpenAI researcher Aschenbrenner. It gained 439% in the first half of 2026. Then July arrived.

Leveraged four to one, the fund lost 67% in a single month and handed roughly $10 billion of stock to Citadel on July 30, as BeInCrypto reported when it lost its stock book. Its last filing before that sale is the one that matters.
