JPMorgan’s recent SEC filing shows a 22% drop in the value of its Bitmine shares since September, reflecting volatility despite the company’s dominant Ethereum reserve position.
JPMorgan’s latest SEC disclosure indicates it held 1,974,144 shares of Bitmine Immersion Technologies worth $102 million as of September 30, 2025. The stake’s value has since declined by 22% to approximately $79.41 million. Bitmine, which shifted from Bitcoin mining to focusing on Ethereum reserves in 2025, remains the largest Ethereum holder globally with over 3.24 million ETH.
