Jane Street’s disclosures signaled a major breakthrough for the cryptocurrency mining sector and caused shares in several notable Bitcoin mining firms to surge dramatically, reflecting institutional trust and building within this industry.
Jane Street’s Strategic Investments.
Jane Street disclosed its holdings in three major Bitcoin mining companies on October 23, 2025: Cipher Mining (NASDAQ: CIFR), Bitfarms (NASDAQ: BITF), and Hut 8 Mining (NASDAQ: HUT). They reported 5% stakes in each: 19 million shares at Cipher Mining; 5.4% stake in Bitfarms totalling 29.9 million; and an approximate 5.5% position at Hut 8. These positions were disclosed through Schedule 13G filings with the U.S. Securities and Exchange Commission to demonstrate their passive ownership rather than activist involvement; for each company there were multiple filings under.
The Chronicle-Journal reported on these positions indicating passive ownership rather than activist involvement by providing additional news updates as they occured.

Following public disclosure of these positions, affected stocks experienced dramatic gains. Cipher Mining saw its share price surge 12.7% to $19.44; Bitfarms gained 12.5% to $4.69 and Hut 8 gained 8.6% – all significant increases for any stock in any given day! Hut 8 also advanced 8.6% toward its goal price. Across the Bitcoin mining sector as a whole, there was positive movement; for instance Iris Energy (NASDAQ: IREN), HIVE Blockchain Technologies (NASDAQ: HIVE), and Applied Digital Corporation (NASDAQ: APD) recorded increases over 6% – which TheMinerMag reported on.
