Bitaigen Research From the perspective of the Bitaigen editorial team, we have compiled the recent share‑holding disclosures of the major Bitcoin mining corporations and examined the chain reaction these disclosures triggered in their stock prices. The article reveals the passive‑investment logic behind institutional players, helping readers grasp potential trends in the mining sector. We also analyze the market signals that may arise from the trading firm’s stake‑holding strategy, offering investors a more comprehensive viewpoint worth a careful read.
The security and operation of the Bitcoin network depend on mining — the process of using specialized computing equipment to solve complex mathematical problems, confirm transactions, and generate new coins. As the industry scales, a handful of large‑scale mining firms have begun to dominate the overall landscape, and they are projected to deliver significant performance gains before the end of 2025. In fact, over the past twelve months several mining companies have posted stock price increases that outpaced Bitcoin’s own performance. Yahoo Finance data shows that Bitfarms climbed roughly 131 % over the year, while Hut 8 surged about 211 % in the same period; by comparison, Bitcoin’s annual price appreciation was approximately 73 %.
Recently, market attention has swung back to the mining sector because the trading firm Jane Street disclosed in a filing to the U.S. Securities and Exchange Commission that its affiliates collectively own about 5 % of Bitfarms, Cipher Mining and Hut 8. It is important to note that these holdings are passive in nature rather than an active, hands‑on strategy. Following the public release of the filing, the three stocks each jumped between 8 % and 13 % on the same day and continued to climb on Friday.
According to Yahoo Finance’s end‑of‑day data, Bitfarms (ticker BITF) rose 10.68 %, Cipher Mining (ticker CIFR) surged 19.73 %, and Hut 8 (ticker HUT) advanced roughly 17.27 %.

Beyond the three firms mentioned above, other Bitcoin mining equities also posted impressive gains on Friday:
- American Bitcoin Corp. + 11.29 %
- IREN Limited + 12.60 %
- Hive Digital Technologies + 17.77 %
Jane Street, an active proprietary trader and market‑maker in both equities and digital assets, first signaled its interest in Bitcoin mining back in 2023 by taking a position in Marathon Digital (ticker MARA). After Google announced on September 25 that it had acquired a 5.4 % stake in Cipher Mining, Jane Street once again disclosed its holdings in the sector.
In summary, continued interest and capital inflows from institutional investors suggest that the share prices of Bitcoin mining companies still have room for further appreciation.
