According to regulatory filings, Jane Street Group disclosed passive stakes in several public bitcoin miners on Oct. 23 and Oct. 24, 2025, sending a ripple through mining stocks. Reports have disclosed holdings of about 5.4% in Bitfarms Ltd., 5.0% in Cipher Mining Inc., and 5.0% in Hut 8 Corp, all shown on Schedule 13G forms that signal non-activist positions.

Jane Street Discloses Stakes

The filings list Jane Street as a passive investor rather than an activist owner. Based on reports , the group’s move is being read as a vote of confidence in the miners as public companies, not necessarily a plan to run them. The exact dollar value of the stakes was not in the filing summaries made public, but the percentage holdings were clear.
