9. Hut8

Canadian Bitcoin mining firm Hut 8 holds 13,696 BTC, worth over $1 billion at current prices according to its last BTC-denominated update.

In June 2021, the company was listed on the Nasdaq Global Select Market under the HUT ticker, with the company's SEC filing noting that it's "committed to growing shareholder value by increasing the number and value of our Bitcoin holdings." In November 2023, the firm merged with fellow mining company US Bitcoin, with the post-merger firm billing itself as an “energy infrastructure company targeting Bitcoin mining and data centers.”
