Fidelity Investments, one of the world's largest asset managers with $4.9 trillion in assets under management, purchased a 7.4% stake in bitcoin mining firm Marathon Digital Holdings (Nasdaq: MARA) for approximately $20 million in July. The investment was distributed across four index funds—FCFMX, FSMAX, FSKAX, and FNCFX—as part of a broader trend of institutional adoption of digital asset exposure.
Fidelity Joins Major Institutional Investors in Marathon
Fidelity's move follows a growing number of traditional finance giants dipping into bitcoin mining. Vanguard Group currently holds about 7.58% of Marathon shares, Susquehanna holds 2.7%, and BlackRock owns 1.59%. The combined institutional ownership underscores the legitimization of bitcoin mining as an investable asset class.
Marathon's July Production Surges 66%
Marathon announced that its July bitcoin production reached 422.2 BTC, up 66% month-over-month, worth over $16 million at current prices. The company now holds approximately 6,225.6 BTC, valued at $236 million. To fuel further growth, Marathon signed an agreement to purchase 30,000 Antminer S19 Pro ASIC miners from Bitmain. Its active fleet of 19,395 miners currently generates about 2 exahashes per second (EH/s) of hashrate.
The combination of institutional backing and aggressive hardware expansion positions Marathon to capitalize on the ongoing bitcoin network growth. Fidelity's entry into the mining sector signals that major capital allocators view bitcoin mining as a strategic exposure to the cryptocurrency ecosystem.
