Strategy (formerly MicroStrategy) is making headlines with its 506,137 Bitcoin treasury, worth $43 billion. But many other companies are also including Bitcoin in their financial plans. Here’s a round-up of some major stackers:
GameStop (Video Game Retailer)
GameStop just announced plans to raise $1.3 billion specifically for Bitcoin treasury adoption. GameStop plans to use “convertible notes.” These notes are a mix of debt and stock for institutional investors to buy.
Marathon Digital (Bitcoin Miner)
Marathon Digital Holdings is one of the world’s largest Bitcoin miners. It operates through a network of U.S.-based facilities powered by renewable energy.
Marathon has emerged as the second-largest corporate Bitcoin holder globally, with 46,374 BTC (~$4 billion) as of March 2025. They announced a $2 billion stock offering to buy more Bitcoin and support operations. However, the company risks diluting shareholder value by selling more company stock to fund growth.
Metaplanet (Tokyo Finance Firm)
Metaplanet uses loans and smart trading to buy Bitcoin at a low cost. For example, they sold bonds to buy Bitcoin and used options to get discounts. Metaplanet recently acquired 696 more bitcoin for $67.9 million, raising its total holdings to 4,046 BTC.
Genius Group (Education Tech)
Genius Group has put 90% of their savings into Bitcoin (about 440 Bitcoin worth $42 million). Their Bitcoin stash is worth more than the company’s total market value. They also accept Bitcoin payments for online courses on AI.
Tether (Stablecoin Issuer)
Tether added 8,888 BTC worth $735 million in this year, becoming the sixth-largest Bitcoin holder.
