Top 10 Public Companies Holding the Largest Bitcoin Portfolios in 2025

An increasing number of public companies have accumulated Bitcoin in their portfolios, according to BitcoinTreasuries data. As of September 1, 2025, the top 10 companies hold over 860,000 BTC, valued at more than $95 billion, representing 4.7% of the maximum supply of 21 million BTC.

1. Strategy – 632,457 BTC (~$68B)
2. Marathon Digital Holdings – 50,639 BTC (~$5.5B)
3. Twenty One (XXI) – 43,514 BTC (~$4.7B)
4. Bitcoin Standard Treasury Company (BSTR) – 30,021 BTC (~$3.3B)
5. Bullish – 24,000 BTC (~$2.6B)
6. Metaplanet – 20,000 BTC (~$2.1B)
7. Riot Platforms – 19,239 BTC (~$2.09B)
8. Trump Media & Technology Group – 15,000 BTC (~$1.6B)
9. CleanSpark – 12,703 BTC (~$1.4B)
10. Coinbase – 11,776 BTC (~$1.3B)

The fact that other giants—from miners like Marathon Digital to Trump Media and Coinbase—are following the same path shows this is an irreversible trend. Bitcoin is no longer just a technological experiment; it is becoming part of the global corporate economy.

However, risks remain. Excessive BTC concentration in a few company balance sheets can increase volatility, and reliance on funding through equity or debt exposes firms to severe market fluctuations.

Overall, the message is clear: Bitcoin is entering the mainstream, and history may record this as the beginning of a new financial era.
