Public companies added 30,000 BTC in December 2025, worth approximately $2.6 billion at month-end prices.
This marks an uptrend in monthly Bitcoin purchases, outpacing October and November combined. It also brings public companies’ additions in Q4 2025 above 52,000 BTC, surpassing our projection that treasuries would add 40,000 BTC this quarter.
We observe that December buying was driven almost entirely by Michael Saylor’s Strategy, which bought 22,600 BTC in December. This marks Strategy’s biggest buying month since July, bringing the company’s total holdings to 672,497 BTC, and accounting for 75% of all companies’ December additions (or 78% of net additions after sales).
Other major additions in December include:
Metaplanet’s purchase of 4,279 BTC, raising its holdings to 35,102 BTC — just 8,400 BTC less than the third-largest public treasury, XXI
American Bitcoin’s addition of 1,094 BTC, bringing its holdings to 5,098 BTC and reporting a BTC Yield of 96.5% since its September Nasdaq listing
Cango and Bitfarms’ 516.9 BTC and 425 BTC, added through mining activity
