Twenty One Capital Quietly Amasses $5.1B in Bitcoin Holdings

July 29 2025, Bloomberg reported that Twenty One Capital’s BTC reserves have surged to over 43,500 coins, exceeding initial estimates as institutional treasury accumulation accelerates.

A Bigger Bitcoin Treasury Than Expected

Twenty One Capital has officially surpassed its initial BTC target. According to Bloomberg, the firm now controls over 43,500 Bitcoin about 1,500 BTC more than previously projected thanks in part to a new 5,800 BTC transfer from Tether. That puts its total holdings at an estimated $5.13 billion.

The Bitcoin treasury firm launched in April 2025 with the goal of becoming a top institutional holder. It was founded with support from major players, including Tether, Bitfinex, and SoftBank, and is reportedly preparing to go public via a merger with Cantor Equity Partners.

Bitcoin Accumulation Race Heats Up

Twenty One Capital’s accumulation adds to a growing list of institutions expanding their crypto treasuries. These strategies pioneered by Strategy and Michael Saylor are being adopted by firms seeking long-term Bitcoin exposure without relying on debt.

Notably, Twenty One’s 43,500 BTC puts it close to Bitcoin mining giant MARA Holdings (50,000 BTC) and ahead of many public companies already listed on BitcoinTreasuries.net.

The company is led by Strike CEO and Bitcoin advocate Jack Mallers, further underlining its Bitcoin-native approach.
