Capital B Buys 376 Bitcoins in Its Biggest Purchase of 2026

European bitcoin treasury Capital B has announced a BTC buy, snapping up 376 coins — one week after it said Blockstream boss Adam Back was investing in the company.

The Euronext Growth-listed company said Tuesday that it now owns 3,521 bitcoins — worth over $277 million at today’s prices — making it the 25th biggest publicly traded bitcoin treasury in the world, according to Bitcoin Treasuries data.

Capital B’s buy was for €25.3 million (over $29 million), according to its announcement.

Just last week, the company said that top bitcoiner Adam Back, who heads up bitcoin infrastructure company Blockstream, had invested €7.6 million ($8.8 million) in Capital B to help with its buys.

The firm in August said it had raised €21 million ($24 million) in a private placement backed by Back and asset manager TOBAM.

The bitcoin treasury’s stock was trading 2% lower on Tuesday.

Capital B built most of its bitcoin position through fundraising rounds during the first half of 2026.

In May, it snapped up 192 coins for €13 million after completing three capital raises.

The company, which calls itself “Europe’s first Bitcoin treasury company,” is trying to build a bigger bitcoin position as other treasuries look to raise funds and accelerate their buys.

Capital B says on its website that it wants to eventually hold 210,000 bitcoins. “Our objective is simple: accumulate 1% of Bitcoin’s total supply by 2033,” it reads.

Digital asset treasuries became big in 2025 as more publicly traded companies tried to follow in the footsteps of Nasdaq-listed Strategy (formerly MicroStrategy), which started buying bitcoin in 2025.

Hundreds of publicly traded companies started buying bitcoin — with many buying other cryptocurrencies — to boost their stock prices. But since the price of bitcoin started dropping, a number of them are now under water or have had to sell their holdings.

Strategy, the largest corporate holder of the asset, has this year slowed down its bitcoin buys and instead pivoted to building a stronger cash balance and buying back its stock as the price of its shares has tumbled.
