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.
