Capital B Makes Biggest Bitcoin Buy Since 2025, Boosting Treasury

Paris-listed bitcoin treasury firm Capital B has made its largest individual buy in over a year, acquiring 376 BTC for $29.4 million on Monday.

The purchase was funded by two financings closed the same day, one of which was a private placement of shares with warrants raising €28.7 million at a price of 0.58 euros per share.

Blockstream's chief Adam Back fully subscribed to a €7.6 million tranche that was completed September 2 and also invested in an earlier €21 million block that closed August 28, elevating his stake in ordinary shares to 17.64%.

The acquisition boosts Capital B's treasury to 3,521 BTC purchased for a total of €309.4 million at an average price of €87,878 per coin, well above the $79,000 Bitcoin was trading for Monday.
