Capital B, the Euronext Growth-listed company that bills itself as Europe’s first bitcoin treasury company, has raised €21 million ($24 million) in a private placement backed by Blockstream’s Adam Back and asset manager TOBAM — money it says could buy 270 more bitcoin and push its stack to roughly 3,415 BTC.

The company said Friday that a total of 36,219,070 shares were sold at €0.58 each as part of the deal, a 6.45% discount to Wednesday’s closing price.

Capital B said the net proceeds are expected to reach about €19.9 million after fees and transaction costs.

Capital B is the 27th biggest publicly traded bitcoin treasury in the world, according to Bitcoin Treasuries, with a total of 3,145 bitcoins in its stash — worth $245 million at today’s bitcoin price of $77,960. 

Capital B, which describes itself as Europe’s first bitcoin treasury, built much of that position through fundraising rounds during the first half of 2026. 

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

Capital B’s announcement as other treasuries look to raise funds and accelerate their buys. Just this week, NYSE-listed AI-powered education company Genius Group said it was aiming to build parallel AI and bitcoin treasuries worth a combined $1.6 billion, after the company sold its entire bitcoin reserves to repay $8.5 million in debt. 

Bitcoin treasuries have faced headwinds since 2025 when the price of the leading cryptocurrency took a hit. A number of companies in the space have had to liquidate their holdings, including the biggest corporate holder of bitcoin, Nasdaq-listed Strategy.
