European bitcoin treasury company Capital B has acquired 376 BTC for €25.3 million, or more than $29 million, in its largest bitcoin purchase of 2026.

The Euronext Growth-listed company said Tuesday that it now holds 3,521 bitcoins, worth more than $277 million at current prices. According to data from Bitcoin Treasuries, that makes Capital B the 25th-largest publicly traded bitcoin treasury in the world.

Capital B also reported a BTC Yield of 2.17% year to date. The company announced the acquisition on X:

The purchase came one week after Capital B said that Adam Back, the head of bitcoin infrastructure company Blockstream, had invested €7.6 million ($8.8 million) in the company to support its bitcoin acquisitions. In August, Capital B said it had raised €21 million ($24 million) in a private placement backed by Back and asset manager TOBAM.

Capital B’s stock was trading 2% lower on Tuesday.

The company accumulated most of its bitcoin holdings through fundraising rounds during the first half of 2026. In May, it acquired 192 BTC for €13 million after completing three capital raises.

Capital B describes itself as “Europe’s first Bitcoin treasury company” and is seeking to increase its bitcoin holdings as other treasury companies raise funds and accelerate their purchases. The company says on its website that it ultimately aims to hold 210,000 bitcoins. “Our objective is simple: accumulate 1% of Bitcoin’s total supply by 2033,” the website states.

Digital asset treasuries grew more prominent in 2025 as publicly traded companies sought to follow Nasdaq-listed Strategy, formerly known as MicroStrategy, which began buying bitcoin in 2025. Hundreds of publicly traded companies subsequently began purchasing bitcoin, while many also bought other cryptocurrencies, in efforts to boost their stock prices.

As bitcoin’s price began to decline, some of those companies found themselves holding assets below their purchase prices or were forced to sell their holdings. Strategy, the largest corporate holder of bitcoin, has slowed its purchases this year and shifted toward building a larger cash balance and buying back its stock as its share price has fallen.
