Capital B, formerly known as The Blockchain Group, has reached the ninth position in daily trading volume relative to market capitalization on the Euronext exchange. The company transitioned to a Bitcoin-focused treasury strategy in late 2024, following a model of raising capital to accumulate the asset.
The firm currently holds 3,521 BTC. Its latest acquisition on September 7, 2026, involved 376 BTC for approximately €25.3 million. The total cost basis for its holdings is roughly €309.4 million, supported by capital raises between €280 million and €300 million. The company aims to eventually accumulate 1% of the total Bitcoin supply, or 210,000 BTC.
On August 5, 2026, Capital B secured a secondary listing on Cboe Europe, which resulted in a doubling of its overall trading activity. Following this, on September 8, 2026, the company performed a 10-for-1 reverse stock split to raise its share price above €5, aiming to attract institutional investors with minimum price requirements.
The company maintains operations in data intelligence, artificial intelligence, and decentralized technology services alongside its treasury activities. Strategic backers include French asset manager TOBAM and Blockstream CEO Adam Back. The firm utilizes the BTC Yield metric to monitor the effectiveness of its share issuance in increasing Bitcoin holdings per share.
