European publicly traded companies are competing to expand their Bitcoin treasuries. In August 2026, Sweden-listed H100 Group tripled its holdings to 3,506 BTC through an all-stock acquisition of Norwegian firms Moonshot AS and PDI AS. This transaction, described as a landmark “Bitcoin-for-Bitcoin” M&A deal, briefly positioned H100 Group as Europe’s second-largest public Bitcoin treasury firm.

By September 2026, French-listed Capital B acquired an additional 376 BTC, bringing its total holdings to 3,521 BTC. This acquisition, funded through capital raises supported by investors including Adam Back, allowed Capital B to overtake H100 Group to become the second-largest publicly traded Bitcoin holder in Europe, trailing only Germany’s Bitcoin Group SE.
