Try Dealroom → Securities, following its acquisition by Bitcoin-focused investment firm Metaplanet. The rebranding is subject to shareholder approval at a meeting on 13 July 2026.

The terms: Metaplanet acquired a 100% stake in Siiibo Securities for 2.1 billion yen, about $13 million. The deal was announced in June 2026.

What's the endgame? Metaplanet wants to build what it calls a "BTC x Finance" platform. The rebranded brokerage will offer Bitcoin-based financial products to retail investors in Japan, though specific products have not been disclosed.

Why now? The move fits Metaplanet's strategy of accumulating Bitcoin as a primary treasury asset, an approach compared to MicroStrategy's in the US. It also reflects a wider trend of publicly traded Asian companies adopting Bitcoin-centred treasury strategies.

What could go wrong? Any new products must comply with Japan's securities and payment services laws. The Financial Services Agency oversees crypto exchanges and related services in the country.

The signal: If approved, Metaplanet Securities would be one of the few licensed brokerages in Japan pivoting explicitly toward Bitcoin-focused retail products — a sign of growing convergence between traditional brokerages and digital asset platforms.
