Superplanet targets $16B Bitcoin-backed preferred stock market with Metaplanet’s backing

Metaplanet, the Japanese company that has quietly amassed roughly 43,000 BTC, is making its loudest move yet: acquiring a Nasdaq-listed gaming company, renaming it Superplanet, and using it as a launchpad to tap the US preferred stock market with Bitcoin-backed securities. The deal involves 2,100 BTC and $2.5 million in cash flowing into Super League Enterprise (SLE), giving Metaplanet approximately 95.7% ownership of the renamed entity.

The $16 billion figure refers to the existing US Bitcoin-treasury preferred securities market that Superplanet intends to compete in.

How the deal works

The 2,100 BTC being invested, roughly 4.9% of Metaplanet’s total holdings, will sit in a five-year lock-up. That locked Bitcoin serves as collateral for potential future perpetual preferred stock issuances in the US market.

Perpetual preferred stock is a hybrid instrument that sits between debt and equity. Holders get fixed dividend payments like a bond, but the security never matures. For companies, it’s a way to raise capital without diluting common shareholders, which is exactly the pitch Metaplanet is making.

Metaplanet has also secured rights to invest up to an additional $210 million in junior preferred stock over the next 24 months.

Simon Gerovich, Metaplanet’s CEO, will chair Superplanet’s board. The transaction is expected to close in Q4 2026, pending shareholder and regulatory approvals. Super League’s existing gaming and media operations will continue operating under the Superplanet brand.

Why a US listing matters

Metaplanet already ranks as the world’s third-largest corporate Bitcoin holder. The cross-border structure creates a two-exchange presence: Metaplanet trades in Tokyo while Superplanet will trade on Nasdaq. Both hold Bitcoin on their balance sheets, accessing different investor pools with different risk appetites and regulatory frameworks.

The broader corporate Bitcoin treasury trend

The risk calculus is worth examining. If Bitcoin’s price drops significantly during the lock-up period, the collateral backing those preferred securities loses value while the dividend obligations remain. Investors evaluating these instruments will need to price Bitcoin volatility into their yield expectations.

Metaplanet’s 43,000 BTC war chest provides meaningful cushion. The 2,100 BTC committed to this deal represents less than 5% of total holdings. The $210 million option for additional junior preferred stock investment suggests the company views this US beachhead as the beginning of a larger capital markets operation.
