Metaplanet Overtakes Riot Platforms to Become 6th Largest Corporate Bitcoin Holder

HKAN | Sep 1

 

Metaplanet, often dubbed “Japan’s MicroStrategy”, has officially surpassed U.S.-based Bitcoin mining giant Riot Platforms (NASDAQ: RIOT) to become the 6th largest corporate holder of Bitcoin, according to new data from Bitcoin Treasuries.

The Tokyo-based investment firm, which has aggressively accumulated Bitcoin throughout 2024 and 2025, now holds more BTC on its balance sheet than Riot Platforms, signaling a growing shift in corporate Bitcoin adoption outside the United States.

Metaplanet first gained attention earlier this year when it announced a bold strategy to make Bitcoin its primary treasury reserve asset, drawing comparisons to MicroStrategy’s Michael Saylor. Its rapid accumulation reflects both institutional confidence in Bitcoin’s long-term role as “digital gold” and Japan’s rising presence in the global crypto economy.

Meanwhile, Riot Platforms remains one of the largest publicly traded Bitcoin mining companies in the U.S., but its holdings have now been eclipsed by Metaplanet’s aggressive accumulation strategy.

Industry analysts say the milestone further demonstrates how global corporations are racing to position themselves in Bitcoin markets, especially amid growing anticipation of favorable regulations and potential monetary shifts worldwide.
