Metaplanet has cemented its position as one of the world’s largest corporate holders of Bitcoin, surpassing the 30,000 BTC mark after a string of aggressive purchases.

On Oct. 1, the Tokyo-based firm revealed that it had added 5,268 BTC to its balance sheet at an average price of $116,870, spending roughly $616 million. The transaction came less than 2 weeks after its late-September acquisition of 5,419 BTC, its biggest single buy.

Together, the back-to-back moves pushed Metaplanet’s total holdings to 30,823 BTC, accumulated at an average cost of $107,912.

The latest tally represents a dramatic expansion of the company’s initial vision, which began with a target of 10,000 BTC and later grew to 30,000.

With the milestone already exceeded, Metaplanet now sits above Bitcoin Standard Treasury in the rankings and holds the fourth-largest corporate stash of Bitcoin worldwide.

Doubles revenue forecast

Metaplanet’s aggressive treasury buildup is being matched by growth on the revenue side.

The firm reported that its Bitcoin Income Generation unit brought in ¥2.44 billion (~$16.5 million) in Q3 revenue, a 115.7% increase from the previous quarter.
