Holdings over time

Cumulative bitcoin held after each disclosed event. The line steps rather than slopes because treasury positions change on purchase dates, not continuously.

We have one dated figure for gumi so far, shown in the table below, and the table says where it came from. A chart needs at least two dated points, and we would rather show nothing than draw a trend through a single figure. This fills in as the company publishes, or as we backfill its earlier announcements.

About gumi

gumi has made mobile games since 2007, best known for Brave Frontier, and has been closer to crypto than most Japanese publishers for years through node operation and blockchain gaming.

Its bitcoin position is modest and dated: 80.35 coins, worth about $9.84 million when disclosed on 3 October 2025. What makes the allocation worth looking at is what sits beside it. The company also committed roughly $18.3 million to an altcoin fund built around yield, which is a larger bet than the bitcoin one and a materially different risk.

So this is not a treasury company in the Metaplanet sense, and gumi has never described it as one. It is an operating games business running a diversified digital asset book, of which bitcoin is the conservative half.
