Gumi is getting serious about crypto. The Japanese game developer just teamed up with SBI Financial Services to launch a ¥3 billion crypto asset fund, with operations kicking off August 1.
The fund, called SBI Crypto Fund I, is a private placement vehicle structured as a Japanese silent partnership. SBI Financial Services holds 51% ownership, while Gumi’s subsidiary gC Labs takes the remaining 49%. Daiwa Securities Group is also in, along with other investors whose names and contribution amounts weren’t disclosed. SBI Crypto Fund LLC will manage day-to-day operations. The planned run is three years, and the fund’s capital sits at roughly ¥3 billion — no details on whether more can be added after launch.
Not a small bet.
The fund targets Bitcoin and major listed altcoins, though Gumi didn’t name which altcoins specifically. Strategies will include staking, portfolio rebalancing, and hedging. Custodial arrangements, fee structure, and risk management details weren’t shared either. Gumi was careful to note the announcement isn’t a promise of returns or an invitation to invest — pretty standard legal cover for a private placement, but worth flagging.
A Launch That Was Already Delayed Once
The fund was originally supposed to go live in 2025. It didn’t. Gumi and SBI pushed the start date back to get a clearer read on crypto market conditions, which, fair enough — the past couple of years have been wild for digital assets globally. Launching into a volatile market without a solid baseline would’ve been a rough start for any fund trying to build a credible track record.
Now they’re moving. And the timing matters, because Japan’s regulatory environment has been shifting. The country’s Financial Services Agency has been looking at potential rule changes that could eventually allow crypto exchange-traded funds. A Bitcoin ETF in Japan could potentially happen by 2028, though that’s speculative — no firm timeline exists. Still, funds like SBI Crypto Fund I are probably positioning themselves to feed data into whatever regulatory framework emerges. The whole point, per Gumi, is to gather performance data on portfolios that blend traditional and digital assets. That data could inform future investment trusts down the line, though no retail products have been approved or announced.
Gumi’s Crypto Balance Sheet Is Already Big
Here’s the context that makes this fund launch more than just a press release: Gumi already holds a massive crypto position. As of April 30, 2026, the company held ¥14.13 billion in crypto assets — up 86% from the year before. That’s not a side hustle. That’s a core part of the balance sheet.
Crypto valuation gains hit ¥2.63 billion, which basically carried Gumi’s ¥2.17 billion ordinary profit for the period. Operating profit dropped to ¥83.3 million, and the company actually recorded a ¥60.4 million loss from crypto sales. So the gains weren’t from trading — they came from holding. Valuation, not velocity.
Gumi’s crypto activities go beyond just holding Bitcoin. The company manages XRP holdings and uses Hinode Technologies for portfolio management. It had previously received approval for a ¥1 billion Bitcoin purchase, and XRP has been adopted as a corporate treasury asset. That’s a pretty deliberate, multi-asset approach — not a company that stumbled into crypto.
The fund structure with SBI is an extension of that thinking. By partnering with SBI Financial Services, a heavyweight in Japanese financial services, Gumi gets institutional credibility and operational infrastructure. SBI brings the financial services muscle; gC Labs brings the crypto-native experience. Whether that split actually produces better returns than a straight index approach remains to be seen — the fund hasn’t disclosed return targets.
What’s Still Unclear
Quite a bit, honestly. No reporting schedule was included in the announcement. No specific altcoin names. No custodial setup. No fee breakdown. No word on whether outside capital can join after August 1.
Staking strategies add another layer of complexity — staking returns vary significantly by asset and validator, and those details matter for anyone trying to model performance. Hedging strategies weren’t explained either, so it’s unclear how much downside protection the fund is actually building in.
Future disclosures from Gumi, SBI, or SBI Crypto Fund LLC will be needed to fill those gaps. Right now, investors and observers are working with a fairly thin disclosure. The fund is private, which means transparency obligations are limited compared to a public vehicle.
Gumi’s crypto assets stood at ¥14.13 billion as of April 30, 2026.
