Gumi Bets 3 Billion Yen Fund on Japan Crypto ETF Path

Japanese game developer gumi Inc. and SBI Financial Services will begin operating a 3 billion yen (about $18.3 million) private crypto fund on August 1. The vehicle, called SBI Crypto Fund I, will hold Bitcoin and major altcoins while running staking, rebalancing and hedging strategies.

The launch is a concrete three-year bet. Gumi and its largest shareholder want operating data and a corporate-bridge record ready for the moment Japan clears crypto exchange-traded funds, now widely expected in late 2027 or 2028.

Three Billion Yen Goes Live on August 1

SBI Crypto Fund I is structured as a private placement with a three-year term. Multiple institutions, including Daiwa Securities Group, are participating as investors. The operator is SBI Crypto Fund, a joint venture owned 51 percent by SBI Financial Services and 49 percent by gumi subsidiary gC Labs.

Earlier plans targeted a late-2025 start. Managers delayed the launch to watch crypto market conditions more carefully. The fund focuses on listed crypto assets and aims to supply liquidity to Japanese enterprises exploring Web3.

According to gumi’s own earlier disclosure, the target is a multiple on invested capital of 2-6x over the three years by combining DeFi tools with traditional risk controls.

• Size: approximately 3 billion yen ($18.3 million)
• Term: three years
• Start: August 1, 2026
• Core holdings: Bitcoin and major altcoins
• Tools: staking, portfolio rebalancing, hedging

The November 2025 progress notice on the fund already framed the mission as bridging Japanese companies to Web3 innovation while building results ahead of any ETF ban lift.

Gumi’s Own Crypto Holdings Nearly Doubled

The fund sits on top of a balance sheet that already treats crypto as a material asset class. As of April 30, 2026, gumi held 14.13 billion yen in crypto assets, up from 7.58 billion yen a year earlier.

That jump helped the company’s full-year numbers. For the fiscal year ended April 2026, unrealised gains on crypto valuations contributed roughly 2.63 billion yen toward a return to profit, with ordinary profit reaching 2.17 billion yen and net profit 1.45 billion yen on 9.18 billion yen in revenue.

gumi also runs portfolio management services through Hinode Technologies and has been expanding its Neo-Crypto segment alongside its core mobile games business.

The Treasury Is Pivoting Hard to XRP

Inside that 14.13 billion yen pile, strategy has shifted. Management materials for the April 2026 fiscal year said gumi will make XRP its primary crypto holding and aims to become Japan’s largest XRP treasury and management company.

The company plans gradual conversion of existing positions plus possible additional purchases depending on market conditions. It intends to layer covered-call options on the XRP position to generate premium income and dampen some volatility.

SBI’s long-standing ties to the XRP ecosystem, including SBI Ripple Asia and remittance corridors that use XRP as a bridge asset, sit behind the choice. Readers tracking XRP price action and Ripple stablecoin moves will recognise the same institutional bias that has shaped Japanese corporate interest for years.

Japan’s ETF Window Is Opening in Stages

Japan still has no listed crypto ETFs. The Financial Services Agency has been reviewing rules that would reclassify certain crypto assets as financial instruments under the Financial Instruments and Exchange Act. That change would bring insider-trading rules and open the door to ETF structures.

Parliamentary steps in 2026 advanced related legislation that also cuts the top crypto tax rate toward a flat 20 percent. Market timelines cluster around late 2027 or 2028 for the first spot products on the Tokyo Stock Exchange.

gumi’s fund language is explicit: accumulate track record and data now so the group can play a central role once those products become legal. The same logic appears in SBI materials that already discuss crypto-asset ETFs and hybrid gold-crypto investment trusts with partners such as Franklin Templeton.

With the possible lifting of the ban on crypto ETFs in Japan, the Fund will look ahead to the formation of that market, accumulating data and results through actual operations with the aim of establishing itself in a central role as a leading company.

That passage comes from gumi’s own November 2025 notice and remains the clearest statement of intent.

SBI Already Owns Nearly a Third of Gumi

This is not an arm’s-length partnership. SBI Holdings holds roughly 33 percent of gumi (32.98 percent listed in recent group materials) after a capital and business alliance signed in December 2022. The two sides have jointly listed tokens, worked on the OSHI3 project, and now share the crypto fund operator.

SBI’s broader crypto footprint is large. Its crypto-asset business segment has grown sharply, and the group continues to push security tokens, stablecoin experiments, and on-chain products. The SBI group neo-media ecosystem slide deck even places gumi inside a wider entertainment-and-Web3 cluster that funnels customers toward financial services.

In short, the fund lets SBI’s crypto ambitions run through a listed gaming company that already carries significant crypto on its own books.

Staking, Rebalancing and the Data They Want

The investment approach is deliberately multi-tool. Managers will stake eligible assets for yield, rebalance the portfolio as relative values shift, and hedge directional risk. DeFi primitives sit alongside the compliance and security practices of a traditional Japanese financial group.

Legal counsel on SBI Crypto Fund formation confirmed the structure as a listed-crypto-asset vehicle set up as a joint venture, underscoring the regulatory care taken from the start.

For Japanese institutions that still treat direct crypto exposure as operationally heavy, a private fund with staking and hedging already built in offers a cleaner first step. Success over three years would produce exactly the audited performance history an ETF issuer or investment-trust sponsor needs.

Where the Numbers Sit Against Broader Crypto Flows

A 3 billion yen private fund is modest next to global ETF assets. Its value lies in the Japanese regulatory and corporate context. While altcoin season index versus Bitcoin dominance swings and Bitcoin whale buying during dollar strength dominate daily tape, this vehicle is built for a slower, more local cycle: Japan’s corporate treasury awakening and the FSA’s multi-year rule rewrite.

1. June 2025: gumi board resolves to establish the joint listed-crypto fund with SBI.
2. September 2025: SBI Crypto Fund LLC completes specially-permitted services notification with the Kanto Local Finance Bureau.
3. November 2025: public progress notice confirms structure, mission and 2-6x MOIC ambition.
4. July 2026: gumi announces August 1, 2026 start after market-condition delay; Daiwa and others commit capital.
5. 2027-2028 window: expected earliest path for Japanese spot crypto ETFs under revised FIEA treatment.

What Three Years of Operations Buy

By August 2029 the fund will have generated a full three-year audited track record under Japanese rules. That data set can support joint product development with SBI’s asset-management arm, feed into future investment trusts, and position both sides as ready-made partners for any first-wave ETF listings.

Daiwa’s participation adds another major securities name to the investor list, a quiet signal that traditional houses are testing the water through private structures before public products arrive.

gumi keeps running its games business while the Neo-Crypto side compounds. The 14.13 billion yen treasury, now tilting toward XRP, already shows management is willing to put its own capital behind the same thesis the fund sells to outside investors.

The bet is straightforward: Japan’s corporate sector and its regulators are moving. The operators who already hold the data, the compliance muscle and the corporate relationships will write the first products when the gate opens.
