SBI VC Trade, the cryptocurrency subsidiary of Ripple-backed SBI Holdings, has secured a mandate to manage the Solana treasury operations for Tokyo-listed firm WIZE. The agreement, announced on June 5, 2026, places the Japanese financial services giant in charge of the trading, custody, and storage of WIZE’s digital assets.
WIZE, formerly known as Mobcast Holdings, selected the firm after evaluating service providers on regulatory compliance and institutional support capabilities.
The deal reflects a pivot for WIZE, which launched its dedicated Solana Treasury Business in October 2025. By moving its assets to the SBIVC for Prime platform, the company intends to formalize its treasury management while optimizing new revenue streams from its company-operated validator node. Management confirmed that SBI VC Trade will provide Web3-related support and institutional-grade transaction execution for these large-scale holdings.
WIZE currently ranks 15th globally among corporate holders of Solana (SOL) according to data from CoinGecko. This push for professional custody highlights a growing trend among Japanese corporations seeking to secure their digital asset balance sheets through established financial regulated entities. The partners indicated that the move will help WIZE navigate the market as it continues to expand its allocation toward the Solana network.
Solana treasury holdings surpass 32,100 SOL
Specific data released as part of the treasury transition details the scale of WIZE’s commitment to the ecosystem. As of May 27, 2026, WIZE’s total direct SOL holdings surpassed 32,100 SOL. These assets carried a cumulative acquisition value of approximately ¥600 million (roughly $3.8 million) at that time, marking a steady increase in the company’s direct exposure.
Earlier reports from the second quarter of 2026 show the aggressive pace of this accumulation. On April 10, 2026, direct holdings for the WIZE Treasury Core exceeded 24,597 SOL. By April 14, 2026, those same 24,597 SOL were valued at approximately $3.13 million, with an average acquisition price of $127 per token.
This active management has since seen the average purchase price for direct holdings improve to ¥18,672 per SOL as of May 27, 2026.
Beyond direct holdings, the total treasury scale is significantly larger. WIZE’s total treasury, which includes external delegations, reached approximately 152,000 SOL as of April 13, 2026. To support this growth, the firm increased its capital allocation for the Solana Treasury Business to ¥750 million ($4.7 million), up from the initial ¥550 million.
This institutional shift occurs even as altcoin bearish pressure creates volatility in the broader market.
Validator nodes and staking rewards strategy
A central component of the WIZE treasury strategy involves generating passive income through network participation. The firm operates its own validator node on the Solana blockchain, which produces staking rewards and income from transaction processing. SBI VC Trade will now oversee the management of these technical yield-bearing operations through its institutional platform.
Tomohiko Kondo, CEO of SBI VC Trade, noted that his company was the first in Japan to obtain the Electronic Payment Instrument Exchange Service Provider License. This regulatory standing was critical for WIZE’s selection process. The partnership ensures that the income generated from the validator node remains compliant with evolving Japanese financial regulations while utilizing secure, segregated storage solutions.
SBI Holdings CEO doubles down on Ripple partnership
The deal further cements the influence of SBI Holdings within the Japanese crypto sector. The conglomerate has been a partner of Ripple since 2016 and remains its largest external shareholder with an approximate 9% stake. SBI Holdings CEO Yoshitaka Kitao has long been a vocal advocate for the fintech firm, having invested during its Series B funding round that raised $55 million.
Yoshitaka Kitao recently shared a long-term vision for the relationship in an official video. He stated that he plans to invest up to $1.25 billion in a potential Ripple IPO. Kitao clarified this investment would involve pouring in between ¥100 billion and ¥200 billion all at once to “fully complete everything.” He predicted that Ripple will likely go public within the next 12 years.
This deep institutional backing provides a layer of stability for corporate clients like WIZE. As XRP liquidity surges and institutional frameworks mature, SBI continues to leverage its early positioning to attract Tokyo-listed firms. The move from self-custody to a regulated prime brokerage model is becoming a standard requirement for Japanese listed entities holding crypto assets.
Market implications for corporate digital asset treasuries
The decision by a Tokyo-listed firm to hand over treasury control to SBI VC Trade may serve as a template for other mid-cap companies. Professional management reduces the operational risks associated with holding large volumes of SOL in-house. It also provides a clear audit trail for shareholders who are increasingly cautious about the security of digital asset reserves.
As the utility window for digital assets narrows toward regulated use cases, partnerships like the one between SBI and WIZE emphasize the importance of compliance. SBI VC Trade’s role as the custodian for a top global corporate SOL holder positions them as a dominant player in the Asian institutional market.
For Solana, the influx of corporate validators and professional treasury management suggests a hardware-and-capital-intensive phase of network growth.
The collaboration highlights a maturing ecosystem where the focus has shifted from price speculation to yield and security. WIZE’s improved average acquisition price and expanded treasury allocation suggest a long-term commitment to the network’s infrastructure rather than short-term trading. With SBI VC Trade providing the institutional backbone, more Japanese firms are expected to integrate digital assets into their formal financial strategies.
