SBI VC Trade Partners with WIZE for Solana Trading and Custody

SBI VC Trade, the crypto exchange subsidiary of SBI Holdings, announced a partnership with WIZE (formerly Mobcast Holdings, TSE: 3664) on June 4, 2026, to provide Solana (SOL) trading, custody, and staking support. The collaboration targets large clients via the SBIVC for Prime service, aiming to bolster WIZE’s Solana Treasury Business.

WIZE launched its Solana Treasury Business in 2025 as a next-generation growth strategy. The initiative seeks to maximize shareholder value and meet listing requirements on the Tokyo Growth Market, while potentially integrating with the company’s core Social Entertainment & Media business. By leveraging SOL, WIZE hopes to create a virtuous cycle of social contribution and sustainable corporate growth.

SBI VC Trade will offer three key advantages under the partnership:

• SBI Group Safety: As part of the TSE Prime-listed SBI Holdings, the exchange operates under strict Japanese regulatory frameworks, including licenses for crypto exchange and Type I financial instruments business.
• Flexible Purchase Options for Large Trades: Through the global market maker B2C2, SBI VC provides over-the-counter (OTC) trading with special spreads and "SBI Crypto Options," allowing clients to target specific SOL prices while securing premium cash payments.
• Dedicated Account Support: A licensed sales representative from the Japan Virtual Currency Exchange Association (JVCEA) will assist corporate clients via face-to-face or online consultations.

WIZE, which focuses on lifestyle and digital IP as well as IP investment, uses its acquired SOL for validator operations and staking to drive long-term asset value appreciation. The partnership with SBI VC Trade aims to strengthen these treasury operations.

The move underscores SBI Group’s broader strategy to expand institutional crypto services under its "Crypto Assets also SBI" slogan, targeting full-line offerings beyond simple trading.
