Grayscale Taps Coinbase for Proposed Sui ETF

Grayscale Investments, a leading digital asset manager, formally submitted a proposal on February 14, 2026, to launch an exchange-traded fund (ETF) based on the Sui blockchain's native SUI token. The regulatory filing designates Coinbase Custody as the custodian for the fund's underlying assets. This partnership aligns a premier asset manager with a trusted, regulated custodian, creating a framework designed to meet the rigorous security and compliance standards of institutional investors.

Filing Signals Deepening Institutional Trust in Sui

The move provides a strong signal of Wall Street's growing recognition of the Sui blockchain. By pursuing an ETF, Grayscale is working to create a regulated and accessible investment vehicle that would allow a broader range of investors, from institutions to retail participants, to gain exposure to Sui without directly holding the cryptocurrency. Approval of the ETF could unlock significant capital inflows, enhance market liquidity for the SUI token, and solidify the blockchain's position as a credible platform for decentralized application development.
