Grayscale Sui Trust GSUI Debuts on OTCQX, Opening Regulated Access to SUI Tokens

Grayscale Investments announced that its Grayscale® Sui Trust (GSUI) began trading on the OTCQX® Best Market on November 20, 2025, marking a significant step in broadening investor access to the SUI token. The trust allows U.S. investors to gain exposure to SUI—the native token of the Sui blockchain—through traditional brokerage accounts, eliminating the need for direct cryptocurrency management.

This development enables seamless participation in the SUI ecosystem, as shares of GSUI can be bought and sold like any other security, providing a regulated alternative to crypto exchanges. Rayhaneh Sharif-Askary, Head of Product & Research at Grayscale, emphasized that "GSUI’s public quotation reflects Grayscale’s effort to offer investors more ways to participate in the growing crypto ecosystem."

Grayscale plans to convert GSUI into an Exchange Traded Product (ETP) once it meets the SEC’s Generic Listing Standards for Commodity-Based Trusts, a move that could enhance liquidity and accessibility. Adeniyi Abiodun, Co-Founder and CPO at Mysten Labs, highlighted the broader impact: "Through Grayscale, more investors and institutions can now take part in that vision, supporting the continued growth of Sui’s technology and the ecosystem around it."

The OTCQX listing, known for its transparency and regulatory rigor, underscores Grayscale’s strategy to expand crypto-based products, leveraging Sui’s focus on scalability and fast transactions for decentralized applications.
