Sui Gains Public Market Access as Grayscale’s GSUI Lists on OTCQX

Grayscale, the world’s largest digital asset–focused investment platform, announced today that its Grayscale® Sui Trust has begun trading on OTCQX®, the premier secondary U.S. market operated by OTC Markets Group Inc., under the ticker symbol GSUI. The move opens a new avenue for investors who want exposure to Sui, a Layer 1 blockchain built to simplify smart-contract creation and deployment.

Sui is designed as a developer-first network that emphasizes transaction speed, scalability, and a user experience intended to support mass adoption. Grayscale says the Trust provides investors a way to participate in that vision without directly managing on-chain assets. The trust has been available by private placement to eligible accredited investors since August 2024; its public quotation represents a deliberate step in Grayscale’s broader plan to migrate private products into public markets and, eventually, exchange-traded products.

Bringing Sui Exposure to Public Markets

“GSUI’s public quotation reflects Grayscale’s effort to offer investors more ways to participate in the growing crypto ecosystem,” said Rayhaneh Sharif-Askary, Head of Product & Research at Grayscale. She added that Sui’s focus on speed, scalability and user experience is the kind of innovation the firm looks to champion, bringing investors exposure to technologies reshaping the digital economy.

Adeniyi Abiodun, Co-Founder and CPO at Mysten Labs, one of the original contributors to Sui, welcomed the news, saying the network was built to power the next generation of the internet: fast, resilient and intuitive enough for billions of users. “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,” Abiodun said.

Since its founding in 2013, Grayscale has positioned itself as a go-to platform for investors, advisors and allocators seeking single-asset, diversified and thematic exposure to digital assets. The company frames the GSUI listing as part of a decade-long effort to broaden investor access to next-generation blockchain protocols while leveraging its experience as a dedicated digital-asset investment manager.

The Trust’s arrival on OTCQX makes exposure to Sui more accessible to a wider set of market participants and highlights the continuing trend of crypto products moving from private placements and specialized vehicles toward more mainstream public-market formats. For investors watching the evolution of Layer 1 blockchains, GSUI now offers a publicly quoted option to gain indirect exposure to Sui’s potential growth.
