Grayscale Sui Trust ($GSUI) Starts Trading OTCQX

Grayscale has officially launched public trading for its Sui-focused investment vehicle, the Grayscale Sui Trust (GSUI), now available on the OTCQX over-the-counter market. The announcement was shared on the company’s social channels and marks a new entry point for investors looking for regulated exposure to the Sui ecosystem.

The Grayscale Sui Trust allows traditional investors to gain exposure to SUI, the native asset of the Sui Network, through a familiar brokerage account rather than directly purchasing or custodying tokens.

According to Grayscale, shares of the trust are designed to reflect the market value of SUI, minus fees and expenses. It’s important to note that the product has historically traded at both premiums and discounts relative to its net asset value.

Mysten Labs: “More Institutions Can Join the Sui Vision”

In the announcement post, Eman Abio, Co-Founder and Chief Product Officer at Mysten Labs, welcomed the development, saying it gives investors and institutions another way to participate in Sui’s mission to power “the next generation of the internet, fast, resilient, and intuitive enough for billions of users.”

The listing broadens access for those who want exposure to Sui’s technology but prefer to invest through regulated securities.

Key Product Details

As of November 21, 2025, the Grayscale Sui Trust reports:

• AUM: $4.23 million
  
• NAV per share: $19.89
  
• Shares outstanding: 212,900
  
• SUI per share: 14.51
  
• Expense ratio: 2.50%

Eligible shares trade under the ticker GSUI on OTCQX and can be bought or sold through most mainstream brokerage platforms.

Risks and Performance Notes

Grayscale cautions that GSUI is a speculative product, and investors could lose their entire investment. The Trust has also not consistently met its investment objective, with NAV performance seeing notable swings year-to-date and since inception.

Since the trust does not operate a redemption program, shares can trade significantly above or below the value of the underlying SUI held in custody.

Why This Matters for the Sui Ecosystem

Sui has built a reputation as a high-performance Layer 1 designed for scalable applications and rapid transaction processing. The trust’s OTCQX listing gives traditional market participants a regulated, simpler path to gain exposure to the network’s growth.

For the Sui ecosystem, this represents:

• Greater institutional visibility
  
• More liquidity pathways
  
• Broader participation beyond crypto-native users

What is the Outlook? 

With GSUI now trading publicly, Sui joins a growing list of digital assets that have dedicated Grayscale products.

While performance volatility and premium/discount dynamics remain, the listing signals deeper market infrastructure forming around Sui, and adds another bridge between traditional capital and emerging Web3 networks.
