Grayscale’s SUI Trust Explodes Onto OTCQX - Institutional Floodgates Swing Wide Open

Wall Street's favorite crypto gateway just kicked down another barrier.

Grayscale's SUI Trust (GSUI) launched trading on the OTCQX market today, giving traditional investors their smoothest path yet to exposure in the Sui ecosystem. No crypto exchanges, no wallet setups - just pure institutional-grade access.

The Mainstream Migration Accelerates

Grayscale continues its relentless expansion of digital asset products, proving yet again that traditional finance can't ignore the crypto revolution. The OTCQX listing represents another strategic bridge between conventional markets and decentralized networks.

SUI joins an elite club of digital assets with dedicated institutional vehicles, signaling growing confidence in the Layer 1's technology and long-term viability. Because nothing says 'serious investment' like putting it in a fancy wrapper that costs 2% annually.

Another brick falls in the wall separating traditional finance from crypto's explosive growth. The institutions are coming - whether they understand the technology or not.

TLDR

• Grayscale Sui Trust GSUI offers exposure to SUI tokens via OTCQX trading.
• Grayscale’s GSUI starts trading on OTCQX, providing SUI token access in U.S. brokerage accounts.
• Grayscale Sui Trust GSUI aims to transition to ETPs once SEC standards are met.
• GSUI trading on OTCQX market reflects Sui’s blockchain scalability and fast transactions.

Grayscale Investments announced that its Grayscale® sui Trust (GSUI) began trading on the OTCQX® Best Market, starting on November 20, 2025. This marks an important milestone for both Grayscale and the Sui blockchain, as the Trust offers investors exposure to SUI, the token associated with the Sui blockchain.

The listing on the OTCQX market provides a platform for easier access to SUI for investors who may not want to directly interact with cryptocurrencies.

The Sui blockchain, designed for high-speed and scalable smart contract creation, underpins the GSUI investment product. Grayscale’s initiative allows investors to gain exposure to SUI tokens in the form of a security without needing to buy, store, or manage the cryptocurrency directly.

Exposure to SUI Token Now Available via Grayscale’s Trust Product

The Grayscale® Sui Trust (GSUI) offers a convenient way for U.S. investors to gain exposure to SUI, the native token of the Sui blockchain. This blockchain is recognized for its focus on scalability, speed, and a developer-friendly environment, making it an attractive platform for decentralized applications and smart contracts.

Previously, the Trust was available only through private placements for accredited investors. With the listing on OTCQX, the trust opens the door for broader participation. Investors can now buy and sell GSUI shares through their regular brokerage accounts, providing a seamless entry into the SUI ecosystem.

As noted by Rayhaneh Sharif-Askary, Head of Product & Research at Grayscale, “GSUI’s public quotation reflects Grayscale’s effort to offer investors more ways to participate in the growing crypto ecosystem.” By offering exposure to Sui, Grayscale is helping to pave the way for future blockchain innovations, allowing institutions and individual investors alike to participate in new digital technologies.

Grayscale’s Strategic Path Toward ETP Conversion for GSUI

Although the GSUI Trust is now listed on OTCQX, Grayscale has stated that the product is not yet fully in compliance with the SEC’s new Generic Listing Standards for Commodity-Based Trusts.

Grayscale plans to convert GSUI into an Exchange Traded Product (ETP) once those regulatory requirements are met, similar to other crypto investment products the company has launched. This transition WOULD allow more streamlined access for investors and could increase the liquidity of GSUI.

“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,” said Adeniyi Abiodun, Co-Founder and CPO at Mysten Labs, the company behind the Sui blockchain.

In time, once the necessary regulatory conditions are fulfilled, the GSUI could transition to an ETP, allowing even greater exposure and easier access for the public.

OTCQX Listing Marks Milestone for Grayscale Sui Trust GSUI

The OTCQX market is known for its streamlined requirements, which are designed to lower costs and complexity for issuers. For investors, it provides a transparent, regulated platform to trade securities.

The high standards set by the OTCQX market ensure that listed companies meet rigorous financial, governance, and compliance criteria, thus offering investors additional confidence in the assets they purchase.

By listing on OTCQX, Grayscale has aligned itself with the standards of a well-regulated U.S. market, offering greater trust to investors who are looking for exposure to emerging technologies like the Sui blockchain. The listing represents an important step forward in Grayscale’s ongoing strategy to expand its crypto-based product offerings to a wider audience.
