The U.S. Securities and Exchange Commission (SEC) has approved the 21Shares Spot SUI Exchange-Traded Fund (ETF), which began trading on the Nasdaq exchange under the ticker TSUI on February 24, 2026. This marks a significant milestone, providing U.S. investors with a regulated, high-liquidity vehicle to gain direct exposure to the SUI token through traditional brokerage accounts.
The fund is structured as a spot ETF, meaning each share is backed by physical SUI tokens held in secure custody by Coinbase Custody Trust Company. This offers pure exposure to SUI's spot price without the complexities of direct token ownership or the roll costs associated with futures-based ETFs.
"TSUI marks yet another widely-available access point to Sui, leveraging the industry’s preeminent tech stack to support global payments use cases and financial applications at scale," said Evan Cheng, Co-Founder and CEO of Mysten Labs, the original contributor to Sui. The approval follows 21Shares' earlier launch of a leveraged SUI product in December 2025 and reflects accelerating institutional confidence in the Sui ecosystem.
The launch is seen as a pivotal evolution in the U.S. regulatory posture towards digital assets, following earlier spot Bitcoin ETF approvals. It sets a potential framework for evaluating other crypto assets based on market structure and custody readiness. Analysts project the ETF will significantly increase SUI's liquidity, enhance price discovery, and provide a compliant pathway for major institutional investors like pension funds and asset managers.
