The race to bring a Sui-based exchange-traded fund (ETF) to the U.S. market has intensified, as 21Shares officially filed a 19b-4 form with the U.S. Securities and Exchange Commission (SEC) on May 23. The filing seeks approval to list the 21Shares Sui Spot ETF on Nasdaq, following the firm’s earlier S-1 registration submitted on April 30.
This move positions 21Shares directly alongside Canary Capital, which is also vying to launch a spot Sui ETF, marking the first time multiple Sui-focused funds are undergoing review in parallel by the SEC.
Key Details of the 21Shares Proposal
The 21Shares filing reveals that Coinbase Custody and BitGo will serve as custodians for the ETF. If approved, this would allow U.S. investors to gain regulated exposure to SUI, the native token of the Sui blockchain, without directly managing wallets or dealing with the complexities of on-chain assets.
While the SEC must respond by January 18, 2026, the agency retains the authority to delay decisions for up to 240 days, meaning final approval could come later next year.
21Shares already operates the 21Shares Sui Staking ETP (ASUI) in Europe, currently trading on Euronext Paris and Amsterdam. That product offers a 1.52% staking yield and manages over $168 million in assets, signaling strong demand for institutional-grade Sui exposure overseas.
A Competitive ETF Landscape
The competition is heating up in the U.S. ETF market. Canary Capital, the first to file for a Sui ETF, registered its trust in Delaware on March 7, followed by an S-1 filing and a 19b-4 submission via Cboe BZX on April 8.
Both proposals are now under independent SEC review, each subject to the regulator’s standard approval timelines. If granted, these ETFs would be the first Sui-based investment vehicles available to U.S. investors on public exchanges.
“This development not only validates the growing interest in Sui but could also attract fresh capital into the ecosystem through institutional on-ramps,” said one ETF analyst.
SUI Price Reaction and Technical Outlook
Despite the bullish news, SUI fell nearly 8% on the day of the filing, hitting a local low of $3.40 on May 25. The token has since stabilized, now trading at $3.70, hovering around its 20-day exponential moving average (EMA 20), which is acting as dynamic resistance.
Market analysts suggest that while the ETF filings are promising long-term, traders may remain cautious until regulatory clarity emerges or momentum returns across the altcoin market.
With two heavyweight contenders 21Shares and Canary Capital now in the running, the U.S. may soon see its first spot Sui ETFs if the SEC grants approval. Backed by established custodians and building on international success, 21Shares’ proposal underscores the broader trend of blockchain-native assets entering regulated financial markets. As the SEC begins its review, the battle for Sui ETF dominance is officially underway.
