21Shares has launched its spot SUI exchange-traded fund (ETF), TSUI, on Nasdaq, providing U.S. investors with regulated access to SUI price exposure through brokerage accounts. The ETF tracks the spot price of the SUI token without granting ownership of the underlying assets and is not registered under the Investment Company Act of 1940. This marks the third spot SUI fund to list within a week, following recent regulatory clearance. The TSUI ETF offers direct price tracking of SUI, allowing investors exposure without holding tokens or managing private keys. However, it carries high volatility and loss risk. This launch follows 21Shares' earlier introduction of a leveraged SUI product in December 2025. The listing is part of a broader trend, with Canary Capital and Grayscale also launching SUI ETFs this week, providing both spot and staking-based exposure options. Despite the new SUI ETF listings, broader market flows show mixed results. SUI's price rose 2.63% in the last 24 hours to $0.8684 but fell 9.55% over the past week. Meanwhile, U.S. spot Bitcoin ETFs saw $204 million in net outflows, and Ethereum spot ETFs recorded $49.48 million in outflows, highlighting ongoing volatility in the crypto ETF market.
