21Shares has filed a Form 424B3 prospectus supplement with the SEC for TSUI, its spot ETF tracking SUI, the native token of the Sui blockchain. The filing, submitted on or around August 13, 2026, updates investors on the fund’s current state roughly six months after it first began trading.
A 424B3 is a routine but meaningful document. Think of it as the living version of a fund’s original prospectus, updated with fresh financials and any material changes investors need to know about before buying shares.
Where the fund stands
TSUI launched on Nasdaq on February 24, 2026, making it one of the earliest U.S.-listed spot ETFs offering direct exposure to SUI through a standard brokerage account.
As of early August 2026, the fund held approximately $13.3M in assets under management, with a net asset value of around $13.50 per share. Share count grew from roughly 910,000 at the end of June to about 980,000 by August 7, a sign that new capital has been flowing into the product.
