Grayscale and Canary Capital announced the launch of two spot SUI ETFs on February 18, GSUI on NYSE Arca and SUIS on Nasdaq. Both funds provide exposure to SUI's spot price and incorporate staking rewards, with historical annual yields of 1.7%–3.3%, according to Grayscale. GSUI evolved from the conversion of Grayscale’s SUI Trust, combining spot holdings with active on-chain staking. SUIS mirrors this model on Nasdaq. The products aim to expand regulated access to blockchain-based yield opportunities.
