Grayscale expands crypto lineup with Sui Staking ETF — Grayscale lists GSUI on NYSE Arca

Grayscale Investments launched its Sui Staking ETF, marking one of the first U.S.-listed exchange-traded funds to combine direct crypto exposure with on-chain yield generation.

The fund began trading on NYSE Arca under the ticker GSUI after the company filed a Form 8-A with the Securities and Exchange Commission and secured exchange approval, expanding the asset manager’s growing suite of digital-asset investment products., CoinPedia reports.

A hybrid of ETF access and staking yield

Unlike traditional spot crypto ETFs that simply hold tokens, GSUI is structured to generate additional income by staking SUI, the native token of the Sui blockchain. Staking allows token holders to help validate network transactions and secure the protocol in exchange for rewards.

The ETF carries a 0.35% management fee, though Grayscale said the fee will be waived for the first three months or until assets reach $1 billion, whichever comes first—a strategy aimed at attracting early institutional and retail participation.

The fund’s operational backbone reflects institutional-grade infrastructure. Bank of New York Mellon will provide administration and transfer agency services, while Coinbase will act as custodian and prime broker. Liquidity support is expected from major market makers including Jane Street and Virtu, which typically facilitate tighter spreads and smoother trading in ETF markets.

Institutional framework meets crypto innovation

The product builds on Grayscale’s earlier staking-enabled vehicles and comes as asset managers race to introduce differentiated crypto ETFs beyond passive price tracking. By incorporating staking rewards, GSUI offers what could be described as a dual-return structure: potential capital appreciation of SUI alongside blockchain-based yield.

Sui’s market capitalization stands near $4 billion, though the token has fallen roughly 69% over the past year, reflecting broader volatility across altcoins. On March 1, approximately 43.35 million SUI tokens are scheduled to unlock, increasing circulating supply and potentially adding short-term price pressure. Across the broader market, nearly $911 million worth of tokens are expected to unlock over the next 30 days.

Bitcoin dominance remains around 58%, suggesting capital continues to favor larger digital assets even as new ETF products enter the market.

A test for altcoin ETFs

The launch of GSUI signals growing regulatory comfort with more complex crypto structures, but its performance may hinge on market conditions. If SUI stabilizes amid upcoming token unlocks, the ETF’s yield component could prove attractive. Conversely, sustained selling pressure could test investor appetite for altcoin-focused funds.

Grayscale’s move underscores a broader shift toward blending traditional financial wrappers with blockchain-native income mechanisms.
