Grayscale has launched the Grayscale Sui Staking ETF (GSUI) on NYSE Arca, providing exposure to SUI and staking rewards. The ETF begins trading after completing regulatory filings with the U.S. Securities and Exchange Commission. GSUI allows market participants to gain access to the Sui network through an exchange-traded product.
The GSUI fund operates as an exchange-traded product, not registered under the Investment Company Act of 1940. As such, it faces higher volatility and risk compared to traditional ETFs and mutual funds. Investors receive exposure to SUI without directly holding the token on personal wallets.
GSUI’s structure includes participation in Sui network staking, enabling rewards to accumulate in the fund’s net asset value. The staking mechanism helps validate transactions and maintain network security. Historical staking yields on the Sui network range between 1.7% and 1.9% annually after fees.
Sui Network Infrastructure and Staking Mechanics
Sui is a blockchain designed for high-speed and low-cost transactions, processing multiple operations in parallel. It offers features like simplified wallet access and offline functionality to support real-world applications. The network is built by the team behind Facebook’s Diem project, giving it an established technology background.
GSUI leverages Sui’s delegated proof-of-stake system, assigning tokens to validators who confirm transactions on the network. Rewards generated through staking are reflected in the fund’s performance. This dual structure combines price appreciation potential with staking income for GSUI holders.
The fund also provides access to Sui’s expanding ecosystem, covering finance, gaming, and consumer applications. Grayscale expects the network to scale further and support complex developer applications. GSUI creates a streamlined channel for exposure to these developments through a regulated product.
Fund Structure and Market Context
GSUI charges a 0.35% annual management fee, currently waived for three months or until reaching $1 billion assets under management. The fund is supported by Bank of New York Mellon for administration and Coinbase as custodian. Market makers like Jane Street and Virtu are expected to provide liquidity and support smooth trading.
The launch of GSUI follows a private placement initiated in August 2024 and a public quotation in November 2025. The fund allows traditional market participants to access the SUI token while earning staking rewards. GSUI marks the first exchange-traded product offering this type of dual exposure to Sui.
A scheduled token unlock in March 2026 will release 43.35 million SUI tokens into circulation. This event could influence supply dynamics, affecting price and market liquidity. Despite SUI’s 69% decline over the past year, GSUI offers a regulated route to participate in staking and token appreciation.
Grayscale manages over 40 products across more than 45 digital assets. GSUI represents its first ETF focused on Sui staking, combining traditional exchange-traded access with blockchain-derived rewards. The fund’s launch strengthens the Sui network’s institutional adoption and market presence.
