Canary Grayscale Files for SUI ETF, Highlights U.S. Markets Staking Rewards Potential

Grayscale Investments — known for pioneering regulated crypto investment products — has filed paperwork for a new exchange-traded fund (ETF) tied to SUI, the native token of the Sui blockchain, while emphasizing the potential for U.S. market products to incorporate staking reward structures.

The filing, submitted to the U.S. Securities and Exchange Commission (SEC) through Grayscale’s Canary Grayscale division, signifies a broader push by asset managers to expand regulated investment vehicles beyond Bitcoin and Ethereum into newer Layer-1 ecosystems — while also exploring how staking rewards could be captured within traditional finance products.

SUI ETF Proposal: What’s in the Filing

Details of the proposed SUI ETF indicate:

• The product would hold SUI tokens directly, aiming to track its market performance for U.S. investors without requiring direct custody of the token.

• Grayscale is proposing mechanisms to incorporate staking yields generated by SUI network participation into the ETF’s economics, offering investors exposure to both price appreciation and network income where regulatory frameworks permit.

While spot cryptocy ETFs exist for Bitcoin and Ethereum, regulatory approval for ETFs tied to other Layer-1 networks — especially those involving staking or yield capture — remains more complex. Grayscale’s filing represents an expansion of this strategy as managers look toward diversified crypto product offerings.

Why Staking Rewards Matter to ETF Investors

Staking — where holders lock up tokens to support network security and performance — generates yield over time. Traditionally, investors accumulate these rewards directly through wallets or validator services. Incorporating staking rewards into regulated ETF structures could allow investors to access income-generating crypto strategies without self-custody or direct network participation.

Industry observers say this could bridge DeFi-style yield and traditional financial products, but also note the regulatory hurdles in assigning income streams within a securities product and how rewards are treated under tax rules.

Grayscale’s Strategy: Diversification Beyond BTC and ETH

Grayscale — through both its flagship products and the newly minted Canary division — has been steadily pushing into broader crypto exposure:

• Its Bitcoin Trust and Ethereum ETF have been among the first regulated products to gain wide adoption.

• Other applications and intentions have been reported for ETFs related to Chainlink (LINK), Aave (AAVE) and Dogecoin (DOGE).

Introducing a SUI-linked ETF represents Grayscale’s ongoing ambition to bring regulated crypto exposure to a wider suite of native blockchain assets — especially those with active ecosystems, validator participation, and staking incentives.

Regulatory and Market Considerations

The SEC has historically been cautious about crypto ETFs outside Bitcoin and Ethereum, often focusing on questions of custody, price manipulation, liquidity and investor protection standards. Products that propose to incorporate staking rewards raise additional regulatory questions around yield reporting, valuation timing, and how income accrues to shareholders.

Grayscale’s filing may signal growing confidence that regulators are open — at least in principle — to next-generation ETF structures that capture more than simple price performance. The precise treatment of staking rewards within a regulated fund will likely require further dialogue with regulators.
