Grayscale Sui Staking ETF Launches on NYSE Arca, Becoming the First Spot SUI Fund on a Major US Exchange

Grayscale Investments is set to launch its Sui Staking ETF (ticker: GSUI) on NYSE Arca on February 19, 2026, according to Cointelegraph. The uplist from the over-the-counter OTCQB market to one of the largest US exchanges marks a watershed moment for the Sui ecosystem: GSUI becomes the first spot SUI fund to trade on a national securities exchange, offering institutional investors direct exposure to both SUI price appreciation and staking rewards.

From OTC Trust to NYSE-Listed Staking ETF

Grayscale originally launched the Grayscale Sui Trust in 2024 as an OTC product trading under the GSUI ticker on OTCQB. The conversion journey began in December 2025 when the asset manager filed its initial S-1 registration statement with the SEC, followed by Amendment No. 1 in January 2026 and a final amendment on February 17.

The restructured product, now officially the Grayscale Sui Staking ETF, represents a meaningful upgrade over the trust format. OTC trust products typically trade at heavy premiums or discounts to their net asset value because they lack the creation and redemption mechanism that keeps ETF prices anchored. With the NYSE Arca listing, authorized participants can create and redeem shares in baskets of 10,000, a mechanism designed to keep the market price tracking the underlying SUI value far more tightly.

The share price is designed to reflect the value of SUI held by the Trust, plus any SUI earned as staking consideration, minus fees and expenses, all benchmarked against the CoinDesk Sui Price Index.

The Service Provider Stack Signals Institutional Seriousness

Grayscale has assembled a lineup of institutional-grade service providers that reads like a blue-chip custody playbook:

Prime Broker and Custodian: Coinbase and Coinbase Custody Trust Company
Transfer Agent and Administrator: The Bank of New York Mellon
Benchmark Index: CoinDesk Sui Price Index

Coinbase's role as custodian stands out. The exchange already serves as custodian for Grayscale's Ethereum (ETHE, ETH) and Solana (GSOL) staking products, which collectively hold over $8.5 billion in assets. BNY Mellon's involvement as administrator adds another layer of traditional finance credibility, given the bank's $46 trillion in assets under custody globally.

The current expense ratio stands at 2.50%, a figure that may draw scrutiny. For comparison, Grayscale's Solana Staking ETF (GSOL) charges just 0.35% and even waived that fee entirely for its first three months or until AUM reached $1 billion. Whether Grayscale offers a similar promotional fee waiver for GSUI at launch could meaningfully influence early adoption.

Five Issuers Are Racing to List SUI Funds

Grayscale is not the only asset manager targeting SUI. At least five issuers have filed for SUI-related ETF products with the SEC:

Grayscale (GSUI): Spot + staking, NYSE Arca
21Shares: Filed for a spot SUI ETF; already launched a 2x leveraged SUI ETF (TXXS) on Nasdaq in December 2025
Canary Capital: Filed an S-1 for a spot SUI ETF in early 2025
Bitwise: Filed in December 2025, becoming the fifth issuer in the race
VanEck: Among the early filers for SUI exposure

The competitive picture mirrors what happened with Bitcoin and Ethereum ETFs, where multiple issuers raced to launch simultaneously. Bitwise has characterized 2026 as an "ETF-palooza" year, projecting more than 100 crypto-linked ETFs could launch in the US during the year. The SEC's publication of generic listing standards for crypto ETPs has removed the case-by-case approval bottleneck, allowing issuers to file under standardized rules covering custody, surveillance sharing, and market structure requirements.

21Shares' leveraged TXXS product, which launched in December 2025, attracted modest initial interest with $1.22 million in AUM and $2.5 million in trading volume within its first two weeks. A spot product like GSUI, with its lower risk profile and staking yield, could attract considerably more capital from institutional allocators who cannot hold leveraged products.

Net yield depends on whether staking beats the 2.50% expense ratio

Grayscale's track record with staking products provides a useful reference point. GSOL, its Solana staking ETF, stakes up to 100% of its SOL holdings at a 7.23% staking reward rate, translating to a net staking reward of approximately 6.60% after the fund's management fee.

The Sui network currently offers staking yields that vary based on validator performance and network conditions. Sui uses a delegated proof-of-stake model where validators stake SUI to participate in consensus, and delegators can earn a share of the rewards. As of late 2025, approximately 3.7 billion SUI tokens out of the initial 10 billion supply were in circulation, with the network's aggregate market capitalization sitting around $5.2 billion.

The staking component is what differentiates GSUI from a simple spot fund. Investors effectively receive SUI price exposure plus staking yield, minus the management fee. Whether the staking yield exceeds the 2.50% expense ratio will be a critical factor for net returns, especially for institutional allocators comparing the product against simply holding SUI in a self-custody wallet.

From ETF Wrapper to Spending Rails

The SUI ETF launch is part of a broader trend of institutional products that are making crypto assets more accessible through traditional financial rails. For everyday crypto users, including those who spend through crypto card products, the implications are indirect but real.

As more institutional capital flows into specific Layer 1 ecosystems via ETFs, it tends to deepen liquidity and stabilize infrastructure around those chains. Sui's growing institutional footprint could accelerate the development of payment and spending applications on the network, similar to how Ethereum's ETF ecosystem has reinforced the chain's position as the primary settlement layer for stablecoin-powered spending cards.

The staking ETF model also highlights a growing theme across the crypto card space: yield-bearing assets that users can hold or spend against. Products from ether.fi already let holders spend against staked Ethereum positions, and Grayscale's push to bring staking yields into regulated ETF wrappers could eventually create new bridges between institutional products and consumer spending tools.

For holders who already own SUI through exchanges like OKX or Gate.io, the ETF launch provides an alternative exposure vehicle within tax-advantaged accounts like IRAs and 401(k)s, something that direct token holdings cannot offer.

Overview

Grayscale's Sui Staking ETF (GSUI) launches on NYSE Arca on February 19, 2026, becoming the first spot SUI fund on a major US exchange. The product bundles SUI price exposure with staking yield, custodied by Coinbase and administered by BNY Mellon. With five issuers now racing to list SUI funds and the SEC's generic listing standards removing regulatory bottlenecks, the altcoin ETF market is expanding rapidly. The key question for investors is whether GSUI's staking yield will be enough to offset its 2.50% expense ratio, and whether Grayscale will follow its Solana playbook with a promotional fee waiver to attract early capital.
