21Shares, a prominent issuer of crypto exchange-traded products, filed an S-1 registration statement with the U.S. Securities and Exchange Commission (SEC) for a SUI exchange-traded fund (ETF). This filing aims to allow investors to gain exposure to SUI, the native token of the Sui Network, a Layer-1 blockchain developed by Mysten Labs, directly through brokerage accounts.
The ETF’s approval depends on the SEC’s review of the S-1 and 19b-4 forms, marking a significant step toward mainstream institutional adoption of the Sui ecosystem. This follows Canary Capital’s earlier filing for a SUI ETF six weeks prior, reflecting growing institutional interest, with 21Shares also announcing a strategic alliance with Sui to expand global network access.
Additionally, Sui Network is set to integrate sBTC, a one-to-one Bitcoin-backed asset from Stacks, a Bitcoin Layer-2 network, in the coming months. Announced on May 1, 2025, this integration aims to enhance Bitcoin’s role in decentralized finance (DeFi) by enabling BTC holders to earn yield and participate in DeFi protocols on Sui’s scalable, high-performance blockchain while maintaining Bitcoin’s trustless principles. With sBTC’s market cap exceeding $96 million and Sui’s DeFi ecosystem processing billions in transactions, this move positions Sui as a leader in Bitcoin DeFi (BTCfi), potentially attracting more liquidity and developers.

The combination of the ETF filing and sBTC integration has driven bullish momentum for SUI, with its price surging 10.9% to around $3.73 on May 1, 2025, and hovering above $3.40 as of May 2, 2025, despite a minor 1% drop. These developments underscore Sui’s growing prominence in the crypto market, with a market cap of $11.8 billion and over $1.65 billion in total value locked (TVL).
The SUI ETF filing signals growing institutional confidence in Sui as a Layer-1 blockchain. If approved, it would allow traditional investors to gain exposure to SUI through regulated brokerage accounts, bypassing the complexities of crypto wallets or exchanges. This could drive significant capital inflows, mirroring the impact of Bitcoin and Ethereum ETFs, which saw billions in investments.
The ETF aligns with a broader trend of institutional interest in altcoins, as seen with Canary Capital’s earlier SUI ETF filing. This competition among issuers may accelerate regulatory clarity and mainstream adoption of Sui. The ETF news has already contributed to a 10.9% price surge for SUI on May 1, 2025, with the token trading above $3.40 and a market cap of $11.8 billion.
Approval could further elevate SUI’s price by attracting institutional buyers and retail investors, potentially pushing it toward new all-time highs. Increased visibility from the ETF and sBTC integration could enhance Sui’s DeFi ecosystem, which already boasts $1.65 billion in TVL. More liquidity and users may attract developers to build on Sui, reinforcing its position as a scalable, high-performance blockchain.
Integrating sBTC, a Bitcoin-backed asset, positions Sui as a leader in BTCfi, enabling Bitcoin holders to participate in DeFi without selling their BTC. This could unlock billions in dormant Bitcoin capital for yield-generating activities like lending, staking, or liquidity provision on Sui’s DeFi protocols. With sBTC’s market cap at $96 million and growing, its integration could drive significant transaction volume and TVL to Sui, enhancing its network activity and utility.
This aligns with Sui’s high throughput and low-latency design, making it an ideal platform for Bitcoin-based DeFi. The ETF filing and sBTC integration strengthen Sui’s competitive edge against other Layer-1 blockchains like Solana, Aptos, and Sei. By bridging Bitcoin’s massive liquidity with DeFi and gaining institutional backing, Sui could capture market share in both DeFi and traditional finance.
The strategic alliance between 21Shares and Sui for global network access suggests further infrastructure development, potentially including custody solutions or staking services, which could enhance Sui’s appeal to institutions. The ETF’s approval hinges on SEC review, which remains uncertain given the regulator’s cautious stance on crypto ETFs beyond Bitcoin and Ethereum. Delays or rejection could temper short-term bullish sentiment for SUI.
The crypto market’s volatility and regulatory shifts could impact sBTC’s adoption and Sui’s growth. However, Sui’s robust fundamentals (e.g., 25 million daily transactions, $1.65 billion TVL) mitigate some of these risks. A successful SUI ETF could pave the way for other altcoin ETFs, further legitimizing the crypto asset class. It may also pressure regulators to streamline approval processes for crypto investment products.
sBTC’s integration could inspire similar Bitcoin-backed assets on other blockchains, accelerating the growth of BTCfi and cross-chain interoperability. These developments position Sui as a frontrunner in both institutional finance and DeFi, with the potential to drive significant price appreciation, ecosystem growth, and Bitcoin’s utility in decentralized applications. However, regulatory hurdles and market volatility remain key challenges to monitor.
