21Shares SUI and Polkadot ETFs Gain DTCC Listing, Fueling SEC Approval Buzz

The crypto ETF race in the United States just got hotter. In a move that has sent ripples across the digital asset industry, 21Shares’ SUI and Polkadot ETFs have been officially listed on the Depository Trust & Clearing Corporation (DTCC) website. While this does not mean an automatic green light from the U.S. Securities and Exchange Commission (SEC), analysts believe it signals significant progress toward formal approval. With deadlines for both ETFs approaching in November and December, many experts argue that the long-awaited era of diverse crypto ETFs may finally be here.

DTCC Listing surge Optimism

The DTCC plays a key role in the U.S. financial system by handling clearing and settlement for securities. When an ETF is listed on its website, it indicates preparations for market entry, even though SEC approval is still required.

This week, two new listings appeared on DTCC’s platform:

• 21Shares SUI ETF (TSUI)

• 21Shares Polkadot ETF (TDOT)

The news quickly made waves in the crypto community. Bloomberg’s senior ETF analyst Eric Balchunas even described it as confirmation that the “crypto ETF approval season has officially arrived.”

SEC Deadlines Approaching

According to Bloomberg ETF analysts, the 21Shares Polkadot ETF has a 90% chance of approval, while the 21Shares SUI ETF sits at 60% odds. The final SEC deadlines are:

• November 2025 → Polkadot ETF decision

• December 2025 → SUI ETF decision

These deadlines are critical because the SEC has the power to either approve or deny the ETFs, regardless of DTCC listing status. However, the fact that DTCC has included them in its system suggests issuers are preparing for launch.

Why It Matters for Crypto Investors

ETFs (Exchange-Traded Funds) allow investors to gain exposure to crypto assets without directly buying or managing tokens themselves. This is particularly important for institutional investors who need regulated, secure, and liquid vehicles for investment.

Bitcoin and Ethereum ETFs have already proven their success, attracting billions in inflows within months of approval. The addition of SUI and Polkadot ETFs could further diversify the market and encourage capital inflows into smaller but high-potential blockchain ecosystems.

• SUI (Sui Network) → A layer-1 blockchain built for scalability and speed.

• Polkadot (DOT) → A multi-chain platform designed to connect multiple blockchains seamlessly.

Both projects represent the “next generation” of blockchain infrastructure. If their ETFs get approved, it could put them on the map for mainstream investors in the same way that Bitcoin and Ethereum already have.

Market Reactions to the News

The listing had an immediate impact on price action:

• SUI jumped nearly 4%, rebounding from a 24-hour low of $3.16 to $3.31, before stabilizing around $3.23.

• Polkadot (DOT) rose 2% in the same period, climbing from $3.81 to $3.94, before settling at $3.90.

While the gains were modest, they reflected growing optimism. However, trading volumes for both tokens dipped—SUI saw a 12% decline, while DOT recorded a 24% drop—indicating that many traders remain cautious until SEC approval is confirmed.

Comparing to Other ETF Developments

This is not the first time crypto ETFs have appeared on DTCC’s radar. Recently, Fidelity’s Solana ETF (FSOL), Canary’s XRP ETF (XRPC), and Canary’s Hedera ETF (HBR) also surfaced on the listing platform.

Together, these developments suggest that multiple crypto projects could soon join Bitcoin and Ethereum in the regulated ETF space. If approved, these ETFs would not only boost investor access but also strengthen the legitimacy of altcoins in traditional finance.

Analyst Views: Cautious Optimism

While excitement is building, experts caution against assuming DTCC listing guarantees approval. As Bloomberg analysts point out, the SEC remains the final authority.

Historically, the SEC has delayed, rejected, or requested amendments to ETF applications, especially when it comes to altcoins. Recently, the regulator even asked ETF issuers to withdraw 19b-4 forms in order to comply with General Listing Standards. This demonstrates that hurdles remain.

Still, analysts believe that the political and economic climate is shifting toward greater acceptance of crypto ETFs. The U.S. market is seeing increased demand for diversified exposure, and regulatory bodies may face pressure to expand beyond Bitcoin and Ethereum.

Potential Impact if Approved

If the SEC grants approval in the coming months, SUI and Polkadot ETFs could trigger several key outcomes:

1. Institutional Capital Inflows – Hedge funds, pension funds, and asset managers could allocate to DOT and SUI.

2. Price Stability and Growth – Broader adoption via ETFs could reduce volatility while boosting long-term valuations.

3. Legitimacy for Altcoins – DOT and SUI would gain recognition as serious contenders in the blockchain sector.

4. Market Expansion – Approval could pave the way for more niche ETFs, including DeFi, gaming, and Web3-focused funds.

Conclusion

The DTCC listing of 21Shares SUI and Polkadot ETFs marks a major milestone in the ongoing evolution of crypto investment products. While it does not guarantee SEC approval, it shows clear progress and signals confidence among issuers.

With final decisions due in November (Polkadot) and December (SUI), the next few months could be pivotal for the crypto ETF landscape. If approved, these ETFs would not only provide new investment avenues but also reinforce the growing narrative that crypto is maturing into a legitimate asset class for global markets.

For now, investors are watching closely as the U.S. inches closer to what some analysts are calling the “crypto ETF approval season.”
