Grayscale Crypto ETFs Filing News: Polkadot & Cardano ETF Coming Soon?

Grayscale Investments has made a major move towards expanding its cryptocurrency exchange-traded funds (ETFs) portfolio. Recently, the company has submitted an S-1 registration with the U.S. Securities and Exchange Commission (SEC) to introduce ETFs of Polkadot (DOT) and Cardano (ADA). This filing builds on its prior 19b-4 filings and highlights the continued effort by Grayscale to deliver diversified crypto investment products to retail and institutional investors.

The announcement shows that the company remains committed to altcoins other than Bitcoin and Ethereum, as the market is becoming more interested in multi-chain solutions and new blockchain networks.

Routine Filing, Not a New Application

Grayscale explained that the S-1 registration is a standard procedural process in its product listing procedure and not a new application. This will guarantee that the SEC regulations are followed, and the introduction of cryptocurrency ETFs into the public market will have an easy way to go.

Such filings are typical, according to financial analysts, of asset managers who want to broaden investment offerings without prompting a completely new regulatory examination. The S-1 registration is an indication that it is ready to launch its ETFs, without compromising the investor protection and disclosure rules of the SEC.

Including DOT and ADA in its ETF offerings, Grayscale will target investors seeking to diversify their portfolios beyond the conventional crypto heavyweights, but also invest in potentially high-potential blockchain networks.

Market Implications

The news is announced as institutional interest in cryptocurrency exchange-traded funds grows. Although Bitcoin and Ethereum have traditionally been the most popular digital assets, other types of cryptocurrencies like DOT and ADA are becoming increasingly popular as potential investments.

According to market observers, the filings by Grayscale might open the door to a wider aspect, which would broaden market liquidity and attract more investors to the sector. Authorization would give regulated and transparent access to these cryptocurrencies, which could increase retail and institutional investment.

Grayscale's Files Registration for Other ETFs

Grayscale is not restricted to Polkadot and Cardano. The company has also registered several S-1s of altcoins such as Solana (SOL), Hedera (HBAR), Dogecoin (DOGE), Avalanche (AVAX), and SuSui-basedokens. Others are organized in the form of Delaware statutory trusts, the arrangement of current altcoin trusts such as Dogecoin and Avalanche.

These reports reflect the approach of Grayscale to controlled exposure to altcoins, where fund fees, staking arrangements, and trading structures vary. Dogecoin and Avalanche ETFs , for example, have generated notable market interest, signaling rising institutional attention toward memecoins and high-potential altcoins. The SEC oversight provides investor security and custody safety, and approvals may lead to liquidity, adoption, and price action in these cryptocurrencies.

Broader ETF Market Trends

The surge in Grayscale’s filings coincides with a historic growth in U.S. ETFs. As of August 2025, the number of ETFs exceeded individual stocks for the first time, surpassing 4,300 funds compared to approximately 4,200 stocks. The growth is an indication of increased investor interest in diversified, accessible, and thematic investment products.

Other recent proposals include 21Shares’ SEI token ETF with Coinbase custody, Bitwise’s Chainlink (LINK) ETF, Canary Capital’s TRUMP memecoin ETF, and XRP ETFs approval timeframe revealed as asset managers update filings . The filings boom highlights the popularity and the innovation that have been highly competitive in the fast-growing market.

Conclusion

The S-1 registration is filed, and the SEC will analyze the submissions of Grayscale for Polkadot and Cardano. However, around 92 Exchange Traded Products (ETPs) are pending for approval , including XRP and Solana, leading the pathways. Investors and market watchers are awaiting for SEC’s next move to get the approval.
