Grayscale has resubmitted filings for both Cardano and Polkadot exchange-traded funds (ETFs), aiming to secure regulatory approval from the U.S. Securities and Exchange Commission (SEC). The latest updates, filed under updated S-1 registration statements, detail plans for direct cryptocurrency holdings within these ETFs, without leveraging derivatives or complex strategies. 87% of analysts now expect the Cardano ETF to be approved as SEC review timelines remain extended. While Grayscale’s earlier filings were initially rejected, recent developments suggest a renewed focus on regulatory approval with Cardano’s ETF gaining traction. The SEC has extended its review period for the Cardano ETF, pushing it from August to late October, 2025. This follows an increase in investor confidence following Grayscale’s latest updates and Grayscale’s existing Bitcoin and Ethereum ETFs. Analysts anticipate a surge in the Cardano ETF approval rate as the SEC reviews 96 crypto ETF applications including Solana, XRP, Ethereum, Bitcoin, and Litecoin. Polkadot ETF filings have also been updated for listing on Nasdaq.
