Cardano News Today: Institutional Demand Drives Grayscale's Altcoin ETF Expansion Amid Regulatory Review

Grayscale has submitted registration statements to the U.S. Securities and Exchange Commission (SEC) for exchange-traded funds (ETFs) tied to Cardano (ADA), Polkadot (DOT), Avalanche (AVAX), and Dogecoin (DOGE), marking a significant expansion of its crypto product lineup. The filings follow earlier 19b-4 submissions in February 2025, positioning these products for regulatory review. The Cardano ETF, trading under the ticker GADA on NYSE Arca, will track the CoinDesk Cardano Price Index, while the Polkadot ETF, listed as DOT on Nasdaq, will follow the CoinDesk DOT CCIXber Reference Rate.

The filings align with a broader surge in crypto ETF activity, as 92 applications for exchange-traded products are currently pending SEC approval. Most of these are subject to October 2025 deadlines, according to industry analysts.

The regulatory process for these ETFs has been methodical. For instance, Grayscale had already filed 19b-4 submissions with Nasdaq and NYSE Arca in early 2025 to facilitate the listing process. Analysts like James Seyffart of Bloomberg noted that the recent S-1 filings are continuations of prior efforts rather than entirely new initiatives.

Market dynamics further underscore the urgency of these filings. Prediction markets on platforms like Polymarket reflect heightened optimism, with Cardano and Solana showing 87% and 99% approval odds, respectively. This confidence is fueled by the SEC's recent approval of in-kind redemption mechanisms for Bitcoin and Ethereum ETFs, which has set a precedent for broader acceptance.

The technical structures of Grayscale's ETFs emphasize simplicity and security. Both the Cardano and Polkadot ETFs operate through cash-only creation and redemption baskets, processing shares in 10,000-unit increments. Coinbase Custody Trust Company serves as custodian, while the Bank of New York Mellon handles administrative duties. Notably, staking capabilities remain contingent on undefined conditions, with the Polkadot trust anticipating up to 85% of holdings to be staked through provider-facilitated arrangementsGrayscale Submits Polkadot and Cardano ETF …^[5].

Industry experts caution that regulatory risks persist. The Cardano filing explicitly warns that the SEC's prior classification of ADA as a security could trigger adverse impacts, potentially forcing the trust's termination. Despite these uncertainties, the growing pipeline of applications-spanning eight Solana and seven XRP proposals-suggests that market participants are prioritizing speed to capitalize on favorable conditions.

The implications for institutional investing are significant. If approved, Grayscale's ETFs could enable direct exposure to altcoins under clear regulatory oversight, aligning with the SEC's push for standardized compliance pathways. This shift mirrors the broader market's transition from Bitcoin dominance, as evidenced by the Altcoin Season Index stabilizing at 51-a threshold indicating a transition toward diversified crypto investing.
