Grayscale has withdrawn registration statements for three planned U.S. altcoin exchange-traded products on Aug. 7, effectively ending the current registration process for its Cardano, Hedera, and Polkadot funds.

The decision narrows a registration pipeline that Grayscale has built since its 2023 federal court victory over the SEC, a ruling that compelled the agency to allow the conversion of the Grayscale Bitcoin Trust into a spot ETF and helped open the broader U.S. spot crypto ETF market. Grayscale has since positioned itself among the most active issuers pursuing altcoin exchange-traded products, making selective pullbacks from that slate notable for an industry still working to expand beyond Bitcoin and Ethereum ETFs.

SEC records show that the three Form RW submissions were accepted between 4:33:37 p.m. and 4:36:47 p.m. ET — a span of exactly 190 seconds.

These filings represent voluntary withdrawal requests, not SEC rejections. Grayscale stated that it no longer intends to proceed with the planned distribution of shares under those registration statements. The firm also confirmed that none of the registrations had become effective and that no securities had been issued or sold.

Three S-1 Registrations Pulled

The Cardano filing sought withdrawal of registration statement No. 333-289948, originally filed in August 2025. The Hedera request covered No. 333-290129, first filed in September 2025. The Polkadot filing covered No. 333-289949, also originally filed in August 2025.

Each request provides the same core explanation: the sponsor does not intend to proceed with the planned share distribution. The documents offer no separate commercial, demand-related, or regulatory rationale. They also state that no preliminary prospectus had been distributed.

The latest withdrawals follow earlier exits on the exchange listing side. SEC records show NYSE Arca withdrew its proposed rule change for the Grayscale Cardano Trust on Sept. 29, 2025. Nasdaq's proposed rule changes for the Grayscale Polkadot Trust and Grayscale Hedera Trust were both withdrawn on Nov. 3, 2025.

Those exchange proposals were separate from the S-1 registrations withdrawn on Aug. 7. The Hedera review had entered the SEC process in March 2025, as crypto.news reported in its earlier coverage.

New SEC Rules Reshaped the Crypto ETF Approval Route

The regulatory backdrop shifted after the original exchange proposals were filed. In September 2025, the SEC approved generic listing standards allowing qualifying commodity-based trust shares — including digital asset products — to list without a separate Section 19(b) rule change for each fund.

The new standards represented a departure from the SEC's earlier case-by-case review model, under which the agency had for years rejected or delayed spot crypto products before the first Bitcoin and Ethereum ETFs reached the market.

However, the faster exchange route does not replace Securities Act registration. A sponsor still needs an effective registration statement before selling shares. That distinction is significant here because Grayscale withdrew the S-1 layer itself, rather than only the exchange listing proposal.

What Comes Next for Grayscale's Altcoin ETF Slate

Under Rule 477(b), an application to withdraw an entire registration statement before effectiveness is deemed granted upon filing unless the SEC objects within 15 calendar days. The three requests therefore take effect without a separate approval order, unless the Commission intervenes during that window.

The withdrawals do not indicate that the SEC rejected ADA, HBAR, or DOT products, and they do not prevent Grayscale from filing again in the future.

SEC records reviewed Aug. 10 show that preliminary registrations for Bittensor, Aave, BNB, NEAR, and Zcash remain at different stages. The Zcash registration received its third amendment on July 31.

Grayscale also has altcoin products further along in the process. The SEC declared the Grayscale Avalanche Staking ETF registration effective on March 11 and the Grayscale Hyperliquid Staking ETF registration effective on June 2. These differing statuses indicate that the Aug. 7 withdrawals are not evidence of a companywide retreat from altcoin exchange-traded products.

The reason Grayscale ended these three registrations together remains unknown. The filings give no explanation beyond the decision not to proceed, leaving claims about investor demand, economics, or regulatory resistance unconfirmed.
