Grayscale has withdrawn SEC registration statements for its planned Cardano, Hedera, and Polkadot exchange-traded funds, removing three proposed altcoin offerings from the asset manager's current pipeline.

SEC filings accepted on August 7 within a span of approximately 190 seconds should not be interpreted as regulatory rejection orders. The Grayscale Cardano Trust ETF registration was removed first at 4:33:37 p.m. Eastern Time, followed by the Grayscale Hedera Trust ETF at 4:34:55 p.m. and the Grayscale Polkadot Trust ETF at 4:36:47 p.m.

The Form RW filings cited Rule 477 and confirmed that no shares would be distributed under the registrations, which had remained ineffective. The filings further stated that no securities had been issued or sold and that no preliminary prospectuses had been distributed under any of the three registrations. Rule 477 withdrawals are a standard SEC mechanism that issuers use to pull registration statements; they are commonly employed for administrative reasons and do not preclude a subsequent refiling.

Grayscale did not provide a public explanation for removing the proposed products from its ETF pipeline. The withdrawal filings themselves offer no indication of the underlying rationale.

Prior Exchange-Level Withdrawals

The registration withdrawals follow earlier changes at the exchange level. According to SEC records, NYSE Arca withdrew its listing proposal for the Cardano product on September 29, 2025. Nasdaq records show that listing proposals for the Polkadot and Hedera products were withdrawn on November 3, 2025.

These exchange proposals and ETF registration statements served distinct regulatory functions. The exchange proposals governed the listing and trading of the products on national securities exchanges, while the registration statements related to the offering of shares to investors. The August 7 withdrawals represent an independent regulatory step that removes the current registration statements from SEC consideration.

The broader regulatory landscape has shifted since Grayscale initially pursued these altcoin products. In September 2025, the SEC approved generic listing standards for qualifying commodity-based trust shares. Under those standards, eligible spot digital-asset products may list without separate product-specific Section 19(b) proposals, though issuers must still satisfy Securities Act registration requirements before launch. That framework change altered the path to market for crypto ETFs, potentially making exchange-level proposals unnecessary for qualifying products while keeping the Securities Act registration step intact.

Remaining Grayscale Altcoin Filings

As of August 8, other Grayscale altcoin registrations remained at various stages in the approval process. Proposed products tied to Bittensor, Aave, BNB, NEAR, and Zcash were still in preliminary stages. Meanwhile, the Grayscale Avalanche Staking ETF and the Hyperliquid Staking ETF had already reached effectiveness milestones. Grayscale is one of several asset managers pursuing altcoin ETF products, and its registration pipeline sits alongside filings from competitors seeking similar offerings in a still-developing market segment.

The withdrawals narrow one segment of Grayscale's altcoin ETF pipeline but do not signal an end to the company's broader strategy. The filings remove specific registration statements without establishing that Grayscale has abandoned ADA, HBAR, or DOT products entirely. The submissions contain no evidence attributing the decision to demand factors, regulatory concerns, or any other specific cause.

Potential next steps to monitor include replacement registrations, revised product structures, or additional exchange filings for these assets.
