Cardano ETF Approval Odds Jump to 80% as Grayscale Moves In

Cardano’s ADA token is riding a wave of optimism after traders sharply increased the odds of a spot Cardano ETF getting the green light in 2025.

On decentralized prediction platform Polymarket, the probability of U.S. Securities and Exchange Commission (SEC) approval has surged to 80%. The shift follows a fresh move by Grayscale Investments, which registered the Grayscale Cardano Trust ETF in Delaware, alongside a similar trust for Hedera (HBAR), on August 12, 2025.

While the registrations — handled via CSC Delaware Trust — don’t guarantee approval, they’re a common early step in the ETF process. Typically, they’re followed by S-1 filings with the SEC. “Both networks have growing real-world asset adoption stories, and this step often comes before a spot ETF filing; a green light can bring a wave of institutional capital,” said Web3 researcher Justin Wu.

Why This Matters for Cardano
Grayscale’s expansion beyond Bitcoin and Ethereum into altcoin-focused products reflects a growing institutional appetite for broader crypto exposure. Cardano’s slow-and-steady, peer-reviewed development model and scalable blockchain design have long made it a candidate for regulated investment vehicles.

The SEC has already acknowledged NYSE Arca’s 19b-4 filing for a Cardano ETF earlier this year — a formal step that triggers the review process. While acknowledgement isn’t approval, it’s a sign the proposal is under active consideration.

For many investors, a spot ETF would make owning ADA far simpler by removing the need to manage private keys or digital wallets, potentially opening the door for more mainstream adoption.

Market Impact
ADA responded quickly to the news, jumping nearly 15% in the past 24 hours to $0.88063 at the time of writing. Analysts believe the momentum could continue if a broader, standardized framework for crypto ETFs emerges, potentially allowing multiple spot ETF approvals to be granted at once.
