Grayscale withdrew its Cardano Trust ETF registration on Friday, August 7, 2026, filing matching withdrawals for its Hedera and Polkadot trusts roughly ninety seconds apart late that afternoon. A Form RW is a Registration Withdrawal Request, the filing a sponsor submits to pull a registration statement that never went effective, and submitting one is not a rejection from the SEC and not a statement about the underlying asset. The timing is what turns three paperwork withdrawals into a story worth telling. Cardano's six-month CME-futures seasoning period, the clock that had to run before spot ADA ETF filings became eligible for the SEC's generic listing standards, completed two days later on Sunday, August 9. ADA reached that eligibility date with no live Grayscale registration left to activate it.
- Three trusts withdrawn: Grayscale's Cardano, Hedera and Polkadot Trust ETFs, all Form RW filings
- Filing date: Friday, August 7, 2026
- Cardano accession number: 0001193125-26-340377 (CIK 0002083106)
- ADA live price: $0.1973, down 0.50% over 24 hours, per CoinGecko this morning
- Cardano ETF eligibility date: Sunday, August 9, 2026, when the six-month CME futures seasoning clock ran out
That is the news. What follows is harder to write, because our own coverage got this exact story wrong less than 24 hours ago, and the fix starts with saying so before anything else.
What Grayscale Actually Withdrew
Three filings, three trusts, one afternoon. Grayscale's Cardano Trust ETF filed its withdrawal at 4:33:37pm ET, the Hedera Trust ETF followed at 4:34:55pm, and the Polkadot Trust ETF closed the sequence at 4:36:47pm, a span of roughly 190 seconds start to finish, as reported by outlets that reviewed the filings over the weekend.

Each Form RW is reported to carry the same operative language, stating that the Sponsor does not intend to proceed with the planned distribution. None of the three registration statements had been declared effective. No shares were issued or sold under any of them, and no preliminary prospectus went out to investors. A withdrawal at this stage cancels an unused permission slip. It does not undo a product that was live, because none of the three ever went effective, opened for investment or held customer assets.
We Got This Wrong Less Than 24 Hours Ago
Our own article yesterday, Sunday August 9, told you a claim circulating about Grayscale withdrawing its Cardano ETF registration was uncorroborated. We banned the claim from that piece and refuted it twice in the body. The claim was true. We were wrong, and we are saying so directly instead of folding a quiet correction into a later paragraph.
What happened is straightforward. We checked the claim with a web search on a Sunday, looking for coverage of a filing made late Friday afternoon. No outlet had written about it yet, so the search returned nothing useful, and we read an empty result as evidence the claim was unverified rather than what it actually was, a genuine gap in coverage. A search engine can only surface what someone else has already published about a document. It cannot show you a primary filing that nobody has covered yet, and the SEC's own filing history sat there all weekend with the answer already in it.
The fix is not "search harder" next time. It is "check the registry before the coverage" for any claim about a filing, a docket or a registration. That rule applies to us and it applies to you, and it takes under two minutes to do.
How to Check EDGAR Yourself
EDGAR, the SEC's public filing database, lets anyone look up a company's complete filing history for free, and it updates the same day a document is submitted. Search the fund or company name in EDGAR's company search, or if you already have a CIK number, browse straight to that filer's page. Open the filing history and sort by date. The filing at the top of that list is the one that governs, no matter what any headline says a fund is planning.
Grayscale Cardano Trust's EDGAR filing history shows exactly this pattern. An S-1 filed in August 2025, an amended S-1/A in October, and now a Form RW dated August 7, 2026, sitting at the top with nothing filed after it.
A Form RW specifically means a sponsor is asking the SEC to withdraw a registration statement it already submitted. It shows up as the newest filing when a fund abandons a registered offering before that offering ever goes effective. It does not mean the SEC rejected anything, and it does not mean the underlying asset failed some review, because Form RW withdrawals are voluntary and sponsor-initiated. Think of an S-1 as a permit application and a Form RW as the applicant pulling that application before the permit was ever issued. The building lot itself, in this case Cardano's eligibility for a spot ETF, does not change because one applicant walked away from the paperwork.
What This Withdrawal Does Not Mean
Three trusts pulling registrations does not mean the Cardano ETF pipeline is over. Bitwise and Canary are reported to still have their own Cardano ETF filings active, meaning at least two other sponsors have not withdrawn anything, and eligibility under the generic listing standards does not belong to Grayscale alone. Treating one sponsor's exit as the end of the story would repeat the exact kind of unverified leap that produced yesterday's correction in the first place.
There is a second correction bundled into this one. NYSE Arca's Rule 19b-4 exchange filing for a Cardano product, tracked under SR-NYSEArca-2025-12, is reported as withdrawn as of September 29, 2025, months before this weekend's Form RW filings. Our earlier coverage described that 19b-4 as still pending. It was not, and the generic listing standards process that took effect this year changed the mechanics enough that a standalone 19b-4 approval is no longer the gating step it used to be for an asset with a seasoned futures market behind it.
The Six-Month Clock That Made the Timing an Irony
CME's Cardano futures went live on February 9, 2026, starting a six-month clock the SEC's generic listing standards require before a spot ETF tied to Cardano's underlying network can qualify for the streamlined approval track. That clock ran out on Sunday, August 9, the same weekend Grayscale's withdrawal became public knowledge. Two days earlier, on Friday afternoon, Grayscale had already pulled the one registration built to activate the moment eligibility arrived.
That sequencing is the actual story here, not a signal about ADA's prospects and not evidence of coordination. A sponsor can decide a filing no longer fits its product roadmap for reasons that have nothing to do with a token's fundamentals, and the six-month clock keeps running regardless of who is or is not still holding a ticket when it hits zero. We covered Grayscale's own October 2026 target date for a Cardano launch back when that trust was still an active filing. That target is now moot for Grayscale specifically, though it says nothing about Bitwise's or Canary's timelines.
The Tape Right Now and What Would Change It
ADA trades at $0.1973, down 0.50% over the past 24 hours, per CoinGecko at the time of writing this morning. That is a step back below the $0.20 level ADA had been pressing toward heading into the eligibility date, and it puts real distance between the price action and the regulatory story. Markets did not treat Sunday's eligibility date as a catalyst, and Friday's withdrawals barely registered before this weekend's coverage caught up with them.
XRP's spot ETF products sit on the other side of this same week, still taking in new money in thin amounts, a split we're covering separately today. Wednesday's CPI print and the Fed's still-36% hike odds are a different thread entirely, tracked in today's macro piece.
What would actually change this picture is a new S-1 filing, either a fresh one from Grayscale or an amendment signaling intent to reactivate, or a move from Bitwise or Canary that pushes one of their existing filings toward an effective date. Until one of those things happens, Cardano's ETF eligibility is real and unclaimed at the same time, a stranger outcome than a clean yes or no and closer to what actually happened this weekend.
Frequently Asked Questions
Did Grayscale cancel its Cardano ETF?
Grayscale withdrew the registration statement for its Cardano Trust ETF on August 7, 2026, along with matching withdrawals for its Hedera and Polkadot trusts. The registration had never gone effective and no shares had been issued, so this ended a filing rather than a live product.
What is a Form RW filing with the SEC?
A Form RW is a Registration Withdrawal Request, the document a sponsor files to pull a registration statement before it takes effect. It is a voluntary, sponsor-initiated filing, not an SEC rejection, and it carries no judgment about the asset the registration covered.
Is Cardano still getting a spot ETF?
Cardano cleared the SEC's eligibility threshold for streamlined spot ETF review on August 9, 2026, when its six-month CME futures seasoning period finished. Bitwise and Canary are reported to still have active Cardano ETF filings, so eligibility has not disappeared even though Grayscale's registration has.
Why did Grayscale withdraw its Hedera and Polkadot ETFs at the same time?
All three withdrawals were filed within about 190 seconds of each other on August 7, 2026, and the filings use matching language stating the sponsor does not intend to proceed with the planned distribution. Grayscale has not published a separate commercial explanation for any of the three beyond that shared statement.
Bottom Line
Three Form RW filings ended three unused Grayscale registrations, not the Cardano ETF story, and Bitwise and Canary reportedly still have live filings sitting on the same eligibility date Grayscale missed by two days. If either of those sponsors moves toward an effective date in the coming weeks, that is the signal worth watching, not another rumor about who withdrew what. If Grayscale instead files something new against the same eligibility window, treat it as a second attempt rather than a reversal. Check EDGAR directly before trusting any headline about a filing status, ours included, because that single habit is the difference between yesterday's mistake and today's correction.
