S-1/A: Grayscale Cardano Trust ETF Files S-1/A for ADA Spot ETF

Grayscale Cardano Trust ETF files an amended registration statement for a spot Cardano (ADA) ETF, aiming to provide investors with exposure to ADA, including potential staking rewards, while highlighting significant digital asset market risks and regulatory uncertainties.

Summary

• The Grayscale Cardano Trust ETF is a Delaware statutory trust designed to hold ADA, a digital asset on the Cardano Network, and aims for its Shares to reflect the value of ADA held, including any ADA earned from staking, less expenses.
• The Trust intends to list its Shares on NYSE Arca under the symbol GADA, offering investors a cost-effective and convenient way to gain investment exposure to ADA.
• Currently, the Trust only supports 'Cash Orders' for creation and redemption of Shares, where Authorized Participants deposit or receive cash, and a Liquidity Provider handles the ADA exchange; 'In-Kind Orders' (direct ADA exchange) require further regulatory approval.
• The Trust is currently prohibited from engaging in staking activities because the 'Staking Condition' (tax guidance ensuring grantor trust status) has not yet been met, with no assurance as to when it will be satisfied.
• As of September 30, 2025, approximately 35.4 billion ADA were in circulation, with a 24-hour trading volume of approximately $337.5 million and an aggregate market value of $28.9 billion, making ADA the tenth largest digital asset by market capitalization as of October 16, 2025.
• The Index Price, used to calculate the Trust's NAV, is derived from the CoinDesk ADA CCIXber Reference Rate, which aggregates data from multiple Digital Asset Trading Platforms (Bitfinex, Bitstamp by Robinhood, Bybit, Crypto.com, Kraken, OKX) to mitigate manipulation.
• The Sponsor purchased 10 Seed Shares for $100 ($10.00 per share) on October 15, 2025, which are expected to be redeemed for cash prior to the NYSE Arca listing.

Sentiment

Score: 5

Explanation: The filing is a registration statement for a new ETF, presenting both opportunities for investors to gain exposure to ADA and extensive disclosures of significant risks and regulatory uncertainties. The cautious and legally defensive tone, particularly regarding the SEC's past stance on ADA as a security and the unresolved status of in-kind creations/redemptions and staking, balances any positive sentiment from the intent to list.

Positives

• The Trust is designed to provide investors with a cost-effective and convenient way to gain investment exposure to ADA without directly managing digital assets.
• An arbitrage mechanism is expected to keep the value of the Shares closely linked to the Index Price, promoting efficient market pricing.
• The Trust employs robust security protocols for ADA custody, including offline storage (cold storage) for a substantial portion of assets, multiple encrypted private key shards, and geographic distribution of secure vaults.
• The Sponsor is obligated to assume and pay most ordinary course operational and periodic expenses of the Trust, excluding taxes, in exchange for the Sponsor's Fee.
• The Trust's NAV and NAV per Share will be published daily on its website, providing transparency to investors.
• The Trust will not utilize leverage, derivatives, or similar arrangements, offering a straightforward investment vehicle.
• Potential for additional ADA to be earned as 'Staking Consideration' if the 'Staking Condition' is satisfied, enhancing potential returns.

Negatives

• ADA trading prices have experienced and may continue to experience extreme volatility, which could materially adversely affect the value of the Shares.
• The Shares may trade at a price that is at, above, or below the Trust's NAV per Share, potentially leading to losses for investors.
• The Trust is currently unable to facilitate in-kind creations and redemptions of Shares, which could impair the arbitrage mechanism and result in wider bid/ask spreads and reduced liquidity.
• Staking is currently prohibited due to the 'Staking Condition' not being met, potentially placing the Shares at a comparative disadvantage to direct ADA investments or other vehicles that can stake.
• Shareholders could incur tax liabilities from staking rewards without receiving corresponding distributions from the Trust, requiring other sources of funds to satisfy tax obligations.
• The digital asset market is largely unregulated and lacks transparency, increasing risks of fraud, market manipulation, business failures, and security breaches.
• There is concentrated ownership of ADA, with the largest 100 wallets holding approximately 29% of ADA in circulation, which could lead to adverse price effects from large sales.
• The SEC has previously taken the view that ADA is a security, and a final determination to that effect could significantly impact ADA's value and potentially lead to the Trust's termination.
• The Trust relies on third-party service providers, and disruptions to their operations, business failures, or security breaches could adversely impact the Trust's ability to access critical services or lead to asset loss.
• The Custodian's liability for losses is capped, and the Trust's ADA holdings are not fully insured, exposing shareholders to potential unrecoverable losses.
• Shareholders have limited voting rights and restricted rights to bring derivative actions, giving almost all control to the Sponsor and Trustee.
• The Sponsor and its affiliates have potential conflicts of interest, including managing other investment vehicles and proprietary trading, which may not always align with the Trust's or shareholders' best interests.
• The Trust may be required to terminate and liquidate at a time disadvantageous to shareholders, such as when ADA prices are depressed.
• The Trust's status as an 'emerging growth company' means reduced disclosure requirements, which some investors may find less attractive.

Risks

• Extreme volatility of ADA trading prices, potentially leading to substantial loss of value.
• Uncertain medium-to-long term value of Shares due to evolving blockchain technologies and digital asset characteristics.
• Dependence on the acceptance and growth of digital assets like ADA.
• Concentrated ADA ownership could lead to adverse price effects from large sales.
• Recent digital asset market disruptions (e.g., FTX, Celsius, Voyager, Three Arrows Capital failures) caused extreme volatility, loss of confidence, and liquidity declines.
• Largely unregulated nature and lack of transparency of Digital Asset Trading Platforms, leading to fraud, manipulation, business failures, and security issues (e.g., wash-trading, front-running).
• Risk of validators suffering losses or staking becoming unattractive, affecting the Cardano Network.
• Temporary or permanent forks or clones of the Cardano Network could adversely affect ADA value.
• Lack of active trading markets for Shares may result in losses upon disposition.
• Illiquid markets may exacerbate losses or increase NAV/market price variability.
• Less liquidity or wider spreads for Shares compared to other spot ADA ETPs if approved.
• Limited history of the CoinDesk ADA CCIXber Reference Rate (Index).
• Competition from other digital assets (Bitcoin, Ether, Polkadot, Avalanche, Solana) and private blockchain platforms (J.P. Morgan's Kinexys).
• Liquidity of Shares affected if Authorized Participants cease obligations or Liquidity Engager fails to engage providers.
• Suspension of redemption program may cause Shares to trade at a discount.
• SEC's previous view that ADA is a security; a final determination could adversely affect ADA value and lead to extraordinary expenses or Trust termination.
• Regulatory changes or actions by U.S. Congress or agencies (FinCEN, OFAC, SEC, CFTC, IRS) may restrict ADA use or network operations.
• Changes in SEC policy could adversely impact Shares (e.g., approval of competing ETFs).
• Foreign regulatory changes (China, South Korea, UK, EU MiCA) could affect ADA value globally.
• Risk of Authorized Participant, Trust, or Sponsor being regulated as a money service business/transmitter, leading to expenses and decreased liquidity.
• Regulatory changes could obligate Trust/Sponsor to register, incurring extraordinary expenses.
• Potential conflicts of interest among Sponsor, affiliates, and Trust.
• Discontinuance of Sponsor's services could be detrimental.
• Lack of ability to facilitate in-kind creations/redemptions could have adverse consequences.
• Custodian resignation/removal without replacement could trigger early Trust termination.
• Inability to participate in Staking (if Staking Condition not satisfied) could have adverse consequences.
• Staking introduces risk of ADA loss.
• Dependence on third parties for Staking Arrangements.
• Uncertain regulatory landscape surrounding Staking (e.g., deemed a security).
• Potential tax liabilities for beneficial owners from staking without distributions.
• Reliance on third-party service providers (Custodian, Prime Broker, Transfer Agent, Administrator, Marketing Agent).
• No guarantee of an active trading market for Shares.
• Reduced disclosure requirements as an 'emerging growth company' may make Shares less attractive.
• Inability of Authorized Participants/market makers to hedge ADA exposure may affect liquidity.
• Arbitrage mechanism may be problematic if creation/redemption process encounters difficulties.
• Congestion or delay in the Cardano Network may delay ADA purchases/sales.
• Competition from central bank digital currencies (CBDCs) and emerging payments initiatives.
• Stablecoin volatility or operational issues could impact ADA prices.
• Cardano protocol components (Ouroboros proof-of-stake) are new and may not function as intended.
• Security threats to Trust's Vault Balance or Settlement Balance could result in loss of assets.
• ADA transactions are irrevocable; incorrectly transferred ADA may be irretrievable.
• Lack of full insurance and limited legal recourse against service providers.
• Trust may be required to terminate and liquidate at a disadvantageous time.
• Shareholders have limited voting rights and restricted derivative action rights.
• Sponsor's sole responsibility for NAV calculation; errors could adversely affect value.
• Extraordinary expenses (e.g., taxes, litigation) borne by the Trust, requiring ADA sales.
• Taxable events for shareholders from ADA transfers/sales for expenses without distributions.
• Intellectual property rights claims may affect Trust.
• Pandemics, epidemics, disasters could negatively impact holdings/operations.
• Shareholders may not receive benefits of forks or airdrops (Trust irrevocably abandons them).
• Coinbase Global (Custodian/Prime Broker parent) serves competing products, creating potential resource allocation issues.
• Authorized Participants may serve competing products, affecting arbitrage.
• Shareholders not Authorized Participants can only trade in secondary markets, subject to premiums/discounts.
• Sponsor may amend Trust Agreement in ways not aligned with shareholder interests or increasing tax risk.
• Uncertain U.S. federal income tax treatment of digital assets and staking.
• U.S. tax-exempt shareholders may recognize UBTI from staking.
• Non-U.S. Holders may be subject to U.S. federal withholding tax on staking rewards/forks/airdrops.

Future Outlook

The Trust intends to list its Shares on NYSE Arca under the symbol GADA, with the Sponsor expecting an effective arbitrage mechanism to keep share value linked to the Index Price. The future availability of in-kind creations and redemptions is contingent on obtaining 'In-Kind Regulatory Approval.' The Trust may engage in staking to earn ADA rewards if the 'Staking Condition' (favorable tax guidance for grantor trust status) is satisfied, with the Sponsor planning to stake most ADA holdings and implement a staking policy prior to listing. The Cardano Network is progressing towards its Voltaire phase, which will transfer governance to ADA holders. Regulatory bodies like the SEC and CFTC are actively working on comprehensive frameworks for digital assets, which could impact the Trust and the broader industry.

Management Comments

• The Sponsor believes that the security procedures in place for the Trust, including, but not limited to, offline storage, or cold storage, for a substantial portion of the Trusts ADA, multiple encrypted private key shards, usernames, passwords and 2-step verification, are reasonably designed to safeguard the Trusts ADA.
• The Sponsor believes that momentum pricing of ADA has resulted, and may continue to result, in speculation regarding future appreciation in the value of ADA, inflating and making the Index Price more volatile.
• The Sponsor believes that it is generally more efficient, and therefore less costly, for spot commodity exchange-traded products to utilize in-kind orders rather than cash orders, because there are fewer steps in the process and therefore there is less operational risk involved when an Authorized Participant can manage the buying and selling of the underlying asset itself, rather than depend on an unaffiliated party such as the issuer or sponsor of the exchange-traded product.
• The Sponsor believes the Index Providers selection process for Constituent Trading Platforms as well as the methodology of the Index Prices algorithm provides a more accurate picture of ADA price movements than a simple average of Digital Asset Trading Platform spot prices, and that the weighting of ADA prices on the Constituent Trading Platforms limits the inclusion of data that is influenced by temporary price dislocations that may result from technical problems, limited liquidity or fraudulent activity elsewhere in the ADA spot market.
• By referencing multiple trading venues and weighting them based on trade activity, the Sponsor believes that the impact of any potential fraud, manipulation or anomalous trading activity occurring on any single venue is reduced.
• The Sponsor has not observed a material difference between the Index Price and average prices from the constituent Digital Asset Trading Platforms individually or as a group.

Industry Context

The Grayscale Cardano Trust ETF operates within a rapidly evolving and highly competitive digital asset industry. The Cardano Network, utilizing a proof-of-stake consensus mechanism (Ouroboros), is a prominent smart contract platform competing with established networks like Ethereum, Bitcoin, Polkadot, Avalanche, and Solana, as well as private blockchain initiatives from financial institutions like J.P. Morgan's Kinexys. The broader digital asset market is characterized by extreme volatility, concentrated ownership, and significant regulatory uncertainty, with U.S. and foreign governments actively developing and enforcing regulations. Recent market disruptions, such as the FTX collapse, have intensified scrutiny and highlighted the need for robust regulatory frameworks. The emergence of central bank digital currencies (CBDCs) and financial institution-led payment initiatives also poses competitive challenges to ADA and other cryptocurrencies.

Comparison to Industry Standards

• The Trust's current reliance on 'Cash Orders' for creations and redemptions is a novel approach for a spot commodity exchange-traded product, differing from traditional commodities like gold and silver ETFs that typically employ more efficient in-kind mechanisms.
• The Trust's security measures, including cold storage, multiple encrypted private key shards, and geographically distributed secure vaults, are presented as enhanced compared to some other digital asset financial vehicles.
• The Trust directly owns actual ADA, distinguishing it from other digital asset financial vehicles that may provide exposure through derivatives or other financial instruments.
• ADA is supported by fewer trading platforms compared to more established digital assets like Bitcoin and Ether, which could potentially impact its liquidity.
• The Cardano Network's Ouroboros proof-of-stake consensus mechanism is a relatively recent innovation and has not been tested at scale over as long a period as traditional proof-of-work blockchains (e.g., Bitcoin).
• Coinbase Global, the parent company of the Trust's Custodian and Prime Broker, is a leading digital asset custodian and prime execution agent, also serving several competing exchange-traded ADA products, which could lead to resource allocation challenges or perceived favoritism.
• The Trust faces competition from other spot ADA exchange-traded products, some of which have already received SEC approval, potentially impacting its market share and liquidity.

Management Changes

Corporate Governance

Legal Proceedings

• Neither the Sponsor nor the Trust were party to legal proceedings required to be disclosed during the periods covered by the financial statements.
• The filing references past SEC enforcement actions against Binance, Coinbase, and Kraken, which were dismissed between February 2025 and May 2025.
• It also mentions the SEC's 2020 complaint against Ripple Labs (XRP), with a District Court ruling in July 2023 and appeals dismissed in August 2025.
• Further SEC enforcement actions against Mango Labs, LLC (September 2024) and Cumberland DRW, LLC (October 2024, dismissed March 2025) are noted.
• DOJ arrests and charges against developers of Samourai Wallet (April 2024) and a co-founder of Tornado Cash (May 2024 sentencing, August 2025 conviction/mistrial) are cited in the context of illicit activities and privacy-enhancing digital assets.

Related Party Transactions

• Digital Currency Group, Inc. (DCG), the indirect parent company of the Sponsor, holds a minority interest of less than 1.0% in Kraken, one of the Digital Asset Trading Platforms included in the Index.
• DCG has investments in a large number of digital assets and companies within the digital asset ecosystem, including trading platforms and custodians, which could create conflicts of interest regarding the Cardano Network's development or specific digital assets.
• The Sponsor and Grayscale Securities are affiliates, and the Sponsor may engage other affiliated service providers in the future, potentially leading to disincentives to replace them.
• Officers of the Sponsor may trade ADA for their personal accounts, potentially taking positions opposite to those of the Trust, subject to internal trading policies.
• The Sponsor purchased 10 Seed Shares from the Trust for $100 on October 15, 2025.
• There is an absence of arms-length negotiation with respect to some terms of the Trust, and no independent due diligence was conducted for the Trust's formation.

Stakeholder Impact

• **Shareholders**: Will gain indirect exposure to ADA, potentially benefiting from price appreciation and staking rewards (if enabled). However, they face significant risks from ADA price volatility, regulatory uncertainty, limited control over the Trust, and potential tax liabilities without corresponding distributions. The lack of in-kind redemptions could also impact liquidity and create premiums/discounts.
• **Authorized Participants**: Will facilitate the creation and redemption of Shares, benefiting from arbitrage opportunities. They bear operational risks related to cash orders and the inability to hedge ADA exposure, and may be deemed statutory underwriters.
• **Liquidity Providers**: Will facilitate the purchase and sale of ADA for cash orders, bearing price differential risks in Variable Fee Cash Orders.
• **Sponsor (Grayscale Investments Sponsors, LLC)**: Will manage the Trust, receive the Sponsor's Fee (and potentially a Staking Portion), and cover most ordinary expenses. Faces potential conflicts of interest due to its affiliations and other business ventures.
• **Custodian and Prime Broker (Coinbase entities)**: Provide critical custody and prime brokerage services, receiving fees from the Sponsor. They are subject to liability limitations and potential insolvency risks, which could impact the Trust's assets.
• **Cardano Network/Ecosystem**: The ETF's launch could increase institutional demand for ADA, potentially boosting its price and adoption. Conversely, negative regulatory actions or network vulnerabilities could adversely affect ADA's value and the network's reputation.
• **Regulatory Bodies**: The filing highlights ongoing scrutiny and the evolving regulatory landscape for digital assets, indicating continued engagement and potential new rules impacting the Trust and the broader industry.

Next Steps

• The Trust intends to list its Shares on NYSE Arca under the symbol GADA.
• NYSE Arca may seek 'In-Kind Regulatory Approval' to permit the Trust to create and redeem Shares through in-kind transactions.
• The Sponsor expects to implement a staking policy with respect to the Trust, describing the frequency and conditions of distributions, prior to the effectiveness of this registration statement and the listing of shares on NYSE Arca, and before engaging in Staking.
• The Cardano Network's 'Voltaire' phase is expected to introduce a formal process for ADA holders to propose and vote on Cardano Improvement Proposals and distributions from the Cardano Treasury.
• The SEC's Crypto Task Force and 'Project Crypto' will continue efforts to develop a comprehensive and clear regulatory framework for digital assets.
• The CFTC's 'crypto sprint' initiative will begin implementing recommendations for trading spot crypto asset contracts on CFTC-registered futures exchanges.
