Grayscale Files Seven Altcoin ETFs in One Week, From Dogecoin to Decentralized AI

Grayscale Investments filed seven SEC amendments in one week for altcoin ETFs spanning DeFi, meme coins, decentralized AI, and privacy tokens — the most aggressive product push from any single crypto asset manager in 2026.

Between April 1 and April 7, Grayscale Investments quietly filed seven separate documents with the U.S. Securities and Exchange Commission, each one advancing a different altcoin exchange-traded fund toward listing or updating its registration. The filings cover XRP, Solana, Sui, Dogecoin, Chainlink, Bittensor, and Zcash — a lineup that spans nearly every corner of the crypto market, from established Layer 1 blockchains to a meme coin to a decentralized artificial intelligence network. For a single asset manager to advance seven products in one week is unusual even in traditional finance. In crypto, where regulatory clarity has been elusive for over a decade, it signals something larger: the altcoin ETF era has arrived.

What Grayscale Filed and Why It Matters

The seven filings break down into three categories. Five are post-effective amendments — routine updates to existing registrations for Grayscale XRP Trust ETF (GXRP), Grayscale Solana Staking ETF (GSOL), Grayscale Sui Staking ETF (GSUI), Grayscale Dogecoin Trust ETF (GDOG), and Grayscale Chainlink Trust ETF (GLNK). These amendments incorporate each fund’s annual report on Form 10-K filed in March 2026, a procedural step that keeps the continuous share issuance process running smoothly.

The sixth filing is an S-1 amendment for the Grayscale Bittensor Trust (GTAO), which would convert an existing over-the-counter trust into the first U.S.-listed exchange-traded product offering exposure to TAO, the native token of the Bittensor decentralized AI network. An S-1 amendment — as opposed to a routine post-effective update — means Grayscale is actively advancing a brand-new product through the SEC’s registration process. Bittensor currently trades near $307 with a market capitalization of approximately $3.3 billion.

The seventh is an S-3 amendment for the Grayscale Zcash Trust (ZCSH), which would list Zcash — a privacy-focused cryptocurrency — as an ETF on NYSE Arca. If approved, it would be the first U.S. ETF tracking a privacy coin, a category that has historically faced heightened regulatory scrutiny due to Zcash’s optional shielded transactions feature, which allows users to send funds without revealing transaction details on the public blockchain.

The Staking Revolution Inside Crypto ETFs

What makes several of these products different from earlier crypto ETFs like GBTC (Grayscale’s flagship Bitcoin fund) is staking — the process by which holders of certain cryptocurrencies lock up their tokens to help validate transactions on the network and earn rewards in return, similar to earning interest on a savings account. Four of Grayscale’s 15 total ETFs now include staking: the Ethereum Staking ETF (ETHE), Solana Staking ETF (GSOL), Sui Staking ETF (GSUI), and the Avalanche Staking ETF (GAVA), which launched on NASDAQ on March 12, 2026.

The staking model means investors don’t just get price exposure to a cryptocurrency — they also earn yield. GAVA, for example, can stake up to 70% of its Avalanche holdings, with rewards flowing directly to shareholders. GSUI retains 77% of gross staking rewards after Grayscale’s sponsor, custodian, and staking provider take a combined 23% fee. This transforms crypto ETFs from pure speculative instruments into yield-bearing products, a shift that makes them considerably more attractive to institutional investors and retirement fund managers who need income generation, not just capital appreciation.

The Regulatory Tailwind: SEC-CFTC Commodity Classification

None of this would be moving this fast without the landmark joint ruling issued on March 17, 2026, when the SEC and Commodity Futures Trading Commission formally classified 16 major cryptocurrencies — including Solana, XRP, Cardano, Chainlink, Avalanche, Dogecoin, and Litecoin — as digital commodities rather than securities. The classification, which came through a 68-page interpretive release and a “Project Crypto” coordination framework, effectively removed the primary legal barrier that had blocked altcoin ETF approvals for years.

Under the previous regulatory ambiguity, the SEC could argue that most altcoins were unregistered securities under the Howey test — a legal standard from a 1946 Supreme Court case that defines a security as an investment of money in a common enterprise with the expectation of profits derived from others’ efforts. With the commodity classification in place, altcoin ETFs now follow the same approval pathway as commodity-based products like gold ETFs. The SEC also approved accelerated listing standards that compress approval timelines from up to 240 days to as few as 75 days, and Bloomberg analysts now project 100% approval probability for all pending altcoin ETF filings.

Grayscale’s Position in the ETF Race

Grayscale now operates 15 ETFs with approximately $18 billion in total assets under management, making it the largest pure-play crypto asset manager in the United States. But the company faces increasing competition. BlackRock’s iShares division has filed for a Bitcoin Premium Income ETF that would use covered-call options strategies to generate yield. Bitwise filed for 11 single-token “strategy” ETFs in late 2025. VanEck, Fidelity, and Franklin Templeton all have active crypto ETF applications.

The competitive pressure is real. Grayscale’s flagship GBTC has seen $25 billion in outflows since converting from a closed-end trust to an ETF in January 2024, as investors rotated into lower-fee alternatives from BlackRock and Fidelity. By pushing aggressively into altcoins, staking products, and first-mover categories like decentralized AI and privacy coins, Grayscale is betting that breadth of product lineup — not just Bitcoin dominance — will define the next phase of the crypto ETF market.

What to Watch

Bittensor ETF Approval Timeline: The GTAO S-1 amendment filed April 2 moves this product closer to a potential listing. If approved, it would be the first ETF offering exposure to a decentralized AI protocol — a category that could attract significant interest given the broader AI investment boom. Watch for NYSE Arca’s 19b-4 filing to formally request listing.

Zcash Privacy Coin Precedent: A Zcash ETF approval would set a precedent for privacy-focused tokens, which regulators have historically viewed with suspicion. The outcome could determine whether other privacy coins like Monero ever get ETF treatment in the U.S.

Staking Yield Competition: As more ETFs add staking, watch for a fee war. Grayscale currently takes 23% of gross staking rewards on several products. Competitors offering lower staking fees could pull assets, similar to the Bitcoin ETF fee war that drained GBTC.
