Grayscale has filed a registration statement on Form S-1 for a proposed Hyperliquid exchange-traded fund, escalating a niche but fast-growing US altcoin ETF contest that already includes Bitwise and 21Shares. The move matters because Hyperliquid’s HYPE token has grown into a top-tier crypto asset by market value, while issuers are testing how far the Securities and Exchange Commission will let the spot-crypto ETF playbook expand beyond bitcoin and ether.
SEC search results available on March 21, 2026, show Bitwise filed its original S-1 for the Bitwise Hyperliquid ETF on September 25, 2025, while 21Shares filed its Hyperliquid ETF S-1 on October 29, 2025. Grayscale had previously registered Delaware statutory trusts tied to BNB and HYPE on January 8, 2026, a step often used before a federal securities filing. The new S-1 places Grayscale directly into the same product lane as Bitwise and 21Shares, according to SEC EDGAR records and Delaware trust records surfaced in market coverage.

March 21 Filing Adds a Third US Issuer to HYPE ETF Queue
The core story is institutional. Hyperliquid is no longer being treated only as a DeFi trading venue; it is now being packaged for the US ETF market by three separate issuers. Bitwise’s filing describes a trust designed to hold Hyperliquid directly and calculate NAV using a benchmark set at 4:00 p.m. Eastern time. 21Shares’ filing similarly proposes direct HYPE exposure and names Coinbase Custody Trust Company and BitGo Trust Company as custodians.
That matters because product design is converging around the same institutional stack already familiar from earlier crypto ETFs: a trust wrapper, third-party custody, benchmark-based NAV calculation, and exchange listing subject to a separate rule-change process. In other words, the HYPE ETF race is not just about one token. It is a test of whether the SEC and exchanges will extend the spot-crypto ETF model deeper into altcoins with shorter operating histories and more concentrated ecosystem risk.
ℹ️
Grayscale’s January 8, 2026 Delaware HYPE trust was an early signal.
That trust registration did not itself create an ETF, but it indicated Grayscale was preparing the legal structure often used before an SEC registration statement. Sources reviewed March 21, 2026 linked that step to a potential future S-1.
$39 HYPE Price and $8.6B-$9.3B Market Cap Raise the Stakes
Hyperliquid’s market footprint helps explain why issuers are moving now. Web finance data on March 21, 2026, showed HYPE at $39.39, with an intraday range of $38.50 to $40.72. CoinGecko data crawled last week showed a market capitalization near $8.58 billion with roughly 240 million HYPE in circulation, while CoinMarketCap showed a higher market cap estimate of about $9.27 billion and circulating supply of 257.4 million. The gap reflects methodology and supply-count differences, but both sources place HYPE among the larger crypto assets by value.
There is also historical context. CoinGecko lists HYPE’s all-time high at $59.30 on September 18, 2025, which means the token remains well below that peak even after recovering into the high-$30 range by March 21, 2026. CoinMarketCap reported 24-hour spot volume above $420 million, indicating enough secondary-market activity for ETF sponsors to argue that price discovery is not trivial or illiquid.
Key Dates Behind the HYPE ETF Push
September 18, 2025: CoinGecko records HYPE’s all-time high at $59.30, giving issuers a reference point for investor demand and volatility.
September 25, 2025: Bitwise files its initial S-1 for a Hyperliquid ETF with the SEC.
October 29, 2025: 21Shares files its own Hyperliquid ETF S-1.
January 8, 2026: Grayscale forms a Delaware HYPE trust, signaling product preparation.
March 21, 2026: Grayscale’s S-1 filing for a proposed Hyperliquid ETF is reported, turning preparation into a formal SEC registration step.
Why Hyperliquid, Not Another Smaller Altcoin, Triggered ETF Competition
Hyperliquid has a clearer institutional narrative than many newer tokens. The network is tied to one of crypto’s largest on-chain perpetual futures venues, and SEC filing language from Bitwise and 21Shares frames HYPE as the native asset of the Hyperliquid network rather than a meme-driven token. That distinction does not remove regulatory risk, but it gives issuers a stronger case that the asset has a functional ecosystem, measurable trading activity, and a benchmarkable market.
Still, the filings themselves underline the risks. Bitwise’s S-1 warns that any SEC or state action asserting Hyperliquid is a security could materially hurt the token price and the ETF shares. Another SEC filing tied to a separate HYPE-linked product warns that the permissionless environment can be susceptible to manipulation, front-running, flash-loan attacks, and exploitative trading behavior. Those disclosures are standard in one sense, but they are especially important for an asset whose trading identity is rooted in DeFi derivatives.
How the Three HYPE ETF Efforts Compare
| Issuer | Known filing date | Structure signal | Custody details disclosed |
|---|---|---|---|
| Bitwise | September 25, 2025 | Direct-holding trust | Coinbase Custody named in S-1 |
| 21Shares | October 29, 2025 | Direct-holding trust | Coinbase Custody and BitGo named in S-1 |
| Grayscale | March 21, 2026 reported S-1 | Follows January Delaware trust setup | Full filing details still being parsed |

Three Paths Now Depend on SEC Review and Exchange Filings
An S-1 alone does not put an ETF on the market. For spot crypto ETFs, issuers also need an exchange listing proposal, typically through a 19b-4 filing by the exchange, followed by SEC review. That means Grayscale joining the queue increases competitive pressure, but it does not establish a launch date. The practical next step is whether an exchange files to list the product and whether the SEC engages with amendments, comments, or delays.
For investors, the significance is broader than HYPE. If the SEC eventually permits a Hyperliquid ETF, it would strengthen the case that US-listed spot crypto ETPs can extend to assets outside the first wave of bitcoin and ether and beyond the next tier of larger smart-contract tokens. If the agency resists, the filings still provide a map of where issuers believe demand exists in 2026.
Frequently Asked Questions
What did Grayscale file for Hyperliquid?
Grayscale filed a registration statement on Form S-1 for a proposed Hyperliquid ETF, according to market reports on March 21, 2026. An S-1 is the SEC registration document used to describe the fund’s structure, risks, and operations before any public launch.
Who else has filed for a Hyperliquid ETF in the US?
Bitwise filed its Hyperliquid ETF S-1 on September 25, 2025, and 21Shares filed its Hyperliquid ETF S-1 on October 29, 2025, according to SEC EDGAR records. Grayscale is therefore the third known issuer in the US HYPE ETF race.
Does an S-1 mean the Hyperliquid ETF is approved?
No. An S-1 is only one part of the process. A crypto ETF also typically needs an exchange rule-change filing, usually a 19b-4, plus SEC review of both the registration and listing path before trading can begin.
Why are issuers interested in HYPE now?
As of March 21, 2026, HYPE traded near $39.39 by web finance data, while CoinGecko and CoinMarketCap placed its market capitalization in roughly the $8.6 billion to $9.3 billion range. That scale, combined with heavy trading activity and Hyperliquid’s role in on-chain perpetuals, gives issuers a stronger institutional demand case than many smaller altcoins.
What is the main regulatory risk for a Hyperliquid ETF?
The filings themselves highlight that if the SEC or a court were to determine Hyperliquid is a security, the token price and any ETF shares could be materially affected. Other disclosed risks include market manipulation and exploitative trading behavior in permissionless crypto markets.
