Grayscale filed a 424B3 prospectus supplement for its Hyperliquid Staking ETF on June 24, registering new shares for a fund already trading on Nasdaq as HYPG since June 3. A 424B3 supplements an already-effective registration; HYPG carries a 0.29% sponsor fee, the lowest stated rate among the three US spot HYPE products.

Three US-listed products tracking the HYPE token now compete in a market that opened six weeks ago. 21Shares' THYP launched on Nasdaq on May 12 at 0.30%. Bitwise' BHYP opened on NYSE Arca on May 15 at 0.34%, with the first month at 0%.

Combined net inflows into all three products reached $153M through June 16, with no net-outflow days since launch. The peak single-day total was $25.5M on May 20, per Crypto Briefing.

Hyperliquid's 30-day protocol revenue stands at $63.01M and 30-day fees at $79.77M per DefiLlama as of June 24, placing it above Ethereum in cross-chain revenue rankings. Hyperliquid routes 99% of trading fees into a fund that buys back HYPE tokens, tying protocol usage directly to token supply.

ETF inflows measure brokerage demand for HYPE exposure, not on-chain activity; the two can diverge.

Durable weekly inflows after BHYP's first-month fee waiver expires would confirm structural demand. A flow plateau at that date, or a reversal in Hyperliquid's protocol revenue, would suggest the opening rush was promotional-fee-driven, not fundamental.
