Summary
- Bitwise BHYP ETF recorded $19.05M single-day inflow on May 15 launch becoming largest Hyperliquid ETF
- Spot XRP ETFs reached $1.41B cumulative inflows since Nov 2025 launch with $60.5M weekly record ending May 15
- Bitcoin and Ethereum ETFs saw combined outflows of $1.64B since May 2026 began
Bitwise's BHYP ETF posted a record $19.05 million single-day inflow on May 15 2026. The move made it the world's largest Hyperliquid ETF by assets. This inflow arrived as spot XRP ETFs added another $60.5 million that same week.
The surge underscores fresh institutional demand for altcoins beyond Bitcoin and Ether.
Cumulative XRP ETF inflows now stand at $1.41 billion since their November 2025 debut. Bitcoin and Ethereum ETFs posted $1.64 billion in net outflows for the month to date.
Context
Altcoin ETFs launched later than their Bitcoin and Ether counterparts. XRP products began trading in late 2025 while Hyperliquid vehicles arrived in 2026. May data shows these newer products capturing flows that legacy crypto ETFs are losing.
Bitwise has positioned its BHYP vehicle as a pure-play vehicle for HYPE token exposure. The firm reported $19.05 million in fresh capital on launch day alone.
That single print lifted the product's total inflows past rival Hyperliquid ETFs.
"Bitwise's BHYP sees record $19M inflow as HYPE ETFs lead altcoin demand, outpacing Bitcoin and Ether by market-cap-adjusted demand today."

Details
On-chain data confirmed the May 15 inflow figure. Bitwise CEO Hunter Horsley noted the daily total lifted cumulative BHYP inflows to new highs. The product quickly claimed the largest market share among Hyperliquid-focused ETFs.
XRP ETFs extended their longest inflow streak of 2026 through the same period. Weekly additions reached $60.5 million for the week ending May 15.
Total assets under management across these products now exceed $1.12 billion.
Bitcoin and Ethereum ETFs moved in the opposite direction. Net redemptions reached $1.64 billion across the two asset classes in the first half of May alone. This divergence marks the clearest sign yet of institutional rotation into altcoin vehicles.
One risk remains for the HYPE bull case despite the $19M inflow. Spot ETF holdings now represent 1.04 percent of HYPE market cap while trading volume has risen 44 percent to roughly $1 billion.
Observers continue to monitor whether these flows can sustain without broader market confirmation.

Record inflow into HYPE ETF signals altcoin season. (https://x.com/example/status/123)
Institutional desks have increased allocations to products that offer direct altcoin exposure. Trading desks report higher block sizes in HYPE and XRP ETF shares compared with prior months.
The pattern aligns with earlier rotation signals observed in Solana and other large-cap altcoins.
The Bitwise HYPE ETF and parallel XRP products now sit at the center of this shift. Their combined inflows contrast sharply with the outflows from Bitcoin and Ether vehicles. Market participants view the data as evidence that altcoin adoption has moved beyond retail channels.
Bitwise plans to release updated holdings data for BHYP in coming weeks. XRP ETF issuers will publish their next weekly flow reports shortly after.
These releases will show whether the May momentum continues into June.
