Wall Street asset managers Bitwise and 21Shares have initiated a competitive “volume war” in the altcoin ETF market, signaling a pivot by institutional investors toward digital assets beyond Bitcoin and Ether. On May 15, 2026, Bitwise’s BHYP, a Hyperliquid-linked ETF, launched with approximately $4.31 million in debut trading volume. This followed the May 12 launch of a similar product from 21Shares, known as THYP, which debuted on Nasdaq with $1.8 million in volume and $1.2 million in net inflows.
The aggressive race for trading volume reflects a strategic push by firms to secure liquidity and brokerage shelf space as altcoin products transition into regulated offerings. According to market data from NS3.AI, these two Hyperliquid-linked funds generated a combined opening-day volume of $6.11 million. This total nearly matched the aggregate first-day volume of the previous eight U.S. spot altcoin ETF launches seen earlier in 2026.
The institutional shift comes as traditional Bitcoin products face recent volatility. On May 13, 2026, U.S. spot Bitcoin ETFs recorded a $635 million single-day outflow, which was the largest since late January. BlackRock’s IBIT led these withdrawals, accounting for nearly half of the total. In contrast, investor sentiment remains active in specific altcoin sectors, with Solana-based funds appearing more resilient during the mid-May market pressure.
Bitwise and 21Shares capture early Hyperliquid market share
The debut of BHYP and THYP marks a significant moment for specialized crypto ETFs. Bitwise’s BHYP debut volume of $4.31 million established it as a primary contender in the Hyperliquid space, though it follows a broader trend of high-volume altcoin debuts. In October 2025, Bitwise’s Solana Staking ETF (BSOL) set a high benchmark, recording $56 million in turnover on its first day and $10 million within the first hour of trading alone.
Securing early volume is viewed as vital for attracting market-maker engagement and institutional legitimacy. As investors monitor price support levels for major altcoins, the availability of regulated ETFs provides a new channel for capital. A survey by the Alternative Investment Management Association (AIMA) and PwC found that 55% of hedge funds now have exposure to cryptocurrencies, up from 47% last year.
This increased participation is helping stabilize the 30-day average trading volume for altcoins, which began moving above the 365-day average as of May 15, 2026. This technical pattern historically aligns with periods of heightened market activity. While some assets struggle, the “volume war” highlights which managers can successfully transition crypto assets into the hands of traditional brokerage clients.
Solana ETFs resist broader market outflows in May
Solana products have showed unique strength amid recent digital asset volatility. Spot Solana ETFs attracted approximately $33 million in net inflows during the week leading up to May 9, 2026, including a $6.7 million surge on Thursday. Even on May 13, a day marked by heavy Bitcoin outflows and over $500 million in long liquidations across the derivatives market, Solana ETFs were the only ones to record inflows, pulling in $6 million.
Other altcoin ETFs have seen varied levels of success since their inception. In late October 2025, Canary Capital launched two products with mixed results; their HBAR ETF recorded $4 million in first-day volume, while their Litecoin ETF generated roughly $400,000. These figures underscore the competitive nature of the “land grab” where a few dominant assets capture the majority of institutional interest and trading turnover.
JPMorgan forecasts billions in crypto ETF inflows
The broader outlook for the sector remains tied to the sheer volume of pending applications. Currently, over 150 crypto ETF filings are awaiting regulatory decisions. Despite the recent “bleeding” of $1.26 billion from the 11 listed Bitcoin funds over the five trading days leading to May 15, JPMorgan still forecasts US$6 billion in total inflows into the crypto ETF market.
Institutional demand is becoming the primary driver for these assets as other sources of capital dry up. Corporate treasury buyers have reduced their purchase volumes by 80% compared to the previous month. This leaves regulated ETFs as the primary channel for demand, particularly for altcoins like Solana or Hedera that are and undergoing expanded filing reviews by major firms like Grayscale and VanEck.
As the competition intensifies, not all products are finding immediate success. For instance, spot XRP ETF products reportedly failed to attract any new net inflows on May 7, 2026. The coming months will likely see more asset managers like Grayscale prepare competing products, such as their rumored Hyperliquid funds, as they vie for dominance in Wall Street’s expanding digital asset portfolio.
