US-listed crypto ETFs tracking tokens beyond Bitcoin and Ethereum attracted nearly $90 million in net inflows during the week ended August 21, driven by double-digit price rallies and a White House push for regulatory clarity.

XRP led the inflows with $39.78 million, extending a six-week streak of positive weekly flows. The token climbed from below $1 to as high as $1.60 during the week, gaining roughly 50 percent before retreating to $1.49 at press time. XRP ETF products have accumulated $1.55 billion in net inflows since launch, according to data from SoSoValue.

Solana ETF funds received $28.34 million, marking their eighth consecutive week of positive inflows. SOL jumped approximately 24 percent and briefly traded above $100 for the first time since February, then slipped to around $93. Solana ETF products have drawn $1.19 billion cumulatively.

Chainlink ETF funds recorded their strongest resurgence since launch with $13.35 million in weekly inflows. LINK gained about 22 percent during the week, touching $12 for the first time since January before retreating to $11.40.

Hyperliquid ETF products attracted $3.89 million for a third consecutive positive week. HYPE hit a record of roughly $82 during the week before easing to $79 at press time. Hyperliquid ETF assets under management stand at $350 million, with cumulative net inflows of $287 million since launch.

Smaller altcoin ETFs also saw inflows: Avalanche received $1.3 million, Hedera $848,000, and Dogecoin $654,416.

Regulatory tailwinds

On August 19, President Donald Trump held a White House meeting with crypto executives to highlight efforts to establish a legal route for Hyperliquid to operate in the US. Trump urged Congress to advance crypto market-structure legislation during the meeting, according to CryptoSlate reporting.

The altcoin inflows occurred alongside a strong week for flagship crypto assets. Bitcoin and Ethereum ETF products combined to attract $2.61 billion, marking their strongest week since October 2025 and their best week of 2026. Bitcoin ETF inflows alone totaled $1.92 billion, while Ethereum ETF products drew $697 million.

Despite the headline figure, altcoin ETF inflows remain small relative to Bitcoin and Ethereum ETF inflows, underscoring the concentration of institutional capital in the two largest cryptocurrencies by market capitalization.
