XRP, Solana ETFs Lead Altcoin Inflows as Demand Expands Beyond Bitcoin

U.S.-listed spot altcoin ETFs continued to attract fresh capital on Tuesday, led by XRP (XRP) and Solana (SOL), signaling persistent—if selective—risk appetite beyond Bitcoin (BTC) and Ethereum (ETH). The flow data also showed steady demand for Chainlink (LINK), extending a multi-day streak of inflows.

According to SoSoValue, U.S. spot XRP ETFs posted net inflows of $17.11 million on April 15 (U.S. time), marking the fourth consecutive trading day of positive flows since April 10. Inflows were spread across four of the five products: Bitwise’s XRP ETF brought in $6.23 million, 21Shares’ TOXR added $5.43 million, Franklin’s XRPZ drew $5.30 million, and Canary’s XRPC contributed $0.14 million, while the remaining fund was flat.

Aggregate metrics for the XRP spot ETF category showed cumulative net inflows of $1.25 billion, daily trading value of $40.06 million, and total net assets of $1.02 billion—equivalent to roughly 1.19% of XRP’s market capitalization. The concentration of inflows across multiple issuers suggested broad-based allocation rather than a one-off spike tied to a single product.

Solana spot ETFs also extended their momentum, recording $5.36 million in net inflows—its second straight day of additions following $1.27 million in the prior session. Among the eight listed Solana ETFs, three products accounted for the day’s net buying: Bitwise’s BSOL pulled in $3.21 million, Fidelity’s FSOL gained $1.52 million, and Grayscale’s GSOL added about $0.64 million. The rest posted no material change.

For the Solana spot ETF segment overall, cumulative net inflows reached $981.32 million. Daily trading value totaled $53.42 million, while total net assets stood at $835.43 million—about 1.71% of SOL’s market capitalization. The relatively higher share of market cap represented by ETF holdings compared with XRP points to a more pronounced footprint in SOL’s investable float, even as daily inflows remained modest in absolute terms.

Elsewhere, Dogecoin (DOGE) spot ETFs were flat on the day after recording a small inflow of roughly $187,310 in the previous session. The category’s cumulative net inflows were reported at $9.17 million, with daily trading value of about $0.50 million and total net assets around $11.16 million—roughly 0.08% of DOGE’s market capitalization, underscoring its still-limited institutional penetration via ETFs.

Chainlink spot ETFs added $165,550 in net inflows, extending a five-session winning streak. SoSoValue data indicated the inflow came from Grayscale’s GLNK, one of two listed LINK spot ETFs. Cumulative net inflows for the segment rose to $101.75 million, with $2.73 million in daily trading value and $97.42 million in total net assets—about 1.44% of LINK’s market capitalization.

In contrast, Avalanche (AVAX) spot ETFs remained stagnant, with flows unchanged for a 20th consecutive trading day. The segment’s cumulative net inflows were $9.76 million, daily trading value about $122,740, and total net assets $17.54 million—around 0.43% of AVAX’s market cap.

Several smaller spot altcoin ETF categories also showed little movement. Canary’s Litecoin spot ETF (LTCC) was flat for a third straight session, with cumulative net inflows of $9.24 million and total net assets of $5.96 million. Canary’s Hedera spot ETF (HBAR) likewise stayed unchanged for three sessions, with cumulative net inflows of $94.86 million and total net assets of $50.32 million. 21Shares’ Polkadot spot ETF (TDOT) was flat for a second session, with cumulative net inflows of $1.91 million and total net assets of $10.64 million.

Overall, the day’s figures reinforced a market narrative in which ETF demand is broadening beyond major assets, but capital remains concentrated in a handful of liquid, institutionally familiar names. Sustained multi-day inflows into XRP, SOL, and LINK suggest that investors are treating certain altcoin exposures as strategic allocations rather than short-term trades, while the flat readings across other categories point to a more cautious approach to the long tail of the market.
