XRP spot exchange-traded funds have now recorded 10 consecutive weeks of net inflows and reached a new all-time high for total cumulative net inflows, according to CryptoPotato. The same report puts Solana funds ahead on duration, with an inflow run that has stretched even longer than XRP's.
The headline is not one altcoin winning while another bleeds. It is two of the newer spot-ETF categories both pulling institutional money at the same time, with Solana setting the pace on how many weeks the streak has held.
Ten weeks of steady accumulation
The XRP figure that matters here is cumulative, not daily. A single strong week of inflows fades quickly from the tape. A record in total cumulative net inflows means that across the life of these products, more money has come in than at any prior point, and the last 10 weeks have added to that base without a single net-outflow week to break the run.
That kind of streak tends to reflect allocation decisions rather than short-term trading. Daily flows swing with price and sentiment. A multi-week run of positive weekly flows usually points to advisers and funds building positions on a schedule, not chasing a candle.
Price action has not moved in lockstep. XRP traded at $1.38 as of September 20, 2026, down 3.96% on the day and up 2.16% over the prior week, per CoinMarketCap. The ETF cash arrived while the spot token slipped on the session, a reminder that fund inflows and daily price can point in opposite directions over short windows.
Solana's run stretches further
CryptoPotato frames Solana as the standout on streak length. Solana spot funds have posted an even longer stretch of inflows than XRP's 10 weeks, which puts the two categories in the same trade rather than on opposite sides of it.
Solana traded at $108.30 as of September 20, 2026, down 3.1% on the day and up 7.6% over the prior seven days, again per CoinMarketCap. As with XRP, the token gave back ground on the session even as the fund category kept drawing capital over the longer window.
Weekly flow data for Solana funds has been choppy at the daily level through September, with individual sessions swinging between small inflows and small outflows. The longer streak CryptoPotato cites is a weekly measure, which smooths out those daily reversals. That distinction matters: a run can look unbroken on a weekly chart while still showing red days inside it.
The rotation read, with limits
Institutional flow into XRP and Solana products lands against a backdrop where Bitcoin and Ether funds have seen heavier outflow days this month. Read narrowly, that looks like rotation: capital trimming the two largest assets and adding to the next tier of single-asset ETFs. Read cautiously, it is early. These altcoin ETF categories are young, their asset bases are small next to the Bitcoin funds, and a few large tickets can swing a weekly number.
The broader market is still leaning risk-on. The Crypto Fear & Greed Index sat at 71, in "Greed" territory, as of September 20, 2026. Bitcoin held $80,721, down about 1% on the day but up 4.63% on the week. Sentiment at that level tends to support inflows into newer, higher-beta products like single-asset altcoin ETFs, which cuts both ways: it can reverse as fast as it built if the mood turns.
For anyone holding XRP or SOL directly, the takeaway is narrow. Sustained ETF inflows widen the pool of buyers who can access these assets through regulated wrappers, which can support liquidity over time. It does not set a price floor, and this week's data showed both tokens falling on the day the inflow story ran.
Overview
XRP spot ETFs have logged 10 straight weeks of net inflows and a record cumulative net-inflow total, while Solana funds have posted an even longer streak, per CryptoPotato. Both token prices fell on the session anyway, with XRP at $1.38 and SOL at $108.30 as of September 20, 2026. The pattern reads as institutions funding two altcoin ETF categories at once rather than favoring one over the other, though the asset bases are small and weekly streaks can mask choppy daily flows. Treat the streak as an allocation signal, not a price guarantee.
