Cumulative inflows into US spot XRP ETFs have stalled at $1.71 billion, leaving the products $290 million short of the $2 billion mark as weekly buying shrinks for a third straight week. Data from SoSoValue pulled on September 19 put the running total at $1,710,373,047, and the weekly net inflow for the period ending September 18 was just $9.57 million, the weakest showing since the products found their footing earlier this year.
The slowdown is now a pattern rather than a one-week dip. Net inflows came in at $13.32 million for the week ending September 4, $18.98 million the following week, and $9.57 million last week. August was a different story: the week ending August 28 brought a 2026 record of $110.49 million, when XRP traded near $1.38 after testing $1.70 earlier in the month. Total net assets across the seven US spot XRP ETFs stood at about $1.44 billion at that point, meaning the fund complex has added barely $50 million since.
Policy shock froze the tape
Two macro events bookended the stall. On September 15 the Senate rejected the CLARITY Act, the bill that would have set out how US regulators split oversight of digital assets between the SEC and the CFTC, by a vote of 49 to 50. Crypto ETFs shed roughly $592 million combined the next session, with bitcoin funds recording their largest single-day outflow of the year at $450 million and ether funds losing $142 million. Prediction markets had put 53% odds on the bill becoming law by mid-2027 after President Trump endorsed the revised 635-page Senate draft, so the failure landed harder than a routine procedural loss.
Then on September 16 a House committee approved the first federal crypto tax framework in a 38-5 vote, a partial offset that did little for XRP products specifically. The tax bill would give taxpayers relief on everyday crypto transactions and set holding-period rules that the industry has asked for since 2021, but it does not touch the market structure question that XRP fund investors care most about: which regulator watches the asset, and under what rules exchanges can list it.
Senator Kirsten Gillibrand told reporters the defeat was not the end and that Democrats remain committed to passing the bill, while JPMorgan analysts called the passage window extremely narrow but not fully dead. Meanwhile the SEC and CFTC signaled they would push their own market structure rules regardless of what Congress does, which cuts both ways for fund investors: regulation is coming, but nobody can say yet what shape it takes.
Analysts tracking the flows note that the question has shifted from how fast the $2 billion mark arrives to whether August was the peak for XRP fund demand altogether.
Price diverges from fund flows
The token itself is not following the ETF tape. XRP closed at $1.41 on September 19, up 3.45% on the week, which points to stronger activity among spot buyers than among fund investors. That gap matters because ETF creation is the channel through which institutional money has reached XRP since the spot products launched, and three weeks of shrinking creations suggest that channel is thinning rather than pausing. Retail-sized holders can buy the token directly on an exchange in minutes; advisors and funds allocated through vehicles generally cannot, so a stall in creations is a reasonably clean read on institutional appetite.
| Week ending | Net XRP ETF inflow |
|---|---|
| August 28, 2026 | $110.49 million (2026 record) |
| September 4, 2026 | $13.32 million |
| September 11, 2026 | $18.98 million |
| September 18, 2026 | $9.57 million |
The contrast with other altcoin funds is sharp. Solana ETFs logged a twelfth consecutive week of inflows last week, taking in $60.7 million, and Zcash funds drew $98.2 million in the same week, the largest inflow among 14 crypto products tracked. Grayscale’s Zcash trust alone accounted for 32.5% of all spot crypto ETF trading volume in that week, an extraordinary concentration for a fund that launched only in August. XRP funds, which led that table barely three weeks ago, now sit near the bottom of it.
Zcash’s run also reframes what investors want right now. Privacy, not payments, is the theme pulling money, and Paradigm this week described ZEC as a private complement to bitcoin in a note that coincided with ZEC hitting records above $1,550. XRP’s pitch has always been settlement and payments infrastructure, which is a harder sell in a tape where the regulatory question that would unlock bank adoption just failed in the Senate.
What would restart the flows
Traders are watching two things. The first is whether the House tax framework and any revived version of the market structure bill restore the policy clarity the failed Senate vote removed. The House bill faces an uncertain path in the Senate, and the calendar is not helping: the November midterms are less than two months away, and legislative time is about to disappear into campaign season.
The second is Ripple’s own treasury activity. Evernorth, the Ripple-backed XRP treasury firm, signed a $30 million convertible note with NH Investment & Securities ahead of its planned Nasdaq debut through a SPAC merger in the fourth quarter. The note is payable only if the merger closes, so it is a conditional bet on XRP treasury demand continuing, but it does put a named institutional buyer back in the narrative at a moment when fund flows have gone quiet.
At the current pace of under $10 million a week, the $2 billion cumulative mark is roughly half a year away. A return to August’s rate would close the gap in about three weeks. Neither outcome is locked in, and the fund complex that priced XRP as a 2026 institutional favorite is for now treading water, waiting on Washington to give it a reason to move again.
