U.S. spot XRP ETFs have now recorded 10 consecutive weeks of net inflows, extending a sustained period of positive capital flows into the investment products.
For the week ending September 18, XRP ETFs recorded approximately $9.57 million in net inflows, taking cumulative net inflows to about $1.71 billion. The latest weekly figure was lower than the $18.98 million recorded for the previous week, showing that the pace of new capital entering the funds has moderated.
The latest figures come as XRP ETFs continue to expand in both assets and trading activity.
XRP ETF Trading Volume Reaches $5.81 Billion
A recent Coinpedia research report puts cumulative trading volume across the seven U.S. spot XRP ETFs at approximately $5.81 billion, up from around $4.57 billion in August. The funds generated approximately $723 million in trading volume during August, marking a monthly record.
Trading volume and net inflows measure different aspects of the market. Trading volume represents the value of ETF shares changing hands, while net inflows measure capital entering the funds after accounting for redemptions.
That distinction is important. The $5.81 billion trading-volume figure should not be interpreted as $5.81 billion of new investment into XRP ETFs. The cumulative net-inflow figure is approximately $1.71 billion.
September Flows Show a More Mixed Picture
The latest daily data shows that ETF demand has become less consistent.
XRP ETFs recorded approximately $11.26 million in net inflows on September 14, followed by no reported net flow on September 15 and approximately $3.5 million in inflows on September 16. The sector then recorded roughly $5.15 million in net outflows on September 17 and another smaller outflow of approximately $43,700 on September 18.
For the full week, the funds still recorded approximately $9.57 million in net inflows.
The issuer-level data was also mixed. Bitwise recorded approximately $9.69 million in weekly inflows, while Franklin Templeton recorded about $5.02 million. 21Shares' XRP ETF recorded approximately $3.78 million in outflows.
August Remains the Strongest Period So Far
August represented a major acceleration in XRP ETF activity.
The seven U.S. spot XRP ETFs generated approximately $723 million in trading volume during the month. The increase in activity coincided with stronger XRP price performance and increased investor participation.
The week ending August 28 was also particularly significant, with XRP ETFs recording approximately $110.49 million in net inflows. That single week brought in more capital than the three subsequent weeks combined.
The contrast between August 28 and the latest weekly figure highlights how quickly ETF flow momentum can change even while the broader cumulative inflow trend remains positive.
ETF Holdings Represent More Than 1 Billion XRP
The dollar-based flow figures provide only part of the picture.
U.S. spot XRP ETFs represented approximately 1.1 billion XRP in holdings during September,

This figure represents XRP held by the funds and should not be described as XRP permanently removed from the market. ETF holdings can change through creations, redemptions and portfolio adjustments.
It is also different from net assets. The dollar value of ETF assets can change simply because the market price of XRP moves, even if the number of XRP held by the funds remains relatively stable.
Institutional Exposure Adds Another Layer
Institutional disclosures provide another measure of participation in the XRP ETF market.
Goldman Sachs reported approximately $87.4 million in XRP ETF exposure at the end of the second quarter of 2026, while Jane Street reported approximately $16.6 million and Millennium Management about $16.2 million, according to figures compiled in recent reporting.
A broader Bloomberg Intelligence compilation placed identified institutional XRP ETF exposure at approximately $183.5 million.

However, 13F filings should be interpreted carefully. They show reportable securities held at a particular quarter-end date, but they do not necessarily reveal whether a position was directional, hedged, connected to market-making activity or held on behalf of clients.
CLARITY Act Vote Adds Regulatory Uncertainty
The ETF market also entered a new regulatory environment in September.
On September 15, the U.S. Senate rejected a procedural motion to advance H.R. 3633, the Digital Asset Market CLARITY Act. The official Senate roll call recorded 49 votes in favor and 50 against, with one senator not voting.
The vote was a procedural vote on advancing the legislation rather than a final vote on the bill's substantive provisions.
The development nevertheless became an important part of the market backdrop for XRP and other digital assets because the legislation is intended to establish a federal regulatory framework for digital commodities and define responsibilities between U.S. financial regulators.
Federal Reserve Decision Adds a Macro Factor
The following day, September 16, the Federal Reserve raised the target range for the federal funds rate by 25 basis points to 3.75%–4.00%.
The Fed said economic activity was expanding at a solid pace while inflation remained elevated.
The timing was significant for crypto markets because the rate decision came only one day after the Senate's CLARITY Act vote. XRP ETF flows therefore developed against a backdrop of both regulatory uncertainty and changing monetary-policy expectations.
The data does not establish that either event directly caused the subsequent ETF flows, but both developments are relevant when assessing the market environment.
The Inflow Streak Is Continuing, but Momentum Has Slowed
The latest figures show a clear difference between cumulative demand and recent weekly momentum.
Cumulative XRP ETF net inflows remain around $1.71 billion, while cumulative trading volume has reached approximately $5.81 billion. At the same time, weekly inflows have declined from the $110.49 million peak recorded for the week ending August 28 to $18.98 million for the week ending September 11 and approximately $9.57 million for the week ending September 18.
This means the ETF market continues to attract net capital, but the pace has become considerably slower than during the strongest period in August.
What to Watch Next
The next phase of the XRP ETF market will depend on several separate indicators rather than a single headline figure.
Weekly net inflows will show whether fresh capital continues entering the funds. ETF-held XRP will indicate how much underlying exposure the products represent. Net assets will track the dollar value of those holdings, while trading volume will show how actively ETF shares are being traded.
Keeping these measurements separate provides a clearer picture of the market.
The XRP ETF sector has already accumulated approximately $1.71 billion in net inflows and nearly $5.81 billion in cumulative trading volume. The September slowdown does not erase that progress, but it does show that the strong August momentum is facing a different market environment.
The coming weeks will reveal whether the recent moderation is temporary or whether XRP ETFs are entering a slower phase after their strongest period of activity so far.
