Ripple’s RLUSD stablecoin reportedly reached a new all-time high in circulating supply this week, although the precise figure remains disputed. At the same time, claims that spot XRP exchange-traded funds (ETFs) are absorbing large amounts of capital lack the fund-level and period-specific data needed to verify them.

DeFiLlama’s daily history records a peak on September 9, 2026, followed by a decline. That reading represents a daily-history high rather than an independently confirmed intraday maximum. A widely circulated figure of $2.442 billion has not been matched to a dated original source.

The available evidence also does not establish that ETF activity caused RLUSD issuance. Similarly, a record in stablecoin supply does not, by itself, demonstrate increased demand for XRP.

What the RLUSD Record Measures

RLUSD is Ripple’s US dollar stablecoin. Ripple says the token is natively issued on both the XRP Ledger and Ethereum, backed by segregated cash and cash-equivalent reserves, and redeemable 1:1 for US dollars. Ripple’s transparency disclosures listed circulating RLUSD of $2,395.6 million against reserve funds of $2,517.7 million as of September 3, 2026.

The reported milestone concerns supply rather than price. Because a dollar stablecoin is designed to remain near $1, an “all-time high” in this context refers to the number of tokens in circulation.

According to DeFiLlama’s RLUSD data, the highest observation was 2,441,344,797 RLUSD on September 9, 2026. It was the maximum among 733 daily readings dating back to August 23, 2024, rather than a verified intraday peak.

The separate $2.442 billion figure has circulated alongside the headline, but available reporting has not tied that exact amount to a dated original statement. The supply is also distributed across more than one blockchain. A DeFiLlama list snapshot assigns approximately 1.37 billion RLUSD to Ethereum and roughly 1.05 billion to the XRP Ledger. The total therefore should not be described as residing entirely on XRPL.

What Is Known About Spot XRP ETF Inflows

The headline describes spot XRP ETFs as “soaking up huge amounts of capital,” but the available evidence does not identify the funds, jurisdictions, reporting period or net-flow totals behind that characterization. As a result, the statement remains a claim rather than a documented measurement.

A substantiated assessment would require a defined reporting window and sourced net-flow data. Those figures would also need to be distinguished from raw trading volume and total assets under management, which are separate metrics and are often conflated.

The broader competition among issuers, including reports that Ripple’s XRP ETF momentum led the September crypto ETF field, provides context but not a dated flow figure. Without fund-specific data, it would be premature to infer the types of investors involved, direct purchases of XRP or any effect on the token’s price.

The RLUSD supply record and the ETF inflow claim are therefore best assessed separately until a shared, dated dataset establishes a connection between them.

Ripple, RLUSD and XRP Are Separate Components

Three distinct elements are involved: Ripple the company, RLUSD the stablecoin and XRP the cryptoasset. Ripple’s June 2025 material identifies XRP as the XRP Ledger’s native asset, used for liquidity and transaction fees. RLUSD is one of several stablecoins operating on the ledger. That distinction is important when interpreting a stablecoin supply record.

An increase in the amount of a stablecoin in circulation indicates demand for on-chain dollars, but it does not necessarily indicate demand for XRP itself.

Ripple says RLUSD is issued by Standard Custody, which it describes as a limited-purpose trust company chartered and supervised by the New York State Department of Financial Services (NYDFS). Ripple also says the token is backed 100% by highly liquid short-term reserves and supported by monthly independent attestations, according to its RLUSD product page. These statements are attributed to Ripple; the regulator’s own records were not independently reviewed.

Sustained RLUSD growth across Ethereum and XRPL could indicate expanding on-chain use. Other infrastructure developments, such as Ripple’s native lending protocol reaching the XRPL testnet, could also support broader on-chain activity over time. Ripple’s separately reported $2.4 billion XRP buyback plan is another data point cited by ecosystem supporters.

However, the same dataset also shows that the record did not hold. DeFiLlama’s September 14, 2026 daily reading put RLUSD supply at approximately 2,422,747,371, below the September 9 peak.

XRP’s spot market was subdued in the fetched snapshot. The token traded near $1.38, with a 0.9% daily move and an $86.5 billion market capitalization. The data did not show the type of trading profile that would independently confirm an ETF-driven buying surge.

The crypto-wide Fear \u0026 Greed Index stood at 57, classified as “Greed,” on September 14, 2026. That gauge measures broader crypto-market mood and is not specific to XRP. The index is published by Alternative.me.

Assessing the RLUSD and ETF developments together would require a single dated stablecoin metric and comparable, sourced ETF net-flow figures covering the same period. Until that information is available, any implications for liquidity, adoption or investor demand remain conditional. The fact that the two claims appear together does not establish a mechanism linking them.
