Ripple reported $2,395.6 million in circulating RLUSD as of September 3, 2026, a figure commonly rounded to $2.4 billion. The disclosure establishes the token’s outstanding supply on that date but does not say when circulation first crossed the threshold. Ripple separately reported $2,517.7 million in RLUSD reserve funds. RLUSD is designed to maintain a value of one U.S. dollar, backed by segregated cash and cash-equivalent reserves and redeemable 1:1 for dollars. DeFiLlama later showed roughly 2.42 billion RLUSD in circulation as of September 12, with a market capitalization near $2.42 billion, a price of $0.999968 and 24-hour volume of about $92.6 million. Those measures are not interchangeable: circulation is outstanding supply, market capitalization reflects the near-dollar value of that supply, and volume measures turnover over time. The September 12 snapshot showed about 1.37 billion RLUSD on Ethereum and roughly 1.05 billion on the XRP Ledger, which Ripple identifies as the token’s native issuance networks. Higher circulation confirms more tokens issued, but not necessarily greater usage, payments activity or institutional demand. Ripple says it publishes monthly independent third-party attestations covering circulating supply and backing assets. Standard Custody, an NYDFS-chartered and supervised limited purpose trust company, issues RLUSD, making its next attestation a key document to monitor. Related developments include Ripple Mint, which lets institutions mint and manage RLUSD through a user interface and API, and Ripple’s broader infrastructure expansion, including a $1 billion treasury platform augmented with AI agents and $275 million in senior notes for prime brokerage. The market-wide Fear & Greed Index stood at 63, or "Greed," on September 12, 2026, but that is a general risk gauge rather than an RLUSD-specific demand measure.
