Open Standard's OUSD Tops Stablecoin Issuers With $794 Million Supply Gain

Open Standard's Open USD (OUSD) stablecoin added $794 million in 30-day supply, the largest gain of any stablecoin issuer, according to Token Terminal data reported by Crypto Briefing on October 28, 2026. OUSD went live on September 30, 2026, so the 30-day window covers almost the entire life of the token.

How OUSD Reached the Top of the Leaderboard

Open Standard launched OUSD simultaneously on Ethereum, Base, Solana and Tempo. At launch, its market cap sat at approximately $468 million to $477 million, and within the first week it climbed to around $668 million. By mid-October, OUSD had crossed $800 million, and DefiLlama data showed it at approximately $828 million by October 28, 2026.

The distribution across chains is lopsided. Approximately 64% of OUSD's supply, or more than $500 million, sits on the Tempo blockchain as of mid-to-late October. Tempo is backed by Stripe and other significant partners, and Stripe is one of OUSD's founding partners.

Open Standard positions OUSD as shared infrastructure for payments and programmable finance. Minting and redemption cost nothing, and users can swap OUSD for US dollars at a 1:1 ratio through partner platforms. Coinbase, Mastercard, Shopify, Stripe and Visa each hold equal equity stakes in the venture. Reserves backing OUSD are held at BlackRock, Lead Bank and BNY Mellon, and Open Standard publishes month-to-month reserve attestations. Initial commitments exceeded $1 billion in liquidity from a partner network of more than 200 companies.

Open Standard's Partner Consortium

Open Standard assembled a founding consortium of 140+ partner organizations at announcement, including Visa, Stripe, Mastercard, BlackRock, BNY, Coinbase, Shopify, and dozens of global banks and crypto-native firms, according to akta.pro company records. The same records show Stripe committed to make Open USD the default stablecoin for businesses on Stripe, anchored by Stripe President of Technology and Business Will Gaybrick. Open Standard, founded in 2020 and headquartered in Oakland, operates OUSD as a no-fee stablecoin and generates revenue through a small management fee on shared reserve economics.

SBI, Startale and the OUSD Buildout

In October 2026, SBI Holdings and Startale Group joined Open Standard to explore interoperability between OUSD and JPYSC stablecoins, aiming to make yen-dollar settlement faster and more efficient, The Paypers reported. In September 2026, Zach Abrams, co-founder of Bridge, was appointed full-time CEO of Open Standard, the company behind OUSD, Coingape reported. In August 2026, Dunamu, parent of South Korean exchange Upbit, announced a strategic partnership with Visa to explore stablecoin payments, cross-border remittances and AI-driven finance, with OUSD under consideration, The Block reported.
