Visa, Mastercard, Stripe, and Coinbase Commit $1 Billion to New Stablecoin: Is Open USD a Challenge to Tether, USDC, and RLUSD?

Visa, Mastercard, Stripe, and Coinbase just pooled $1 billion behind a brand-new stablecoin that shares its profits with partners rather than hoarding them, and that single design choice puts one established giant directly in the crosshairs.

Coinbase (NASDAQ: COIN | COIN Price Prediction), Mastercard (NYSE: MA), Visa (NYSE: V), Stripe, and Shopify have collectively committed $1 billion in liquidity to the Open USD stablecoin, which launched on September 30, 2026. A stablecoin is designed to maintain a value of $1, and with major payment companies backing it, OUSD is entering the market with significant support.

The $1 billion represents liquidity that these partners are ready to provide, allowing users to easily convert OUSD into dollars. While this commitment is substantial, it still pales in comparison to the existing market giants. This raises the question: Does Open USD pose a threat to Tether (CRYPTO: USDT), USD Coin (CRYPTO: USDC), and Ripple’s RLUSD (CRYPTO: RLUSD)?
