AI and Stablecoins Reshape Payments: How Stripe, Adyen, Visa, and PayPal Are Positioning

The payments industry spent 2025 quietly rearranging itself around two forces - AI agents that need to move money, and stablecoins that can move it cheaply. By the end of the year, Stripe had paid $1.1 billion for Bridge, Mastercard and Coinbase had launched a stablecoin enterprise service, and PayPal had expanded its PYUSD rails. Visa is still studying the field. The strategic map for the next decade is now visible.

Stripe's Bridge Bet

Stripe's $1.1 billion acquisition of Bridge in November 2025 was the clearest signal that the company intends to own the stablecoin-enterprise layer. Bridge's API now powers stablecoin issuance and redemption for several Fortune 500 merchants, with Stripe sitting in the middle as the orchestration layer.

"Stablecoins are not a crypto product. They are a payments product that happens to use crypto rails. Stripe is building the product layer; the underlying chain is plumbing," said a payments-industry analyst.

Mastercard and Coinbase's Joint Play

Mastercard and Coinbase have built a stablecoin-enterprise service aimed at corporate treasury, B2B settlement, and cross-border payouts. The combination brings Mastercard's bank-rail reach and Coinbase's on-chain infrastructure to a market that neither could serve alone.

Visa's Watchful Waiting

Visa has not publicly committed to an acquisition target in the stablecoin space. The company did enable stablecoin settlement for cross-border B2B payments across 12 corridors earlier this year and has signaled that it will integrate regulated stablecoins into its existing network as the regulatory picture clears.

Adyen and PayPal's Different Bets

Adyen has leaned into AI-driven merchant-side automation - dynamic routing, fraud detection, and agent-based checkout flows - rather than stablecoin issuance. PayPal has expanded PYUSD and is now piloting stablecoin payouts for marketplace merchants. Both are betting that the merchant-experience layer matters more than the underlying rail.

The four-way race for the AI-and-stablecoin payments stack is now a question of who controls the orchestration - and increasingly, the answer is Stripe.
