Stablecoin infrastructure firms win payment companies one corridor or one card program at a time. They price the offer against what the buyer pays to prefund accounts, convert currency and wait for settlement. The head of payments or treasury owns the decision, and a live corridor with measured cost and settlement time is the proof that closes it.
Why are payment companies buying stablecoin rails now?
The largest networks have already bought or built theirs. Stripe closed its $1.1 billion acquisition of Bridge, a stablecoin API company, in February 2025 (TechCrunch, 5 February 2025). Mastercard agreed on 17 March 2026 to buy BVNK for up to $1.8 billion, including $300 million in contingent payments (BVNK, March 2026), and completed the deal on 3 August 2026 (The Block, 3 August 2026).
Visa reports more than 160 stablecoin-linked card programs live and stablecoin settlement above a $20 billion annualised run rate, up more than 15 times in a year (The Block, 8 September 2026; company-reported). In April 2026 the same figure was $7 billion, across nine supported chains (CoinDesk, 29 April 2026).
Real payment volume is still small next to total stablecoin transfers. Artemis surveyed 22 stablecoin payment companies and estimated 11 more. In August 2025 their payments ran at $122 billion a year, with business-to-business payments at $76 billion and card-linked payments at $18 billion (Artemis, October 2025). Artemis put that at about 1% of the $26 trillion in yearly on-chain stablecoin settlement.
So the open market for an independent infrastructure firm is the long list of payment companies that have no stablecoin layer of their own yet.
Which payment companies buy first?
The ones with a cash problem that stablecoins fix this quarter. Rank segments by how much money they hold idle today.
| Segment | Stablecoin job | Trigger to watch | Usual owner |
|---|---|---|---|
| Cross-border payout and remittance firms | Fund payouts without holding days of cash in each corridor | A new corridor, or a local banking partner that exits | Head of treasury |
| Card program managers | Settle card spend from stablecoin balances | A new stablecoin-linked card launch | Head of product or CFO |
| PSPs and merchant acquirers | Take stablecoins at checkout and pay merchants in local currency | Merchant requests in a new region | Head of payments product |
| Payroll and contractor platforms | Pay contractors in dollars where local currency is weak | Contractor growth in one country | Head of payments or CFO |
Start with one segment and one region. A payout firm in Latin America and a card program manager in Europe ask different questions, buy on different evidence and talk to different banks.
What does the buyer compare you against?
Three options, in this order: the bank wires and prefunded accounts they run today, a build of their own, and the stablecoin product of a card network or large PSP they already use. Your pitch has to beat the first on cost and the third on fit.
Prefunding is the cost most buyers can measure fastest. Use this method with their numbers:
- Take the average daily payout volume in one corridor.
- Multiply it by the days of prefunding the buyer holds there. That is the idle balance.
- Multiply the idle balance by the buyer's cost of capital. That is the yearly cost.
- Repeat with the buffer your settlement time allows. The gap is your value.
An illustration with made-up inputs: a firm that sends $1 million a day into a corridor and holds five days of prefunding keeps $5 million idle. At an 8% cost of capital, that costs $400,000 a year. If stablecoin settlement cuts the buffer to one day, the idle balance falls to $1 million and the cost to $80,000. Ask the buyer for their own three inputs on the first call and send the result back in writing.
How does the sale run, and who signs?
Four teams look at the deal, usually in this order.
- Payments engineering tests the API in a sandbox and runs a small live corridor.
- Compliance reviews your licences, sanctions screening, travel rule handling and the on-ramp and off-ramp partners in each country.
- The buyer's bank partner often reviews the flow too, because fiat still lands in an account it holds.
- Treasury signs off on liquidity at the off-ramp and on who holds the stablecoins overnight.
Send the compliance pack before anyone asks for it. A pilot that works in engineering can still wait weeks for a bank partner's review.
How do you find the accounts that are ready?
Watch for the triggers in the table, and filter hard. Our catalyst monitor logged 180 go-to-market job posts, 79 hiring surges and 34 fundraise headlines between 26 July and 7 October 2026, among 6,069 signals in total (our data, October 2026; the rest were X posts, TVL moves and DeFi listings). For payment companies, a treasury or payments operations hire and a corridor launch announcement carry the most weight. More on which signals hold up is in which buying signals predict a B2B purchase.
Then write to the owner with one corridor, one figure from their business and a request for 20 minutes. Infrastructure that sells to both sides of a network grows by becoming the default integration, as in how blockchain infrastructure protocols grow market share. We took FastLane from 10% to 75% market share that way before Chainlink acquired the engine.
Checklist before the first outreach
- Pick one segment and one region from the table.
- List corridors where you can show live settlement time and cost today.
- Build the prefunding calculation as a one-page sheet the buyer fills in.
- Prepare the compliance pack: licences, screening, ramp partners per country.
- Name the bank partner question before the buyer raises it.
- Track corridor launches and treasury hires at 30 to 50 target accounts.
