Marqeta (NASDAQ: MQ) and BVNK said on September 9, 2026 that they are partnering to deliver stablecoin-backed card capabilities to both crypto-native and non-crypto companies building on Marqeta's issuing platform.
The deal pairs a card issuer that processed nearly $400 billion in 2025 payment volume with a stablecoin infrastructure provider running more than $39 billion in annualized volume. It arrives one month after Mastercard closed its acquisition of BVNK, which turns a routine vendor integration into something closer to a network-level alignment.
This piece covers what was announced, the scale of the two companies involved, why the Mastercard connection is the part that matters, and what fintechs weighing a stablecoin card program should do with the information.
Key Takeaways
- Marqeta customers will be able to embed stablecoin wallets and stablecoin-backed cards through a single BVNK integration.
- BVNK provides the stablecoin rails; Marqeta keeps card issuance, acceptance, and bank and network relationships.
- BVNK has been part of Mastercard since August 2026, so the integration is also a path into further Mastercard capabilities.
- Marqeta, BVNK, and Mastercard all back Open USD, a proposed cross-network stablecoin standard.
- BVNK research from earlier in 2026 found 77% of surveyed crypto holders would open a stablecoin wallet inside their primary bank or fintech app.
As of 9 September 2026
Marqeta ~$400B annual payment volume (2025); BVNK $39B+ annualized volume; Marqeta certified in 40+ countries; BVNK live in 130+ countries. Cards run on Mastercard rails.
What Marqeta and BVNK Announced
The two companies announced the partnership at Stablecon in Washington DC. The stated goal is to let Marqeta's customers add stablecoin capabilities to wallets, cards, and everyday financial products without building or operating the stablecoin infrastructure themselves.
The division of labor is clean. BVNK supplies the infrastructure for moving and managing stablecoins alongside fiat currencies. Marqeta manages card issuance, acceptance, and its bank and network relationships. Cardholders end up with a standard payment card that spends digital dollars at any merchant that accepts Mastercard.
Marqeta said it chose BVNK's regulated platform specifically to accelerate delivery while keeping the compliance and operational standards its enterprise customers expect. That framing matters: this is positioned as an enterprise product, not a crypto-native novelty.
Anthony Peculic, Marqeta's Chief Strategy Officer, said the real question with stablecoins is "how you incorporate them into the infrastructure people and businesses already trust." Chris Harmse, BVNK's Co-Founder and Chief Business Officer, framed the goal as making the stablecoin layer "invisible" to developers, the same way card networks are today.
The Scale Numbers Operators Should Bookmark
Both companies put their volume on the record in the release. Marqeta's figure is audited annual payment volume; BVNK's is an annualized run rate, so the two aren't directly comparable, but together they set the ceiling for what this integration could carry.
| Metric | Figure | Source |
|---|---|---|
| Marqeta annual payment volume (2025) | Nearly $400B | Marqeta/BVNK release |
| BVNK annualized payment volume | $39B+ | Marqeta/BVNK release |
| Marqeta operating footprint | 40+ countries certified | Marqeta/BVNK release |
| BVNK operating footprint | 130+ countries | Marqeta/BVNK release |
| Crypto holders who'd open a stablecoin wallet via their bank/fintech app | 77% of surveyed | BVNK research, 2026 |
| BVNK ownership | Mastercard, since August 2026 | Marqeta/BVNK release |
BVNK's customer list, per its own boilerplate, includes Corpay, Worldpay, Deel, and Flywire. That's a cross-border payments and payroll roster, which lines up with where stablecoin card demand tends to concentrate.
How the Integration Works
The partnership is built so that Marqeta customers don't have to touch a blockchain directly.
A program using Marqeta's platform gets access to BVNK's stablecoin infrastructure through Marqeta's existing integration surface. BVNK handles custody, movement, and management of stablecoin balances alongside fiat. Marqeta attaches card credentials to those balances the same way it already does for fiat-funded programs.
At the point of sale, the merchant sees a standard Mastercard transaction. There is no merchant-side change and no requirement that the merchant accept crypto. The conversion from stablecoin to settlement currency happens behind the card, which is the same model most stablecoin card issuers have converged on.
The practical effect for a fintech is that adding a stablecoin balance to an existing card program becomes a configuration and compliance decision rather than an engineering project.
Why the Mastercard Connection Is the Real Story
On its face, this is an issuer-processor adding a stablecoin vendor. The reason it's more than that is where BVNK now sits.
Mastercard closed its acquisition of BVNK in August 2026. Mastercard is also one of Marqeta's major network partners. So this integration doesn't just connect Marqeta to a stablecoin provider; it connects Marqeta to a stablecoin provider that is already inside its primary network.
The release says Marqeta customers will get a path to additional Mastercard capabilities "through the same integration, rather than a separate build."
That's a meaningful structural advantage. Every other issuer-processor that wants to offer stablecoin cards on Mastercard rails has to bolt on a third-party stablecoin layer and then separately negotiate whatever Mastercard offers on top. Marqeta is getting both through one door.
It also sharpens the contrast with Visa. Stablecoin Insider reported earlier this month that Visa is running an RFP for a new stablecoin settlement partner after losing BVNK to Mastercard. Visa's own numbers show more than 160 stablecoin-linked card programs on its network and a $20B+ annualized settlement run rate, so Visa isn't behind on volume. But it's now rebuilding a piece of its stack that Mastercard just bought outright, and Marqeta is one of the first large issuers to plug into it.

Open USD: The Standards Play Underneath
The release also notes that Mastercard, Marqeta, and BVNK all support Open USD, described as a collaborative, transparent, global standard for stablecoins built to work across networks, providers, and use cases.
Details on Open USD's governance and technical scope are thin in the announcement. What it signals is that Mastercard is trying to assemble an ecosystem around a shared spec rather than a proprietary coin, and it's lining up its network partners behind it early.
Whether Open USD becomes the interoperability layer or one of several competing standards is an open question. What's clear is that the number of large payments names attached to it is growing, and Marqeta's participation puts a major issuer-processor on the list alongside the network and the infrastructure provider.
Where the Demand Is Coming From
BVNK's stated rationale for the partnership leans on its own 2026 survey: 77% of crypto holders surveyed said they would open a stablecoin wallet through their primary bank or fintech app if one were offered.
The important word is primary. The demand signal isn't for new crypto apps; it's for stablecoin functionality inside apps people already use. That is precisely Marqeta's customer base: fintechs, neobanks, and embedded-finance programs that already have distribution and want to add a stablecoin balance and a card on top of it without a blockchain team.
The release frames this as stablecoins becoming "another payments rail alongside cards and bank transfers." That's the same language Visa, Stripe, and the large banks have been using through 2026, and it reflects where the market has landed: stablecoins as a settlement and balance layer, with cards as the spend interface on top.
Stablecoin Insider's take: the product here is unremarkable (a stablecoin balance with a Mastercard attached, which several providers already offer). The distribution is what's new. Marqeta puts stablecoin cards in front of hundreds of existing programs through an integration they were likely going to do anyway, and Mastercard gets a large issuer wired into its BVNK stack within weeks of closing the deal. The named risk is concentration: programs that go this route are building stablecoin capability on a single network's owned infrastructure. Portability to Visa or another rail later will not be free.
What Operators Should Do Next
If you're a Marqeta customer, or evaluating issuer-processors for a stablecoin card program, three questions are worth answering now.
- Check whether your current program's economics change when settlement moves to stablecoins. Ask Marqeta what the pricing and settlement timing look like on the BVNK path versus your existing fiat flow.
- Decide how much you care about network optionality. Building on BVNK inside Mastercard is the fastest route to market on this stack, but it's a Mastercard route. If you run or plan to run Visa programs too, map what a dual-network stablecoin setup would cost.
- Watch what "additional Mastercard capabilities" turns out to mean. The release promises more through the same integration. Until those are named, treat the near-term product as stablecoin wallet plus card, not a full Mastercard stablecoin suite.
This doesn't matter much for programs with no international or crypto-adjacent user base. It matters a lot for cross-border fintechs, payroll and contractor platforms, and any program whose users already hold USDC or USDT and want to spend it without an off-ramp.
Conclusion
The Marqeta–BVNK partnership is best read as a distribution deal with a network strategy behind it. Marqeta gets a regulated stablecoin layer it can offer to its entire customer base without building one.
BVNK gets a major issuer-processor plugged into its infrastructure. Mastercard, which owns BVNK, gets both of them aligned around its rails and its Open USD standard within a month of closing the acquisition.
For fintechs, the near-term product is straightforward: a stablecoin balance with a card attached, spendable anywhere Mastercard is accepted, with no blockchain build required. The longer-term question is how much of the promised "additional Mastercard capabilities" materializes, and what it costs programs in network flexibility to get there.
Stablecoin Insider will track the first live programs on this integration and any further detail on Open USD as it's published.
