Mastercard Spent $1.8 Billion on Stablecoin Insurance

Written by: Ada, Deep Tide TechFlow

Mastercard Chief Product Officer Jorn Lambert once said in an interview: “Card business doesn’t really have any problems that need solving.”

Then he led a $1.8 billion acquisition of BVNK.

On March 17, Mastercard announced it would acquire London-based stablecoin infrastructure company BVNK for up to $1.8 billion, with $1.5 billion fixed and $300 million performance-based. This is the largest acquisition in the stablecoin space ever, surpassing Stripe’s $1.1 billion purchase of Bridge in 2024.

When someone says “there are no problems” while dropping $1.8 billion, it only means one thing: problems are already here, too big to ignore.

A Knife at the Heart of Card Networks

To understand this deal, first understand Mastercard’s revenue structure.

According to Raymond James analyst John Davis, about 37% of Mastercard’s revenue comes from cross-border transactions and international e-commerce. Visa’s share is similar, at 36%. Morningstar analyst Brett Horn directly states: “Cross-border payments are just a small part of the entire payments world, but they are a major part of card network revenue.” Mastercard’s adjusted operating profit margin for 2025 is close to 60%, with cross-border business being the main profit contributor.

Stablecoins are now targeting this lucrative segment.

Traditional cross-border payments use SWIFT via correspondent banks, taking 3 to 5 days to settle, with fees of 3% to 6%. Stablecoin payments settle on-chain within minutes, with fees below 1%, and operate 24/7. McKinsey data shows that by 2025, stablecoin card issuance will reach $4.5 billion, a 673% increase. These cards allow users to spend stablecoins directly at any merchant accepting Visa or Mastercard, without converting to fiat first. Stablecoins are leveraging card networks’ acceptance infrastructure to bypass traditional settlement routes.

What truly worries card networks isn’t today’s volume, but the trend. U.S. Treasury Secretary Scott Bessent predicts stablecoin supply will reach $3 trillion by 2030, with Citi’s bullish forecast at $4 trillion. Today’s volume is negligible, but in cross-border and merchant settlement scenarios, the fees collected by card networks and the costs of stablecoins differ by an order of magnitude. Once major platforms start accepting stablecoins for direct settlement, the fee model of card networks will be challenged.

Industry experts from Third Bridge point to a deeper threat: the biggest risk comes from merchant adoption. Amazon, Walmart, Shopify—all have strong incentives to replace card payments with low-cost stablecoin channels, redefining checkout economics.

Harvey Li, founder of Tokenization Insight, says: “The card network is the most vulnerable payment track to disruption by stablecoins.”

Front-end cards, back-end blockchain

BVNK’s business is straightforward: bridging fiat and on-chain stablecoins for enterprises, covering cross-border transfers, B2B settlements, remittances. Clients include Worldpay, Deel, Flywire, operating in 130 countries, with an annual transaction volume of $30 billion and annual revenue of $40 million, but not yet profitable.

Mastercard’s annual net profit is about $15 billion, with a profit margin of 45%. $1.8 billion is only 0.4% of its market value—barely pocket change. It’s not about the $40 million annual revenue, $30 billion transaction volume, or even BVNK’s technology.

On the day stablecoins become the main settlement layer, Mastercard won’t be on the sidelines.

Mastercard’s vision is clear: embed BVNK into its network to enable 24-hour stablecoin settlement, stablecoin checkout within payment gateways, and seamless conversion between fiat and digital assets. According to American Banker, after the acquisition, BVNK will be integrated into Mastercard’s network at three levels: providing stablecoin settlement for merchants and acquirers, adding stablecoin checkout in Mastercard’s payment gateway, and creating cross-card, account, and wallet fiat conversion channels.

Raj Dhamodharan, Mastercard’s EVP of Blockchain and Digital Assets, explains: “We see stablecoins as a rail system. Each stablecoin can be viewed as a global ACH, with consumers unaware of the complexity.” Karen Webster, editor of PYMNTS, sums it up more directly: “Mastercard isn’t fighting stablecoins; it’s integrating them.”

Integration is key. Front-end remains a card, but the back-end shifts to blockchain. Users won’t notice the change, but the underlying settlement infrastructure has been replaced.

However, the $1.8 billion is an entry ticket, not a finished product.

One of BVNK’s selling points is chain-agnosticism, capable of operating on Ethereum, Solana, Tron, and other chains. But each chain’s confirmation times, gas fee structures, and security models differ. Harmonizing these differences to Mastercard’s required consistency level is a significant engineering challenge. BVNK operates in 130 countries, each with different stablecoin regulations. The GENIUS Act governs the U.S., Europe has MiCA, and Asian countries each have their own rules—compliance costs will be a continuous black hole. Harmse, BVNK’s co-founder, told CNBC that the company is growing fastest in the U.S., which hints at the core issue: the maturity of stablecoin payment infrastructure heavily depends on local regulation. Outside the U.S., conditions are far from ready.

Mastercard is acquiring a potentially powerful engine, but installing it into a 60-year-old vehicle isn’t something that can be done just by signing an agreement.

Regulatory Legitimacy: The License to Harvest the Old Order

Mastercard isn’t the only player in the race.

Stripe spent $1.1 billion to acquire Bridge; Visa partnered with Bridge to promote stablecoin cards in over 100 countries; PayPal’s PYUSD circulation exceeds $1 billion; JPMorgan launched JPMD; Citibank is considering issuing its own stablecoin. McKinsey and Artemis data project that by 2025, total stablecoin payments will reach approximately $390 billion, with 58% in B2B transactions. Cross-border vendor payments, global payroll, trade settlements—these scenarios are shifting from SWIFT to stablecoin rails.

The driving logic behind these giants’ moves is simple: rather than waiting for stablecoin companies to grow and compete, it’s better to buy them now.

BVNK’s own history illustrates this well. In December 2024, it raised a Series B at a valuation of $750 million, led by Haun Ventures, with Tiger Global and Coinbase Ventures participating. By October 2025, Coinbase entered exclusive negotiations, offering around $2 billion. A month later, Coinbase withdrew for unknown reasons. Mastercard then stepped in, acquiring BVNK for $1.5 billion fixed plus $300 million performance-based, $200 million less than Coinbase’s bid.

This structure speaks volumes. The largest crypto-native trading platform exited at the last moment, with traditional finance stepping in at a lower price. Regardless of Coinbase’s reasons for withdrawing, the result is clear: stablecoin infrastructure is ultimately absorbed by the old order, not integrated into a new one.

There’s a bigger paradox here. The crypto industry spent a decade fighting for regulatory legitimacy. The passage of the GENIUS Act and the creation of a federal framework for stablecoins are positive steps. But the biggest beneficiaries of legalization aren’t crypto-native firms—they’re Mastercard, Stripe, Visa—established players with licenses, compliance teams, and distribution networks.

Regulatory legitimacy effectively grants traditional finance a license to harvest.

Ryan Bozarth, founder of Dakota, notes that after the acquisition of Bridge and BVNK, there will be opportunities for new payment companies to emerge. He’s right. But if history is any guide, the next generation of stablecoin startups will likely face the same fate: an acquisition offer.

Electronic trading didn’t eliminate stock exchanges; the internet didn’t eliminate banks; stablecoins probably won’t eliminate card networks. But card networks will transform into something entirely different—moving from “card networks” to “multi-rail fund flow platforms.” This isn’t disruption; it’s absorption.

In the payments industry, the layer closest to users always takes the most money.

Mastercard is closest to users. The $1.8 billion it spent is just to ensure that nothing changes.
