What happened
Cathie Wood, chief executive of ARK Invest, said Wall Street analysts who cover Visa and Mastercard are underestimating the disruption Circle is bringing to card-network economics, according to a CryptoBriefing report published Saturday evening. Wood's argument, per the report, is that Circle's USDC is not simply another dollar-backed token competing with Tether. It is a payment rail that settles instantly, clears at a fraction of interchange, and plugs directly into merchant processors that already sit downstream of Visa and Mastercard.
That framing puts Circle in the same conversation as the networks themselves rather than as a crypto-native curiosity. Wood is not neutral here. ARK has held Circle exposure since the company's public debut and has repeatedly modelled stablecoin adoption as a structural drag on card-network take rates.
What is new is the directness of the accusation against sell-side analysts, who have largely kept Visa and Mastercard estimates intact despite the stablecoin volume ramp of the past year.
Why it matters
Visa and Mastercard together clear roughly $20 trillion in annual payment volume and earn a fee stack that has resisted every fintech challenger from PayPal to Square. The bull case on the duopoly rests on that fee stack staying intact. Wood's point is that it isn't.
Stablecoin settlement on public chains costs cents per transaction, not the 1. 5% to 3% merchants pay through the card rails. If even a slice of business-to-business flow or high-ticket consumer checkout migrates to USDC-denominated rails, the incremental margin on the marginal transaction resets lower.
