In 2025, dollar stablecoins settled $33 trillion of raw on-chain volume [VERIFY: Artemis/Allium raw volume data], more than the $25.5 trillion Visa and Mastercard processed combined across their fiscal years [VERIFY: Visa and Mastercard annual reports]. That sentence describes a payments network at global-incumbent scale, and it describes a network no legislature designed, no central bank operates, and no user ever voted on. The dollars are minted by private companies, the largest of them headquartered in El Salvador [VERIFY: Tether relocation announcement, January 2025], the ledger is public infrastructure nobody owns, and the settlement is final in minutes, around the clock, while the card networks still batch to next business day [VERIFY: network settlement documentation]. The honest version of the story requires deflating the raw number, naming who actually issues the dollars, and separating trading churn from the payments volume that is quietly becoming the point.
Card-network scale, measured honestly
Start with the caveat, because the caveat is where the credibility lives. Raw on-chain volume counts every transfer: exchange deposits, market-maker rebalancing, bot loops that move the same dollar fifty times a day. Chainalysis strips the identifiable bot churn and still arrives at $28 trillion for 2025 [VERIFY: Chainalysis adjusted-volume methodology], and the stricter adjusted-volume metrics published by Artemis and Allium filter further, putting the organic-payments slice far below the raw total [VERIFY: Artemis/Allium adjusted dashboards]. This article inherits its headline framing from a prior Ezana Echo piece, The Cow Is the Collateral, which used the same pair of numbers with the same caveat: raw $33 trillion, bot-adjusted $28 trillion, either way a rail carrying card-network scale [VERIFY: Ezana Echo, tokenization-collateral-2026]. The deflated number is the one worth arguing from, and the deflated number still clears the card networks.
The cadence of the volume matters as much as the total. Monthly raw settlement climbed from roughly $2.1 trillion in January 2025 to roughly $3.4 trillion in December [VERIFY: Artemis/Allium monthly data], while monthly transaction counts rose from about 950 million to about 1.5 billion, roughly 14.7 billion transfers on the year [VERIFY: Artemis/Allium transaction counts]. Volume growing 60% while counts grow at a similar clip means average ticket size held while the mix shifted: the payments share of activity grew all year, pulling average transaction size down within the organic slice even as institutional settlement blocks got larger [VERIFY: Artemis/Allium adjusted volume data]. A network whose transaction count compounds alongside its dollar volume is behaving like payments infrastructure, not like a casino chip.

No committee planned this. Tether launched in October 2014 under the name Realcoin [VERIFY: company history], a convenience token for exchanges that could not get bank accounts. USDC followed in 2018 as a Circle and Coinbase joint venture built to be the audited alternative [VERIFY: 2018 announcements]. The category then survived, in sequence, the failures that were supposed to end it: TerraUSD, an algorithmic design with no full reserve, collapsed in May 2022 and erased roughly $40 billion [VERIFY: May 2022 coverage]; USDC itself broke to roughly $0.87 in March 2023 when Circle disclosed $3.3 billion stranded at Silicon Valley Bank [VERIFY: Circle disclosures], and repegged within days when the deposits were guaranteed. Each failure culled a design, not the category, and the survivors absorbed the volume. By August 2023 PayPal was issuing its own token [VERIFY: PayPal announcement], by June 2025 Circle was a NYSE-listed company [VERIFY: NYSE listing data], and in July 2025 the GENIUS Act gave the category its first US federal framework [VERIFY: Public Law record, July 2025].

The supply side is a duopoly with a long tail. Of roughly $280 billion in stablecoins outstanding as of mid-2026 [VERIFY: DeFiLlama/Artemis supply data], Tether’s USDT accounts for about $155 billion and Circle’s USDC about $60 billion [VERIFY: issuer attestations], leaving every other issuer to split the remainder. That is of a kind no card network exhibits: Visa and Mastercard route payments but do not issue the money moving over them, while Tether both operates nothing and issues everything, collecting the float. The float is the business. Tether reported roughly $13 billion in profit for 2024 [VERIFY: Tether attestations], and CEO Paolo Ardoino has put its direct and indirect US Treasury exposure above $120 billion [VERIFY: Tether attestations; TIC data], a book that would rank among the top-20 holders of US government debt, sovereign nations included.
Share of supply and share of settlement are different leaderboards, and the difference is velocity. USDT turned over roughly 140 times its average supply in 2025; USDC, with a third of Tether’s float, spun at roughly 210 times, reflecting its role as the settlement asset of regulated venues and DeFi [VERIFY: Artemis/Allium volume data]. The extremes tell the sharpest stories: First Digital’s FDUSD turned over roughly 480 times its small base, a velocity inflated by zero-fee exchange trading promotions rather than organic payments [VERIFY: exchange fee-promotion coverage], while the long tail of yield-bearing designs barely moves at all, parked at a velocity near 25 because holders treat the token as a deposit, not a payment instrument [VERIFY: Artemis/Allium data]. A dollar of supply is not a dollar of settlement; the pie below sizes issuers by the volume they actually carry.

Decompose the flow and the network looks like three networks stacked. The large majority of raw volume is professional plumbing: exchange settlement, market-maker rebalancing, and DeFi flows where stablecoins serve as the leg of lending and derivatives positions [VERIFY: Artemis/Allium flow-classification data]. The organic-payments slice is the smallest, and it is the one growing fastest, because the price gap it attacks is enormous: the global average cost of sending a $200 remittance through conventional channels is roughly 6.4%, versus under 1% on stablecoin rails [VERIFY: World Bank Remittance Prices Worldwide]. In Lagos and Buenos Aires the use case is blunter than remittances: dollar stablecoins trade at persistent premiums to official exchange rates and function as household dollarization, a savings account denominated in someone else’s currency that no local bank can freeze into a devaluation [VERIFY: P2P pricing data; Chainalysis geography reports].
That corridor economics is why the ticker list for this story extends past crypto. Western Union’s core consumer money-transfer business is concentrated in exactly the high-fee corridors stablecoin rails price against [VERIFY: Western Union segment disclosures], which makes WU the clearest structural short-side exposure to the payments slice compounding. On the other side, Stripe now runs stablecoin payouts as a product line on rails it paid $1.1 billion to own [VERIFY: Stripe/Bridge deal terms], and PayPal’s PYUSD, still small at roughly $300 billion of 2025 volume, exists so that the distribution giant is holding its own token when the corridor flips [VERIFY: PayPal disclosures].
The incumbents pay to stand on the rails
The named threat is behaving like an acquirer, not a victim. Mastercard’s agreement to buy London-based BVNK for up to $1.8 billion ($1.5 billion fixed plus $300 million contingent, signed March 2026) is the largest acquisition in stablecoin history [VERIFY: Mastercard announcement]. Visa has settled card obligations in USDC with selected partners since pilots beginning in 2021 [VERIFY: Visa announcements] and now operates an anchor validator on Tempo, the Stripe-backed chain that debuted in early 2026 [VERIFY: Visa/Tempo announcements]. Crypto M&A overall ran about $37 billion in 2025, up more than sevenfold in a year [VERIFY: deal-tracking data]. Coinbase, meanwhile, collects roughly half the reserve income on USDC under its agreement with Circle [VERIFY: Circle filings], making COIN a stablecoin-float stock wearing an exchange’s clothes. The pattern is pursued from the outside in: the card networks are buying seats on a settlement layer they did not build, precisely the dynamic the Ezana Echo tokenization piece, The Cow Is the Collateral, documented from the asset side when it traced migrating onto the same rails [VERIFY: Ezana Echo, tokenization-collateral-2026].
The Treasury bid and the policy loop
Washington did eventually vote on something: the GENIUS Act, signed July 2025, requires issuers to hold 1:1 reserves in cash and short-dated Treasuries with monthly disclosure [VERIFY: statutory text]. Read cynically, the law conscripts the settlement layer into the Treasury market. Combined issuer holdings of US government debt already sit near $180 billion [VERIFY: aggregated attestations], and Treasury Secretary Scott Bessent has projected stablecoin-driven demand for Treasuries exceeding $2 trillion by 2028 [VERIFY: Bessent remarks, 2025]. Every offshore household that dollarizes through USDT extends one wallet at a time, at zero cost to the US government and considerable profit to a company in El Salvador. The friction runs the other way in Europe: MiCA’s caps on large-stablecoin activity have kept USDT delisted from EU-regulated venues [VERIFY: MiCA text; delisting notices], the first sustained attempt by a major bloc to vote against the settlement layer after the fact.
We are going to keep the US the dominant reserve currency in the world, and we are going to use stablecoins to do that.
— Scott Bessent, US Treasury Secretary, 2025 [VERIFY: confirm exact wording and venue]
How to position
The equity map is short and legible. Circle (CRCL) is the pure play and a rate trade in disguise: most of its revenue is yield on short-dated Treasuries, so Fed cuts compress the model regardless of volume growth [VERIFY: Circle filings]. Coinbase (COIN) carries the same float economics through its USDC revenue share with more diversified volume exposure. Visa (V) and Mastercard (MA) are paying billions to convert an existential threat into an acquired capability, which is what the BVNK and Tempo moves are; the position is a hedge purchased with shareholder money, and it is rational. PayPal (PYPL) owns distribution and a small token waiting on the corridor flip, and Western Union (WU) is the structural short-side read on the payments slice. Jeremy Allaire’s Circle and Ardoino’s Tether split the issuance duopoly between a filer and an attestation publisher, and that disclosure gap is itself a position: the regulated issuer trades at a multiple, the offshore one keeps the margin.
The base case: adjusted volume keeps compounding, the payments slice grows into the churn, and the settlement layer gets formalized by acquisition and statute until the distinction between card rails and stablecoin rails stops mattering to the end user. The bear case is a run: a reserve failure or a frozen banking partner at a major issuer, a depeg that does not repeg, and the $180 billion Treasury bid unwinding into a risk-off market. The history in FIG. 2 cuts both ways, evidence the category survives failures and evidence the failures keep coming. Investors can track the formalization in the disclosures themselves: Ezana’s SEC filings and lobbying datasets show the card networks and issuers spending on exactly the policy loop this article describes. Nobody voted on the settlement layer. The vote happening now is whether it gets absorbed or replaced, and the incumbents have already cast theirs in cash.
