Stablecoins Are the Internet's Dollar, and Nobody Noticed

There are two loud stories about stablecoins and both are wrong. The crypto maximalist tells you they are the on-ramp to a decentralized financial revolution that ends the dollar. The skeptic tells you they are a lawsuit waiting to happen, a Tether-shaped hole in the financial system. I have listened to both for years, and while they argued, the boring, actually important thing happened underneath them.

Stablecoins became the dollar's settlement layer for the internet. Not the speculative dollar, not the meme-coin casino chip. The plumbing. In the year to September 2025 they moved about $9 trillion in bot-adjusted transaction volume, up 87%, which is more than half of what Visa processes and over five times PayPal.^[1] That is not a revolution and it is not a scam. It is infrastructure, and infrastructure is where the money is.

The law that made them boring, and that was the point

On July 18, 2025, President Trump signed the GENIUS Act into law, the first US federal regulatory framework for payment stablecoins.^[2] Read the actual requirements and you will notice they are not written for revolutionaries. Issuers must hold 100% reserves in liquid assets like dollars and short-term Treasuries, publish monthly reserve disclosures, comply with the Bank Secrecy Act, and retain the technical ability to freeze, seize, or burn tokens on a lawful order.^[3]

Freeze, seize, and burn. That is the line that tells you everything. The whole ideological pitch of crypto was censorship resistance, money the state cannot touch. The law that unlocked stablecoins for mainstream finance does the exact opposite. It mandates a kill switch. And that is precisely why banks, payment processors, and Fortune 500 treasurers can now touch this stuff without their compliance department having a heart attack.

Here is the part that should reframe how you think about it. Stablecoin issuers now collectively hold more than $150 billion in US Treasury securities, which makes the sector the #17 holder of US government debt.^[1]More than 1% of all US dollars now exist as tokenized stablecoins. The thing crypto skeptics said would undermine the dollar has instead become one of the dollar's biggest new buyers. Every USDC in circulation is a bid for Treasuries. The US government did not fight this. It legalized it. Of course it did.

The product is not speculation. It is settlement.

If you want to understand why serious money is pouring into this, stop looking at retail and look at cross-border B2B. This is the use case that matters, and it is the one both loud camps ignore because it is unsexy.

Monthly B2B stablecoin payments grew from under $100 million in early 2023 to more than $6 billion by mid-2025.^[1] Surveys cited in industry reporting show about 77% of corporates naming cross-border settlement as their top reason to adopt stablecoins.^[9] Not yield farming. Not trading. Paying a supplier in Vietnam without eating three days and a fat FX spread through the correspondent banking system.

Think about what a cross-border wire actually is today. Your bank talks to an intermediary bank, which talks to a correspondent bank, which talks to the recipient's bank, each taking a cut and a day, each closed on weekends, all coordinated over messaging rails from the 1970s. A stablecoin transfer is a single settlement on a blockchain that clears in seconds, at any hour, for cents. If you run a business that pays or gets paid across borders, that is not a philosophical debate about the future of money. That is a line item you can cut this quarter.

Follow the builders, not the tokens

The clearest signal that this is real is who is building the rails. Not crypto degens. Stripe. The most respected private company in payments spent $1.1 billion to acquire stablecoin infrastructure startup Bridge, closing February 4, 2025, the largest stablecoin-infrastructure acquisition on record.^[5] Bridge is not a token. It is a single API to receive, convert, and settle payments across chains and stablecoins. It is a shovel.

Then Stripe went further. In September 2025 it teamed with Paradigm to incubate Tempo, a payments-focused Layer-1 blockchain, which raised a $500 million Series A in October 2025 at a $5 billion valuation.^[6] Look at the list of firms that gave design input: Visa, Deutsche Bank, Shopify, Nubank, Revolut, and OpenAI. That is not a crypto cap table. That is the establishment quietly agreeing on a new settlement network. When Stripe and Visa are helping design the same chain, the argument about whether this is a fad is over.

Visa itself is not sitting this out. As of December 2025 it was settling roughly $3.5 billion on an annualized basis in stablecoins, expanded to four stablecoins (USDC, PYUSD, USDG, EURC) across four chains (Solana, Ethereum, Stellar, Avalanche).^[10] The company whose entire moat is settlement is voluntarily routing settlement over public blockchains. Incumbents do not do that unless the alternative is getting disintermediated.

Circle is the pure-play, and the market noticed

If you want the cleanest read on how the market values this, look at Circle. It went public on the NYSE under ticker CRCL on June 5, 2025, priced its IPO at $31, and closed up 168% at $83.23 on day one, raising over $1.1 billion at a valuation above $16 billion.^[7] That is not a sleepy debut. That is the public market repricing what a stablecoin issuer is worth once it is legal and audited.

The business underneath is almost comically simple. Circle reported $658 million in Q2 2025 revenue and reserve income, up 53% year over year, with USDC circulation of $61.3 billion.^[4]By Q4 2025, USDC circulation had grown 72% year over year to $75.3 billion, and reserve income was up 69% to $733 million. How does it make that money? It holds your dollars in Treasuries and keeps the yield. You get a dollar that moves at internet speed. Circle gets the float. In a world where the risk-free rate is real again, holding tens of billions of other people's dollars is a spectacular business.

Circle also launched its Circle Payments Network in May 2025 with four active corridors and a pipeline of more than 100 financial institutions, with partners including Binance, Corpay, FIS, Fiserv, and OKX.^[4] FIS and Fiserv are the deeply unglamorous core-banking processors that run the back offices of thousands of actual banks. When they show up as partners, you are not looking at a crypto experiment anymore. You are looking at a payments network being wired into the existing financial system.

The concentration problem nobody wants to talk about

Now the part the bulls skip. This market is a duopoly, and one half of it is the half everyone spent a decade worrying about. In mid-July 2026 the total stablecoin market cap was about $303 billion, with Tether's USDT at roughly $184 billion and Circle's USDC at roughly $73 billion.^[8]That is about 88.5% of the entire market in two tokens. For scale, PayPal's PYUSD, a token from a company with hundreds of millions of users, had a supply of about $3.95 billion, ranking around #7.^[8]

USDT being the biggest is the tension at the center of this whole story. Tether is the token skeptics have questioned for years over the quality and transparency of its reserves, and it is the largest dollar stablecoin on earth by a wide margin. The GENIUS Act is, in part, an attempt to force that entire category into 100% reserves and monthly disclosure. Whether the biggest incumbent fully lives inside that US framework or routes around it offshore is the single most important open question in the sector. If you are underwriting this trend, that is the risk you are actually taking.

How I actually think about it

Strip away both loud narratives and here is what is left. Stablecoins are not going to replace the dollar. They are the dollar, in a new wrapper, moving over new rails, and the US government figured out it would rather own that transition than fight it. The GENIUS Act is not crypto winning. It is the dollar absorbing crypto's best idea and keeping the kill switch.

For anyone trying to position around this, the lesson is the same one that has held in every technology shift I have watched. The interesting money is rarely in the thing everyone is arguing about. It is in the layer underneath. Not the token, the network. Not the speculation, the settlement. Stripe understood that when it paid $1.1 billion for an API. Visa understood it when it started settling on Solana. Circle's public-market investors understood it when they bid the stock up 168% in a day.

The maximalists wanted a revolution and got regulated. The skeptics wanted a collapse and got Treasuries. What actually shipped was the least dramatic and most useful thing possible: a dollar that finally moves as fast as the internet it lives on. That is the whole story, and almost nobody noticed while they were busy arguing about the wrong thing.
