Stablecoins have moved from crypto plumbing to a serious payments and treasury market, and the next fight is over who gets to own the rails.
The stablecoin market is no longer just a side pocket of crypto trading. Dollar-linked tokens now sit at the center of a bigger question for fintech founders, payment companies and corporate treasurers: what happens when dollars can move like software, settle around the clock and plug directly into wallets, exchanges and business applications?
The numbers explain why the conversation has changed. Market trackers now put the broader stablecoin sector above $320 billion, roughly double where it stood two years ago, though estimates vary depending on whether synthetic dollars and newer regulated products are included. Tether remains the dominant issuer, with USDT still the liquidity standard across offshore exchanges and emerging-market crypto corridors. Circle, issuer of USDC, has become the cleaner institutional story, helped by public-market scrutiny, reserve transparency and the U.S. regulatory turn toward supervised dollar tokens.
As Reuters reported, Circle topped revenue expectations in February as USDC circulation increased and favorable U.S. rules gave the token a stronger institutional footing. Circle's latest quarterly update added to that picture, with USDC circulation reaching about $77 billion in March even as the company faced pressure from lower reserve yields. That matters because stablecoin issuers do not just process payments. They earn income from the cash and short-term Treasury assets backing their tokens, which means scale can turn into a powerful financial engine when interest rates are meaningful.
The GENIUS Act gave the U.S. market something it had lacked for years: a federal law for payment stablecoins. The law, signed in July 2025 and still moving through implementation, pushes the sector toward one-to-one backing, reserve disclosures, anti-money-laundering controls and clearer supervision for large issuers. For users, that sounds procedural. For institutions, it changes the risk calculation.
Before that framework, stablecoins were useful but awkward. A hedge fund, marketplace or global payroll company could see the advantage of instant settlement, but legal departments had to wrestle with questions about redemption rights, reserve quality, issuer failure and regulatory treatment. Clarity does not remove all of those risks, but it gives serious companies a map. That is often the difference between a pilot and a product launch.
The result is a market that is splitting into two tracks. One track is offshore liquidity, where USDT continues to dominate because it is deeply embedded in trading pairs, dollar access and crypto-native settlement. The other is regulated payments infrastructure, where USDC, PayPal USD and bank-linked products have a better chance of winning businesses that care more about compliance than exchange depth.
This is where the story becomes more interesting for startups. The obvious winners are the large issuers because they control the token, the reserves and the distribution. But the more durable opportunity may sit around them. Stablecoins need wallets, custody, compliance screening, accounting tools, tax reporting, fiat onramps, merchant settlement, fraud controls and treasury dashboards. A token can move instantly, but a company still needs software to approve it, reconcile it and explain it to auditors.
The payment use case is becoming harder to ignore
Cross-border payments are the clearest early business case. Traditional international transfers can still involve correspondent banks, prefunding, cutoff times and opaque fees. Stablecoins offer a different workflow: convert local currency into a dollar token, move it across a blockchain, then redeem or pay out on the other side. That does not magically solve compliance or local banking access, but it can remove a lot of idle capital and settlement delay.
Recent partnerships show the direction of travel. Nium has integrated Coinbase infrastructure for USDC payouts, treasury management and card programs. Wizz Financial has used BitGo infrastructure for stablecoin-powered remittance and treasury flows from the United States into global corridors. Convera and Ripple are positioning stablecoins as part of enterprise cross-border payment and treasury services. These are not fringe experiments anymore. They are infrastructure companies trying to meet customer demand before someone else owns the workflow.
Still, the market is not as clean as the enthusiasm suggests. Much of stablecoin volume remains tied to crypto trading, market making and exchange settlement. That is real usage, but it is not the same as replacing bank rails for mainstream commerce. Treasurers also have practical concerns: who holds the private keys, how redemptions work in stressed markets, which jurisdictions permit token settlement, and whether regulators will treat stablecoin activity as payments, deposits, securities activity or something else entirely.
There is also a competitive squeeze coming. If stablecoins become a mainstream financial product, banks and card networks will not sit back. Visa recently expanded its stablecoin settlement pilot to more blockchains, while JPMorgan, Coinbase, PayPal, Circle and Tether all have reasons to push deeper into the stack. Startups will need to pick their battles carefully. Building another generic wallet is a difficult proposition. Building compliance automation for stablecoin payouts into Latin America, treasury software for marketplaces, or reconciliation tools for onchain merchant settlement is much more specific and much more useful.
The next phase will be decided less by crypto ideology and more by distribution. Stablecoins are becoming reliable enough for regulated companies to consider, but still young enough that the surrounding software layer is unfinished. If the market keeps growing, the biggest prize may not be issuing the dollar token itself. It may be building the operating system that lets businesses actually use it.
