Stablecoin Companies to Watch in 2026: Issuers and Rails

A treasury analyst at a freight forwarder in Rotterdam opens her dashboard on a Monday in October 2026 and sees three dollar balances that are not held at any bank: USDT from a supplier in Shenzhen, USDC from a client in Austin, and a small float of PYUSD that a marketplace paid out last week. Each token is a promise from a different company, held to a different standard, redeemable through a different chain of partners. Picking which stablecoin companies matter is no longer an exercise for crypto traders. It is supplier due diligence.

How we chose. We looked at companies with measurable scale as of October 2026: circulating supply for issuers, and volume, licences, funding or acquisition price for infrastructure firms. We also weighed regulatory standing and product breadth. We group companies by role rather than numbering them, and within the issuer group we order by reported supply. Every figure below is dated and linked to the source we checked.

Who are the largest stablecoin companies in 2026?

As of October 2026, the largest stablecoin company by supply is Tether, issuer of USDT at about $184 billion, followed by Circle, issuer of USDC at about $73 billion, according to DefiLlama data. Together they account for roughly 84% of a market worth about $306 billion. Behind them sits a long tail of issuers, each under $10 billion, and a fast-consolidating layer of infrastructure companies.

The concentration is the headline, but the more interesting story of 2026 is the money flowing into the plumbing. Card networks, payment processors and prime brokers have spent several billion dollars buying stablecoin infrastructure in the past twenty months, and those deals tell you where incumbents think the profits will be. For the history of how the market reached this size, see our stablecoin market report.

Which companies issue the biggest stablecoins?

In 2026 the biggest dollar stablecoins are issued by Tether, Circle, Sky, Ethena, World Liberty Financial, Paxos (including for PayPal) and Ripple. Only Tether and Circle exceed $10 billion. As of mid-October 2026 the others range from about $2 billion to $7 billion on DefiLlama, and their supply has been volatile, with some losing a third or more within months as exchange incentives changed.

Tether (USDT)

Tether is the largest issuer by a wide margin. Its first-quarter 2026 reserve report showed net profit of $1.04 billion, total assets of $191.7 billion against liabilities of $183.5 billion, and direct and indirect US Treasury exposure of $141 billion, which Crowdfund Insider reported would make it the 17th-largest holder of Treasuries in the world. Reserves also included about $20 billion of physical gold and $7 billion of bitcoin. The attestation was prepared by BDO; Tether says a full audit has begun. In January 2026 it launched USAT, a US-regulated dollar token issued through Anchorage Digital.

Circle (USDC)

Circle, now a listed company, had $73.3 billion of USDC in circulation at the end of June 2026, up 19% on a year earlier. Its second-quarter results showed $701 million of revenue and reserve income, $48 million of net income from continuing operations and $14.8 trillion of onchain USDC volume, up 151%. Its Circle Payments Network had 175 financial institutions enrolled and an annualised run rate of $14.7 billion, and its Arc blockchain was due for public mainnet on September 16, 2026.

SKSky (USDS and DAI)

Sky, the rebranded MakerDAO, runs the largest decentralised dollar. Its newer USDS token had about $6.9 billion in circulation in mid-October 2026, ahead of legacy DAI at about $4.7 billion, according to DefiLlama's stablecoin dashboard. Both are backed by onchain collateral and real-world assets rather than a single bank account, which makes Sky the main counterweight to the custodial model.

World Liberty Financial (USD1)

USD1, issued by World Liberty Financial with reserves custodied by BitGo, had about $4.15 billion in circulation in mid-October 2026, per DefiLlama, making it the sixth-largest dollar stablecoin. The project's political links draw scrutiny, and readers should note that independent reserve reporting is thinner than for the larger issuers.

ETEthena (USDe)

Ethena's USDe is a synthetic dollar backed by crypto collateral and offsetting derivatives positions rather than cash. Supply stood at about $4.8 billion in mid-October 2026, per DefiLlama, slightly ahead of DAI. Its returns come from funding rates on derivatives, which rise and fall with crypto markets. It is a yield product with market risk, not a payment token in the conventional sense.

PPPaxos and PayPal (PYUSD, USDG)

Paxos is the white-label issuer behind PayPal's PYUSD and the Global Dollar (USDG). In December 2025 it received approval to convert its New York trust charter into a federal one supervised by the OCC, as Skadden, its counsel, announced. PYUSD reached about $4.1 billion in March 2026, when PayPal expanded it from two markets to 70, COIN360 reported, then fell to about $2.9 billion by mid-October, per DefiLlama. Paxos's own USDG was slightly larger, at about $3.0 billion.

Ripple (RLUSD)

Ripple's RLUSD, issued under a New York trust charter, grew from about $130 million in mid-2025 to about $2.4 billion in mid-October 2026, per DefiLlama. Ripple uses it as a settlement asset inside its payments product, which we explain in how Ripple Payments works.

FDFirst Digital (FDUSD)

Hong Kong's First Digital shows how fragile second-tier supply can be. FDUSD was once a leading Binance trading pair, but by mid-October 2026 it was no longer among the 23 stablecoins above about $490 million on DefiLlama. In April 2025 it briefly lost its dollar peg after Tron founder Justin Sun alleged that First Digital Trust could not meet redemptions, The Defiant reported. It remains one to watch because of its base in Hong Kong, where the new stablecoin licensing regime is taking shape.

Which companies build stablecoin infrastructure?

Stablecoin infrastructure companies issue tokens for others, connect bank accounts to blockchains, hold keys and run payout networks. In 2025 and 2026 the leaders were Bridge (owned by Stripe), BVNK (being bought by Mastercard), Zerohash, Fireblocks and Anchorage Digital. Their valuations and acquisition prices now run from about $1 billion to over $4 billion.

BRBridge (Stripe)

Stripe bought Bridge for $1.1 billion in February 2025, its largest acquisition, and in February 2026 Bridge won conditional OCC approval to organise a national trust bank, according to FinTech Futures. Bridge provides APIs that let companies accept, hold and issue stablecoins, and its charter would let it hold reserves under federal supervision rather than relying on partner banks.

BVBVNK

London-founded BVNK runs stablecoin payment accounts and payouts for businesses in more than 130 countries. Mastercard agreed in March 2026 to acquire it for up to $1.8 billion, including $300 million of contingent payments, with completion expected by the end of 2026, COIN360 reported. BVNK had been valued at about $750 million in 2024, and Coinbase had earlier held talks near $2 billion.

ZEZerohash

Chicago-based Zerohash supplies crypto and stablecoin rails to brokers and fintechs including Interactive Brokers, Stripe and Shift4. It was valued at $1 billion in September 2025 after a $104 million round led by Interactive Brokers, and in May 2026 was reported to be seeking a valuation above $1.5 billion, per crypto.news, citing CoinDesk. Mastercard had considered buying it before choosing BVNK.

FIFireblocks

Fireblocks provides wallet and key-management technology to banks and exchanges. In August 2026 its Network for Payments was handling more than $100 billion a month in stablecoin transactions across more than 40 live payment providers, banks and fintechs, with over $200 billion a month across its wider platform, according to Crypto Briefing.

Anchorage Digital

Anchorage operates a federally regulated digital asset bank in the US and issues Tether's USAT. In February 2026 Tether invested $100 million at a $4.2 billion valuation, as The Block reported, alongside an employee tender at the same price. It is the clearest example of an offshore issuer buying a regulated US channel.

How do the leading stablecoin companies compare?

The table below sets out each company's base, role and latest dated metric as of October 2026. Supply figures for issuers come from DefiLlama and company results; infrastructure figures come from company results and press reports. The metrics are not directly comparable across rows, because issuers are measured by tokens outstanding and infrastructure firms by price, valuation or volume.

Tether	El Salvador	Issues USDT, USAT	~$184B USDT supply (Oct 2026)
Circle	USA	Issues USDC, EURC; runs CPN, Arc	$73.3B USDC (Jun 2026)
SKSky	Onchain protocol	Issues USDS, DAI	~$6.9B USDS (Oct 2026)
World Liberty Financial	USA	Issues USD1	~$4.15B (Oct 2026)
ETEthena	Onchain protocol	Synthetic dollar USDe	~$4.8B (Oct 2026)
PPPaxos / PayPal	USA	Issues PYUSD, USDG	~$2.9B PYUSD (Oct 2026)

Anchorage Digital	USA	Federally regulated crypto bank	$4.2B valuation (Feb 2026)

How much does each dollar of stablecoin earn? A worked example

Stablecoin issuers earn mainly from interest on reserves, so revenue per dollar outstanding is a useful yardstick. Using 2026 results, Circle earned about 3.8 cents of gross revenue per USDC dollar on an annualised basis, while Tether's annualised profit was about 2.3 cents per dollar of liabilities. The gap between gross revenue and profit is where distribution deals bite.

Here is the arithmetic, using the companies' own reported figures:

• Circle, Q2 2026. $701 million of quarterly revenue and reserve income, multiplied by four, is about $2.8 billion a year. Divided by $73.3 billion of USDC, that is roughly 3.8%. But net income from continuing operations was only $48 million in the quarter, or about 0.26% annualised. Most of the gross income is paid away to distribution partners and spent on operations.
• Tether, Q1 2026. $1.04 billion of quarterly profit, multiplied by four, is about $4.2 billion. Divided by $183.5 billion of liabilities, that is about 2.3% as profit, not revenue, and Tether's figure includes gains on gold and bitcoin as well as interest.
• Concentration. USDT at about $184 billion plus USDC at about $73 billion is $257 billion, or 84% of the $306 billion market. The next six tokens in this article (USDS, DAI, USDe, USD1, PYUSD and RLUSD) add up to roughly $26 billion, about 8%, on mid-October DefiLlama data.

The lesson is that size alone does not decide profitability. Circle's business model rewards the exchanges and wallets that hold USDC, while Tether keeps most of its spread. Every smaller issuer faces the same choice: pay heavily for distribution, as PYUSD and FDUSD did through incentives, or stay small. Our explainer on how stablecoin issuers make money goes deeper.

The stablecoin market has two giants and a crowd of companies renting their way to relevance.

Why are incumbents buying stablecoin companies?

Between February 2025 and March 2026, Stripe, Mastercard, Ripple and others agreed deals worth more than $5 billion for stablecoin infrastructure. The buyers want licences, banking relationships and engineering teams that would take years to build, and they want them before US rules under the GENIUS Act fully take effect.

The pattern is consistent. Stripe paid $1.1 billion for Bridge's issuance and orchestration stack. Mastercard agreed up to $1.8 billion for BVNK's payout network. Ripple paid $1.25 billion for prime broker Hidden Road, $200 million for Rail and $1 billion for treasury software firm GTreasury. Tether bought into Anchorage at $4.2 billion. Each deal joins a company with distribution (merchants, cardholders, institutions) to a company with stablecoin rails.

For businesses choosing providers, consolidation cuts both ways. A Mastercard-owned BVNK or Stripe-owned Bridge brings a balance sheet and compliance resources a start-up cannot match. It also brings product roadmaps set by a parent whose interests may not align with a small corridor. Our pieces on stablecoin payments for business and stablecoin start-up funding track the trade-offs.

What should you watch next?

Over the next six months, the events most likely to reshape this list are the closing of Mastercard's BVNK deal, US federal trust charters moving from conditional to final, Tether's first full audit, and the implementation of GENIUS Act rules for issuers. Each could shift market share or open new distribution.

• BVNK closing, by end of 2026. Mastercard expects completion by year end, subject to regulatory approvals. Watch whether BVNK's corridors are folded into Mastercard's cross-border products.
• Federal trust charters. Paxos, Bridge and Ripple all hold OCC approvals of varying finality. Final charters would let them hold reserves under one federal supervisor.
• Tether's audit. Tether says an audit has begun. A full audit from a major firm would remove the largest standing objection to USDT among US institutions.
• GENIUS Act implementation. Rules from US regulators will determine how offshore issuers such as Tether can serve American users, and why USAT exists. Our GENIUS Act tracker follows each rulemaking.
• Zerohash's raise. A round above $1.5 billion would confirm that independent infrastructure can still command premium valuations after the card networks' buying spree.
