The Great Stablecoin Fragmentation: New Entrants Chip Away at the USDT/USDC Duopoly | Bitcoin Index

For years, stablecoins meant two things: Tether’s USDT and Circle’s USDC. Together, they controlled roughly 90% of the $200 billion market. That duopoly is cracking.

By February 2026, their combined market share has dropped to 85%. That’s five percentage points captured by new entrants in just one year. PYUSD (PayPal), RLUSD (Ripple), USD1 (World Liberty Financial), and a wave of traditional finance players are taking those five points. They’re just getting started.

This is the first real competition the stablecoin market has seen. And it’s being driven by two forces: regulatory clarity that lets compliant players enter confidently, and distribution advantages that crypto-native startups could never match.

The numbers tell the story

As of February 21, 2026, the top eight stablecoins by market cap break down like this:

Rank	Stablecoin	Market Cap	Share	Issuer
1	USDT	$183.7B	60.6%	Tether
2	USDC	$74.5B	24.6%	Circle
3	USDS	$9.9B	3.3%	Sky (formerly MakerDAO)
4	USDe	$6.2B	2.1%	Ethena Labs
5	USD1	$5.0B	1.7%	World Liberty Financial
6	DAI	$4.2B	1.4%	MakerDAO (legacy)
7	PYUSD	$4.0B	1.3%	PayPal/Paxos
8	RLUSD	$1.6B	0.5%	Ripple

Total market: $302.9 billion

The top two still control 85.2%. But a year ago, that number was closer to 90%. The next six stablecoins collectively hold 10.3% of the market, a chunk that barely existed 12 months ago.

Both USDT and USDC grew in absolute terms. USDT went from $142.1B to $183.7B (+30%). USDC went from $57.2B to $74.5B (+30%). But the overall stablecoin market grew 31%, faster than either could capture. New entrants got the incremental growth.

Meet the new players

PayPal USD (PYUSD): The distribution play

PYUSD went from $0.76 billion in February 2025 to $4.04 billion in February 2026. That’s 434% growth. It now holds 1.5% of the stablecoin market.

The reason is simple: PayPal has 430 million consumer accounts (PayPal + Venmo) and a 36 million merchant network. When you already own the pipes, integrating a stablecoin into existing payment flows isn’t hard.

PayPal announced in June 2025 that PYUSD would expand to the Stellar blockchain, targeting cross-border payments in 170+ countries. May Zabaneh, VP of PayPal’s Blockchain Group, said:

“For years, stablecoins have been deemed crypto’s ‘killer app’ by combining the power of the blockchain with the stability of fiat currency. As we see cross border payments being a key area where digital currencies can provide real world value, working with Stellar will help advance the use of this technology and provide benefits for all users.”

In January 2026, PayPal partnered with Fiserv, a financial technology giant that serves thousands of banks. The partnership creates interoperability between PYUSD and Fiserv’s FIUSD stablecoin, opening access to financial institutions that would never touch crypto directly.

Most PYUSD adoption is likely happening inside PayPal’s ecosystem. But the Fiserv partnership and merchant acceptance layer create external utility. That’s different from earlier crypto-native stablecoins that relied on DeFi protocols for distribution.

Ripple USD (RLUSD): The regulatory first-mover

RLUSD launched in December 2024. By February 2026, it reached $1.6 billion in market cap (0.5% share). That’s fast for a brand-new stablecoin.

What makes RLUSD different? Dual regulatory approval. It has a New York Department of Financial Services (NYDFS) trust charter and conditional federal OCC approval. It’s the first stablecoin with both state and federal oversight.

Ripple expanded RLUSD in December 2025 to Ethereum Layer 2 networks (Optimism, Base, Ink, Unichain) via Wormhole’s Native Token Transfers. It also launched on the XRP Ledger, giving it access to Ripple’s existing enterprise relationships in cross-border payments.

The geographic strategy is deliberate. Ripple is targeting remittance corridors in Africa and the Middle East, where dollar-pegged stablecoins are in demand and banking infrastructure is weak.

World Liberty Financial USD1: The political play

USD1 went from zero to $5 billion in 11 months. That’s the fastest growth of any new stablecoin in this cycle.

USD1 is associated with World Liberty Financial, a crypto venture tied to the Trump family. It launched in March 2025, right as U.S. crypto regulation shifted toward a more permissive stance. By December 2025, it crossed $3.3 billion in circulation.

In December, World Liberty announced deployment on the Canton Network, a privacy-enabled blockchain for regulated financial markets. It’s backed by U.S. Treasuries, dollars, and cash equivalents. World Liberty Trust Company (WLTC) is pursuing a purpose-built stablecoin trust bank charter.

The political branding and institutional focus helped USD1 scale faster than crypto-native competitors. Whether that momentum holds depends on regulatory durability and whether institutions actually adopt it for settlement.

Sky USDS: The DeFi evolution

USDS is the upgraded version of DAI, launched in September 2024 when MakerDAO rebranded to Sky. It’s now the third-largest stablecoin at $9.9 billion.

This isn’t really a “new entrant.” DAI still exists at $4.2 billion, and users can upgrade DAI to USDS 1:1. Combined, they hold $14.1 billion, roughly where DAI stood before the rebrand.

But USDS represents further fragmentation. It inherits MakerDAO’s deep DeFi liquidity and collateral infrastructure. It also offers sUSDS, a yield-bearing version that earns interest from protocol revenue. For DeFi users, USDS is a more attractive alternative to plain USDC.

Ethena USDe: The synthetic dollar

USDe is different. It’s not backed by fiat in a bank account. It’s a synthetic dollar created using delta-neutral derivatives strategies (long ETH collateral + short ETH perpetual futures).

USDe peaked at around $15 billion in mid-2025, then experienced a deleveraging event in October 2025. It’s now at $6.2 billion (2.1% market share). It’s been integrated as collateral on major centralized exchanges like Binance and Bybit.

The risk profile is different from fiat-backed stablecoins. USDe depends on derivatives market liquidity and funding rates. But it’s proven there’s demand for yield-bearing synthetic dollars that don’t rely on traditional banking infrastructure.

Traditional finance joins the party

The bigger story isn’t just crypto companies launching stablecoins. It’s that traditional finance is entering aggressively.

Fiserv (FIUSD)

Fiserv serves thousands of banks with core banking technology. In January 2026, it announced FIUSD and partnered with PayPal for PYUSD/FIUSD interoperability. That gives banks a path to stablecoin settlement without touching crypto directly.

Stripe (Bridge / USDH)

Stripe acquired Bridge, a stablecoin infrastructure company. In September 2025, Stripe won the bid to issue USDH on Hyperliquid, a DeFi platform, beating out Paxos, Abora, and Ethena. Stripe’s small business payment network creates a merchant adoption path that crypto startups can’t match.

Visa stablecoin settlement

Visa reported a $3.5 billion annual run rate for stablecoin-based settlement by late 2025. It supports 130+ stablecoin-linked card programs across 40+ countries. Visa isn’t issuing its own stablecoin, but it’s building the rails for others to plug into.

Bank-backed stablecoins

Societe Generale, Vantage Bank, and consortiums of large banks are exploring stablecoin issuance. Major retailers (Amazon, Walmart) are reportedly considering it. The GENIUS Act, which took effect in July 2025, created a federal framework for stablecoin regulation in the U.S., making it easier for banks to enter.

This is the shift that matters. For years, stablecoins were a crypto thing. Now they’re a payments thing. And payments is where traditional finance has distribution, compliance infrastructure, and customer trust.

What this means for USDC

Circle is not failing. USDC grew from $57.2 billion to $74.5 billion in one year. That’s 30% growth.

But USDC lost market share for the first time in years. It went from 28.6% to 28.4% (a small decline, but directionally significant). And the competitive pressure is coming from multiple angles:

DeFi alternatives: USDS and USDe offer yield, making them more attractive for liquidity providers and traders.
Payment-focused stablecoins: PYUSD leverages PayPal’s merchant network. RLUSD targets remittances.
Traditional finance: Bank-backed stablecoins will have regulatory trust that crypto-native issuers struggle to build.

Circle’s revenue model also faces pressure. USDC earns yield from reserves invested in U.S. Treasuries. Analysts at Mizuho warned in Q3 2025 that declining interest rates would pressure Circle’s revenue, and emerging competition from PayPal and Ripple could eat into market share.

Circle is responding. It launched the Circle Payments Network in 2025, connecting 100+ financial institutions for instant cross-currency settlement. It built Arc Blockchain, an enterprise-grade blockchain for stablecoin payments, FX, and capital markets. It went public on the NYSE in June 2025 to raise capital for expansion. And it expanded its BlackRock partnership, using USDC to settle tokenized portfolios and private funds.

But distribution is the game now, and Circle is competing with companies that already have 430 million users (PayPal), thousands of bank relationships (Fiserv), or federal regulatory approval (Ripple).

Payments are (finally) coming

Stablecoins are still primarily used for trading and investment, not payments. PayPal CEO Alex Chriss said in December 2025:

“We’re seeing more people hold crypto than using it to make payments. That will take time to ramp up. We’re making headway particularly in geographies that have inflationary pressures. Stablecoins pegged to U.S. dollars are valuable there.”

But payment use cases are emerging:

Cross-border B2B payments

Chris Jones, Managing Director at PSE Consulting, told American Banker:

“Cross-border payments have been slow and expensive, taking several days and costing up to 10 times more than domestic payments. This is particularly problematic for companies making a large number of cross-border transactions. Stablecoins can make these payments instant, and the technology is in place.”

Enterprises are using stablecoins for treasury optimization, FX hedging, and supplier payments. This is happening quietly, outside of consumer-facing apps.

Merchant payouts

E-commerce platforms (Amazon, Etsy, eBay, Shopify) have slow, expensive payout processes. Stablecoins enable instant settlement. Chris McGee, Global Head of Financial Services Consulting at AArete, said:

“The first wave of stablecoin innovation and scaling will really happen in 2026. The largest focus next year will center around emerging use cases for payment and fiat-backed stablecoins as well as more investment opportunities in this space.”

Remittances

Stellar’s integration with PYUSD targets 170+ countries. RLUSD focuses on Africa and the Middle East. High-inflation economies (Argentina, Turkey, Nigeria) prefer dollar-pegged stablecoins over local currencies.

Settlement infrastructure shift

Monica Eaton, CEO of Chargebacks911, told American Banker:

“Stablecoins will play a greater role in settlement in the next year. It will be the way stablecoins quietly replace legacy clearing infrastructure.”

That’s the real shift. Not flashy consumer apps. Not DeFi yield farming. Boring, invisible settlement infrastructure: the kind that moves trillions of dollars and takes three days to clear. Stablecoins can do that in seconds.

The duopoly will remain, but the days of 90%+ are over

USDT and USDC will stay dominant. USDT has the deepest liquidity on every major exchange and dominates in Asia, Latin America, and offshore markets. USDC has regulatory compliance, DeFi integration, and institutional trust.

But the combined 90% market share is gone. New entrants have proven they can capture incremental growth. And the next wave (bank-backed stablecoins, merchant-issued stablecoins, enterprise treasury stablecoins) will fragment the market further.

The difference between 2026 and 2023 is regulatory clarity. The GENIUS Act in the U.S. and MiCA in the EU created frameworks that let compliant, well-capitalized players enter confidently. PayPal, Ripple, Fiserv, and Stripe don’t need to rely on offshore banking or regulatory arbitrage. They can build in the open with federal approval.

Market share is no longer sticky. Distribution, compliance, and utility matter more than first-mover advantage. And the companies with the best distribution (PayPal, Stripe, Visa) aren’t crypto companies. They’re payments companies that added crypto rails.

The next 12 months will show whether this fragmentation accelerates or stabilizes. Watch for bank-backed stablecoins, payment adoption metrics, and whether USDC can hold 25% share. The stablecoin wars are just getting started.
