Stablecoin Power Rankings 2026: Inside the $318B Market Where Tether Prints $13B Profits and Coinbase Takes Half of USDC's Revenue

Tether made $13 billion in profit last year. That's more than Goldman Sachs. And it did it with roughly 200 employees, no branches, and a product that's simply a digital dollar pegged to treasury yields.

Welcome to the stablecoin economy of 2026, where the two largest issuers control over 80% of a $318 billion market, transaction volumes have surpassed Visa and PayPal combined, and the real battle isn't about technology—it's about who captures the yield on hundreds of billions in reserves.

The Duopoly: USDT and USDC by the Numbers

The stablecoin market has exploded. Total supply jumped from $205 billion at the start of 2025 to over $318 billion in early 2026—a 55% surge in just twelve months. Transaction volumes hit $33 trillion in 2025, up 72% year-over-year.

But this growth hasn't democratized the market. If anything, it's entrenched the leaders.

Tether's Unstoppable Machine

Tether's USDT controls approximately 61% of the stablecoin market with a $187 billion market cap. Its dominance on centralized exchanges is even more pronounced—75% of all stablecoin trading volume flows through USDT.

The profit numbers are staggering:

• 2024 full-year profit: $13 billion (up from $6.2B in 2023)
• 2025 H1 profit: $5.7 billion
• 2025 Q3 YTD profit: Exceeded $10 billion
• U.S. Treasury holdings: $135 billion, making Tether one of the world's largest holders of U.S. government debt

Where does this money come from? Roughly $7 billion annually flows from Treasury and repo holdings alone. Another $5 billion came from unrealized gains on Bitcoin and gold positions. The remainder comes from other investments.

With group equity now exceeding $20 billion and a reserve buffer above $7 billion, Tether has evolved from a controversial crypto tool into a financial institution rivaling Wall Street giants.

Circle's Public Debut and the USDC Economics

Circle took a different path. In June 2025, the company went public on the NYSE at $31 per share, pricing above expectations. Shares exploded 168% on day one and have since climbed over 700% from the IPO price, giving Circle a market cap exceeding $63 billion.

USDC now holds a $78 billion market cap—about 25% of the stablecoin market. But here's what makes Circle's model fascinating: its economics are fundamentally different from Tether's.

Circle's 2025 financial trajectory:

• Q1 2025: $578.6 million revenue
• Q2 2025: $658 million revenue (+53% YoY)
• Q3 2025: $740 million revenue (+66% YoY), $214 million net income

But there's a catch that explains why Circle's profits pale compared to Tether's despite managing similar-scale reserves.

The Coinbase Connection: Where Half the USDC Revenue Goes

The stablecoin business isn't just about issuing tokens and collecting yield. It's about distribution. And Circle pays dearly for it.

Under the revenue-sharing agreement with Coinbase, the exchange receives:

• 100% of interest income from USDC held directly on Coinbase
• 50% of residual revenue from USDC held off-platform

In practice, this means Coinbase captured approximately 56% of all USDC reserve revenue in 2024. For Q1 2025 alone, Coinbase earned roughly $300 million in distribution payments from Circle.

JPMorgan's analysis breaks it down:

• On-platform: ~$13 billion USDC generates $125 million quarterly at 20-25% margins
• Off-platform: 50/50 split yields $170 million quarterly at near 100% margin

By year-end 2025, total USDC reserve income was projected to reach $2.44 billion—with $1.5 billion going to Coinbase and only $940 million to Circle.

This arrangement explains a paradox: Circle's stock trades at 37x revenue and 401x earnings because investors are betting on USDC growth, but the company that actually captures most of the economics is Coinbase. It also explains why USDC, despite being the more regulated and transparent stablecoin, generates far less profit per dollar in circulation than USDT.

The Challengers: Cracks in the Duopoly

For years, the USDT-USDC duopoly seemed unassailable. At the start of 2025, they controlled 88% of the market combined. By October, that figure had dropped to 82%.

A 6-percentage-point decline might seem modest, but it represents over $50 billion in market cap captured by alternatives. And several challengers are gaining momentum.

USD1: The Trump-Backed Wildcard

The most controversial entrant is USD1 from World Liberty Financial, a company with deep Trump family ties (60% reportedly owned by a Trump business entity).

Launched in April 2025, USD1 has grown to nearly $3.5 billion in market cap in just eight months—placing it fifth among all stablecoins, just behind PayPal's PYUSD. Its velocity metric of 39 (average times each token changed hands) indicates genuine usage, not just speculative holding.

Some analysts, like Blockstreet's Kyle Klemmer, predict USD1 could become the dominant stablecoin before Trump's term ends in 2029. Whether that's achievable or hyperbole, the growth rate is undeniable.

PayPal USD: The Fintech Play

PayPal's PYUSD started 2025 at under $500 million market cap and has climbed to over $2.5 billion—adding $1 billion in the final two weeks of 2025 alone.

The limitation is obvious: PYUSD exists primarily within PayPal's ecosystem. Third-party exchange liquidity remains thin compared to USDT or USDC. But PayPal's distribution reach—over 400 million active accounts—represents a different kind of moat.

USDS: The DeFi Native

Sky Protocol's USDS (formerly DAI) has grown from $1.27 billion to $4.35 billion in 2025—a 243% increase. Among DeFi-native users, it remains the preferred decentralized alternative.

RLUSD: Ripple's Velocity King

Ripple's RLUSD achieved the highest velocity of any major stablecoin at 71—meaning each token changed hands 71 times on average during 2025. With only $1.3 billion in market cap, it's small but intensely used within Ripple's payment rails.

The Yield War: Why Distribution Will Define Winners

Here's the uncomfortable truth about stablecoins in 2026: the underlying product is largely commoditized. Every major stablecoin offers the same core value proposition—a dollar-pegged token backed by treasuries and cash equivalents.

The differentiation happens in distribution.

As Delphi Digital noted: "If issuance becomes commoditized, distribution will become the key differentiator. Stablecoin issuers most deeply integrated into payment rails, exchange liquidity, and merchant software are likely to capture the largest share of settlement demand."

This explains why:

• Tether dominates exchanges: 75% of CEX stablecoin volume flows through USDT
• Circle pays Coinbase so heavily: Distribution costs are the price of relevance
• PayPal and Trump's USD1 matter: They bring existing user bases and political capital

The Regulatory Catalyst

The passage of the GENIUS Act in July 2025 fundamentally changed the competitive landscape. The law established the first federal regulatory framework for payment stablecoins, providing:

• Clear licensing requirements for stablecoin issuers
• Reserve and audit standards
• Consumer protection provisions

For Circle, this was validation. As the most regulated major issuer, the GENIUS Act effectively blessed its compliance-heavy model. CRCL shares surged following the bill's passage.

For Tether, the implications are more complex. Operating primarily offshore, USDT faces questions about how it will adapt to a regulated U.S. market—or whether it will continue focusing on international growth where regulatory arbitrage remains possible.

What This Means for Builders

Stablecoins have achieved something remarkable: they're the first crypto product to reach genuine mainstream utility. With $33 trillion in 2025 transaction volume and over 500 million users, they've outgrown their origins as exchange trading pairs.

For developers and builders, several implications emerge:

1. Multi-stablecoin support is table stakes: No single stablecoin will win everywhere. Applications need to support USDT for exchange liquidity, USDC for regulated markets, and emerging alternatives for specific use cases.

2. Yield economics are shifting: The Coinbase-Circle model shows that distribution partners will capture increasing share of stablecoin economics. Building native integrations early matters.

3. Regulatory clarity enables innovation: The GENIUS Act creates a predictable environment for stablecoin applications in payments, lending, and DeFi.

4. Geographic arbitrage is real: Different stablecoins dominate different regions. USDT leads in Asia and emerging markets; USDC dominates U.S. institutional use.

The $318 Billion Question

The stablecoin market will likely exceed $500 billion by 2027 if current growth rates persist. The question isn't whether stablecoins will matter—it's who will capture the value.

Tether's $13 billion profit demonstrates the pure economics of the model. Circle's $63 billion market cap shows what investors will pay for regulatory positioning and growth potential. The challengers—USD1, PYUSD, USDS—prove the market isn't as locked up as it appears.

What remains constant is the underlying dynamic: stablecoins are becoming critical infrastructure for the global financial system. And the companies that control that infrastructure—whether through sheer scale like Tether, regulatory capture like Circle, or political capital like USD1—stand to profit enormously.

The stablecoin wars aren't about technology. They're about trust, distribution, and who gets to keep the yield on hundreds of billions of dollars. In that battle, the current leaders have massive advantages. But with 18% of the market now outside the duopoly and growing, the challengers aren't going away.
