Stablecoin Market 'Winner Takes All': Network Effects Build a Moat
On June 30, Open Standard, a stablecoin project backed by 140 globally renowned enterprises, officially announced plans to launch a new US dollar stablecoin called Open USD (OUSD) later this year, directly challenging Circle's USDC. Following the announcement, Circle (NYSE: CRCL) shares plunged more than 17% at one point, alarming investors. Circle founder and CEO Jeremy Allaire swiftly published a detailed rebuttal, arguing that the stablecoin market follows a "winner takes all" structure. He emphasized that USDC's decade-long investments in application integrations, global liquidity, and regulatory compliance have created an insurmountable moat. The response helped Circle shares rebound 4% on July 1, though they ultimately closed down 1.09%.
Allaire explained that stablecoin networks are platform-based businesses with strong network effects, similar to other internet public utilities. Network strength is determined by the number and breadth of applications and services integrated into the network. Each new developer or service provider integration generates additional network effects, attracting more developers, increasing utility, and driving demand for the digital currency itself, which in turn strengthens liquidity network effects. Today, USDC has thousands of service integrations, with protocols like CCTP and Gateway enhancing interoperability, security, and liquidity globally — an ecosystem built over nearly a decade.
Liquidity Network Effects: A Decade-Long Deep Barrier
Allaire stressed that liquidity is a fundamental barrier. For a stablecoin to achieve scale and utility, it must possess deep liquidity — both on the primary market (e.g., direct banking liquidity through major global financial centers) and the secondary market (accessible and tradeable liquidity across regions connected to various fiat instruments). USDC has spent nearly a decade building its liquidity network, now deeply embedded in exchanges, DeFi platforms, payment service providers (PSPs), regional exchanges, and many other institutions. According to data from Artemis, a third-party analytics firm, USDC processed nearly $30 trillion in on-chain transaction volume in Q1 2026, accounting for 80% of all USD stablecoin transactions on blockchains. USDT handled the remaining 20%, while all other USD stablecoins combined comprised less than 0.5%. Allaire argued that while some stablecoins may have some circulating supply, primarily driven by promotional and incentive activities, their actual usage is extremely limited — precisely because of inadequate liquidity and network utility.
Regulatory Compliance: Global Licensing and Trust Advantage
The third layer of moat comes from deep integration with policy and regulatory environments. Circle has obtained licenses in multiple jurisdictions — USDC is currently the only major global stablecoin that can be used across Europe and Japan in its entirety. Allaire highlighted that Circle has taken a leading role in securing official recognition, registration, licensing, and acceptance for USDC in the world's most important markets. Behind this lies a global banking, reserve management, treasury, and liquidity management system capable of operating nearly around the clock across global markets and banking systems. This level of globalization and the resulting trust are difficult for later entrants to replicate in the short term.
OUSD Model Controversy: Free Minting and Alliance Model Face Reality
Allaire delivered sharp criticism of OUSD's proposed features, including "free minting and redemption" and an "everyone has a voice" alliance governance model. He noted that while free redemptions sound appealing, market reality shows that stablecoins offering good redemption facilities, ample liquidity, and zero fees often become the exit channel for competitors' stablecoins. Circle addresses this through contractual mechanisms rather than blanket fee waivers. Regarding the alliance model, Allaire stated bluntly that its track record is "absolutely disappointing." Large enterprise groups suffer from poor coordination and misaligned incentives, leading to slow progress and rarely creating spaces for lasting innovation and competitiveness. Circle experimented with a similar approach in the early days of USDC, and even with few participants, encountered numerous challenges and complexities. Allaire expressed a preference for smaller, tighter strategic collaborations led by independent product and platform builders.
Circle's Future Strategy: Expanding Product Stack and Open Collaboration
Finally, Allaire reaffirmed Circle's strong partnership with Coinbase and outlined the company's diversification of its product and platform stack, including Arc, CCTP, CPN, StableFX, Agent Stack, and more. He also noted that Circle is actively expanding collaborations with dozens of other stablecoin issuers, helping them issue via Arc, leverage interoperability infrastructure, gain support in Circle wallets, and become settlement and FX options on CPN and StableFX. He stated, "We are firmly bullish on the growth of the stablecoin ecosystem and welcome OUSD as a new member of the community." This signals that while Circle defends its competitive advantages, it remains open to cooperation and competition in the expanding digital dollar market.
