Ethereum has captured the largest share of a recent surge in the euro-denominated stablecoin market, adding $32 million in market capitalization over the past 30 days. This significant contribution accounts for the bulk of a $39.9 million overall increase across three networks, with Arc and Base securing the remaining growth.
While $32 million may seem modest compared to the colossal dollar-denominated stablecoin market, where Tether alone boasts over $100 billion, it signifies substantial progress for euro stablecoins. This sector, which was virtually nonexistent just two years ago, has experienced remarkable expansion, growing from approximately €50 million in early 2024 to an estimated $835 million by mid-August 2026.
Ethereum currently dominates the euro stablecoin landscape, holding an impressive 69.5% of the total market share. Its current supply ranges between $579 million and $589 million. Since January 2026, Ethereum has facilitated the injection of roughly $125 million in additional euro stablecoin supply.
Dominant Players and Regulatory Framework
Two primary stablecoins, Circle’s EURC and SG-Forge’s EURCV, are the leading forces in this market, collectively representing over 80% of the total euro stablecoin supply. Both are designed to comply with the European Union’s Markets in Crypto-Assets (MiCA) framework, which has become the de facto standard for legitimate euro stablecoin issuance. By mid-2026, an estimated €674 million of the euro stablecoin supply had achieved MiCA compliance.
Arc and Base’s Contributions
Arc launched its public mainnet on September 16, 2026, with a specific focus on stablecoin-native payments and foreign exchange. The network has so far deployed approximately $7 million in EURC. Base contributes a smaller but notable share, accounting for around 6-7% of the overall euro stablecoin market.
The Impact of MiCA
The MiCA regulation has provided stablecoin issuers with a clear and defined set of rules. Compliance with MiCA allows issuers to operate across all 27 EU member states with a single license. This regulatory passport is a significant advantage for companies like Circle and SG-Forge, a subsidiary of the major French bank Société Générale, as they target enterprise and institutional clients.
The substantial growth of the euro stablecoin market, from €50 million to over $800 million, has been largely driven by institutional adoption. This expansion has been catalyzed by MiCA’s regulatory infrastructure, rather than by retail speculation.
Market Concentration and Potential Risks
Ethereum’s commanding 69.5% market share positions it as the clear leader. However, Arc’s strategic placement presents a potential conflict of interest, as Circle serves as both the issuer of EURC and the operator of Arc. With two stablecoins controlling over 80% of the supply and one network holding nearly 70% of the market capitalization, any significant disruption affecting these key entities could have widespread repercussions throughout the entire sector.
