Ethereum's Maximal Extractable Value (MEV) ecosystem experienced a significant decline in profitability in 2025, with average net profits per sandwich attack dropping to just $3. Despite decentralized exchange trading volumes reaching $100 billion monthly, total losses from these attacks amounted to $40 million for the year. Monthly MEV profits decreased from $10 million in late 2024 to $2.5 million by October 2025. Stablecoin pools and algorithmic dominance became key areas of focus, with 38% of attacks targeting stablecoins. A single entity, 'Jaredfromsubway.eth,' controlled approximately 70% of these attacks, underscoring the increasing centralization within the MEV landscape.
