Over $550M a Year Gets Pulled From Ethereum — Just by Reordering Transactions

In 2026, more than $550 million a year gets extracted from Ethereum alone through MEV (Maximal Extractable Value) — with comparable sums pulled on BNB Chain, Solana, and Arbitrum, CalmOps notes.

What MEV actually is: extra profit earned by reordering, inserting, or excluding transactions within a block, on top of the normal block reward and gas fees. For example, someone can slot their own trade right before a large user trade if they can see in advance that it will move the asset's price, ethereum.org explains.

The market is highly concentrated: just 5 block-building companies control 96.7% of all MEV blocks, and more than 95% of Ethereum validators use the MEV-Boost tool because it boosts their staking rewards by 20-50%.

What this means in practice: MEV isn't a hack or anything illegal — it's a built-in feature of how blockchains with an open mempool work. But for an ordinary user, it means a large trade can execute at a slightly worse price than expected, simply because someone saw it before it landed in a block.
