Ethereum Arbitrage Surplus Favors Builders Over Fee Burning

Ethereum's arbitrage ecosystem is funneling the majority of trading surplus to block builders, with only a fraction of that value actually burned and removed from ETH's supply. According to blockchain data provider Bitquery, for every $1 in ETH destroyed by the network's fee-burning mechanism, block builders received $5.24 in receipts over a recent 30-day period. This sharp imbalance highlights how Ethereum's transaction ordering and block assembly mechanics determine who captures value-and why holding ETH is a fundamentally different bet than participating in on-chain trading or block production.

How Arbitrage Flows Through Ethereum

Arbitrage on Ethereum involves specialized software-often called searchers-scanning for price discrepancies between tokens across decentralized exchanges. When a profitable gap appears, searchers race to buy low and sell high, but competition is fierce. The real contest is not just finding the opportunity, but getting the transaction included in the right spot within a block. That's where builders come in: they assemble blocks, bundle transactions, and bid for the right to have their block proposed by a validator. The builder's address is set to receive the block's fees, but a portion is paid onward to the validator as compensation for proposing the block. The rest is retained by the builder, minus any business costs.

Bitquery's analysis, verified as of August 31, 2026, shows that 49.3% of measured arbitrage surplus went to block assembly (builders), 41.3% to trading operators (searchers), and just 9.4% was burned as network fees. The study's methodology filters for surplus no greater than the capital committed in each transaction, and does not account for onward payments from builders to validators, meaning the actual profit retained by builders may be lower. Still, the data makes clear that the largest share of arbitrage value is captured by those who control block construction, not by ETH holders or the protocol's burn mechanism.

Fee Burning Versus Block Revenue

Ethereum's EIP-1559 upgrade introduced a base fee that is destroyed with every transaction, reducing ETH's supply. But this base fee is only one part of the total payment made by users. The priority fee-an extra incentive for inclusion-goes to the block builder and, ultimately, the validator. While both fees can be present in a single transaction, only the base fee is burned. The priority fee is a direct payment to network participants, not a supply reduction. This distinction is critical: a surge in trading activity may increase total fees paid, but unless those fees are burned, they do not shrink ETH's supply. For holders, the relevant metric is the net difference between ETH created (issuance) and ETH destroyed (burn) over a given period-not the total value flowing through the network.

For context, Ethereum's supply dynamics depend on the balance between new ETH issued to validators and ETH burned via base fees. If issuance outpaces burn, supply grows; if burn exceeds issuance, supply contracts. But as Bitquery's data shows, most arbitrage-driven payments are not burned-they are captured by builders and operators. This means that high on-chain activity does not automatically translate to a deflationary ETH supply or direct value accrual for passive holders.

Winners and Losers in the Arbitrage Race

The current structure rewards those who can efficiently assemble and propose blocks, as well as trading operators who can execute arbitrage before price gaps close. Validators receive compensation for their role in proposing blocks, but their share is distinct from the builder's retained revenue. Passive ETH holders, meanwhile, benefit only if the burn rate outpaces issuance-a condition that fluctuates with network activity and fee levels. The study's allocation table covers a 30-day window without specifying exact endpoints, and a separate annual comparison includes other networks like BNB Chain, Base, Arbitrum, and Polygon, but excludes Optimism and Solana. These boundaries mean the findings are a snapshot, not a trend, and do not establish whether builder or operator profits are rising or falling over time.

For those tracking on-chain security and cross-chain movement, the mechanics of arbitrage and block assembly can also intersect with broader network risks. For example, as seen in EgonCoin's previous investigation, large-scale asset transfers and transaction ordering can have security and forensic implications that go beyond simple profit calculations.

What the Data Leaves Unanswered

Bitquery's figures do not reveal how much of the builder's receipts are ultimately paid to validators, nor do they capture all arbitrage activity across every Ethereum venue. Wallet reconciliation and incomplete venue decoding may further reduce apparent earnings. The five-to-one ratio between builder receipts and burned ETH is based on rounded shares from a specific sample, not a comprehensive accounting of all network revenue. For investors and users, this means that more transactions or higher fees do not guarantee a shrinking ETH supply or increased value for holders. Instead, the network's design channels most arbitrage surplus to those who control block assembly and transaction ordering.

During the 30-day sample ending August 29, 2026, Bitquery found that only 9.4% of arbitrage surplus was burned as ETH fees, while 49.3% went to block builders and 41.3% to trading operators. The five-to-one ratio between builder receipts and burned ETH is specific to this period and does not represent a long-term average. Ethereum's total supply and burn rate continue to fluctuate based on network activity, validator participation, and fee levels, with the protocol's issuance and destruction mechanisms determining whether supply expands or contracts in any given window.

Ethereum's fee structure and block-building incentives create a complex landscape where trading activity, block assembly, and fee burning each serve different economic interests. The protocol's design ensures that most arbitrage-driven value is captured by active participants-builders and operators-rather than by passive holders or through supply reduction. For anyone evaluating ETH as an investment, it's essential to separate the mechanics of trading profit from the realities of token supply. The evidence is clear: Ethereum's architecture rewards those who shape the flow of transactions, not those who simply hold the asset and hope for deflationary effects.

Ethereum's fee-burning mechanism, introduced with EIP-1559, was designed to align network usage with supply reduction by destroying a portion of transaction fees. But the protocol's separation of base and priority fees means that only a subset of payments actually reduce supply. The rest are distributed among builders, validators, and trading operators, reflecting the network's layered incentive structure. For users and investors, understanding these distinctions is critical to assessing who benefits from on-chain activity and how network design shapes the distribution of value.
