Arbitrum DAO generated approximately $6.19 million in revenue in the first half of 2026, with sources including Arbitrum One transaction fees, Timeboost auction rights, Expansion Program licensing fees, and treasury management income. The protocol's gross profit margin exceeded 97%. As of the end of June, the DAO held around $125 million in non-ARB treasury assets. After Robinhood Chain launched its mainnet on July 1, the Expansion Program brought in about $360,000 in licensing fees that month, accounting for 35% of Arbitrum DAO's July revenue. This program requires chains that settle outside of Arbitrum One and Nova but use the Arbitrum tech stack to return 10% of net protocol revenue to the Arbitrum ecosystem.
