Arbitrum DAO generated approximately $6.19M in income during H1 2026, driven by Arbitrum One transaction fees, Timeboost auctions, Expansion Program licensing fees, and treasury management.

Protocol revenue maintained gross margins above 97%, while the DAO held around $125M in non-ARB treasury assets at the end of June. Following Robinhood Chain’s mainnet launch on July 1, Expansion Program licensing fees generated roughly $360K in July, representing 35% of the DAO’s monthly income.

Under the Expansion Program, chains using Arbitrum technology while settling outside Arbitrum One and Nova return 10% of net protocol revenue to the Arbitrum ecosystem.
