Arbitrum DAO recorded $6.19M in H1 2026 revenue from transaction fees, Timeboost, and the Arbitrum Expansion Program, with Robinhood Chain contributing over 96% of recent revenue through fee sharing. The analysis suggests Arbitrum's monetization model has expanded beyond Arbitrum One activity to include revenue from external chains built on the Arbitrum stack, though ARB token holders don't yet directly benefit from DAO cash flows.
