ArbitrumDAO generated $6.19 million in revenue in the first half of 2026, while the Arbitrum Foundation recorded $27.7 million in USD costs plus 4.6 million ARB in additional expenses, according to the foundation’s latest report. Revenue came from Arbitrum One transaction fees, Timeboost, AEP licensing fees and treasury returns, with gross margins above 97%. The foundation’s biggest costs were technical infrastructure at $8.55 million, general and administrative expenses at $6.62 million, and R&D at $6.59 million. Ecosystem growth projects added $3.1 million in costs plus 4.6 million ARB, with 43.2% of funding directed to DeFi and fintech and 29.9% to enterprise initiatives. As of June 30, the foundation held $86.88 million in liquid and usable assets. The report also highlighted AEP licensing fees as an emerging revenue stream, with Robinhood Chain’s post-period growth indicating the model could become a more meaningful contributor to ArbitrumDAO revenue if activity remains sustained.
