Four income lines with a gross profit margin of 97%
The Arbitrum Foundation released a semi-annual progress report on September 2, covering the six months ended June 30, 2026. During the six months, Arbitrum DAO received a cumulative amount of US$6.19 million from four revenue lines, including: Arbitrum One transaction fees, Timeboost, Arbitrum Extension Program (AEP) license fees, and treasury revenue. The gross profit margin on agreed revenue exceeds 97%, compared with more than 90% for the full year of 2025.
The network processed 478 million transactions during this period, accounting for approximately 18% of its cumulative total of 2.7 billion transactions. The average monthly stablecoin transfers exceeded US$70 billion, and the number of stablecoin holders increased by 40% to 10.5 million. Arbitrum ranks first in the number of tokenized real-world asset deployments, with more than 2000 assets deployed.
As of June 30, 2026, the DAO held US$125 million in non-native treasury assets (excluding ARB tokens), which provides it with capital flexibility to seize opportunities to drive growth in the Arbitrum ecosystem and DAO revenue.
Robinhood Chain opens up new sources of income
The report also highlighted a development that just exceeded the reporting period. Robinhood Chain will be launched on the public main network on July 1, 2026. This is a dedicated chain based on Arbitrum that will ultimately settle to Ethereum. Previously, its testnet had processed more than 200 million transactions. The chain is operated by Robinhood Crypto and is built based on the Arbitrum Extension Program, which allocates 10% of the fees charged by Robinhood Chain to the Arbitrum ecosystem: 8% of this goes into a treasury controlled by token holders, and 2% goes to fund development.
Robinhood Chain launched its main network on July 1, and the expansion plan license fee contributed US$360,000 that month, accounting for 35% of Arbitrum DAO's revenue. This chain has begun to reshape the structure of the DAO's revenue sources-external licensors are now important revenue contributors, along with Arbitrum One's own transaction fees.
As of August 17, 2026, approximately 9.23 billion ARBs (92.3% of total supply) have been unlocked or held by the Arbitrum DAO treasury. The remaining 770 million ARBs belong to the balance of the original ownership plan, and the last batch will be unlocked in March 2027.
