Arbitrum's ARB Token Jumps 19 Percent as Robinhood Chain Revenue Sharing Kicks In

Arbitrum's ARB token surged 19 percent over 24 hours on Thursday, July 9, 2026 (18 Tir 1405), becoming the top-performing asset among the top 100 cryptocurrencies, after the launch of a revenue-sharing model tied to Robinhood Chain. According to CoinDesk, Robinhood Chain, built on Arbitrum's technology stack, logged $568 million in trading volume in a single active day. Under the arrangement, 10 percent of the chain's net protocol revenue flows back to the Arbitrum ecosystem, split between 8 percent to the Arbitrum DAO treasury and 2 percent for development funding. Brendan Ma, head of investment strategies at the Arbitrum Foundation, said the day's activity put Robinhood Chain on an annualized revenue run rate above $12.5 million.
