Arbitrum’s ARB token (CRYPTO: $ARB) jumped 19% Thursday as trading on Robinhood’s (NASDAQ: $HOOD) new blockchain pushed daily volume past $568 million and started sending revenue back into the Arbitrum ecosystem.
ARB led gains among the top 100 cryptocurrencies, while bitcoin rose about 1.5% and ether added 0.5%. The outperformance followed a fast start for Robinhood Chain, which opened to the public last week after being built on Arbitrum’s technology stack.
Robinhood Chain processed more than $568 million in trading volume on Wednesday, followed by another $350 million by Thursday. Memecoin activity accounted for much of the early rush, while stablecoin balances on the network climbed above $260 million during its first week.

Under the Arbitrum Expansion Program, chains built on its technology outside Arbitrum One contribute 10% of protocol net revenue. Robinhood Chain’s share is split between the Arbitrum DAO treasury and Developer Guild, giving the ecosystem an economic stake in the brokerage’s onchain growth.
Brendan Ma, head of investment strategies at the Arbitrum Foundation, said Wednesday’s activity put Robinhood Chain on an annualized revenue run rate above $12.5 million. He added that tokenized real-world asset activity has barely started.
Robinhood launched the chain as part of a wider crypto expansion that includes tokenized U.S. stocks for customers in more than 120 countries, DeFi-powered savings through Morpho and plans for AI-enabled trading tools. The dedicated blockchain settles to Ethereum and was designed around low-latency execution, predictable pricing and higher throughput.
FalconX previously estimated Robinhood Chain could generate about $1.1 million in transaction fees during its first six months and as much as $60 million annually by 2030.
The early trading frenzy may cool, but ARB’s rally shows the market is starting to treat Robinhood’s activity as more than a distribution win. For Arbitrum, usage on a fintech chain is now beginning to translate into revenue.
Arbitrum (CRYPTO: ARB) is currently trading at $0.0874 U.S. per digital token.
