Robinhood Chain Trading Frenzy Sends Arbitrum Up 19%

U.S. online brokerage Robinhood is expanding aggressively into crypto with a new blockchain built on Arbitrum, an Ethereum Layer 2 scaling solution. The chain could generate substantial trading revenue for Robinhood while returning 10% of net protocol revenue to the Arbitrum ecosystem, underscoring the deepening integration of traditional brokerages and decentralized finance technology.

According to a Bernstein report published in July 2026, daily trading volume on Robinhood Chain has surged to $568 million, quickly placing it among the five largest decentralized exchanges by volume. The onchain trading frenzy directly drove a 19% one-day surge in Arbitrum’s native ARB token on July 15, marking a notable recent influx of capital and market gain.
