TLDR
- ARB rose over 30% in 24 hours, breaking out of the 7–10 cent range it had held since June
- Robinhood Chain generated $1.92 million in 24-hour revenue, the most of any blockchain
- Arbitrum’s DAO received $175,612 in the past 24 hours under the Arbitrum Expansion Program revenue-share model
- Arbitrum retained $1.6 billion in bridge asset netflow, leading all chains including Ethereum
- Total value locked on Arbitrum rose $170 million over 13 days to reach $1.412 billion
Arbitrum’s ARB token climbed more than 30% in 24 hours, rising to around 11 cents and breaking out of the 7–10 cent range it had held since June 2026.
The move was tied directly to surging activity on Robinhood Chain, an Ethereum layer-2 network launched by Robinhood on July 1. The chain is built on Arbitrum’s technology stack.
Robinhood Chain generated $1.92 million in revenue over a 24-hour period, according to DeFiLlama. That made it the top-earning blockchain in that window, ahead of Canton at $1.76 million, Tron at $974,039, Base at $98,416, and Ethereum at $75,004.
Under the Arbitrum Expansion Program, chains using the Arbitrum stack pay 10% of chain profit back to the ecosystem. The Arbitrum DAO received $175,612 in the past 24 hours, $363,153 over seven days, and $531,641 over 30 days.
ARK Invest analyst Lorenzo Valente highlighted the structure in a post on X, writing: “Ethereum’s cut is a fixed-ish L1 data-posting cost, not a revenue share. Arbitrum’s cut is a true percentage-of-revenue license. So on a spike day, Arbitrum scales up with REV but Ethereum barely moves in dollar terms.” Valente’s point underlines why traders focused on ARB as Robinhood Chain revenue spiked.
Bridge Flows and On-Chain Activity
Arbitrum led all chains in bridge asset netflow over the past day, retaining $1.6 billion in value. Ethereum and Robinhood Chain followed behind. Positive netflow means more capital settled on the chain than left it.
Total value locked on Arbitrum rose by $170 million over 13 days, reaching $1.412 billion. DEX volume also jumped, growing over 151% from August 29, hitting around $208.72 million.
Derivatives Market Signals Long Bias
Open interest in ARB rose 65%, reaching $169 million. The funding rate stood at 0.0055%, with the majority of positions leaning long. Short liquidations also contributed to the price move upward.
Trading volume in ARB hit $618 million in 24 hours, an eightfold increase from the prior day. ARB bottomed near 7.3 cents on August 18 before the current rally began.
Ryan Myher, COO at Genius, noted that capital tends to rotate to correlated assets once the primary trade has moved. “ARB is the obvious downstream exposure given the relationship between the two,” he said, referring to Robinhood Chain.
The largest revenue sources on Robinhood Chain over 24 hours were trading bot GMGN at $1.23 million and launchpad Pons at $948,044, both ahead of Uniswap at $445,379.
ARB carries a market cap of around $746 million. A token unlock of approximately 139 million ARB is scheduled for September 23, 2026, representing roughly 1.4% of total supply.
