Arbitrum (ARB) surged from approximately $0.08 in late August to nearly $0.20 in September, marking one of its largest rallies in 2025. This move represents an increase of more than 120% from its recent low. The latest daily trading session alone saw an almost 10% jump in ARB price.
Robinhood Chain delivers revenue surge
Robinhood Chain, a dedicated Arbitrum-based network created by the trading platform Robinhood, appeared to drive the latest momentum. Over a 24-hour period, Robinhood Chain generated more than $2 million in transaction revenue, and 10% of its net protocol revenue is redirected to the Arbitrum ecosystem. If activity remains consistent, Arbitrum’s share could translate into an estimated annualized income of $73 million.
In late August, Robinhood Chain’s gross revenue sharply increased from about $54,700 on August 22 to more than $1.08 million by August 30. During the same period, Arbitrum’s matching stake grew from roughly $5,400 to $108,000. Key metrics across the Arbitrum ecosystem also showed notable improvement.

Market sentiment and technical outlook
Intense speculative activity has added further energy to the rally. Open interest in ARB futures contracts rose sharply during the initial breakout phase as traders increased their exposure through new long positions. Since August 31, open interest climbed by an estimated 30%, magnifying leverage in an already expanding spot market.
Currently, ARB trades near $0.195 on the daily chart after reaching an intraday peak close to $0.206. The Relative Strength Index (RSI) stands near 85, well above typical overbought thresholds. This overextension in technical indicators suggests the risk of a short-term correction despite strong fundamentals stemming from Robinhood Chain’s performance.
Presently, the rally is fundamentally supported by growth in Robinhood Chain, but the pace of ARB’s rise increases the possibility of a market correction as technical factors indicate overbought conditions.
The 200-day moving average sits near $0.119, highlighting ARB’s significant overperformance relative to its long-term trend. Maintained support at the $0.17–$0.18 range could sustain the breakout structure. However, a breakdown below this zone may trigger a deeper retracement after the notable 120% climb.
