Arbitrum (ARB)

bitcoinethereumnews.com reports that Arbitrum (ARB) has rallied over 120% in September, rising from approximately $0.08 in late August to nearly $0.20. This surge is primarily attributed to Robinhood Chain, a specialized Arbitrum chain that recently surpassed $2 million in daily transaction revenue. Ten percent of this net protocol revenue is returned to the Arbitrum ecosystem, potentially annualizing to $73 million if current rates hold.
Gross revenue for Robinhood Chain jumped from roughly $54,700 on August 22 to over $1.08 million by August 30, with Arbitrum’s matching stake rising to $108,000. The Arbitrum Foundation noted that the network handled 478 million transactions in the first half of 2025, with monthly stablecoin transfer volume exceeding $70 billion. During this period, ArbitrumDAO earned $6.19 million, while Robinhood Chain’s license fees comprised 35% of DAO revenue in July.
Futures open interest increased by approximately 30% since August 31 as traders opened new long positions, adding leverage to the expanding spot market. Despite this fundamental support, the rally appears technically stretched with an RSI of 85. The price recently touched $0.206 before settling near $0.195, well above the 200-day average of $0.119. Holding the $0.17–$0.18 zone is critical to maintaining the breakout structure after such a rapid increase.
How the market reacted
Whalio's own Binance spot order flow for ARB, measured when this story was written up on 6 September 2026. Not the outlet's figures.
ARB is currently trading at $0.1772, with a 24-hour buy ratio of 50.3% indicating a near-even split between buyers and sellers. The 1-hour buy ratio stands at 51.8%, suggesting a slight short-term preference for buying, while the 4-hour ratio is lower at 49.4%, hinting at fading momentum over a slightly longer timeframe. The 24-hour volume delta is positive at +$423,929, meaning more money flowed into buys than sells over the day. This net buying pressure is further confirmed by a Cumulative Volume Delta (CVD) of +$3,200,544, showing sustained aggressive buying. However, the 4-hour volume delta is negative at -$166,214, indicating that recent hourly intervals have seen more selling pressure than buying. Net buying occurred for 16 of the last 24 hours, with spot volume reaching $50,594,720 across 337,612 trades.
The latest daily buy ratio of 46.4% sits at the 8th percentile of the last 324 days, against a median of 49.6% - among the weakest buying days it has had.
Was that an ordinary day?
The same Binance spot measurements for ARB, averaged over the days leading up to the story.
Over the preceding week, the average buy ratio was 49.9%, making the current 24-hour ratio of 50.3% a marginal increase of 0.4 percentage points. Trading volume has been 1.69 times the weekly average, signaling significantly higher activity than usual. While the price rose 102.1% over eight days, the total volume delta for that period was -$246,563, showing that despite the price surge, net selling pressure outweighed buying over the longer term. Net buying was recorded on only 3 of the past 7 days, contrasting with the 16 days of net buying in the last 24 hours. This suggests that while today is an unusually active day with net inflows, the broader weekly trend has been mixed with periods of net outflow.
