Arbitrum (ARB)

Cryptotimes.io reports that Arbitrum’s ARB token climbed 26% in 24 hours, outperforming Bitcoin and Ether as it traded at $0.1085. The rally coincided with record activity on Robinhood Chain, which generated $2.13 million in fees and $1.92 million in revenue. Decentralized exchange trading on the network reached $1.462 billion, surpassing the $16,000 collected by Arbitrum One.
This activity benefits the ecosystem because Robinhood Chain uses Arbitrum Orbit technology, sending 8% of net revenue to the ArbitrumDAO treasury and 2% to a developer guild. Derivatives activity also spiked, with futures volume surging 1143.15% to $1.37 billion and open interest rising 80.91% to $164.68 million. Technical analysis shows ARB broke out of a six-week range between $0.075 and $0.100 and moved above a descending trendline.
The price approached resistance near $0.1193, the 0.618 Fibonacci retracement level, before pulling back toward $0.1100. The Relative Strength Index reached 69.38, nearing overbought territory. A break above resistance could target $0.14 or $0.15, while a failure might see a drop to $0.08705 support. The rally faces a token unlock of 92.6 million ARB on September 16.
How the market reacted
Whalio's own Binance spot order flow for ARB, measured when this story was written up on 1 September 2026. Not the outlet's figures.
Whalio data shows ARB trading at $0.1094 with a 24-hour buy ratio of 51.1%, indicating a slight majority of buyers over the full day. However, short-term pressure has shifted, with the 1-hour and 4-hour buy ratios dropping to 48.2% and 48.6% respectively. This divergence suggests that while buying pressure existed over the longer timeframe, it is fading in the immediate term. The 24-hour Volume Delta is positive at +$421,827, showing net buying over the day, but the 1-hour Delta is -$32,985, indicating recent selling pressure. Volume Delta measures the net value of market orders, so a negative reading means sellers are currently more aggressive than buyers in that window. The 24-hour CVD closed at +$102,584, confirming that cumulative buying has outweighed selling over the full period.
The latest daily buy ratio of 46.5% sits at the 8th percentile of the last 281 days, against a median of 49.6% - among the weakest buying days it has had.
Twenty-four hours later
What ARB did over the 22 hours after the story broke. The market moves for its own reasons; this is what happened, not what the story caused.
Was that an ordinary day?
The same Binance spot measurements for ARB, averaged over the days leading up to the story.
Compared to the preceding week, today’s buy ratio is 2.1 points higher than the 7-day average of 49.0%. Spot volume is 4.55 times the weekly average, marking an unusually active trading day. Despite this volume spike, only 2 of the last 7 days saw net buying, and the 8-day Volume Delta remains negative at -$194,176. This indicates that while today is an outlier in terms of activity, the broader weekly trend still favors sellers. The price has risen 12.8% over the past 8 days, but the negative cumulative delta suggests much of this move may have been driven by short-term speculation rather than sustained accumulation.
