ARB jumped 26% to about $0.1101 as Robinhood Chain — built on Arbitrum Orbit — logged $2.13 million in 24‑hour fees and $1.462 billion in DEX volume, routing 8% of net revenue to ArbitrumDAO and 2% to a developer guild, boosting crypto adoption and DeFi fee accrual for ARB holders. The rally stalled at the 0.618 Fibonacci near $0.1193 with RSI near 70, open interest up 62% and funding flipped positive; downside risks include Robinhood’s gas subsidy expiring end‑September and ~92.6 million ARB token unlocks on Sept 16, putting support at $0.1100 with lower targets at $0.1045 and $0.0891.

Arbitrum price gained 26% over 24 hours, trading near $0.1101 on Tuesday. Bitcoin (BTC) and ether slipped over the same stretch, leaving the layer 2 token to rally against a falling market.

The move followed record activity on Robinhood Chain, a network built with Arbitrum Orbit technology that sends part of its revenue back to the Arbitrum ecosystem.

Robinhood Chain Revenue Explains the Arbitrum Price Move

Robinhood Chain booked $2.13 million in chain fees over 24 hours, according to DefiLlama. Chain revenue reached $1.92 million, while decentralized exchange (DEX) volume hit $1.462 billion.

Arbitrum One collected roughly $16,000 in chain fees over the same window. The Robinhood network now out-earns the chain it forked from.

Under the Arbitrum Expansion Program, Orbit chains route 8% of net revenue to the ArbitrumDAO treasury and 2% to a developer guild. Therefore, ARB holders hold a claim on fees earned outside Arbitrum One.

Arbitrum Price Analysis Shows Resistance at $0.1193

ARB broke out of a six-week range between $0.075 and $0.100 on the daily chart. However, the rally stalled at the 0.618 Fibonacci retracement near $0.1193.

Price wicked to $0.1202 before sellers stepped in. ARB now sits at the 0.5 Fibonacci level near $0.1100, which capped the token twice earlier this year.

The Relative Strength Index (RSI) reads near 70 and is trending higher. That level also marks where momentum in most altcoins tends to cool.

Analyst MasterCryptoHq reads the same structure as a symmetrical triangle nearing resolution.

ARB Price Prediction Hinges on a September Deadline

The four-hour chart places ARB inside an ascending channel. Its midline sits near $0.1007, matching the 0.382 Fibonacci support.

A close below $0.1045 would weaken the breakout. Beneath that, $0.0891 marks the next demand zone.

Meanwhile, two dates complicate the bull case. Robinhood’s 90-day gas subsidy expires near the end of September, and roughly 92.6 million ARB unlock on September 16.

Derivatives positioning has also turned crowded. Open interest climbed 62%, and funding flipped positive, which leaves late longs exposed if $0.1100 gives way.

ARB needs $0.1100 to hold as support. Beyond that, the rally needs Robinhood Chain volume to survive without a subsidy paying for it.
