Arbitrum jumps 26% as Robinhood Chain fees top $1M daily

Robinhood Chain's revenue-sharing model is reshaping the ARB token narrative, but the September 23 unlock looms.

ARB rose 26 percent to $0.1101 in 24 hours as of 09:44 UTC Tuesday, rallying as Bitcoin and ether fell on Robinhood Chain fee growth.

Robinhood Chain, an Ethereum Layer 2 built on Arbitrum Orbit technology, generated more than $1 million in fees over the past 24 hours, according to on-chain data. The chain operates under Arbitrum's revenue-sharing model, sending 10 percent of net protocol revenue to the Arbitrum ecosystem — 8 percent to the ArbitrumDAO treasury and 2 percent to development.

Trading volume for ARB jumped 586 percent during the rally, with open interest climbing to roughly $88.1 million, Coinglass data shows. The funding rate turned more positive, indicating growing long bias, while larger short liquidations suggest the upswing was partly fueled by closing bearish positions.

The rally comes as Arbitrum activated the ArbOS Elara upgrade, introducing protocol-level compliance filtering and customizable priority fees for dedicated chains. The upgrade also increased Stylus smart-contract capacity from 24KB to 96KB, allowing developers to deploy larger applications without splitting code across contracts.

Robinhood Chain's Revenue Model Reshapes ARB's Value Proposition

Robinhood Chain has surpassed $1 billion in total value locked since launching, with multi-billion-dollar daily DEX turnover in recent days. The chain uses ETH for gas rather than ARB, meaning increased activity does not directly create token demand. However, the revenue-sharing agreement provides a new financial pipeline to the Arbitrum ecosystem that did not exist before.

ARB has historically functioned primarily as a governance token without direct yield from network activity. The revenue model changes that narrative by giving the ecosystem a growing treasury that could fund development, incentives, or future governance-approved distributions.

$0.12 Resistance and the September Unlock

ARB rebounded from the $0.07 to $0.075 support zone and broke above its rising trendline, approaching the first major resistance at $0.12. A decisive daily close above that level could expose $0.14 to $0.15, with the $0.19 to $0.23 region as the next major target.

The primary near-term risk is the token unlock scheduled for September 23, 2026, which will release approximately 139 million ARB — roughly 1.4 percent of total supply — into circulation. Combined with elevated open interest and positive funding rates, the unlock could trigger selling pressure if the breakout fails to hold.

ARB remains far below its all-time high, and a single-day rally does not reverse a multi-month downtrend. Sustained follow-through buying above $0.12 on the weekly timeframe, supported by continued Robinhood Chain revenue growth, would be needed to confirm a larger reversal.
