tradersunion.com reports that Arbitrum (ARB) advanced 6.36% to trade at $0.1757 on 8 September 2026. The price sits above short- and long-term moving averages but faces medium-term resistance. A key driver is Robinhood Chain routing 10% of net protocol revenue to the Arbitrum ecosystem.
This allocation sends 8% to the ArbitrumDAO treasury and 2% to the Developer Guild. The move enhances the recurring funding base and incentivizes development. Additionally, ARB is now tradeable on Solana via the Sunrise platform.
Access is available through Jupiter and Backpack, with governance retained by native holders. This listing broadens the token's accessibility and liquidity. Technically, the H1 chart shows support at the Ichimoku Kijun level of $0.1687.
The MACD indicates strong selling momentum while the RSI stands at 49.90 with a sell bias. Analysts note that direction depends on holding critical support levels.
