The Robinhood Effect
On June 29, Robinhood Crypto teased its “biggest crypto announcements of the year” with a fireside chat at Cannes featuring Ethereum’s Vitalik Buterin, Robinhood Crypto’s Johann Kerbrat, and A.J. Warner from Offchain Labs.

This immediately triggered rumors that Robinhood might integrate Arbitrum into its upcoming blockchain infrastructure for European stock trading.
Adding to the hype, former Ethereum core dev Eric Connor suggested that “Robinhood chose Arbitrum,” igniting hopes of a long-term strategic partnership. The result was a parabolic rally in ARB.

Such large-scale movement typically signals an intent to sell, and the price action confirms it: with a 10% drop. The timing indicates classic “buy the rumor, sell the news” behavior.
Technical Analysis: Warning Signs and Possible Scenarios
On the daily chart, the BoP indicator is deeply negative at -0.86, reflecting dominant seller control in the market. Meanwhile, the RSI on the daily chart has dropped to 48.88, with the moving average at 43.27.
These momentum indicators reveal that the ARB rally has lost momentum and is vulnerable to deeper corrections unless fresh bullish catalysts emerge soon.

For ARB, the immediate support lies at the 0.236 Fib level of $0.2937. If broken, price could test the recent local bottom at $0.2526. On the other hand, bulls face resistance at $0.38 (0.618 Fib) and $0.4267 (swing high).
A break above $0.4267 could open the gates to higher targets at $0.5343 (1.618 Fib), $0.7085 (2.618 Fib), and even $0.99 (4.236 Fib), though such upside would require sustained bullish momentum.
