Key Takeaways:
- ARB is up 40% in a week, driven by a Robinhood teaser and growing speculation around a potential partnership.
- On-chain activity is rising, with new wallet addresses surging ahead of a scheduled token unlock.
- Technical indicators show a breakout, but the rally’s sustainability depends on whether hype turns into hard news.
After weeks of price stagnation, Arbitrum (ARB) is making waves again, posting a massive 20% gain in the last 24 hours and nearly 40% over the past week. The Ethereum Layer-2 scaling solution has reclaimed a spot in the spotlight, now trading around $0.3690 with its market cap topping $1.83 billion.
ARB also leads CoinMarketCap’s daily gainers, while daily trading volume has surged 528% to over $702 million—a sign of revived investor interest.
Robinhood Teaser Sparks Speculation
The rally appears to have been ignited by a teaser from Robinhood’s official X (Twitter) account, promoting an upcoming panel in Cannes. The event features Robinhood Crypto GM Johann Kerbrat, Offchain Labs’ A.J. Warner, and Ethereum co-founder Vitalik Buterin.
Vitalik’s in town.
— Robinhood (@RobinhoodApp) June 29, 2025
Join us in Cannes for a fireside chat with our crypto GM, @JohannKerbrat, the founder of Ethereum, @VitalikButerin, and the CSO of @offchainlabs, @ajwarner90.
Tune in tomorrow at 7:45pm CEST on Robinhood X and YouTube.
The teaser instantly sparked rumors of a potential Robinhood–Arbitrum collaboration, possibly tied to Robinhood’s expanding crypto presence in Europe. Although no partnership has been confirmed, market sentiment turned bullish almost immediately, pushing ARB out of its long-standing downtrend.
On-Chain Metrics Point to Renewed Interest
The rally isn’t just driven by hype. On-chain data shows a 40% rise in new and active Arbitrum wallet addresses over the past week, indicating real usage and adoption. This uptick is especially timely as a major ARB token unlock looms, an event that many feared would increase sell pressure.

Meanwhile, large on-chain transactions suggest that $ARB's chips may have changed.

However, with demand spiking and momentum building, the unlock may now be less of a threat. Instead, it could be absorbed by the surge in buying activity.

Technical Breakout Signals Bullish Momentum
Technically speaking, ARB has broken out of a months-long downtrend, flipping previous resistance into support around the $0.36 level. If bulls maintain control, the next key resistance zones lie at $0.42 and $0.48. A confirmed Robinhood partnership or continued on-chain strength could even drive prices toward $0.50 and beyond.
That said, the rally still hinges heavily on speculation. If no formal announcement follows, profit-taking could quickly reverse gains, leaving ARB vulnerable to a pullback.
