The native token of Arbitrum (ARB) has surged over 21% in the past 24 hours, climbing from $0.30 to nearly $0.39, fueled by growing market speculation about a potential partnership with popular trading platform Robinhood. As excitement builds around this possible collaboration, increased on-chain activity and bullish technical indicators are reinforcing investor confidence in Arbitrum’s short-term price trajectory.
This rally is not occurring in isolation. The broader cryptocurrency market is experiencing renewed optimism, with Bitcoin retesting $108,000 and Ethereum breaking above $2,500. These macro-level gains have created a favorable environment for altcoins like ARB to thrive, especially those showing strong fundamentals and rising adoption.
Why Did Arbitrum’s Price Jump 21% in One Day?
According to data from blockchain analytics firm Lookonchain, the sudden surge in ARB’s value stems largely from market anticipation surrounding a potential strategic alliance between Robinhood and Arbitrum. The speculation intensified after Robinhood announced an upcoming fireside chat during the Cannes Lions Festival on June 30, 2025.
The event will feature Vitalik Buterin, co-founder of Ethereum; Johann Kerbrat, Head of Crypto at Robinhood; and a representative from Offchain Labs—the team behind Arbitrum—who will serve as Chief Strategy Officer. The discussion will be streamed live on Robinhood’s official X and YouTube channels.

While no formal announcement has been made, early reports suggest that Robinhood may be exploring the development of a blockchain-based platform powered by Arbitrum. This system could allow European investors to trade U.S. stocks seamlessly, leveraging Arbitrum’s scalable Layer 2 infrastructure for faster and cheaper transactions.
Such a move would significantly expand Arbitrum’s real-world utility, positioning it as a key player in bridging traditional finance and decentralized technologies.
Growing On-Chain Activity Signals Strong Network Health
Beyond rumors, concrete on-chain metrics support the bullish momentum behind ARB. Data from DefiLlama shows a 25% increase in daily active addresses on the Arbitrum network within the last 24 hours—jumping to over 418,400. This spike indicates heightened user engagement and growing ecosystem adoption.
Additionally, Arbitrum recorded over $300 million in decentralized exchange (DEX) trading volume in the past day alone. Its 30-day cumulative DEX volume now exceeds $17 billion, underscoring its status as one of the most active Layer 2 ecosystems.
Network revenue also rose by 20% in the same period, reaching $2.59 million—a clear sign of increasing transactional demand and improved economic activity across dApps built on Arbitrum.
Key Market Movements: Whale Activity and Exchange Flows
Large-scale investors and market makers are also making strategic moves that reflect confidence in ARB’s upward trend.
- GSR, a major market maker, deposited 9.48 million ARB tokens to Binance over the past week, likely to facilitate liquidity amid rising trading volumes.
- Wintermute, another prominent trading firm, received 50.1 million ARB from Anchorage Digital’s custodial wallet—suggesting preparation for significant trading or staking activity.
Meanwhile, open interest in ARB futures has surged by 48% to $266 million, according to Coinglass. This rise in leveraged positions indicates growing trader sentiment that ARB’s price may continue its upward momentum.
Technical Outlook: Can ARB Reach $1?
From a technical analysis perspective, ARB is showing strong signs of a potential breakout. The price recently tested resistance near $0.39—a level that could turn into support if sustained.
Analysts point to several positive indicators:
- A bullish crossover on the MACD (Moving Average Convergence Divergence)
- Increasing volume accompanying price gains
- Recovery above key moving averages (50-day and 200-day)
If bullish momentum holds, some forecasts suggest ARB could climb toward $1 in the coming weeks—a more than 150% increase from current levels.
However, downside risks remain. Traders should monitor two critical support zones:
- $0.30 – recent breakout point and psychological level
- $0.26 – long-term support where strong buying interest previously emerged
A drop below these levels could signal weakening sentiment and trigger further corrections.
