Arbitrum’s $ARB Token Surges 40% in a Week on Partnership Speculation and Whale Activity

Arbitrum’s native token, $ARB, has experienced a significant surge, climbing 40% in a week to reach $0.76. This rally is attributed to a combination of factors, including speculation around a potential partnership between Arbitrum and Robinhood, as well as substantial on-chain activity involving major market players.

The speculation surrounding a Robinhood-Arbitrum collaboration has been a key driver of the recent price increase. According to an analysis, this partnership could enable European investors to trade U.S. stocks on a blockchain-powered platform. Although the partnership has not been officially confirmed, the market has reacted swiftly, with traders pushing ARB from $0.306 to a high of $0.3867 before a brief pullback. ARB is now holding around $0.76 after jumping 18.3% in the past 24 hours. Its market cap has climbed to $1.78 billion, while the fully diluted valuation (FDV) sits near $3.6 billion.

Whale activity and custody movements have also played a significant role in the recent price surge. GSR Markets received 20 million ARB from a multisig wallet possibly linked to Gelato Network. Subsequently, GSR moved millions of ARB across Binance and internal addresses, including several large transfers. In parallel, Anchorage Digital transferred 50.1 million ARB to Wintermute’s hot wallet over two weeks. These flows were mirrored precisely, with identical ARB values shifted between custody and operational wallets. Wintermute then distributed millions more to a single receiving wallet, which now holds 77.12 million ARB, ranking as the 13th-largest ARB holder.

Despite the heavy on-chain activity, major trading firms have been selling into the strength. Wallets linked to Paradigm, Teneo, or DeFiance Capital deposited 63.27 million ARB to Binance, Bybit, and OKX since June 14. These transfers included multiple million-dollar moves, often sent in rapid batches. For instance, a June 17 move saw 1.516 million ARB hit Bybit, while 500,000 ARB was routed to OKX at the same minute. Additional deposits of 4 million ARB and 3.5 million ARB followed shortly after, further confirming profit-taking behavior from major investors.

Despite the sell pressure from major funds, Arbitrum’s on-chain metrics remain robust. Daily app revenue reached $137 million, while chain revenue hit $12.6 million. With over 421,000 active addresses, $ARB continues to show high engagement and capital rotation across decentralized finance (DeFi).
