Ethereum Layer-2 network Arbitrum (ARB) has captured market attention after a 17% price jump, fueled by speculation of a potential partnership with Robinhood Markets. The buzz follows a social media teaser from Robinhood indicating a major crypto-related announcement.
Fireside Chat Sparks Rumors of Arbitrum-Robinhood Collaboration
Over the weekend, Robinhood posted that a fireside chat featuring Ethereum co-founder Vitalik Buterin, Robinhood Crypto General Manager Johann Kerbrat, and Offchain Labs Chief Strategy Officer A.J. Warner will take place Monday. The event, hosted by Robinhood Europe in Cannes, France, is being promoted as the company’s “biggest crypto announcement of the year.”
This led many to believe that Robinhood is preparing to reveal a partnership or integration with the Arbitrum network.
Offchain Labs, the core developer behind Arbitrum, has not confirmed any formal agreement. However, the presence of both Robinhood and Arbitrum leadership at the same event has driven intense speculation.

Earlier Leaks Pointed to Blockchain Expansion
Back in May, reports emerged that Robinhood was exploring the launch of a blockchain-based platform to allow European investors to trade U.S. stocks. At the time, both Arbitrum and Solana were being considered for the blockchain infrastructure.
The recent developments suggest Robinhood may have chosen Arbitrum over other contenders.
Former Ethereum core developer Eric Connor fueled the rumors further, posting on X: “Looks like Robinhood chose Arbitrum.” Meanwhile, Omar Kanji, a venture partner, added that this might mean “Robinhood is about to announce its own chain,” potentially powered by Arbitrum technology.
Arbitrum Leads Crypto Market in Daily Gains
The ARB token rose from $0.31 to a high of $0.386 within eight hours after the Robinhood post, marking a 17.1% daily increase. Despite the recent surge, ARB remains down nearly 50% in 2025 and has lost over 85% from its January 2024 high of $2.39.
Still, it was the top-performing crypto asset in the last 24 hours.
Robinhood Stock Also Sees a Boost
Amid the excitement, Robinhood’s stock (HOOD) climbed by 1.65% in overnight trading, reaching $84.26, up from Friday’s close of $83.03.
A High-Stakes Week for Arbitrum and Robinhood
As anticipation builds ahead of Monday’s event, both the Arbitrum community and crypto markets are bracing for what could be a pivotal partnership announcement. If confirmed, the integration could signal a major step in the mainstream adoption of Ethereum Layer-2 scaling solutions.
