Robinhood launched using Arbitrum tech, joining the Arbitrum stack (Orbit).
Yet $ARB has only barely bounced back from its ATL 7 days ago.
Massive win for Arbitrum from technical, reputational, and BD perspective but also from liquidity via Orbit but market doesn't care.
Years ago this would've pumped $ARB significantly.
But market now requires fruits from this partnership, ideally increased fees that accrue to $ARB.
At least Robinhood paid $1M to Arbitrum’s Open House 2026 program.
It's also a win for Ethereum:
Instead of Robinhood building their own corpo-slop L1, Robinhood stays within the Ethereum ecosystem with some fees being routed to the L1.
So Ethereum L2 roadmap didn't go to waste despite liquidity fragmentation and worse UX in the short run.
