Robinhood is planning to launch a blockchain-based US stock trading platform, potentially using Arbitrum or Solana technology to build a dedicated L2 chain. The company has obtained a brokerage license in the EU and plans to expand its crypto derivation business through the acquisition of Bitstamp. CEO Vlad Tenev has previously mentioned the concept of securities tokenization multiple times, aiming to address the pain points for overseas investors trading US stocks. Market speculation suggests that Robinhood will announce related plans at the EthCC conference on the 30th, with Arbitrum's Chief Strategy Officer also attending, sparking collaboration associations. This move is seen as a competitive response to Coinbase's Base chain, but analysts suggest that Robinhood should leverage its brokerage advantages to pursue a closed ecosystem approach. The ARB token's 24-hour rise once surpassed 20%, reflecting the market's positive expectations for this collaboration.
