SoFi Buys Composer and Launches AI Platform for Natural-Language Trading

SoFi says the new tool will boost member engagement by letting users build, test and automate rules-based strategies using plain-English prompts.

Overview

  • SoFi announced on Tuesday that it has acquired AI startup Composer and launched Composer by SoFi, a platform that turns plain-English investment ideas into testable, rules-based trading strategies.
  • The platform lets retail users create strategies without coding, backtest those strategies against historical market data, automate execution, and browse a library of more than 2,000 community-created strategies.
  • SoFi said core Composer features will roll out to all members this summer, with advanced functionality gated behind its SoFi Plus subscription and broader integration across the app planned over the next 12 months; the company did not disclose deal terms.
  • CEO Anthony Noto framed the effort as giving everyday investors institutional-style tools while keeping users in control, saying AI converts ideas into rules rather than making independent decisions.
  • The launch puts SoFi alongside brokerages adding AI tools such as Robinhood and Coinbase and could raise engagement and subscription revenue while prompting questions about transparency, guardrails and how well AI strategies work in live markets.
