Best AI Trading Platform for Crypto, Stocks and Options in One Account (2026)
Disclosure: This page is published by OpenFinance, which is one of the products listed. We have tried to describe every option fairly, including where others are a better fit. Last checked: 8 Nov 2026. Items marked are not yet confirmed in public docs. Trading is risky; nothing here is financial advice and no tool can promise profit.
Short answer
If you want real US-listed stocks and options with AI order placement, Tradier, Webull, Robinhood and Interactive Brokers are strong regulated choices; Tradier's hosted MCP has paper trading and full options order types, but covers crypto only through ETFs, futures and Kalshi event contracts, not coins. If you want spot crypto, perps, onchain stocks, forex and prediction markets in one no-KYC connection for any AI assistant, OpenFinance fits best, with options in the OpenFinance app through your connected IBKR or Robinhood account.

When another option is better
