Interactive Brokers is the platform I use, and if it is the one that fits you best, opening the account through my referral link is strictly better than signing up from the homepage:

  • Free IBKR stock for you. Under IBKR’s Refer-a-Friend program, a referred client earns $1 worth of IBKR Class A common stock for every $300 in net deposits in the first year, up to $1,000 worth of shares. None of the other brokers in this comparison hand you equity for showing up.
  • Trackable rewards. Your “Welcome Share Balance” updates daily inside the account as you fund it, so the reward is visible rather than a promise.
  • No cost to you. Commissions, margin rates, market access, and platform features are identical to a direct signup - the referral only adds the welcome shares.
  • It supports this blog. IBKR pays me a referral fee on qualifying accounts, which keeps these broker comparisons and options guides free.

Ready to open an account? Join me on Interactive Brokers for access to 150+ global markets, advanced options tools, and futures in one account.

Reward amounts and eligibility rules are set by Interactive Brokers and can change, so check the current Refer-a-Friend terms before funding. This is a referral link, not investment advice.
