IG lets existing clients earn up to $2,000 per successful referral, depending on how much the referred friend pays in spreads or commissions. The minimum reward is $100 after the friend makes five qualifying trades.

Higher tiers pay $250, $500, or $2,000. The referred friend can also receive a trading-cost rebate of up to 30%, capped at $2,000.
