The short answer
Based on strong regulation and a high Trust Score, Interactive Brokers shows the hallmarks of a legitimate broker. "Legit" is not the same as "risk-free", though — trading itself can still lose your money.
Regulation & legitimacy signals
A US public company (Nasdaq: IBKR) with entities regulated by SEC/FINRA/CFTC (US), FCA (UK), IIROC (Canada), MAS (Singapore), ASIC (Australia), the Central Bank of Ireland, and others. One of the most regulated & financially transparent brokers.
Green flags & red flags
- Top-tier regulation & transparency — a US public company (Nasdaq: IBKR) supervised by SEC/FINRA/CFTC + many global regulators
- Among the cheapest costs in the industry; very broad global market access
- Very powerful TWS platform & API for professional/algorithmic traders
- The TWS platform has a steep learning curve — less beginner-friendly
- Customer support is more self-service (not hand-holding), suited to technical users
- Interface & account structure can feel complex at first
Risk & regulation note
IBKR is one of the most strongly regulated & capitalized brokers (a US public company since 1978). Leveraged/derivative trading remains high-risk; the TWS platform has a steep learning curve for beginners.
How to verify Interactive Brokers yourself
- 1Check the regulator's database
Look up Interactive Brokers's license number directly on the regulator's official website (e.g. FCA, ASIC, CySEC, CFTC). A real license appears in the regulator's public register.
- 2Confirm the entity that serves your country
Many brokers use different legal entities per region — a tier-1 license in one country may not cover you. Check which entity you're signing up with.
- 3Search for withdrawal complaints
Look for consistent, credible reports of withdrawal problems (not one-off angry posts). Test with a small deposit and a withdrawal before committing more.
- 4Verify the official domain
Only use the official site (interactivebrokers.com). Scammers clone broker sites — check the exact URL and avoid links from unsolicited messages.
