Interactive Brokers
4 legal entities are on file for this firm, across 4 jurisdictions. The strongest supervision on file is Tier 1.
Verified means: At least one entity in this firm's structure was located on a tier-1 authority's own public register at the date of the last check, and the entity a retail client is onboarded to is covered by it.
Live tier-1 supervision: SEC/CFTC/NFA, FCA, Central Bank of Ireland, ASIC.
A group can hold a tier-1 licence and still onboard you through an offshore entity in the same structure. The licence protects clients of the entity that holds it — not every client of the brand. Check which company name appears on your own client agreement, then look that company up in the table below.
