Multiple accounts maintained in the same name and taxpayer ID number are grouped for purposes of applying the maximum per client protection limits of $500,000 by SIPC and $29.5 million under Lloyd’s supplementary protection. However, if you hold accounts with IBKR in separate capacities (for example, an account in your name, a trust account of which you are the trustee or a beneficiary, or a joint account), then each account would be protected by SIPC and the supplementary protection up to the stated limits.
