Interactive Brokers Group

Interactive Brokers does not earn from management fees on proprietary funds. Its revenue comes overwhelmingly from three sources: net interest income derived from margin loans and cash sweeps, commissions and routing rebates on trade execution, and fees from ancillary services such as market data. The model makes it structurally sensitive to interest rates and trading volume, not to asset-appreciation-based fee streams.

The firm operates distinct account structures for hedge funds, proprietary trading groups, financial advisors, and introducing brokers. Institutional clients access the same core execution infrastructure as retail users but receive specialized middle-office tools, block-trading facilitation through the IBKR ATS, and an outsourced trading desk for large or complex multi-asset orders.

The platform primarily provides access to publicly traded and listed derivative markets. It does offer a hedge fund marketplace for accredited investors and recently introduced prediction markets, but these are marketplace-access functions — Interactive Brokers does not manage commingled private-equity or venture-capital vehicles.

No. The firm acts as a broker-dealer and custodian, executing client-directed trades and holding assets. It does not offer discretionary portfolio management at the parent level; its Interactive Advisors robo-advisory unit provides non-discretionary, goal-based portfolio construction that clients approve.

Interactive Brokers reports over $21 billion in total firm equity, holds client assets in segregated accounts, and carries excess SIPC coverage beyond standard limits through Lloyd’s of London. The firm also runs automated real-time risk controls that liquidate positions when account equity falls below margin thresholds, which it argues protects both the client and the clearinghouse from gap risk.
