IBKR
Interactive Brokers Group, Inc.
An automated electronic brokerage serving individual investors, advisors, and hedge funds, Interactive Brokers lets clients trade stocks, options, futures, forex, bonds, and crypto from one platform through tiers like IBKR Pro and commission-free IBKR Lite. It traces back to Hungarian immigrant Thomas Peterffy, who started as a market maker in 1977 and later turned his Timber Hill trading systems into an outside brokerage in 1993. A technology pioneer, Peterffy built what is considered the first handheld computer for trading floors.
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -3.51M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
