Thomas Peterffy, who helped bring computerized pricing to options floors in the 1970s, built the firm into an electronic broker serving professional traders, hedge funds, and self-directed investors across dozens of markets. Automation is the competitive position: the cost to serve an account is low enough to support pricing that full-service brokers cannot match. Margin lending and interest on customer cash produce a large share of profit, making results rate-sensitive. Account growth has come substantially from outside the United States. Headquarters are in Greenwich, Connecticut.

Equity comp at Interactive Brokers

• Interactive Brokers ties RSU vesting to the anniversary of the company's 2007 initial public offering rather than to each employee's individual grant or hire date. Awards vest in installments of roughly 10 percent per year, so a full grant can take about a decade to fully vest, far slower than the 4-year schedule common at most public companies. Because vesting is anchored to a single calendar date each year instead of a personal grant anniversary, employees hired at different times can see their RSU tranches line up on the same annual vest date.
