REPORTS INCOME BEFORE TAXES OF $545 MILLION ON $1.1 BILLION IN NET REVENUES, EARNINGS PER SHARE OF $0.87

GREENWICH, CONN, January 21, 2010 — Interactive Brokers Group, Inc. (NASDAQ GS: IBKR) an automated global electronic market maker and broker, today reported diluted earnings per share of $0.87 for the year ended December 31, 2009, compared to diluted earnings per share of $2.24 in 2008.

Net revenues were $1,100 million and income before income taxes was $545 million for the year, compared to net revenues of $1,850 million and income before income taxes of $1,250 million in 2008.

Business Highlights

• 50% pre-tax profit margin for 2009.

• 49% Electronic Brokerage pre-tax margin for 2009.

• Customer equity grew by 71%, to $15.2 billion from prior year and customer accounts grew by 21%.

• Cleared DARTs were 316,000 in 2009, even with the prior year.

• Market Making pre-tax income decreased 68% from the prior year.

• 53% Market Making pre-tax profit margin for 2009.

"In 2009, as a consequence of the credit crises, risk aversion has greatly increased among institutional traders," said Thomas Peterffy, our CEO. “The resulting high option premiums, which we need to pay as part of our hedging costs, were difficult to make up for with trading profits in an environment of shrinking spreads and diminishing volumes.

We have nevertheless, escaped the crises without any losses. As the largest publicly traded non-bank, Broker-Dealer, with equity capital of $4.9 billion, we are well positioned to continue building our business in a strengthening world economy."

Segment Overview

Electronic Brokerage

Electronic Brokerage segment income before income taxes grew 3% in 2009. Customer accounts grew 21% from the prior year and customer equity increased 71% during 2009, partly offset by reduced customer trading activity. Net interest income declined 27% due to the historically low benchmark interest rates. Pre-tax profit margin was 49% for 2009. Total DARTs* for cleared and execution-only customers decreased 3% to 347,000 in 2009, compared to 357,000 during 2008, which was an extraordinarily turbulent year in the markets. Cleared DARTs were 316,000 in 2009, even with the prior year.

Market Making

Market Making segment income before income taxes decreased 68% in 2009. Pre-tax profit margin narrowed to 53% in 2009 from 77% in 2008. Low market volatility, compressed bid/offer spreads in options and heightened competition reduced the trading opportunities for our automated market making system. In the latter part of 2009, the ratio of implied to actual volatility was relatively high, making it expensive to maintain our desired hedged position. We continued to avoid counterparty risks and balance sheet exposure from illiquid positions by making markets primarily in exchange-traded products that are cleared through central clearing houses. Market Making options contract volume decreased by 17% and futures volume decreased by 30% in 2009.

*Daily average revenue trades (DARTs) are based on customer orders.

** In Brazil, an equity option contract typically represents 1 share of the underlying stock; however, the typical minimum trading quantity is 100

      contracts. To make a fair comparison to volume at other exchanges, we have adopted a policy of reporting Brazilian equity options contracts

      divided by their trading quantity of 100.
