Interactive Brokers Group Inc (IBKR) Stock Split History

Interactive Brokers Group Inc has split its stock once since its initial public offering (IPO). The stock split of Interactive Brokers Group Inc occurred on June 18, 2025 on a 4-for-1 basis, meaning that for 1 share of IBKR owned pre-split, shareholders then owned 4 shares.

This action has increased the stock's liquidity and made it more appealing to a larger group of investors. However, it's important to remember that a stock split only changes the number of shares and the price per share with no impact on Interactive Brokers Group Inc's total market capitalization.

The answer will depend on the decisions of the company's managers and market volatility. Interactive Brokers Group Inc has not made an official announcement regarding whether it will enact a stock split or reverse stock split, but it has a history of doing so when IBKR stock prices become too high or too low for retail investors. Therefore, the ultimate decisions will certainly be made by Interactive Brokers Group Inc's board of directors. Typically, no action is taken until its price per share reaches a specific threshold.
