The stock of online brokerage Interactive Brokers Group (IBKR) is being added to the benchmark S&P 500 index, replacing Walgreens Boots Alliance (WBA).
S&P Dow Jones Indices announced the change, which will take effect when markets open on Aug. 28.
Interactive Brokers is replacing Walgreens Boots Alliance, which is being taken private by Sycamore Partners and whose stock will soon be delisted.
Interactive Brokers' shares rose 5% in after-hours trading on news of its inclusion in the S&P 500 index.
Stocks typically rise when added to the S&P 500 as mutual funds and exchange-traded funds (ETFs) that track the index are required to buy the shares.
Currently trading at $62.76 U.S. per share, IBKR stock has doubled over the last 12 months and is up 38% so far in 2025. The stock split on a 4-for-1 basis in June of this year.
The decision to add Interactive Brokers to the S&P 500 came as a bit of a surprise as many on Wall Street expected Robinhood Markets (HOOD) to be added to the index.
Robinhood's stock has gained 415% in the last 12 months and the company has a market capitalization of $96 billion U.S. currently.
Talen Energy (TLN) will replace Interactive Brokers in the S&P MidCap 400 index on Aug. 28. The electricity producer's stock rose 3% in extended trading on that news.
S&P Dow Jones Indices typically make changes to its indices once per quarter. However, it also makes changes on an as needed basis when stocks such as Walgreens delist or are removed.
