CME Group stock gains while data revenue grows

CME Group stock (ISIN not provided) was quoted at USD 270.80 on Nasdaq in after-hours trading on September 23, 2026, up USD 3.59 or 1.34 percent from the prior close. The move leaves the exchange operator 17.73 percent below its 52-week high of USD 329.16.

Data revenue reaches USD 238 million

The latest operating data point to a second growth engine beyond transaction fees. According to Yahoo Finance, CME Group generated USD 238 million from market-data and information services in the second quarter of 2026, a 20 percent year-over-year increase.

The comparison matters because market-data revenue is less directly tied to daily trading volumes than transaction charges. The same second-quarter review says CME Group paid USD 468 million in regular dividends and repurchased USD 695 million of stock during the period, putting capital returns ahead of market-data revenue in absolute dollars.

Open interest climbs to 127 million

CME Group also entered the second half of 2026 with higher participation. Open interest stood at 127 million contracts in the first half of 2026, up 8 percent year over year, while average daily volume increased 10 percent, according to Yahoo Finance.

That combination gives the stock two measurable supports: contract activity expands the core marketplace, while data subscriptions add recurring revenue. As of June 30, 2026, CME Group had USD 2.3 billion in cash and USD 3.4 billion in debt, according to the same second-quarter coverage.

Third-quarter date is set

MarketScreener lists October 21, 2026, as the scheduled release date for CME Group's third-quarter 2026 earnings. That report will show whether the 20 percent market-data growth and 8 percent open-interest increase are carrying into the next reporting period.

Stock remains below yearly high

The CME Group after-hours quote stood at USD 270.80 on Nasdaq on September 23, 2026, at 4:00 p.m. ET. Its 52-week range was USD 218.31 to USD 329.16, while market capitalization was USD 97,374,068,753.
