CI vs CME Comparison

Cigna primarily provides pharmacy benefit management and health insurance services. Its PBM and specialty pharmacy services, which were greatly expanded by its 2018 merger with Express Scripts, are mostly sold to health insurance plans and employers. Its largest PBM contract is the Department of Defense, and it recently won a deal with top-tier insurer Centene. In health insurance and other benefits, Cigna mostly serves employers through self-funding arrangements, and the company operates mostly in the US with 17 million US and 2 million international medical members covered as of September 2024.

Based in Chicago, CME Group operates exchanges giving investors, suppliers, and businesses the ability to trade futures and derivatives based on interest rates, equity indexes, foreign currencies, energy, metals, and commodities. The Chicago Mercantile Exchange was founded in 1898 and in 2002 completed its IPO. Since then, CME Group has consolidated parts of the industry by merging with crosstown rival CBOT Holdings in 2007 before acquiring Nymex Holdings in 2008 and NEX in 2018. In addition, the company has a 27% stake in S&P Dow Jones Indices, making the Chicago Mercantile Exchange the exclusive venue to trade and clear S&P futures contracts. Through CME's acquisition of NEX, it also expanded into cash foreign exchange, fixed-income trading, and collateral optimization.
