CME Group Explained — The World’s Largest Futures Exchange
What Is CME Group?
CME Group was formed through a series of mergers, starting with the combination of the Chicago Mercantile Exchange and the Chicago Board of Trade in 2007, followed by the acquisition of NYMEX/COMEX in 2008. Today it’s a publicly traded company (ticker: CME) and operates as the central hub for global futures trading.
While the NYSE and Nasdaq deal primarily in stocks, and Cboe focuses on options, CME Group’s specialty is futures contracts — standardized agreements to buy or sell an asset at a predetermined price on a future date. These contracts are used by everyone from farmers hedging crop prices to banks managing interest rate exposure to hedge funds speculating on oil.

How Do Futures Exchanges Work?
CME Group operates as a central counterparty through its clearing house, CME Clearing. When two parties trade a futures contract, CME Clearing steps in as the buyer to every seller and the seller to every buyer — eliminating counterparty credit risk. This is what separates exchange-traded derivatives from over-the-counter ones.
Traders must post margin (collateral) to hold positions, and positions are marked to market daily. If your position moves against you, you’ll receive a margin call requiring additional collateral. This system ensures that no single participant’s default can cascade through the market.

Why CME Group Matters to Stock Investors
Even if you never trade futures, CME Group affects you. The E-mini S&P 500 futures contract (ES) is what drives overnight stock market moves. When you hear “futures are up” before the market opens, that’s CME Group. These futures trade nearly 24 hours a day on CME’s Globex electronic platform, providing continuous price discovery even when the NYSE and Nasdaq are closed.
Treasury futures on CME are the primary instrument for trading interest rate expectations — they move Treasury yields, which in turn affect everything from mortgage rates to stock valuations.

Frequently Asked Questions
What is the difference between CME Group and the stock market?
The stock market (NYSE, Nasdaq) primarily trades shares of companies. CME Group trades futures and derivatives — contracts based on underlying assets like indexes, commodities, interest rates, and currencies. You don’t buy or sell company shares on CME; you trade contracts that derive their value from other assets.
Can retail investors trade on CME Group?
Yes. Retail investors can trade CME products through futures-approved brokerage accounts. Products like Micro E-mini S&P 500 futures (1/10th the size of the E-mini) were specifically designed for retail traders, requiring margin deposits as low as ~$1,300 per contract.
What are E-mini and Micro E-mini futures?
E-mini contracts are electronically traded, smaller-sized versions of standard futures. The E-mini S&P 500 (ES) is worth $50 × the S&P 500 index value. The Micro E-mini (/MES) is 1/10th that size ($5 × the index value). Micros make futures accessible to smaller accounts while still providing leveraged exposure to major indexes.
What is CME Globex?
CME Globex is CME Group’s electronic trading platform, launched in 1992 as one of the first global electronic futures trading systems. It operates nearly 24 hours a day, 5 days a week (Sunday 6:00 PM ET to Friday 5:00 PM ET, with a daily maintenance break). Globex handles the vast majority of CME Group’s trading volume.
Why did oil futures briefly go negative in 2020?
In April 2020, WTI crude oil futures on NYMEX (part of CME Group) dropped to -$37.63 per barrel — a historic first. This happened because COVID lockdowns destroyed demand, storage facilities were nearly full, and traders holding expiring futures contracts faced the prospect of taking physical delivery of oil with nowhere to put it. They paid others to take the contracts off their hands, driving the price below zero.
