CME Group Cookie Notice

Effective: November 17, 2023

At CME Group Inc. and each of its subsidiaries and affiliates (collectively known as 'CME Group', 'we' and 'us'), we believe in being clear and transparent about how we collect and use information about you or related to you. In the spirit of transparency, this Cookie Notice (the “Notice”) provides detailed information about how and when we use cookies (and similar technologies). This Notice applies to any CME Group website, application or service that links to this Notice or incorporates it by reference.

Cookies are text files containing small amounts of information, and other similar technologies, which are used to collect and store information from your device when you visit a website ("Site"), use applications, or utilize other offered services. Cookies we use may be stored on your computer or device when you interact with CME Group and our Sites. For example, cookies enable us to identify your device, secure your access to our Sites, understand how users interact with us and provide tailored advertising.

Permanent cookies (also known as persistent cookies) remain on your computer until they expire or you delete them. Temporary cookies (also known as session cookies) last until you close your browser. CME Group Sites use first-party and third-party cookies. First-party cookies are created and stored directly by CME Group. Third-party cookies are created and stored by a third party.

As described in our Privacy Notice, we use cookies for various purposes, subject to your prior consent where applicable, including to better serve your particular needs, promote our services and to help us protect your account.

Cookies can be used to recognize you when you visit our Sites, remember your preferences, and give you a personalized experience. Cookies also make your interactions with CME Group faster and more secure. Additionally, cookies allow us to deliver advertising to you both on and off the CME Group Sites.

We use five types of cookies: strictly necessary cookies, performance cookies, functional cookies, targeting cookies, and social media cookies.

  • Strictly necessary cookies are necessary for the website to function and enable you to fully experience our services. These cookies make the features and functionalities found on these services available to you. CME Group uses this type of first-party cookie to handle user registration and login, and if they receive error messages from web pages. These cookies cannot be switched off in our systems and are not subject to your prior consent. You can set your browser to block or alert you about these cookies, but subsequently some parts of the Site will not work.

  • Performance cookies collect information about how users interact with our services, including which pages visitors go to most often, and if they get error messages from certain pages. We use these third-party performance cookies to provide statistics on how our services are used and to measure delivery and performance of our campaigns. These cookies help us learn how well our services and plugins perform in different locations. We also use these cookies to understand, improve, and research products, features, and services, including when you access CME Group from other websites, applications, or devices such as your computer or your mobile device.

  • Functional cookies provide enhanced functionality and personalization. They allow our Sites to remember choices you make (such as your username, language, email settings, and other settings) and provide enhanced, more personalized features. They may be set by us or by third-party providers whose services we have added to our pages. You may opt-out of these cookies, but some or all of these services may not function properly.

  • Targeting cookies may be set through our Site by our advertising partners. They may be used by those companies to build a profile of your interests and show you relevant advertisements on other sites. They do not directly store personal information, but are based on uniquely identifying your browser and internet device. If you do not allow these cookies, you will experience less targeted advertising.

  • Social Media cookies are used by social media services to enable you to share our content with your friends and networks. These cookies may track your browser across other sites and build a profile of your interests, which may impact the content and messages you see on other websites that you visit.

Refer to Section 9 of the CME Group’s General Privacy Notice regarding our collection, use, disclosure, and retention of your personal information, as well as the rights that California residents may have under applicable law.

To exercise your right to opt out of our “sale” or “sharing” of your personal information and to change your cookie preferences at any time, please visit our Cookie Preference Center.
