Fraudulent Websites, Applications, Social Media, Emails and Texts

As the world's go-to derivatives and exchange network, Cboe is often impersonated and its brand is used by malicious actors to give an air of legitimacy in connection with fraudulent scams. There are many forms that fraudulent scams can take including impersonating the Cboe brand via fake websites, software applications, social media posts, emails, and texts. This webpage provides information about activities Cboe does not conduct and describes other red flags that indicate fraudulent activity. If you are solicited on these types of topics or if you question the legitimacy of a solicitation, you may contact Cboe Site Inquiries at csi@cboe.com. Legitimate Cboe websites use “cboe” in their URLs and a list of these Cboe websites is located here. When evaluating whether a website is legitimate, pay close attention to the spelling of “Cboe.” You can also hover over any purported Cboe website link that you encounter to see if a different link is encoded and will take you to a different (and likely imposter/fraudulent) website.

Cboe does not publish lists or updates regarding non-Cboe websites, domains, and other activity confirmed to be fraudulent or currently under investigation. If you believe you have encountered a fraudulent website, software application, social media post, email text, or individual impersonating Cboe or have a question about whether a website or other activity is a legitimate Cboe website or activity, please contact Cboe Site Inquiries at csi@cboe.com. We will review your inquiry and respond accordingly.

Important Facts You Should Know

  • Cboe does NOT directly solicit retail investors to open trading accounts because Cboe does not maintain trading accounts for retail investors.
  • Cboe does NOT make unsolicited contact with individuals via email, text, or social media to offer or suggest investment opportunities.
  • Cboe does NOT take money directly from individual investors. If someone claiming to be with Cboe asks for money via wire transfer, cryptocurrency, or gift cards, it is fraudulent.
  • Cboe does NOT provide money to individual investors for trading on its markets.
  • Cboe executives will never contact you directly to trade on Cboe’s market or request personal financial information.

Red Flags of Fraudulent Activity

  • Unsolicited Contact: Be cautious of any message you did not request or expect. Scammers often initiate contact via email, text, or social media, posing as legitimate organizations to gain your trust. Cboe will never send you unsolicited messages.
  • Poor Spelling or Grammar: Messages riddled with spelling mistakes, grammatical errors, or awkward phrasing are a strong indicator that the message did not originate from a credible source.
  • Suspicious or Unusual Domain Extensions: Be wary of websites using uncommon domain extensions such as .xyz, .click, or .top in place of the standard .com. Cboe does not use those domain extensions.
  • Impersonation of Cboe Executives: Fraudulent actors may claim to be a Cboe executive or senior leader to establish credibility. Cboe executives and Cboe personnel will not solicit personal information or investment funds.

Additional Guidance
