Deepfake Celebrity Investment Ads: How to Spot a Fake Endorsement Before You Invest

How a fake endorsement is built

The pattern is simple. An ad or post shows a famous person, often a business figure, presenter or sportsperson, apparently praising an easy way to make money. It might be a still image with a quote, a clip with a cloned voice, or a news-style article that appears to quote them. A button leads to a polished site where you leave your phone number and a small deposit.

The FBI’s December 2024 public service announcement describes the raw materials. It says criminals use AI-generated images of celebrities or personas to promote counterfeit products or non-delivery schemes, and fake promotional videos to support investment fraud. It also lists AI-generated text for fraudulent cryptocurrency and other investment websites. The ad is the hook; the website and the person who calls you afterwards are the trap.

The FTC’s point about endorsements

The FTC’s cryptocurrency scam guidance makes a point that holds even without deepfakes: celebrity endorsements and happy-investor testimonials do not prove an investment is legitimate, because they are easy to fake. It adds that real celebrities do not contact people through social media offering to multiply their crypto, and that clicking an unexpected link or sending crypto to a “celebrity’s” QR code sends your money directly to a scammer.

The FTC also notes that scammers may use social media ads, news-style articles or slick websites to make a fake coin or token look credible, and recommends checking whether established media have reported on it.

Voices and robocalls

The tactic is not limited to video. When the FCC ruled in February 2024 that calls made with AI-generated voices are “artificial” under the Telephone Consumer Protection Act, it said bad actors use such voices in robocalls to imitate celebrities, among other things. If an investment pitch arrives as a call in a famous voice, the same checks apply. See AI voice agents and robocalls for what that ruling does and does not cover.

Red flags that matter more than visual glitches

You may see lip movement that is slightly off or a voice that sounds flat, and our guide to spotting AI-generated images and video explains these. But quality improves, and a crude fake can still work on a distracted viewer. The FTC’s investment red flags are more reliable:

• Guarantees that you will make money, or “zero risk” claims.
• A contact from an unexpected “investment manager” urging you to buy crypto and transfer it to them.
• Vague explanations of how the investment works and where your money goes.
• A dashboard that shows large gains but you cannot withdraw, or can only withdraw after paying high fees.

The FTC says investment scams often begin on social media or dating apps. The same operators may also run relationship schemes, covered in AI romance chatbots and scam bots and the investment scams guide.

How to check before you pay

1. Ignore the ad and look up the person’s own verified account or recent interviews. If they truly backed a product, it will be reported by established outlets.
2. Search the company or coin name together with “review”, “scam” and “complaint”, as the FTC suggests.
3. Check whether the firm is registered with your national financial regulator before depositing anything.
4. Use only your own bookmarked link to a platform, never the ad’s link.
5. Pay nothing in crypto to an address someone sends you.

Where the law stands

The FTC’s Impersonation Rule took effect on April 1, 2024. According to the FTC’s announcement, it gives the agency stronger tools to deter scammers who impersonate government agencies and businesses, and the FTC took comments on a supplemental proposal to cover impersonation of individuals. A rule helps with enforcement after the fact, but advertisers behind these schemes are often hard to identify, so your own checks come first.

If you already paid

Contact your bank or card issuer, stop sending money, and save screenshots of the ad, the site and any chats. Report at ReportFraud.ftc.gov or ic3.gov, and tell the platform that carried the ad. Expect a follow-up from someone promising to recover your funds; that is a known second-stage scam, described in our recovery scams guide.
