FTC endorsement rules.

The Federal Trade Commission (FTC) enforces consumer protection laws that apply to anyone who is paid to promote a product or service on social media — including college and high school athletes. Since NIL opened, hundreds of athletes have become social media influencers. These rules govern every sponsored post, gifted product, and paid appearance you promote online.

The FTC's primary regulation is the "Guides Concerning the Use of Endorsements and Testimonials in Advertising," substantially updated in 2023 and supplemented by new AI-endorsement guidance in May 2026. Violations can result in civil penalties of up to $53,088 per violation (2025 inflation-adjusted amount; the 2026 annual adjustment was cancelled due to a government appropriations lapse). The FTC has also begun holding individual influencers — not just brands — liable.

You must disclose a material connection with a brand whenever you post about them if a "material connection" exists. A material connection includes:

• •Cash payment (sponsored post, ambassador deal, per-post fee)
• •Free products, merchandise, or gear (even if no money changed hands)
• •Discounts offered exclusively to you as a brand partner
• •Family or employment relationships with the brand
• •Equity or ownership stake in the company

The FTC requires disclosure when the connection is not already "reasonably expected" by the audience. If you are a paid athlete ambassador for a shoe brand and you post wearing their shoes, you must disclose — even if you "genuinely love the product."

The FTC requires disclosures to be:

• •Clear: Easy to understand and unambiguous
• •Conspicuous: Not buried in hashtags, and not below the fold where viewers must click "more" to see it
• •Close to the claim: Near the beginning of the post or caption, not only at the end

Each social media platform has its own branded content policies in addition to FTC requirements. Using a platform's built-in disclosure tool does NOT replace your obligation to comply with FTC rules.

The FTC's 2023 updates specifically target fake or misleading reviews. For athletes:

• •You cannot provide a positive testimonial for a product you have not personally used
• •You cannot make claims about a product's performance that are not substantiated (e.g., "This supplement added 5 mph to my fastball" must be verifiable)
• •You cannot set up, fake, or incentivize reviews for a brand on third-party platforms (Amazon, Google, Yelp)
• •You should share your honest opinion — the FTC does not require your review to be positive, only honest
• •If you were given a product for free on the condition of a positive review, the disclosure must reflect that condition

The 2023 updates also specifically target "dissociated endorsements" — where brands use your likeness after your deal ends without your current endorsement.

The FTC's 2023 revisions first addressed AI-generated content, and the May 2026 supplemental guidance significantly expanded the framework. The FTC has also revised the definition of "endorser" in the Endorsement Guides to include "what appears to be an individual, group, or institution" — meaning AI-generated, fabricated, or synthetic endorsers are subject to the same disclosure, substantiation, and material-connection rules as real endorsers.

For athletes, this is increasingly relevant:

• •Brands may not use AI-generated versions of your name, face, or voice in advertising without your explicit consent
• •If a brand uses deepfakes or AI voice/image synthesis to suggest you endorse a product, they are violating FTC rules — and potentially your Right of Publicity
• •If you use AI-generated content in a sponsored post (AI-written captions approved by a brand, AI-edited images), disclosure is still required
• •Virtual influencer accounts controlled by brands but impersonating real athletes are an FTC enforcement target
• •An AI-generated endorsement must comply with the same disclosure, substantiation, and material-connection requirements as a traditional endorsement (May 2026 FTC guidance)
• •Brands and creators using AI tools must ensure audiences are not misled into thinking a real person provided the endorsement — synthetic media use requires affirmative disclosure
• •In 2024 the FTC filed complaints against multiple supplement companies for using AI-generated celebrity testimonials — this is an active enforcement area

The FTC has increased enforcement actions against individual influencers since 2022. Key enforcement facts:

• •Civil penalties: Up to $53,088 per violation (2025 inflation-adjusted; 2026 adjustment cancelled by OMB)
• •The FTC first issues warning letters, but has escalated to formal enforcement orders
• •Individual influencers — not just brands — can be personally fined
• •The FTC has specifically named athlete influencers in warning campaigns
• •The FTC monitors social media for compliance and can investigate based on public complaints

Actions the FTC has taken include:

• •Sent warning letters to dozens of celebrity and athlete influencers
• •Issued formal enforcement orders to brands using undisclosed influencer networks
• •Published the "Endorsement Guides" updated October 2023
• •Issued supplemental AI-endorsement guidance in May 2026 addressing synthetic influencers, AI-generated testimonials, AI-edited creator content, and deepfake endorsements
• •Filed complaints in 2024 against multiple supplement companies for using AI-generated celebrity testimonials

Best practice: treat every sponsored post as if the FTC is reviewing it.

NIL deals often involve social media obligations. Every NIL contract that includes social media posting requirements should be reviewed for FTC compliance. Common NIL contract scenarios and what they require:
