Legal Guide for Sweepstakes, Contests and Giveaways
Ensure your sweepstakes cannot be classified as an illegal lottery. A lottery has three elements: a) Prize; b) Consideration; c) Chance. Those elements are interpreted broadly: Consideration can be anything of value, such as liking your Facebook page, writing a comment on your blog, rating a product, subscribing to newsletter or Twitter feed. Chance element is present if winners are chosen predominantly by luck: for example Bingo is a game of chance while Solitaire is a game of skill, even though an element of luck is present in the latter. Using services like random.org or rafflecopter.com clearly establishes the Chance element present.
As you can see, many sweepstakes out there today do not strictly comply with all of these requirements. Violation of the provisions on operation of contests or sweepstakes is a misdemeanor in California (Bus. & Prof. Code §17534) and other states. While the prosecution for a small time website giveaway is not very likely, a common design move is to take out one of the three elements: entrants are not required to do anything of value, or winners are chosen by showing some merit or skill such as winning a game or contest. Removing one of the three lottery elements may take the promotion out of the classic illegal-lottery structure, but it does not automatically make the promotion lawful. The promotion still has to comply with state sweepstakes statutes, registration and bonding rules, advertising law, platform rules, tax reporting, privacy law, AI disclosure and substantiation rules, and any gaming-specific restrictions.
There are also state-specific rules. For example, in New York a sponsor must bond prizes valued above $5,000 or establish and maintain a special trust account with a balance sufficient to cover the total value of prizes offered. Florida also requires a surety bond for any sweepstakes with a prize value of more than $5,000.
The following will help ensure compliance and prevent misunderstandings:
a. Post sweepstakes official rules and link to them in announcements.
b. Promotion Period - start and end date.
c. “No purchase necessary.”
d. “Odds of winning depend on number of entries.”
e. “Entries that are not accompanied by orders are treated the same as entries that are accompanied by orders.”
f. Eligibility for entry (“Open to legal US residents 18 years of age or older.”)
g. How to enter and what is the maximum number of entries per person.
h. Dollar value of the Prize.
i. The maximum amount of money, including postage and handling fees, which a participant may be asked to pay to win each of the prizes offered.
j. Avoid prizes involving tobacco, alcohol, gasoline, insurance or financial services.
k. How are ties and unclaimed prizes handled?
l. Prize to any one person worth $600 or more requires you to file Form 1099 with the IRS.

How AI changes this analysis
Artificial intelligence does not replace the analysis above. A lawful promotion still needs the same prize, chance, and consideration review. What AI changes is the factual side. A promotion gets more complex when AI is used to select winners, judge entries, personalize offers, screen fraud, generate promotional content, create winner testimonials, or decide eligibility or disqualification. An AI tool that only drafts internal marketing copy raises different issues than an AI model that ranks entries, assigns scores, or decides whether a participant gets a bonus.
Two wrinkles matter most. First, on the chance side: if your contest relies on an AI image or text generator, the same prompt can produce different outputs, so chance can creep in through the generation layer even when the judging looks objective. Making an AI judge deterministic does not help if the generation step still injects randomness into the player's output. Second, on the truthfulness side: regulators generally treat AI-assisted deception the same as any other deception, so AI-generated fake reviews, synthetic winner stories, and fictional testimonials carry the same exposure as any other false advertising. AI-generated promotional media may require disclosure depending on the jurisdiction, platform, claim context, and whether the content could mislead consumers into believing it depicts a real winner, endorser, event, or product experience, and a growing number of states are adding AI-disclosure and automated-decision requirements. This is legal information, not legal advice, and how it applies depends on your specific facts.
If AI selects winners, judges entries, or generates the work that gets scored, document the model or tool used, the role AI plays, whether a human can review the result, how selection or judging is audited, whether AI-generated content is disclosed, whether entrant submissions may be used for AI training, and whether any claim about AI accuracy, fairness, or objectivity can be substantiated.
When to have an attorney look at it
This guide is general legal information, not legal advice, and it does not create an attorney-client relationship. Whether a specific promotion is a lawful contest or sweepstakes, or crosses into an illegal lottery, depends on the exact mechanics, the prize value, and the states you run in. Because AI-judged contest legality depends on the exact mechanics, I do not give skill-versus-chance reactions on informal unpaid calls. The entry point is a $240 written screen that identifies the likely classification, the key chance arguments, the target-state issues, and the design changes to make before you invest in a full opinion letter.
