AI "first," "only," and "best" claims: what should buyers ask?
Last reviewed May 30, 2026
The SEC found Global Predictions misrepresented its AI advisor as the "first regulated" in its category — the comparison set, jurisdiction, and date that would support the claim were never established. The FTC found DoNotPay's "world's first robot lawyer" lacked the comparison evidence needed to substantiate it. Both cases show the same evidence gap behind "first," "only," and "best" AI claims. This page maps those wording patterns to the comparison evidence a buyer should request.
Evidence buyers verify
- A defined market scope: which product category, use case, and geography the first, only, or best claim applies to.
- A named comparison set: which products or services were compared before the claim was made.
- A point-in-time reference: the date the comparison was current, and how the claim is updated if the landscape changes.

Public claims with documented evidence gaps
"first regulated AI financial advisor"
First / Only / Best- Source and date
- SEC Global Predictions administrative order · March 18, 2024
- Evidence signal
- First-of-kind claim combined with a regulatory status claim, without naming the comparison universe, jurisdiction, or date the comparison was checked.
- Evidence gap
- A buyer needs the market definition, the comparison set of registered advisers checked, the jurisdiction for the first claim, the date that comparison was current, and whether the regulatory status existed at the time the claim was public.
- Buyer question
- For the first regulated AI financial advisor claim, what market definition, comparison set, and date support the word first — and which regulator and registration type give it meaning?
"the world's first robot lawyer"
First / Only / Best- Source and date
- FTC DoNotPay final order release · February 11, 2025
- Evidence signal
- World-first claim for a professional-service category, without a defined comparison set or evidence that prior comparable products were checked.
- Evidence gap
- A buyer needs the product categories compared, the date of the world-first comparison, the jurisdictions searched, and the task scope used to define robot lawyer.
- Buyer question
- For the world's first robot lawyer claim, which product categories were compared, on what date, across which markets — and which tasks define robot lawyer for that comparison?
"The Best AI Accounting Solution"
First / Only / Best- Source and date
- ASA/CAP AI as a Marketing Term Report · November 2024
- Evidence signal
- Superlative best combined with an AI descriptor and a product category, without a stated comparison set, criteria, or date.
- Evidence gap
- A buyer needs the products included in the comparison, the criteria used to rank them as best, the date that comparison was current, and a process for updating the claim if a better alternative emerges. The ASA/CAP report found that superlative AI-descriptor combinations routinely lack this comparison basis.
- Buyer question
- For the best AI accounting solution claim, when was the comparison made, which products were included, on what criteria — and is there a stated process for updating this claim if a more capable alternative becomes available?
Match each claim pattern to the evidence buyers need
| Claim pattern | Evidence needed | Buyer question |
|---|---|---|
| "First AI to..." or "world's first" for a product category | Product categories compared, jurisdictions searched, comparison date, task scope used to define the category, and a named source that confirms no prior comparable offering existed. | What comparison set and date support the first claim, and which categories or markets were excluded from that comparison? |
| "Only platform that..." or "only AI that can..." | Feature tested, comparison set, date of comparison, and whether the only claim is limited to a specific use case or applies to all AI products in the category. | What comparison set shows no other platform offers this feature, and is the only claim limited to a specific workflow or use case? |
| "Best," "most advanced," or "industry-leading" AI | Named comparison criteria, comparison set, performance data supporting best, and the date the ranking was current. | What criteria define best, which products were compared, and when was that comparison last updated? |
| "First regulated," "first certified," or "first compliant" AI | Regulator or certifying body, registration type, jurisdiction, date of regulatory status, and comparison set for first. | Which regulator, registration type, and jurisdiction support the first regulated claim, and was that status current when the claim was published? |
Evidence to request
- A defined market scope: which product category, use case, and geography the first, only, or best claim applies to.
- A named comparison set: which products or services were compared before the claim was made.
- A point-in-time reference: the date the comparison was current, and how the claim is updated if the landscape changes.
- For regulated or certified claims: the specific regulator, registration type, and jurisdiction that supports the status claim.
Questions to put in front of the vendor
- What market scope, comparison set, and date support this first, only, or best claim?
- If the claim says first, which categories and jurisdictions were excluded from that comparison?
- If the claim says best, what criteria determine best, and which products were measured against those criteria?
- If the claim says only, is that claim limited to a specific feature, workflow, or deployment context?
- How does the vendor update this claim if a competitor launches a comparable offering?
Wording boundaries to compare against
- Currently the only [product category] offering [specific capability], based on a comparison of [named alternatives] as of [date]; we will update this claim if alternatives emerge.
- Rated [criterion] in [category] by [named source] among [comparison set] on [date]; results may differ under other test conditions or against products not in this comparison.
- Offers [specific feature] not available in [named comparison set] as of [date]; feature landscape may change.
- Registered with [regulator name] as of [date] in [jurisdiction]; one of the earliest registered advisers using AI-assisted analysis at that date.
Frequently asked questions
- Does a "first AI" claim require a third-party comparison?
- No rule requires a third-party comparison by default, but a buyer who wants to rely on a first claim needs to understand the market scope, comparison set, and date that support it. The SEC Global Predictions case shows that a first-regulated claim without those bounds can be materially misleading. Ask the vendor to name what was compared, when, and in which market.
- Is "industry-leading" treated the same as "best"?
- Both are superlative framing and carry the same evidence burden: comparison set, criteria, and date. The ASA/CAP November 2024 report found that superlative and AI-descriptor combinations in advertising often lack the substantiation needed to support the implied ranking. The buyer question is the same: what was compared, against which criteria, and when?
- Can a "best" claim be supported without a formal study?
- A formal study is not required, but the comparison must be honest and have a defined basis. The same enforcement pattern appears in the SEC and FTC sources on this page: both agencies found that superiority claims — whether financial advisor standing or legal-service capability — require comparison evidence to exist before the claim is published. A vendor who says their product is the best does not need a peer-reviewed study, but they do need a defined comparison set, defined criteria, and a date.
