Marketing Rule Readiness: Substantiation and Evidence
The SEC Marketing Rule, Rule 206(4)-1 under the Investment Advisers Act, governs how registered investment advisers advertise. It replaced the older advertising and cash solicitation rules with a single, principles-based framework covering everything from testimonials and endorsements to performance presentations, and it applies to a broad range of communications aimed at prospective and current clients.
For compliance officers, the rule's central discipline is simple to state and hard to sustain: a firm must be able to substantiate the claims it makes and keep records proving what it said and when. As advisers turn to AI to generate marketing copy at scale, that substantiation burden grows. This page explains the rule and how to keep your advertising continuously evidenced.

What the rule requires
The rule prohibits false or misleading advertising and requires advisers to have a reasonable basis for believing they can substantiate material statements of fact. It sets specific conditions for testimonials and endorsements, including required disclosures about whether the person is a client and whether compensation was paid, and it imposes detailed requirements on how performance may be presented.
Performance advertising carries some of the most exacting conditions, including presentation standards designed to prevent cherry-picking and misleading time periods. Underpinning all of it is a recordkeeping obligation: advisers must retain copies of their advertisements and the records supporting the claims and performance figures they contain.
- No false or misleading statements in advertisements
- A reasonable basis to substantiate material factual claims
- Specific disclosure conditions for testimonials and endorsements
- Detailed presentation standards for performance advertising
- Retention of advertisements and the records that support their claims
Where firms fall short
The most common weakness is claims without a documented basis. Marketing describes results, capabilities, or comparisons that sound reasonable but were never tied to evidence the firm can produce, so when an examiner asks for substantiation there is nothing to show.
AI-generated marketing content sharpens this risk. When copy is produced by an AI tool, it can introduce claims, statistics, or performance framing that no one substantiated and that may not even be accurate. Without a review and substantiation workflow and a record of what was published, firms lose track of what they actually claimed and why.
- Marketing claims with no retained substantiation
- AI-generated copy introducing unverified claims or figures
- Testimonials and endorsements missing required disclosures
- Performance presentations that cannot be reproduced from underlying records
- No reliable archive of what was published and when

FAQ
Frequently Asked Questions
What counts as an advertisement under the Marketing Rule?+
The rule defines advertisement broadly to capture most communications an adviser uses to offer its services to prospective clients or investors, as well as certain compensated endorsements. Because the definition is broad, firms should assume a wide range of marketing communications is in scope.
What does substantiation mean here?+
Advisers must have a reasonable basis for believing they can substantiate material statements of fact in an advertisement. In practice that means keeping the supporting evidence for claims so it can be produced if the SEC requests it.
Are testimonials and endorsements allowed?+
Yes, subject to conditions. The rule permits them only with required disclosures, including whether the person giving it is a client and whether compensation was provided, along with oversight and other conditions set out in the rule.
How does the rule apply to AI-generated marketing content?+
The rule applies to the content regardless of how it was created. AI-generated copy raises heightened governance and substantiation questions because it can introduce claims no one verified, so firms should review and substantiate it and keep records just as they would for any advertisement.
