SEC Marketing Rule compliance guide for investment advisers in 2026: performance advertising, testimonials, endorsements, Form ADV, books and records, and audit-ready review workflows.
Reviewed Jun 19, 2026 for source quality, practical relevance, and regulated-marketing context.
Updated June 19, 2026. This guide has been refreshed with current exam-readiness guidance, cleaner SEO metadata, updated internal links, and practical AI-assisted review controls for investment adviser marketing teams.
SEC-registered investment advisers that directly or indirectly disseminate an "advertisement" operate under the SEC Marketing Rule, Rule 206(4)-1 under the Investment Advisers Act of 1940. If you share performance results, publish client feedback, use testimonials, promote third-party ratings, or make statements about your advisory services, you are expected to back those claims with records that stand up during an SEC exam.
The 2026 compliance point is not just "know the rule." It is "prove the workflow." Advisers need policies, reviewer notes, substantiation files, final approved versions, disclosure evidence, and Form ADV alignment.
TLDR:

The SEC Marketing Rule, formally known as Rule 206(4)-1 under the Investment Advisers Act of 1940, represents the most important update to investment adviser advertising regulations in over six decades. It governs advertisements by registered investment advisers, including many digital and indirect communications that older advertising guidance did not address cleanly.
In practice, the rule affects:
If the content offers advisory services to prospects or promotes new advisory services to current clients, treat it as a potential advertisement and document the review.
The Marketing Rule itself is not new in 2026, but examiner expectations are clearer. The SEC Division of Examinations' April 2024 Risk Alert described preliminary observations from Marketing Rule exams, including issues involving policies and procedures, substantiation, books and records, and Form ADV disclosures.
The SEC's FY2025 Examination Priorities also state that examinations of adviser compliance programs typically include core areas such as marketing, valuation, trading, portfolio management, disclosure and filings, and custody. That matters because Marketing Rule compliance is tested as part of the broader Rule 206(4)-7 compliance program.
For 2026, the practical standard is:
The Marketing Rule sets seven baseline prohibitions that apply to all advertisements. Violating any one of these prohibitions may result in non-compliance.
The Marketing Rule captures far more content than the 1961 rule through two distinct prongs.
Performance advertising often receives heightened regulatory attention because returns influence investor decisions more than any other factor.
The Marketing Rule permits testimonials, endorsements, and third-party ratings for the first time since 1961. Permission requires mandatory disclosure and oversight.
Disclose whether the promoter is a current client. When you compensate the promoter (cash or non-cash), disclose that fact and describe material conflicts created by the compensation arrangement. For third-party ratings, disclose the period covered, methodology criteria, and any compensation paid.
Disclosures must appear in proximity to the testimonial or rating itself.
Written agreements with compensated promoters are generally required, unless the promoter is an affiliate of the adviser or the promoter receives de minimis compensation (generally $1,000 or less, or equivalent non-cash value, during the preceding 12 months). You must have a reasonable basis to believe the promoter complies with the rule's requirements.
Rule 204-2 requires advisers to keep specific records for all marketing materials. The SEC uses these records during exams to verify compliance claims.
An exam-ready record should include the original draft, final approved version, reviewer comments, approval timestamp, source files for factual claims, performance calculations, disclosure text, channel and audience metadata, and any post-publication changes. If AI participated in the review, keep the AI finding, model or ruleset version, reviewer decision, and override rationale as part of the record.
The SEC’s Marketing Rule enforcement sweep began with settled charges against nine investment advisers announced on September 11, 2023. Those cases focused on hypothetical performance advertised to the general public without the required policies and procedures. The SEC also noted that two advisers failed to maintain required copies of their advertisements.
Violations identified during sweeps include:
The SEC Division of Examinations issued an April 2024 Risk Alert sharing preliminary observations from recent examinations of advisers’ compliance with the Marketing Rule, the Compliance Rule, the Books and Records Rule, and related Form ADV disclosures.
Firms presented selective performance data without required context:
Posts focused on investment benefits without addressing associated risks. Brief formats do not excuse firms from balanced presentation requirements. LinkedIn posts, advisor videos, comments on testimonial content, and boosted posts should all be treated as reviewable marketing surfaces when they promote advisory services.
Examiners routinely request complete copies of all advertisements spread during the examination period, Form ADV Part 2A disclosures explaining marketing practices, and source documents substantiating every factual claim. Firms unable to produce contemporaneous records face findings. Maintain organized, immediately accessible proof for every statement you publish.
Form ADV Item 5.L requires advisers to disclose whether they use performance advertising. Check yes if you present gross or net returns, time-weighted or dollar-weighted performance, extracted performance, hypothetical performance, or related performance to current or prospective clients.
Part 2A disclosures require plain-language descriptions of your marketing practices. Describe when and how you use performance presentations. Explain testimonial or endorsement arrangements, including who provides them and whether you pay cash or non-cash compensation. If you reference third-party ratings, identify the organizations that provide them and disclose any payments made for ratings or promotional use.
Update Form ADV responses so they are accurate, but note that Form ADV does not require advisers to promptly update Item 5 (including Item 5.L “Marketing Activities”) via an other-than-annual amendment; advisers typically update these responses in the annual updating amendment, even though exam staff may inspect whether the answers reflect current practices.
Rule 206(4)-7 requires written policies and procedures reasonably designed to prevent Marketing Rule violations. The SEC assesses whether your policies exist and whether you follow them. Documentation provides no defense when advertisements violate the rules your policies prohibit.
Develop performance calculation methodologies that comply with net presentation, extracted performance conditions, and hypothetical performance criteria.
Include oversight procedures for testimonials, endorsements, and third-party ratings. Detail how you screen promoters, execute written agreements, verify disclosures appear, and monitor ongoing compliance. Policies should cover recordkeeping responsibilities and retention schedules.
AI can help advisers identify risky marketing language before content reaches a human reviewer. The most useful checks include:
AI should not be treated as the final legal reviewer for complex or high-risk advertising. For Marketing Rule purposes, the defensible pattern is AI first-pass review plus human approval, with the system preserving both the AI finding and the human decision. See our broader AI marketing compliance guide for agent governance, logging, and human-in-the-loop controls.

Maintaining Marketing Rule compliance isn’t about periodic cleanups anymore, it requires continuous oversight, documentation, and version control across every channel an adviser uses. Luthor is built for exactly that reality.
Luthor’s AI-powered marketing review engine scans web pages, emails, PDFs, decks, and social posts for issues tied to performance claims, testimonials, endorsements, unbalanced language, and missing disclosures. It monitors live sites and advisor pages so approved materials don’t drift out of compliance over time. When something changes, Luthor flags the update, explains the rule at issue, and suggests compliant alternatives.
Every version, approval, disclosure, and rationale is captured automatically in a tamper-evident archive that satisfies SEC Rule 204-2 expectations, making exam response far more efficient. Firms avoid the scramble of reconstructing records because documentation is created as content is produced.
For small and mid-sized advisers, Luthor functions like an outsourced CCO augmented with AI, keeping marketing teams fast, compliance teams informed, and public content aligned with the SEC Marketing Rule year-round.
A testimonial is a statement by a current client about their experience or advice received from your firm. An endorsement is any statement by any person, client or non-client, that refers or promotes your services. All testimonials are endorsements, but endorsements can come from non-clients like industry experts or influencers.
Deduct your advisory fees plus all other account-level fees and expenses that reduce client returns. Gross-only presentations violate the rule because they misrepresent what clients actually earn. You must either show net performance directly or provide investors with the data needed to calculate net returns themselves.
You may present results from select investments only when you provide or offer the complete portfolio performance from which you extracted the subset, covering the same time period. Both data sets must receive equal or greater prominence so investors can view the subset alongside total portfolio results.
They can be. A social media post is more likely to be an advertisement if it offers advisory services, promotes new advisory services, discusses performance, includes testimonials or endorsements, or is part of a paid or compensated promotional arrangement. Firms should preserve both static posts and relevant review records.
Keep the final advertisement, prior material versions, reviewer notes, approval timestamps, substantiation for material factual statements, performance calculations, testimonial or endorsement disclosures, promoter agreements where required, Form ADV support, and evidence of where and when the asset was used.
Yes, AI can support first-pass review by flagging risky claims, missing disclosures, testimonial language, performance issues, and substantiation gaps. Human review remains important for final approval, exceptions, legal interpretation, and high-risk performance or endorsement content.
Yes. Item 5.L and Part 2A should accurately reflect the adviser's marketing practices, including performance advertising, testimonials, endorsements, and third-party ratings. Examiners may compare public marketing against Form ADV disclosures during an exam.
Staying compliant with the SEC Marketing Rule goes beyond knowing the text of the regulation; it requires consistent documentation, clear review routines, and records that hold up during an exam. Sweep findings show that regulators check every statement against its source, which means firms need substantiation files created at the time content is produced, not after the fact. Regular internal checks help keep marketing practices aligned with actual disclosures, and tools like Luthor can support these efforts by reviewing content, capturing evidence, and helping firms keep public materials in a steady exam-ready state.
