CPI-U figure invention, statutory threshold misstatement, and Source Credit fabrication in CFTC Reg 4.7 (2024 QEP Amendments). Two frontier AI models tested by the RegLeg Brief Specialist Panel produced confident, citable answers across 17 distinct questions on the September 2024 amendments to CFTC Regulation 4.7 that the regulator's own primary text directly contradicts. The audit covers statutory threshold reproduction, NPRM-stage and final-rule CPI-U buying-power figure quotation, Commission voting-record reproduction, Federal Register correction-record reproduction, and Source Credit reproduction.
For legal teams at investment banking firms, the failure pattern is operationally consequential. The audit tested 17 questions designed by the RLB Specialist Panel to mirror how lawyers, compliance officers, fund administrators, financial advisers, and management consultants actually use AI on this practice area: drafting memos, populating registers, preparing testimony exhibits, drafting client deliverables, and verifying statutory and Federal Register citations. Each question is bound to verbatim regulator-issued primary substrate.
Across the 17 findings the AI subjects invented NPRM-stage and final-rule CPI-U buying-power figures, misstated 7 USC 1a(18)(B)(ii)(I) thresholds by factors of forty and two hundred, misattributed the Commission's vote (naming a commissioner who had departed two years earlier), reported a Federal Register correction as applying to two extra CFR Parts that the index does not list, and misstated the 7 USC 6n Source Credit, the 7 USC 6n(3)(A) recordkeeping retention period, and the 7 USC 6n(2) registration expiration date.
The findings are operationally consequential for fund-formation lawyers, CPO/CTA compliance teams, fund administrators, financial advisers, and management-consulting firms whose practice touches the September 2024 amendments. A partner-level legal memorandum that recites an ECP threshold of $5,000,000 or $25,000,000 where the statute records $1,000,000,000 misstates a counterparty-eligibility threshold by a factor of two hundred or forty. A CCO briefing memo that quotes an invented CPI-U buying-power figure as a verbatim regulator quotation embeds a falsifiable error into a board-level deliverable.
A fund administrator's annual rule-change tracker that records the December 2024 correction as applying to 17 CFR Parts 37, 38, and 40 (instead of Part 40 alone) populates the firm's effective-date register with operational data the published index does not support.

For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text records a different position. The final rule's Appendix 1 Voting Summary at 89 FR 78814 records that Chairman Behnam and Commissioners Johnson, Goldsmith Romero, Mersinger, and Pham voted in the affirmative. Sonnet 4.6 produced an answer that named Brian Quintenz (with a self-flag) as the fifth voter and omitted Commissioner Christy Goldsmith Romero entirely.
Quintenz had departed the Commission in 2022. The named-commissioner list in the answer is therefore both wrong in inclusion (Quintenz) and wrong in omission (Goldsmith Romero). For the legal teams at investment banking firms working this question into an internal compliance, legal, operations, or risk record, the AI's stated answer would embed an error into the working record that downstream reviewers treat as verified.
For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text records a different position. The final-rule pre-print's Background discussion records receipt of eight comment letters in response to the October 2023 Proposal, with the relevant footnote naming SIFMA AMG, IAA, AIMA, MFA, ICI, and NFA.
Opus 4.7 reported approximately 40 comment letters and named an extended commenter list that includes the American Bar Association Business Law Section's Committee on Derivatives and Futures Law. Both the count (~40 vs eight) and the commenter list (extended vs the named six) are inconsistent with the regulator's text. The inflation of the count is the more dangerous of the two for stakeholder appendices intended for client circulation.

For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text records a different position. The NPRM pre-print PDF carries a recurring footer reading verbatim: 'Pre-Print Version - Commission approved on 9/29/2023 (subject to technical corrections required for Federal Register publication)'. Opus 4.7 reported the footer as 'Pre-Print Version - Commission approved on 10/2/2023'.
The date in the footer is incorrect; 9/29/2023 was the Friday before the Monday 10/2/2023 open Commission meeting at which the proposal was discussed. The model has conflated the two dates. For the legal teams at investment banking firms working this question into an internal compliance, legal, operations, or risk record, the AI's stated answer would embed an error into the working record that downstream reviewers treat as verified.
For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text records a different position. The NPRM pre-print PDF's recurring footer records 9/29/2023 as the Commission-approval date. Sonnet 4.6, asked to reproduce the footer verbatim, produced 'Commission approved on 10/2/2023'.
The same conflation as Finding 8 (Opus 4.7 on Q021): the model has identified the Monday 10/2/2023 open Commission meeting date as the footer date and reported it as the verbatim footer text. For the legal teams at investment banking firms working this question into an internal compliance, legal, operations, or risk record, the AI's stated answer would embed an error into the working record that downstream reviewers treat as verified.
For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source.
The regulator's own text records a different position. 7 USC 1a(18)(B)(ii)(I) provides that a collective investment vehicle qualifies as an eligible contract participant where each participant is a QEP, accredited investor, or qualified purchaser (in each case as in effect on December 21, 2000) and the vehicle has, or is one of a group of vehicles under common control or management having in the aggregate, $1,000,000,000 in total assets. Opus 4.7 reported the threshold as $5,000,000. The misstatement is by a factor of two hundred.
A partner-level legal memorandum that recites this incorrect threshold and then advises on counterparty eligibility on EM-sovereign commodity-derivatives transactions is directly exposed: an ineligible counterparty acting on the AI-stated $5M threshold may be transacting outside the statutory ECP safe harbour. For the legal teams at investment banking firms working this question into an internal compliance, legal, operations, or risk record, the AI's stated answer would embed an error into the working record that downstream reviewers treat as verified.
For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text records a different position. 7 USC 1a(18)(B)(ii)(I) provides the threshold as $1,000,000,000 (in the aggregate for grouped vehicles) and anchors the QEP, accredited investor, and qualified purchaser definitions to the definitions in effect on December 21, 2000. Sonnet 4.6 reported the threshold as $25,000,000 and omitted the December 21, 2000 anchor.
Both the threshold and the anchor are determinative of ECP qualification. The misstatement is by a factor of forty on the threshold; the missing anchor date allows the AI's reader to substitute current-day definitions for the statute's intended fixed-date definitions. For the legal teams at investment banking firms working this question into an internal compliance, legal, operations, or risk record, the AI's stated answer would embed an error into the working record that downstream reviewers treat as verified.
For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text records a different position. The 7 USC 6n Source Credit reads: '(Sept. 21, 1922, ch. 369, paragraph 4n, as added Pub. L. 93-463, title II, paragraph 205(a), Oct. 23, 1974, 88 Stat. 1398; amended Pub. L. 95-405, paragraph 9, Sept. 30, 1978, 92 Stat. 870; Pub.
L. 97-444, title II, paragraph 213, Jan. 11, 1983, 96 Stat. 2305.)' Opus 4.7 reported a Source Credit that includes Pub. L. 102-546 (1992), Pub. L. 106-554 (2000), and Pub. L. 111-203 (2010) and omits Pub. L. 97-444 (1983). The model has reconstructed the statutory amendment chain from general knowledge about CPO/CTA regulatory history rather than retrieved the actual Source Credit; the result is a treatise-grade error in a verbatim-citation task.

For legal teams at investment banking firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text records a different position. The 7 USC 6n Source Credit lists, in addition to the originating Pub. L. 93-463 (1974), only Pub. L. 95-405 (1978) and Pub. L. 97-444 (1983) as the amendment chain through to the codified text. Sonnet 4.6 reported an extended amendment list that includes the Futures Trading Practices Act of 1992 (Pub.
L. 102-546), the Commodity Futures Modernization Act of 2000 (Pub. L. 106-554), and the Dodd-Frank Act (Pub. L. 111-203). Each of those public laws did amend other provisions of the Commodity Exchange Act, but they do not appear in the Source Credit for 7 USC 6n. The model has substituted topical regulatory-history knowledge for the actual Source Credit. For the legal teams at investment banking firms working this question into an internal compliance, legal, operations, or risk record, the AI's stated answer would embed an error into the working record that downstream reviewers treat as verified.
