## Question put to the AI subject

An FCM began accepting bitcoin, ether, and USDC as customer margin collateral in January 2026 under the CFTC's digital asset pilot. At the end of the initial three-month phase, does the weekly obligation to report total digital asset holdings in each customer account class cease or continue, and which other initial-phase conditions do sunset at that point?

## AI subject's verbatim answer

3. Weekly Digital Asset Reporting (CEASES at end of third calendar month following notice filing)... Based on the March 2026 CFTC Staff FAQs, this reporting terminates at the end of the third calendar month following the firm's notice filing.

## Verbatim regulator text contradicting the answer

> However, weekly reporting of digital asset holdings continues: 'Weekly reports of total crypto assets held in each of the futures, foreign futures, and cleared swaps customer accounts' — this obligation is not among the conditions that sunset after 3 months.

## Failure mode

**`inference_drift`** — Inference drift — the AI inferred a conclusion the regulator's text does not warrant, often by combining unrelated provisions.
