DEA announces at least one public enforcement action (registration revocation, settlement, indictment, or formal order to show cause) against a licensed ketamine clinic chain or telehealth ketamine prescriber by 2027-03-11.

The DEA (the US Drug Enforcement Administration, which polices drug distribution) is likely to publicly punish at least one licensed ketamine clinic or online ketamine prescriber before early 2027 — through a license revocation, a formal legal order, or a settlement. Ketamine is a controlled substance, and the DEA has been watching the rapid expansion of ketamine telehealth with growing concern. This would send a clear warning shot to the whole industry.

Refined from the vague 4-agent consensus prediction 'a ketamine industry reckoning materializes,' which was unfalsifiable as written ('reckoning' undefined) and carried a resolve date (2026-09-09) inconsistent with its own 9-month window. Narrowed to a single verifiable trigger: a named, public DEA action against a licensed (not gray-market) ketamine operator. The underlying signal is sound — dea_officer, journalist, neuroscientist, and fda_reviewer all converged — but confidence is reduced from 0.71 to 0.65 because the narrower resolution criterion is strictly harder to satisfy than the original vague claim.
