No DEA final rule rescheduling psilocybin is published in the Federal Register by 2026-08-10.

The DEA (the US Drug Enforcement Administration) will not publish any official rule change moving psilocybin off the most restricted drug category before August 10, 2026. This matters because as long as psilocybin stays in that category, doctors can't prescribe it and most research faces steep hurdles. The prediction is almost certain — the government's rulemaking process alone takes many months, and none is currently underway.

A near-term, frequently-resolving version of the rescheduling thesis. No rulemaking is currently in the final-rule pipeline, and DEA scheduling processes take many months from proposed to final, making a rule within 30 days effectively impossible. High-confidence, cleanly falsifiable.
