Otherwise, this market will resolve to "No." An approval is defined as: For new drugs: FDA issuance of an approval letter for a New Drug Application (NDA) or Biologics License Application (BLA) For already-marketed drugs seeking new indications: FDA approval of a supplemental NDA (sNDA) or supplemental BLA (sBLA) for the specific indication referenced For generic drugs: FDA approval of an Abbreviated New Drug Application (ANDA) For biosimilars: FDA approval of a 351(k) application The following constitute qualifying approvals: Standard approval (traditional approval based on clinical benefit), Accelerated approval (based on surrogate endpoints), Approval with Risk Evaluation and Mitigation Strategy (REMS), Approval with restricted distribution or indication limitations, except compassionate use/expanded access programs The following do not constitute qualifying approvals: Approvable letters that require additional actions before approval Tentative approvals pending patent or exclusivity expiration FDA requests for additional information or studies Extension of Prescription Drug User Fee Amendments dates Approval for compassionate use or expanded access programs only Approval only for export or for use outside the United States Emergency Use Authorization (EUA) without full approval Complete Response Letters (CRLs) indicating the application cannot be approved in its current form This market will immediately resolve to "No" if the FDA issues a Complete Response Letter (CRL) or explicitly declines to approve the application.

Conditional approvals may include post-marketing requirements or commitments and still qualify. The primary resolution source will be official information from the FDA; however, a consensus of credible reporting will also be used.Trader consensus on Polymarket prices "Yes" for FDA approval of Axsome Therapeutics' AXS-05 at 78.8%, driven by the agency's Priority Review grant in January 2026 for the supplemental new drug application targeting agitation in Alzheimer's disease, setting today's April 30 PDUFA target action date. Robust Phase 3 data from the ADVANCE trials—demonstrating a 3.6-fold lower relapse risk versus placebo—bolstered by Breakthrough Therapy designation since 2020 and no advisory committee requirement, signal strong regulatory momentum amid an acute unmet need, with only brexpiprazole currently approved. While one acute-phase trial shortfall and elderly safety scrutiny temper full certainty, the lack of recent red flags has solidified trader optimism ahead of the imminent decision.
