The fourth quarter is the most important period on the US vape retail calendar. Between Black Friday doorbusters, Cyber Monday flash sales, and holiday gift shopping, Q4 routinely generates 28–32% of annual vape retail revenue — despite being the shortest quarter by selling days. For 2026, this seasonal peak arrives against a backdrop of accelerating regulatory change, supply chain realignment, and a market that's actively splitting into compliant and unauthorized tracks.

This report provides a comprehensive Q4 2026 holiday season outlook, drawing on Circana retail tracking data, FDA enforcement records, CBP seizure statistics, state revenue data, and industry analyst projections. We examine spending patterns, category shifts, brand positioning, regulatory headwinds, and what both consumers and industry stakeholders should expect in the critical October–December window.
