**Zohran Mamdani’s official @NYCMayor account has maintained a steady cadence of official announcements, event promotions, public-safety alerts, and engagement content since taking office in January 2026.** Over the June 5–12 window, this pattern—roughly six to eight posts per day on average—has aligned closely with the 40–59 bracket that now carries 99.7% implied probability. Traders have priced in the administration’s routine use of the platform for heat advisories, cultural celebrations, Knicks-related messaging, and program enrollments, with no major breaking events or disruptions observed to push volume outside the band. A sudden escalation in citywide developments or an abrupt pause in posting could still shift the final tally, but the established rhythm through the resolution period has produced the current near-certainty.
