Description

This event tracks the frequency of Donald Trump's posts on his Truth Social platform over a specific week. It provides a structured way to assess his activity level during that period, helping to gauge his engagement and communication patterns through a quantifiable metric.

Kalshi

The event resolves based on the total number of Truth Social posts made by Donald Trump between September 20, 2026, at 12:00 AM ET and September 26, 2026, at 11:59 PM ET. Each market corresponds to a specific post count range, with various tiers from below 80 posts up to more than 240 posts. All post types—including Truths, ReTruths, Quote Truths, and Replies—are counted if captured by the primary source, Roll Call. The count is determined at 10:00 AM ET on September 27, 2026. Deleted posts as of the expiration time are excluded from all counts. If Roll Call data is unavailable or inaccurate, alternative sources may be used at Kalshi's discretion. The "Between" ranges are inclusive of both the lower and upper bounds for each market.
