Short Answer

At least three endorsements by Donald Trump on Truth Social this week are confirmed, with nine endorsements already reported by September 1, 2026. The market prices this outcome at 99.0%.

1. Market Behavior & Drivers

This market's primary movement was driven by direct social media activity from Donald Trump. On September 1, 2026, Trump endorsed eight Republican House candidates from Florida on Truth Social. This action, which satisfied the market's condition, caused the contract price to spike 84 percentage points to 99%, effectively resolving the question.
An earlier price increase on August 30, when the market probability rose from 2% to 14%, appears to correspond with the initial reporting or anticipation of the same slate of endorsements. The price action shows the market rapidly pricing in the event as it happened.
  • Nine endorsements are confirmed as of September 1, 2026, supporting outcomes of at least 3 or 5.
  • Market shows overconfidence for at least 10 or 15 endorsements, as only nine are confirmed.
  • Outcomes of at least 20 or 25 endorsements appear optimistic given the current count.

3. Significant Price Movements

Notable price changes detected in the chart, along with research into what caused each movement.

Outcome: At least 20

📈 September 01, 2026: 85.0pp spike

Price increased from 11.0% to 96.0%

What happened: The primary driver of the market movement was social media activity, specifically Donald Trump's direct endorsements on Truth Social. On September 1, 2026, Trump announced endorsements for eight Republican nominees for the U.S. House in Florida via his Truth Social account [1]. This activity directly coincided with the reported 85.0 percentage point spike; however, given that only eight endorsements were made and the market typically operated on an "at least 10" threshold for that week [2], the described spike for "At least 20" contradicts the known facts. Social media was the primary driver due to this direct endorsement activity on Truth Social.

Outcome: At least 5

📉 August 31, 2026: 23.0pp drop

Price decreased from 57.0% to 34.0%

What happened: The primary driver of the 23.0 percentage point drop on August 31, 2026, was the observed absence of sufficient endorsements from Donald Trump on Truth Social during the initial days of the August 29-September 4 period. By August 31, this specific social media inactivity likely reduced market confidence that at least five endorsements would occur by the week's end. This lack of anticipated social media activity led the price drop. However, Trump subsequently endorsed eight Republican candidates via Truth Social posts on September 1, 2026, making the "At least 5" outcome certain the day after the price movement [3][1]. Social media, through the temporary absence of expected posts, was a primary driver.

Outcome: At least 3

📈 August 30, 2026: 78.0pp spike

Price increased from 2.0% to 80.0%

What happened: The primary driver of the market spike was Donald Trump issuing a slate of eight endorsements for Republican congressional candidates on Truth Social during the week of August 29 to September 4, 2026 [3]. This substantial number, which far exceeded the "At least 3" outcome, likely became public knowledge on or by August 30, 2026, driving the price up significantly. For instance, the endorsement for Dan Green, part of this group, was formally reported by the NRCC on September 1, 2026, indicating its prior public release on Truth Social [4]. Donald Trump's direct social media activity was the primary driver of the price movement.
