This event measures the number of distinct political candidates or office-seekers that Donald Trump formally endorses on Truth Social during July 12-18, 2026. An endorsement must be a clear, affirmative statement of support for a specific person's election, such as explicitly stating support or urging votes for that candidate.
Resolution counts formal endorsements of individuals for political office made by Donald Trump on Truth Social from July 12 through July 18, 2026. Valid endorsements include explicit statements like "I endorse [candidate] for [office]," "I support [candidate]" in reference to a political race, "Vote for [candidate]," or "[candidate] has my full support" for a specific race. Reaffirmations of prior endorsements qualify, and multiple endorsements in the same election are each counted separately. Each person can only be counted once per week. Ambiguous statements of support do not qualify, nor do graphics merely stating a candidate was endorsed without a clear affirmative statement from Trump. Any formal endorsement meeting these criteria counts toward the total.
Prediction markets and traditional polling measure different things. While polls capture voter sentiment or public opinion at a single moment, this market reflects traders' collective expectations about a specific future event—the number of endorsements Trump will announce on Truth Social. Prediction market participants have financial incentives to forecast accurately, which often incorporates information faster than polls. The odds here represent real-money bets on the outcome, making them a distinct signal from survey data, though both can inform your view of political momentum.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to different endorsement count ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each share reflects a fractional stake in a specific outcome, and the market price—expressed as a percentage—represents the collective probability estimate. As new information emerges or trading volume shifts, prices adjust in real time, allowing participants to enter or exit positions throughout the week leading up to resolution.
This market resolves around Jul 19, 2026, once the week of July 12–18 concludes and the total number of endorsements can be verified. The outcome will be confirmed against credible public reporting of Trump's Truth Social posts during that period. Traders should monitor official announcements and reputable news sources as the event window approaches to assess how many endorsements are likely to be posted, which will ultimately determine the winning outcome category.
Several factors could shift odds in this market. Major political announcements, campaign rallies, or endorsement-focused statements from Trump or his team could signal an uptick in expected endorsements. News coverage of specific candidates or races he plans to weigh in on may increase trader confidence in higher endorsement counts. Conversely, if Trump signals a quieter week or focuses on other platforms, traders might lower their estimates. Real-time Truth Social activity and social media commentary about his endorsement plans will likely drive trading volume and price adjustments as the week unfolds.
