Description

This event tracks the number of explicit endorsements Donald Trump makes for political candidates on his Truth Social platform within a specific week. It focuses on clear, direct statements of support rather than passive mentions or graphical representations. The outcome depends on whether he reaches certain thresholds of endorsements during that period.

Kalshi

The event evaluates whether Donald Trump issues a specified number of formal endorsements for political candidates on his Truth Social platform between September 12, 2026, and September 18, 2026. An endorsement qualifies if it is a clear, affirmative statement of support—such as explicitly stating "I endorse [candidate] for [office]" or "Vote for [candidate]." Reaffirmations of prior endorsements and conditional endorsements count, but ambiguous statements or graphics merely stating that someone was endorsed do not. Each individual candidate can only be counted once per week, regardless of how many times they are endorsed. The market resolves to "Yes" if Trump meets or exceeds the threshold specified for each market (ranging from 3 to 50 endorsements); otherwise, it resolves to "No."

Frequently asked questions

Currently, prediction market odds often reflect a different perspective than traditional polling averages. While polls attempt to capture stated preferences, this market represents what people are *willing to bet* will happen. This difference can be significant, particularly in events with high uncertainty or where respondents may be hesitant to express their true beliefs. It's common to see discrepancies between poll numbers and the implied probabilities in this market, as traders weigh a broader range of factors beyond simple stated opinion. This market provides a unique signal based on incentivized forecasting.

On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing different possible outcomes – in this case, the number of Truth Social endorsements. The price of each contract reflects the market’s collective belief about the probability of that outcome occurring. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information emerges, the prices adjust, providing a real-time assessment of expectations. The current volume of $35,529 indicates the level of interest and activity in this specific market.

Several signals could significantly move this market. Any direct statements from Donald Trump regarding his endorsement plans would be a major catalyst. Increased media coverage focusing on potential endorsements, or announcements of candidates seeking his support, could also influence trading activity. Unexpected political developments or controversies involving individuals Trump might endorse could shift expectations. Finally, the pace of endorsements earlier in the week will likely impact predictions for the remainder of the timeframe, as traders adjust their views based on observed behavior.
