Will Mamdani sign an executive order?

Currently, it's difficult to directly compare this market to traditional polling averages, as there are no readily available polls specifically addressing whether Mamdani will sign an executive order this week. However, prediction markets often incorporate information beyond what polls capture, such as insider knowledge and nuanced interpretations of events. This can lead to differences between prediction market probabilities and polling data. If polls become available, it will be interesting to see how they align with the collective wisdom expressed in this market.

On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing the likelihood of the event occurring. The price of a contract reflects the market's consensus probability. As more traders participate, the price converges towards what the market believes is the true probability. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The current price indicates what traders are willing to pay to own a contract that pays out if Mamdani signs the executive order, and what they are willing to accept to sell one. This dynamic pricing mechanism allows for efficient information aggregation.

This market resolves around Dec 18, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution will depend on whether a publicly released executive order signed by Mamdani is dated between September 13th and September 19th, 2026. The market will determine whether an executive order was signed during the specified week, based on official documentation and widely available news sources. The outcome will be based on objective evidence, not subjective interpretation.

Several signals could significantly impact this market. Any official statements from Mamdani or his administration regarding potential executive actions would be a key driver. Unexpected political developments, legislative updates, or relevant court rulings could also shift expectations. Furthermore, major news events or public pressure related to the issues an executive order might address could influence trading activity. Increased volume in this market, particularly leading up to Dec 18, 2026, would also indicate heightened attention and potential price swings.
