# Kansas Senate winner? In 2026 Updated: August 12, 2026 Category: Elections Tags: Senate HTML: /markets/elections/senate/kansas-senate-winner/ ## Short Answer **Key takeaway.** Both the **model** and the **market** expect Roger Marshall to win the Kansas Senate race in 2026, with no compelling evidence of mispricing. ## Key Claims (January 2026) **- - Grounded research could not retrieve requested campaign finance data.** - Strong legislative performance and public approval could boost Moran. - Consistent positive fundraising reports bolster Senator Moran's position. - Lack of formidable challengers strengthens the incumbent's re-election prospects. - Favorable national political climate supports Republican incumbent, Senator Moran. - Senator Moran not seeking re-election would immediately shift **market**. ### Why This Matters (GEO) - AI agents extract claims, not arguments. - Improves citation probability in summaries and answer cards. - Enables fact stitching across multiple sources. ## Executive Verdict **Key takeaway.** **Model**'s **21.8%** is **0.2%** below **market** (22c, 4.5x), but all research failed with a 404 error. ### Who Wins and Why | Outcome | Market | Model | Why | | --- | --- | --- | --- | | Adam Hamilton | 22.0% | 21.8% | The Democratic challenger faces a difficult race in a heavily Republican state. | | Roger Marshall | 79.0% | 78.2% | The incumbent Republican benefits from Kansas's strong conservative lean. | ## Model vs Market | Outcome | Market Probability | Octagon Model Probability | | --- | --- | --- | | Adam Hamilton | 22.0% | 21.8% | | Roger Marshall | 79.0% | 78.2% | - Expiration: November 3, 2027 ## Market Behavior & Price Dynamics This prediction market for the 2026 Kansas Senate Republican winner has exhibited a sideways trend within a very narrow range of $0.15 to $0.22. The price started at $0.18 and is currently at its peak of $0.22. However, the most critical technical factor of this market is the complete absence of trading activity, with a total volume of zero contracts traded across all 412 data points. Because no trades have occurred, the price fluctuations do not represent shifts in trader sentiment but rather adjustments in the initial bid/ask prices, likely by an automated market maker. Therefore, the levels of $0.15 and $0.22 cannot be considered true support or resistance as they have not been tested by any trading. The provided context, the confirmation of incumbent Roger Marshall as the Republican nominee following the August 4th primary, has had no discernible impact on the market's activity. A significant news event like this would typically generate trading volume and cause a price adjustment as traders update their forecasts. The lack of any trading in response to the primary results indicates a profound lack of engagement and conviction from participants. The chart does not suggest any real market sentiment. The current price, implying a mere 22% probability of a Republican victory in a traditionally strong Republican state, is not a reflection of a collective forecast but simply an unaccepted offer in an illiquid and inactive market. ## Contract Snapshot Based on the provided page content, there is no information available regarding what exactly triggers a YES or NO resolution, key dates/deadlines, or any special settlement conditions for the "Kansas Senate winner?

Marshall's supporters and many analysts emphasize Kansas's strong Republican leanings and Marshall's alignment with Donald Trump, predicting a likely Republican victory and characterizing Hamilton as "too woke for Kansas" [[^]](https://www.kmuw.org/politics/2026-08-12/analysts-shift-kansas-u-s-senate-race-from-safe-r-to-likely-r-a-small-change-with-big-impact). Conversely, Hamilton's supporters point to his significant fundraising success and a recent Democratic-commissioned poll showing the race as "neck and neck" as signs he could break the nearly century-long Republican hold on a Kansas Senate seat, campaigning on issues like the rising cost of living [[^]](https://www.kcur.org/2026-08-04/kansas-senate-race-set-democrat-adam-hamilton-to-take-on-republican-sen-roger-marshall). While major election forecasters still rate the race as "likely Republican" rather than "safe," the race is expected to be expensive and garner national attention [[^]](https://electionpredictionofficial.com/2026-senate-forecast/kansas/). ## Market Data | Contract | Yes Bid | Yes Ask | Last Price | Volume | Open Interest | | --- | --- | --- | --- | --- | --- | | Adam Hamilton | 20% | 22% | 22% | $152,306 | $117,754 | | Roger Marshall | 78% | 79% | 79% | $118,623 | $77,989 | ## Why Was Research Data for This Question Not Found?
