About This Event
in primaries from Apr 10, 2026 to Sept 16, 2026 If the number of Trump-endorsed candidates who lose their respective primary election held after Apr 10, 2026 and before Sept 16, 2026 is exactly X then the market resolves to Yes. Endorsements are determined per the specifications of the ENDORSE contract. An endorsement must be made before the primary to count; if Trump endorses multiple candidates in the same race, that race is excluded. "Primary" includes runoffs and top-two/jungle primaries, e
Current Market Outlook
The market is pricing a 25% chance that exactly 7 Trump-endorsed candidates lose their primaries between April 10 and September 16, 2026. That is a specific number, not a range, which makes this a tight bet. A 25% probability means the market sees this as unlikely but very much in play. If you think the number will be higher or lower, the contracts on either side of 7 are likely offering better value.
Key Factors Driving the Odds
Trump's endorsement record in 2022 was mixed. Of the 230+ candidates he endorsed in the 2022 midterm primaries, about 93% won their primaries. But the losses that did happen were concentrated in high-profile races where Trump picked flawed candidates like Dr. Oz in Pennsylvania or Herschel Walker in Georgia. Those losses came in general elections, not primaries.
In 2024, Trump's endorsement power in primaries remained strong, with only a handful of losses. The 2026 cycle will be different because Trump will be a sitting president, not a former one. Sitting presidents typically see higher endorsement win rates. However, the 2026 map includes open Senate seats in Georgia, North Carolina, and Michigan where Trump may back candidates who face serious primary challenges.
The "exactly 7" number matters because the total number of Trump endorsements in primaries is also unknown. If Trump endorses 50 candidates, 7 losses is a 14% loss rate, which is higher than 2022. If he endorses 100, 7 losses is just 7%, which is below the historical average.
What Could Change These Odds
The biggest unknown is how many primaries Trump actually wades into. If he stays out of most downballot races and only endorses in safe seats, the loss count drops. If he backs challengers to sitting Republicans who voted for impeachment or voted against his agenda, the loss count rises.
The April 10 start date excludes early primaries. Texas, California, and Ohio hold their primaries in March 2026, so those races are out. The window covers most of the spring and summer primaries, including potential runoff elections in states like Georgia and Mississippi.
Watch for Trump endorsements in open primaries against incumbent House members. Those tend to produce the most losses. If Trump endorses 10 or more such challengers, the probability of exactly 7 losses jumps. If he mostly sticks to safe incumbents, the number will be closer to zero.
Cross-Platform Analysis
This market trades only on Kalshi, so there is no cross-platform arbitrage to discuss. The single-platform pricing means the market reflects the collective judgment of Kalshi traders, who tend to be more politically engaged than the general public. The lack of Polymarket competition means the 25% price may be less efficient than it would be with multiple betting pools.

Overview
This prediction market focuses on the number of candidates endorsed by former President Donald Trump who lose their primary elections between April 10, 2026, and September 16, 2026. The market resolves to 'Yes' if exactly X number of Trump-endorsed candidates are defeated in their primaries during that window. Endorsements must be made before the primary date, and if Trump endorses multiple candidates in the same race, that race is excluded. Primaries include runoffs and top-two or jungle primaries, which are common in states like California and Washington. The market is set against the backdrop of the 2026 midterm elections, where Trump's influence within the Republican Party remains a central factor. Since leaving office, Trump has maintained a high-profile role in GOP primaries, endorsing candidates who align with his political agenda and often challenging incumbents he views as disloyal. The outcome of these primaries will signal the strength of his endorsement and the broader direction of the party. Observers are watching closely to see if his endorsement power has waned after some high-profile losses in the 2022 midterms, or if he remains a kingmaker. The market period also covers a specific timeframe that excludes the earliest and latest primaries, focusing on the summer stretch when many states hold their contests. This creates a defined set of races for analysis.
Historical Context
The use of presidential endorsements in primary elections has a long history, but Donald Trump's approach is distinctive. Unlike previous presidents who often stayed neutral in primaries, Trump has aggressively endorsed candidates, particularly those who support his claims of a stolen 2020 election. In the 2022 midterm cycle, Trump endorsed over 200 candidates, with a win rate of about 93% in primaries. However, several high-profile losses occurred, including David Perdue in Georgia's gubernatorial primary, Dr. Mehmet Oz in Pennsylvania's Senate primary, and Herschel Walker in Georgia's Senate general election (though Walker won his primary). These losses were notable because they occurred in key swing states and were seen as tests of Trump's ability to pick winners. The 2022 cycle also saw Trump endorsing against incumbents like Representative Liz Cheney, who lost her primary in Wyoming by 37 points. In 2024, Trump's endorsement record continued, with a similar high win rate but notable exceptions, such as his endorsed candidate for Alabama's Senate seat, Katie Britt, who won easily, but others like Kari Lake in Arizona lost their general elections. The 2026 cycle will be the first midterm since Trump left office with a more established track record. The period from April to September covers the bulk of primary season, including key states like Texas, California, and New York. Past data shows that Trump's endorsement is most effective in safe Republican districts where the party base is dominant, but less so in swing districts where general election appeal matters.
Why It Matters
The number of Trump-endorsed candidates who lose their primaries is a direct measure of his political influence within the Republican Party. If many lose, it could signal that his endorsement power is declining, potentially weakening his position as the party's de facto leader. This could affect his ability to shape policy, recruit candidates, and potentially run for office again. Conversely, if few lose, it reinforces his dominance and could discourage challengers from opposing his preferred candidates. The results also have practical implications for the 2026 general elections. If Trump-endorsed candidates who are seen as extreme or controversial win primaries, they may be less competitive in general elections, potentially costing Republicans seats in Congress. This could affect the balance of power in the House and Senate, with downstream effects on legislation, judicial appointments, and the 2028 presidential race. For investors and political analysts, these primaries offer early indicators of party dynamics and electoral trends. The market provides a way to quantify and trade on these expectations, reflecting collective wisdom about Trump's sway.
Current Status
As of early 2025, the 2026 primary season is still over a year away, but the landscape is already forming. Trump has maintained a strong grip on the party, with most Republican candidates seeking his endorsement. However, some party strategists are urging a more selective approach to avoid backing candidates who might lose general elections. The 2024 general election results, where Trump won the presidency, have reinforced his influence, but also raised expectations. Key races to watch include open seats in states like Ohio, North Carolina, and Florida, where Trump may endorse candidates against establishment figures. The market is trading based on early assessments of how many competitive primaries will occur and how many Trump-backed candidates might face serious challenges. No major endorsements have been made yet for 2026, but Trump's team is likely to start vetting candidates in late 2025.
Frequently Asked Questions
How does Trump's endorsement affect primary election outcomes?
Trump's endorsement typically boosts a candidate's name recognition, fundraising, and support from the party base. Studies show it can increase a candidate's vote share by 5-10 percentage points, especially in low-information races. However, it can also alienate moderate voters and independent voters in general elections.
What determines whether a Trump endorsement is 'official'?
For this market, an endorsement is determined by the ENDORSE contract specifications, which typically require a public statement from Trump or his official campaign account on social media or in a press release. Endorsements made verbally at rallies or through surrogates may also count if documented.
Which states hold primaries during the April 10 to September 16, 2026 period?
This period includes most state primaries, with key dates like California and New York in June, and several states in August and early September. States with primaries before April 10 (like Texas and Illinois) are excluded. A full list is available from state election boards or the Federal Election Commission.
How many Trump-endorsed candidates lost primaries in 2022?
In 2022, about 14 Trump-endorsed candidates lost their primaries, out of over 200 endorsements. This includes losses in high-profile races like David Perdue in Georgia and Dr. Oz in Pennsylvania, though Oz won his primary but lost the general election.
Can Trump endorse multiple candidates in the same race?
If Trump endorses multiple candidates in the same primary race, that race is excluded from the market's count. This prevents ambiguity. Historically, Trump has rarely done this, but it has happened in crowded fields where he initially endorsed one candidate and later switched.
