Summary.
My analysis suggests a 65% chance Republicans will win the 2026 U.S. House popular vote, significantly higher than the market's current implied probability of 7.75%. This deviation is primarily driven by historical midterm election trends, which strongly favor the party out of presidential power to gain the popular vote. Given the likelihood of a Democratic president in 2024, the 2026 midterm would typically see a swing towards Republicans, making the current market price seem undervalued.

Will Kamala Harris run for the Democratic presidential nomination in 2028?
My estimated probability for Kamala Harris to announce a presidential campaign for the 2028 Democratic nomination is 0.88, which is notably higher than the market's current price of 0.81. This deviation is primarily driven by her position as the sitting Vice President, making her the natural successor and presumed front-runner if the incumbent president does not seek re-election. Her established national profile, experience, and likely party support make an announcement highly probable, even if the path to securing the nomination itself might present challenges. Therefore, the YES outcome appears underpriced.
Will Kamala Harris run for the Democratic presidential nomination in 2028?
My estimated probability that Kamala Harris will announce a presidential campaign for the 2028 Democratic nomination before January 1, 2028, is 0.78, which is notably higher than the current market price of 0.605. This estimate is driven by her current position as Vice President, her demonstrated ambition through a previous presidential run, and the strong likelihood of an open Democratic primary field in 2028 where she would be a prominent contender. While the future is uncertain, the historical pattern for Vice Presidents in such a position suggests a strong propensity to run.
Will Israel and Saudi Arabia normalize relations before Jan 20, 2029?
My estimated probability for Israel and Saudi Arabia normalizing relations before January 20, 2029, is 0.60, which is considerably lower than the market's price of 0.825. While long-term strategic interests and consistent US diplomatic pressure remain strong motivators, the ongoing Gaza conflict has made the Palestinian issue an immediate and high-stakes prerequisite for Saudi Arabia, a condition that will be extremely difficult to meet within the given timeframe, especially considering current Israeli political realities. The market appears to be underestimating the political challenges and the required concessions needed for such a sensitive agreement to materialize.
