Frequently asked questions

Prediction market odds on Kalshi often diverge from traditional polling averages because markets incorporate real-money incentives and forward-looking trader expectations. While polls capture voter sentiment at a single moment, prediction markets aggregate information from participants betting on actual outcomes through Nov 3, 2026. Markets may price in campaign momentum, fundraising strength, or endorsement effects faster than polls update. Comparing Kalshi odds to recent CA-10 primary polls reveals whether traders are more bullish or bearish on specific candidates than survey respondents indicate, offering a complementary lens on race dynamics.

The CA-10 primary: Who will advance market resolves on Nov 3, 2026, following the official California primary election date. Resolution is determined by which candidates officially advance from the primary contest according to California election law and certified results. The market tracks advancement eligibility based on vote totals and state-specific rules governing how many candidates proceed to the general election. Once official results are certified and announced, the market settles based on the actual advancement outcomes for each candidate in the CA-10 race.

Several catalysts could shift CA-10 primary odds before Nov 3, 2026. Major campaign announcements, candidate endorsements from prominent state or national figures, and debate performances typically trigger sharp price moves. Fundraising reports and cash-on-hand disclosures signal candidate viability and resources. Local media coverage, voter registration surges, and grassroots organizing intensity all influence trader expectations. Unexpected candidate withdrawals or entries reshape the field. National political developments affecting congressional races, demographic shifts in the district, or scandal revelations can rapidly reprrice advancement odds. Early voting and mail-ballot returns in the final weeks often drive the largest market adjustments as real voter behavior becomes visible.
