How it resolves
Settled on-chain by UMA's optimistic oracle: once an outcome is clear, anyone can propose the result, which then enters a challenge window where it can be disputed with evidence before it finalizes.
⚖️ A proposed outcome can be disputed during a challenge window before it's final.
Resolution criteria
This market will resolve according to the party of the candidate who wins the CA-10 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 3, 2026. A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources. This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.

Democratic Presidential Nominee 2028
The field is virtually nonexistent: only two candidates register at 1% each, and no one has broken 5%, making this the most open Democratic nomination race in modern history. The single biggest recent shift is the DNC's decision to put South Carolina first in the 2028 primary calendar (Axios, Jul 25), which could reshape candidate strategies and favor a different type of contender.

Fed Decision in July?
The field is overwhelmingly concentrated on 'No change' at 80%, with a 24-hour +1pt drift, but the recent MarketWatch headline reveals deliberate Fed communication opacity—Chair Warsh is keeping markets in the dark, which paradoxically reinforces the no-change baseline as the safe anchor while leaving room for a surprise 25bps hike (19%) if incoming data forces clarity. The single biggest recent shift is the slight uptick in 'No change' odds, likely reflecting traders pricing in the Fed's strategic ambiguity as a signal of no urgent action.

Next General Election - Most Seats
The field is moderately concentrated with Labour leading at 36%, but Reform UK and Conservative are close; the biggest recent shift is Reform UK overtaking the Conservatives for second place, as seen in the stated odds, though no headline directly explains this.

Republican Presidential Nominee 2028
The Republican nomination market is essentially a blank slate with no declared candidate, as the combined odds of the two listed figures (Byron Donalds at 1%, Mike Pence at 0%) barely exceed 1%, indicating the race is wide open for any major figure to enter and become the immediate front-runner.

2028 Presidential Election Winner
The field is unusually fragmented with no candidate above 18%, and the top three sum to just 41%, reflecting a wide-open race where the biggest recent shift is the absence of a clear front-runner despite ongoing midterm elections and controversies over election integrity. The 2026 primary results (NBC News, Jul 23) are reshaping candidate viability, but no single contender has consolidated support yet.

Brazil’s Next President Elect
The race is a two-person contest between Lula and Flávio Bolsonaro, with Lula consistently widening his lead in recent polls (Reuters, Jul 1, Jun 16, Jun 10), making a third-party upset highly unlikely in the near term.
