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 first individual Donald Trump announces as his pick to be United States Food and Drug Administration (FDA) Commissioner. An announcement from Donald Trump or the Trump administration stating their intent to nominate a specific individual to be United States Food and Drug Administration (FDA) Commissioner will suffice to resolve this market, regardless of whether a formal nomination actually occurs. Qualifying announcements must explicitly present the relevant individual as the nominee or future nominee for FDA Commissioner. Announcements of acting or interim appointments, or announcements which merely reveal potential candidates, will not qualify. Media reports, speculation, or other unofficial information will not qualify. A formal presidential nomination of an individual to be United States Food and Drug Administration (FDA) Commissioner will also suffice to resolve this market. Formal nominations are defined as the submission of a nomination message to the U.S. Senate. If Donald Trump does not announce his pick for the next United States Food and Drug Administration (FDA) Commissioner by December 31, 2026, 11:59 PM ET, this market will resolve to “No announcement by December 31”. The resolution source for this market will be official information from Donald Trump and the Trump Administration; however, a consensus of credible reporting may also be used.
ⓘ 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.

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.

Democratic Presidential Nominee 2028
The field is moderately concentrated with Newsom and Ocasio-Cortez combining for 66%, but the 21% for both Buttigieg and Harris and a 23% 'Other' share show significant latent openness; the biggest recent shift is the DNC's decision to put South Carolina first in 2028 (NYT, Jul 24), which could reshape candidate strategies and delegate math.

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.
