Republican Presidential Nominee 2028
I assess a low but non-negligible probability that Donald Trump will win and accept the 2028 Republican presidential nomination, largely because of his persistent influence in the party but tempered by legal, health, and competitive obstacles.
Analysis
Market prices imply an extremely low chance (about 2%) that Trump will be the 2028 GOP nominee, reflecting strong market conviction that either he will not run, will be unable to secure delegates, or will be sidelined by legal or health events. The very large event volume indicates the market is well-trafficked and that this low price has been actively traded and defended, which matters as a baseline but is not determinative of future shifts.
Historically, Trump has unique strengths: two prior Republican nominations (2016, 2020) and a mobilized base that has repeatedly dominated Republican primaries, which increases his upside if he chooses to mount a campaign and if legal/health barriers do not terminate his bid. However, the party dynamics in 2026-2028 could be very different from prior cycles because Republican leaders and donors who previously tolerated Trump may prefer a fresh standard-bearer to improve general-election prospects, and prominent governors and senators could consolidate support behind an alternative.
The decisive external factors over the next two years are likely to be (1) whether Trump announces and actively pursues a 2028 campaign, (2) the outcomes of any legal proceedings or criminal convictions that could limit his ability to campaign or change delegate calculus, and (3) the emergence of a credible, unified alternative candidate supported by establishment donors and state party organizations; each of these can rapidly move probability up or down from the current baseline. Given these intersecting forces, I place a low probability (8%) on Trump winning and accepting the nomination because his structural advantages exist but are currently outweighed by practical obstacles and credible alternatives within the party.
Arguments
For
- Trump retains a large and loyal base within the Republican electorate that can dominate low-turnout primaries.
- He has proven experience winning the GOP nomination twice and understands how to navigate delegate mechanics.
- Name recognition and media dominance would allow rapid re-entry into a national primary race if he chooses to run.
- If alternative candidates split the anti-Trump vote, a plurality strategy could deliver him the nomination.
Against
- Ongoing or future legal liabilities and potential convictions create a major hurdle to mounting a conventional campaign.
- Age and health concerns will be salient to many delegates and donors and could suppress his viability as a nominee.
- Republican elites and major donors may coordinate behind a single alternative to avoid a repeat of intra-party turmoil.
- If Trump chooses not to run or accepts a role as kingmaker rather than candidate, he loses the nomination by default.
Key drivers
- Whether Donald Trump announces a serious campaign for the 2028 nomination and commits time and resources to it.
- Legal outcomes including indictments, convictions, or sentencing that could impair his campaign capacity or political standing.
- The emergence of one or more strong GOP challengers who can consolidate donor, media, and state-party support.
- Republican primary calendar and delegate rules that influence whether a plurality or convention fight decides the nominee.
- Health and age considerations that could affect voters, delegates, and Trump’s own willingness to accept the nomination.
- RNC leadership and influential state party actors' preferences and any rule changes they adopt ahead of 2028.
Risk factors
- Trump formally declines to run or decides to retire from electoral politics before the primaries.
- Convictions or legal penalties that restrict his mobility, campaign operations, or political viability.
- A strong, well-funded challenger coalesces early, capturing donor networks and institutional endorsements.
- Major health event or incapacitation that prevents campaigning or leads to refusal to accept a nomination.
- Changes in RNC rules or delegate allocation that disadvantage Trump-style primary strategies.
- A sustained shift in Republican primary voter preferences away from Trump toward electability-focused candidates.
Scenarios
Best case
Trump announces a full campaign, legal issues are minimal or resolved in his favor, establishment challengers split the field, and his base secures a delegate plurality that he converts into the nomination which he publicly accepts.
Most likely
Trump contemplates or attempts a 2028 bid but faces significant headwinds from legal issues, age concerns, and organized donor/party opposition that leave him with a small residual path to the nomination that is unlikely to succeed, producing a low but nonzero chance of him winning and accepting the nomination.
Worst case
Trump either declines to run, is legally barred or effectively incapacitated by convictions or health problems, or is politically abandoned by the party leading to a different nominee and a clear 'No' resolution.

What will the average number of measles cases be during Trump's term?
AI72%MKT30%Edge+42Hidden GemAssuming 'Yes' means the *average annual* number of U.S. measles cases across 2025–2028 is at least 1,000, I assign a 72% probability that it will be Yes — I view the large 2026 wave plus systemic policy and global-health disruptions as more likely than not to push the multi-year average above 1,000.
