Intro

This market tracks who will become the Republican Party's presidential nominee for the 2028 election. Across Polymarket, Kalshi, and Limitless, the consensus shows Ron DeSantis at 49.5% and Ted Cruz at 49.5%, with resolution determined by official Republican Party sources including convention proceedings and announcements. The nominee must both win the nomination and accept it to trigger a Yes resolution. Watch the Republican National Convention scheduled for summer 2028, where the official nomination will be decided.

Unified Resolution Criteria (Consistent across platforms)

All three platforms (Kalshi, Polymarket, Limitless) apply identical core logic: a candidate must win and accept the 2028 Republican nomination, with resolution sourced from official Republican Party sources, and post-election-day replacements do not alter resolution.

Primary resolution logic:

Consensus of official Republican Party sources, including convention proceedings and party announcements

Core resolution logic:

  • Candidate must win the 2028 Republican Party presidential nomination
  • Candidate must accept the nomination
  • Resolution determined by official Republican Party sources
  • Only one nominee can resolve to Yes across all individual candidate markets
  • All non-winning candidates resolve to No
  • Replacement of nominee after election day does not change resolution
  • The 'Other' market resolves Yes if winner is not among named candidates or nominee unknown by deadline

Edge cases & Clarifications:

  • Replacement after election day: If the Republican nominee is replaced after election day, the resolution does not change. The original winner who accepted the nomination determines the resolution.
  • Nominee unknown by deadline: If the Republican nominee is not known by November 7, 2028, 11:59 PM ET, the 'Other' market resolves Yes and all named candidate markets resolve No.
  • Acceptance requirement: A candidate must both win the nomination AND accept it. Winning without acceptance does not trigger a Yes resolution.
  • Multiple named candidates: Kalshi lists 35 named candidates, Polymarket lists approximately 40+ named candidates (including placeholder 'Person' codes), and Limitless lists 8 named candidates. Only one can resolve Yes; others resolve No.
  • Placeholder persons in Polymarket: Polymarket includes coded placeholders (Person CX, Person AD, etc.) whose identities are not disclosed in source data. These resolve based on the same criteria as named candidates.

Timing:

Resolution occurs upon official Republican Party announcement and acceptance of the 2028 presidential nominee. Deadline for 'Other' market is November 7, 2028, 11:59 PM ET.

Frequently asked questions

This dashboard aggregates real-time odds and trading volume for the Republican Presidential Nominee 2028 across Kalshi and Limitless, two of the largest prediction markets. It tracks which candidate the market believes is most likely to secure the Republican nomination heading into the 2028 general election. The combined group has processed over $701,644,690 in total volume, with $779,916 traded in the last 24 hours. By monitoring both platforms simultaneously, you see consensus views and spot divergences that may signal shifting sentiment among professional traders and political forecasters.

Prediction markets and polls measure different things. Polls capture voter preference at a snapshot in time, while prediction markets reflect traders' beliefs about the actual nomination outcome, incorporating insider information, campaign momentum, and financial incentives. Markets often move faster than polls and can price in events before they register in surveys. For the 2028 Republican nomination, comparing market odds to contemporaneous polling can reveal whether the frontrunner in markets aligns with public preference or whether traders are betting on a different outcome based on delegate math, party dynamics, or candidate viability.

Kalshi and Limitless can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform attracts different trader demographics, liquidity pools, and fee structures. Kalshi and Limitless may have different order books, leading to price gaps on the same candidate. Timing matters too: a major news event may move one platform faster than the other. Market depth, minimum bet sizes, and user interface also influence where traders concentrate capital. These differences create arbitrage opportunities and mean that checking both platforms gives you a fuller picture of market consensus on who will win the Republican nomination.

The market resolves on Nov 8, 2028, the date of the 2028 general election. The outcome is determined by who the Republican Party officially nominates as its presidential candidate. This typically happens at the Republican National Convention, held in the summer before the general election. Once the nominee is formally announced and confirmed, the market settles based on that official designation. Traders should monitor convention dates, delegate counts, and party announcements throughout the primary season to track the path to nomination.

Major catalysts include primary election results, debate performances, endorsements from party leaders, campaign funding announcements, and candidate withdrawals. Unexpected scandals, health issues, or gaffes can shift odds rapidly. Delegate counts and state-by-state primary outcomes directly influence nomination probability. National economic conditions, geopolitical events, and shifts in voter sentiment also matter. Media coverage and polling momentum feed into trader decisions. Watch for convention rule changes, brokered convention scenarios, and last-minute candidate entries or exits. Each of these events can trigger significant repricing across both Kalshi and Limitless.
