PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Primary resolution logic:
Associated Press, Fox News, and NBC (all three sources must call the race for the same party)Core resolution logic:
- Market resolves to the political party whose candidate is elected President of the United States in the 2028 election held November 7, 2028
- Resolution occurs when all three sources (AP, Fox News, NBC) call the race for the same party
- If all three sources have not called the race by January 20, 2029 (Inauguration Day), resolution is based on who is inaugurated as President
- Markets are structured as mutually exclusive outcomes: Democratic, Republican, and Other/Third-party categories
- Polymarket includes granular third-party options (Party A through Party L, plus 'another party' catch-all); Limitless uses simplified Democratic, Republican, Other structure
Edge cases & Clarifications:
- Delayed Consensus Among Sources: If AP, Fox News, and NBC do not reach consensus before Inauguration Day, resolution defaults to the party of the inaugurated President, eliminating ambiguity
- Third-Party Victory: Polymarket's 'another party' option and Limitless's 'Other' category both capture non-Democratic, non-Republican outcomes; these are mutually exclusive with major party outcomes
- Constitutional Crisis or No Inauguration: Limitless explicitly addresses the scenario where no individual is inaugurated by January 20, 2029, 11:59 PM ET (resolves to Yes for 'Other' market); Polymarket does not explicitly address this edge case
- Market Granularity Mismatch: Polymarket lists 16 separate questions (named parties A-L plus Democrats, Republicans, and 'another party'); Limitless consolidates to 3 questions (Democratic, Republican, Other). Both are logically consistent but serve different trader preferences
Timing:
Resolution occurs on or after November 7, 2028 (election day) once all three sources (AP, Fox News, NBC) call the race for the same party. If no consensus by January 20, 2029, 11:59 PM ET (Inauguration Day deadline), resolution is based on who is inaugurated. Final resolution deadline is January 20, 2029, 11:59 PM ET.Polymarket

Frequently asked questions
Prediction market odds and traditional polls measure different things. Polls capture voter sentiment at a snapshot in time, while prediction markets reflect traders' real-money bets on the actual outcome. Markets incorporate polling data but also factor in economic conditions, campaign developments, and historical patterns. For the 2028 election, comparing market-implied probabilities to current polling can reveal whether traders expect conditions to shift or whether polls are underweighting certain scenarios. Both tools are valuable for understanding the race.
Limitless and Polymarket can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Price differences between Limitless and Polymarket arise from distinct user bases, liquidity pools, and trading incentives on each platform. Limitless shows 3.0% for its top outcome, while Polymarket reflects different market participation. Variations may also stem from platform fees, settlement confidence, and the specific outcome definitions each market uses. Traders often exploit these spreads by buying low on one platform and selling high on another, though arbitrage friction typically keeps gaps modest.
The market resolves on Nov 8, 2028, following the 2028 US Presidential Election. Resolution is determined by the official winner of the general election as certified by relevant state and federal authorities. The outcome hinges on which party's candidate receives the most electoral votes, as required by the US Constitution. Markets remain active until the result is official and confirmed, ensuring traders can adjust positions right up until resolution.
Major catalysts include candidate announcements and campaign momentum, economic data and employment trends, geopolitical crises or international developments, debate performances and media coverage, primary election results and party consolidation, and polling shifts in key swing states. Unexpected scandals, legislative victories or failures, and demographic shifts can also reshape market expectations. Traders monitor these signals continuously, repricing odds as new information emerges. The market will likely see significant volatility as the election approaches and major events unfold.
