Pronóstico: HI-01 Democratic Primary Winner

Platform comparison

Market context

Hawaii’s 1st Congressional District Democratic primary is the contest that will decide the party’s nominee for the U.S. House seat, and the market’s 0% implied probability on YES is hard to reconcile with the fact that the ballot is already set and the primary is a fixed-date event. Official election materials show the Democratic primary on 8 August 2026, with Ed Case, Jarrett Keohokalole, Jennifer Booker, Ben Fatula and Nicholas Kiswanto among the declared candidates.[1][7]

For context, HI-01 has been a low-turnout, incumbent-friendly Democratic race in recent cycles. Ed Case won the 2024 Democratic primary decisively, and he also took the nomination in 2022, which frames the race as one where an established incumbent or well-known local officeholder usually starts from strength rather than a blank slate.[13] Recent polling and market reads have still treated Case and Keohokalole as the main pair to watch, with Case generally ahead but not unchallenged, while lesser-known candidates have remained outside the main pricing band.[2][3]

The main catalysts now are final vote reporting, any last-minute candidate withdrawals or ballot status changes, and whether the official Democratic sources confirm a nominee by the market’s settlement deadline. The election calendar and ballot filings are already in place, so there is little procedural room for surprises unless a post-election dispute or missing announcement pushes the result towards “Other” under the market rules.[1][7][9] Traders should also watch whether late reporting confirms the expected incumbent-versus-challenger split or produces a narrower-than-expected finish.[8]

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
