Issue:
Kalshi dataset contains zero CT-01 Democratic primary markets. All six Kalshi entries reference unrelated 2026 races (Maine Senate, Florida Governor, California Governor, Texas Senate runoff). This is a data integrity failure that makes cross-platform comparison impossible.Hero Tip:
Do not attempt to reconcile Polymarket CT-01 markets with Kalshi dropout markets—they are fundamentally different event types in different jurisdictions. Verify Kalshi feed configuration. If Kalshi operates CT-01 markets, retrieve them separately. Proceed with Polymarket CT-01 settlement independently using official Democratic Party sources.Critical Divergence Points:
Polymarket:
22 binary markets on CT-01 Democratic nominee candidates (Candidate A through O, plus named candidates Ruth Fortune, Mark Stewart Greenstein, Jillian Gilchrest, John Larson, Luke Bronin, and 'another candidate'). All resolve per official Democratic Party sources by November 3, 2026, 11:59 PM ET. Primary election: August 11, 2026. Key quote: 'This market will resolve according to the candidate who wins the nomination for the Democratic Party to contest the CT-01 congressional district seat.'Kalshi:
Six dropout/withdrawal markets for unrelated 2026 races: Janet Mills (Maine Senate), James Fishback (Florida Governor), Chad Bianco (California Governor), Eric Swalwell (California Governor), Ken Paxton (Texas Senate runoff), John Cornyn (Texas Senate runoff). Zero CT-01 content. Key quote: 'If [candidate] drops out of the 2026 [state] [race] primary/runoff before [date], then the market resolves to Yes.'

Kalshi
A candidate drops out when they announce they are ending, suspending, or withdrawing from their campaign; file official withdrawal paperwork; publicly state they are no longer seeking the office; or endorse another candidate while stating they are no longer running. Campaign suspension counts as dropping out unless the candidate explicitly states they remain in the race. Death or incapacitation does not constitute dropping out. Losing a primary or general election, failing to qualify for debates or ballots, or being eliminated through normal election processes does not count as dropping out. Once a candidate drops out, the market resolves Yes even if they later re-enter the race. Each market resolves Yes if the specified candidate drops out before their respective deadline: Janet Mills (Maine Senate, June 9, 2026), James Fishback (Florida Governor, August 18, 2026), Chad Bianco (California Governor, June 2, 2026), Eric Swalwell (California Governor, June 2, 2026), Ken Paxton (Texas Senate runoff, May 26, 2026), and John Cornyn (Texas Senate runoff, May 26, 2026).
Frequently asked questions
Prediction markets and polls measure different signals. Polls capture voter preference at a snapshot in time, while prediction markets reflect traders' beliefs about the actual outcome, incorporating private information, campaign momentum, and real-money incentives. Markets often move ahead of polls when new information emerges—endorsements, debate performance, or fundraising milestones. For the ct-01 democratic primary winner, market odds may diverge from polling if traders believe polls are outdated or miss late-breaking developments. Markets tend to be more dynamic and forward-looking than traditional surveys.
This market resolves on Aug 18, 2026. Resolution hinges on the official outcome of the Connecticut 1st District Democratic primary election. Each platform will settle based on the certified winner announced by Connecticut election authorities. Traders should monitor primary date announcements, candidate filings, and any changes to the electoral calendar. The exact resolution criteria are set by each platform's terms; check the specific market rules on Kalshi and Polymarket for settlement details.
Major catalysts for the ct-01 democratic primary winner include candidate endorsements from party leadership, debate performances, fundraising reports, and polling releases. Unexpected candidate entries or withdrawals will shift odds sharply. Local media coverage, voter registration trends, and turnout models also influence trader positioning. National political events—shifts in Democratic strategy or messaging—can ripple into district-level races. Campaign spending surges, opposition research drops, or gaffes may trigger rapid repricing. Watch for early voting data and internal campaign polling leaks as the primary approaches.
