How PlayDelta reads Kalshi sports markets.
The public board shows available NFL, college-football and MLB game-winner quotes. Eligible MLB and NFL pregame matchups also receive separate, experimental probability estimates.
Independent research · 21+ · last reviewed September 28, 2026A quote comes from the exchange.
The ask is a seller’s quoted price; the bid is a buyer’s quoted price. A 62¢ Yes ask can be read as a 62% price-implied reference. It is not PlayDelta’s estimate of the outcome, and the displayed price does not guarantee a fill.
Kalshi’s order-book guide · How prices relate to probabilities
A separate estimate for eligible games.
The public MLB and NFL models use completed team results, without market prices as inputs. Comparisons require a supported game, an unambiguous matchup, fresh data, and a verified pregame start time. College-football quotes do not imply a connected probability model.
Model probability minus the same outcome’s ask.
An estimated 55% win probability against a 52¢ Yes ask produces a +3 percentage-point gross gap. This comparison is before fees and does not establish a profitable edge. Model error, available quantity, price changes and contract terms can affect any trading result.
The MLB model does not account for starting pitchers, confirmed lineups, injuries, park, weather or in-game score. Its 2025 test did not beat the simpler Elo comparator. The NFL model does not account for starting quarterbacks, injuries, weather or live game state. Read the methodology and historical results, or review Kalshi’s current fee information.
Unavailable stays unavailable.
A fixture may remain visible when its current quote is missing. Missing or stale inputs do not become a price, model estimate or gap. MLB and NFL comparisons expire when the game starts; they are pregame forecasts.
Forecasts have a public scorecard.
The model scorecard shows saved MLB and NFL forecasts and actual outcomes. It separates recorded, graded, pending and excluded games, with verified winners and final scores. Its probability metrics measure how well the saved forecasts match the results. A small sample cannot establish a dependable advantage.
