Kalshi trades fixed-price yes/no contracts against other traders, not sportsbook-style odds set by a bookmaker. That single difference explains why several bet types a sportsbook customer takes for granted either don’t exist on Kalshi, exist in a different shape, or settle by a different clock entirely.
Anyone moving between a standard sportsbook account and a prediction market needs to know where those gaps sit before placing real money. The differences show up in bet construction, in line granularity, in prop coverage, in state access, and in how a contract resolves when a game doesn’t go to plan.
A sportsbook quotes two-way prices on a line it sets and adjusts. Kalshi instead lists a fixed-price contract, yes or no, and matches buyers against sellers the way a stock exchange matches orders.
That structural choice is the root of everything else in this piece. Products built for a quoted-odds market, like parlays and teasers, don’t translate cleanly onto a contract exchange, and products that do exist on Kalshi are built from separate, individually priced contracts rather than one adjustable line.
Kalshi doesn’t offer a sportsbook-style parlay. Its own term for the closest product is a "combo," and the contract catalog currently lists combo event trading for NFL and NCAAF football only.
When Kalshi first rolled this out, legs could only be stacked within a single game, covering spread, moneyline, total points, and anytime-touchdown-scorer markets. Cross-game parlays weren’t part of it, and the combo builder disappeared shortly before kickoff with no public announcement.
Kalshi’s API files combos under a separate "Exotics" label rather than under its main Sports category. Even with combo fee revenue hitting single-day records around the NFL conference championships, parlay-style volume still makes up a dramatically smaller share of Kalshi’s business than parlay handle does at leading sportsbooks.
A sportsbook teaser moves a line in the bettor’s favor across multiple legs in exchange for worse odds on the combined bet. No reliable source describes anything like that on Kalshi.
What Kalshi lists instead is a full ladder of separate half-point strikes for a given spread, such as a team covering by half a point, by three and a half, by seven and a half, up to sixteen and a half. Each strike is its own yes/no contract with its own price.
There’s no mechanism to shift one of those lines the way a teaser shifts a sportsbook line. A bettor who wants a cushion has to buy a different contract on the ladder, not a discounted version of the same one.
Checked on Oct. 16, 2026 for NFL Week 7, Kalshi’s Patriots-Bears market carried a Chicago -1.5 / New England +1.5 spread contract priced at 52 and 50 percent, alongside a 49.5-point total. That’s the half-point strike convention in practice.
The bigger issue that week was coverage, not pricing. The other 13 matchups on the Week 7 slate had no full-game spread or total contracts listed on Kalshi’s open-market feed at the time of that check.
Kalshi’s NBA board shows the same pattern in a different sport: a spread can be framed as a team winning by more than 4.5 points and a total as a game going over 228.5, with several separate thresholds listed around the same game instead of one central line a sportsbook would post.
A snapshot of Kalshi’s live player-prop board on Sept. 11, 2026 found only a handful of individual contracts live across the entire NFL weekend, including Ja’Marr Chase 7+ receptions, Patrick Mahomes 2+ passing touchdowns, and Jahmyr Gibbs 70+ rushing yards. Each was framed as a fixed-threshold yes/no question, not a line with two-way juice.
Early adoption of anytime-touchdown-scorer props on Kalshi wasn’t huge, according to Gaming Today, which pointed to the limited scope of that initial rollout. The menu has since expanded to passing, rushing, and receiving yardage props, but it still doesn’t match the breadth or consistent liquidity of a sportsbook’s full prop board.
Because Kalshi operates as a CFTC-registered exchange rather than a state-licensed sportsbook, it can reach bettors in states where traditional online sports betting isn’t legal, including Texas and California. One state-by-state tracker lists Kalshi as fully live in more than 40 states plus Washington, D.C., many of which have no licensed sportsbooks at all.
That reach isn’t guaranteed everywhere. The Nevada Gaming Control Board sent Kalshi a cease-and-desist order dated March 4, 2025 covering sports and other event markets, and Kalshi has since asked regulators for more time to respond.
A Michigan judge issued a temporary restraining order on June 29, 2026 over the state-law status of Kalshi’s sports-event contracts. Access through a prediction market is wider in some places than a sportsbook can reach, and narrower in others while legal fights play out.
Kalshi’s NFLOVERTIME rule bases a contract’s outcome on the number of overtime periods actually played. If no official source agency record is available by the contract’s expiration date, Kalshi can wait up to 48 hours before falling back on its payout determination rule.
Under Kalshi’s posted examples, a regular-season game tied after four quarters and decided in one overtime period resolves a count-of-one contract to Yes. A postseason game whose official record shows two overtime periods resolves both a count-of-one and a count-of-two contract to Yes.
For postponements, a football game abandoned before 55 minutes of play, including cancellation before any play happens, settles all contracts to the last fair market price unless the outcome was already determined. A game abandoned after 55 minutes settles based on statistics accumulated up to that point. Kalshi’s general rule for any suspended or postponed game not resumed within 48 hours of its original scheduled start is the same fallback: settle to the last fair market price prior to suspension, unless the outcome has already been decided.
No reliable source spells out a universal, codified tie rule for Kalshi’s NFL spread or moneyline contracts. The documented tie-handling language that does exist covers soccer draw contracts and baseball tie and suspension scenarios, which leaves NFL ties as an open question rather than a published rule.
Kalshi’s player-prop rules settle on actual recorded statistics for any player who takes part in at least one play, even one wiped out by penalty, and that includes players who leave the game after an in-game injury or ejection.
A player who is active but never takes a snap doesn’t get a refund. His props instead settle to the pre-kickoff fair price, meaning the contract resolves based on where the market was pricing it before the game started rather than being voided.
