How to read: Prediction market prices represent the cost in cents to buy one share. A price of 65¢ means the market implies a 65% probability. If the event occurs, the share pays out $1.00 (100¢). Enter a price above or any odds format to convert instantly.
Kalshi is the first federally regulated prediction market exchange in the United States, designated by the Commodity Futures Trading Commission (CFTC). Instead of using traditional betting odds, Kalshi prices event contracts between 1¢ and 99¢, where the price directly represents the market's implied probability.
Enter a Kalshi contract price above to convert it to American, decimal, or fractional odds — or enter odds in any format to find the equivalent Kalshi price.
Kalshi operates as a regulated exchange where users buy and sell event contracts. Each contract is a simple Yes/No question about a future event, and the contract price reflects the crowd's consensus probability.
Here's how to interpret a Kalshi contract:
This is equivalent to placing a bet at -122 American odds (or 1.82 decimal odds). You're risking $55 to win $45 in profit.
| Kalshi Price | Implied Probability | American Odds | Decimal Odds |
|---|---|---|---|
| 10¢ | 10% | +900 | 10.00 |
| 20¢ | 20% | +400 | 5.00 |
| 25¢ | 25% | +300 | 4.00 |
| 33¢ | 33% | +200 | 3.03 |
| 40¢ | 40% | +150 | 2.50 |
| 50¢ | 50% | +100 | 2.00 |
| 55¢ | 55% | -122 | 1.82 |
| 60¢ | 60% | -150 | 1.67 |
| 70¢ | 70% | -233 | 1.43 |
| 75¢ | 75% | -300 | 1.33 |
| 80¢ | 80% | -400 | 1.25 |
| 90¢ | 90% | -900 | 1.11 |
Unlike traditional sportsbooks, Kalshi operates under federal regulation by the CFTC. This means:
Traditional sportsbooks like DraftKings, FanDuel, and BetMGM embed a margin (vig or juice) into their odds, typically 4-10%. This inflates the implied probabilities so the book profits regardless of the outcome.
Kalshi's exchange model is different. The platform charges a small fee on winning trades (typically around 1¢ per contract), but prices are set by market participants — not by a house that needs to maintain a margin. Because of this, Kalshi pricing may track closer to estimated true market probabilities than sportsbook odds, though no market is a guaranteed predictor of outcomes.
If Kalshi prices an event at 55¢ (implying 55% probability) and a sportsbook offers the equivalent outcome at -130 American odds (implying approximately 57% probability with vig), the Kalshi price may offer better value. Conversely, if the sportsbook's devigged odds imply a lower probability than Kalshi's price, the sportsbook could be the sharper play.
This kind of cross-platform odds comparison is what the SmartStake Arbitrage Finder automates — scanning 30+ sportsbooks in real time to surface candidate discrepancies. Arbitrage betting is not risk free and results are never guaranteed.
Kalshi offers event contracts across a wide range of categories:
Because Kalshi is a regulated exchange, contracts are available for events that sportsbooks typically don't cover — making it a unique source for pricing on non-sports outcomes.
Suppose Kalshi has a contract asking "Will a Category 4+ hurricane make US landfall in 2025?" priced at 28¢.
Using the converter:
Since weather events are rarely available on traditional sportsbooks, Kalshi offers a unique market. But for events that do overlap — like the Super Bowl winner — you can compare Kalshi's pricing to sportsbook odds to find the best value.
Say Kalshi has "Will the Kansas City Chiefs win the Super Bowl?" at 22¢ (+355 American odds). Meanwhile, DraftKings lists the Chiefs at +400.
In this case, DraftKings offers better odds (+400 vs. +355). But remember — Kalshi's fee structure is different. Factor in trading fees on both platforms to determine where your expected value is highest.
Kalshi's regulated event contracts give you access to markets that traditional sportsbooks can't offer. By converting contract prices to familiar odds formats, you can evaluate whether the prediction market or a sportsbook gives you the best edge.
