Kalshi Odds Explained: How To Read Cents, Probability, And American Odds

Kalshi odds do not look like anything a sportsbook shows you. There is no -110, no +260, no moneyline at all. There is a single number between 1 and 99, quoted in cents, and that is the whole quote. It looks foreign, and that foreignness is exactly why most people bounce off the exchange before they realize the truth: a Kalshi price is the easiest odds format to read, because it starts from the one number every other format makes you calculate: the implied probability.

That number is a probability. A contract trading at 65 cents is the market pricing the event at about 65%, the cleanest read of a probability any odds format gives you, before you layer in fees and spread. Sportsbook odds bury that probability inside vig and dress it up as +150 or -186; Kalshi just prints it. Once you see that, reading the board becomes translation rather than decoding, and translation is easy. This page is the whole dictionary: the conversion chart both directions, the formula you can do in your head, and the two things the raw cent price quietly refuses to tell you.

Because there are two, and they are where beginners lose money. The price is your break-even probability before Kalshi's trading fee, and a Kalshi "winner" contract does not always settle on the same rules as a sportsbook moneyline. Hold both of those in mind. I will pay them off once the conversion itself is second nature.

In Summary

• The Cent Price Is The Implied Probability. A Kalshi contract settles at $1.00 or $0.00, so a 60-cent price means the market prices the event at 60%. No other odds format hands you the probability that directly.
• 50 Cents Is The Pivot. Below 50¢ the contract is an underdog (positive American odds); above 50¢ it is a favorite (negative American odds). 50¢ is exactly +100, an even-money coin flip.
• Cents To American, Above 50¢: -(P / (100 - P)) x 100. Below 50¢: ((100 - P) / P) x 100, where P is the price in cents. So 60¢ = -150 and 40¢ = +150 — the chart mirrors around the 50¢ line.
• American Back To Cents: a favorite priced -X implies X / (X + 100); an underdog at +Y implies 100 / (Y + 100). Multiply by 100 for the cent price.
• The price is your break-even before fees. Kalshi's trading fee raises your true break-even above the sticker price. A 63¢ contract reads like -170, but with the fee it behaves closer to -186.
• Settlement Can Differ From A Sportsbook. A Kalshi contract grades on its own written rules. A postponement void or a prop's exact cutoff can make a same-looking bet a different one. Read the contract before treating its price as a moneyline.
• Where OddsShopper Fits: our no-vig fair-odds pricing strips the margin out of a sportsbook line so you get its true probability, which is the only apples-to-apples way to judge a Kalshi cent price against the book.

One framing note before the math. Kalshi is a CFTC-regulated exchange, and its products are event contracts, not sportsbook wagers. That is a real legal distinction, not marketing. It is why the price shows up as a tradeable contract instead of a moneyline, and why availability by state follows different rules than a sportsbook. Nothing here is a promise of profit; fees, spreads, and thin markets are real costs, and a clean conversion does not make a trade a good one.

Why A Kalshi Price Is Already A Probability

Start with the mechanic that makes everything else fall into place. Every Kalshi contract resolves to one of two values: $1.00 if the event happens, $0.00 if it does not. That is a binary payout, and a binary payout has a tidy property: the price a rational market pays for it is the probability it assigns.

The OddsShopper Arbitrage Tool.

If the market thinks an outcome is 60% likely, a contract that pays $1.00 on a win is worth 60 cents. Pay more and you are overpaying for the probability; pay less and you are getting a bargain on it. So the quote you see, 60¢, is not a price that implies a probability the way -150 does. It is the probability, priced in dollars — before fees and spread. A 7-cent contract is priced as a 7% shot. A 92-cent contract is priced as a 92% outcome, a very heavy favorite.

This is the entire reason Kalshi odds confuse newcomers and then, thirty seconds later, feel obvious. You already know how to read a percentage. A sportsbook makes you convert -150 into "60% break-even" in your head before the number means anything; Kalshi skips the conversion and shows you the 60. Everything below is just re-dressing that percentage into the formats you are used to.

Kalshi Odds Conversion Chart: Cents, Probability, And American Odds

Here is the full board, from longshot to near-certainty. The middle column is the cent price read straight as a probability; the right column is the same position expressed as American odds, the way a sportsbook would quote it.

Kalshi Price	Implied probability	American odds	Read
5¢	5%	+1900	Deep longshot
10¢	10%	+900	Longshot
20¢	20%	+400	Underdog
25¢	25%	+300	Underdog
30¢	30%	+233	Underdog
35¢	35%	+186	Slight dog
40¢	40%	+150	Slight dog
45¢	45%	+122	Near coin flip
50¢	50%	+100	Coin flip (pivot)
55¢	55%	-122	Slight favorite
60¢	60%	-150	Favorite
65¢	65%	-186	Favorite
70¢	70%	-233	Solid favorite
75¢	75%	-300	Strong favorite
80¢	80%	-400	Heavy favorite
90¢	90%	-900	Very heavy favorite
95¢	95%	-1900	Near-certainty

The single most useful row is the bold one in the middle. At 50 cents the contract is a pure coin flip, +100, even money, and it is the mirror line for the whole chart. Notice that 60¢ (-150) and 40¢ (+150) are reflections of each other, and so are 65¢ (-186) and 35¢ (+186). Every favorite price has an underdog twin the same distance from 50, carrying the same American number with the sign flipped. Learn one half of the board and you have learned both.

The way I actually use this at the board is to anchor on 50¢ and read only the distance from the pivot, because that distance is where cent moves get deceptive. A contract at 57¢ does not feel far from a coin flip, but it converts to roughly -133 before fees — so a seven-cent nudge off the pivot is already a price a book-shopping edge can erase. Small-looking moves on the cent scale are larger than they look once you translate them, which is the entire argument for converting deliberately instead of eyeballing.

The Formula: Kalshi Price To American Odds, Both Directions

The chart covers the common prices, but you will eventually want a number that is not on it, so here is the math. It is two short rules, split at the 50-cent line, with P as the price in cents.

Cents to American odds:

Price above 50 (favorite):   American = -(P / (100 - P)) x 100
Price below 50 (underdog):   American = ((100 - P) / P) x 100

At exactly 50¢ the two rules meet at +100 — even money, the coin flip.

Run 65¢ through the favorite rule: -(65 / 35) x 100 = -186. Run 35¢ through the underdog rule: ((100 - 35) / 35) x 100 = +186. Those match the chart, which is the point — the formula and the table are the same tool at different resolutions.

American odds to Kalshi cents. Going the other way is a two-step: turn the American odds into a probability, then read that probability as cents.

Favorite (-X):   probability = X / (X + 100)
Underdog (+Y):   probability = 100 / (Y + 100)
Cent price = probability x 100

A sportsbook showing -150 implies 150 / 250 = 0.60, or 60 cents on Kalshi. A +250 dog implies 100 / 350 = 0.286, about 29 cents. This is the direction you use to evaluate a price rather than just read one, because it is how you spot a gap: convert the book's line to a cent-equivalent, look at what the same outcome trades for on the exchange, and the difference is a potential edge — or the sign that the book is the better price. A gap is a reason to look closer, not a guaranteed profit; fees, spread, and settlement rules all still have to clear before it is real. If you also want decimal and fractional in the mix, our general odds converter handles all three formats side by side.

Worked Example: Reading A Real Kalshi Market

Say an NFL team's "to win" contract is trading at 63 cents. Walk it through the way I would at the board.

First, the probability: 63 cents is a 63% implied chance, no conversion needed. Second, the American translation, so I can compare it to my sportsbook: -(63 / 37) x 100 = -170. Now I have a like-for-like number. If DraftKings has the same team at -165 and FanDuel has them at -175, the exchange price sits right in the middle of the market — reasonable, not a steal.

Here is where the raw price starts lying to you, and it is the first promise coming due. That -170 is what the sticker implies. It ignores Kalshi's trading fee, which is charged on top of the contract price and is heaviest near coin-flip prices. On this contract the fee adds roughly two cents of real cost, which pushes your effective entry toward 65 cents — and 65 cents, run through the same formula, is -186. So the honest translation of a 63¢ Kalshi contract is not -170. It is closer to -186 once you are paying to get in. The full mechanics of that curve live in our Kalshi fees breakdown, but the one-line version is this: when a trading fee applies, it makes your real odds worse than the screen price, and by the most near a coin flip.

That gap is the whole reason to convert carefully instead of eyeballing. A -170 that is really -186 can flip a "slight edge over the book" read into "the book was cheaper all along."

What The Chart Hides: Fees Move Your Real Break-Even

The conversion chart is the truth about the price. It is not the truth about your break-even, and conflating the two is the most expensive beginner mistake on the exchange.

Your break-even probability is the win rate you need just to not lose money. On a raw 60-cent contract, that break-even is 60% — the price and the break-even are the same number, which is the elegant part. Add the fee and they separate: you paid 60 cents plus a fee, so you actually need to win slightly more than 60% of the time to profit. The fee does not change the probability the market is quoting; it changes the price you paid for it, and price is what break-even is built on.

This is exactly the muscle a sharp bettor already uses on sportsbook vig, and it is worth naming the parallel. A -110 line implies 52.4%, but two -110 sides add to about 104.8%. The extra 4.8 points is the book's hold, its margin baked into the price. On a Kalshi market the equivalent cost is not baked in; it is the visible trading fee, charged separately and sitting mostly around the middle of the board. Different plumbing, same idea: the number on the screen is never your true break-even until you have added the cost of doing business. This is why I run both a book line and a contract price through the real math before deciding, rather than trusting whichever venue looks cheaper at a glance.

Settlement: A Kalshi Winner Is Not Always A Moneyline

The second promise, and the subtlest one. Two contracts can read identically — "Team X to win," 63 cents, -170 after your conversion — and still be different bets, because they can settle on different rules.

A sportsbook moneyline almost always grades on the final score including overtime. A Kalshi event contract grades on whatever its specific rules say, and those rules are written per market, not assumed — a contract can void on a postponement, resolve on a precisely defined condition, or carry a player-prop cutoff that is not "who won the game as you would describe it at the bar." Whether something like overtime counts is a question to check in the rulebook, not to assume from the sportsbook version. The conversion math tells you the price is equivalent; it does not tell you the bet is equivalent.

So the last step of reading Kalshi odds is not a formula at all. It is reading the contract's settlement terms before you treat its price as interchangeable with a sportsbook number. Often they line up, but the exceptions are exactly where an arb that looked airtight quietly turns into two separate, uncorrelated bets — which is the trap our prediction market arbitrage guide is built to help you avoid.

Where To Compare: No-Vig Fair Odds Vs A Kalshi Price

Everything above gets you from a Kalshi cent price to an American number you recognize. The harder question — is that price actually good? — needs the other side of the trade, and that is where a de-vig tool earns its keep.

A sportsbook's line is not a probability; it is a probability plus the book's margin. To compare it honestly to a Kalshi price, you have to strip that margin out. For a supported two-way market, the tool surfaces the no-vig, fair-odds version: the odds screen takes both sides of a book's line, removes the margin baked into that price (the book's hold, which varies by sport, market, and book), and estimates the sportsbook's true implied probability.

Run the earlier example through it. Say that same NFL team is -170 at DraftKings and the other side sits at +150. Those two prices imply about 63.0% and 40.0%, which sum to roughly 103% — the extra three points are the hold. De-vig them and the team's fair probability lands near 61%, or about 61 cents. Now the comparison is clean: 61 cents fair at the book versus the 63-cent contract on Kalshi with its fee included. Same event, two probabilities you can finally read side by side, instead of one honest number against one loaded one.

The practical move is simple: convert the book, convert the contract with the chart above, then compare the real prices. The same odds screen runs line shopping across 100-plus books, an EV calculator prices any number as a probability, and the arbitrage tool flags the spots where an exchange price and a de-vigged book price disagree enough to matter. If you would rather start from someone else's homework, our free expert picks today show the same discipline applied to live markets.

Before You Trade: State Rules And Eligibility

Kalshi's availability is not the same map as a sportsbook's, and the map is being redrawn in court in real time. As a CFTC-designated exchange, Kalshi operates in 40-plus states, and in some places where sportsbooks are not legal at all. The mechanism driving that is federal preemption. In an April 2026 ruling, a federal appeals court (the Third Circuit) sided with Kalshi on Commodity Exchange Act preemption, holding the CFTC likely has exclusive jurisdiction over sports event contracts; that decision blocked New Jersey from enforcing its gambling law against the exchange and keeps contracts live in that circuit while the case heads toward possible en banc or Supreme Court review. Other states have pushed the opposite direction, with sports contracts paused, restricted, or under active enforcement disputes in places such as Arizona, Nevada, and Ohio as of our July 2026 check. The point is not the exact roster on any given week — it is that this list shifts on court rulings, sometimes fast. Because prediction-market legality is different from sportsbook legality, do not assume your state's sports-betting status tells you anything here. Check Kalshi's own eligibility tool on the day you fund an account, and see are prediction markets legal for the wider picture.

Minnesota, specifically. A Minnesota law effective August 1, 2026 makes it a felony to create, operate, host, or advertise a prediction-market platform in the state. It targets platforms and operators, not individual traders, and it is under active litigation — but the practical result for a Minnesota resident is that these markets are expected to stop being offered there. We do not encourage anyone in Minnesota to trade these contracts. Get current local guidance rather than relying on this paragraph.

Kalshi Odds FAQ

How do Kalshi odds work? Kalshi quotes every market as a single price between 1 and 99 cents, and that price is the implied probability of the event. A contract settles at $1.00 if the event happens and $0.00 if it does not, so a 70-cent price means the market thinks the outcome is 70% likely. To compare it to a sportsbook, convert the cent price to American odds with the formula above.

How do I convert a Kalshi price to American odds? Split at 50 cents. For a price above 50, American odds = -(P / (100 - P)) x 100; below 50, American odds = ((100 - P) / P) x 100, with P in cents. Exactly 50 cents is the pivot, +100 even money. A 60-cent contract is -150; a 40-cent contract is +150. The chart above lists the common prices both ways.

What does a 65-cent Kalshi contract mean? It means the market prices the event at 65%, which converts to -186 in American odds. Note that this is the price before Kalshi's trading fee — once the fee is added, your effective break-even is slightly higher than 65%.

Is a Kalshi price the same as a sportsbook probability? The cent price is a clean implied probability, but a sportsbook line is a probability plus the book's margin (its vig). To compare them fairly you have to de-vig the book line first, which is what OddsShopper's no-vig fair-odds pricing does. Only then are you comparing two like numbers.

Does the Kalshi price include fees? No. The cent price is the market's probability; Kalshi charges a separate trading fee on top, and it is largest near coin-flip prices. That fee raises your real break-even above the sticker price, so a 63¢ contract that reads as -170 behaves closer to -186 in practice. See our Kalshi fees guide for the full formula.

Why does a Kalshi contract sometimes settle differently than a moneyline? Because it grades on its own written rules, which can differ from a sportsbook's. A contract can void on a postponement, resolve on a precisely worded condition, or carry a prop cutoff, and details like whether overtime counts are defined per market rather than assumed. Always read the contract's settlement terms before treating its price as interchangeable with a sportsbook number.
