Kalshi And American Odds: Why The Price Is In Cents
You speak American odds. You know -110 without thinking, you know +260 is a live long shot, and you know which of the two you would rather be holding when the game ends. Then you open Kalshi and the board offers you a number like 62¢, and none of that fluency helps. This page fixes that in about five minutes: what a cents price is, how it converts to the odds you already read, and the two places the conversion quietly stops working. It also covers a piece of news worth knowing before you bother memorizing any toggle: the federal regulator that oversees these exchanges has, by Bloomberg's reporting, warned the industry away from American-style odds displays. That story sits near the end, in its proper size, because the arithmetic comes first and outlasts it.
The Quick Answer
Kalshi's native quote is not a moneyline. Every contract is priced in cents, from 1¢ to 99¢, and the price is the market's break-even probability: a 62¢ contract needs to win about 62% of the time to break even before fees, which converts to roughly -163 in American odds. Below 50¢ converts to positive odds, above 50¢ converts to negative odds, and 50¢ is even money. The full conversion, worked in both directions, the two places the translation breaks, and what the CFTC's warning about American-style odds did and did not say are all below.
A Cents Price Is A Break-Even Probability
Start with what the number physically is. A Kalshi contract settles at exactly $1 if the event happens and $0 if it does not. Buy the Yes at 62¢ and you are risking 62 cents to collect a dollar. That only works out if the event happens more than 62% of the time, so the price you pay is the probability you need. No plus sign, no minus sign, no payout ratio to unwind: the cost and the required win rate are the same number, quoted before fees.
The other side of the same contract completes the picture. If Yes trades at 62¢, No trades at roughly 38¢, and the two sides of the book sum to about a dollar. A sportsbook never shows you a number this naked; its two sides sum to more than 100% because the margin lives inside the line. That structural difference is the real subject of an exchange is not a sportsbook, and it is why the cents format is not a quirk. It is the underlying probability with no costume on. Whether the crowd's probability is a good estimate is a separate question, and a 30-cent contract does not mean 30%, or does it takes that one on.
So the translation you came for is real, but understand what you are translating: American odds are a payout format, cents are a probability format, and the conversion is just moving one fact between two notations.
The Conversion: Cents To American Odds
Two rules cover the whole board, split at the 50¢ line:
- Below 50¢, The Contract Is An Underdog And Converts To Positive Odds: American = (100 − price) ÷ price × 100.
- Above 50¢, The Contract Is A Favorite And Converts To Negative Odds: American = −(price ÷ (100 − price)) × 100.
Every number below is a round, illustrative figure for learning the math, not a live price from any market.
| Price In Cents | Break-even probability | American odds |
|---|---|---|
| 10¢ | 10% | +900 |
| 25¢ | 25% | +300 |
| 38¢ | 38% | +163 |
| 50¢ | 50% | +100 (even money) |
| 62¢ | 62% | -163 |
| 75¢ | 75% | -300 |
| 90¢ | 90% | -900 |
Look at the 62¢ and 38¢ rows together, because they are the same row wearing opposite signs. A 62¢ favorite is -163; the 38¢ contract on the other side of the same market is +163. Every price above 50¢ has a mirror below it carrying the same American number with the sign flipped, so once you can read one half of the board you can read all of it. The 50¢ row is the hinge: American odds flip their sign there, jumping from +100 to about -104 on a one-cent move, while the cents just tick from 50 to 51. Nothing about the contract changed. Only the notation did.
Worked Example: -110 And +260, Turned Into Cents
Going the other direction is the more useful skill, because it lets you hold a sportsbook line next to an exchange price. Two steps, using the odds number without its sign:
- A Favorite At -X: cents = X ÷ (X + 100) × 100. The -110 you have seen a thousand times works out to 110 ÷ 210, about 52¢.
- An Underdog At +Y: cents = 100 ÷ (Y + 100) × 100. A +260 long shot works out to 100 ÷ 360, about 28¢.
That -110 result is worth sitting with. Standard sportsbook juice, translated into this format, means paying about 52¢ for a coin flip that is honestly worth 50¢. The cents format shows you the cost of the line the moment you convert it, which is precisely the thing the American format is good at hiding. One caution, though: converting a book's line gives you the book's asking price, not a clean probability, because the margin is still inside it. Stripping that out is its own small skill, and our de-vig walkthrough for exchange traders does the arithmetic step by step.
The Two Places The Translation Breaks
Here is the part a converter widget will not tell you, and the reason to learn the format instead of outsourcing it. The conversion above is exact as arithmetic and incomplete as a description of the bet.
First, fees. A cents price is your break-even before Kalshi's trading fee. The fee is charged on top of the price and is largest near coin-flip prices, so a contract you buy at 62¢ needs slightly more than 62% to profit once you have paid to get in. The sticker converts to -163; your effective entry behaves a little worse than that. The full fee curve lives in how Kalshi's fees work, and the one-line version is that the screen price is a floor on your true cost, not the whole of it.
Second, settlement. A contract that looks like a moneyline does not always settle like one. A Kalshi contract grades on its own written rules against a named source: a temperature contract settles on one specific weather station's reading, not on what your phone's weather app says the city hit, and an event contract can void, resolve, or cut off on conditions a sportsbook version of the same bet would treat differently. The conversion tells you the price is equivalent; it cannot tell you the bet is. Read the market's rules before treating its price as interchangeable with a book's line, and see what actually happens when a contract settles for how grading works. For the fuller version of all of this, the full guide to reading a Kalshi price is the companion page: this one makes you conversational, that one makes you fluent.
Those two breaks are also the honest answer to why this page exists at all. A calculator can do the division. It cannot tell you when the division stops describing the trade.
The CFTC Warning: What Was Said, And What Was Not
Now the news, at exactly the size the sourcing supports. Bloomberg, in a story by Nicola M White and Lydia Beyoud headlined "CFTC Warns Prediction Markets Against American-Style Casino Odds," reported that the Commodity Futures Trading Commission told prediction markets to avoid using American-style gambling odds as the regulator fends off legal challenges alleging the platforms are illicit sports betting operations. Per the same reporting, the agency sent a warning to CFTC-regulated entities reminding firms they need to comply with US laws governing derivative trades and not use "deceptive" practices to list, solicit or advertise the products, according to a letter viewed by Bloomberg.
The verbs are the story: warns, avoid, reminding. This is a warning letter, and a warning letter is a different thing from a ban, a rule, or an enforcement action. The letter itself is not public, and the CFTC has published nothing about it, so everything known about its contents is Bloomberg's characterization of a document Bloomberg has seen. You may also run into posts claiming a hard deadline for American odds to disappear. No deadline appears in Bloomberg's reporting and we could not verify one anywhere, so treat any specific date you see as unconfirmed until a CFTC document or a second outlet prints one.
And the detail most coverage will get wrong: the letter went to CFTC-regulated entities, meaning the exchanges and brokers. It governs how they display and advertise their own contracts. It is not a rule about how a reader may think about a price, and it does not make converting a price into odds improper for you or anyone else. The math on this page was never the regulator's concern. What Kalshi or any other venue actually does with its displays next is something we have not observed and will not narrate; the warning is the story, and the warning is where the story ends.
What This Means For You: Learn The Native Number
Our view, stated directly: the cents price is the format to learn, not a quirk to translate away. It was already the better number, because it hands you the probability and the cost in one figure, and the regulatory pressure now points the industry toward it rather than away from it. The 62¢ from the top of this page is the durable version of that fact; the -163 was always a translation for visitors. If American-style displays become scarcer on regulated venues, a reader who owns the conversion loses nothing, and a reader who depended on the toggle loses their bearings. Five minutes with the table above is the difference.
None of that changes what these instruments are. Kalshi is a CFTC-regulated exchange and its contracts are event derivatives with broad, state-specific availability under federal oversight. Whether trading them is closer to investing or wagering is a fair fight we take up in is trading on Kalshi gambling.
The Shape Of The Risk Behind The Price
One more thing the cents format makes visible that American odds tend to bury. Selling an unlikely outcome, which is what you are doing whenever you hold the expensive side of a lopsided market, collects a small premium while risking most of a dollar. Roughly speaking, one loss erases the premiums from about 14 wins. That asymmetry, not any hit rate, is what makes position sizing the entire game in event markets. We say this from the inside: Stokastic trades these markets and holds positions in them, and where a settled position is described anywhere on this site, we were the seller. Our open log of how these markets work is a record of a strategy we are not yet claiming works, kept public on purpose.
Kalshi American Odds FAQ
What does 62 cents mean on Kalshi? You pay 62¢ for a contract that returns $1 if the event happens, so the market is pricing the event at about a 62% chance, roughly -163 in American odds. The practitioner's footnote: that 62% is your break-even before Kalshi's trading fee, which is largest near coin-flip prices, so a 62¢ fill behaves a little worse than the -163 sticker once you have paid to get in.
How do I convert Kalshi odds to a moneyline? Split at 50¢. Below it: (100 − price) ÷ price × 100 gives positive odds, so 25¢ becomes +300. Above it: −(price ÷ (100 − price)) × 100 gives negative odds, so 75¢ becomes -300. Exactly 50¢ is even money.
Is there a Kalshi odds calculator? The two rules above are the whole calculator, and they run in your head with round numbers. For a longer conversion chart and more worked examples, our full guide to reading a Kalshi price, linked above, covers the rest of the board.
Does Kalshi have moneylines? The native quote is cents, and any American-odds number a venue's screen renders is a translation of that cents price, not a separate market. A moneyline is a payout ratio; a Kalshi price is a probability; the conversion rules on this page move between the two, so you are never dependent on how any screen chooses to dress the number.
Are Kalshi odds better than sportsbook odds? They are different instruments rather than better or worse ones. An exchange price has no margin inside it but adds a trading fee on top, and its contract can settle on different rules than a book's version of the same bet. Comparing honestly means converting both to probabilities, adding the fee, and de-vigging the book's side first.
Did the CFTC ban American odds on prediction markets? No. By Bloomberg's reporting, the CFTC sent a warning letter telling regulated prediction markets to avoid American-style gambling odds and reminding them not to use "deceptive" practices in listing or advertising contracts. A warning is not a ban, the letter is not public, and no verified deadline for any change exists.
The Price Was Never The Costume
Zoom back out. American odds dress a probability up as a payout; Kalshi prints the probability itself. Learning to read 62¢ without converting it is not homework the regulator assigned you, it is the shorter path to understanding what every betting number was trying to say all along.

Disclosure and fine print. Stokastic trades Kalshi weather markets and holds positions in them; where a settled position is described, we were the seller. We have no affiliate or commercial relationship with Kalshi. We do carry sign-up offers for some other prediction-market and betting platforms, and pages naming those platforms should be read with that incentive in mind. Kalshi contracts are CFTC-regulated event derivatives traded on a designated contract market, not sportsbook wagers, and a position can lose its full value; selling an unlikely outcome collects a small premium and risks most of a dollar, and one losing sale can hand back the premiums from about 14 winning ones. 18+, available where Kalshi operates; eligibility and availability are state-specific and change. Nothing on this page is trading advice, a pick, a play, or a recommendation to enter any market, and no price shown here is a live quote.
