Polymarket supports 8 different odds formats. If you’re used to seeing American odds, decimal odds, or fractional odds from traditional sportsbooks, you can switch Polymarket’s display to match the format you’re comfortable with. The setting takes about 5 seconds to change and applies across the platform.
This recently changed. The odds-format setting used to be limited to sports markets. It now lives in Polymarket’s Settings section and is available more broadly — so non-sports traders can use decimal, American or fractional display too.
Step-by-Step: Changing Your Odds Format
Step 1: Open Polymarket Settings
Open Polymarket and go to the Settings section. This is where the odds display preference lives — it is no longer a per-market toggle on sports pages.
Step 2: Find the Odds Display Setting
In Settings, locate the odds display / format option. Click it to see the list of available formats.
Step 3: Choose Your Format
Pick from the eight available formats below. The change applies immediately.
Step 4: Choose Your Preferred Format
Select from any of the 8 available formats:
- Price
- American
- Decimal
- Fractional
- Percentage
- Indonesian
- Hong Kong
- Malaysian
Your selection takes effect immediately. The odds displayed across the market page will update to reflect your chosen format.
Note: Your selection persists across markets and future sessions. You only need to set it once, and every market you visit will display odds in your chosen format.
Available Odds Formats
Here’s how each format displays the same probability — using an outcome priced at $0.65 (65% implied probability) as an example:
Price (Default)
Display: $0.65
Polymarket’s native format. Each outcome is shown as a dollar value between $0.00 and $1.00. The price directly represents the cost per share and the implied probability. A price of $0.65 means you pay 65 cents per share and win $1.00 if the outcome is correct.
American
Display: -186
The standard format used by American sportsbooks. Negative numbers indicate favorites — the number tells you how much you’d need to risk to profit $100. In this case, -186 means risking $186 to profit $100. Underdogs show positive numbers (e.g., +186 means a $100 bet profits $186).
Decimal
Display: 1.54
Popular in Europe, Australia, and Canada. The decimal number represents the total return per dollar wagered, including your stake. At 1.54, a $1 share returns $1.54 total ($0.54 profit + $1.00 stake). Lower numbers mean stronger favorites.
Fractional
Display: 7/13
The traditional format used by UK bookmakers. The fraction represents profit relative to stake. At 7/13, you profit $7 for every $13 risked. Fractional odds below 1/1 (like 7/13) indicate a favorite.
Percentage
Display: 65%
The simplest format — the implied probability shown as a percentage. At 65%, the market estimates a 65% chance of this outcome occurring. This is identical to the Price format but expressed as a percentage instead of a dollar amount.
Indonesian
Display: -1.86
Common in Southeast Asian markets. Works similarly to American odds but scaled to a base of 1 instead of 100. A value of -1.86 means risking $1.86 to profit $1.00. Positive values indicate underdogs.
Hong Kong
Display: 0.54
Used in Hong Kong betting markets. Shows the net profit per unit staked. At 0.54, a $1 share returns $0.54 in profit (plus your $1 stake back). Similar to decimal odds minus 1.
Malaysian
Display: -1.86
Used in Malaysian betting markets. For favorites (negative values), -1.86 means risking $1.86 to profit $1.00 — identical to Indonesian odds for favorites. For underdogs, Malaysian odds show as a positive decimal representing profit per $1 staked.
Which Format Should I Use?
The best format depends on what you’re already familiar with:
- New to trading and betting? Stick with Price or Percentage. These are the most intuitive — you see the probability directly without needing to calculate anything.
- Used to American-style lines? Switch to American. If you’re used to seeing -110 lines and +200 underdogs at a sportsbook, this will feel natural.
- European or Australian bettor? Use Decimal. It’s what you see on Bet365, Betfair, and most international sportsbooks.
- UK bettor? Use Fractional. Classic format from William Hill, Ladbrokes, and UK racing.
- Asian market bettor? Choose Indonesian, Hong Kong, or Malaysian depending on which platforms you use.
- Experienced Polymarket trader? Most regular users prefer Price since it directly maps to the platform’s share pricing system. You always know exactly what you’re paying per share.
There’s no wrong answer — the format is purely a display preference and doesn’t affect how trades execute or what you pay.
Scope: Broader Than Sports Now
The odds format setting used to be exclusive to sports markets — basketball, football, baseball, hockey, soccer, tennis, MMA and the rest. That restriction has been relaxed, and the setting is now reached through Settings rather than a per-market gear icon, applying more widely across the platform.
Odds formats like American (-110) and decimal (1.91) come from the sports betting world, so they were originally scoped to sports. Non-sports traders have historically had to read prices in the native Price format.
Whatever the display, the underlying price is the same. The price of a share equals its implied probability — a Yes share at $0.70 means the market thinks there’s a 70% chance of that outcome. Read our understanding odds guide for a deeper explanation.
Scope: this article covers the international exchange, which is the platform this site covers throughout. The separate, CFTC-regulated US app has a much simpler display toggle — just price (¢) or percent chance (%) — so the eight formats below are international-exchange only.
