Polymarket sports markets support 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 all sports markets.
Step-by-Step: Changing Your Odds Format
Step 1: Navigate to Any Sports Market
Open Polymarket and navigate to any sports market — NBA, NFL, MLB, soccer, or any other sport. The odds format toggle is only available on sports market pages.
Step 2: Click the Settings Icon
Look for the gear/settings icon in the top-right corner of the market page. Click it to open the settings dropdown.
Step 3: Select “Odds Format”
In the dropdown menu, find the Odds Format option. Click it to see the list of available formats.
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 all sports markets and future sessions. You only need to set it once, and every sports 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 $0.01 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 US 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.
- US sports bettor? Switch to American. If you’re used to seeing -110 lines and +200 underdogs from DraftKings, FanDuel, or other US sportsbooks, 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.
Important: Sports Markets Only
The odds format toggle is exclusively available on sports markets. This includes NBA, NFL, MLB, NHL, soccer, tennis, MMA, and other sporting events listed on Polymarket.
Non-sports markets — politics, crypto, economics, weather, culture, and others — always display prices in the default Price format ($0.01 to $1.00). There is no option to change the display format on these markets.
This makes sense: odds formats like American (-110) and decimal (1.91) come from the sports betting world. For non-sports prediction markets, the Price format is the standard.
If you’re primarily trading non-sports markets, understanding the Price format is essential. 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.
