What makes OG different?
OG is a prediction market exchange, rather than a traditional sportsbook. Instead of trading against an operator that sets the odds with a built-in margin, you trade contracts directly with other users.
When you buy Yes, another market participant is taking the No side. This ensures:
Market-driven pricing: Prices are determined by real-time supply and demand between buyers and sellers
Transparent fees: OG charges a clear, flat fee, separating the cost of the trade from the contract price itself
How are contracts priced?
Traditional sportsbooks use various odds systems to set prices. OG contracts use a probability-based model where every contract is priced between $0.01 and $1.00.
This price directly reflects the market's collective estimate of how likely an outcome is to happen. For example:
$0.85 Yes contract means the market estimates an 85% chance the outcome happens
$0.15 No contract means the market estimates a 15% chance the outcome does not happen
Because one outcome must happen, the Yes and No prices in any given market will always total approximately $1.00. See the Contract Price FAQ for details.
Important Note:
Platform fees may cause the total to sit slightly above or below $1.00, but each contract price still directly reflects the percentage chance of that outcome happening.
If you prefer traditional sports layouts, you can switch your display preference from Probability View to American Odds by going to:
From the betslip (Quickest): Gear icon → Betslip settings → Odds format → American
From the main Settings page: Menu → Settings → Odds format → American
From an event page: Gear icon (top right) → Odds format → American
Changing this only updates how the price looks — the underlying contract value remains the same.
How is trading different?
Traditional sportsbooks typically lock in your position until the event ends. OG allows you to sell your position at any time, provided there is a buyer (liquidity) on the other side. This allows you to:
Lock in a profit: Sell your contract early if the market moves in your favor before an event ends
Cut a loss early: Exit your position to minimize a loss when conditions change
Manage exposure: Reallocate your capital across multiple open positions in real time
See the Closing a Position FAQ for details.
Does OG restrict winners?
Traditional sportsbooks routinely limit, restrict, or close accounts that show consistent profitability.
Since OG operates as a marketplace platform that connects buyers and sellers, accounts are never limited or restricted based on trading performance.
