What is OVERDOG?
Browse match winners, handicaps, totals and props by event, with league navigation and in-play scores. Odds can be shown as decimal, American, fractional or probability values. The terminal routes to Polymarket liquidity rather than operating a separate sports exchange, and available order-book depth still constrains fill size and price.
The provider states that it holds the account key, making this a custodial interface. Fills remain public on-chain and can be inspected through links in the activity feed. Combo terms need their own review: a quoted combination should not be assumed equivalent to holding all legs independently. Platform and venue fees also sit beyond a reading of the odds alone.
