Overdog is a betting terminal wired straight into Polymarket's order book, covering 19 sports and 12 esports. The price on screen is the one traders are actually dealing at, both sides of a market add up to 100%, and no one sits on the other side with a reason to limit a winner. Odds render in decimal, American, fractional, or probability, and any position can be sold back before the whistle.

The board is broken out by competition and league, with a Live tab for every in-play game, scores and clocks running, and prices ticking over a websocket as the book moves. Combos build multi-leg tickets across markets. The order-book ladder shows real depth before anything is staked, and orders can be rested instead of taken: a limit buy waits below the ask, a limit sell doubles as a take profit, and a stop caps the downside. Any position sells back into the book, in full or in part, right up to resolution.

Pricing is one line: a flat 1% to Overdog plus Polymarket's exchange fee, identical whether a bet wins or loses, which puts the all-in cost near 1% of stake for makers. An account is a Google or Telegram sign in and an 18+ tick, with no documents at any stage, withdrawals included. Deposits are crypto, including BTC, ETH, SOL, USDT, USDC, and BNB, all converting to a dollar unit on Polygon so an overnight coin dump cannot touch a settled bet. Minimum stake is $2, withdrawals have no hold or approval queue, and every fill and payout lands on Polygon as a public transaction. Overdog runs on the web at overdog.bet and as a Telegram bot and mini app, in English, Spanish, Portuguese, and Russian.
