Trade Polymarket like a professional desk.
Oddsterm is a desktop-first trading terminal for Polymarket: a full depth-of-market ladder, live underlying feeds next to every market, and pro order tools — one-click quoting, instant exits, capital-efficient merges — on a non-custodial wallet with silent signing.
Every tick. One click.
A real depth-of-market: tick-by-tick price grid, join or take with one click, post-only quoting, drag your resting orders to a new level, exit the whole position at any P/L level you click. Auto-center off and you own the ladder — the market never moves your target.
Watch the number that settles the market.
BTC five-minute windows, daily indices — the underlying price streams right next to the odds, with the open/strike line, distance and velocity, and a live verdict. No second screen, no other tab.
Reward programs become a workflow.
The reward band is drawn on the book — every order shows if it’s earning, too small, or out of band. Hold both sides? Merge YES+NO pairs in one gas-free click — or automatically above your threshold — and free the capital.
Your keys, silent signing.
Log in with email or wallet: a non-custodial trading wallet is set up automatically. Orders are signed in the background — no popups, no extension — deposits and withdrawals run gas-free. Funds and keys stay yours.
Email, passkey or your own wallet. A non-custodial trading wallet is created for you in seconds.
Card, external wallet or exchange transfer. Arrivals are converted and credited automatically, gas-free.
Pick a market, click the ladder. Positions, fills and P/L update live; exit with one click.
▸▾Is Oddsterm affiliated with Polymarket?
No. Oddsterm is an independent interface built on Polymarket through the official Builders Program. All markets, order matching and settlement happen on Polymarket’s protocol.
▸▾Does Oddsterm hold my funds?
No. Your trading wallet is non-custodial: keys are controlled by you (via your login), funds sit in your wallet on Polygon, and you can withdraw at any time. Oddsterm never has custody.
▸▾What does it cost?
Oddsterm is free to use. Orders placed through Oddsterm carry our builder code, which attributes the volume to us under Polymarket’s Builders Program. You pay nothing extra versus trading on Polymarket directly.
▸▾Where do my orders go?
Straight to Polymarket’s CLOB, signed by your wallet. Oddsterm is an interface: it doesn’t route, internalize or touch your orders.
▸▾Can I use it everywhere?
Polymarket enforces regional restrictions at the protocol level, and Oddsterm applies the same policy in the interface. In restricted regions trading is limited or unavailable.
▸▾Mobile or desktop?
Both work — but Oddsterm is desktop-first. The full toolkit (DOM ladder, drag orders, P/L exits) lives on desktop; mobile covers monitoring and quick orders.
