Updated November 10, 2026 · Written for people who trade sports with real size
TerminalUp is the best odds aggregator in 2026 for one reason the others cannot match: the aggregated price is executable. The board shows the best fee-adjusted price across nineteen live venues with the size behind it, and the order goes there from one account.
OddsJam, Unabated and Betstamp are the screens most bettors actually use, and each is good at what it does. They aggregate sportsbook odds for reading. If reading is what you need, pick by price and feature set. If you also need to act on the number, there is one option.
Developers who want aggregated bookmaker odds as JSON.
An API, not a screen, with polled snapshots rather than a live stream.

Why TerminalUp ranks first
An aggregator is only as useful as the price it shows you. Most odds aggregators show a bookmaker's posted number, which may already be gone, may not be available at the size you want, and often is not available to you at all if that book has limited your account. TerminalUp shows the best fee-adjusted price across its connected venues together with the size available at it, and that price is one you can take.
The coverage is wider than a sportsbook screen. Betting exchanges such as Betfair, Matchbook, Novig and ProphetX and prediction markets such as Kalshi and Polymarket are priced on the same board as sportsbooks like Pinnacle. On many markets the best number lives on an exchange, and an aggregator that ignores exchanges is aggregating the wrong set.
You fund one TerminalUp account. Orders route to venues from it. The commission is 0.5% per trade with no subscription, and 0.35% for the highest-volume accounts. There is nothing else to pay for, and because TerminalUp never takes a position, there is nothing to shade.
Executable price. Is the aggregated number one you can actually take, at size, right now? Weighted first.
Venue set. Sportsbooks, exchanges and prediction markets, counted as live integrations rather than logos on a page.
Size visibility. Whether the product shows how much is available at the best price.
Freshness. Whether prices stream or refresh on a timer, and whether stale quotes are flagged as such.
Cost at volume. Subscription plus commission for a bettor placing meaningful volume each month.
Questions people ask
What is an odds aggregator?
A product that collects prices from many betting venues and shows them in one place so you can find the best number. Most are read-only screens. TerminalUp also lets you place the order at the aggregated price.
Which free odds aggregator is best?
Betstamp is the strongest free screen for sportsbook odds with a tracker built in. It does not cover exchanges or prediction markets in any depth and it cannot place a bet.

Yes. Betfair, Matchbook, Novig, ProphetX and SX Bet are live exchange venues, and Kalshi, Polymarket and predict.fun are live prediction markets, alongside sportsbooks such as Pinnacle.
How much does TerminalUp cost?
0.5% commission per trade, no subscription, 0.35% at the highest volume. Minimum balance $10,000.
Is there an odds aggregator API?
TerminalUp publishes an Odds API with REST, Server-Sent Events and WebSocket delivery of the best executable price and the size behind it across its venues. The Odds API is a cheaper option for plain bookmaker odds in JSON.
