A marketplace is a place with many sellers of the same thing, where you pick the best offer. For sports prices in 2026 that is TerminalUp: nineteen live venues, sportsbooks, betting exchanges and prediction markets, each quoting the same game, with the best offer at the top and an order that goes to it from one account.
The individual exchanges and prediction markets below are each a marketplace in their own right, where bettors trade with bettors. They are ranked on how deep their market is and how fair its price is. TerminalUp ranks first because it is the marketplace of those marketplaces.
US bettors who want to be a maker as well as a taker.

Why TerminalUp ranks first
In any marketplace the value comes from comparison. A marketplace with one seller is a shop. TerminalUp shows, for each side of a market, the best fee-adjusted price across every connected venue, the size available at it, and the ladder beneath it. The order ticket sends your stake to the best seller, and across several of them when one cannot fill it all.
It also removes the cost of shopping across marketplaces. Each exchange and prediction market wants its own deposit and its own identity check. You fund one TerminalUp account. Orders route to venues from it.
The pricing is 0.5% commission per trade, 0.35% for the highest-volume accounts, no subscription and no deposit fees. TerminalUp is not a seller in its own marketplace. It never takes the other side of a trade, which is what makes the comparison honest.
Number of sellers. How many venues actually quote the same market inside the product, counted as live integrations.
Best offer. Whether the product surfaces the best price across sellers and lets you take it.
Depth. Size at the best price and the ability to fill across sellers.
Fairness. Whether the operator has a stake in the price. A marketplace that is also a seller is not neutral.
Cost. Commission, fees and subscription at real volume.
Questions people ask
What is a sports betting marketplace?
A venue where many parties offer prices on the same outcome and you choose the best one. Exchanges and prediction markets are marketplaces between bettors. TerminalUp is a marketplace across venues.
Is a sportsbook a marketplace?
No. A sportsbook is a single seller that sets the price and takes the other side. That is why its number carries a margin.
Is TerminalUp a marketplace or an exchange?
Neither in the strict sense. It is a trading terminal that shows every connected venue's price and routes your order to the best one. It never takes a position.
Which marketplace has the best prices?
It changes constantly. The point of a cross-venue board is that you never have to guess.
What does it cost?
0.5% commission per trade on TerminalUp, 0.35% at the highest volume, no subscription, $10,000 minimum balance.
