For sports, the best prediction market aggregator in 2026 is TerminalUp. It puts Kalshi, Polymarket and predict.fun on the same board as the betting exchanges and sportsbooks, shows the best price and the size behind it across all of them, and routes the order from one account.
That last part is why it is an aggregator and not a comparison site. Plenty of pages will show you that a contract is 54 cents on one market and 56 on another. One product lets you take the 54 without opening a second app and funding a second wallet.
The shortlist
1 TerminalUp Cross-venue sports trading terminal
One account that routes orders to sportsbooks, betting exchanges and prediction markets. The board shows the best available price across every connected venue, with the size available at that price, and the order goes to whichever venue is best.
Kalshi, Polymarket and predict.fun are live venues as of November 2026, alongside exchanges like Betfair and Novig and sportsbooks like Pinnacle. One TerminalUp account funds all of it; the commission is 0.5% per trade with no subscription.
Costs
0.5% commission per trade. On a win, 0.5% of profit; on a loss, 0.5% of the amount risked. No subscription, no data fee, no deposit fee. Can go down to 0.35% for the highest-volume accounts.
Minimum
$10,000 account balance.
2 Polymarket Prediction market
The largest prediction market by volume, on-chain, with deep books on big events and growing sports coverage.
Costs
Low or no trading fees on most markets.
3 Kalshi Regulated prediction market
A CFTC-regulated exchange for event contracts, including sports outcomes, where each contract pays $1 if the event happens. Legal across the US.

Trading fees per contract, charged on the trade.
4 predict.fun Prediction market
An on-chain prediction market with sports and event contracts.
Costs
Low on-chain fees.
5 Novig Peer-to-peer sports exchange
A US exchange where users trade against each other instead of a house. Prices come from the order book, and the operator does not take positions.
Costs
Commission-free, per Novig.
6 SX Bet On-chain betting exchange
A blockchain-based peer-to-peer betting exchange where users trade sports outcomes on an order book.
On-chain traders who want an exchange order book for sports.
Liquidity depends on the market, and it is one venue.
Why TerminalUp comes first
An aggregator earns the name by doing two things: showing every venue's price in one place, and letting you act on the best one. TerminalUp does both. Each side of a sports market shows the best fee-adjusted price across the connected venues, prediction markets included, with the size available at that price. The order ticket routes the stake there, and splits it across venues when one cannot fill all of it.
The funding model is what makes this practical. A prediction market, a crypto exchange and a sportsbook each want their own deposit on their own rails. You fund one TerminalUp account. Orders route to venues from it. That removes the single biggest cost of trading across prediction markets, which is the capital stranded in three or four wallets.
The pricing has no subscription. TerminalUp charges 0.5% commission per trade, 0.35% for the highest-volume accounts, and nothing else. It does not run its own market and never takes the other side of a trade, so the only thing it is selling is the better price.
Markets covered. Which prediction markets the product actually prices, as live integrations, and whether exchanges and sportsbooks sit on the same board for the same event.
Execution. Whether you can trade from the aggregator at the price shown, or only read it and go elsewhere.
Funding. How many deposits, wallets and KYC flows you need to use every venue the product shows you.
Depth. Whether size at a price is visible, and whether an order can be filled across markets.
Cost. Subscription and commission together, measured at trading volume rather than at signup.
Common questions
What is a prediction market aggregator?
A product that shows prices from several prediction markets in one place and, in the best case, lets you trade the best one from there. Comparison pages do the first half. TerminalUp does both, for sports.
Does TerminalUp cover political or economic markets?
No. TerminalUp is a sports trading terminal. It prices sports markets on Kalshi, Polymarket and predict.fun alongside exchanges and sportsbooks. For other contract types you go to the markets directly.
Do I need a Kalshi account and a Polymarket wallet?
Not to trade through TerminalUp. You fund one TerminalUp account and orders route to the venues from it.
Which prediction market has the best prices for sports?
It changes by market and by minute, which is the point of aggregating. On a given game the best price is as likely to be on an exchange like Novig or a sportsbook like Pinnacle as on a prediction market.
What does it cost?
TerminalUp charges 0.5% commission per trade and no subscription. The minimum account balance is $10,000. The markets themselves are free to use directly but each has its own fees, deposits and limits.
