What Is a Sports Prediction Exchange? How Trading on Pred Works
TL;DR: A sports prediction exchange is a marketplace where traders buy and sell contracts on sports outcomes directly with each other, through a shared order book, instead of placing a wager against a bookmaker. Each contract is priced between one cent and 99 cents, its implied probability, and pays one dollar if the outcome happens and nothing if it does not. Pred is a sports prediction exchange built on Base, Coinbase's Ethereum Layer 2, with balances held in USDC. No house sits on the other side of your trade, so the price comes from other traders, and a trader who keeps winning is never a problem the venue has to manage.
Picture one contract: the home side to win, trading at 62 cents. Buy it and you have paid 62 cents for something worth a dollar if they win and nothing if they lose. The 62 cents is the market's read on their chances, roughly a 62% probability. If they score early and the price climbs to 78 cents, you can sell and pocket the 16-cent move without waiting for full time.
You are not backing a number a bookmaker handed you. You are trading a price with other people who read the match differently, and that price moves as they change their minds.
This page covers the category, the contract, and a trade from start to finish. The head-to-head with sportsbooks, live in-play trading, and funding an account each have their own page, linked below.
What is a sports prediction exchange?
A sports prediction exchange matches two traders who take opposite sides of the same contract. One buys the home side to win; another sells it. The exchange pairs them and takes a small fee on the match. It never picks a side of its own.
That is a different machine from the one most fans know. A bookmaker sets the price, takes the other side of every wager, and earns the margin baked into the odds. It is the shop, the seller, and your counterparty at once. An exchange is the other arrangement: a market full of buyers and sellers, where the price is whatever two of them agree on.
One thing follows directly from that structure. Because no house holds the opposite position, an exchange has no reason to limit or ban traders who win. That holds for the exchange model as a category, not as a favour any one platform grants.
What does a contract's price mean, and how does it settle?
On Pred, the price of a contract is its implied probability. Each contract trades on a scale from one cent to 99 cents, and the price reflects what the market believes the outcome's likelihood to be. A contract at 60 cents is the market putting the chance at about 60%.
Settlement is binary. If the outcome happens, the contract is worth one dollar. If it does not, it is worth nothing. The most you can lose on a position is what you paid to open it.
You do not have to hold a contract to the end. A position can be bought and sold any number of times before the event finishes, so you can enter when a price looks wrong and close once it has moved. This is where resolution speed earns its keep: most markets resolve in about three minutes, so a trader who reads an early goal correctly can collect and move on while the match is still being played.
How does trading on Pred work?
Pred is a peer-to-peer sports prediction exchange. Every trade pairs one trader against another, balances are held in USDC, and the order book runs on Base.
Three numbers describe the experience, and Pred holds each as a standing feature:
· Execution in 200 milliseconds. Your order is matched faster than a live price can drift away from you.
· Resolution in about three minutes. Once a result is known, the market settles in minutes rather than hours.
· Spreads under 2%. The gap between the buy price and the sell price stays tight.
A trade follows a short loop. Fund an account in USDC, open the market for a match, and read the contracts and their live prices on one screen. Pick the side you want, confirm the position, then hold it or sell before the market settles.
The trading screen is built to feel like a sportsbook you already know, with the exchange working underneath rather than a house setting the line.
How is a sports prediction exchange different from a sportsbook?
One difference does most of the work: who sits on the other side of your trade.
A bookmaker profits when its customers lose, so it has every reason to watch a customer who wins too often. An exchange earns the same fee whether you win or lose, because your money is paid by another trader, not by the house. On an exchange, a sharp trader is not a liability to manage. There is no house for them to beat.
Why does Pred run on Base?
Pred runs on Base for low-cost, on-chain transactions at the speed live sport demands. Base is an Ethereum Layer 2 network built by Coinbase, described in Coinbase's launch announcement as a secure, low-cost, developer-friendly way to transact on-chain, secured by Ethereum and built on the open-source OP Stack.
For a trader, the practical effect is that the order book and the settlement sit on-chain rather than inside a closed system, so they can be verified rather than taken on trust. Base carries the settlement layer; Pred's order book handles the matching, which is what keeps execution under 200 milliseconds.
Why are sports prediction exchanges growing now?
Combined monthly volume on the two largest prediction markets rose from under 5 billion dollars in September 2025 to about 24 billion dollars in April 2026, according to a Pew Research Center analysis of data from The Block. Sport is the engine of that growth: on one of those two venues, sports contracts have made up about 80% of volume since July 2024.
Sport carries traits no other category shares. Volume concentrates on match day and during live play, outcomes are settled by clear governing-body results, and a single match can support a long run of related markets. Those traits are why a sports-built venue like Pred is shaped around live engagement and a high number of markets per fixture, rather than the future-dated questions that drive general prediction markets.
Sports prediction exchange vs sportsbook vs general prediction market
The three ways most people take a position on sport differ in who sets the price, who you face, and what the venue is built for.
| Sports prediction exchange | Traditional sportsbook | |
|---|---|---|
| Who sets the price | Other traders, through an order book | The house, with a margin built in |
| Who you trade against | Another trader with the opposite view | The house |
| If you keep winning | Nothing changes; no house to protect | Account can be limited or closed |
| What it is built for | Live, in-play sport; many markets per match | A broad catalogue across many sports |
| How a position resolves | Settles at one dollar or nothing | Pays the posted odds |
A sports prediction exchange and a general prediction market share the same machinery, an order book and binary contracts. The difference is focus: a sports-built exchange is shaped around live play and the dense set of markets a single fixture throws off, where a general market spreads itself across every topic in the world.
There is an honest trade-off worth naming. A newer, sports-focused exchange is still building its order books, so the very largest positions may not always find the depth available on long-established general venues. For most traders this never comes up, and depth grows as more traders arrive.
Frequently asked questions
What is a sports prediction exchange? It is a marketplace where two traders take opposite sides of a contract on a sports outcome, instead of wagering against a house. The venue matches the trades and earns a fee, so it has no stake in who wins. Each contract pays a dollar if the outcome happens and nothing if it does not.
Is Pred a betting exchange? Pred is a sports prediction exchange. The instrument is the difference: on Pred you buy and sell a contract that settles at a dollar or nothing, and you can sell out of it before the result is known. A wager with a bookmaker is a single stake at fixed odds you cannot trade.
Can you sell a position before the match ends? Yes. A position trades at a live price, so you can close it before the event resolves. On Pred, a position can be bought and sold any number of times before the event finishes. A contract bought at 40 cents that climbs to 65 cents can be sold for the difference, rather than held to see whether it lands at a dollar or nothing.
How fast does Pred settle a trade? Pred executes a trade in under 200 milliseconds and resolves most markets in about three minutes. Fast execution means you get the price you saw rather than one that has already moved. Fast resolution means a winning position is back in your balance in minutes, ready to redeploy while the match is still on.
Do you need crypto experience to start on Pred? You need access to USDC, the stablecoin Pred uses for positions, but not a background in crypto. Trades and settlement run on Base underneath, while the screen is built to feel like a sportsbook you have used before. The full walkthrough is on the funding guide.
