How Do Prediction Markets Work? A Step-by-Step Walkthrough

The short answer

A prediction market turns a real-world question — "Will the Super Eagles win their next match?" — into two tradable sides, YES and NO. The price of each side (between 0 and 1) is the crowd's live probability estimate. When the event resolves, the winning side pays out in full.

That's the concept. Here's how it actually plays out, step by step, the way it works on Tradebanta.

Step 1: A market is created

Every market starts as a question with a clear, verifiable outcome and a settlement source — so there's no ambiguity about who won. On Tradebanta, markets span sports, politics, entertainment, the economy and community debates.

Step 2: Trading opens and a price forms

Early traders take positions, and the price settles where buying and selling balance. If YES opens at 0.50, the crowd is saying 50/50. From that moment, the price is alive — it moves every time someone trades.

Step 3: News moves the price

This is where prediction markets shine. Say the star striker is ruled out injured. Traders react instantly: YES holders sell, NO buyers pile in, and the price drops — maybe from 0.50 to 0.38 — within minutes of the news breaking.

No waiting for pundits or updated polls. Money on the line makes people honest and fast. (More on this in [how market odds change](/blog/how-market-odds-change) and [crowd intelligence explained](/blog/crowd-intelligence-explained).)

Step 4: You take your position

You buy the side you believe in at the current price:

• YES at 0.38 costs ₦0.38 per unit (or $0.38, depending on your wallet)
• If you're right, each unit pays ₦1 — roughly 2.6× your stake
• If you're wrong, the units expire worthless

You always know your exact cost and maximum payout before you confirm. Tradebanta shows the full quote up front.

Step 5: You can exit before settlement

You're never locked in. If you bought YES at 0.38 and positive team news pushes it to 0.60, you can cash out early at the new price and bank the difference — without waiting for the match. Equally, if the price moves against you, cashing out early limits your loss.

Step 6: The event settles

When the outcome is official, the market resolves against its settlement source:

• Winning side: each unit pays 1 (₦1 or $1)
• Losing side: expires at 0
• Winnings land in the wallet you traded from

Step 7: Winnings are yours

Withdraw NGN to your verified Nigerian bank account, or USD via the payout options for your region — or keep trading. Your positions, history and transactions are all in your portfolio.

A quick worked example

| Moment | Price of YES | Your position | |---|---|---| | You buy ₦1,000 of YES | 0.38 | ~2,631 units | | Team news breaks, price rises | 0.60 | Worth ~₦1,578 | | You cash out early | 0.60 | +₦578 profit | | (Alternative: held to settlement, team wins) | 1.00 | ~₦2,631 payout |
