The One-Sentence Answer
What prediction markets actually are
A prediction market is a contract that pays $1 if something happens and $0 if it doesn't. If the contract is trading at 72¢, the market is pricing the event at about a 72% chance. You're not betting against a house — you're trading against other people.
$1
Event happens
$0
Doesn't happen
72¢
= 72% probability
The price IS the probability. Buy at 72¢ → profit 28¢ if it happens, lose 72¢ if it doesn't.
How Prediction Markets Work
3 steps to understand the mechanics
Every prediction market follows the same basic pattern. You pick an event, buy contracts at a price that reflects the probability, and collect $1 per contract if you're right.
Pick a market
Choose an upcoming event with a Yes/No outcome — like 'Will the Fed cut rates in June?' Every contract has a deadline and written resolution rules.
Buy shares
Pay 72¢ per share. If the event happens, each share pays $1.00, so your gain is 28¢. If it doesn't, you lose the 72¢ you paid. You choose how many shares to buy.
Collect or lose
When the deadline passes, the contract resolves. Winning shares pay $1. Losing shares pay $0. Platforms may charge a fee depending on the market and platform rules.

Are prediction markets gambling? The honest answer.
How it's like gambling
- ✗You can lose 100% of what you put in
- ✗Platforms charge a fee (like a rake)
- ✗Short-term outcomes are unpredictable
- ✗Addictive dynamics can apply
How it's different
- No house odds — you trade against other people
- CFTC-regulated as commodity futures
- Prices aggregate real information, not RNG
- You can exit a position early (sell your shares)
The law treats prediction markets as commodity futures, not gambling. Your personal opinion may differ — and that's a legitimate position. Full comparison →

Where to Start
3 platforms most beginners choose
Three platforms most beginners start with — each for different reasons:
kalshi
Most variety, full CFTC exchange license
Broad market selection across politics, economics, sports, weather, and culture. A natural starting point if you want a regulated U.S. platform.
Fees: Formula-based taker fee on entry
polymarket
Highest volume on elections and macro events
Often where traders concentrate around elections and macro events. It uses USDC, so access and onboarding differ by state and product.
Fees: Probability-based taker fees across most categories. Dynamic rates peak at 50% probability.
robinhood
Easiest onboarding if you already have the app
Kalshi-powered markets inside the Robinhood app. If you already use Robinhood, it's usually the simplest place to try a first trade.
Fees: $0.01 Robinhood commission + $0.01 Kalshi exchange fee = $0.02 total per contract per side
