What Is an Event Contract?
An event contract is a simple financial instrument tied to a yes-or-no question about something that will happen in the real world. Will the Federal Reserve cut interest rates before September? Will it rain more than 2 inches in Miami this weekend? Will a specific team win the World Series?
Each contract has two sides: Yes and No. If you believe the event will happen, you buy Yes. If you believe it will not, you buy No. When the event resolves, the winning side receives $1.00 per contract, and the losing side receives nothing.
This binary structure makes event contracts easy to understand. There is no point spread, no moneyline conversion, and no complicated parlay math. You are simply answering a question and putting money behind your answer. The price you pay is your maximum risk, and the difference between your purchase price and $1.00 is your maximum profit.
Example: A contract asks "Will GDP growth exceed 3% in Q3 2026?" You buy Yes at 40 cents. If GDP growth comes in above 3%, your contract pays $1.00 — a 60-cent profit on a 40-cent investment (150% return). If growth is 3% or below, you lose your 40 cents.
How Pricing and Probability Work
Every event contract trades at a price between 1 cent and 99 cents. This price directly represents the market's implied probability that the event will occur. A contract priced at 72 cents means traders collectively believe there is a 72% chance the event happens.
The Yes price and the No price always add up to approximately $1.00 (minus the exchange fee). If Yes trades at 65 cents, No trades near 35 cents. This ensures the market is internally consistent — one side must win.
15¢
Low probability event
Risk 15¢ to win 85¢
50¢
Coin-flip event
Risk 50¢ to win 50¢
85¢
High probability event
Risk 85¢ to win 15¢
Prices move continuously based on supply and demand. When news breaks that makes an event more likely, traders rush to buy Yes contracts, pushing the price up. When news suggests the event is less likely, Yes prices drop and No prices rise. This real-time price discovery is what makes prediction markets powerful forecasting tools.
Unlike sports betting odds that require conversion between American, decimal, and fractional formats, prediction market pricing is intuitive. The price is the probability. A contract at 30 cents means a 30% chance. No math required.
How to Place Your First Trade
Placing your first prediction market trade is straightforward. Here is the step-by-step process on a CFTC-regulated exchange like Kalshi:
Create an Account
Sign up with your email, verify your identity (required by CFTC regulation), and fund your account via bank transfer, debit card, or wire. Most accounts are verified within minutes.
Browse Available Markets
Explore categories like politics, economics, weather, sports, and culture. Each market lists the question, current Yes/No prices, trading volume, and settlement date.
Choose Your Side
Decide whether you believe the event will happen (buy Yes) or will not happen (buy No). Review the current price, which tells you the implied probability and your potential payout.
Set Your Quantity
Enter how many contracts you want. Each contract pays $1 if correct. Buying 10 Yes contracts at 40 cents costs $4.00 and pays $10.00 if the event occurs.
Submit and Monitor
Confirm your order. Your position appears in your portfolio. You can sell at any time before settlement to lock in profits or cut losses — you are never locked in.
Types of Markets You Can Trade
Prediction markets cover far more ground than traditional sports betting. Here are the main categories available on regulated exchanges:
Politics & Elections
Presidential elections, congressional races, state ballot measures, Supreme Court decisions, and geopolitical events. Political markets are among the highest-volume categories, with contracts on everything from primary outcomes to cabinet appointments.
Economics & Finance
Fed interest rate decisions, inflation data (CPI reports), GDP growth, unemployment figures, and recession indicators. These markets let you trade directly on economic data releases rather than trying to profit indirectly through stocks or bonds.
Sports
Game outcomes, championship winners, award races (MVP, Cy Young), draft picks, and season win totals. Sports markets on prediction exchanges operate differently from traditional sportsbooks — you trade contracts rather than place fixed bets.
Weather & Climate
Hurricane landfalls, temperature records, seasonal rainfall totals, and wildfire activity. Weather contracts are popular with traders who follow meteorological data closely and want to profit from accurate forecasting.
Science & Technology
FDA drug approvals, SpaceX launch dates, AI milestones, and patent rulings. Science and tech contracts attract domain experts who can leverage specialized knowledge into trading profits.
Culture & Entertainment
Award show outcomes (Oscars, Grammys), box office milestones, TV show renewals, and viral social media events. These markets are popular with casual traders who can leverage pop-culture knowledge.
Exchange Model vs. Bookmaker Model
Understanding the difference between a prediction market exchange and a traditional bookmaker is critical. These are fundamentally different business models that affect pricing, fees, and your ability to trade.
Exchange Model (Kalshi)
- ✓ Traders set prices by buying and selling against each other
- ✓ Exchange charges a small fee per trade (typically 1-7 cents)
- ✓ You can exit any position before settlement
- ✓ Prices reflect genuine market consensus
- ✓ No conflict of interest — exchange profits from volume, not your losses
Bookmaker Model (Sportsbooks)
- ✕ The house sets the odds and takes the other side of your bet
- ✕ Built-in margin (vig/juice) of 5-10%+ on each market
- ✕ Limited or no ability to cash out before the event
- ✕ Odds reflect the house's risk management, not pure probability
- ✕ Conflict of interest — house profits when you lose

CFTC Regulation Explained
The Commodity Futures Trading Commission (CFTC) is the federal agency that regulates derivatives markets in the United States, including futures, options, and swaps. In 2020, the CFTC granted Kalshi its Designated Contract Market (DCM) license, establishing event contracts as a regulated financial product.
CFTC regulation means several important protections for traders:
- 1.Segregated funds: Customer deposits are held separately from the exchange's operating funds, protecting your money if the company faces financial difficulty.
- 2.Market surveillance: The CFTC monitors trading activity for manipulation, insider trading, and fraud — the same oversight applied to futures and options markets.
- 3.Transparency requirements: Regulated exchanges must publish trading rules, fee schedules, and settlement procedures. There are no hidden terms.
- 4.Position limits: The CFTC sets maximum position sizes to prevent any single trader from dominating a market and distorting prices.
This federal regulation distinguishes prediction markets from offshore betting platforms and unregulated crypto-based markets. When you trade on a CFTC-regulated exchange, you have the same legal protections as traders on the Chicago Mercantile Exchange or the New York Mercantile Exchange.
