Key takeaway: Prediction markets enable you to trade on outcomes of real-world events. Purchase YES or NO shares that are worth $1 upon a correct prediction. This approach is less complex than equity trading, and entry requires just $1 or more.
Greetings to the world of prediction markets. Whenever you have remarked "I reckon that will occur" — you are already reasoning as a prediction market participant. The distinction lies in the ability to stake genuine capital on your belief and earn returns when your forecast proves accurate. This introductory guide to prediction markets will have you executing trades within five minutes.
How prediction markets work (the 60-second version)
Prediction markets establish tradeable propositions regarding forthcoming events. For instance:
- "Will the Federal Reserve reduce interest rates in June?" — YES shares priced at $0.65, NO shares priced at $0.35
- "Will Bitcoin reach above $90K by December 31?" — YES shares priced at $0.55, NO shares priced at $0.45
- "Will France become champions of the 2026 World Cup?" — YES shares priced at $0.13, NO shares priced at $0.87
Every share yields $1 upon the occurrence of the event, or $0 if it fails to occur. The prevailing market price embodies the collective probability assessment. Should you believe the market's assessment is inaccurate, you may transact — and should your assessment prove correct, you realise gains.
Step 1: Choose a platform
The most prominent prediction market venues include:
- Polymarket — leading in trading activity, blockchain-based (USDC via Polygon), available internationally (restricted in US)
- Kalshi — authorised by the CFTC, operates in USD, accessible exclusively to US residents
PolyGram grants you entry to Polymarket's trading depth whilst offering a more straightforward platform — login via email, no blockchain wallet required, and optimised for mobile devices. We suggest commencing with this option.
Step 2: Fund your account
Funding your PolyGram account is uncomplicated. You may deposit through debit or credit card as well as cryptocurrency transfers. Begin modestly — £7-35 provides sufficient capital for preliminary transactions. Additional funds can be contributed whenever desired.
Step 3: Find a market you understand
A frequent error amongst newcomers involves participating in markets outside their domain of knowledge. Choose an area of genuine interest:
- Interested in governmental affairs? Participate in electoral markets
- Interested in athletics? Engage with match result predictions
- Interested in digital currencies? Trade on price targets
- Interested in innovation? Forecast announcements and policy changes
Step 4: Place your first trade
Navigate to PolyGram's available markets and locate a proposition where the current valuation diverges from your assessment. Should the market indicate 40% likelihood whilst you estimate 60%, acquire YES shares. Your potential return if accurate: $1.00 - $0.40 = $0.60 per share (representing a 150% gain).
Step 5: Manage your position
Upon acquiring shares, you possess three alternatives:
- Retain until conclusion: Await the event's outcome. Upon correctness, shares automatically settle at $1
- Exit ahead of time: Should the valuation shift favourably before conclusion, liquidate for profit without awaiting the final result
- Minimise damage: If circumstances alter your perspective, liquidate at a loss instead of wagering on recovery
Risk management for beginners
- Refrain from risking beyond 5% of your account balance on any single proposition
- Prioritise well-traded markets (substantial activity, narrow bid-ask gaps) — sidestep obscure propositions with minimal participation
- Document your outcomes to recognise patterns in your decision-making
- Keep in mind: even markets priced at 90% probability fail approximately once every ten instances
