Key takeaway: Prediction markets enable you to trade on outcomes of actual events. You purchase YES or NO shares that are worth $1 upon a correct prediction. Trading here requires less complexity than equities, and you can begin with just $1.
Greetings to the world of prediction markets. Should you have ever remarked "I reckon that will occur" — your mindset already aligns with prediction market participants. The distinction lies in committing genuine capital to your belief and earning returns when your assessment proves accurate. This introductory resource on prediction markets will have you executing trades within five minutes.
How prediction markets work (the 60-second version)
Prediction markets establish tradeable propositions centred on forthcoming occurrences. Consider these illustrations:
- "Will the Fed cut interest rates in June?" — YES shares at $0.65, NO shares at $0.35
- "Will Bitcoin close above $90K on December 31?" — YES shares at $0.55, NO shares at $0.45
- "Will France win the 2026 World Cup?" — YES shares at $0.13, NO shares at $0.87
Every share delivers a payout of $1 when the event materialises, or $0 when it does not. Market pricing embodies collective probability assessment. Should you believe the consensus misjudges the likelihood, you can transact — and profit when events unfold as you anticipated.
Step 1: Choose a platform
Two prominent prediction market venues dominate the landscape:
- Polymarket — leading in transaction volume, operates via cryptocurrency (USDC on Polygon blockchain), available internationally (excluding US)
- Kalshi — authorised by the CFTC, operates in US dollars, restricted to US participants
PolyGram connects you to Polymarket's depth of liquidity whilst offering a streamlined user experience — straightforward email registration, no blockchain wallet required, and optimised for mobile devices. We suggest commencing with this option.
Step 2: Fund your account
PolyGram streamlines the deposit procedure. Funding options include debit card or digital asset transfers. Begin modestly — £7-35 suffices for initial transactions. You retain the flexibility to increase your balance whenever desired.
Step 3: Find a market you understand
Newcomers frequently stumble by participating in markets outside their domain knowledge. Concentrate on subjects you monitor regularly:
- Interested in governance? Explore electoral prediction markets
- Enthusiast of athletics? Participate in competitive event outcomes
- Engaged with digital currencies? Wager on price thresholds
- Tracking technology sector? Forecast announcements and policy shifts
Step 4: Place your first trade
Navigate PolyGram's markets page and identify a proposition where you contest the prevailing valuation. Suppose the consensus reflects 40% likelihood whilst you assess it at 60%, you would acquire YES shares. Your potential gain if correct: $1.00 - $0.40 = $0.60 per share (equating to a 150% gain).
Step 5: Manage your position
Upon acquisition, you face three pathways:
- Hold until resolution: Remain invested until the event concludes. Upon a correct forecast, shares automatically yield $1
- Sell early: Should pricing shift favourably before settlement, you may liquidate your holding for gains without awaiting completion
- Cut your losses: Should circumstances shift your perspective, exiting at a loss proves preferable to maintaining a deteriorating position
Risk management for beginners
- Avoid committing more than 5% of your account balance to any individual proposition
- Prioritise venues with substantial participation (elevated trading volume, minimal bid-ask gaps) — sidestep obscure markets with sparse activity
- Document your outcomes to recognise patterns in your decision-making
- Keep perspective: markets showing 90% certainty still fail roughly once per ten occurrences
