Prediction market vs. futures contract
Published 2026-09-06Reading time: 7 minCategory: Comparative guide
TL;DR
A prediction market is a binary or scalar contract on a discrete event, cash-settled at resolution to $1 for winners and $0 for losers. A futures contract is a scalar contract on a continuous underlying asset, cash- or delivery-settled at expiry to the difference between contract and market price. Both are derivatives regulated under similar frameworks; each covers a different class of risk.
Structural distinction
| Feature | Prediction market | Futures contract |
|---|
| Underlying | Discrete event outcome (Yes/No or bounded numeric) | Continuous asset price (commodity, currency, index, rate) |
| Payoff | $1 if event occurs, $0 otherwise (or scalar in a bounded range) | Difference between contract price and asset price at expiry |
| Settlement | Cash only, at resolution | Cash or physical delivery, at expiry |
| Margin | Full cost of position paid upfront | Initial + variation margin, daily marking to market |
| Position size | Number of contracts × price (0–1) | Number of contracts × contract size (e.g., 5,000 barrels of oil) |
| Trading venue | Prediction market platform (Kalshi, Polymarket, PredictAsiaX) | Futures exchange (CME, ICE, HKEX, SGX) |
| Regulator (US) | CFTC (event contracts on DCMs) | CFTC |
What each covers well
Prediction markets excel at discrete event risk
- Elections. Will Party X win Y country's presidential election in 2026?
- Regulatory decisions. Will the SEC approve a spot Ethereum ETF by Q4 2026?
- Corporate outcomes. Will Company Z report Q3 revenue above consensus?
- Cultural events. Will artist X win Grammy Album of the Year?
- Weather thresholds. Will Tokyo record 40°C+ before September 1?
- Sports outcomes. Will Team X win the 2026 World Cup?
These are events without a continuous price series — a futures contract cannot cleanly cover them.
Futures excel at continuous price exposure
- Commodity hedging. Airlines hedge jet fuel via WTI futures.
- Currency hedging. Exporters hedge FX exposure via currency futures.
- Interest rate hedging. Financial institutions hedge duration via Fed Funds and SOFR futures.
- Index exposure. Portfolio managers gain or shed equity exposure via S&P 500 or Nikkei 225 futures.
- Volatility trading. Traders take positions on future implied volatility via VIX futures.
These require continuous underlying prices — a prediction market's binary structure is a poor fit.
Fee comparison for a $1,000 notional trade
| Venue | Fee structure | Fee on $1,000 notional |
|---|
| Kalshi (event contract) | ~2% of profit | $5–20 (profit-dependent) |
| Polymarket (decentralized event contract) | ~2% at settlement | $5–20 (profit-dependent) |
| PredictAsiaX (Asia prediction market) | 50 bps (0.5%) total taker fee, 5-actor split | $5 (flat, notional-based) |
| CME (S&P 500 futures) | ~$1.50/contract + broker commission | ~$3–8 (fixed regardless of P&L) |
| Interactive Brokers (index futures) | Broker commission $0.85/contract + exchange | ~$3–5 |
Legal treatment in the United States
Event contracts on CFTC-registered Designated Contract Markets are legally a class of futures. Kalshi, Polymarket (in its CFTC-registered subsidiary), and others operate under this framework. The CFTC applies the same derivatives rules to event contracts as to traditional commodity or financial futures — position limits, reporting requirements, anti-manipulation rules. The main legal distinction in practice is category-based: certain categories of event (elections, terror events) are subject to additional restrictions.
Arbitrage between the two
When a prediction market and a futures market reference the same or an easily convertible outcome, prices should converge. Common arbitrage examples:
- Fed rate decision: Prediction market on Fed hikes 25bp at next FOMC vs. Fed Funds futures implied probability. Prediction market prices should converge toward futures-implied by the meeting date.
- Bitcoin price threshold: Prediction market on BTC above $100K at end of Q2 vs. BTC futures with matching expiry. Skew is arbitragable.
- Election-linked equities: Prediction market on election outcome vs. equity futures on stocks known to move with election outcome (e.g., cannabis stocks pre-2024 election).
Prediction markets and futures markets are complementary, not competitive. Sophisticated traders use both.
Frequently asked questions
What is the difference between a prediction market and a futures contract?
A prediction market is a binary or scalar contract on a specific event outcome (Yes/No, or a bounded numeric range) that pays a fixed amount at resolution. A futures contract is a scalar contract obligating delivery of an underlying asset at a future date for a specified price. Prediction markets pay $1 per winning share if the event occurs; futures pay the difference between contract price and asset price at expiry.
Are prediction markets a type of futures contract?
Legally in the United States, event contracts on CFTC-registered Designated Contract Markets are treated as a class of futures contract. However, structurally they differ: futures typically settle to a continuous price of an underlying asset, while event contracts settle to a discrete outcome (0 or 1 for binaries). Both are derivatives, both are regulated under CFTC in the US, but the settlement mechanics and typical use cases differ.
What can prediction markets cover that futures cannot?
Prediction markets can trade any event with a verifiable outcome — elections, court rulings, cultural events, weather thresholds, macroeconomic release outcomes (whether unemployment beats consensus), corporate outcomes (whether a company hits Q4 guidance). Futures require an underlying asset with a continuous price series, so they cannot trade discrete events without additional structuring.
How do fees differ between prediction markets and futures?
Futures exchanges charge per-contract fees (typically $0.20–$2.00 per contract) plus brokerage commission. Prediction markets typically charge percentage-based fees on trade value or profit (1–4%). For small positions the prediction market fee is often lower; for large positions the futures fee (which does not scale with size) is often lower.
Are prediction markets settled by delivery like some futures?
No. Prediction markets are always cash-settled — winning positions receive their payout in stablecoin or fiat, losing positions receive nothing. Traditional futures may settle by physical delivery (for commodities, currencies) or by cash (for financial futures). Event contracts on Kalshi and CFTC-registered venues are cash-settled.
Which is better for hedging real-world risk?
Depends on the risk. Futures work best for continuous price exposure — hedging fuel costs, currency exposure, interest rate risk. Prediction markets work best for discrete event risk — hedging election outcomes, regulatory decisions, weather thresholds, corporate binary outcomes. For a business, having both tools available is optimal.
Do prediction markets have expiration and margin like futures?
Prediction markets have expiration (the event resolution date) but do not have variation margin the way futures do. On prediction markets you post the full cost of your position upfront; there are no daily margin calls. This makes prediction markets simpler to hold but requires more upfront capital per unit of notional exposure.
Can I arbitrage between prediction markets and futures?
Yes, when both markets reference the same event or an easily convertible one. Common arbitrage: prediction market on 'Fed hikes 25bp at next meeting' vs. Fed Funds futures implied probability. Prediction market prices generally converge toward futures-implied probabilities as event date approaches, but temporary divergences create trading opportunities.
