Prediction markets allow traders to buy contracts linked to future events, including elections, interest rates, sporting competitions and cryptocurrency prices. Growing participation has attracted crypto exchanges seeking additional revenue opportunities as digital asset trading becomes increasingly competitive.
Most contracts offer two outcomes: Yes or No. A Yes contract priced at USD 0.65 suggests traders collectively assign a roughly 65% probability to an event, although that estimate may be wrong.
If the event occurs, a winning contract typically pays USD 1. Someone buying at USD 0.65 earns USD 0.35 before fees; if the prediction fails, the buyer loses USD 0.65.
Prices respond to new information and shifting demand. Contract wording matters since designated resolution sources determine whether a payout is due.
According to CoinGecko's first-quarter 2026 industry report, prediction-market notional trading volume reached USD 75.1 billion between January and March, up 72.4% from USD 43.6 billion in the preceding quarter.
Kalshi accounted for 40.8% of quarterly volume, while Polymarket represented 38.2%, indicating that two platforms handled nearly four-fifths of reported activity.
Separately, DefiLlama reported monthly volume of USD 19.06 billion in July 2026, compared with USD 955 million in July 2025. That represents an increase of approximately 1,896%.
However, notional trading volume measures transactions rather than unique deposits. Frequent buying and selling can increase reported turnover without a corresponding rise in capital committed.
Crypto exchanges can use prediction markets to attract existing customers, diversify fees and offer exposure to events beyond cryptocurrency prices.
According to The Block, Crypto.com and Gemini were among companies developing event-contract products as the sector expanded. Galaxy Research also examined Hyperliquid's HIP-4 initiative, which introduced outcome-based markets in 2026.
Blockchain infrastructure can facilitate stablecoin payments and automated settlement, although blockchain-based contracts still depend on reliable information about real-world outcomes.
In the United States, disputes persist over whether certain sports-related contracts fall under federal derivatives oversight or state gambling laws. Rules can affect which products platforms may offer and where customers can trade.
Participants face potential total losses, thin liquidity, wide bid-ask spreads and disputed outcomes. Market-implied probabilities may also reflect speculation or manipulation rather than accurate forecasts, especially during periods of volatility.
Why this MattersPrediction markets turn expectations about future events into tradable prices, offering information signals and new business opportunities for crypto platforms. However, expanding participation also raises questions about regulation, market integrity, settlement reliability and investor protection across jurisdictions.
Prediction markets are becoming a significant product category across crypto and traditional finance. Investors should examine contract terms, resolution criteria, fees and legal availability before trading. Rapid growth alone does not establish that event prices accurately predict future outcomes.
