How to make money in crypto prediction markets?

Delayed arbitrage is currently one of the most efficient structured strategies. Its core logic is: the spot prices on centralized exchanges are updated in real-time via WebSocket, while the probability data in prediction markets is transmitted through oracles, with a delay of several seconds.

Using 15-minute BTC, ETH, SOL “Up/Down” contracts on Polymarket as the battleground. Traders monitor real-time on-chain prices; when BTC rapidly surges on Binance, but the “Up” contract probability on Polymarket remains between 50% and 55%, a significant pricing discrepancy forms.

Key operation points:

• Choose 15-minute short-term contracts with high liquidity and frequent information updates;
• Set the expected value (EV) threshold at least between 3% and 5% to avoid frequent invalid trades;
• Use low-latency VPS, as WebSocket architecture is a technical barrier;
• Take profits early (e.g., within the 0.80 to 0.95 range), and do not hold positions until settlement.

It should be noted that as more quantitative teams enter, the window for this arbitrage is narrowing.

News Event Arbitrage: Front-Running Information Dissemination Paths

The crypto market is highly sensitive to news. Prediction markets rely on oracles like Chainlink to fetch external data, and there is an inherent delay from news event occurrence to probability adjustment.

For example, data from April 2026: the total locked value (TVL) in prediction markets rose from $199 million in October 2025 to $511 million, with open contracts surpassing $1 billion. Geopolitical and macro events drove the main trading volume.

Key operation points:

• Monitor mainstream media and official announcements to pre-judge event trajectories;
• Look for mismatch opportunities in niche markets with low heat but high value;
• Platforms support multi-event combinations for hedging, reducing single-point risk.

Decentralized Betting: Copying “Smart Money” Strategies

Polymarket’s trading volume is highly concentrated, with about 2% of users contributing 90% of the trading volume. By tracking the public trading records of on-chain “whale” addresses, ordinary users can observe the opening positions of top traders and follow them in small proportions.

Key operation points:

• Use on-chain data tools like Dune Analytics to filter addresses with longer holding periods;
• Follow in small batches to avoid slippage caused by synchronized entry and exit with whales;
• Cross-verify signals from multiple large addresses to exclude single misjudgments.

Liquidity Provision and Incentive Betting

Some decentralized prediction platforms distribute tokens as incentives to liquidity providers and market makers. For example, Augur allows users to stake REP to participate in market settlement and earn a share of fees. As of mid-April, Augur’s price was about $0.84; Gnosis was around $120.

Key operation points:

• Calculate whether annualized returns outperform the token’s own price volatility;
• Choose established platforms with security audits and stable operations;
• Be mentally prepared for long-term holding, as token incentives often require lock-up periods.

Summary

Crypto prediction markets are in a period of rapid growth. In March 2026, the number of prediction market trades exceeded 192 million, setting a new record. Kalshi and Polymarket announced simultaneous entry into perpetual contracts, deeply integrating prediction markets with derivatives.

The four main strategies each have their suitable scenarios: delayed arbitrage suits tech-savvy high-frequency traders; news arbitrage tests information acquisition speed; decentralized copy-trading is suitable for conservative participants; liquidity provision is ideal for long-term holders.

Gate has now integrated Polymarket access, supporting both prediction and trading modes. Users can directly participate with USDT via account systems, and also use Web3 wallets on Polygon to participate with USDC. Whatever strategy you choose, starting from Gate allows quick entry into the new track of crypto prediction markets.
