From Prediction to High-Frequency Gaming: Polymarket’s 5-Minute Market Gains Popularity

Polymarket’s newly launched 5-minute market allows users to bet on whether Bitcoin’s final 5-minute K-line will close higher or lower, with market makers receiving liquidity rebates. This ultra-short time window further compresses the trading cycle into seconds and fractions of a second.

According to data provided by Blockworks researcher Kunal Doshi, the product generated approximately $25.2 million in trading volume within 40 hours of launch, with an average of about $50,000 traded per 5-minute window, reaching 10% to 20% of the trading volume of the original 15-minute markets.

Why is launching ultra-short-term contracts on Polymarket considered “a good move”?

Doshi pointed out that many compare the 5-minute contracts to perpetual contracts and other directional products, but the two are not directly comparable:

These ultra-short-term contracts are not used to bet on Bitcoin’s price direction; they are more like rapid capital recycling and arbitrage tools.

He cited data indicating that about 7.1% of addresses bought both Yes and No within a single window. Although this percentage is not high, these addresses contributed 7.5% of total trading volume and 23.4% of trading transactions: “They have 72.3% of trades as order matches, 80% of the time windows are profitable, and the median of Yes and No prices combined is about 0.9823.”

Doshi emphasized that this aligns with typical arbitrage logic: when the sum of Yes and No prices is below 1, simultaneously buying both sides can lock in profit from the spread. This indicates that early systematic arbitrage capital has begun to enter, but large-scale liquidity providers are not yet fully in place.

In other words, Polymarket is increasing market efficiency by compressing the time dimension without changing the product’s core nature, thereby expanding market size. Doshi calls this “a good move.”

Will the 5-Minute Market Become a Natural Arena for AI Agent Trading?

Independent researcher Haotian believes that the launch of such high-frequency 5-minute products is more suitable for bots and automated strategies rather than human traders.

In practical terms, arbitrage programs can monitor order book depth on centralized exchanges, capital flow changes, and oracle price feeds simultaneously. When short-term price imbalances are detected, they can open positions on Polymarket within milliseconds:

In a context where rules are clear, settlement mechanisms are fixed, spreads are calculable, and arbitrage opportunities are evident, prediction markets may become one of the first application scenarios for AI trading.

From User Gaming to Big Players Entering the Market: Structural Changes in Prediction Market Participants

Polymarket’s rapid growth and product innovation demonstrate that prediction markets are evolving from event betting platforms into financial infrastructure with high-frequency trading and hedging features. As minute-level contracts and systematic arbitrage activities increase, the composition of market participants may undergo significant changes.

Looking at traditional market-making giants entering the space, whether retail investors can continue to profit remains another question.
