Crypto price markets are the most volatile category on Polymarket by a significant margin. Unlike sports markets that resolve on a fixed schedule, crypto markets trade around the clock and respond to news events, regulatory announcements, macroeconomic data releases, and sentiment shifts that can arrive at any hour.

What makes crypto markets particularly volatile is the event-driven nature of price moves. A single tweet, an ETF filing, a Fed statement, or a liquidation cascade can move Bitcoin's price 8% in an hour, and the Polymarket binary market will reflect that instantly. The hourly average absolute price change for crypto markets is typically 3-5x higher than for NBA markets.

Lead Changes

Lead Change Distribution

How many times did the market leader flip during the market's lifetime? Zero means one side dominated from open to close. Higher numbers mean contested, back-and-forth outcomes: the kind that create the most trading opportunity.

Probability Ranges

Probability Range by Market

Each bar is one resolved market. The coloured zone spans from the winner's lowest point (left edge) to the loser's peak (white marker) — this is where a reversal was possible. The dim green tail extends from the loser's peak to 100%, where the winner eventually resolved. A wide red zone means the market was nearly overturned.

Reversal Timing

When Did Reversals Happen?

Each dot is a market that had at least one lead change. The x-axis shows when the last reversal happened as a percentage of the market's total lifetime. Points in the shaded red zone (75-100%) reversed in the final quarter, the highest-risk window for certainty sellers.

Trading Angle

Crypto markets offer the richest arbitrage windows of any category, but also the highest mean-reversion risk. Sharp price moves that push a binary market to 80%+ are frequently followed by partial reversion within 24 hours as the underlying price stabilises. Selling the initial spike (taking the underdog position immediately after a large directional move) has historically been positive expected value in BTC and ETH price markets.

Calibration

Calibration Curve

When a Crypto market prices the favourite at 80%, does it actually win 80% of the time? Points below the dashed diagonal mean the market is overconfident. Each coloured line shows calibration at a different stage of the market's lifetime; systematic deviation is where the edge lives.

Upset Probability

Upset Probability Matrix

If the favourite is at X% at this stage of the market, how often does the underdog still win? Red cells are where the market is systematically overconfident. The Late (80%) row is the most actionable: this is where traders decide whether to fade certainty or follow momentum.

Smart Money

Where Smart Money Enters

Every $10,000+ trade on a Crypto market plotted by two dimensions: what probability was the market at when the trade happened (x-axis), and how far through the market's lifetime it was placed (y-axis). Brighter cells mean more large-capital entries at that combination. A cluster at low probability early suggests informed contrarian positioning. A cluster at high probability late suggests momentum-following by large accounts.
