Polymarket's crypto Up/Down markets are binary contracts on whether bitcoin, ether, solana or XRP finishes a fixed window above where it started. A new market is created for every window — 288 times a day for the 5-minute family — which makes them an unusually dense source of clean, short-horizon prediction-market data.
AymarData records the full order book and every trade for each window with exchange and receive timestamps, and keeps it from 2025-06-01. The 20 families below hold about 161.9M events in total; BTC 15m alone accounts for 24.8M.

FAQ
Common questions
What Polymarket markets does AymarData record?
Crypto Up/Down windows for BTC, ETH, SOL and XRP at 5-minute, 15-minute, hourly, 4-hour and daily lengths, plus the highest-volume event markets. History begins on 2025-06-01.
Why is each Up/Down window a separate market?
Polymarket creates a new market, slug and token pair for every window. Our market ids use the family name (for example btc-updown-15m) and add the window-start Unix time for a specific window.
Can I join Polymarket data with the spot price it settles on?
Yes. All sources share timestamp conventions, so you can join a window's trades with Binance spot or perp ticks for the same coin and measure how far the Up price lags spot.
