◆

LOCK means Up and Down can both be bought for less than $1.00 after Polymarket's taker fee. One side always pays $1, so that margin is locked whatever the price does, as long as both legs fill at the shown asks. BUY and SELL come from the model and are estimates, not guarantees.

Exchange feeds

Each composite is the mean of live exchange prices after dropping any feed more than 0.5% from the median. Hourly and daily markets settle on Binance, so they use the Binance price while it is live.

How the calls work

What decides each market, what we tested, and what we're still measuring.

Settlement · 5M and 15M60-second averages

The price to beat is the average Chainlink price over the 60 seconds before the window opens. The final price is the same average over the last 60 seconds. In the final minute, part of the result is already counted, which is what Near-certain calls use.

Settlement · 1H and 1DBinance candles

Hourly markets compare Binance's hourly open and close. Daily markets use the close of Binance's 12:00 PM ET one-minute candle. The site reads these numbers directly from Binance.

Backtest · 1,148 BTC windowsThe market is hard to beat

Over 72 hours of 5- and 15-minute windows, a plain volatility model did not beat Polymarket's own prices after fees. So we don't sell model leans as an edge. Locks and Near-certain calls are graded live on the scorecard below.

Price-to-beat accuracy · liveChecking…

Each 5- and 15-minute price to beat we compute is compared with Polymarket's official number once it's published, usually 10 to 20 minutes after the window closes.
