Description

This market will resolve to "Up" if the close price is greater than or equal to the open price for the BTC/USDT 1 hour candle that begins on the time and date specified in the title. Otherwise, this market will resolve to "Down". The resolution source for this market is information from Binance, specifically the BTC/USDT pair (https://www.binance.com/en/trade/BTC_USDT). The close « C » and open « O » displayed at the top of the graph for the relevant "1H" candle will be used once the data for that candle is finalized. Please note that this market is about the price according to Binance BTC/USDT, not according to other exchanges or trading pairs.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue:

Polymarket and Kalshi use incompatible price sources (Binance BTC/USDT spot candle vs. CF Benchmarks BRTI index) and measurement windows (1-hour candle close vs. 60-second average), creating potential for non-aligned resolutions despite both referencing April 28, 5 PM ET.

Hero Tip:

Treat these as two separate markets tracking related but distinct price signals. Polymarket is a simple binary (up or down); Kalshi is a granular price-band prediction. Cross-platform basis trades are possible if Binance spot and BRTI index diverge. Confirm BRTI index composition and exact UTC/EDT conversion before settlement.

Critical Divergence Points:

  • Polymarket:

    Binary up/down resolution based on Binance BTC/USDT 1-hour candle. Resolves UP if close >= open, DOWN otherwise. Single exchange, single pair, single candle. Quote: 'The close C and open O displayed at the top of the graph for the relevant 1H candle will be used once the data for that candle is finalized.'
  • Kalshi:

    80-way price-band resolution based on CF Benchmarks Bitcoin Real-Time Index (BRTI) 60-second simple average before 5 PM EDT. Resolves YES if BRTI falls within any of 80 discrete $250 bands (67750-67999.99 through 87249.99+). Quote: 'If the simple average of the sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) before 5 PM EDT is between [range]...then the market resolves to Yes.'
