    PM 'Bitcoin reach $100,000 by Dec 31 2026' and Kalshi 'Bitcoin above $100,000 by Jan 1 2027' — identical threshold and window. PM 0.095 vs Kalshi 0.12/0.13 — ~2.5pt gap. Note: resolution sources differ — Polymarket uses Binance BTC/USDT 1-minute candle highs; Kalshi uses the CF BRTI trimmed-mean index. A momentary exchange wick can trigger Polymarket but not Kalshi. [confidence: medium]

    This market will immediately resolve to "Yes" if any Binance 1 minute candle for Bitcoin (BTC/USDT) between November 24, 2025, 14:00 and December 31, 2026, 23:59 in the ET timezone has a final "High" price equal to or greater than the price specified in the title. Otherwise, this market will resolve to "No." The resolution source for this market is Binance, specifically the BTC/USDT "High" prices available at https://www.binance.com/en/trade/BTC_USDT, with the chart settings on "1m" for one-minute candles selected on the top bar. Please note that the outcome of this market depends solely on the price data from the Binance BTC/USDT trading pair. Prices from other exchanges, different trading pairs, or spot markets will not be considered for the resolution of this market.

    If the Bitcoin spot price according to the CF Bitcoin Real-Time Index is above $100000.00 starting 02/17/2026 04:00 PM and before Jan 1, 2027 at 12:00AM ET, then the market resolves to Yes. The market resolves based on the CF Bitcoin Real-Time Index (BRTI) using a trimmed mean calculation. The resolution value is calculated by taking all BRTI values for each minute from market issuance until the specified time on the target date, removing the top 20% and bottom 20% of values, then averaging the remaining 60% of values. If the BRTI crosses the threshold at any point during the measurement period (triggering early expiration), the market immediately resolves. If no data is available at the expiration time, the market resolves to No. The market can resolve early if Bitcoin definitively crosses the threshold before the target date and time.

    This market will resolve to “Yes” if Benjamin Netanyahu ceases to be Prime Minister of Israel for any period of time between market creation and the specified date (ET). Otherwise, this market will resolve to “No”. An announcement of Benjamin Netanyahu's resignation/removal before this market's end date will immediately resolve this market to "Yes", regardless of when the announced resignation/removal goes into effect. The resolution source for this market will be official information from Benjamin Netanyahu and the government of Israel; however, a consensus of credible reporting may also be used.

    Resolution rules
    If Benjamin Netanyahu has either officially announced their intention to leave as Prime Minister of Israel or has actually left Prime Minister of Israel before Jan 1, 2027, then the market resolves to Yes. An "official announcement" means a statement by the person themselves, their authorized representative, or the official body governing the office that the person will be departing from the office. Such announcements must be reported by at least one Source Agency to be considered official. The announcement must not specify they are leaving in more than a year from the statement, in which case the market does not resolve to Yes. "Leaving office" means the person no longer holds the office in any capacity, including but not limited to: resignation (effective), termination, removal, impeachment and removal, recall, or the expiration of their term without renewal. Temporary absences such as medical leave, suspension with possibility of return, or delegation of duties while retaining the office do NOT constitute leaving office. Death does NOT satisfy the Payout Criterion for this Contract. Forced departures (termination, impeachment and removal, etc.) satisfy the Payout Criterion even without a prior announcement.
