Up prices are Polymarket US’s best bid and offer for the Up side, in cents; Kalshi’s column is its own YES mid for the window that closes at the same minute, shown only when its target equals Polymarket US’s price to beat. A price more than 60 seconds old is hidden. Not every market we cover is listed on Polymarket US.
18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See https://polymarketexchange.com/files/legal/Polymarket%20US%20Rulebook%20(2026.09.30).pdf for more information.

The 5-minute windows
Polymarket US also runs a 5-minute version of every coin’s window. Kalshi lists no 5-minute crypto market, so those rows have no Kalshi column. A 5-minute window’s book can take a minute or two after the open to post its best bid and offer; until it does, the board shows the market’s own quote, and a quote more than 60 seconds old reads “no current price.”
How they settle, in each market’s own words
This market will settle to Up if the Bitcoin price at 12:00PM ET on Oct 25, 2026 is greater than or equal to the price at 11:45AM ET on Oct 25, 2026. Otherwise, this market will settle to Down. Outcome sourced from CF Benchmarks' Bitcoin Real-Time Index (BRTI), available at https://www.cfbenchmarks.com/data/indices/BRTI. The price at the beginning and at the end of the time range is determined the same way: in the last minute before each of those two times, 60 BRTI prices are collected. The official value for that time is the simple average of these prices, rounded to the nearest 2 decimal places. Please note that this market is about the price according to CF Benchmarks' BRTI, not according to other sources or spot markets.
