The Kalshi Bitcoin 15-minute window (KXBTC15M) trading right now: its official strike once Kalshi posts it, the time left, what it costs to buy Up or Down at this moment, and a Coinbase spot price for reference. It resolves Up if the 60-second CF Benchmarks BRTI average at the close is at least the strike. This page shows the market only. It does not show our model's read or any signal.

Data comes from Kalshi's public market API through our server, cached for about five seconds, so it can trail Kalshi's own screen by a few seconds. An ask is the cheapest price someone is offering right now; it can move before you trade. Fees are extra: work them out with the fee and breakeven calculator.
The strike is the simple average of CF Benchmarks' BRTI over the 60 seconds before the window opens. Kalshi shows "TBD" until it publishes that number shortly after the open; this page does the same rather than guess with a spot price.
On the simple average of the 60 BRTI prints in the final minute. If that average is at least the strike, Yes (Up) wins, so an exact tie goes to Up. In 24,941 windows we checked there were 0 exact ties.
No. It is a Coinbase spot price shown for reference. Kalshi settles on a 60-second CF Benchmarks BRTI average. A spot read at the close disagreed with Kalshi's official result on 4.40% of 18,001 windows in our data, mostly close calls.
A new window opens every 15 minutes, on the quarter hour, around the clock, except during Kalshi's Thursday maintenance from 3 to 5 AM ET.
No. It shows public market data only: the strike, the time left, the asks and a spot reference. Our model's read is part of the paid Telegram feed, and that feed's record is published in full, losses included.
Our server reads Kalshi's public API at most once every five seconds and the page refreshes on the same rhythm, so figures can trail Kalshi's own screen by a few seconds. If Kalshi does not answer, the page says so and shows how old the last figures are.
This page shows the market. The paid feed adds our model's read.
Our BTC 15-minute feed sends, on most windows, our model's read beside the live Kalshi price about two minutes before the close, to Telegram, around the clock, and grades every call in public. It is sold as coverage and speed. It is not a price advantage: from March 24 to October 4, 2026 the feed won 91.21% of 11,537 graded signals at a 91.74¢ average entry, 0.53 points below breakeven before fees.
Free to read, free to check, and the paid feed is optional.
Every signal in our BTC 15-minute feed goes into a public results log and a downloadable CSV, graded against Kalshi's official result, losses included, with nothing pulled.

These are 15-minute binary prediction-market contracts. Any single window can lose 100% of your stake. They settle on a 60-second index average, not on the exchange chart you may be watching. At high prices a loss costs many times what a win pays, and Kalshi's fee raises the win rate you need above the price. Nothing on this page is financial, investment, or betting advice.
Past performance does not guarantee future results. Trade only with money you can afford to lose. Must be 18+ or of legal age where you live. If gambling is a problem for you, call 1-800-GAMBLER.
