Kalshi
This market predicts whether the simple average of sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) before 5 PM EDT on September 25, 2026 will be above 65499.99. Currently, the leading outcome – that the price *will* be above this level – has a 99.0% probability on Kalshi. Resolution will be based on the BRTI index as reported by CF Benchmarks. Keep a close watch on Bitcoin’s performance leading up to September 25, 2026, as the market will resolve based on the index value at 5 PM EDT on that date.
All markets resolve based on the simple average of the sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately preceding 5 PM EDT on September 25, 2026. For each market, if this average exceeds the specified threshold (e.g., $65,499.99 for the $65,500 or above market), it resolves to 'Yes'; otherwise, it resolves to 'No.' Price validation uses CF Benchmarks' BRTI as the definitive source, distinct from consumer-facing platforms. The final value is calculated from 60 sequential BRTI price points collected during the last minute before 5 PM EDT, ensuring precision through aggregation. All markets share this unified methodology, differing only in their respective price thresholds.
On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing different Bitcoin price ranges. The prices of these contracts determine the implied probability of each outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate, the prices adjust to reflect the collective wisdom of the crowd. The market depth and trading volume—currently $5,778,378—influence the bid-ask spread, impacting the cost of entering or exiting a position. This dynamic pricing mechanism aims to create a liquid and efficient market for forecasting the future Bitcoin price.
This market resolves around Sep 25, 2026, with the outcome determined by the Bitcoin price at 5:00 PM EDT on September 25, 2026. The price will be verified against credible public reporting of the Bitcoin spot price from a widely recognized exchange. Traders holding contracts corresponding to the correct price range will receive a payout, while those holding contracts on incorrect ranges will not. The resolution process ensures a transparent and objective determination of the market’s outcome based on publicly available data.
Several signals and events could significantly impact this market before its resolution. Major regulatory announcements regarding cryptocurrency, particularly Bitcoin, could cause substantial price swings. Macroeconomic factors like inflation rates, interest rate decisions, and global economic growth also play a role. Technological developments related to the Bitcoin network, such as upgrades or security breaches, could influence trader sentiment. Finally, widespread adoption of Bitcoin by institutions or significant shifts in investor confidence could all move this market considerably between now and Sep 25, 2026.
