This event tracks the performance of a major stock market index on a specific date, allowing participants to speculate on whether the index will fall within certain numerical ranges at the close of trading. The outcome depends solely on the index's final value at the specified time, reflecting broader market conditions and investor sentiment.
Each market resolves based on whether the Nasdaq 100 index's closing value on August 21, 2026, at 4pm EDT falls within a specific numerical range. Markets close on August 21, 2026, and expire either when the index data is first released or one week after that date, whichever occurs sooner. All markets adhere to these closing and expiration guidelines, with resolution determined exclusively by the index's end-of-day value on the specified date.
Compared to traditional analyst forecasts, prediction market odds for this market often reflect a more immediate, crowd-sourced view of market expectations. While analysts may incorporate macro models and longer-term outlooks, traders in this market price in real-time reactions to news, earnings, and economic data. That can lead to tighter or wider spreads depending on recent volatility. Still, both sources often converge around major events, with this market sometimes showing sharper moves in the days before Aug 21, 2026.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders set the price through a continuous auction where bids and asks determine the current odds. The top outcome’s implied probability reflects the collective assessment of where the Nasdaq-100 will land at the exact close time. Market depth and recent trades feed into the displayed price, adjusting dynamically to new information. Liquidity, measured by $2,286 in 24-hour volume and $3,442 total volume, can shift pricing volatility. As Aug 21, 2026 nears, expectations around key economic reports or tech earnings may cause rapid re-pricing on Kalshi.
This market resolves around Aug 21, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. At that point, the final Nasdaq-100 closing price will be checked against the defined ranges, and the market will settle accordingly. Traders should watch for any last-minute swings in the index as the deadline approaches, since those can decisively tip the outcome.
Several signals could shift this market before Aug 21, 2026. Major tech earnings reports, especially from Nasdaq-heavy companies, often drive short-term index moves and may alter trader expectations. Macro data like U.S. inflation numbers, Federal Reserve policy updates, or geopolitical developments that impact risk sentiment can also cause rapid re-pricing. Liquidity spikes around high-volume trading periods or news events may amplify price swings. As the expiration approaches, any surprise announcements—from regulatory changes to sector-specific breakthroughs—could further influence the odds on Kalshi.
