Analysis

This market estimates a 27% chance the Nasdaq 100 index will fall below $21,000 by December 31, 2026. The probability reflects current market positioning and recent volatility, with the index trading significantly above this threshold as of May 2026. The main drivers of this prediction are macroeconomic conditions—particularly Federal Reserve policy, inflation data, and corporate earnings growth—which determine whether large-cap tech and growth stocks maintain their valuations or face a substantial correction. The most significant catalyst will be the quarterly earnings reports throughout 2026 and any major shifts in interest rate expectations, which directly influence discount rates for high-growth companies that dominate the Nasdaq 100. Economic data releases, especially employment reports and inflation indicators, will provide critical signals about recession risk and monetary policy direction. Resolution depends entirely on where the index closes on December 31, 2026.

  • Federal Reserve interest rate policy and forward guidance; markets price in expectations of rate cuts or hikes that materially affect equity valuations
  • Aggregate earnings growth for Nasdaq 100 components; earnings revisions upward or downward substantially move index valuations
  • Recession probability; historical data shows the Nasdaq 100 typically declines 20-40% during U.S. recessions
  • Geopolitical or systemic financial events between now and year-end that could trigger broad risk-off sentiment
  • Valuations relative to historical averages; current price-to-earnings ratios relative to long-term trends influence downside risk assessment

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
