Tracks the leading outcome in a winner-take-all prediction market set with 6 outcomes.

Why this matters:
Markets are pricing a 70% chance that the S&P 500 will close above $8,000 by February 1, 2027, but only a 31% chance it reaches that level within the next two weeks by September 1, 2026. This gap reflects market expectations about the timeline for index growth through the remainder of 2026. The probability is primarily driven by the index's current level relative to the $8,000 threshold and implied expectations for equity performance over the next six months. Near-term economic data, corporate earnings announcements, and Federal Reserve communications will influence whether the index gains the required points in the compressed September timeframe. The most significant immediate catalyst is the early September economic calendar, including employment reports and Fed policy signals, which historically move index levels sharply and would begin resolving the near-term uncertainty.

Key factors:
- Current S&P 500 level is substantially below $8,000, requiring roughly 8-12% gains to clear the threshold depending on the exact entry point
- Kalshi contracts show declining probabilities as target dates move closer (31% by Sep 1 vs 70% by Feb 1), indicating market consensus the move is more likely on longer timescales
- August-September typically includes volatile trading around employment data and Fed communications, both of which directly impact equity valuations
- The 24-hour trading volume on near-term contracts ($0 reported) versus October contracts ($84) suggests limited recent conviction in imminent near-term moves
- Historical S&P 500 volatility and typical quarterly price movement ranges will determine feasibility of an 8-12% move within 2-6 month windows

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.

## SF Signal

- SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
- No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only.
