Tracks the leading outcome in a winner-take-all prediction market set with 4 outcomes.

Why this matters:
The market assigns a 95% probability that Apple will release the iPhone 18 Pro before June 1, 2027, reflecting high confidence in a near-term announcement. Apple's historical release cadence follows a consistent September launch window, which explains why the October 2026 contract trades at 89%—slightly before the typical announcement date—while later deadlines command higher probabilities. The main drivers are Apple's product development timeline and the company's established fall event schedule. The single biggest catalyst is Apple's expected September 2026 keynote event, where the company typically unveils new iPhone models. If Apple deviates from this pattern or announces a delay, market probabilities would adjust downward significantly. Conversely, early leaks or official confirmation of a September launch would tighten prices toward the October contract.

Key factors:
- Apple's historical pattern of announcing new iPhone models in September suggests an October 2026 release is likely within the typical launch window
- The gap between the October 2026 contract (89¢) and June 2027 contract (95¢) reflects ~6% additional probability for delays, supply chain issues, or production complications
- Zero trading volume across all four Kalshi contracts in the past 24 hours indicates limited market depth and potential illiquidity
- The iPhone 18 Pro naming and numbering convention assumes Apple continues current nomenclature rather than adopting alternative branding strategies
- Official announcements, regulatory filings, or supply chain disruptions by late August 2026 would provide concrete signals about the September release timeline

## 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.
