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

Why this matters:
Markets are pricing a 71% likelihood that China will develop a functional EUV lithography machine capable of manufacturing semiconductors by January 2030, but only a 16% chance this occurs by end-2026. EUV lithography represents the most advanced semiconductor manufacturing technology; China currently lacks domestic capability and faces U.S. export controls on equipment. The timeline reflects uncertainty about both technical feasibility and geopolitical constraints. Key drivers include China's semiconductor R&D investments, ASML's monopoly on current commercial EUV systems, and whether Beijing can either independently develop the technology or acquire critical components despite restrictions. The gap between the 2027 contract (16¢) and 2030 contract (71¢) suggests markets view near-term breakthroughs as unlikely but believe meaningful progress becomes more probable with a 3-4 year window.

Key factors:
- China's existing EUV prototype status: whether demonstrated machines are truly functional or remain lab-stage development
- U.S. export control effectiveness: degree to which sanctions prevent China from acquiring foreign components, materials, or technical expertise
- Third-country access channels: availability of critical semiconductor manufacturing inputs from Netherlands, Japan, or other non-U.S. suppliers
- International verification of claims: how China would confirm operational capability to external observers given security sensitivity
- ASML's technological lead: whether competitors can feasibly close the gap or if the Dutch monopoly remains insurmountable within the timeframe

## 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.
