Tracks the leading outcome in a winner-take-all prediction market set with 3 outcomes.

Why this matters:
This 13% probability reflects a low likelihood that Anthropic will release an Opus 6 model before September 1, 2026—roughly two and a half weeks from today. The low pricing reflects the tight timeframe combined with Anthropic's typical development cadence; Opus 5 has been their leading model for over a year, suggesting longer intervals between major releases. The probability would move significantly based on any official Anthropic announcement or credible reporting about an imminent Opus 6 launch. The main catalyst for resolution is whether Anthropic makes a public release or announcement by September 1st. If the date passes without release, markets would likely reprice toward later October or November deadlines, where contract prices currently range from 3% to 12%, suggesting most traders expect a later 2026 launch if one occurs at all.

Key factors:
- Anthropic has not announced or hinted at an Opus 6 release date; lack of pre-announcement communication historically precedes major releases by weeks
- The current timeframe (August 13 to September 1) is only 19 days, which is unusually short for a major model launch cycle in Anthropic's historical pattern
- Contract prices rise substantially for October and November deadlines (10-12%), indicating market consensus expects a later release, not early September
- Kalshi contract volumes are highest for the November and October 16 dates ($1,653 and $973 respectively), suggesting traders view those as more probable outcomes
- No credible news reports or industry indicators as of mid-August 2026 suggest an imminent Opus 6 announcement

## 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.
