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

Why this matters:
This 15% probability reflects market expectations that Anthropic will release Claude 5 (referred to as "Mythos" in the contracts) before December 1, 2026—roughly four months from now. The low probability suggests traders view this timeline as unlikely, given typical AI development cycles and the fact that Claude 4 was released in 2024. The probability would rise if Anthropic announced a specific launch date, showed public demos, or released developer previews. Conversely, it could fall further if the company signals extended timelines or focuses resources on other products. The main uncertainty driver is Anthropic's actual development progress and release strategy, which remains largely opaque to outside observers. Resolution will occur definitively on December 1, 2026, when either the product has launched or the deadline passes.

Key factors:
- Anthropic has not announced a Claude 5 release date or public timeline as of August 2026
- The November 1 contract trades at only 8¢, indicating skepticism about a release within 68 days
- Historical AI model release cycles from major labs typically span 12-24 months between major versions
- Any official company announcement regarding Claude 5 status would directly move market expectations
- The December 1 deadline is less than four months away, creating time pressure that constrains market probability upward

Contracts:
- Will Anthropic release Mythos before Jan 1, 2027?: Before Jan 1, 2027 — 15¢ Kalshi $1K (weight 89%)
- Will Anthropic release Mythos before Dec 1, 2026?: Before Dec 1, 2026 — 14¢ Kalshi $82 (weight 6%)
- Will Anthropic release Mythos before Nov 1, 2026?: Before Nov 1, 2026 — 8¢ Kalshi $57 (weight 4%)

## 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.
