Why this matters:
This probability indicates a 57% chance that Anthropic will have the best coding model among AI companies by December 31, 2026. The assessment reflects Anthropic's current standing in code generation capabilities, though the AI coding landscape remains highly competitive. Major factors influencing this estimate include the rate at which competitors like DeepSeek, Baidu, or Alibaba release improved models, as well as how benchmark performance is measured and which tasks define "best." The outcome will become clearer as major AI companies release updated models throughout 2026, with significant announcements likely occurring at conferences, through research papers, or via public model releases. The relatively modest probability suggests meaningful uncertainty despite Anthropic's present position, reflecting the fast-moving nature of AI development and the difficulty in predicting which company will maintain technical leadership in a specific capability by year-end.

Key factors:
- Benchmark performance on coding-specific evaluations (HumanEval, MBPP, LeetCode-style tasks) released by independent researchers or companies through December 2026
- Frequency and quality of model releases from competing Chinese and international AI companies, including DeepSeek, Baidu, Alibaba, and others
- Definition of 'best' coding model—whether measured by speed, accuracy, reasoning ability, or performance on specialized programming tasks
- Adoption metrics and feedback from developers using each company's coding tools in production environments
- Research publications and technical benchmarks released at major AI conferences (NeurIPS, ICML, ICLR) in late 2026

Contracts:
- Which AI company will have the best coding model on Dec 31, 2026?: Anthropic — 66¢ Kalshi $256 (weight 100%)

## 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.
