Manifold prediction markets as of June 17, 2026, present a mixed view of Anthropic's competitive position. While the probability that the @anthropic-ai/sdk npm package will surpass OpenAI's npm package in weekly downloads stands at 80% (Source 3: https://manifold.markets/DroneServices/will-the-anthropicaisdk-npm-package), other markets indicate persistent gaps. The market 'Battle of the version numbers' shows a 96.66% probability that OpenAI leads (5.2>4.5) through mid-2026 (Source 2: https://manifold.markets/Ernie/battle-of-the-version-numbers-opena). DeepSeek V4 is very unlikely to outperform, with only 1.6% probability (Source 1: https://manifold.markets/lumi/will-deepseek-v4-outperform-openai). Claude Opus is not expected to be considered AGI (2.4% probability) (Source 5: https://manifold.markets/ryanmccomb/will-manifold-consider-the-next-cla). The ARC-AGI-3 score for Claude Fable 5 is low-confidence at 24.52% (Source 4: https://manifold.markets/eapache/what-will-claude-fable-5-score-on-a). These probabilities are speculative but suggest a developing ecosystem win (SDK downloads) alongside model capability perceptions that trail OpenAI. This warrants monitoring for actual adoption metrics and product releases.
