AI insight

This is a quantitative read derived from live Polymarket data only — no AI or news research was performed. Connect Ollama for local open-model analysis, or a hosted AI key for web-grounded research. Structurally: liquidity is thin, so the printed probability can move sharply on small orders, and the 0.2-point 24h move suggests no major new information in the last day.
