What is the Orrery Daily Brief?

A free, one-page morning summary of what changed in prediction markets in the last 24 hours. It covers biggest probability moves, unusual volume, research observations, smart-money flow, events resolving today, and resolution risk. The brief is generated automatically from the live Polymarket public API and is not a trade recommendation.

How is the brief generated?

Each morning, Orrery fetches the top 200 active Polymarket markets by 24h volume, computes deterministic signals over the highest-volume slice, aggregates whale trades >= $5,000 by wallet and market, and ranks events by resolution proximity. Everything is sourced live from Polymarket's public Gamma, CLOB, and Data APIs.

How can an LLM or agent read this brief programmatically?

A machine-readable Markdown variant lives at https://orrery.me/brief/markdown. The same data is also available as structured JSON via the public read-only API at https://orrery.me/api.

Does Orrery recommend trades?

No. Orrery is a public read-only intelligence layer. Signals describe why a price moved, not whether to trade. Orrery does not provide investment, legal, or tax advice.
