About
Prediction markets put a price on events. Polymarket's public Gamma API lists events, markets and their current odds with no key and no account, and its docs publish an llms.txt index an agent can read.
What it adds to Moby. A view of what is expected to happen. Odds on an ETF approval, a rate decision or an exchange listing tell your agent how much of a catalyst is already priced in. A token running on a story the market prices at 20% is a different trade from one at 90%.
How to pair it. In a research request, have your agent look up the odds on any event the thesis depends on, then check Moby's smart-money and whale tools. If they disagree, say so.
What it does not do. This listing reads odds only. Betting needs a funded Polymarket account and a signing key; do not give your agent either. Polymarket blocks orders from some countries, and thin markets can be noisy.
