Who you're reaching
Prediction Market Tools is edited by Simon Stern. The site is independent of every platform listed here — we accept no payment for tool inclusion or editorial coverage, and corrections are published openly. Every email below comes straight to a real person; we typically reply within two business days. Time-sensitive press requests usually get a same-day response if sent before 5pm Eastern.
If you're reporting an error in a guide or an out-of-date screenshot from a platform, the fastest path is the editorial email below with the page URL and the specific claim. If you built a prediction-market tool and want it listed, the submission form is the right channel — we don't accept inclusion via cold email or DMs.
For interviews, podcast guesting, or speaking requests, use the press address. For dataset or research access (we publish under RSL 1.0 with attribution), the research address.
