Across the venues we track, the market sets a consensus fair price for each question. When one venue offers a better number than that consensus, taking that single leg is +EV— you’re betting it converges. This isn’t a riskless arb (that’s /arbs, and those are rare) — it’s the directional edge that shows up every day. Ranked by net return on the leg, after fees.

Fair value = midpoint of the venues’ mid-prices (a no-vig consensus across what we see). Net edge charges one leg of friction (1¢ fees + slippage) and is shown as return on the price you pay. The ≈%/yr figure annualizes that net edge by how soon the question resolves (simple, floored at 1 day) — a fast resolver is worth more per year than the same edge locked up for months. Liquid books only. An edge is directional, not riskless — it can move against you before it converges. Model your own fees on the calculator; confirm the live book on each venue before trading.
