Bookmaker reviews: who checks out, who prices best

Every book Omenizer tracks, scored on what we can verify — who runs it and under what licence (✓ = read on a cited source), how its prices measure against the market, whether a price it posts actually holds, and how its apps rate with users. Ranked by median margin (overround, measured across every market we tracked in the last 7 days — lower means better prices); click any column header to re-sort. Refreshes daily. What the same bet costs at every book →

Prediction markets

Venues where prices are set by traders rather than a bookmaker. The figure below is the typical two-sided spread on their order books — measured the same way, but it is not a bookmaker's margin and is not ranked against one: no operator set these prices, and fees (where they exist) are charged separately.
