Pinnacle
In short: A Curaçao-licensed offshore sportsbook widely regarded as the sharpest in the world. Pinnacle accepts unlimited stakes from professional bettors, posts lines with industry-low vig of 2–3%, and uses its order flow to set the closing line that other sportsbooks copy.
Also known as: Pinny, Pinnacle Sports
Pinnacle’s lines are treated as the reference benchmark across the serious betting industry. Because the book welcomes sharp action rather than limiting it, its closing line is generally considered the closest thing to a fair price the market produces — which is why CLV is most commonly measured against Pinnacle. Pinnacle does not accept US customers, but its number still matters as a price reference: other sharp books and exchanges tend to converge on Pinnacle as the event approaches.
