Common Knowledge

Every major change begins as a contested claim.

From "Tobacco causes cancer" to "Pocket-sized computers will go mainstream," evidence often arrives long before society can prepare or act. Some ignorance is unavoidable. But delay is costly, and the costs compound.

Common Knowledge measures how much the world is coordinating around a claim, creating a new kind of market that lets us trade, hedge, and produce knowledge about uncertainty that was previously unpriceable.
