What is an opinion market?
Prediction markets only work on questions with a factual answer: will the Fed cut rates, will they win the final. But the best arguments have no scoreboard: who is the real GOAT, is that blockbuster a flop, will anyone remember this week's main character next month. 5050 makes those tradeable too, and as far as we can tell we are the only ones running them. The crowd's money sets the favourite; a provably-fair draw, weighted by how the money fell, picks the winning side; and the fewer people on the winning side, the bigger each payout. Agree with the crowd and win small. Back the brave contrarian take and win big.
