Flávio Bolsonaro is not the established frontrunner of the Brazilian right and faces substantial legal and political headwinds, making an 85% market expectation of his victory entirely ungrounded.

Edge: The market massively overvalues Flávio Bolsonaro's chances at 85% Yes, whereas right-wing alternatives (like Tarcísio de Freitas) or an incumbent/left-wing candidate are far more probable winners.

At an implied 85% probability, this market is heavily mispriced due to extreme political volatility, incumbent advantages, and Flávio Bolsonaro not even being the undisputed leader of the Brazilian right. Investors should immediately take the "No" at 15% (yielding a potential ~566% ROI), exploiting the deep $1.9M liquidity to hedge or fade an overextended sentiment trade nearly two years before the election.
