The giant swing is the moment when real information starts hitting the system and overwhelming the signal of degenerate gambler chuds. But it shows the uselessness of betting markets; by the time they're giving Lula 75% odds, pollsters were publishing 95% certainty projections of the final result.
Brazil elected Lula again tonight. Poll averages appear to have had Lula and Flávio Bolsonaro effectively tied, maybe Bolsonaro up 1 on Lula — so not sure why the markets had this race at 80-20 Bolsonaro. Markets might miss big in the U.S. midterms in 9 days too.
