As reported by CNBC:
Brazilians will decide in just under three weeks whether to reelect incumbent president Luiz Inácio Lula da Silva or oust him in favor of Flávio Bolsonaro — the son of former president Jair Bolsonaro — as both advanced to a runoff after receiving the most votes in the first-round vote on Sunday.
But the results of the first round are recalibrating how investors are pricing what the final decision will be. Speculators on prediction market platform Kalshi now give Bolsonaro a more than 80% chance of winning the presidency.
Before Sunday's first-round results came in, he had about a 60% chance to win. On Polymarket, Bolsonaro's odds are now 85%, jumping from 63% before the first-round count.
While Bolsonaro was seen as a narrow favorite to win the presidency before Sunday's first round, he was widely expected to trail the incumbent Lula in that initial tally, according to polls before the Sunday vote.[1]
