Lula’s campaign asked Brazil’s electoral court on October 21 to annul Flávio Bolsonaro’s ticket and bar him from office for eight years, accusing Meta and X of favouritism and alleging abuse of economic power. The filing reached the TSE four days before a runoff that recent polls put within the margin of error. Nobody can say who’s ahead.
The runoff takes place on October 25, three days from now. The TSE will provide the official result.
The Case Before the Court
Filed one day before Thursday’s reporting, the action asks Brazil’s courts to address an issue that reaches beyond one candidate. Lula’s campaign says economic power and favouritism by Meta and X tilted the contest. Those are the campaign’s allegations, and the court hasn’t ruled on them. Still, they point to a live debate: who sets the rules of a modern election when private technology companies control how voters see and share information?
A broader regional report described the moment in similar terms. Countries across Latin America, it said, are contesting who controls the rules: the platform, the regulator, the court or the vote. It described a shared mood of suspicion and distraction, calling this a correction, not a crisis.
What Traders Think, and Why It Isn’t a Poll
As of 11:34 p.m. ET on Wednesday, October 21, Polymarket traders put Flávio Bolsonaro’s chance of winning at 78.5 percent and Lula’s at 21.5 percent. About US$191.2 million had changed hands. The report stressed that these figures represent bets, not polls, and can shift within minutes of a debate or a new survey.
That caveat matters. The gap between a 78.5 percent market price and polls showing no clear leader is wide. Foreigners holding Brazilian assets were advised to expect volatility until the runoff. At the October 21 close, the Ibovespa stood at 206,495, down 0.86%, while USD/BRL was 5.0243, down 0.07%.
Across the Region
Elsewhere, the mood remained unsettled. In Mexico, the peso fell about 1.4% to roughly 18.7 per dollar ahead of Thursday’s mid-month inflation report, while the stock market rose 1.4% to 70,250. The report described uncertainty about direction, not panic.
In Argentina, the Chamber of Deputies voted 162-77 on October 21 to approve harsher penalties for vandalism and attacks on rural property, including sentences of up to eight years. The bill now goes to the Senate. According to the report, the measure aims to protect foreigners with agricultural or land assets and signals a more punitive social climate, as part of a broader shift toward law-and-order politics.
In Colombia, the telecoms regulator CRC warned that after Claro and Azteca integrate, Claro would be the only fibre provider on 778 routes. The regulator wants strict access conditions if it approves the deal. It’s a reminder that public regulators can still set terms for concentrated markets.
In Chile, the IPSA rose 0.54% to 10,986 as the peso weakened to about 980 per dollar. A weaker peso, the report noted, could raise import costs, hitting household budgets first.
Why This Matters:
With a runoff this close and a legal challenge over platform influence pending just days before voters go to the polls, democratic institutions face a test: can they credibly referee contested elections? The TSE’s handling of Lula’s complaint will shape confidence in the result, whichever candidate wins. Allegations about Meta and X also raise a question regulators across the region face: how much power should private platforms hold over political information? The costs of uncertainty don’t fall evenly. Investors can hedge currency swings; households can’t hedge higher import prices caused by a weaker peso. Argentina’s penalty bill and Colombia’s telecom warning show governments choosing between punishment and oversight, between protecting property and protecting competition. Those choices will hit hardest those with the least room to absorb them.
