A petition asking TV Globo to fact-check Lula and Flávio Bolsonaro live in its debate passed 400,000 signatures on Tuesday 20 October. Lula’s campaign said the same day that it backs the demand and is negotiating how to make it work, Poder360 reported.
The debate is the last televised face-off before the Brazil election 2026 runoff on Sunday 25 October. Globo’s rules for the debate matter to voters, investors and anyone following the Brazil election odds market.
What the Petition Asks of Globo
The petition, started by a voter named Rafael Brito, asks Globo to run a real-time fact-checking system during the debate. Poder360 identified Change.org as the platform, and Bahia Notícias counted 327,339 signatures on Tuesday afternoon.
By Tuesday evening Poder360 counted more than 418,000. The petition follows the runoff debate on the Band network on Sunday 18 October, which it says was marked by disinformation.
Lula’s Campaign Backs the Demand
Camilo Santana, a senior figure in Lula’s campaign, said fact-checking is essential so Brazilians know the truth about what is said in debates, according to Poder360.
The campaign says it is negotiating a way to make live checking possible. Neither source reports a position from the campaign of Senator Flávio Bolsonaro, the conservative candidate of the Liberal Party (PL).
What Happens at the Globo Debate
Globo will host Lula and Flávio Bolsonaro on Friday 23 October, two days before voters decide. Any on-air corrections would be Globo’s decision.
Polymarket, a prediction market where users bet real money, gave Flávio an 80% chance of winning and Lula 20% on Tuesday night. Those prices are bets, not polls, and they sit beside official polling and results, never in place of them.
What It Means for US Readers
The debate is the last big televised moment before the vote, so how it is run matters to investors tracking Brazilian markets. A claim on trade, taxes or the budget corrected on air could shape views of the candidates before Sunday.
The petition also shows how tightly the campaign has become a fight over information. For readers outside Brazil, the signature count is a measure of public pressure, not of voting intentions.
What Is Not Known
Neither source reports a Globo response, so it is unclear whether the network will add live fact-checking. It is also unknown whether Flávio Bolsonaro’s campaign would accept it.
