Flávio Bolsonaro TV Ad Airs Without Sound on Monday

BRAZIL · POLITICS

Brazil’s conservative presidential frontrunner says his free television slot went out on mute on Monday. The electoral court has not yet said publicly what went wrong.

Flávio Bolsonaro’s free TV campaign ad aired without sound on Monday, 12 October, Folha, Metrópoles and g1 reported. Flávio, an ally of US President Donald Trump, faces President Luiz Inácio Lula da Silva in the runoff on Sunday, 25 October.

The slot went out at about 1 p.m. Brasília time on a national holiday, g1 and Metrópoles reported. Flávio said in a video on social media that he did not believe it was a coincidence.

What Happened on Monday

The program was part of the free electoral airtime that Brazil’s open-air TV stations must carry during the campaign. Monday was the feast day of Our Lady of Aparecida, Brazil’s patron saint, as g1 and Metrópoles noted.

The picture went out but the audio was missing, Metrópoles reported, and g1 also said it aired without audio. Flávio called it “mute” in a video quoted by both Folha and Metrópoles.

Lula’s program, which followed in the same block, played with normal sound, Metrópoles reported. Flávio made the same point in his video, which both Folha and Metrópoles quoted.

What Flávio Said

“My electoral program was broadcast without sound,” Flávio said in the video, as quoted by Folha and Metrópoles. “Lula’s had sound, everything OK, but mine was broadcast without sound,” he added.

The senator asked his followers whether they believed in coincidence and said there was no such thing, according to both outlets. Neither outlet reported any evidence that the failure was deliberate.

His campaign said it was still trying to find out what had happened, according to g1 and Metrópoles. None of the three outlets reported a formal complaint to the electoral court.

Who Sends the Signal

Folha, citing the Superior Electoral Court (TSE), said a broadcasters’ media pool at the court retransmits campaign ads. Metrópoles, citing the electoral rules, said instead that EBC, the federal public broadcaster, distributes the video signal that goes on air.

Both outlets said the origin of the failure was still unknown. Folha said the TSE and the pool had not answered its questions, and Metrópoles said EBC had not commented.

What It Means for You

For US investors, the runoff decides who runs Latin America’s largest economy, with effects on the real and New York-listed Petrobras shares. Disputes over fair access to airtime can feed challenges to the result, which markets and Washington watch closely.

Flávio is the eldest son of former president Jair Bolsonaro, who is serving a coup sentence under house arrest. Lula, of the Workers’ Party (PT), is seeking re-election.

What Prediction Markets Say

On Polymarket’s US$180 million market, Flávio Bolsonaro stood at 87% and Lula at 12.5% (12 October, 3:35 p.m. ET). Kalshi, regulated in the US by the CFTC, showed Flávio at 88% and Lula at 13% (11:07 a.m. ET).

Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.

What Is Not Known

The cause of the failure is not known, and no official explanation had been published by Monday evening. Metrópoles reported that the TSE had opened an inquiry, but no second outlet or court statement confirms it.

It is not clear how many stations carried the silent version, or whether radio slots were affected. Folha and Metrópoles also differ on who distributes the signal, pointing to the TSE pool and to EBC respectively.

What Comes Next

An explanation from the TSE, the pool or EBC should show where the failure began. The campaign could also ask the court to air the program again, but no such request had been reported by Monday evening.
