Supreme Federal Court Justice Flavio Dino ordered federal police on October 27 to investigate possible illegal foreign financing of defeated candidate Flavio Bolsonaro's presidential campaign, including contacts involving the US Rockbridge Network co-founded by JD Vance.


Brazilian Supreme Federal Court Justice Flavio Dino ordered federal police on October 27 to open an inquiry into possible illegal foreign financing of defeated presidential candidate Flavio Bolsonaro's campaign, including by a group linked to US Vice President JD Vance. The order, in case ADPF 1178, directs investigators to examine whether foreign resources, services or other benefits reached political campaigns and whether intermediaries were used to conceal them.

Police were told to probe contacts involving the Rockbridge Network, a US-based group co-founded by Vance, and Brazilian businessmen Tallis Gomes and Pedro Sang, to determine whether any resources, services or other economically valuable benefits were connected to the campaign. The inquiry also covers election advertising linked to Polymarket, a US-based predictions site whose services are prohibited in Brazil, and Meta Platforms, including whether internet companies engaged in deliberate algorithmic manipulation or created intentional disparities helping or hurting candidates.

Investigators must also examine whether any prospective campaign financing was connected to foreign economic interests in Brazil's rare earths and other critical minerals, which are state property whose exploitation depends on authorisation in the national interest. The inquiry runs under Supreme Federal Court supervision because, Dino wrote, members of Congress may be involved. It follows Bolsonaro's defeat by President Luiz Inacio Lula da Silva in the October 25 runoff, and Bolsonaro's departure for the United States on the day of the order after missing a deadline to hand his passports to federal police in a separate money-laundering inquiry.

The order itself is the established fact, reported from the court filing by Bloomberg and corroborated by two further accounts; what it does not establish is wrongdoing. Dino stressed that the order does not assert that illegal foreign financing occurred, only that allegations levelled during the race warrant investigation. The denials are on the record and preserved here: Rockbridge has said Brazilians made false statements about their relationship with it and produced documents in its name without its knowledge or consent, and that its Brazilian company never operated; Bolsonaro's office has said the campaign received no foreign money or structure; Meta has denied favouring a specific candidate; and Vance's office did not immediately respond to a request for comment.

Brazilian law prohibits candidates and parties from receiving money or other economic assistance from foreign entities or governments, and Dino's order treats that ban as covering any economically measurable advantage even where no money changes hands, with the source of the resources deciding whether a donation is foreign whatever the nationality of the person handing it over. The allegations against Rockbridge and the two businessmen were raised by former presidential candidate Renan Santos, who did not reach the runoff.

No public federal police findings had been reported when the order was covered, and the next step is the investigation itself: identifying who paid foreign-based social media accounts that posted election content derived from Polymarket predictions, tracing the source of the funds, and determining whether people or organisations in Brazil knowingly participated.
