Senator Flávio Bolsonaro, son of former President Jair Bolsonaro, is set to face incumbent Luiz Inácio Lula da Silva in a run-off election for Brazil's presidency on October 25, having secured 47% of the vote in the first round against Lula's 45% [4][9][11]. This election outcome could significantly reorient Brazil's international relations, particularly concerning its alignment with the United States and its approach to economic partnerships with countries like China [8][9][10].

For readers, the outcome of this election matters because it will determine Brazil's foreign policy direction, impacting trade relations, regional security initiatives, and its stance on global geopolitical issues, including its relationship with the U.S. and China [7][8][9].

## What the records show

Senator Flávio Bolsonaro received 47.03% of the valid votes in the first round of Brazil's presidential election on October 4, ahead of President Luiz Inácio Lula da Silva, who secured 45.16% [11][12]. The runoff election is scheduled for October 25 [1]. Bolsonaro's campaign platform prioritizes closer relations with the United States, Israel, and Argentina [7][9]. He has proposed that Brazil join the U.S.-led "Shield of the Americas," a regional security initiative aimed at coordinating efforts against transnational criminal organizations [2][4]. Bolsonaro has also stated his intent to transfer Brazil's embassy in Israel from Tel Aviv to Jerusalem [3]. A group of Brazilian bishops released a letter on October 22, urging Catholics not to vote for Flávio Bolsonaro, stating that his candidacy "directly threatens several major tenets of the Church's social doctrine, the existence of democracy, national sovereignty, and the pursuit of the common good" [1].

## Timeline

On May 26, 2026, Flávio Bolsonaro met with then-President Donald Trump at the White House [10][14]. Days later, on May 29, Bolsonaro stated he discussed Brazil's potential entry into the "Shield of the Americas," a U.S.-led security initiative established by the Trump administration on March 7, 2026 [2]. On June 2, 2026, Trump publicly praised Flávio Bolsonaro following their White House meeting [16]. The following day, on June 3, Bolsonaro stated he asked President Trump not to impose tariffs on Brazilian companies [13]. In July 2025, the Trump administration had imposed steep trade tariffs on Brazilian exports [1][10]. The first round of Brazil's presidential election occurred on October 4, 2026 [11]. On October 22, 2026, a group of Brazilian bishops released a letter urging Catholics not to vote for Flávio Bolsonaro in the upcoming runoff [1]. The second round of the presidential election is scheduled for October 25, 2026 [1][11].

## What changed and for whom

The current election marks a significant moment following the conviction of Jair Bolsonaro, Flávio Bolsonaro's father, who is serving a 27-year term under humanitarian house arrest for conspiring to overturn the 2022 election results [7][12]. Flávio Bolsonaro's campaign strategy explicitly seeks closer alignment with Washington, particularly on trade and security, which contrasts with incumbent President Lula's approach of diversified partnerships and multilateral diplomacy [8]. This shift could lead Brazil away from Lula's "active non-alignment" course towards a more pro-U.S. foreign policy, potentially impacting its relationships with Europe and the Global South [7][10]. The renewed influence of Donald Trump, who has explicitly backed Flávio Bolsonaro, also signals a potential reorientation of U.S.-Brazil relations [1][10].

## What the subject has said publicly

Flávio Bolsonaro has been vocal about his intentions for Brazil's foreign policy. He stated that he asked President Donald Trump not to impose tariffs on Brazilian companies [13][16]. During a March Conservative Political Action Conference in Dallas, Texas, he called on Washington to monitor Brazil's elections, compared his father to Trump, and described Lula as "anti-American" [1]. Bolsonaro further indicated that under his leadership, Brazil would be a strategic U.S. partner in supplying critical minerals and rare earths [1]. He confirmed discussing Brazil's potential entry into the "Shield of the Americas" [2] and pledged a free trade deal with the United States [4]. He has also stated his preference for bilateral relationships, specifically with the U.S., Argentina, and Israel [9], and mentioned he would reassess Brazil's membership in BRICS if elected [7][9]. Bolsonaro supports Trump's decision to designate Brazil's largest criminal organizations as terrorist groups [10].

## What we could not confirm

PrimaryBrief could not confirm the specific details of the free trade deal Flávio Bolsonaro promised with the United States [4]. The precise impact on relations with Arab countries from his stated intent to move Brazil's embassy to Jerusalem could also not be confirmed [3]. We also could not confirm the exact nature of the lobbying efforts by Eduardo Bolsonaro and his allies regarding the application of the Magnitsky Act against Supreme Court justices [1]. Finally, it remains unconfirmed whether Flávio Bolsonaro's stated "economically pragmatic" relationship with China would lead to concrete policies that conflict with his strongly pro-U.S. platform [4][9].
