Brazilians are voting today in the first round of the presidential election, with polls open from 8:00 to 17:00 BRT and the Superior Electoral Court (TSE) publishing official results from 17:00 BRT. Final polling points to a near-certain second round on October 25: Datafolha’s October 3 survey put incumbent Lula da Silva at 42 percent and Senator Flavio Bolsonaro at 40 percent, while AtlasIntel’s September 23-28 survey showed Lula 45.3 to Bolsonaro 42.2, with the runoff simulated at a dead heat of 47.6 to 47.7. No candidate is expected to clear 50 percent of valid votes. [REPORTED]
The economic stakes are unusually direct. Lula has publicly promised a debt ceiling if reelected — a fiscal anchor the bond market will test immediately. On the external side, the US tariff architecture on Brazil, including a 10 percent baseline, a 50 percent effective rate on many goods, and a 10 percent steel deal, hangs on the winner, and Washington’s posture toward the result itself is a market variable: the Washington Post has reported fears of US interference in the process.

The mechanics are confirmed and operational: roughly 160 million eligible voters, six choices on the electronic ballot, about one million overseas voters with expatriate voting already underway. What remains unknown until this evening is the first-round margin, which will shape the three-week runoff campaign — and with the runoff simulated as a dead heat, the campaign itself becomes the main emerging-market political risk between now and October 25.
