Datafolha's 42-38 poll points Brazil's presidential race to a runoff

Lula's 42% and Bolsonaro's 38% ^[2][3] add up to 80 points of Datafolha's voting intentions ^[10]. That leaves 20 points held by neither man ^[11]. Lula is 8 points short of the 50% that Crypto Briefing gives as the runoff threshold ^[12][4]. On the poll's own base, he would need two of every five of those 20 points to finish the race on Sunday ^[13]. A Lula total above 50% would prove the runoff call wrong, and neither source projects one ^[4][1].

The runoff tests say more. Crypto Briefing reports the two nearly even in Datafolha's simulated second rounds ^[7]. Suppose that means 50-50 and every one of the 20 points picks a side. Then Lula adds about 8 points and Bolsonaro about 12 ^[15]. On that reading, voters outside the two leaders lean to Bolsonaro by roughly three to two ^[16], and a four-point first-round lead ^[14] is worth little against that split.

Lula could still clear 50% if endorsements or late consolidation move enough of the 20 points. Both are on Crypto Briefing's list of things that could shift the race ^[6]. Failing that, he goes into a runoff with his four-point lead. Or Bolsonaro goes in with most of the 20 points leaning his way, as the simulations imply ^[16]. I think the second round is the base case, and I'd call it close to even. The counter-case comes from prediction markets, which Crypto Briefing says back Lula to win the most first-round votes ^[18]. That position is a bet on first place, and first place under 50% only sends Lula to the runoff ^[4].

The other market term is a puzzle. Crypto Briefing reports a reduced expectation that Bolsonaro takes between 36% and 39% ^[17]. Datafolha's 38% for him sits near the top of that bracket ^[3]. Lower odds on the range around his poll number mean traders put more weight on a finish either above 39% or below 36%. A Bolsonaro result above 39% would bring the first round close to the tie Semafor describes ^[1].

Semafor puts the stakes in diplomacy. The EU fears a Brasilia that pivots harder toward Washington ^[8]. Semafor also reported that Bolsonaro's brother has threatened any diplomats whom the family believe "sabotaged" their father's presidency ^[9].

Neither source reports prices for Brazil's currency, bonds or stocks, so the two cannot show how much of a runoff is already priced. For allocation, a near-even second round ^[7] argues against sizing a Brazil position to Sunday's count. On these polls, Sunday picks two finalists ^[4][1].
