Each sub-question captures a correlated condition (candidate viability, scheduling, polling strength, legal eligibility) all driven by the same political momentum around Flávio and PL; their weighted average yields the probability PL officially nominates him before the deadline.

## Question
Will the Liberal Party officially nominate Flávio Bolsonaro as its candidate for president of Brazil before August 15, 2026?
## Description / Resolution Criteria
## Description
Flávio Bolsonaro, son of [far-right](https://www.dw.com/en/just-how-far-right-was-brazils-bolsonaro/a-64249379) former Brazilian president Jair Bolsonaro, has at the time of this question consistently been the top-[polling](https://en.wikipedia.org/wiki/Opinion_polling_for_the_2026_Brazilian_presidential_election#First_round_2) opposition candidate for the [2026 Brazilian presidential election](https://en.wikipedia.org/wiki/2026_Brazilian_general_election), which is scheduled to be held on October 4, 2026, with a runoff on October 25, 2026 if no candidate wins an outright majority. Jair Bolsonaro represented the [Liberal Party](https://en.wikipedia.org/wiki/Liberal_Party_\(Brazil,_2006\)#Notable_members) ( PL) when he was president, from 2019 to 2022.
In May 2026, a scandal [broke](https://www.theguardian.com/world/2026/may/14/flavio-bolsonaro-banker-film-jair-bolsonaro) in which a tape leaked of Flávio Bolsonaro asking a jailed banker to fund a documentary on his father. Since the revelations, Bolsonaro's polling numbers have [dipped](https://www.braziloffice.org/campaigns/view-campaign/d9_eBCeXNIUWxGUQHc0McI8qazwDaYOwO9pjJQi69vq3AvIoqcfm83Pi98LahyGNCpAbBvmpQ7I_FkOxyOBlB1iuQvWiyLfU), and there has been [speculation](https://valorinternational.globo.com/politics/news/2025/02/20/flavio-bolsonaro-admits-indictment-forces-candidate-shuffle-for-2026.ghtml) that PL may choose someone else as its presidential nominee.
`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 43984, "question_id": 44011}}`
## Resolution Criteria
This question resolves as **Yes** if, before August 15, 2026, the *Partido Liberal* (PL) or Liberal Party officially nominates Flávio Bolsonaro as its candidate for president in the [2026 Brazilian general election](https://en.wikipedia.org/wiki/2026_Brazilian_general_election).
## Fine Print
The question may resolve as **No** before August 15, 2026 if PL officially nominates someone else.
***
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/43984) which opened on 2026-06-12 09:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.
## Sub-question decomposition
- (w=0.40) Will Flávio Bolsonaro remain the intended/front-running PL presidential candidate (not withdraw or be replaced) through the nomination window? — The May 2026 scandal and indictment speculation create real risk PL pivots to another candidate; his continued standing
- (w=0.25) Will PL formally hold its nominating convention/decision before August 15, 2026? — Brazilian party conventions typically occur in late July/August; the nomination must be officially registered before the
- (w=0.20) Will Flávio Bolsonaro's polling hold up well enough that PL views him as their strongest opposition candidate? — Post-scandal polling dip could push PL toward an alternative (e.g., another Bolsonaro ally or a governor).
- (w=0.15) Will legal/eligibility issues (indictment, ineligibility rulings) avoid blocking Flávio's candidacy? — Legal disqualification risk, similar to what affected Jair Bolsonaro, could prevent his official nomination.

## Cross-Market Signals
### Polymarket
- "Will Brazil win the 2026 FIFA World Cup?" → Yes: 0.07, Volume: $44.4M
Information gaps:
- Exact date/deadline of PL's official nominating convention under Brazilian electoral law
- Post-May-2026 polling numbers showing magnitude of Flávio's dip
- Whether PL has formally floated alternatives (e.g. Tarcísio) as replacement
- Base rate: how often Brazilian parties replace front-runner before convention
Key uncertainties:
- Whether documentary/banker scandal forces PL to replace Flávio
- Legal/eligibility rulings on Flávio's indictment
- Timing of formal PL convention relative to Aug 15 deadline
- Whether Tarcísio or another candidate emerges as PL preference
## Required pre-forecast walkthrough
Before giving probabilities, walk through these explicitly:
(a) The time left until the question resolves.
(b) The status quo outcome — what happens if nothing changes from today.
(c) A brief scenario that results in NO.
(d) A brief scenario that results in YES.
## Calibration guidance
- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.

Jair Bolsonaro represented the [Liberal Party](https://en.wikipedia.org/wiki/Liberal_Party_\\(Brazil,_2006\\)#Notable_members) ( PL) when he was president, from 2019 to 2022.\n\nIn May 2026, a scandal [broke](https://www.theguardian.com/world/2026/may/14/flavio-bolsonaro-banker-film-jair-bolsonaro) in which a tape leaked of Fl\u00e1vio Bolsonaro asking a jailed banker to fund a documentary on his father. Since the revelations, Bolsonaro\u0027s polling numbers have [dipped](https://www.braziloffice.org/campaigns/view-campaign/d9_eBCeXNIUWxGUQHc0McI8qazwDaYOwO9pjJQi69vq3AvIoqcfm83Pi98LahyGNCpAbBvmpQ7I_FkOxyOBlB1iuQvWiyLfU), and there has been [speculation](https://valorinternational.globo.com/politics/news/2025/02/20/flavio-bolsonaro-admits-indictment-forces-candidate-shuffle-for-2026.ghtml) that PL may choose someone else as its presidential nominee.\n\n`{\"format\": \"metac_reveal_and_close_in_period\", \"info\": {\"post_id\": 43984, \"question_id\": 44011}}`\n\n## Resolution Criteria\nThis question resolves as **Yes** if, before August 15, 2026, the *Partido Liberal* (PL) or Liberal Party officially nominates Fl\u00e1vio Bolsonaro as its candidate for president in the [2026 Brazilian general election](https://en.wikipedia.org/wiki/2026_Brazilian_general_election).\n\n## Fine Print\nThe question may resolve as **No** before August 15, 2026 if PL officially nominates someone else.\n\n***\nThis question\u0027s information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/43984) which opened on 2026-06-12 09:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question\u0027s resolution could have been known before this question opened, then this question will be annulled.",
