Slightly reducing as I am influenced by other forecasters here, but with almost 4 years till the resolution, I feel that I do not know enough to go closer to the 0%. There seem to be too many things which can surprise me during that time.
During my search for new signals I found this article "AI-designed pandemic is not science fiction" by Lotti Tajouri, a quote from it:
"Four steps towards proactive prevention
At present, most safeguards are reactive – we mobilise after a threat appears. That approach will fail if future biological risks are complex, fast-moving, and deliberately engineered for disruption. What is needed is proactive prevention.
First, governments must take the dual-use risks of AI-enabled biotechnology seriously and resource them accordingly. Dedicated, multidisciplinary research teams should anticipate and model worst-case biological threats.
Second, international cooperation is essential. Pathogens do not respect borders, and neither does data. Biosecurity requires shared standards, shared intelligence, and shared responsibility.
Third, we must accept a paradox: AI is part of the problem, but it is also part of the solution. The complexity created by AI-driven biological design is beyond human comprehension alone. Counter-AI systems will be needed to detect patterns, anticipate risks, and support rapid defensive responses.
Finally, public discussion must mature. Acknowledging hypothetical threats is not fearmongering, it is risk management.
As a scientist and parent, I find the thought that powerful biological tools could fall into the wrong hands deeply unsettling.
It is naive to assume that technological progress will always be used responsibly because history tells us otherwise."
Why do you think you're right?
Last time he received 88% of votes cast, but that was when the opposition was boycotting the elections for unfair treatment. In the 2016 Elections he got 64% and was accused of rigging the poll, and now the opposition seem to be organized into at least two multi-party groups (see this article and this article) and there is also a parliamentary opposition (parties that were not delegalized or banned from the last parliamentary elections), so the opposition seem to be not as united as I initially thought.
The second article from 01/06/2025 says (translated using deepl.com):
"Congo-Brazzaville: Opposition forms new alliance ahead of 2026 presidential election
At least eight Congolese opposition parties, including Clément Miérassa's Congolese Social Democratic Party (PSDC), Jean-Jacques Serge Yhomby Opango's Rally for Democracy and Development (RDD), Dave Mafoula's Souverainistes, and Mabio Mavoungu Zinga's Alliance, announced on Saturday, May 31, that they had joined forces in a new alliance: the Rally of Forces for Change (RFC). Their ambition is to lead the Congolese people to change in 2026. "
Another article mentions some groups resigning from elections because of government not implementing biometrics and their refusal to establish consensual electoral register:

Worth noting what FreedomHouse writes about Republic of Congo:
https://freedomhouse.org/country/republic-congo/freedom-world/2025
"President Denis Sassou Nguesso has maintained nearly uninterrupted power for over 40 years by severely repressing the opposition. Corruption and decades of political instability have contributed to poor economic performance and high levels of poverty. Abuses by security forces are frequently reported and rarely investigated. While a variety of media operate, independent coverage is limited by widespread self-censorship and the influence of owners allied with the government. Human rights– and governance-related nongovernmental organizations (NGOs) scrutinize state abuses, but also self-censor to avoid reprisals."
For me it looks like a situation where the government can use all the dirty tricks to stay in power, so I would be surprised if they would be able to remove him and replace him with an opposition candidate winning elections this time.
Why might you be wrong?
I may miss something because I am new to this subject and only read about it for maybe two or three hours. Without reliable opinion polling and media freedom it is harder to know what is happening there, what are the attitudes of the people on the streets.
