An investor who "guesses" Polymarket with 99% accuracy — and no one understands how



On Polymarket, there is an active discussion about an investor who claims to predict the outcomes of events with an accuracy of about 99%. He talks about automation and data work. Thanks to the algorithms he has developed, he is able to predict the market. Is this possible in practice, or is he not telling us everything?

According to him, he has already earned about 20,000 euros on the platform in the last two days. The series of trades appears to be almost error-free, and the risk of failure is said to be minimal compared to most Polymarket users.



While it is impossible to confirm the accuracy of these figures without independent statistics, the stability of the results and the absence of public errors have made this investor one of the most talked-about figures in the market.
