Polymarket has algorithmic arbitrage and various mining methods, but what I prefer is the previous approach of Théo, who was ranked first in betting on Trump's presidential election. He claimed to be a French trader who worked at several investment banks. After Trump was elected president, his publicly disclosed position profits were between $50 million to $80 million, not including his positions elsewhere. He believed there were problems with mainstream American polling. Everyone said the same thing back then, but few actually did it themselves. He personally commissioned social surveys, especially neighborhood polls—"who do you think your neighbors/friends will vote for" in key swing states like Pennsylvania, Michigan, and Wisconsin. He conducted ground-level and customized surveys, ultimately obtaining data samples. At a time when AI wasn't yet widespread, he personally performed weighting and error correction, calculated confidence levels, and used old-school statistical techniques to finally go all-in, becoming his own insider trading operation. That's the true strategy for playing Polymarket. But once you become a real insider trader, the methodology can only be shared after success. Paradox, paradox.
