Bloomberg: Prediction Market Traders "Hit the Streets" to Survey US Voters, Racing for an Information Edge in the Midterms

Odaily: As the US midterm elections approach, a group of seasoned traders on Kalshi and Polymarket have begun seeking trading advantages through on-the-ground "street-walking" fieldwork and voter data analysis. Among them: former Democratic National Committee (DNC) economics professor and election model analyst Douglas Campbell, who goes by the username AlexanderHam on Kalshi, has accumulated over $800,000 in profits, ranking as the platform's sixth most profitable election trader; another trader, David Bensoussan, is primarily active on Polymarket, where under the username Scottilicious he has accumulated over $1.5 million in profits, with a position of more than $280,000 betting on Democrats winning the House, a market whose probability has now risen to approximately 94%.

Analysts suggest that some traders are seeking information advantages through fieldwork, which has raised concerns about information asymmetry and insider trading. Polymarket this week has launched an investigation into suspicious trading during the Israeli election period. (Bloomberg)
