AI trading bots execute trades in 0.01 seconds, outperforming humans in speed and consistency. However, research suggests that most retail traders using bots lose money, with UC Berkeley finding bots lost 77 times more money per user than human traders. On Polymarket, 37% of AI agents achieved positive returns, but humans picked correct outcomes more often.
