Some traders invested $300,000 in prediction market platforms and ultimately only made a profit of $1,300. This case is quite interesting—behind the seemingly modest gains, there may be a hidden "last-minute" trading strategy. These players often precisely grasp market critical points, using minimal capital fluctuations to leverage returns. Although the return on investment may not seem large in terms of numbers, this operational approach suggests that traders might have mastered a near-risk-free arbitrage logic. The mechanism of prediction markets indeed provides fertile ground for such strategies to survive.
