description: "The business model of Polymarket/Kalshi is extremely simple, with no technical barrier. As long as you have money, you can find someone like Claude to develop it…The biggest core barriers are: compliance + liquidity + capital + risk control + brand.These two platforms charge a 0.5%-1.2% commission, almost lying back and earning millions of dollars every day.The core: They profit from human nature:Because most retail investors are overconfident, greedy for stability, and crave short-term gratification (what we often call dopamine). They self-brainwash and are unwilling to admit they are gambling. As long as human nature doesn't change, retail investors will keep pouring in endlessly,and the platforms will keep lying back and earning commissions, a guaranteed profit with no loss.As long as you play on the platform long-term, even if your win rate is below 60%, you are highly likely to lose money!"
