Polymarket's prediction market is seeing a concentration of profits among bots and large investors, leaving few regular users with consistent gains. To be in the top 0.51% of profit and loss, users need to earn over $1,000, while a trading volume of more than $50,000 is required to rank in the top 1.74%. Sophisticated traders employ strategies like the 'Endgame Sweep' and arbitrage in multi-outcome markets to secure small, steady profits. In contrast, everyday users often face losses due to slower execution and market manipulation by larger players.
