This new article from WSJ is very explosive

On Polymarket, there are 1.6 million active accounts, with only 0.1% of accounts (less than 2,000) taking 67% of all profits
Over 70% of users lose money, with typical users losing $1-$100, and the worst 10% averaging a loss of $4,000
Who are the top 0.1% making money? They found a few:
1. Michael Boss, former professional poker player with a background in statistics. Making 60 trades per minute, updating quotes 30 times per second, earning $668k in three months
2. Samuel Wood-Soloff, dropped out of Princeton, deployed $500k solely as a market maker
3. Jonathan Stall-Ryan and his college student partner, algorithmic flow, executing tens of thousands of trades daily, turning $1,000 into millions
Most are earning small, certain profits, relying on high-frequency to accumulate little by little; only insiders can truly win at pure gambling
