最新报道:On Polymarket, sharp traders are securing risk-free profits by exploiting mispriced odds and lightning-fast arbitrage strategies, such as buying all outcomes when their combined prices total less than $1 for guaranteed returns, with a veteran noting that a 0.5% risk-free return can yield astonishing annualized gains at scale. Automated bots dominate these fleeting opportunities, while strategies like the "Endgame Sweep" target near-certain outcomes priced between $0.95 and $0.99, though they carry "black swan" risks from sudden event reversals. Arbitrageurs also act as market makers, rebalancing odds and improving liquidity, with liquidity providers earning over $20 million in the past year, as the platform's expansion intensifies competition in decentralized prediction markets.
