Polymarket, a prediction‑market platform, recently revealed that more than half of its so‑called “long‑shot” bets on military action paid off. The data, shared in a blog post, shows that traders who copy the most active wallets earned outsized returns, sparking debate over the site’s copy‑trading model and the influence of a small group of users.

Kalshi, Polymarket’s chief rival, has pushed a stricter stance, banning “violent markets” such as war and kidnapping while still allowing betting on the Strait of Hormuz. The company also demands proof of identity, contrasting sharply with Polymarket’s anonymous cryptocurrency payments and lack of KYC for most international users.

Financial‑data firm Unusual Whales sells a $20‑a‑month tool that flags unusual bets on Polymarket, while Polywhaler offers real‑time monitoring for $4.99 a month. Polymarket’s own list of the ten most‑copied wallets supplies traders with strategy tips and cautionary notes, illustrating how copy‑trading can amplify gains for a select few.

A recent London School of Economics study found that only 3 percent of accounts drive price discovery, proving that a small informed minority shapes outcomes while the majority merely fuels volume. This dynamic explains why Polymarket’s high‑paying bets attract attention, but also underscores the risk for most users who may end up subsidizing expert traders.
