New blockchain data reveals stark profitability patterns on decentralized prediction market Polymarket.
Only 30% of the platform's 1.7 million trading addresses have realized profits.
The remaining 70% show realized losses, according to data from blockchain analytics account defioasis.
What Happened
The analysis examined realized profit and loss across Polymarket's entire trading history.
Fewer than 0.04% of addresses captured more than 70% of all realized profits on the platform.
These top addresses cumulatively realized profits totaling $3.7 billion.
Most profitable addresses earned modest amounts between $0 and $1,000.
This group accounts for 24.56% of all addresses but captures only 0.86% of total realized profits.
Earning more than $1,000 in realized profits places a trader in the top 4.9%.
On the losing side, approximately 1.1 million addresses - representing 63.5% of all users - have realized losses between $0 and $1,000.
More than 140 addresses have realized losses exceeding $1 million.
The calculation method used total sale proceeds plus total redemption remittances minus total purchase costs.
This approach does not account for unrealized gains or losses on open positions.

Why It Matters
The data mirrors traditional financial markets where a small fraction of sophisticated traders consistently outperform.
Recent research covering 86 million on-chain transactions identified six profitable strategies: information arbitrage, cross-platform arbitrage, high-probability bond strategies, liquidity provision, domain specialization, and speed trading.
Professional traders using these approaches achieved returns exceeding most hedge funds.
The concentration of profits suggests prediction markets reward systematic approaches over intuition.
Polymarket processed over $9 billion in trading volume throughout 2025.
The platform recently received regulatory approval to return to the U.S. market after a multi-year compliance overhaul.
