70% of Polymarket Traders Lost Money as Top 0.04% Captured Most Profits: Data

Among over 1.7 million trading addresses on Polymarket, approximately 70% have realized losses while just 30% turned a profit, according to data from blockchain analyst DeFi Oasis.

The findings reveal stark concentration at the top, with fewer than 0.04% of addresses capturing over 70% of total realized profits, a collective $3.7 billion.

The analysis examined transaction data to calculate realized profit and loss across Polymarket’s user base.

Most profitable traders earned modest returns between $0 and $1,000, representing 24.56% of all addresses but capturing just 0.86% of total profits.

Earning more than $1,000 required ranking in the top 4.9% of participants.

Extreme Profit Concentration Mirrors Traditional Markets

The data shows 668 addresses with profits exceeding $1 million accounted for 71% of all realized gains, while just 2,551 traders earned between $100,000 and $1 million.

At the other end, over 1.1 million addresses, 63.5% of the total, recorded losses between $0 and $1,000, though 149 addresses lost more than $1 million each.

DeFi Oasis noted the calculation method tracks total sale proceeds plus redemption amounts minus purchase costs, excluding unrealized gains or losses.

Traders holding large open positions may show significantly negative realized returns despite potential paper profits.

The skewed distribution reflects broader patterns in prediction markets, where professional traders and sophisticated algorithms typically extract value from retail participants.

This revelation came at a time when Polymarket is facing scrutiny over potential conflicts of interest as platforms, including Crypto.com and Kalshi, build internal market-making desks that trade directly against users.

Platform Growth Continues Despite Concentration Concerns

Polymarket has maintained momentum despite the lopsided profit distribution, with monthly active traders approaching 462,600 and volumes surging past previous records.

The platform completed beta testing for its US relaunch in November after three years offshore following a $1.4 million CFTC settlement in 2022.

Founder Shayne Coplan, now a self-made billionaire at 27, recently participated in a regulatory roundtable convened by the SEC and CFTC.

The platform’s post-money valuation has climbed to $9 billion following significant investments, including a $2 billion commitment from Intercontinental Exchange, owner of the New York Stock Exchange.

Ethereum co-founder Vitalik Buterin recently defended prediction markets against critics who view betting on real-world events as morally questionable.

He argued these platforms offer superior truth-seeking mechanisms compared to social media, where sensationalism faces no accountability.

Buterin noted that financial stakes enforce accuracy, with prices bounded between 0 and 1, reducing the reflexivity effects common in traditional markets.

The defense sparked a heated debate with Quilibrium founder Cassie Heart, who questioned the ethics of profiting from potential deaths and disasters.

Heart suggested prediction markets on catastrophic events explain mainstream hostility toward crypto, though Buterin maintained that stock markets pose similar moral hazards through short positions.

Competition Intensifies as Major Exchanges Enter Space

Google Finance integrated live data from Polymarket and Kalshi in November, surfacing market probabilities directly in search results.

The feature allows users to query future events and track how odds shift over time alongside changes in historical sentiment.

FanDuel launched its FanDuel Predicts platform in December through a partnership with CME Group, offering event contracts on crypto prices, commodities, and economic indicators.

Coinbase filed lawsuits against Michigan, Illinois, and Connecticut in December, challenging state authority over prediction markets ahead of its January 2026 launch with Kalshi.

The rapid mainstream adoption continues despite regulatory uncertainty.

Combined trading volume across major platforms reached $44 billion in 2024, with on-chain prediction markets climbing from under $100 million monthly in early 2024 to more than $13 billion. Kalshi raised $300 million at a $5 billion valuation.

The concentration data arrives as prediction markets cement their role in retail trading cycles, though the findings suggest most participants subsidize profits for a tiny elite.

As it stands now, whether regulatory clarity and institutional entry will improve outcomes for retail traders remains uncertain.
