Bernstein projects the category could reach $240 billion in annual volume this year.

Retail Behavior Shapes the Prediction Markets’ Landscape

In Q1 2026, 82.3% of Polymarket users traded under $10,000 across the entire quarter. Only 2.5% of users crossed the $100,000 mark during that period.

The average micro user traded just $35, and the average light user reached $392. These numbers confirm that small traders, not institutions, are currently defining this market.

Crypto served as the primary entry point for new users entering the space. It accounted for 39.6% of activity among the smallest traders on Polymarket.

Bitcoin alone drew 593,000 users and $5.42 billion in trading volume in Q1. The median Bitcoin trade stood at just $3.16, placing the barrier to entry at nearly zero.

As users became more active, their behavior shifted notably. They did not increase individual trade sizes; instead, they traded across more categories.

Micro users averaged 2.5 active days and 1.45 categories, while mid-tier users reached 9.9 active days and over 2.3 categories. Broader exploration, not bigger bets, drove deeper engagement throughout the quarter.

Bitget Wallet shared these findings in a post on X, noting that prediction markets now resemble a consumer app more than a financial product.

The firm also noted that crypto’s share of activity gradually fell to 36.8% among mid-tier traders. It remains the most effective onboarding tool in the category. However, it is not what retains users over the long term.

Sports and Category Frequency Fuel Long-Term Engagement

Sports emerged as the largest category on Polymarket in Q1, generating $10.1 billion in volume. Participation in sports markets rose from 22.7% among micro users to 29.2% among mid-tier users.

A 45% surge in March was driven by the NBA season and NCAA March Madness. The NBA alone attracted 300,000 users and $3.11 billion in trading volume.

European football leagues also drew substantial international participation during the quarter. The English Premier League generated $540 million, the Champions League contributed $448 million, and La Liga added $368 million.

NCAA Basketball produced $900 million in volume. These figures show that sports markets have a truly global audience.

Esports performed well above expectations within the sports category. League of Legends generated $657 million, CS2 added $536 million, and Dota 2 contributed $209 million.

Together, those three titles produced roughly $1.47 billion in Q1. Median bet sizes in esports ran between $6 and $9, higher than in most traditional sports.

Frequency of engagement proved to be a key retention driver across all categories. Weather markets surged 263% in March, led by daily temperature forecast predictions.

Crypto markets generated $7.3 billion in Q1, rising 55% as an always-on trading environment. Categories with built-in recurrence consistently showed stronger user return rates across the quarter.
