Opinion Prediction Market Thwarts Kalshi And Polymarket With $1.5 Billion Weekly Volume

What Happened

Opinion.Trade has posted one of the strongest launches in prediction market history, seizing a 40.4% weekly market share and $1.5 billion in volume just weeks after going live on BNB Chain.

With this, it surpassed $3.1 billion in cumulative trading, marking the strongest launch since April 2024. During the same period, open interest hit $60.9 million, already ranking third industry-wide behind Kalshi ($302.1 million) and Polymarket ($250.5 million).

Transaction peaks aligned with major crypto-native markets, particularly those tied to Monad’s TGE date, launch FDV, and BNB pricing, with Opinion consistently outperforming competitors.

During its launch window, the chain processed more than 71,000 Opinion transactions on peak days without noticeable degradation. This is a crucial requirement for prediction markets, where timely order execution defines the user experience.

Market Context

The platform’s rapid ascent now positions it as a credible third major player alongside Polymarket and Kalshi.

Opinion Captures 40% of Prediction Market Share With $1.5 Billion Weekly Volume

According to Messari researcher 0xWeiler, Opinion.Trade averaged $132.5 million in daily notional volume between October 24 and November 17.

The breakthrough occurred between November 11 and 17, when Opinion led the entire sector with $1.5 billion in weekly notional volume, capturing 40.4% of all trading.

For context, Kalshi held 32.9%, and Polymarket followed with 26.6%, marking only the third time any platform aside from those two dominated a seven-day span.

Why Opinion Captured Market Share So Quickly

However, the clearest growth engine is its OPN Points program, which rewards users for providing liquidity, placing high-quality trades, and maintaining open positions.

With eligibility starting at just $200 in weekly trading volume, participation is accessible and heavily incentivized, a key factor in Opinion’s early dominance before token issuance.

Metapool (a planned liquidity layer to merge fragmented event markets)

Opinion Protocol (a forthcoming cross-market token standard)

Opinion AI automatically converts user prompts into structured prediction contracts and proposes market resolutions using a multi-model jury that includes OpenAI, Claude, and Gemini.

Why It Matters

A combination of structural and strategic advantages drove Opinion’s breakout. The project is backed by YZi Labs (formerly Binance Labs), a major signal of credibility given the firm’s $10 billion portfolio.

Details

User activity reflected the surge. Opinion averaged 25,300 daily transactions and registered more than 62,400 unique users in its first three weeks.

Opinion also raised a $5 million seed round in March 2025, led by YZi Labs and Animoca Ventures.

Opinion’s AI-driven architecture also distinguishes it from rivals. Its four-layer stack includes:
