Prediction markets had a particularly fruitful month of June, reaching a whopping $50 billion in trading volume, once again showing the ultra-fast growth of the sector amid major sporting events unfolding.
Kalshi on Top
According to data from Australian multinational investment bank Macquarie Group, which operates in over 34 global markets, Kalshi stood firm on its position as the industry’s dominant platform, accounting for an estimated $33 billion in trading volume.
The operator also managed to boost its market share from 57% in May to 65% in June.
The start of the 2026 FIFA World Cup, believes Macquarie analyst Chad Beynon, helped boost Kalshi hit the pedal to the medal, while a series of strategic partnerships also contributed to the platform’s momentum.
One example highlighted in the report was Kalshi’s partnership with ADI PredictStreet.
Over $500 Billion in Trading Volume
According to June’s activity report, Macquarie estimates the prediction market industry is operating at an annualized pace going over $500 billion in trading volume, with sports-related contracts accounting for about 50% of the activity.
The report also explained that rising trading volumes are making investors more interested in privately held prediction market companies.
Recent reports indicate Kalshi is pondering a new fundraising round that could value the company at around $40 billion, which is roughly double its most recent funding valuation.
The broader prediction market industry is also attracting attention from established betting companies.
DraftKings, which also recently recorded an impressive surge in activity courtesy of the World Cup, recently launched its DKeX exchange, further proving that sportsbooks and prediction markets are becoming increasingly intertwined.
Macquarie went on to explain that the ongoing growth in trading volumes is suggestive of prediction markets’ evolution beyond a niche product.
The Sydney-founded group claims that prediction markets are turning into a wider financial technology category with help from growing liquidity and rising participation from retail and institutional traders.
