IG Group acquires Underdog for $1.3B to expand US prediction markets

IG Group, the London-based financial trading platform, is paying $1.3 billion to acquire Underdog, a US-based prediction market operator. The deal, announced in late July, represents a significant bet by an established financial services company on a sector that has been gaining momentum among retail investors and traders seeking exposure to unconventional assets.

Prediction markets allow participants to buy and sell contracts tied to the outcomes of future events—elections, sports competitions, economic indicators, and other occurrences with uncertain results. Underdog has built a platform that lets users trade on these outcomes, tapping into what appears to be a growing appetite among American investors for alternatives to traditional stock and bond trading. The company has attracted a user base willing to engage with this newer form of speculation and investment.

IG Group's move signals confidence that prediction markets represent a durable business opportunity in the United States. The company, which has long operated in derivatives and spread betting in Europe and other markets, is now positioning itself to capture a share of American retail trading activity as it shifts toward these emerging asset classes. The $1.3 billion price tag reflects the perceived value of Underdog's user base, technology platform, and market position.

The acquisition arrives at a moment when prediction markets have begun to shed some of their earlier regulatory uncertainty. As clarity has emerged around how these platforms operate within US law, traditional financial firms have grown more comfortable entering the space. What was once a niche corner of the trading world is becoming a recognized sector that institutional players believe warrants serious capital investment.

Underdog's appeal lies partly in its ability to democratize access to prediction markets. Rather than requiring the kind of sophisticated infrastructure or regulatory relationships that might have been necessary in earlier years, the platform offers a consumer-friendly interface that lets ordinary traders participate. This accessibility has helped build the user engagement that makes the company valuable to a buyer like IG Group.

The deal also reflects a broader shift in how financial services companies think about growth. Rather than relying solely on traditional equity and fixed-income products, firms are increasingly looking to alternative trading venues and asset classes to attract and retain customers. Prediction markets fit that profile—they offer novelty, engagement, and the potential for significant trading volume if adoption continues to accelerate.

For IG Group, the acquisition provides immediate scale in a market where it previously had no presence. The company gains Underdog's existing user base, operational infrastructure, and regulatory relationships in the US. It also positions IG Group to benefit from whatever growth trajectory prediction markets follow over the next several years. Whether that growth materializes depends partly on continued regulatory acceptance and partly on whether retail traders sustain their interest in these products as novelty wears off.

The transaction is expected to close subject to customary regulatory approvals and closing conditions. Once complete, Underdog will operate as part of IG Group's US operations, though it may retain its brand identity to preserve the user loyalty it has built. The deal underscores how seriously major financial firms now view prediction markets as a legitimate and potentially lucrative segment of the broader trading ecosystem.
