IG Group Secures Underdog Acquisition to Strengthen Position in US Prediction Markets

IG Group, the UK-based trading platform provider, has announced its acquisition of Underdog, a company specializing in prediction markets and daily fantasy sports, in a deal valued at up to $1.3 billion; the agreement includes $1.1 billion paid upfront along with an additional $200 million tied to earnout provisions. The transaction, which closed in the first half of 2026, positions IG Group to expand its footprint in the American market where prediction platforms continue to attract growing user bases.

Deal Structure and Financial Highlights

Financial details released alongside the announcement show Underdog generated $466 million in revenue over the twelve months ending June 30 while posting $46 million in EBITDA during the second quarter alone; these figures reflect sustained demand for daily fantasy sports alongside emerging prediction products. Observers note the earnout component allows both parties to align future performance incentives, particularly as Underdog scales into non-sports prediction categories such as entertainment events and political outcomes.

Strategic Impact on IG Group Operations

The acquisition is projected to double IG Group’s existing US revenue streams while substantially increasing its overall active user count; executives have indicated the combined entity will leverage Underdog’s technology stack to introduce new market categories beyond traditional sports betting. Data from the twelve-month period ending in June demonstrates Underdog’s ability to maintain high engagement levels, a factor that supports expectations for accelerated user growth once integration begins later this year.

According to filings referenced by analysts, the combined platform will retain Underdog’s brand identity in the short term while gradually introducing IG Group’s risk-management tools to support higher-volume trading activity; this phased approach aims to preserve user experience during the transition period. Those familiar with similar cross-border acquisitions point out that technology integration typically requires twelve to eighteen months before full synergies materialize.

Regulatory and Industry Context

US state gaming commissions in key jurisdictions have already issued statements confirming they will review the ownership change under existing licensing requirements, and the transaction structure complies with current interstate commerce guidelines governing fantasy sports operators. The National Council on Problem Gambling has published resources outlining best practices for prediction platforms, resources that IG Group has referenced in its post-acquisition compliance planning.

Academic researchers at teh University of Nevada, Las Vegas Center for Gaming Research have documented rising participation in prediction markets across demographic segments, findings that align with Underdog’s reported revenue trajectory and support the rationale behind IG Group’s investment decision. The acquisition also reflects broader consolidation trends within the sector as established trading firms seek to capture share in rapidly developing digital markets.

Conclusion

The IG Group and Underdog transaction marks a significant consolidation step within the prediction markets space, with the $1.3 billion valuation underscoring the financial scale now associated with daily fantasy and related products. Integration activities are scheduled to commence in the third quarter of 2026, and stakeholders will monitor user retention metrics as the combined platform rolls out expanded non-sports offerings. The deal’s earnout structure provides ongoing accountability for performance targets through 2028, ensuring continued focus on revenue growth and user engagement across both legacy and new market categories.
