Review: IG's Underdog deal is a layered wager, not a $1.3bn cheque

iGaming Business has published a sharp analysis of IG Group's $1.3bn acquisition of Underdog Sports, and it is worth reading precisely because it refuses to take the headline number at face value. The piece unpicks the deal's structure, separating the upfront payment from the earn-out and the much larger management incentive plan, and shows how much of the 'expensive' part of the deal is contingent on Underdog hitting steep future EBITDA targets. It also grounds the valuation in a comparison to PrizePicks and notes that IG's shares fell around 20% after the announcement, a useful reminder that the market has not fully bought management's story.

The piece's real contribution is framing the acquisition as a layered wager rather than a single bet on prediction markets. It ties the price directly to US regulatory risk, arguing that the deal structure hedges against the possibility that sports contracts on regulated venues get reclassified as gambling. It also surfaces the personal dimension: IG's CEO previously bought the founder's first DFS business and later invested personally in Underdog, a history that cuts both ways in assessing whether the buyer knows what it is getting. Expert voices, including Corfai's Ben Robinson and H2's Ed Birkin, sharpen the debate without settling it.

Why this matters now is clear. Prediction markets have moved from curiosity to strategic battlefield, with DraftKings, FanDuel and Fanatics all positioning themselves in different ways. The piece asks the question that will define the category: are prediction markets creating genuinely new revenue or just cannibalising DFS spend? It also highlights the emerging split between owning exchange liquidity and owning the customer, which will shape whether this ends up a winner-take-most market or a fragmented one. For operators and investors, the stakes are less the $1.3bn headline than what the MIP thresholds say about Underdog's required growth trajectory.

As Robinson puts it, "The really expensive part of IG's package is therefore a long way out." That is the cleanest summary of the deal's risk profile. The piece is thorough, well-sourced and leaves the reader with a more sophisticated understanding of what IG is actually buying, and what could still go wrong.
