Underdog, the US daily fantasy sports and prediction market operator, posted revenue growth of 100% year on year in the third quarter of 2026, according to figures disclosed by FTSE 100 acquirer IG Group ahead of deal completion.
IG Group reported the numbers alongside a decline in its own Q3 performance, a contrast that sharpens the strategic logic behind the acquisition. IG has not named a closing date, but investor briefings on the transaction are expected to follow the disclosure.
Underdog operates both a daily fantasy sports product and a prediction market platform, placing it directly in the contested territory that state regulators and the CFTC have been fighting over through 2026. Its revenue trajectory will draw attention from that audience as much as from financial markets.
IG Group's entry into US prediction markets via acquisition, rather than organic build, reflects the cost and complexity of obtaining the necessary regulatory relationships from a standing start. Whether Underdog's growth rate holds through a period of heightened enforcement scrutiny is the operational question IG's investors will be pricing from here.
