The names at the top hold when the count leaves the United States.
In September, prediction markets took 33.9% of US iGaming demand on Blask Index, counted together with traditional brands. Blask follows the segment in 41 countries, and that month the first three brands sat in the same order there as in the United States.
Polymarket and Kalshi still lead the July–September ranking, and both lost about half their July search by September. Novig moved the other way: a campaign with Sydney Sweeney went live on 9 September, and search rose about fortyfold from a July base far below either leader, enough to take third for the quarter.
The US quarter has the same three names and the same shape, with both leaders lower in September than in July and Novig up into third.
After that the lists diverge. Myriad is fourth in the United States and fifth on the wider sum, Manifold takes the other side of the swap, and ProphetX closes the US ten with no demand outside the country. ADI PredictStreet, sixth on that wider sum and the World Cup’s prediction-market partner, is a July name and does not make the US ten.
The likeness is the weight of the United States, which still holds most prediction market demand. Polymarket is the brand that leads abroad. Kalshi’s second place and Novig’s new third are American moves large enough to set the wider ranking.
