About Book Of Monsters

The total cost of the ad has not been divulged by Polymarket, but it is fair to estimate that it fell in the millions given the high expenses of bringing aboard a prominent filmmaker such as Berg. Beyond director fees, Polymarket also had to budget for agency and concept fees, set construction and post-production costs that include visual effects, licensing and sound design. In late-August, Polymarket disclosed that it has sought a $21 billion valuation in a new funding round led by Donald Trump Jr’s venture firm, 1789 Capital.

Polymarket may defend any substantial investment in marketing given the overwhelming impact on customer acquisition that ensued. On Tuesday, Polymarket ranked first on the App Store in downloads for free finance apps, topping archrival Kalshi, Capital One Mobile and prominent payment providers PayPal and Venmo.

The company did not immediately respond to a request for comment from iGB.
