What is Devils Heat?
The Polymarket ad campaign debuted less than 48 hours before Wednesday’s NFL regular-season opener. The matchup is a rematch of last season’s Super Bowl as the Seattle Seahawks host the AFC Champion New England Patriots.
Last February in Santa Clara, the Seahawks held the Patriots scoreless through three quarters en route to a 29-13 win. That said, the defending champions are not the favourites to win the Lombardi Trophy this year. Nearly every US operator has installed the Los Angeles Rams as the overwhelming choice to capture the title.
As of 6pm ET, the Seahawks had a 62% probability on Polymarket to defeat the Patriots in Wednesday’s opener. Conversely, Polymarket traders gave the Patriots a 39% chance to pull the upset. At those odds, a $100 contract on the Pats carries a payout of $247.35.

These internal changes form part of wider organisational shifts following Veikkaus’ May 2026 decision to establish two subsidiaries: one dedicated to exclusive operations and another for the newly competitive, licence-based market.
Veikkaus has submitted licence applications as a private entity, joining around 50 other companies that had applied to join the upcoming market by the end of June.
The company committed to a management reshuffle late last year as part of this transition, scrapping the role of deputy CEO after Velipekka Nummikoski was shuffled into a new role.
About Devils Heat
Marantelli says the London-based White Swan is a significant market maker on several secondary exchanges, accounting for as much as 40% of activity on some platforms. Its particular focus is the RFQ, parlay market.
“Just better margins,” he says of that decision. “I think it’s more defendable. It’s the area that fewer people can do well. So I think it’s more defendable margin, more ability to get long-term contracts and beneficial positions.”
Singles can be profitable, but parlay pricing requires the market maker to calculate the correlations between multiple outcomes and respond dynamically to individual requests. It is a skill set built over years in the sharper regions of the existing sports betting ecosystem.
