How to play Volcano
The bill prohibits signs, banners, or display panels in arenas, gymnasiums, stadiums and other sports event venues. It also bans advertising on public transport, such as the side panel, exterior or the rear window of buses. The bill imposes a fine of BRL50,000 ($10,000) and a ban on hosting events for up to two years.
The proposal does not explicitly prohibit the display of betting brands on team jerseys, but some city councillors want to include this in the bill.
Clubs fear the measure will jeopardise revenue from betting company sponsorships. Corinthians (Esportes da Sorte), Palmeiras (Sportingbet), and São Paulo (Superbet) alone hold contracts worth BRL350 million annually with betting firms.
What is Volcano?
Yahoo said Polymarket is still an advertising partner and suggested the two could collaborate on other projects in the future. Polymarket has not provided any public explanation for the end of the data partnership.
The news comes as prediction market operators continue to form alliances with major media outlets. These deals allow news outlets to embed event contract data into their reporting and offer prediction platforms more visibility to investors and news audiences.
Polymarket has developed its media presence elsewhere. In January, it signed a deal with Dow Jones to provide its prediction market data to several of the publisher’s consumer platforms. The deal covers publications including The Wall Street Journal, Barron’s, MarketWatch and Investor’s Business Daily.
About Volcano
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.
