One of the main concerns is Bill 560/2025, which is currently making its way through the council. The proposal prohibits advertising by betting companies at events in the city of São Paulo. This applies to events organised by public or private entities, whether for-profit or non-profit.
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.

FanDuel remains the leading US sportsbook, while Flutter’s international businesses provide additional sources of growth. But that quality comes with high expectations.
Beynon describes Flutter as “the highest-quality online betting franchise globally”, with FanDuel’s leadership position providing “significant long-term value”. The problem is that the market is increasingly questioning how much future earnings growth can be generated from that position as the industry matures.
DraftKings is a different proposition. Its share price went from $43.30 on 18 September 2025, to $21.75 upon market closure last week. Beynon says it “arguably offers the greatest operational upside if it can continue converting strong customer growth into sustained profitability”. Its prediction market strategy could also become an advantage if the new market proves complementary to sportsbook betting.

The web of lawsuits and court rulings involving prediction markets has greatly complicated the issue of jurisdiction. Kalshi has been forced to limit trading in multiple states, most notably Nevada, and the CFTC has gone to unprecedented lengths to protect its licencees. This includes suing nine states directly and issuing emergency orders to reject state mandates.
CFTC Chairman Michael Selig is currently the lone sitting commissioner for an agency that traditionally features a bipartisan group of five. Selig has repeatedly defended both the legitimacy of prediction markets as financial assets and the role of the CFTC in overseeing them. The CFTC under his direction has embarked on a series of rule proposals regarding prediction markets, although detractors argue that the proposed changes still allow for sports contracts and in some ways could be seen as a tightening of the belt to make a Supreme Court review look more favourable.
“It’s not a question of whether innovations like blockchain, artificial intelligence, and prediction markets will transform our markets. It’s a question of where this innovation will take place and who will write the rules,” Selig said during a meeting of the CFTC’s Innovation Advisory Committee on 20 August, which featured the CEOs of Kalshi, Polymarket, DraftKings, CME Group and more.
