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.

A hearing before the Supreme Court would be the culmination of what has been the biggest sports betting-related development since PASPA. Perhaps no other issue has united gaming stakeholders from various companies, tribes, states and regulators.

Beginning with the US presidential elections in November 2024, when prediction markets catapulted into mainstream culture, their rise has been undeniable. Kalshi and Polymarket have seen their valuations balloon to $40 billion and $21 billion, respectively, and the majority of the top US bookmakers have scrambled to expand into the prediction space in various forms, either by building their own exchanges, acquiring existing ones or engaging in market-making.
