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.
What is Golden Grimoire?
When Spain captain Rodri lifted the Fifa World Cup trophy at MetLife Stadium in New Jersey in July, a nation celebrated its team’s return to the summit of world football. Across five weeks and eight matches, Spain had proved itself the best team on the planet, overcoming its strongest rivals to claim the trophy for a second time.
As Spain celebrated the successful end of their campaign, Kambi was reflecting on a significant achievement of its own. For the sports betting technology provider, the tournament represented a major technological milestone: its first World Cup traded entirely by AI.
Across 104 matches and more than 100 million bets, AI handled every stage of the pricing lifecycle – from ingesting data and creating the offering to managing liabilities and settling bets. The platform recorded zero downtime, delivered an operator trading margin of 18% and, during the final alone, processed more than one million unique bet combinations.

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.
MGM Resorts International’s investment case is supported by Las Vegas, regional casinos, property assets and its 50% interest in BetMGM. Its own share price has been on a different journey to its online pureplay peers, having increased by 5% in a year, to $37.81 on 18 September.
