Wild Overlords

How to play Wild Overlords

Strip away the language of contracts, order books and event trading and Bernard Marantelli has a blunt description of what is happening inside US sports prediction markets. “Kalshi is a sportsbook that’s just not allowed to have an in-house risk team,” says the founder of White Swan Data, one of the specialist firms now making markets on prediction exchanges.

The difference is all about the risk function. A sportsbook employs traders to price bets and manage its exposure. An exchange provides an API through which firms compete to quote prices and supply liquidity.

“Here’s an API. Bernard and 88 other people can market-make all these request-for-quotes (RFQs),” Marantelli says. “Some people might come in and just do esports because they’re esports experts. Others do everything. Some focus on same-game parlays. But it’s a sportsbook.”

About Wild Overlords

In a separate case, the ASA examined display advertising for White Hat Gaming’s Casimba and The Grand Ivy Casino brands, which had appeared on HLTV.org – a specialist Counter-Strike 2 e-sports website – in March 2026.

Two banner ads promoted a “100% match bonus up to £100 on 1st deposit” and displayed the mandatory 18+ logo. The ads appeared alongside live match coverage featuring betting odds and sponsor logos, including a link to Casimba’s website. 

A complaint suggested that such placements were inappropriately targeted at under-18s.

What is Wild Overlords?

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.
