What is Hammerfall?
During the livestream, the president stated that he had spoken with a woman who said her 26-year-old son had taken his own life because of online betting. He also mentioned hearing from a bettor who had racked up BRL2 million ($388,410) in debt in just three months of wagering.
Lula said he intends to discuss the matter with his team and analyse potential measures to consider the social impact of online betting.
What the president does not acknowledge is that the government relies on revenue from the sector. In just the first seven months of 2026, BRL8.747 billion generated by sports betting has already flowed into public coffers. The Federal Revenue Service estimates the total could reach BRL16 billion by the end of the year. In 2025, nearly BRL9 billion was collected from sportsbooks.
About Hammerfall
It’s widely believed that all-or-nothing exchanges are carving out significant niches in states, such as California and Texas, where sports betting is prohibited, but there’s also emerging consensus that the prediction market threat to sportsbooks is easing.
A major advantage for traditional sportsbook operators is their ability to aggressively fund customer acquisition and retention bonuses. As EKG points out, prediction markets have “less ability to be generous with bonuses” because users trade against one another rather than against the house.
That creates a stark contrast during peak football season when traditional sportsbooks spend heavily on promotions. Offers ranging from $350 to $365 from major operators make the $25 to $50 promotional matches typically seen on prediction markets appear modest by comparison.
How to play Hammerfall
Joey Feazel, head of football at Caesars Sportsbook, told Casino.org that favorites, Overs, and anytime touchdown scorers combined to create a bettor-friendly trifecta. Bettors only faced major resistance when the Los Angeles Chargers were upset by the Arizona Cardinals.
However, LSR noted that traditional game outcomes are no longer reliable indicators of bookmaker profitability, largely due to the rapid growth of same-game parlays and player props.
In the Las Vegas-based Circa Survivor contest, which drew over 25,000 entries entering Week 1, more than 8,000 entries were eliminated in the opening slate—most knocked out when the 8.5-point favorite Chargers fell to the Cardinals. That upset served as a proxy for the wider market, ruining countess parlay tickets across major sportsbooks.
