What is Shamrock Quest?

The competition between prediction markets and sportsbooks is intense and there is some evidence that the former is encroaching on the latter’s customer base.

A survey by Fullstory, a behavioral data analytics company, says that amid the evolution of yes/no exchanges, 60% of bettors said prediction markets are altering how they use sportsbooks with 35% admitting that they’ve reduced usage of traditional sports wagering platforms as access to sports event contracts increased.

“Consumers are being presented with more options for how they can participate in online gaming, creating a more competitive landscape where a seamless digital experience is increasingly becoming part of the value proposition,” said Jason Wolf, president of Fullstory, in a statement. “The brands that understand how consumers are navigating, comparing, and engaging with their platforms in real-time can identify where friction is getting in the way of trust and retention.”

The problem is that many of these recommendations involve companies that are not authorised to operate in Brazil. Some may be licensed in other countries, but that doesn’t allow them to operate legally in the Brazilian market.

The research also found profiles of influencers known as tipsters, sports traders and “professional gamblers”. They sell access to groups, predictions, spreadsheets and other products related to betting, while presenting gambling as an income-generating activity.

According to The Intercept, some content even uses expressions like “leaving the CLT [Brazilian labour law]” and “your dream income” to promote this type of activity. There are also screenshots of alleged user earnings and posts that present gambling as a kind of investment.

The lesson is simple: gambling still attracts capital when the money is visible. It is less attractive when the payoff lies far in the distance.

The biggest new uncertainty in US sports betting is prediction markets. The American Gaming Association estimates that Americans will legally wager $29.5 billion in betting handle through US regulated commercial sportsbooks during the 2026 NFL season, broadly unchanged from the $29.4 billion handle recorded in 2025. These figures refer to the amount wagered, not sportsbook revenue.

Robinson calls prediction markets “the main event”. His argument is not simply that US customers are moving from sportsbooks to prediction markets. The more important point is that sportsbooks no longer have the relatively protected market that was once assumed.
