What is Big Sumo?

“It has to translate into practical action, educating players, engaging communities, protecting young people and highlighting the dangers of illegal and unlicensed gambling.”

Africa’s Safer Gambling Week will be held annually, although Kesitilwe stresses player protection should be viewed through a daily lens.

“We want Africa Safer Gambling Week to create a platform for ongoing cooperation,” he adds.

In 2025, Brazil collected almost BRL10 billion ($1.97 billion) in tax revenue from the licensed sector. In the first seven months of this year alone, BRL8.7 billion generated by the activity was delivered to public coffers. The Federal Revenue Service itself estimates that the sector should reach BRL16 billion in revenue during 2026.

Besides revenue collection, another concern is legal and economic. Companies have paid over BRL2.5 billion for licences since the sector’s regulation. Certainly, the end of the activity would lead to litigation to recover the amounts paid and compensation for investments made. Furthermore, the revenue from betting is already included in the Annual Budget Law and the Budget Guidelines Law, which define the priorities for federal government spending.

What worries the sector is not just the threat of drastic measures against legalised betting. So far, the government has consistently fallen short in its attempts to curb the illegal market, which still represents almost half of the segment.
