How to play Dolphin Reef
The dual approach seeks not only to limit access to gambling content on smartphones but also to provide meaningful alternatives that reduce overall reliance on digital devices.
The KGCC, which operates under the prime minister’s office and oversees gambling supervision and the monitoring of illegal gambling activity, will collaborate with the Gyeonggi education office. There will be policy coordination, student protection and the exchange of educational resources and prevention experts.
The partnership also plans to analyse operational data, develop pilot programmes and construct a model for national deployment.
About Dolphin Reef
“The new hub will display probability data from Polymarket for key economic, government, & market outcomes,” said Polymarket in a post on X last November. “Each probability view will be paired with related news, quotes, & analysis from Yahoo Finance + its partners. By combining trusted data with in-depth analysis, the hub will empower investors to make smarter, more strategic prediction market investments.”
Yahoo—which is 90% owned by private equity giant Apollo Global Management, the firm that acquired operating control of The Venetian in Las Vegas—did not elaborate on why the Polymarket integration ended.
Yahoo Finance is one of the most visited financial news websites in the world, implying it’s a blow to Polymarket that its prediction market hub was pulled, but the operator has other prominent financial media deals.
What is Dolphin Reef?
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.
