About Mega Shark

It had sent over 217,000 marketing emails and SMS messages within a 16-day window to customers who had explicitly unsubscribed. ACMA regarded the volume and timing of these messages as significant enough to warrant enforcement action. 

In response to the penalties, Dabble Sports has agreed to a two-year court-enforceable undertaking. It has obliged the company to commission an independent review of its compliance systems. Dabble must develop a board-approved plan to implement these changes with appropriate resources.

An ACMA spokesperson reiterated: “BetStop is an important consumer protection measure, but it only works if wagering companies follow the rules.” 

What is Mega Shark?

Commercial sports betting generated just under $17 billion in nationwide revenue in 2025, which is why Davenport asserts that the “stakes of this case are exceptionally high”. Kalshi and Polymarket alone posted more than $45 billion in trading volume, which is similar but not identical to betting revenue, in August. That was a 15% decline from July, although that drop is attributed to the conclusion of the Fifa World Cup tournament that month per Yahoo! Finance.

The American Gaming Association estimates that the exchanges have siphoned more than $1.3 billion in would-be tax revenue from states. One of the AGA’s primary spokespeople pin its fight against prediction markets is former New Jersey governor Chris Christie, who championed the PASPA case to the Supreme Court.

As with PASPA, this matter revolves heavily around federalism versus states’ rights. Traditional sports betting is governed by individual state regulators with varying laws and regulations. Federal derivatives are regulated by the CFTC, which has fully embraced prediction markets under US President Donald Trump after rejecting them in previous administrations.

With such a significant rise in tax, you would forgive the company for cutting wherever possible, but Petra says they have made it work by maximising efficiency, restructuring, and maintaining their offering so the customer doesn’t notice that anything has changed.

“We feel that people are always interested in gambling and that we are the party who should offer that in a safe way. [Holland Casino] has been careful to maintain that, but of course our costs rose very quickly, so we restructured at our head office. We have also been looking at innovations in offerings, which we are currently also testing, including a further development of the Next Zone. We’ve also introduced the double zero in roulette, which we didn’t have previously in the Netherlands,” the CEO says.

“Obviously, in the gaming industry we don’t have a price tag on our product where you can just change the RTP (return-to-player) and your problem is solved, it doesn’t work like that. Especially not if you take responsible gaming seriously.”
