About Piggy Heist
“Looking back over the past two years, the regulation has achieved its primary objective: creating a safer and more transparent market. It has established common standards for all licensed operators, particularly around KYC, AML and responsible gaming, ensuring that customers receive a more consistent experience regardless of the platform they choose.”
Atucha praises the regulation and the regulators themselves for making entry into the market easy, as well as allowing them to be competitive against illegal operators. But the market hasn’t been without its challenges.
A 1% selective consumption tax (ISC) on the value of every online bet has been in force since 1 July 2025, after the original policy was scrapped from proposed regulations in July 2021.
What is Piggy Heist?
This followed a period of restrategising for the operator, after rebranding from GVC Holdings and committing to having 100% of its revenues come from regulated markets.
But its share price has taken a tumble over the last year, dropping up to 37% since September 2025. Its market cap currently sits at £3.39 billion.
The operator first started trading on LSEG’s main market in February 2016 under its previous company name GVC Holdings. This followed its delisting from the Alternative Investment Market (AIM exchange).
