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).

Kalshi stated that these statements successfully moved market prices and that Santos realised profits totalling $17,839.57 from the trades. After detecting Santos’ trades, Kalshi froze his account then referred the matter to federal authorities, NPR reported. 

Santos criticised the exchange and its decision to ban him from trading in a series of posts on X.

But as mentioned earlier, this is not the first time Grant has been caught in a similar legal tangle with Star Casino, which accused the man of using a strategy known as “edge sorting,” which is essentially discovering an imperfection in the make of the cards used in a table game.

By leaning into that imperfection, players may then exploit the knowledge and tip the house edge in their favor. Most casinos and courts around the world consider this to be cheating.

However, the judgment in that specific case against Star Casino ruled that Grant was a self-professed advantage player, and that a casino where the staff was competent and the games were operated correctly had nothing to worry about.
