The 18-year-old, who took home around 12 million kronor in prize money when he won his second consecutive World Championship title on Saturday, has renewed his contract with equipment supplier Target Darts.
The PA news agency said the agreement is worth 20 million pounds over ten years, equivalent to 270 million kronor.
The agreement is the most lucrative the sport of darts has ever seen.
“Target has believed in me from day one, and I am excited to have many more years to come,” Littler said in a statement about the new contract.
Littler has been a crowd favorite since he broke through by reaching the 2024 World Cup final as a 16-year-old.
A fabulous journey then began that made Littler a super celebrity, more searched for in Britain than the king and the prime minister.
