His business — Luke Littler Darts — is listed as involved in “other sports activities” and will be used for his earnings from the oche and commercial activities.
The 16-year-old’s career income was £2,500 before the World Darts Championships — but he pocketed £200,000 after his amazing run to the final, where he lost to Luke Humphries, 28.

And they estimate he will bank £40million in the course of his career.
