Banton thumped a 47-ball hundred en route to an unbeaten 107 from 51 balls as Somerset cruised past Kents 168-8 with 26 balls to spare.
The 22-year-old blazed seven sixes and eight fours in a chanceless knock as he bossed an unbroken opening partnership of 169 with New Zealander Devon Conway (51no off 44), who hit the winning run in the 16th over.
Asked afterwards if he was now eyeing a place in Englands T20 World Cup squad later this year, Banton said: "I think it would be silly not to [be thinking about that] but at the moment I am trying to score as many runs as possible.
"The year has not gone as well as I would have liked so hopefully this is a changing point for me. I am not going to look too far ahead."
Lewis Gregory claimed 4-27 and Craig Overton 2-40 for Somerset as Kent slipped from 125-2 amid thick mist after being inserted by Somerset - Zak Crawley scored 39 from 32 balls, while Joe Denly struck 36 from 25.
As the mist cleared, Somerset cantered through the powerplay to 73-0 with Banton sealing a 22-ball fifty by hitting Fred Klaassen for six over fine leg.
Bantons extraordinary striking included two sixes off Darren Stevens in the ninth over and two off Denly in the 11th as the Somerset man followed his 77 from 37 balls against Hampshire last time out.
