Bankole Wellington was born in the United States to Nigerian parents. The family moved back to Lagos, Nigeria when he was five; at eight he began singing in the church choir.
After completing his secondary school education, he moved to New York to attend college on a scholarship. There he earned a degree in engineering at Rensselaer Polytechnic Institute. While in college, he won the 'Albany Idol' competition, which gave him a measure of fame.
Back in Nigeria, Banky W established the Empire Mates Entertainment (E.M.E.) record label as a platform to get his music to his fans.
His first single in Nigeria was a remix of 'Umbrella' the 2007 hit by US artist Rihanna. Primarily an R&B artist, in time he became one of Nigeria's most successful pop acts, with about a half-dozen studio albums and several awards.
As record label head of EME, he signed the immensely popular Wizkid, shaping his career for the first few years. Wizkid later left the label.
After the release of his 2013 album 'R&BW', Banky W rapped on a number of songs, and he teased fans with a vague idea of a rap album. By 2016, he appeared to have gone back, releasing the solo 'Made for You' and two duets with singers Nikki Laoye and Chidinma.
