He's also one of the most polarising, making headlines on a near-constant basis for his penchant to say things many view as controversial. On Thursday, he met with US President Donald Trump, one of the most polarising figures in the world, and apparently ad-libbed a 10-minute monologue.
But West's sometimes erratic behaviour doesn't worry Adidas' leadership.
"When you have a business model like ours, of course there are liabilities, but also opportunities that go hand in hand," Adidas' global CEO, Kasper Rorsted, told Business Insider during an interview earlier this week.
He went on to say that if a big asset for the brand, like a collaborator or sports star, misbehaves, "eventually it could have a negative impact on the perception of the brand."
Rorsted emphasised that Adidas does its due diligence when choosing its collaborators.
"Of course, we look upon what do they bring to the table and do they represent certain views that are not aligned with our values," he said.
But, Rorsted said he doesn't worry too much about them saying something controversial.
"When you engage with people of very high creativity, they are different in the way they act. How they behave. That's part of the equation, what they bring to the entire table. That they are so different," Rorsted said. "If you want the mainstream, you get the mainstream all the way."
"If you want the ultimate creativity, then you get that, and you have to live with the fact that sometimes some person will say something that maybe you don't subscribe to, but there might be others that do subscribe to it," Rorsted continued.
"We operate in 75 countries. If you start putting the glasses of appropriateness on, is it your appropriateness? Is it mine? Is it the one in China? Who is actually measuring the level of appropriateness that the company is being judged upon?"
Rorsted said that Adidas has "hardly any political view," but it does have a stance on issues like sustainability, fair trade, and labour.
"Frankly, we can't have a view on politics," Rorsted said. "There's 75 countries [that Adidas does business in], by default you have 75 different governmental systems."
