Who supplies AI chips?

I'm curious to know, who exactly are the primary suppliers of AI chips? Are they large multinational corporations, or are there specialized companies that focus solely on this niche market? Furthermore, what factors influence the choice of suppliers for AI chip technology? Is it solely based on price, or are there other considerations such as quality, reliability, and innovation that play a role in the decision-making process? Additionally, are there any emerging players in the market that are worth keeping an eye on, as they might be able to offer unique advantages over the established suppliers?
