Which of the Big Four accounting firms continues to sponsor Visa?

As of the latest available data, it is important to note that sponsorship agreements between companies and athletes, teams, or events can change frequently. The Big Four Accounting firms—Deloitte, PwC (PricewaterhouseCoopers), EY (Ernst & Young), and KPMG—may engage in various sponsorships or partnerships, but specific information on which of these firms is sponsoring Visa (assuming this means a direct business partnership or event-related sponsorship related to Visa, the financial services corporation) would typically not be widely publicized in standard reports. If you are referring to sponsorship in terms of events like the Olympics or other global sports activities that Visa sponsors, it’s more common to find Visa as a sponsor of events rather than being sponsored by other companies. Therefore, if you are specifically looking for which of these firms sponsors Visa, it’s unlikely any of the Big Four directly serves as a sponsor, but they may have partnerships related to financial services and consulting. For current and specific sponsorship information, I recommend checking recent press releases or the official announcements of the companies involved.
