Apple is among the largest companies in the world, with a broad portfolio of hardware and software products targeted at consumers and businesses. Apple's iPhone makes up a majority of the firm sales, and Apple's other products like Mac, iPad, and Watch are designed around the iPhone as the focal point of an expansive software ecosystem. Apple has progressively worked to add new applications, like streaming video, subscription bundles, and augmented reality. The firm designs its own software and semiconductors while working with subcontractors like Foxconn and TSMC to build its products and chips. Slightly less than half of Apple's sales come directly through its flagship stores, with a majority of sales coming indirectly through partnerships and distribution.

Since its founding in 1962, Walmart has become the world's largest retailer, operating over 10,700 stores globally (including 4,600 namesake locations on its home turf and another 600 Sam's Club outlets) and growing its e-commerce presence, attracting 270 million customers weekly. In aggregate, the firm posted more than $680 billion in fiscal 2025 sales. Its core operations span three reporting segments: Walmart US (68% of fiscal 2025 sales), Walmart International (18%), and Sam's Club (14%). Within the US, nearly 60% of its $465 billion in fiscal 2025 revenue came from its grocery offerings, with another quarter from general merchandise. Internationally, Walmart's operations are concentrated in Mexico, though it also has budding exposure to India.
