Alphabet is a holding company that wholly owns internet giant Google. The California-based company derives slightly less than 90% of its revenue from Google services, the vast majority of which is advertising sales. Alongside online ads, Google services houses sales stemming from Google's subscription services (YouTube TV and YouTube Music, among others), platforms (sales and in-app purchases on Play Store), and devices (Chromebooks, Pixel smartphones, and smart home products such as Chromecast). Google's cloud computing platform accounts for roughly 10% of Alphabet's revenue. The firm's investments in up-and-coming technologies such as self-driving cars (Waymo), health (Verily), and internet access (Google Fiber) make up the rest.

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.
