Nebius is a vertically integrated cloud provider focusing on AI and high-performance computing. It is a carve-out of the previous Russian tech firm Yandex, following the Russian sanctions since the Ukraine-Russia war. Nebius designs and operates its own data centers and servers across Europe and the US, with a total capacity of several hundred megawatts. In September 2025, Microsoft became a major Nebius client under a multiyear $17 billion revenue agreement to provide computing capacity.

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.
