Meta Platforms owns Facebook (3B+ monthly users), Instagram (2B+), WhatsApp (2B+), and Messenger - the four most-used social apps globally. Its advertising platform reaches 4B people. Its Reality Labs division is building the metaverse through Quest VR headsets and Ray-Ban smart glasses. Metas AI investments made its Llama models the most popular open-source AI.
Key relationships in depth
Apple and Meta are direct competitors in augmented and virtual reality, with Apple Vision Pro (launched 2024) competing with Meta Quest 3 and Meta's Ray-Ban smart glasses for spatial computing mindshare. Meta's social platforms (Facebook, Instagram, WhatsApp) are among the highest-grossing apps on the App Store, making Meta one of Apple's largest revenue contributors through the 30% App Store commission, while Meta simultaneously lobbies aggressively against Apple's App Store policies in regulatory proceedings globally.
Why it matters: Meta's advertising business is existentially dependent on iPhone data that Apple's App Transparency Framework (ATT) restricted in 2021, and Meta has built its AI-powered advertising recovery strategy specifically to reduce its dependence on Apple device-level data. Apple's privacy stance directly reduces Meta's ability to target iOS users, creating a fundamental business conflict even as Meta pays billions in App Store fees.
Meta and Microsoft have a multi-layered relationship spanning AI model distribution, enterprise software integration, and competitive tension in productivity AI. Meta's Llama open-source models are distributed through Azure AI Studio and the Azure Marketplace, giving Microsoft a competitive open-source option against OpenAI's proprietary GPT models. Microsoft also integrates Meta's AI tools into enterprise workflows, while the two companies compete indirectly through Meta AI vs Microsoft Copilot in consumer and enterprise AI assistants.
Why it matters: Microsoft distributes Llama through Azure to offer customers a lower-cost, customizable alternative to GPT-4 subscriptions, broadening Azure's AI appeal without cannibalizing OpenAI revenue significantly since the use cases often differ. Meta benefits from Azure's enterprise distribution reach, pushing Llama adoption into Fortune 500 companies that Meta could not otherwise access through its own channels.
Meta deployed more than 350,000 NVIDIA H100 GPUs by mid-2024, making it one of the largest single NVIDIA customers in history. These GPUs train Meta's Llama large language models, power the AI recommendation systems driving Facebook and Instagram engagement, and support Meta's AI assistant across all its platforms.
Why it matters: Meta's ad revenue model, which generated $164B in 2024, depends on AI-powered content ranking and ad targeting. The more powerful the AI, the better the recommendations, the higher the engagement, and the more advertisers pay. Meta's 40% increase in ad prices in 2024 was directly attributable to AI improvements funded by NVIDIA GPU investment.
Meta and Google collectively command approximately 48-52% of global digital advertising spend, making them the two dominant players in the $750B+ digital ad market. Their ad platforms compete directly for brand and performance advertiser budgets. At the same time, the two companies entered a 6-year, $10B+ cloud computing partnership where Meta uses Google Cloud for specific AI workloads.
Why it matters: The advertising relationship between Meta and Google defines modern internet economics. Every dollar a brand shifts from TV to digital flows primarily to one or both of these companies. Despite their competitive relationship in ads, the cloud partnership reflects how the two largest tech companies can simultaneously compete and collaborate.
