On March 31, 2026, OpenAI closed the largest private funding round in history — $122 billion in committed capital at a post-money valuation of $852 billion. Anchored by Amazon ($50B), Nvidia ($30B), and SoftBank ($30B), with continued participation from Microsoft and a sweeping syndicate of global institutions, the round dwarfs every prior private tech raise and cements OpenAI as the world's most valuable startup by a wide margin. The company is generating $2 billion in monthly revenue, counting 900 million weekly ChatGPT users, and is widely expected to pursue an IPO.
RunPod is an AI cloud infrastructure company that provides on-demand GPU compute for training, fine-tuning, and deploying AI/ML models. Founded in 2022 by two former Comcast engineers who pivoted their Ethereum mining rigs into AI servers, RunPod grew to $120M ARR with just $22M raised by early 2026, serving 500,000+ developers across 183 countries. Its marketplace model, per-second billing, and support for 30+ GPU SKUs — from consumer RTX 4090s to enterprise H100s and B200s — make it a capital-efficient disruptor to hyperscaler GPU clouds like AWS, GCP, and Azure.
