Nvidia, founded in 1993 by Jensen Huang, Chris Malachowsky, and Curtis Priem, invented the modern GPU (GeForce 256, 1999) and then - via the 2006 CUDA platform - turned it into the engine of the AI revolution. It touched a record $5.06 trillion valuation in late July 2026 and then briefly slipped to about $4.77 trillion on July 27, 2026 as Apple reclaimed the world's-most-valuable-company title amid a broader AI-financing selloff, but Nvidia rallied back through early August - its biggest one-week market-cap gain ever - to reclaim the crown at about $5.42 trillion (Aug 7, 2026 close), before easing back to roughly $5.29 trillion (Aug 28, 2026 close, $217.89/share) after Q2 FY2027 gross-margin guidance drew a mixed reaction. Fiscal 2026 revenue hit $215.9B (+65%), and the momentum accelerated: Q2 FY2027 (ended July 2026, reported August 26, 2026) delivered a record $96.2B (+106% YoY, beating the $92.2B consensus) with data-center revenue of $89.0B (+117% YoY), CFO Colette Kress guiding Q3 to ~$108B and roughly 70% revenue growth for FY2028, and supply commitments more than doubling to $279B (mostly HBM memory) against a hyperscaler cloud backlog exceeding $2 trillion. The Blackwell Ultra GB300 platform drove the ramp, and Vera Rubin - the seven-chip platform Huang declared in full production at GTC 2026 - reached customers on July 21, 2026, shipping to OpenAI, CoreWeave, Google Cloud, Microsoft Azure, Meta, and Dell, with OpenAI set to deploy it at scale in Q3 2026 and roughly $1 trillion in cumulative Blackwell-plus-Rubin orders projected through 2027. Nvidia has also become the AI buildout's central dealmaker: up to $100B invested in OpenAI (whose Ohio campus financing was finalized at $105B for an initial 4.25 IT-GW, online in phases from 2028), up to $10B in Anthropic, a key role in the $500B Stargate project, millions of GPUs committed to Meta, an August 10-11, 2026 financing coalition with Apollo, Blackstone, BlackRock, Brookfield, Goldman Sachs, and KKR aiming to mobilize over $500B in third-party AI-compute capital, and - confirmed September 3, 2026 - a $12.93B deal to acquire AI model-hosting platform Hugging Face, Nvidia's largest acquisition ever, alongside talks to invest in Perplexity at a valuation above $30B, plus a confirmed August 31, 2026 $3.5 billion convertible-bond investment in MediaTek that opens NVLink Fusion to MediaTek custom XPUs in Nvidia rack-scale AI factories. That expanding web of AI financing, alongside a recurring circular-financing debate, remains the biggest swing factor in Nvidia's valuation. The China business is the big casualty - export restrictions triggered a $4.5B charge in 2025, and while H200 shipments to China stayed 'trivial' through mid-July 2026 under the deal with a 25% cut to the US government, ByteDance and Tencent each received roughly 10,000 H200 units in the weeks before August 19, 2026, still only about 13% of the 75,000-unit licenses each holds; Nvidia's 10-K still calls the company effectively foreclosed from China's data-center market and its guidance assumes zero China data-center revenue. Competition now comes less from AMD (still ~5-7% of AI accelerator revenue) than from customers' own silicon: Google TPUs, AWS Trainium, Broadcom-built custom ASICs, and OpenAI's own Jalapeno inference chip unveiled August 25, 2026.
