Map the direct and indirect relationships connecting NVIDIA with OpenAI.

NVIDIA and OpenAI are directly linked through both a supply and an investment relationship: NVIDIA is OpenAI's major GPU supplier, committed to a 10-gigawatt systems deployment with up to $100 billion in related investment, and was one of three co-leads (alongside Amazon and SoftBank) in OpenAI's ~$110 billion 2026 funding round at an $840–852 billion valuation. Indirectly, they are connected through Microsoft (which invests in OpenAI and depends on NVIDIA GPUs for Azure) and through TSMC, a shared upstream manufacturing dependency for NVIDIA and competitor-turned-OpenAI-supplier AMD.

OpenAI depends on NVIDIA for GPU supply (model training/inference); NVIDIA also invested $30 billion as one of three co-leads in OpenAI's 2026 funding round alongside Amazon ($50B) and SoftBank ($30B), at an $840–852 billion valuation.

NVIDIA and OpenAI announced a September 2025 letter of intent for at least 10 gigawatts of NVIDIA systems deployment, with NVIDIA intending to invest up to $100 billion as systems deploy; a separate August 2026 arrangement has NVIDIA backing up to $105 billion in financing for an OpenAI Ohio data center.

Microsoft has invested tens of billions in OpenAI and is its largest cloud provider, while Microsoft separately depends on NVIDIA GPUs to build Azure AI infrastructure — creating an indirect NVIDIA-OpenAI link through a shared major partner.

AMD competes directly with NVIDIA, yet also supplies OpenAI (chip deal including a warrant for up to 160 million AMD shares, ~10% stake), and both NVIDIA and AMD depend on TSMC for advanced semiconductor manufacturing, making TSMC a shared upstream dependency.

NVIDIA's demand for its own hardware is reinforced twice over: directly through its OpenAI supply/investment relationship, and indirectly through Microsoft, which is both an OpenAI backer and an NVIDIA GPU customer.

OpenAI's parallel deals with AMD, AWS, Cerebras, Broadcom and Oracle suggest a deliberate diversification away from sole NVIDIA dependence, even as NVIDIA remains its largest and most financially entangled supplier.

TSMC's shared position as manufacturing dependency for both NVIDIA and AMD means any TSMC-side constraint would ripple across most of OpenAI's chip supply base, not just NVIDIA's.

NVIDIA Newsroom / CNBC (Sep 22, 2025) — 10GW systems deployment and up to $100B NVIDIA investment in OpenAI.

Tech Insider (Apr 2, 2026) — OpenAI $852B valuation funding round, NVIDIA as one of three co-leads with Amazon and SoftBank.

CNBC (Jan 16, 2026) — OpenAI-AMD chip deal with warrant for up to 160 million AMD shares.

Sacra (Feb 27, 2026) — OpenAI-AWS $50B investment and $38B compute deal.

Graph relationships: NVIDIA-OpenAI (supplies, invests-in, depends-on), Microsoft-OpenAI (invests-in, exposed-to), Microsoft-NVIDIA (depends-on/supplies), AMD-NVIDIA (competes-with), AMD-OpenAI (supplies), NVIDIA/AMD-TSMC (depends-on), OpenAI-AWS/Oracle (depends-on).

Low: Citation incomplete: “NVIDIA invests in OpenAI, having committed $30 billion as a lead investor in OpenAI's 2026 funding round” — this research pass did not retrieve directly matching evidence confirming it in full.

Medium: The dollar figures across deals ($30B investment, up to $100B tied to 10GW deployment, up to $105B in Ohio data-center financing) come from different announcements and are not fully reconciled into a single total NVIDIA commitment to OpenAI.

The relative weight of NVIDIA within OpenAI's total compute mix versus AMD, AWS Trainium, Cerebras and Broadcom is not quantified in the graph.

No direct relationship or overlap is established between NVIDIA and OpenAI's other backers (SoftBank, MGX, Amazon) beyond their shared connection to OpenAI.

The TSMC-based indirect exposure path (as a shared dependency of NVIDIA and AMD) is a structural inference from separate depends-on relationships, not a directly retrieved NVIDIA-OpenAI relationship.

Clarify and reconcile the total dollar figures NVIDIA has committed or invested in OpenAI across the $30B funding round stake, the $100B systems-deployment commitment, and the $105B Ohio financing arrangement.
