NVIDIA CEO Jensen Huang announced on March 4, 2026, that the company’s $30 billion investment in OpenAI—finalized just three days earlier as part of OpenAI’s historic $110 billion funding round—will be its last before OpenAI goes public. Huang also ruled out the previously touted $100 billion infrastructure deal, stating “that’s probably not in the cards” because “they’re going to go public.” The same applies to NVIDIA’s $10 billion investment in Anthropic. This marks the clearest signal yet that OpenAI’s IPO is imminent, expected in Q4 2026, and resolves the contentious “circular investment” problem where NVIDIA invested billions in companies that primarily spent that money buying NVIDIA chips.
The $100 Billion Deal That Never Materialized
In September 2025, NVIDIA and OpenAI announced a letter of intent for a $100 billion infrastructure partnership to build 10 gigawatts of AI data centers. It was touted as “the biggest AI infrastructure deployment in history.” Two months later, NVIDIA CFO Colette Kress admitted the deal remained unsigned with “no assurance” it would close. On March 4, Huang confirmed it’s dead.
The timeline exposes how AI funding announcements can be more PR than reality. September: grand announcement with press releases. December: CFO quietly admits “We still haven’t completed a definitive agreement.” March: CEO rules it out entirely due to OpenAI’s impending IPO. For developers relying on OpenAI infrastructure, this means the promised NVIDIA compute expansion won’t happen as originally planned—though OpenAI’s $110 billion round includes $100 billion in AWS compute commitments from Amazon as an alternative.
OpenAI’s IPO Is Imminent, Not Distant
Huang’s statement that NVIDIA must stop investing “because they’re going to go public” signals OpenAI’s IPO isn’t a vague future possibility—it’s soon enough that NVIDIA can’t make further pre-IPO investments. Both OpenAI and Anthropic are targeting Q4 2026 (October-December) for public offerings. OpenAI has been hiring finance executives, including a chief accounting officer and a business finance officer to oversee investor relations. Informal discussions with Wall Street banks are underway.
OpenAI closed its $110 billion funding round on March 1 at an $840 billion post-money valuation, with Amazon contributing $50 billion, NVIDIA $30 billion, and SoftBank $30 billion. Anthropic, valued between $183 billion and $300 billion, has hired law firm Wilson Sonsini and begun early-stage talks with investment banks. The market assigns a 68% probability to Anthropic’s 2026 IPO.
For the first time, retail investors will be able to buy OpenAI and Anthropic stock through standard brokerage accounts. However, at $840 billion, OpenAI is already priced higher than most public tech companies. Limited upside remains unless growth massively exceeds expectations. For developers, this means API pricing will likely increase 10-20% post-IPO as public companies optimize for shareholder profits over growth-at-all-costs strategies.

The Circular Money Problem Gets Fixed
NVIDIA’s simultaneous role as investor and chip supplier to OpenAI created a “circular investment” problem that Wall Street analysts and SEC regulators questioned. NVIDIA invests billions in OpenAI, OpenAI spends billions buying NVIDIA chips, and NVIDIA’s revenue comes from its own investments. Was this inflating revenue artificially? Bloomberg’s February 2026 investigation titled “AI Circular Deals: How Microsoft, OpenAI and Nvidia Keep Paying Each Other” raised these concerns publicly.
Economist Noah Smith argued that “the risk is that they create skewed incentives that may lead to bad decision making and magnify losses if demand for AI fails to match today’s lofty expectations.” Anthropic CEO Dario Amodei defended the practice pre-controversy, stating “I don’t think there’s anything inappropriate about that in principle.” IPOs force clean separation: NVIDIA becomes a pure chip vendor, and OpenAI becomes a standard customer with arms-length transactions.
This resolution is better for investors seeking transparent financials but potentially worse for OpenAI and Anthropic. Without equity alignment, NVIDIA may prioritize other customers. OpenAI could diversify chip suppliers to AMD or custom ASICs now that NVIDIA no longer holds board influence through equity stakes. The vendor-customer relationship replaces the strategic partnership.
What This Means for Developers and Investors
Developers using OpenAI or Anthropic APIs should expect pricing increases of 10-20% post-IPO as public companies optimize for profit margins. Quarterly earnings pressure replaces the growth-at-all-costs mentality of private startups. Lock in multi-year API contracts at current rates before Q4 2026 IPOs if possible. Build applications with multi-model support—diversify to open-source alternatives like Llama, Qwen, or DeepSeek to hedge against pricing shocks and vendor lock-in.
Investors gain retail access to AI equity for the first time, but valuations are sky-high. OpenAI’s $840 billion valuation prices in years of growth, leaving limited room for retail investors to profit unless the company dramatically exceeds expectations. Wait for the S-1 filing—expected in August or September 2026—to evaluate financials before investing. Compare valuation multiples to public competitors like Microsoft and Google’s AI divisions. Monitor insider lock-up expirations six months post-IPO; mass selling by early employees signals trouble.
NVIDIA’s relationship with OpenAI shifts from strategic partner to traditional chip vendor. The company loses board seats and strategic influence that came with equity stakes. This may reduce NVIDIA’s leverage over AI lab roadmaps and chip purchasing decisions. OpenAI and Anthropic could diversify to competing chip suppliers without equity entanglement influencing procurement.
Key Takeaways
- NVIDIA’s $30 billion OpenAI investment is its last pre-IPO funding; the $100 billion infrastructure deal announced in September 2025 was never signed and is now cancelled due to OpenAI’s impending public offering
- OpenAI’s IPO is targeting Q4 2026 (October-December), and Anthropic is likely to follow—the first time retail investors can buy AI lab equity through standard brokerage accounts
- The circular investment problem where NVIDIA invested in customers who primarily bought NVIDIA chips is resolved; IPOs force clean vendor-customer separation with arms-length transactions
- Developers should expect 10-20% API pricing increases post-IPO, lock in long-term contracts now, and diversify to open-source models like Llama, Qwen, or DeepSeek to hedge vendor lock-in risks
- Investors face $840 billion valuations for OpenAI that price in years of growth—wait for S-1 filings in August-September 2026 to evaluate financials before investing, and monitor insider lock-up expirations for early warning signs
The shift from private to public marks the AI industry’s maturation from venture-backed experimentation to quarterly-earnings accountability. For NVIDIA, the end of equity investments means cleaner financials but reduced strategic influence. For OpenAI and Anthropic, IPOs bring capital market access but shareholder pressure to prioritize profits over pure research. For developers and investors, transparency improves but costs likely rise. The circular money is untangled, and the bills come due.
