The AI industry’s two most valuable private companies are facing intense investor scrutiny around their public-market plans and the extraordinary capital required to build and operate frontier artificial intelligence systems.
Anthropic’s IPO has reportedly shifted from an expected October timetable toward November 2026, according to The Wall Street Journal. The reported reason includes allowing the company to present stronger third-quarter financial results to prospective investors.
Separately, OpenAI is reported to expect approximately $278 billion in negative free cash flow between 2026 and 2030, according to the Financial Times, citing a company presentation. The projection highlights the enormous cost of training and operating frontier AI systems.
Important distinctions: Anthropic’s IPO timing is a reported plan, not a completed public filing or listing. OpenAI’s $278 billion figure is a company projection, not money already lost.
Anthropic IPO: What Happened?
According to reporting from The Wall Street Journal, Anthropic had been expected to stage a record-breaking IPO in October 2026. The company now plans to pursue its offering in November, later than many investors anticipated.
The shift was reportedly decided before Anthropic CEO Dario Amodei published a blog post calling for a slowdown in frontier AI development. Sources familiar with the timing told the WSJ that the decision to target November was made independently of the public debate that followed.
Some of Anthropic’s advisers indicated that waiting until November would give the company time to share third-quarter financials demonstrating a strong competitive position, even after rival OpenAI launched its newest model, Astra, in September.
Anthropic has not officially confirmed a delay. The information comes from people familiar with the matter, and the timing could still change.
Why Would Anthropic Delay an IPO?
The reported rationale centers on timing and financial presentation.
Reported reason: Anthropic advisers say waiting until November allows the company to present third-quarter financial results to prospective investors. This would demonstrate competitive strength following OpenAI’s September release of its GPT-6 Astra model.
Possible market considerations: Analysts and investors have noted broader factors that could influence IPO timing, including market conditions, investor appetite for AI stocks, and the company’s valuation expectations. Anthropic’s existing investors expect the company to reach more than $110 billion in annualized revenue by year-end, up from $65 billion in July.
The reported delay does not indicate Anthropic is abandoning its IPO plans. The company is proceeding with investor meetings to gauge appetite for the offering.
How Big Could the Anthropic IPO Be?
Current reporting suggests Anthropic could target a valuation around $2 trillion** and raise up to **$100 billion in its IPO. If achieved, these figures would surpass records set by SpaceX’s June 2026 debut.
Important context: Valuation is not the same as market capitalization after listing. Final IPO pricing depends on investor demand, market conditions, and the company’s financial performance at the time of the offering. No final share price should be considered confirmed unless officially filed.
Anthropic raised $65 billion in a May 2026 funding round at a $965 billion post-money valuation. The company’s annualized revenue run rate grew from $47 billion in mid-May to $65 billion by end of July.
OpenAI’s $278 Billion Cash-Burn Projection
According to the Financial Times, OpenAI expects approximately $278 billion in negative free cash flow between 2026 and 2030. The figure appeared in a private company presentation related to a computing deal.
What this means: Negative free cash flow indicates that a company is spending more cash than it generates from operations over a given period. It does not mean the company will lose $278 billion in accounting terms or that the money has already been spent.
Key financial terms explained:
- Revenue: Money generated from selling products or services
- Operating costs: Day-to-day expenses like salaries, research, and infrastructure
- Capital expenditures: Investments in long-term assets like data centers and equipment
- Free cash flow: Operating cash flow minus capital expenditures
- Negative free cash flow: When capital expenditures exceed operating cash flow, requiring external funding
OpenAI’s projection reflects the massive infrastructure investments required to train and run frontier AI models.
Where Is OpenAI Spending the Money?
Reuters reported that OpenAI expects roughly $856 billion in computing and infrastructure spending through the end of 2030. This is the company’s largest expense category.
The spending encompasses:
- AI data centers
- GPUs and AI accelerators
- Electricity and power infrastructure
- Networking equipment
- Model training costs
- Model inference (running AI for users)
- Cooling systems
- Cloud infrastructure contracts
Important distinction: This is projected spending, not money already committed or spent. The actual figures will depend on execution, efficiency improvements, and changes in technology or strategy.
OpenAI Revenue Is Also Expected to Grow Rapidly
The cash-burn discussion must be balanced with OpenAI’s revenue projections.
According to the Financial Times, OpenAI expects revenue to grow from approximately $36 billion in 2026 to $350 billion in 2030 — a nearly tenfold increase. Cumulative revenue from 2026 through 2030 is projected at approximately $840 billion.
This demonstrates that high projected revenue growth and high projected cash spending can happen simultaneously. The key distinction is between revenue growth and free-cash-flow generation. A company can generate billions in revenue while still requiring external capital if its investment needs exceed its operating cash flow.
OpenAI’s Funding Needs
Despite generating substantial revenue, OpenAI requires significant additional capital.
According to Reuters, OpenAI raised $122 billion in March 2026** at an **$852 billion valuation. The company’s own presentation indicated that this cash could be exhausted by 2028 — two years before the burn forecast ends.
The Financial Times reported that OpenAI is in early discussions for new financing that could value the company at over $1.2 trillion, approximately 41% above the March valuation.
OpenAI CEO Sam Altman has stated that OpenAI will not go public in 2026, citing safety considerations and saying it would be an “ill-advised moment” for an IPO.
Why AI Companies Need So Much Computing Power
The capital requirements reflect fundamental characteristics of frontier AI development.
Training: Building large language models requires enormous computing resources. Training runs can consume thousands of specialized chips over weeks or months.
Inference: Every time a user interacts with a model, computing resources are consumed. As user bases grow into the hundreds of millions, inference costs scale dramatically.
Enterprise AI: Businesses increasingly use AI for coding, customer service, research, data analysis, cybersecurity, and professional workflows. These applications require reliable, low-latency infrastructure.
Scale: More users and more sophisticated models increase infrastructure requirements in ways that can outpace revenue growth in early stages.
Anthropic and OpenAI have both secured massive computing capacity deals. Anthropic announced agreements with Amazon for 5 gigawatts of computing power and with Google and Broadcom for another 5 gigawatts of TPU capacity.

Both companies are private, and their financial information is less comprehensive than that of established public companies. Reported figures are projections and may change.
OpenAI IPO vs Anthropic IPO
The two companies have taken contrasting approaches to public markets.
Anthropic is reportedly preparing for a potential November 2026 IPO. OpenAI CEO Sam Altman stated in September 2026 that OpenAI will not go public in 2026, citing safety work and saying “we don’t feel pressure on that.”
These are different corporate decisions based on different circumstances. Anthropic’s reported delay does not mean it is abandoning its IPO. OpenAI’s decision does not confirm it will definitely IPO in 2027, though Altman’s comments suggest 2027 is the earliest possibility.
What Does This Mean for AI Investors?
When AI companies eventually go public, investors may examine several factors:
- Revenue growth and trajectory
- Gross margins
- Free cash flow generation
- Capital expenditure requirements
- Infrastructure commitments
- Customer concentration
- Enterprise adoption rates
- Model-development costs
- Competitive positioning
- Dependence on chip suppliers
- Energy costs
- Regulatory risks
What Could Determine Anthropic’s IPO Valuation?
Several factors could influence Anthropic’s eventual public-market valuation:
- Annualized revenue and growth rate
- Enterprise customer base and retention
- Margins and unit economics
- Infrastructure costs
- Cash position and funding needs
- Competitive position vs. OpenAI and others
- Model performance and capabilities
- Overall market conditions
- Investor demand for AI exposure
A private valuation is not necessarily the same as the eventual public-market valuation. Final pricing depends on conditions at the time of the offering.
Why Third-Quarter Results Matter
The reported IPO delay would allow Anthropic to present more recent financial data to investors.
Third-quarter results could show:
- Revenue growth trajectory
- Enterprise adoption metrics
- Margin trends

Anthropic’s investors expect the company to reach more than $110 billion in annualized revenue by year-end, up from $65 billion in July. Specific third-quarter figures have not been publicly confirmed.
Anthropic’s Competition With OpenAI
The AI competition extends across multiple dimensions.
Reuters reported that OpenAI’s GPT-6 Astra, launched in September 2026, gained enterprise traction. Anthropic is reportedly considering a new model release ahead of its IPO to maintain competitive positioning.
The competition encompasses:
- Model capabilities and benchmarks
- Enterprise adoption
- Developer ecosystems
- Coding and professional workflows
- AI agents and automation
- Pricing and packaging
Neither company’s model should be declared superior without specific, transparent benchmark evidence. Capabilities can shift rapidly with each new release.
