The Central Question
Section titled “The Central Question”Investors have poured unprecedented capital into AI. Hyperscalers alone plan to spend ≈$700 billion on AI infrastructure in 2026—Amazon ($200B), Microsoft (≈$145B), Google (≈$93B), Meta ($115-135B). CNBC Yahoo Finance Private AI companies raised a record $225.8 billion in 2025, nearly double 2024, capturing ~50% of all global startup funding. Crunchbase
The question is simple: where does the revenue come from to justify this?
Sequoia’s David Cahn framed this as “AI’s $600B Question”: take Nvidia’s revenue, multiply by 2x for total data center cost, multiply by 2x again for end-user margins, and you get the revenue AI companies need to generate. The result was a $500B+ gap between required revenue and actual AI revenue being generated—roughly a 6x shortfall.
Current AI Revenue by Category
Section titled “Current AI Revenue by Category”1. Hardware and Chips (≈$130B+)
Section titled “1. Hardware and Chips (≈$130B+)”The largest AI revenue stream is not software—it’s silicon. Nvidia captured $130.5 billion in FY2025 revenue (114% YoY growth), with data center GPUs accounting for 89% of revenue. Statista Nvidia commands 80-92% of the data center GPU market. Carbon Credits AMD’s AI chip revenue is projected at $5.6B in 2025, growing toward “tens of billions” by 2027. Deloitte predicts generative AI chips will approach $500 billion in revenue in 2026, roughly half of global chip sales. Deloitte
Why this matters for safety: Hardware revenue is the most concrete layer—actual products shipped for actual dollars. But it’s upstream: Nvidia revenue reflects spending, not downstream value creation. If the downstream value doesn’t materialize, chip demand eventually contracts.
2. AI-Enhanced Advertising (≈$60B+)
Section titled “2. AI-Enhanced Advertising (≈$60B+)”The least-discussed but possibly most important AI revenue source. MetaOrganizationMeta AI (FAIR)Meta AI has invested $66-72B in AI infrastructure (2025) with AGI targeted for 2027, pioneering open-source AI through PyTorch (63% market share) and LLaMA (1B+ downloads). However, the organizatio...Quality: 47/100’s AI-powered Advantage+ ad suite has a run rate exceeding $60 billion, delivering measurable 3.5% YoY lift in ad clicks on Facebook and 1%+ gain in conversions on Instagram. Marketing Brew Futurum Meta’s total 2025 ad revenue hit $196.2B (total revenue $201B), projecting ≈$251B in 2026.
Google Search revenue: $161.4B through the first three quarters of 2025 (12% growth), with AI increasingly powering ad targeting and placement. The Keyword
Key insight: Advertising AI is already profitable because it enhances existing multi-hundred-billion-dollar businesses rather than creating new ones. Meta and Google don’t need to convince enterprises to buy a new product—they just need AI to make existing ads slightly more effective. This is the clearest example of AI generating measurable ROI at scale.
3. Cloud Provider AI Services (≈$25B+)
Section titled “3. Cloud Provider AI Services (≈$25B+)”AI is the primary growth driver for the three major cloud platforms:
| Provider | Total Cloud Revenue (2025) | AI Contribution | Growth Signal |
|---|---|---|---|
| AWS | $126.6B (18% growth) | Bedrock adoption 4.7x YoY | $195B backlog |
| Azure | ≈$87.7B IaaS/PaaS (31% growth) | AI added ≈$25B in FY2026 | $368B RPO (+37%) |
| Google Cloud | ≈$45B+ (32% growth) | ≈$0.6B direct AI services (Q2 2025) | $155B backlog (+82%) |
Sources: CNBC, Futurum, SiliconANGLE
Combined cloud backlog: $718 billion, representing years of committed spending. Andy Jassy has said Bedrock could be “as big as EC2”—if true, that alone would be a multi-tens-of-billions business.
Complication: It’s difficult to separate “AI revenue” from “cloud revenue.” When an enterprise buys Azure to run AI workloads, Microsoft counts it as Azure revenue. The $25B Azure AI figure likely includes workloads that would have been cloud spend regardless.
4. Consumer Subscriptions (≈$10B)
Section titled “4. Consumer Subscriptions (≈$10B)”| Product | Users | Paying Subscribers | Revenue |
|---|---|---|---|
| ChatGPT | 700-800M weekly active | ≈20M paying | ≈$5.5B in 2024 (≈75% of OpenAI revenue) |
| ChatGPT Plus ($20/mo) | — | Majority of paid base | — |
| ChatGPT Pro ($200/mo) | — | Small fraction | — |
| Claude Pro ($20/mo) | — | Undisclosed | Small share of Anthropic revenue |
Sources: Business of Apps, SaaStr
Consumer subscriptions were OpenAI’s primary revenue source through 2024 (~85% of ARR), but API revenue has now surpassed it. ChatGPT Plus has strong retention: 89% after one quarter, ~74% beyond nine months. Sacra AnthropicLabAnthropicComprehensive profile of Anthropic, founded in 2021 by seven former OpenAI researchers (Dario and Daniela Amodei, Chris Olah, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish) with early funding...Quality: 51/100 earns ~80% from enterprise/developer workloads, making consumer subscriptions a smaller share.
5. API and Inference Revenue (≈$15B+)

AnthropicLabAnthropicComprehensive profile of Anthropic, founded in 2021 by seven former OpenAI researchers (Dario and Daniela Amodei, Chris Olah, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish) with early funding...Quality: 51/100’s API revenue is expected to hit $3.8 billion in 2025—reportedly doubling OpenAI’s $1.8B in API revenue for the same period. Tom’s Hardware Major API customers include Cursor and GitHub Copilot.
Structural challenge: API prices are falling exponentially due to competition and efficiency gains. Revenue growth depends on volume outpacing price declines—which has held so far, but can’t be assumed indefinitely.
6. Coding Tools (≈$4B)
Section titled “6. Coding Tools (≈$4B)”Coding is the single largest application-layer AI category at $4.0 billion in enterprise spending (55% of departmental AI spend). Menlo Ventures
| Product | Revenue/ARR | Users | Market Share |
|---|---|---|---|
| GitHub Copilot | ”Larger than all of GitHub at $7.5B acquisition” | 20M+ users, 1.3M paid | ≈42% |
| Cursor (Anysphere) | $500M+ ARR | Growing rapidly | ≈18% |
| Claude Code | ≈$1B ARR | — | Growing |
Sources: Business of Apps, Opsera, Uncover Alpha
AI coding market overall: $7.37B in 2025, projected to reach $30.1B by 2032 (27.1% CAGR). Gartner forecasts 90% of enterprise software engineers will use AI coding assistants by 2028, up from <14% in early 2024.
Why coding matters: It’s the most proven AI use case with measurable productivity gains. It also has clear willingness-to-pay—developers and their employers can directly observe time saved.
7. Enterprise SaaS and Productivity
Section titled “7. Enterprise SaaS and Productivity”Microsoft 365 Copilot: 4.7 million paid subscribers (up 75% YoY), used by 90% of Fortune 500. Pricing reduced from $30/user/month to $18-21 for smaller orgs. Business of Apps Over 80% of Fortune 500 have active agents built using Microsoft’s Copilot Studio. PYMNTS
Enterprise generative AI spending: $37 billion in 2025, up 3.2x from $11.5B in 2024. Menlo Ventures
8. AI Agents and Automation (≈$8B)
Section titled “8. AI Agents and Automation (≈$8B)”Global AI agents market: $7.6-7.8 billion in 2025, projected to reach $10.9B in 2026, growing at ~46% CAGR to $52.6B by 2030. Grand View Research Gartner forecasts 40% of enterprise applications will embed task-specific AI agents by 2026, up from <5% in 2025.
This is the most speculative category—high projected growth rates but from a small base, and most agent products are still in early deployment.
Revenue Summary
Section titled “Revenue Summary”Total across categories: Roughly $250-300 billion, but this double-counts significantly. Hardware revenue is spent by the same companies generating cloud and API revenue. Advertising AI revenue is incremental improvement on existing businesses, not new revenue. The truly new AI revenue—from products and services that wouldn’t exist without AI—is closer to $50-80 billion.
The Capex-Revenue Gap
Section titled “The Capex-Revenue Gap”How the Numbers Stack Up
Section titled “How the Numbers Stack Up”| Metric | 2025 | 2026 (Projected) |
|---|---|---|
| Hyperscaler AI capex | ≈$360-400B | ≈$700B |
| AI depreciation costs | ≈$22B/quarter | ≈$30B/quarter |
| New AI revenue (products that wouldn’t exist without AI) | ≈$50-80B | ≈$100-150B |
| AI-enhanced revenue (existing products improved by AI) | ≈$60-100B | ≈$100-150B |
| Capex consumed as % of operating cash flows | 76% (2024) → 94% (2025) | Likely >100% |

Free Cash Flow Impact
Section titled “Free Cash Flow Impact”The spending is already crushing free cash flow:
| Company | 2025 FCF | 2026 FCF (Projected) | Change |
|---|---|---|---|
| Alphabet | $73.3B | ≈$8.2B | -89% |
| Meta | ≈$50B+ | Down ≈90% | ~-90% |
| Amazon | Positive | -$17 to -$28B | Negative |
| Microsoft | ≈$60B | Down ≈28% | -28% |
Source: CNBC
The combined free cash flow of the four biggest U.S. internet companies fell from $237B (2024) to $200B (2025) and is projected to drop much further in 2026.
Circular Financing Concerns
Section titled “Circular Financing Concerns”Nobel laureate Daron Acemoglu and others have flagged a circularity problem: Nvidia invests in OpenAI, which buys Nvidia chips. Microsoft owns 27% of OpenAI and represents ~1/5 of Nvidia’s revenue. OpenAI partners with CoreWeave, in which Nvidia also has a stake. NPR Yale Insights At some point, someone outside the loop needs to pay real money for AI products—the question is whether downstream customers are emerging fast enough.
Company Revenue Projections
Section titled “Company Revenue Projections”| Company | 2025 | 2026 Target | Longer-term | Valuation |

OpenAI expects annual losses through 2028, including $74B in operating losses in 2028. Anthropic targets breakeven by 2028 with improving gross margins (from negative 94% to 50% in 2025, targeting 77% by 2028).
Bear Case: Why Revenue May Disappoint
Section titled “Bear Case: Why Revenue May Disappoint”1. Enterprise ROI is unproven at scale. MIT Media Lab reported that “despite $30-40 billion in enterprise investment, 95% of organizations are getting zero return” from generative AI. If this doesn’t change, enterprise spending growth will stall.
2. The capex-revenue ratio is historically dangerous. AI capex at $700B against $50-80B in new AI revenue is a 9-14x mismatch. The dot-com era’s fiber optic overbuild eventually led to utilization rates below 5%. FX Empire
3. Market concentration is extreme. 30% of the S&P 500 and 20% of MSCI World is held by just 5 companies—the greatest concentration in half a century. The Case-Shiller P/E ratio exceeded 40 for the first time since the dot-com crash. Wikipedia
4. Depreciation is eating earnings. Combined depreciation for Alphabet, Microsoft, and Meta is rising from ≈$10B/quarter (Q4 2023) to ≈$30B/quarter (late 2026). This directly reduces reported profits even if revenue grows.
5. Private credit exposure. ≈$200 billion in data-center debt was raised in 2025 alone, with GPU-backed collateral and complex leasing structures involving borrowers untested in a downturn—drawing parallels to 2008 structured finance. Yale Insights
6. API price deflation. Inference costs are falling rapidly. Volume has to grow faster than prices fall for revenue to increase. At some point, AI inference may commoditize like cloud compute did.
Bull Case: Why Revenue Will Materialize
Section titled “Bull Case: Why Revenue Will Materialize”1. Revenue growth is real and unprecedented. OpenAI went from $200M to $13B in two years. Anthropic went from $87M to $9B ARR in 18 months. These are among the fastest revenue trajectories in technology history—faster than Google, Facebook, or AWS at comparable stages. Visual Capitalist
2. Unlike the dot-com bust, these companies have real revenue. Fed Chair Jerome Powell noted that AI firms are generating actual revenue and measurable economic output. Corporate cash flow is 3x its 1999 level. Brookings
3. Advertising AI is already profitable at massive scale. Meta’s $60B+ Advantage+ run rate shows AI can improve existing businesses without requiring new product adoption. This alone could justify tens of billions in infrastructure spending.
4. Cloud backlogs provide visibility. Combined backlog of $718B (AWS $195B + Azure $368B + Google Cloud $155B) represents years of committed spend. These are signed contracts, not projections. CNBC
5. Coding is a proven and growing use case. At $4B and 55% of app-layer spend, coding is clearly generating ROI. With Gartner projecting 90% enterprise adoption by 2028, this category alone could reach $30B+.
6. Enterprise adoption is accelerating. 3.2x increase in enterprise gen AI spending in a single year ($11.5B → $37B). Menlo Ventures describes the application layer as having “quietly achieved escape velocity.” Menlo Ventures
7. Infrastructure capex at 0.8% of GDP is below historical tech boom peaks. Previous technology build-outs hit 1.5%+ of GDP. AI capex may still have room to grow before becoming historically excessive. Goldman Sachs
The Structural Split
Section titled “The Structural Split”The resolution may depend on which layer you’re looking at. CNBC frames 2026 as the year the AI market “splinters”:
- Infrastructure layer: Looks like a bubble. Massive capital investment, uncertain returns, commoditization pressure, circular financing.
- Application layer: Real revenue, rapid adoption, measurable ROI, cumulative growth. “Something entirely different.” CNBC
The market is “becoming increasingly discerning, rewarding companies with clear monetization paths while punishing those with stretched multiples and vague ROI projections.”
Spending composition is shifting: AI services spending is falling from 26% (2024) to 16% (2026) of total AI budgets, while application software and infrastructure software are rising. This suggests enterprises are moving from experimentation (“help us figure out AI”) to integration (“give us AI-powered tools”).
Implications for AI Safety
Section titled “Implications for AI Safety”| Factor | If Revenue Materializes | If Revenue Disappoints |
|---|---|---|
| Research funding | Safety labs remain well-funded; Anthropic’s 200-330 safety researchers sustained | Budget cuts hit safety research first; commercial pressure overrides safety |
| Racing dynamics | Competition intensifies as proven market attracts more entrants | Companies may cut corners on safety to find revenue |
| Capability development | Massive compute investment accelerates capabilities | Compute investment slows, buying more time for alignment research |
| Governance | Policymakers take AI more seriously as an economic force | ”AI was overhyped” narrative reduces political will for governance |
| Talent | AI safety continues attracting top researchers via competitive compensation | Brain drain from safety-focused labs to companies with clearer revenue |
| ConcentrationRiskConcentration of PowerDocuments how AI development is concentrating in ~20 organizations due to $100M+ compute costs, with 5 firms controlling 80%+ of cloud infrastructure and projections reaching $1-10B per model by 20...Quality: 65/100 | Winners consolidate power; 3-5 companies control critical infrastructure | Market correction could redistribute power or destroy value |
The revenue question is not just financial—it determines the pace and character of AI development. A world where AI revenue rapidly materializes is one where capabilities advance faster, competitive pressure intensifies, and the window for safety research may narrow. A world where revenue disappoints may buy more time for alignment work but could also defund the safety-oriented labs.
Key Uncertainties
Section titled “Key Uncertainties”| Uncertainty | Bullish Resolution | Bearish Resolution |
|---|---|---|
| Enterprise ROI | 95% zero-ROI figure reverses as tools mature | AI tools remain nice-to-have, not must-have |
| Price deflation vs. volume | Volume grows 10-100x, overwhelming price declines | Commoditization outpaces demand growth |
| Agentic AI | Unlocks “services as software” — multi-trillion TAM | Agents underperform; trust/reliability insufficient |
| Advertising AI | Extends to all digital advertising ($600B+ market) | Incremental gains plateau; privacy regulation limits targeting |
| Capex discipline | Hyperscalers right-size spending if returns disappoint | Sunk cost fallacy drives continued spending until crisis |
| Circular financing | Virtuous cycle: infra spend → better models → more users → more revenue | House of cards collapses when outside revenue insufficient |
Methodology Notes
Section titled “Methodology Notes”Revenue estimates combine data from company earnings reports, industry analysts (Menlo Ventures, Gartner, Goldman Sachs), and technology press. Categories overlap significantly—hardware revenue is upstream of API revenue, which is upstream of coding tool revenue. The “new AI revenue” estimate of $50-80B attempts to isolate revenue from products and services that would not exist without generative AI, excluding incremental improvements to existing businesses (like ad targeting).
Limitations:
- AI lab revenues (OpenAI, Anthropic) are private company estimates
- “AI revenue” vs. “cloud revenue” boundaries are blurry
- Enterprise ROI data is limited and may be biased by survey methodology
- Capex figures include non-AI infrastructure spending that’s difficult to separate
