Wall Street’s New Headache: Comparing Apples to Oranges in AI
TREE NEWS reports: In the high-stakes race for AI dominance, the two frontrunners—OpenAI and Anthropic—are now at the center of a financial reporting controversy that has real market consequences. OpenAI projects its annualized revenue will reach or exceed $70 billion by year-end, while Anthropic announced in July that its annualized revenue had already hit $65 billion. However, these headline figures are not directly comparable, and that discrepancy triggered a sell-off in tech stocks on Thursday.
The root of the confusion lies in how each company recognizes revenue. Anthropic counts the full gross sales generated through cloud partners like Amazon as its own revenue. OpenAI, in contrast, uses a net method—only booking the share it actually receives from partners such as Microsoft. This means OpenAI’s reported figure could appear significantly lower than Anthropic’s, even if its underlying business is larger.
Why the Market Cares
Investors attempted to adjust OpenAI’s numbers to match Anthropic’s gross basis, only to find that the resulting estimate was lower than expected, fueling concerns about OpenAI’s growth trajectory. The lack of standardized financial statements from either company has turned annualized revenue (ARR) into a flawed but critical gauge of the trillion-dollar AI boom.
ARR itself is a non-standard, highly malleable metric. It extrapolates a short period’s performance into a full-year figure, giving companies wide discretion. As NYU Stern finance professor Aswath Damodaran put it, focusing on ARR is like “looking at a kindergarten kid’s report card.” More troubling, actual full-year revenue often falls far short of ARR. OpenAI reportedly expects 2026 actual revenue of about $35 billion—half its year-end ARR projection. Anthropic’s 2025 actual revenue was around $4.6 billion, while its announced ARR at the time exceeded $9 billion.
Market Impact: A Black Box That Spooks Investors
With tech stocks near record highs, any sign of slowing sales growth at these AI giants could ripple across the market, especially hitting chipmakers and other AI beneficiaries. Mark Luschini, chief investment strategist at Janney Montgomery Scott, noted: “When such a major market participant is a black box to some degree, investing becomes very difficult.” Uncertainty around OpenAI and Anthropic, he added, “adds another layer to the already persistent and oscillating doubts in the market.”
The opacity is not unique to these two firms. Many star AI startups lean on ARR to showcase growth and justify lofty private valuations. But as Damodaran argues, the debate over ARR technicalities distracts from a more fundamental question: how much real revenue must these companies generate to cover massive expenses and support valuations north of $1 trillion?
What Investors Should Watch
- IPO plans: Anthropic is reportedly preparing to go public. Once listed, both companies will have to file GAAP-compliant financials, making ARR far less relevant.
- Cloud partner disclosures: Microsoft and Amazon may provide clues about the true scale of AI revenue through their own earnings reports.
- Broader tech sentiment: Any negative surprise from AI leaders could exacerbate volatility in an already jittery market.
Until standardized reporting arrives, investors are left navigating a fog of incompatible numbers—and that fog itself is now a market risk.
