OpenAI Annualized Revenue Falls $20 Billion Short of Forecast 2026

OpenAI's annualized revenue has come in $20 billion below expectations, according to a report from Reuters. The shortfall has rattled investors and reignited a pressing question: is investing in AI actually profitable?

At the end of September, Sam Altman had told investors that OpenAI's annualized sales would be around $70 billion. New figures now put that number at roughly $50 billion—a significant gap that has sparked a bearish storm across the tech sector.

What Exactly Happened with OpenAI's Revenue Forecast?

The discrepancy emerged after the Financial Times, Reuters, and other outlets published estimates based on sources close to OpenAI, pegging annualized revenue at nearly $70 billion. That figure was widely circulated and factored into investor expectations.

Now OpenAI has confirmed to its investors that the actual annualized revenue is closer to $50 billion, as reported by Reuters. The $20 billion difference is not trivial—it represents a massive miss against the company's own guidance.

Why the Numbers Don't Match Up

According to the Financial Times, the gap stems from attempts by OpenAI investors to directly compare the company's annualized revenue with that of Anthropic. The problem is that the two companies calculate this metric differently, making a direct equivalence impossible.

Anthropic includes revenue from certain cloud partnerships and other arrangements in its annualized figures, while OpenAI's methodology appears to exclude or handle these differently. This lack of standardization has led to confusion and, ultimately, disappointment.

Why This Matters for Investors and the AI Industry

Wall Street dislikes surprises, and even a minor deviation from estimates can keep investors up at night. This week, it was OpenAI's turn—and the surprise was not a pleasant one.

The shortfall has cast a shadow over the entire tech sector, as investors question whether the hype around AI translates into real, sustainable revenue. The news has also intensified scrutiny on how AI companies report their financials.

• Investor confidence: The $20 billion miss undermines trust in OpenAI's projections and could make future fundraising harder.
• Valuation concerns: OpenAI's lofty valuation depends on hitting aggressive revenue targets; a shortfall may force a reassessment.
• Sector-wide impact: Other AI companies may face tougher questions from investors about their own revenue metrics.
• Methodology scrutiny: The lack of standardized reporting for annualized revenue is now a red flag for analysts.

How Do OpenAI and Anthropic Compare on Revenue Reporting?

The confusion highlights a broader issue in the AI industry: there is no uniform standard for calculating annualized revenue. Companies use different definitions, making comparisons misleading.

The table below summarizes the key differences based on available information.

As the table shows, OpenAI's reported figure is significantly lower than what investors had been led to expect. The difference in methodology between the two companies only adds to the confusion.

What This Means for the Future of AI Investment

The revenue shortfall is a wake-up call for investors who have poured billions into AI startups. It suggests that the path to profitability may be longer and more uncertain than previously thought.
