OpenAI's operating losses ballooned to $10.9 billion in Q3 2026 even as revenue surged 50% to $10 billion, according to documents viewed by The Wall Street Journal. The widening deficit comes as investors scrutinize AI firms' finances ahead of Anthropic's $26 billion IPO.
TL;DR
- OpenAI's operating losses grew to $10.9B in Q3 2026 despite revenue rising 50% to $10B.
- Anthropic's $26B IPO filing reveals 825M shares priced at $70–$78 each, with $26B in non-voting shares sold to Google, Nvidia, AMD, and Microsoft.
- Investors are weighing the sustainability of AI spending as losses deepen and IPOs like Anthropic's set the stage for market volatility.
What happened
OpenAI reported a 50% revenue jump to $10 billion in Q3 2026, but its operating losses widened to $10.9 billion from $10.1 billion the prior quarter, according to The Wall Street Journal. The adjusted operating margin improved to -109% from -150%, yet the deficit still grew in absolute terms.
The company's financial disclosures arrive as investors dissect the unit economics of top AI labs. Anthropic's upcoming IPO is being treated as a bellwether for the sector's ability to sustain massive capital outlays.
Anthropic filed to sell 825 million shares at $70–$78 each, aiming for a valuation near $1.4 trillion. The filing also disclosed a $26 billion private placement to seven tech giants—Google, Nvidia, AMD, Microsoft, and others—all of whom are investors or suppliers to Anthropic.
Analysts warn the IPO could test investor appetite for AI infrastructure bets after midterm election outcomes raised regulatory uncertainty around AI development.
Why it matters
For developers and startups, OpenAI's widening losses underscore the unsustainable unit economics of scaling frontier models. High revenue growth does not automatically translate to profitability, raising questions about long-term viability of current AI business models.
Investors are now forced to confront the trade-off between growth and burn rates. Anthropic's IPO will serve as a critical test case: if the market accepts a $1.4 trillion valuation despite $26 billion in pre-IPO funding, it may validate continued aggressive capital deployment. If not, the AI funding boom could face a correction.
The $26 billion private placement by major tech suppliers signals deep strategic interest but also potential overreliance on a handful of incumbents. This concentration risk could limit competition and innovation if smaller players struggle to secure similar backing.
Regulatory scrutiny—especially from a Democratic-controlled Congress—adds another layer of risk. Policy shifts could slow down capital flows, making it harder for AI labs to maintain their current pace of investment.

Context
OpenAI and Anthropic represent two of the most closely watched AI labs as the industry transitions from research to commercialization. Both have raised billions to train large models, but profitability remains elusive despite rapid revenue growth.
The AI infrastructure stack—dominated by Nvidia's chips, hyperscaler cloud capacity, and specialized AI services—is increasingly concentrated among a few players. This concentration is mirrored in the IPO's private placement, where major suppliers are also investors.
Anthropic's IPO comes amid broader market volatility tied to AI valuations. Nvidia's CEO Jensen Huang recently faced scrutiny over a spy scandal, further highlighting the sensitivity of AI-linked stocks to reputational and regulatory risks.
