Anthropic brings Wall Street an AI bull case

axios.com

AI companies for years have promised that smarter models would be worth the staggering cost to build them. Anthropic on Wednesday made that case in cash. The company presented eye-popping financials to investors, saying it was cash flow positive in the third quarter, with revenue surging nearly 50% to $16.8 billion compared with the April-to-June period. Why it matters: As Wall Street broadly spent the day fearing an AI bubble, Anthropic offered what investors have been desperate to see: evidence that frontier AI can be a sustainable business . State of play: The S&P 500 fell by more than 1% for the first time in 53 sessions, while Anthropic showed off a balance sheet that promises profitable AI, sources told Axios. Zoom in: Consider just one of the stats reported by Anthropic: The company is cash flow positive even as some of the world's most profitable companies are struggling to keep their AI spending in check. For context, Google parent Alphabet, long a money-printing machine, turned free cash flow negative in its second quarter as AI infrastructure investment soared. Investing gurus — especially those focused on the frothiness of companies relative to their underlying value — have long seen free cash flow as a gold standard for the long-term health of a business. Anthropic, a much younger company competing in the same expensive AI race, says it was cash flow positive in the third quarter. The Anthropic figures were first reported by the Financial Times . Yes, but: The company's blistering pace of growth appeared to slow compared with the difference between the first and second quarters, when sales more than doubled. Few investors saw growth as likely to continue at that pace, especially while the company faced ferocious competition from OpenAI. Between the lines: Anthropic's latest financial disclosures reinforce what analysts and investors have been telling Axios: The company's early bets on frontier intelligence and enterprise adoption are translating into meaningful financial gains that put it on track for the largest IPO in history. Some investors expect it to reach a $2 trillion valuation. Flashback: Anthropic's early bets on coding expertise, business customers and spending discipline have paid off. Claude Code, a viral hit that brought users to Anthropic in droves, reached an estimated annualized revenue of $6 billion to $7 billion by late summer, per Bloomberg Intelligence. Customers have generally been reluctant to switch once they've adopted it, per PitchBook data. Anthropic charges roughly 20% to 30% more than competing models, according to Bloomberg Intelligence, a pricing power that BI's global head of tech research Mandeep Singh views as sticky given the level of intelligence customers get from Anthropic tools. Anthropic's API business generates an estimated 90% of revenue using just 58% of the computing power needed to run its models, resulting in an estimated 92% gross margin before certain expenses, per SemiAnalysis. Reality check: Anthropic hasn't solved every financial challenge associated with the AI buildout. The company still faces enormous training costs and stock-based compensation expenses, which could weigh on its underlying profitability. And Anthropic faces more than $500 billion in planned infrastructure and computing spending over the next decade. Its premium pricing could also face pressure from increasingly capable, cheaper open-weight models. What we're watching: Whether Anthropic can sustain its technological and financial advantages as it expands its frontier intelligence offerings into additional niche areas beyond coding. The company's total addressable market will be a critical figure in its IPO paperwork. One Anthropic investor said they're eager to see how the company thinks its leading-edge intelligence can translate into breakthroughs in drug discovery and other businesses beyond software. The bottom line: Anthropic is showing Wall Street how frontier intelligence can turn into an actual business right when investors needed some good news.
