Anthropic just released its public IPO filing, but an eye-popping figure leaked about a week earlier. The massive company that develops the Claude AI models reported a net loss of $80.7 billion for the first six months of 2026. That is almost five times the $16.3 billion of revenue it reported for the same period.
At first glance, this might look like a major red flag for investors. But if you look a little deeper into the filing, you'll see that Anthropic earned an adjusted profit of $2.7 billion for the first half. But how can this be? Here's what investors need to know about the gap between the company's reported loss and how much money it is actually making.

Where Anthropic's $80.7 billion "loss" came from
Here's how the math works. I mentioned earlier that Anthropic reported $16.3 billion in revenue for the first half of 2026. The company also spent about $17 billion running the business, resulting in an operating loss of about $700 million ($693 million, to be exact). That's about 4% of revenue and is a far more reasonable loss than the headline number implies, especially for a rapidly growing company like Anthropic.
In addition, Anthropic holds about $131.7 billion of cash and short-term investments on its balance sheet, and the company generated $1.1 billion of interest income. So, this would actually put the profitability slightly in the black.
So, where did the $80.7 billion loss come from? Mostly, there was a $72.4 billion accounting charge related to changes in the fair value of convertible notes. In a nutshell, convertible notes are a form of debt that holders can elect to convert into stock at a predetermined conversion price. So, because Anthropic's valuation increased sharply this year, those notes became a lot more valuable, and accounting rules require the company to record this change in value as an "expense."
In addition, there was an additional $8.8 billion charge listed as "other expense." This is another non-cash charge tied to Anthropic's financing. Between these two charges, that's more than an $81 billion accounting "charge" that didn't actually cost Anthropic any money at all.
How much Anthropic is really earning
As mentioned, Anthropic reported a $693 million operating loss for the first half, but when adjusting for certain non-cash items, the company had a $1.6 billion operating profit. This is an operating margin of nearly 10%, and from a company that grew second-quarter revenue by 1,368% year-over-year.
There's a good case to be made that Anthropic's profits could rise significantly in the near future. Its computing costs as a percentage of revenue have fallen dramatically over the past year, and newer models (like Claude Opus 5.5) are far cheaper to use than their predecessors.
Of course, adjusted profitability metrics exclude certain non-cash costs that investors should consider. For example, Anthropic's stock-based compensation expense was $2.2 billion in the first half, and although this isn't a cash expense, it dilutes existing shareholders' ownership.
It's also worth noting that Anthropic's reported revenue can look larger than it is. Specifically, many customers buy Claude through the cloud platforms run by Amazon (NASDAQ:AMZN), Microsoft (NASDAQ:MSFT), and Alphabet (NASDAQ:GOOGL)(NASDAQ:GOOG), but Anthropic contracts with the customers directly and pays these companies a fee.
The bottom line
The key takeaway for investors is that Anthropic isn't losing anything close to $80 billion running its business. Rather, it's far closer to breakeven, even on a GAAP operating basis, than many investors might have thought, and these large convertible note charges should go away after the notes convert to stock after the IPO is finished. One thing we don't yet know is Anthropic's IPO valuation, but we now know this is a fast-growing business that is getting very close to profitability.
Missed AI’s "Act 1"? Act 2 Could Be 14x Bigger
Most investors think they missed the AI boat because they didn't buy Nvidia in 2005.
But according to our analysts, we’re only at the end of "Act 1"—the R&D phase. "Act 2" is the global rollout, a massive technology build-out that Google’s CEO says could be more profound than fire or electricity.
While everyone watches the chip designers, one "backbone" company provides the critical technology that Nvidia and AMD literally cannot function without. We’ve detailed this under-the-radar player in our new AI Playbook.
