Anthropic is targeting a $2 trillion valuation in its upcoming IPO, but a new report reveals that its most expensive AI model, Fable 5, is struggling to gain traction with customers. The company's growth strategy is now under scrutiny as businesses opt for more affordable alternatives.
TL;DR
- Anthropic is preparing for a $2 trillion IPO, with projected 2028 revenue of $190 billion to $200 billion.
- Spending on Anthropic's most advanced model, Fable 5, has plateaued at 11%, while its cheaper Opus 5 model is gaining more traction.
- The shift towards 'good enough' AI models could impact Anthropic's growth trajectory and IPO valuation.
What happened
Anthropic, a leading private AI company, is reportedly planning an October IPO with a valuation of $2 trillion or more, according to 247wallst.com. This valuation would surpass the record set by SpaceX, which went public in June at $1.77 trillion. Anthropic's annualized revenue run rate has seen significant growth, jumping from roughly $9 billion at the end of 2025 to $47 billion in May and more than $65 billion by the end of July. The company projects roughly $190 billion to $200 billion of revenue in 2028.
However, a report from the Financial Times introduces a potential challenge to Anthropic's growth strategy. Spending on Anthropic's most powerful and expensive model, Fable 5, has plateaued at around 11% of total spending on its tools more than two months after its launch. In contrast, Anthropic's cheaper Opus 5 model has surpassed Fable 5 in business spending shortly after its late-July release. This trend suggests that customers may be opting for more affordable AI solutions that are 'good enough' for their needs.
Why it matters
For AI/ML developers and startup founders, this news highlights the increasing price sensitivity among businesses when it comes to AI adoption. The trend towards cheaper, 'good enough' AI models could impact the competitive landscape and force companies to focus on cost-effective solutions. For tech investors, the news raises questions about the sustainability of high valuations for frontier AI companies, particularly if customers are not willing to pay a premium for the most advanced models.
The shift in customer preferences could also impact the growth trajectories of other AI companies, particularly those relying on high-margin, premium models. Competitors like OpenAI, with its GPT 5.6 models priced below Fable 5, and open-weight models from China, add to the price pressure. The real risk for Anthropic and similar companies is whether AI progress will translate into more customer spending or simply better performance at lower prices.

Context
The AI market is evolving, with businesses now focusing on the practical value of AI models rather than just their capabilities. This shift is crucial for frontier AI companies that have built their valuations around significant investments in chips, data centers, and model training. Anthropic's situation underscores the importance of balancing innovation with cost-effectiveness in the AI industry.
The trend towards 'good enough' AI models reflects a broader industry shift towards efficiency and practicality. As more companies enter the AI market with competitive offerings, the pressure on premium pricing models is likely to increase.
