The author has extensively explored Artificial Intelligence's business implications this year, from market potential and economics to its impact on companies and indices. The recent filing of Anthropic's IPO prospectus prompted a deeper valuation analysis. The prospectus, though lengthy, offers insights into Anthropic's rapid revenue growth, which has recently seen a slowdown due to competition and constraints.Despite significant operational losses, Anthropic reports improving efficiency and a positive trend towards profitability, with compute costs decreasing as a percentage of revenue. The company has made substantial future commitments for compute power, which is crucial for growth but represents a significant financial obligation. Anthropic faces operating and regulatory risks, including potential revenue cyclicality and default risk due to its large financial commitments.However, a substantial cash balance, bolstered by the IPO, provides a buffer against these risks. The author cautions against focusing solely on historical prospectus data, likening it to a kindergartner's report card for assessing long-term value. They advise against getting lost in conspiracy theories or suspecting accounting fraud, emphasizing self-interest and accounting discretion as common business factors.Ultimately, Anthropic's valuation hinges on future market size and its market share, which depends on AI's role as a productivity tool or job displacer. The author believes AI will disrupt industries and displace highly paid employees, projecting a market size of $5 trillion or more. This projection is based on the potential for AI to impact white-collar jobs globally across multiple industries.
