## AI Infrastructure Buildout
The AI infrastructure buildout, driven by OpenAI and Anthropic, is the largest in U.S. history by GDP share.
## Unprofitable Models
Both OpenAI and Anthropic are unprofitable, relying on massive future capital raises and circular financing.
## End of Boom Cycle
Historical tech buildouts suggest investors in key infrastructure rarely benefit, while end-users eventually reap the rewards.
## Risk of Recession
If OpenAI or Anthropic fails, the interconnected AI ecosystem could trigger a significant market downturn and potential recession.
## Key takeaway

OpenAI and Anthropic's unprofitable AI infrastructure buildout risks triggering a market downturn if they fail, ending the U.S. tech boom cycle.
