PHYSIX OBSERVATION

The AI industry is undergoing a critical shift from 'cash-burning training' to 'profitable inference.' Cloud vendors are collecting high tolls through their compute monopolies, while model companies achieve financial health via high-margin API businesses. However, investors must be wary that current profits may be inflated by accounting differences and short-term supply-demand mismatches. As independent compute facilities come online after 2028, the profit distribution landscape between cloud giants and model developers could be restructured; investors should look past reporting noise to understand the true unit economics.
