When this applies
when diagnosing which layer of a technology value chain is actually capturing the economic surplus it creates
The takeaway
In a value chain, the layer capturing the most economic surplus is not necessarily the one creating the most technical innovation — surplus tends to flow to whichever layer has the least competitive pressure or most differentiated downstream application.
Why it works
End users like Jane Street or Meta extract far more value from using a model (trading edge, ad engagement gains) than the model provider captures in subscription/API revenue, because competitive pricing and demand elasticity keep model-layer margins below the user's realized value.
One level up
Always map 'who creates value' separately from 'who captures value' in a stack — the two routinely diverge, and strategy should target the capture layer, not just the creation layer.
Where it stops holding
This stops working when model providers develop true pricing power (e.g., exclusive capability advantage) that lets them capture a larger share of downstream value, which Patel notes may be starting to happen as labs reallocate compute inward.
Detail
rule: Expect the most value to accrue to end users and scarce upstream hardware/components, not necessarily to the most visible 'AI product' layer.
threshold: Jane Street reportedly captures $300-500M/megawatt in value versus Anthropic's ~$100M/megawatt realized revenue from serving Jane Street.
rationale: Jane Street is capturing $300,000,000 per megawatt or $500,000,000 per megawatt... that's the one saving grace is that the rest of the economy maybe profits so much more from Anthropic.
In their words
But at the end of the day, the reason they've gone to a $100,000,000 per megawatt is because Jane Street is capturing $300,000,000 per megawatt or $500,000,000 per megawatt.
