A quick diagnostic rule for evaluating any contract-based business relationship: in a cost-plus arrangement, the contractor's absolute profit is a percentage of total cost, so the contractor is directly incentivized to make things cost more, not less. Recognizing this structure anywhere in a value chain — as it existed throughout legacy aerospace's subcontractor ecosystem — signals misaligned incentives and inevitable cost bloat. The rule offers a clean action for two roles: entrepreneurs should look to disrupt cost-plus-based industries, while investors should generally avoid backing incumbents locked into that structure.

Core principles
- 01In cost-plus pricing, absolute profit rises with total cost, so incentives point opposite to the customer's interest.
- 02Multiple layers of cost-plus contracts compound into exponential overhead.
- 03A fixed-price, vertically integrated model can be a powerful wedge into a cost-plus industry.
How to run it
- 1
Identify the compensation structure
Check whether the contractor's profit is calculated as a percentage markup on incurred cost.
- 2
Trace the incentive
Ask what behavior this compensation structure rewards — usually higher costs, not lower.
- 3
Check for compounding
Look for multiple layers of subcontractors each applying the same cost-plus markup, which compounds costs exponentially.
- 4
Choose your action
As an entrepreneur, build a fixed-price/vertically integrated alternative to disrupt the industry; as an investor, avoid incumbents dependent on this model or back the disruptor instead.
In the wild
Pre-SpaceX, government rocket contracts flowed through primes like Boeing and Lockheed down through many subcontractor layers, each paid a percentage of cost, so nobody in the chain was incentivized to reduce spending.
→ Costs ballooned to the point that a rocket's raw materials represented roughly 2% of its final price.
Common mistakes
Treating cost-plus as a neutral industry norm
Because it's common, it's easy to overlook how directly it misaligns incentives against the paying customer.
Only checking the prime contractor
The real damage often comes from subcontractors-of-subcontractors, each layering on their own cost-plus markup.
Is it for you?
Best for
Investors and operators evaluating whether to enter, fund, or disrupt a contract-driven industry.
Not ideal for
Situations where cost variability is genuinely unpredictable and no fixed-price alternative is feasible (e.g., some early-stage R&D contracts).
From the transcript
“If you ever, as an investor or an operator encounter a situation where there is a cost plus contract uh as a way of doing…”
“Because with a cost plus, literally, it's you get a there's the cost of what it costs to make something, and then the contractor makes…”
