Real options & pretotyping
Real options thinking, applied to AI bets
Finance already has the right mental model for uncertain AI investments. It’s called real options, and pretotyping is how you buy them cheaply.
The short answer
A real option is the right, but not the obligation, to invest further in a project as uncertainty resolves. Applied to AI, it means funding bets in small, evidence-gated stages rather than one all-in commitment. Pretotyping is how you buy that option cheaply: a small spend on behavioural evidence that earns you the right to invest more, or walk away, before the big money is committed.
- Each AI bet is funded as a staged option, not a single up-front commitment.
- A pretotype is a cheap option: small cost now for the right to decide later with evidence.
- The value of an option rises with uncertainty, exactly the condition AI investments face.
- Killing a bet early is exercising your right not to invest, and it protects capital.
Why all-in AI funding destroys value
When a board funds an AI initiative to completion up front, it pays the full cost regardless of what it learns along the way. If the bet fails, and most do, RAND puts the AI project failure rate above 80%, twice that of non-AI IT, the entire investment is lost. That is the opposite of how you should invest under deep uncertainty.
Real options theory says: under uncertainty, the right to wait and learn has value. You pay a little to keep the option open, then commit fully only when the evidence justifies it. AI, where value is genuinely unknown until tested, is the textbook case for this.
Pretotyping is buying the option
A pretotype is the cheapest possible option on an AI bet. For a small, fixed cost you run a behavioural test that tells you whether to invest further. If the signal is strong, you exercise the option and fund the build. If it’s weak, you let the option expire and keep your capital.
This reframes the spend on a pretotype. It isn’t overhead before the “real” work, it is the purchase of decision rights. You are paying to make the next, much larger decision under far less uncertainty.
Staging an AI portfolio as options
Across a portfolio, the implication is powerful. Instead of a handful of large, all-in AI bets, you hold many cheap options and exercise only the few that prove out:
- Buy options widely, pretotype many candidate bets for a small total cost.
- Exercise selectively, fund the build only on bets with strong behavioural evidence.
- Let weak options expire, stop bets that fail their pretotype without further loss.
- Re-price continuously, as evidence arrives, re-rank the portfolio and reallocate.
The board-level payoff
Managing AI as a portfolio of real options is what lets a board move fast and stay disciplined at once. It funds learning cheaply, concentrates capital on proven bets, and treats a kill decision as a feature, not a failure. That is the financial logic underneath every AI Bets Audit we run.
