Cumulative threshold distribution
Each contract prices the chance that Stripe reaches at least its threshold under the configured NPM Price definition. Adjacent fitted probabilities are differenced to avoid double-counting. Read the source rules .

Calculation details
Threshold-curve calculation
The source distribution describes the highest valuation reached by the deadline. The current-equivalent figure is reported separately as an assumption-driven scenario.

Select market quotes
Use one selected Polymarket quote for each configured NPM Price threshold
- 02Equal-weight isotonic fit
Fit a monotone curve
The chance of exceeding a higher value cannot exceed the chance of exceeding a lower one

Translate the peak to current value
Peak value ÷ (1 + 10.0%)^0.21
Assumptions
Lower- and upper-tail assumptions
The lowest band is anchored at a known valuation floor. Closed bands use midpoints, while the open upper tail needs an explicit representative value.
Assumptions as of Jul 30, 2026: source and rationale . The floor, open tail, and deadline-peak translation rate are explicit scenario inputs rather than prediction-market facts.

Sensitivity
Growth-rate and upper-tail sensitivity
These checks vary the distribution’s open lower and upper tails. The current-equivalent bridge is an assumption-driven input to the Rai current valuation, not a direct market quote.

Important limitations
Scope and limitations
The contracts resolve on the highest qualifying non-public-market or public-market valuation observed before the deadline. The estimate is path-dependent and should not be read as a terminal, intrinsic, year-end, or current value. Thin markets, correlated contract errors, the chosen floor, and the open upper tail can all affect the result.
This estimate is not an ownership interest in Stripe, an offer to buy or sell securities, or investment advice.
