How history calculations work

The performance view sets each available series to 100 at its first observation in the selected timeframe. The Rai Index compounds the equal-weighted daily returns of every other company available in consecutive snapshots; it excludes the company being viewed.

QQQ is the Invesco QQQ ETF used as a public-market technology benchmark. Rai stores the raw daily close from Alpha Vantage; non-trading days carry the latest prior close. This is a price-return comparison, not a dividend-adjusted total return.

Rai calculates the annualized sample standard deviation of daily logarithmic changes over the latest 30 days. It waits for at least seven daily changes. This describes movement in Rai’s model estimate, not the risk of a traded security.

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.

  1. 01

    Select market quotes

    Use one selected Polymarket quote for each configured NPM Price threshold

    7 contracts
  2. 02

    Fit a monotone curve

    The chance of exceeding a higher value cannot exceed the chance of exceeding a lower one

    Equal-weight isotonic fit
  3. 03

    Difference adjacent thresholds

    P(band) = P(above lower) − P(above upper), then weight each band

    Translate the peak to current value

    Peak value ÷ (1 + 10.0%)^0.39

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.
