Why Rai normalizes the raw total
These independently traded market prices add up to 132.2%, rather than 100%. Rai scales each probability proportionally so the outcomes form a complete distribution.
This gap is not a Polymarket fee. It can reflect bid–ask spreads, uneven liquidity, or prices recorded at different times. When the gap is relatively large, normalization can meaningfully affect the estimate.

Assumptions
Configured valuation assumptions
Closed brackets use arithmetic midpoints. Open brackets and the no-IPO scenario use configured values. The no-IPO value is already a current private-company scenario, so it is not discounted again.
Assumptions as of Jul 25, 2026: source and rationale . Scenario inputs translate the source IPO capitalization ladder into current-equivalent dollars. They are not additional market observations.

Important limitations
Scope and limitations
Prediction prices may be illiquid, stale, or distorted. Open-ended brackets require judgment. First-day IPO market capitalization is not intrinsic value, and this model does not account for future dilution, capital raised, or operating fundamentals.
This estimate is not an ownership interest in Strava, an offer to buy or sell securities, or investment advice.
