Verbatim quote
SpaceX and XAI merging going public in the next couple of months, right? Probably $1.5 to $2 trillion off the top.
Resolution evidence
SpaceX-xAI merger completed Feb 2026 in $250B all-stock deal; valuation of combined entity $1.25T pre-IPO (IndexBox, tech-insider.org). Not strictly an IPO yet but Peter's call materialized.
Predictor: Peter Diamandis
Calibration plot (stated vs observed)
Evidence about this node from Peter Diamandis is multiplied by κ in /api/intake. Lower κ = less weight; floors at 0.10 (effectively silenced) and caps at 1.00 (full weight).
Reference class: ipo_trillion_plus
Trillion-dollar private company IPO at announced valuation within 12 months of S-1
Tetlock-style outside view: at TRF=1 (just predicted), outside view dominates (w_in=0.3). At TRF=0 (deadline), inside view dominates (w_in=1.0). The blend regularizes overconfident inside views toward the historical base rate.
