Predictor: Sam Altman
Prediction text
Stargate is a $500 billion multiyear capex program for distributed AI data-center construction (2025-2028, with Trump administration partnership). | Stargate site milestones 2026-2027
Key catalyst: Stargate site milestones 2026-2027
Watch events: Stargate site groundbreaking announcements; OpenAI infrastructure spend disclosures
Resolution evidence
Stargate announced Jan 2025 with SoftBank/Oracle/MGX. Abilene TX site under construction Q4 2025. First buildings reportedly online 2026.
Predictor: Sam Altman
Calibration plot (stated vs observed)
Evidence about this node from Sam Altman 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: hyperscaler_capex_forecast_2y
Hyperscaler/AI infra capex forecast within 1-2y forward window meets-or-exceeds stated headline number
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.
