Prediction text
Current market panic over AI compute and power will follow the historical pattern 'shortage leads to oversupply' — trillions flowing into data centers, GPU manufacturing, and energy procurement will ultimately crash the marginal cost of both compute and power. | First hyperscaler capex-growth deceleration
Key catalyst: First hyperscaler capex-growth deceleration
Watch events: GPU spot-price softening; hyperscaler capex guidance revisions; IRENA / IEA deflation curves
Resolution evidence
Historical precedents (1990s fiber glut, 2000s VC overbuild) validate pattern; contemporary analogues visible in 2026 H2 GPU secondary-market softening and announced 2027-28 hyperscaler fab capacity additions.
Predictor: Marc Andreessen
Evidence about this node from Marc Andreessen 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
This node isn't linked to a reference class. The Bayesian update applies without outside-view blending.
