Helion will scale to 50 gigawatts of fusion-generated power to OpenAI by 2035 — equivalent to more than 7x Grand Coulee Dam output and roughly 1,000 Helion 50-MW reactors.
Predictor: Sam Altman
Prediction text
Helion will scale to 50 gigawatts of fusion-generated power to OpenAI by 2035 — equivalent to more than 7x Grand Coulee Dam output and roughly 1,000 Helion 50-MW reactors. | Helion first commercial reactor beyond Orion
Key catalyst: Helion first commercial reactor beyond Orion
Watch events: Helion path-to-breakeven; manufacturing scale-up announcements
Resolution evidence
Industry consensus: no fusion company has credibly modeled 1,000-reactor manufacturing scale-up within 10 years. Target exists mainly as framework-aspirational ceiling.
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: energy_grid_rebuild_5y
Major grid expansion (>50GW) within 5y of announce
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.
