Consensus Base Case (Preset)
Soft Landing Odds
10% (By 2031)
Least Likely Near-Term Year 1 (0–12 Mos)
18% Discrete Risk (Now–Oct 2027)

Polymarket prices ~11% year-end crash risk. $800B–$1.2T in hyperscaler CapEx is already contracted, though YoY growth slows from 108% to 47%.

Most Likely Burst Window Years 2–3 (2028–2029)
57% Combined (32% Yr 2 + 25% Yr 3)

OpenAI's $162B cash buffer exhausts in 2028, data-center debt crosses $1.0T, and 2025–26 GPUs hit their 4-year $3.5T impairment cliff.

5-Yr Cumulative Odds By Oct 2031
90% vs. 10% Soft Landing

Includes 55% Selective Reset (80% of leveraged neoclouds consolidated by 2030 per Gartner) and 35% Hard Crash.
