What if Copper interconnect wall forces costly optical migration?
Copper hits its bandwidth-distance limit inside AI racks sooner than planned, forcing an expensive accelerated move to optical interconnect and pressuring system margins.
Every number ships with its receipt — the odds, the range, the precedents, and a public grade at Reality Check. The statistical machinery that produces it is proprietary.

Resolution timeline — how this probability is moving
Our model's odds (electric blue) over time vs the market's (Polymarket, amber), from the past toward the 1–3 years horizon. Each dot is a real macro event that nudged the probability — green pushed it up, red pushed it down. Tap a dot for the source. Loading the probability audit trail…
What it would mean
If this plays out, it is a mixed shock. Copper hits its bandwidth-distance limit inside AI racks sooner than planned, forcing an expensive accelerated move to optical interconnect and pressuring system margins. The trigger decomposes into signed root‑shocks — AI capex ▲ · Risk appetite ▼ · Semiconductor supply risk ▲ — which propagate through our causal graph to the markets below.
