What if widely implanted brain chips malfunction and cause seizures?
Mass BCI malfunctions causing seizures and recalls trigger a liability crisis in a small neurotech cohort — short the device names, not the broad semis complex; the Nvidia/Nasdaq cascade overstates reach. Rhymes with the Abiomed/Medtronic recall drawdowns and earlier ICD-recall episodes that hit the issuer, not tech. Real transmission is product-liability and a chilling of neurotech funding; macro spillover minimal.
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.

What it would mean
If this plays out, it is a mixed shock. Widely implanted BCI device malfunctions cause seizures and recalls, triggering liability crisis and neurotech-sector selloff. The trigger decomposes into signed root‑shocks — Risk appetite ▼ — which propagate through our causal graph to the markets below.
