AI-generated code failures disrupted corporations worldwide on April 12, 2026. US, European, and Asian firms deployed buggy scripts from GitHub Copilot and Cursor AI. Outages, mishaps, and market jitters followed across time zones.
Crypto markets tumbled in response. CNN's Fear & Greed Index fell to 16, signaling extreme fear. Bitcoin dropped 2.0% to 71,434 USD. Ethereum declined 1.7% to 2,205 USD.
Silicon Valley Payroll Panic
San Francisco-based OmniSoft deployed AI-written payroll code at 9:00 AM PDT (UTC-7). The script doubled salaries for 5,000 employees, per the company statement. Engineers fixed it within hours, but 2 million USD in overpayments reached bank accounts first.
San Francisco Chronicle reporter Mia Chen quoted OmniSoft CTO Raj Patel. Patel blamed an AI-hallucinated multiplier variable. OmniSoft shares fell 4.2% on Nasdaq by noon PDT.

Singapore's TechNova deployed AI code for its e-commerce site at 10:00 AM SGT (UTC+8). Claude AI output triggered a CSS selector error. Every page redirected visitors to Rick Astley's "Never Gonna Give You Up" video.
TechNova's IT team restored the site by 11:30 AM SGT. Google Analytics showed 300% foot traffic surge during the hour. Halted orders cost 500,000 SGD in sales.
Analysts tied this to supply chain effects. TechNova supplies chips to US and European automakers. Delays now threaten Detroit assembly lines.

Tracing AI-Generated Code Blunders
Incidents stemmed from large language models trained on public repos. OpenAI's o1-preview and Anthropic's Claude 3.5 produced faulty snippets, per Snyk error logs.
