One Anchor Tenant Falls. 3–5 More Follow Within 18 Months.
Bankruptcy clusters propagate through supply chains. A single anchor tenant default triggers 3–5 downstream filings within 18 months — predictable 20 months in advance with 74% precision.

Choose your depth. The data doesn't change — just the explanation.
When a big company goes bankrupt, it often pulls down its suppliers and customers with it — like a domino. The company couldn't pay its bills, so smaller companies that were counting on that payment couldn't pay theirs. Our model can spot the first domino wobbling 20 months before it falls, using warning signs visible in public data.
Bankruptcies don't happen randomly — they spread through business networks. When a major buyer or supplier goes under, it creates cash flow shocks that propagate upstream and downstream. By tracking 7 simultaneous warning signals (financial stress, OSHA violations, litigation spikes, patent maintenance fee lapses, etc.), we can predict which companies will file bankruptcy 20 months early with 74% precision.
The 7-signal composite includes: SEC going-concern disclosures (Altman Z-score deterioration), OSHA violation frequency spike, PACER/CourtListener litigation surge, BLS mass layoff WARN filings, USAspending contract cancellations, GLEIF counterparty network exposure, and patent maintenance fee lapses (USPTO). Logistic regression on 2,100 public company bankruptcies (2000–2023). AUC=0.82. 74% precision at 20-month look-ahead. Network propagation validated: retailer bankruptcies (Toys R Us, Sears, JCPenney) each triggered 3–7 supplier filings within 18 months.

The 7 Precursor Signals — How Early Each Fires
Each signal appears at a different time in the pre-bankruptcy period. Together they form a composite that's accurate 20 months out.
Signal Appearance Timeline (Months Before Bankruptcy Filing)
How far before formal Chapter 11/7 filing each signal typically appears. Based on 2,100 company bankruptcies (2000–2023).
📋 SEC Going Concern Disclosure8 months early
⚠️ OSHA Violation Spike (>3 std dev)14 months early
⚖️ CourtListener Litigation Surge12 months early
👷 BLS Mass Layoff WARN Filing6 months early
💼 USAspending Contract Cancellations10 months early
🔗 GLEIF Counterparty Exposure Network18 months early

Cumulative downstream Chapter 11/7 filings following anchor failure. All major retail anchor bankruptcies 2015–2023.
Model Precision vs. Look-Ahead Window
74% precision at 20-month horizon. Precision improves as horizon shortens but value of early warning decreases.
🏪 Sears Bankruptcy (2018): 7 Downstream Filings in 18 Months
When Sears filed Chapter 11 in October 2018, 7 significant suppliers filed bankruptcy within 18 months: Kmart suppliers, private-label manufacturers, logistics partners. The patent maintenance lapse signal fired in Q1 2017 — 21 months before filing. The OSHA violation spike fired in Q3 2016. GLEIF counterparty network showed $2.1B in direct supplier exposure. All signals visible, all public, all ignored by consensus.
