The $4 billion business behind drug testing
About this video
Sam and Shaan explore the supply chain and economics of lab monkeys used in pharmaceutical testing. They discuss how COVID-driven demand caused monkey prices to skyrocket from $2,000 to $50,000 each, China’s sudden export halt, and how companies like Charles River Labs dominate the preclinical testing market.
Key takeaways
- Sam notes that the US imports roughly 20,000 monkeys annually for testing, with prices surging dramatically during COVID as vaccine development accelerated demand
- When China—which supplied 60% of the world’s non-human primates—stopped exports, Cambodia and Vietnam stepped in as alternative suppliers, but prices remained elevated at $50,000 per monkey
- Sam observes that Charles River Labs has built a near-monopoly in preclinical testing services, working with 80% of biotech companies and testing 80% of drugs that reach market, claiming $4 billion in annual revenue
