 Top 3 Insider Purchases of the Week: Where Billions Are Flowing While the market fluctuates, major players are quietly building positions. I analyzed fresh OpenInsider data from May 11–13, 2026 — here's what caught the attention of smart money. Republic Services ($RSG) — $100.5 million Cascade Investment (Bill Gates' fund) acquired 499,150 shares at $201.40. This is not speculation — it's a 0.5% increase in their stake in the waste management giant. A bet on stable cash flow amid uncertainty. Total fund position: 110 million shares. Artiva Biotherapeutics ($ARTV) — $75 million Ra Capital Management increased its stake by 66% — buying 6.5 million shares at $11.52. A biotech focused on CAR-T therapy. Higher risk, but multiple upside if clinical trials succeed. Odyssey Therapeutics ($ODTX) — $25 million TPG (former 10% shareholder) returned with a purchase of 1.39 million shares at $18. Another early-stage biotech project. TPG is known for entering before the hype. What this means: — Large funds are diversifying: defensive assets (RSG) + high-risk biotechs — Average purchase prices are below current market prices — insiders consider the stocks undervalued — TKO Group Holdings ($TKO) purchases by CEO and CFO total $4.5 million — management is voting with their money for their business Conclusion: Insiders are not expecting a recession — they are choosing specific stories with clear fundamental logic. For retail investors, this is a signal to look into the waste management and biotech sectors. Data: OpenInsider, 05/13/2026. Not investment advice.
