Gates Loads Up on Waste, Uber COO Buys Dip

Bill Gates filed disclosures on September 1–3 showing he spent over $241 million buying Republic Services shares. The trades ran from August 28 to September 2. Gates snapped up roughly 1.09 million shares across multiple transactions, cementing his position as the waste-management giant's largest individual backer. It is a steady accumulation pattern, not a one-off bet.

On the corporate side, Uber President and COO Andrew Gordon MacDonald filed on September 8. He bought 54,325 shares for $4.1 million on September 4. Open-market purchases by C-suite officers carry strong signal — MacDonald is putting his own cash to work, not exercising options.

In Asia, Li Ning founder Li Ning's holding vehicle, Viva China Holdings, filed on September 7 disclosing it bought $160.5 million worth of shares between August 27 and September 3. The sportswear brand has struggled with slowing demand. The founder buying this aggressively across six trading days is a notable vote of confidence.

On the sell side, NMI Holdings CEO Adam Pollitzer filed a $7.7 million sale on September 4. Warner Bros. Discovery Director Kenneth Lowe sold $5.7 million worth of shares on September 3. Tenet Healthcare COO Lisa Foo sold $6.4 million on August 31.

The clearest bullish signal this period remains Gates steadily accumulating Republic Services. The Uber COO buy is the most interesting C-level open-market trade among US names.
