Corvex Dumps $202M in Illumina; Uber COO Buys the Dip

Activist fund Corvex Management filed disclosures showing it sold $202.8 million worth of ILMN shares across 40 transactions, with trades running from early September and reported to regulators on 4 September 2026. The exit is striking given Corvex holds a board seat at the genomics company. The sales ranged from $1.5 million to $21.9 million per transaction, suggesting a deliberate wind-down of the position rather than a one-off event. Illumina carries a market cap of $40.5 billion and short interest sits at 5.8% of free float.

On the buying side, UBER President and COO Andrew Gordon MacDonald filed on 8 September, disclosing open-market purchases of 70,000 shares for a combined $5.3 million at prices around $75.65 to $76.44. Open-market buys by a C-suite executive carry more weight than option exercises or awards. MacDonald now holds a meaningful personal stake at current prices.

NMIH CEO Adam Pollitzer filed a $7.7 million sale of 172,706 shares at $44.86 on 4 September. No 10b5-1 plan flag was recorded in the data, making it a discretionary sale worth monitoring.
