Billionaire investor Stanley Druckenmiller increased his Natera holding to 3.19 million shares, making it his largest position.
Stanley Druckenmiller’s Duquesne Family Office raised its stake in cancer-testing firm Natera (NTRA) to $864.9 million during Q2 2026, making it his largest holding. The position now accounts for 16.6% of his reported portfolio, up from the prior quarter despite shares trading near record highs.
Druckenmiller added 122,700 shares, bringing his total to 3.19 million shares. The move stands out as Druckenmiller, known for macro bets, rarely concentrates holdings in individual healthcare stocks. His prior filings showed smaller allocations to the sector.
The filing, dated August 14, 2026, reflects a long-term conviction in Natera’s growth, diverging from his typical focus on broader economic trends. No immediate market reaction was disclosed in the filing.
