Tempus AI (TEM) stock had its best day on record on Tuesday after the medical tech company launched an AI-powered health concierge and former ༒Ho♒use Speaker Nancy Pelosi revealed she's bet on the stock.

Tempus on Tuesday morning launched olivia, “an AI-enabled personal health concierge app designed to empower patients by bringing their health-related data into one central location and leveraging advanced AI to provide actionable insights.” 

The app, according to a press release, can integrate with Apple Watch and Google Fit to track a user’s day-to-day health, summarize their clinical history, and transcribe doctors’ appointments. Tempus CEO Eric Lefkofsky emphasized olivia “goes beyond organizing information; it’s a proactive partner" of patients navigating their health and care. 

Tempus shares jumped 35.5% on Tu♈esday, the biggest one-day jump since the stock debuted in June.

The market’s reaction to olivia could reflect a changing AI narrative on Wall Street. Since 2022, the Magnificent Seven and other companies vital to the buildout of AI infrastructure have been the main beneficiaries of the AI craze. In November, Goldman Sachs analysts predicted the AI revolution would 澳洲幸运5官方开奖结果体彩网:enter "Phase 3" this year, during which a wider variety of companies will see artificial intelligence meaningfully contribute to their top and bottom lines. They expect software companies in p𝓀articular to benefit as they launch AI agents like olivia—digital assistants capable of greater autonomy than chatbots like ChatGPT.  

The Pelosi Boost

Tempus stock also got a boost from a routine stock trading disclosure from former House Speaker Nancy Pelosi, who on January 14 purchased 50 call options expiring in January 2026 with a 澳洲幸运5官方开奖结果体彩网:strike price of $20. Tempus stock closed just under $🍨32 on the day of Pelosi’s trade, and on Tuesday closed at $47.64. 

Pelosi, whose husband owns a venture capital firm, is one of Washington's 澳洲幸运5官方开奖结果体彩网:most prolific traders. An E🔯TF tracking the investments of💝 Congressional Democrats launched in 2023 with the ticker "NANC," a nod to Pelosi's reputation.

Pelosi's disclosure on Tuesday revealed she also bought call options for Vistra (VST), shares of which soared 8% Tuesday, as well as cybersecurity firm Palo Alto Networks (PANW), which advanced more than 3%. Pelosi's other investments included stakes in Alphabet (GOOG)(GOOGL), Amazon (AMZN), and Nvidia (NVDA). She sold some of her stakes in Nvidia and Apple (AAPL) on the last day of 2024.
