Why Tempus AI Skyrocketed This Week
Tempus AI stock surged 39.5% this week following positive Phase 3 trial results from Merck and Moderna for a jointly developed mRNA cancer vaccine combined with Keytruda immunotherapy. The gains were driven by Tempus's pending acquisition of Personalis, which developed the genomic tumor-profiling technology central to the vaccine's development. Despite the rally, Tempus remains down roughly 10% over the past year.
