A rolling cross-category view of the lists gaining attention fastest. Positions here change far more often than anywhere else on Top 49 — that is the entire point.
Top of the category
The stories gaining ground across every category, right now
BYD · China · global EV expansion
BYD outsold Tesla in global EV deliveries for the first time in Q4 2023 and has kept widening the gap since, and the Seal — its direct Model 3 rival — now undercuts Tesla on price in most markets it has entered while matching or beating it on range. Expansion into Europe, Southeast Asia and Latin America has made it the story competitors are watching most closely this year.
MIT spinout · Devens, Massachusetts · SPARC reactor
An MIT-spun-out fusion startup betting on high-temperature superconducting magnets rather than a larger reactor to reach net-energy-positive fusion, Commonwealth Fusion Systems has attracted billions in private investment and is targeting first plasma on its SPARC demonstration reactor by the back half of this decade.
Moderna & Merck · personalised cancer vaccine, phase 3 trials
An individualised melanoma vaccine built from a patient’s own tumour mutations using the same mRNA platform behind COVID-19 vaccines, mRNA-4157 has shown a significant reduction in recurrence risk in combination with existing immunotherapy in mid-stage trials, and its progress is now the most closely watched signal for whether mRNA platforms extend meaningfully beyond infectious disease.
