As seen on the 24/7 Wall St. homepage on September 17, 2026.
Tempus AI closed 14.46% higher, the biggest move in a 111-name priority list where four other gainers ran 9% or better. The downside was far tamer: DraftKings led decliners at 7.38%, and nothing else lost more than 6.4%.

Tempus AI finished the September 17 session at $80.08, up 14.46%, making it the standout mover across a 111-name priority watchlist. That kind of single-day move commands attention regardless of what drove it, because it signals unusually concentrated buying pressure in a name that already carries significant institutional interest.
The strength was not isolated: four other names on the same list, including NuScale Power, IonQ, Super Micro Computer, and Astera Labs, gained 9% or better by the close. The breadth of the move across AI infrastructure, nuclear power, and quantum computing names suggests a broad risk-on rotation into high-growth technology themes.

The selling pressure was comparatively mild, with DraftKings the hardest-hit decliner on the list, dropping 7.38% to $22.54, and fuboTV, CoreWeave, Spotify, and Axon Enterprise also lower. The asymmetry between the top gainers and top losers points to a session where buyers were clearly in control.
For investors tracking these names, the clustering of gains across AI and adjacent sectors is worth monitoring in the sessions ahead. When multiple high-beta technology names move together this sharply in a single afternoon, the follow-through, or lack of it, in the next one to two days often reveals whether the move reflected durable demand or a short-term squeeze.
