Two AI infrastructure stocks positioned to benefit from continued capital spending: ACM Research signaling 20-30% growth in 2026, and Ouster expanding lidar technology beyond autonomous vehicles.

ACM Research has shifted from wafer cleaning to higher-value semiconductor deposition, competing with Applied Materials and Lam Research. The company is signaling a 2026 growth rate of 20-30%.

Ouster supplies lidar sensors (optical scanning technology) used in autonomous vehicles, robotics, and industrial equipment. The company's L3 chip offers increased range, resolution, and lower power consumption compared to prior generations, and Ouster also provides software products (Ouster Gemini and Blue City) that generate recurring revenue.

Hyperscalers continue raising capital expenditure: Meta raised 2026 capex estimates to $145, and SpaceX is expected to pour over $100b into a new Terafab. These commitments are expected to create supply bottlenecks that benefit semiconductor and sensor suppliers.
