Onto Innovation (ONTO) Stock Forecast: What Could Drive It in 2026
Short answer
What is actually driving Onto Innovation (ONTO) right now is Advanced packaging and HBM: Onto's inspection and metrology tools sit in the packaging steps that assemble AI accelerators and stack high-bandwidth memory. Revenue (TTM) is ~$1.03 billion. If that keeps playing out, the setup is favourable; the risk to it is onto is a semiconductor capital-equipment company, so its revenue is cyclical and can drop sharply in a chip-spending downturn. No one can predict where ONTO trades, and Walnut does not publish targets, so treat this as a scenario, not a price target or prediction.
What could drive Onto Innovation (ONTO) higher?
1. Advanced packaging and HBM
Onto's inspection and metrology tools sit in the packaging steps that assemble AI accelerators and stack high-bandwidth memory. Management projects advanced packaging revenue to grow more than 50% in 2026, and the company disclosed a large HBM volume purchase agreement (roughly $240 million) that underpins a record backlog. This is the single biggest driver of the current growth narrative.
2. Advanced logic nodes
The newer Atlas G6 and Dragonfly G5 systems have been qualified or selected at leading logic and memory customers, including for gate-all-around metrology. Advanced-node revenue grew double digits recently and management targets roughly 25% growth for the year. Each new node transition tends to add measurement steps, which expands Onto's served market.
3. Software and recurring analytics
Beyond hardware, Onto sells factory analytics and data-management software that layers onto its installed base of tools. This piece is smaller than systems revenue but adds a stickier, higher-margin element and deepens customer relationships as fabs push for tighter process control.
What could weigh on ONTO?
Onto is a semiconductor capital-equipment company, so its revenue is cyclical and can drop sharply in a chip-spending downturn. A large share of sales concentrates in a handful of leading-edge logic and memory customers, so a single customer's capex delay or push-out can move a quarter meaningfully. Its growth thesis leans heavily on AI-driven advanced packaging and HBM demand continuing, which could soften if AI infrastructure spending cools or memory pricing weakens. Gross margin has fluctuated with product mix (it dipped year over year in early 2026 before guided recovery), and export controls on chip equipment sold into China add regulatory uncertainty. Larger, better-capitalized rivals like KLA can also pressure pricing and share.

How to think about a ONTO forecast

What could drive ONTO higher?
+
The main growth drivers are Advanced packaging and HBM; Advanced logic nodes; Software and recurring analytics. Whether they play out is the real question, not a guaranteed path.
What are the risks to ONTO?
+

A large share of sales concentrates in a handful of leading-edge logic and memory customers, so a single customer's capex delay or push-out can move a quarter meaningfully. Its growth thesis leans heavily on AI-driven advanced packaging and HBM demand continuing, which could soften if AI infrastructure spending cools or memory pricing weakens.

Larger, better-capitalized rivals like KLA can also pressure pricing and share.
