What Happens To Synopsys Stock If AI Learns To Design Chips Without It?

Synopsys (SNPS) sells the electronic design automation software and design IP that chipmakers use to build new chips. Its stock has lost 16.3% over the past year, while the S&P 500 gained 18.5%. A Needham analyst said on the fiscal Q3 2026 earnings call that the question investors keep asking is whether AI could learn to design chips without those tools. The biggest risk is not a sudden break. It is that Ansys revenue could hide the threat inside the headline totals while it builds.

Synopsys Says AI Will Need More Of Its Software

The bear case, as that analyst framed it, is AI-native chip design that bypasses all the commercial EDA tools, using models trained on data those same tools generate. If that worked, chipmakers would need fewer of the licenses Synopsys sells.

Management rejects the premise. The CEO argues that customers will not spend hundreds of millions of dollars on a chip without sign-off tools they trust. By the CEO’s account, AI agents that take on more engineering work call its tools at a much higher rate, and its agentic AI platform has more than 30 active customer engagements.

The latest quarter does not contradict management so far. Revenue rose about 42% to $2.477 billion in fiscal Q3 2026, above the top of guidance, and management raised its full-year outlook.

But Synopsys’s Core Business Is Growing Far Slower Than Its Total

Much of that 42% is Ansys, the simulation software business Synopsys bought a year ago. Ansys added about $711 million, close to three-tenths of the quarter’s revenue. The core electronic design automation business grew 8.5% in fiscal Q3 2026.

Management calls that strong against a tough comparison, since EDA grew 16% a year earlier. It guides organic EDA growth to double digits in fiscal Q4 2026 and for the full year.

This is where the risk hides. The threat the analyst described targets EDA tools, while Ansys revenue sits on top of them in every total. Ansys has now been inside Synopsys for a full year, so it will add less to year-over-year growth from here.

And Synopsys’s Newest Growth Bets Are Still Early

Multiphysics Fusion, the first joint Synopsys and Ansys product, builds thermal analysis into the chip design flow, and customers including NVIDIA and Cisco have validated it. Management expects it to start adding to EDA growth only in 2027.

Pricing is still being worked out too. Management is defining how to charge for agents, by subscription or by how much software they consume, and promises more on September 30. In design IP, Synopsys is in advanced discussions with customers including hyperscalers on Factory 2, a plan to add royalties on custom silicon.

So the threat is possible but slow, and nothing in the reported numbers confirms it yet. The figure to watch is organic EDA growth in fiscal Q4 2026: a miss on the double-digit guide would be the first hard sign.

Until then, the stock trades at about 75% of its 52-week high. If that looks like an opening rather than a warning, our dip-buying screen lines up other stocks trading well off their highs.

So How Much Synopsys Can You Hold While AI Plays Out?

It depends on what else you own, since a threat this slow will not announce itself on the day you check. Weighing that across everything you hold is what our rule-based High Quality Portfolio does. The Trefis High Quality (HQ) Portfolio has a track record of outpacing the three major indices.
