Teradyne had a big Wednesday. The stock closed at $358.29, up nearly 12%, landing it at the top of the S&P 500 leaderboard and a brand new all-time high. It’s a striking move for a stock that’s already up 85% year-to-date.

Teradyne, Inc., TER

The catalyst? Intel’s reported entry into the Terafab project — an advanced manufacturing initiative linked to Elon Musk that also counts SpaceX, xAI, and Tesla as participants. Intel is one of Teradyne’s major customers, sitting alongside Samsung, Qualcomm, Texas Instruments, and IBM. So news of Intel deepening its footprint in advanced chip manufacturing lands a little differently for TER than it might for others.

The broader market got a lift too. News of a U.S.–Iran ceasefire pushed investors back into tech and growth names, giving TER an extra tailwind on the day.

Teradyne also launched two new platforms recently. The Photon 100 targets silicon photonics and co-packaged optics manufacturing. Omnyx is aimed at printed circuit board assemblies for AI and data center applications. Both slot neatly into the company’s pivot toward AI-driven demand.

That pivot is hard to miss in the numbers. AI now makes up more than 60% of Teradyne’s total revenues. The company expects that figure to cross 70% in early 2026.

Analyst Price Targets

Baird’s Quinn Fredrickson raised his price target to $332 from $305, keeping a Buy rating. He pointed to limited Middle East risk exposure and improving cyclical trends heading into 2026 and 2027.

Morgan Stanley’s Shane Brett lifted his target to $306 from $288, maintaining a Hold. Brett forecasts Teradyne’s networking revenue to more than double in 2026 — a meaningful upgrade to his prior estimates.

Cantor Fitzgerald went further, raising its target to $330 and flagging the shift in business mix toward AI as a key driver.

What the Market Is Saying

Despite the enthusiasm, Wall Street’s average price target of $313.20 implies about 12.6% downside from Wednesday’s close. The overall rating across 12 Buys and 5 Holds lands at Moderate Buy — positive, but measured given the run the stock has already had.

TER’s market cap now sits at roughly $53.96 billion, with a P/E ratio of 90.67. InvestingPro flagged the stock as potentially overvalued relative to its Fair Value estimate.

Aletheia Research noted a rebound in Taiwan’s tester imports, which could benefit Teradyne through increased orders from key players like KYEC.

The stock’s 1-year gain stands at 373%, per InvestingPro data. Wednesday’s close at $358.29 is the highest the stock has ever traded.
