# Robotics Stocks Punished Tuesday in AI Sell-Off: Ouster Down 10%, Aeva Technologies Down 12%, Symbotic Down 4% > Source: > Published: 2026-08-18 21:22:37+00:00 Robotics and lidar names are getting flushed in Tuesday’s trading as the broad AI trade takes a breather. **Ouster** ([NASDAQ:OUST](https://247wallst.com/companies/OUST/)) is down about 10% to $43, **Aeva Technologies** ([NASDAQ:AEVA](https://247wallst.com/companies/AEVA/)) is down about 12% to $21, and **Symbotic** ([NASDAQ:SYM](https://247wallst.com/companies/SYM/) | [SYM Price Prediction](https://247wallst.com/companies/sym/price-prediction)) is off about 4% at $41. There are no company-specific headlines behind the moves. This is rotation. ## AI Enthusiasm Cools, Duration Assets Get Hit First Three catalysts converged on the AI trade this week. Anthropic told investors over the weekend that annualized revenue reached $65 billion at the end of July, an enormous growth rate but below the $80 billion-plus figure that had been circulating in Silicon Valley. Reuters separately reported Anthropic is guiding to 2028 revenue of $190 billion to $200 billion, likely behind what investors had penciled in after commentary suggesting an exit ARR next year of $400 billion to $500 billion. On top of that, the Wall Street Journal reported that nine top tech companies now carry roughly $3 trillion of off-balance-sheet commitments tied largely to AI, growing faster than traditional capex, which totaled about $600 billion over the past year. The result is a broad risk-off day in hardware. The **iShares Semiconductor ETF** ([NASDAQ:SOXX](https://247wallst.com/companies/SOXX/)) is down about 5% intraday to $530, while the **iShares Expanded Tech-Software ETF** ([NASDAQ:IGV](https://247wallst.com/companies/IGV/)) is roughly flat at $102. Software is outperforming, memory, optics, neoclouds and consumer electronics are lower. The same power, cooling, and networking suppliers behind the data-center buildout are also caught in the tape, which is why we pulled together seven of them in a [free AI infrastructure report](https://247wallst.com/pages/ai-power-seven-offer-d905ec99.html). Compounding it, the 30-year Treasury yield hit a 19-year high today, and long-duration, pre-profit growth stories are the most sensitive assets to a rising long end. ## The Lidar Pair Ran Hard Into the Rotation Ouster and Aeva got hit hardest for a reason. Both are still unprofitable lidar plays whose valuations depend on adoption curves that stretch years out. And both have ripped into today. Ouster came in up about 30% over the past month and roughly 122% year to date. Aeva was up about 42% over the past month and roughly 79% year to date. Stocks that have doubled tend to be sold hardest when risk comes off. Both stocks delivered positive news this earnings season. Ouster’s Q2 print delivered revenue of $54.6M, up 56% year over year, with CEO Angus Pacala telling investors “customers around the world have continued to scale their investments in Physical AI.” Aeva beat top and bottom line, announced a new Optical Connectivity business for AI data centers, and disclosed a $115M follow-on that lifted liquidity to $302.9M, per its [SEC filings](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001809987&type=10-Q&dateb=&owner=include&count=40). Neither report changes the fact that these are Physical AI narratives with valuations trading on multi-year TAMs. When investors reprice long-dated growth, this is exactly the cohort that moves first. ## Symbotic Is a Different Profile Symbotic’s more modest decline reflects a fundamentally different profile. The warehouse automation company runs a real revenue business with a large contracted backlog. Its most recent quarter delivered revenue of $721M, up 22% year over year, adjusted EBITDA that more than doubled to $95M, and a contracted backlog of roughly $22.5B anchored by Walmart. The stock is down about 29% year to date and roughly 19% over the past year, which is a very different setup than a lidar name that has doubled. While Symbotic won’t see the ‘swings’ that come with companies in the path of mega-narratives like humanoid robotics, it does have an established business that makes it an attractive candidate for risk-averse investors who still want exposure to the growth of robotics. ## What to Watch Ouster’s $58 analyst target and Aeva’s $33 target both sit meaningfully above current prices, so the next test is whether sell-side sponsors reiterate through the drawdown or wait for a firmer AI capex narrative. We’ve seen wild swings in the AI space across 2026, so today could either be a one-day event or the beginning of another downtrend. *Contact [email protected] for any questions or corrections.*
