Top AI stocks today: August 17, 2026

ACM Research surges 6.49pct on AI semiconductor equipment momentum

ACM Research Inc. (NASDAQ: ACMR) posted the day's biggest gain among the top AI stocks, climbing 6.49pct to $85.64 on heavy volume. The semiconductor equipment maker, which supplies wafer-cleaning and surface-preparation tools primarily to leading fabs in mainland China, reported strong Q2 2026 earnings that beat analyst expectations and lifted full-year guidance. According to data compiled by S&P Global, the analyst consensus target for ACMR sits at $115.14 - implying 34.5pct upside from Monday's close - on a "Buy" consensus from eight covering analysts. StartupHub.ai data shows 65 AI chip and semiconductor startups currently tracked on our platform, a cohort whose private-market momentum is now confirmed in public-market performance as advanced fab spending accelerates across Asia. ACMR is up 90.82pct year-to-date, reflecting the market's conviction that chip equipment spending is a structural, not cyclical, AI infrastructure story.

Teradyne rises 5.81pct as AI chip testing demand remains strong

Teradyne Inc. (NASDAQ: TER) extended its post-earnings rally, adding 5.81pct to close at $443.14 - a one-month gain of 32.77pct that makes it one of the best AI chip stocks to buy in 2026. The test and automation equipment maker reported record Q2 2026 results on July 29, with revenue more than doubling year over year and earnings per share growing over 300pct, driven by AI chip testing demand across all product segments. Goldman Sachs maintains a Buy rating with a $465 price target, and JPMorgan analyst Joseph Cardoso raised his target to $465 from $450 with an Overweight rating following the print. The next earnings report is October 27. Teradyne is the critical quality-gate for every advanced AI chip that leaves a fab, and as GPU complexity rises, so does the testing time per unit - a virtuous cycle for TER's revenue model.

Applied Materials gains 5.55pct on record Q3 revenue of $9.12 billion

Applied Materials Inc. (NASDAQ: AMAT) anchored the chip equipment surge Monday, rising 5.55pct to $535.31 after reporting record fiscal Q3 2026 revenue of $9.12 billion. The company guided Q4 revenue in the $9.75 billion to $10.75 billion range, signaling that AI-driven fab investment is accelerating rather than plateauing. Seaport Research analyst Jay Goldberg raised his price target on AMAT to $575 from $500 with a Buy rating following the print; UBS maintained its Buy rating at a $675 target. Among 38 analysts covering the stock, the consensus rating is "Strong Buy." AMAT is up 99.10pct year-to-date and sits at the centre of the best AI infrastructure stocks of 2026. Unlike hyperscalers whose AI returns remain debated, AMAT's revenue growth is direct and verifiable: every advanced node that goes into production requires its equipment.

Micron crosses $1,000 as memory demand tracks AI training buildout

Micron Technology Inc. (NASDAQ: MU) crossed the $1,000 per-share mark Monday, climbing 4.13pct to $1,011.75. Up 220.76pct year-to-date, MU is the standout performer among the top AI stocks 2026 universe. The thesis is structural: every large language model run requires high-bandwidth memory, and Micron is one of only three global HBM suppliers. Its five-day gain of 16.49pct and one-month gain of 16.90pct suggest the market is pricing in a supply-demand inflection as AI training clusters at Microsoft, Google and Amazon pull forward memory orders. For investors looking at best AI stocks to buy with direct hardware exposure and no software-execution risk, MU remains the clearest single-ticker expression of the AI infrastructure buildout.

Notable but quieter

ServiceNow Inc. (NYSE: NOW) dropped 5.08pct to $117.70, the sharpest SaaS decline of the session, as investors rotated ahead of a heavy enterprise software earnings week. monday.com Ltd. (NASDAQ: MNDY) fell 4.79pct to $83.33, now down 41.90pct year-to-date, the deepest drawdown among the SaaS names in this universe. MongoDB Inc. (NASDAQ: MDB) gave up 4.70pct to $438.70 despite a one-month gain of 35.67pct. Meta Platforms Inc. (NASDAQ: META) shed 3.54pct to $568.97, its fifth losing session in eight, as the market weighs heavy AI capex against uncertain near-term monetization. Microsoft Corp. (NASDAQ: MSFT) slid 3.04pct to $480.35, extending its recent softness despite last month's Azure blowout. On the positive side, Lam Research Corp. (NASDAQ: LRCX) added 3.45pct to $343.84, ASML Holding N.V. (NASDAQ: ASML) gained 2.12pct to $1,883.12, and Taiwan Semiconductor Manufacturing Co. (NYSE: TSM) rose 1.08pct to $430.97 - a clean sweep for the chip equipment and foundry sub-group against a weak market. CoreWeave Inc. (NASDAQ: CRWV) rose 0.70pct to $106.00 and is now up 45.09pct over the past month as AI infrastructure demand continues to support its hyperscale colocation model.

What are the top AI stocks to buy in August 2026?

Across hardware, hyperscale cloud, and enterprise SaaS, the consensus top AI stocks in August 2026 include Applied Materials (AMAT), Teradyne (TER), and Micron Technology (MU) on the hardware side; NVIDIA Corp. (NASDAQ: NVDA) and Taiwan Semiconductor Manufacturing Co. for AI chip supply; and Palantir Technologies Inc. (NYSE: PLTR) for enterprise AI software. Wall Street's 2026 focus has shifted from training-cluster buildout to inference efficiency and AI-agent monetization, which reshuffles which names lead on any given session. Monday's tape was a reminder that the equipment layer often outperforms most sharply when earnings beats arrive - and with top AI stocks 2026 still skewed toward hardware names by YTD performance, that rotation dynamic is likely to persist through NVIDIA's August 26 print.

Core watchlist

Chips

Nvidia (NVDA): -0.07pct on heavy volume (81M shares). Quiet ahead of the August 26 earnings print; consensus $28.7B revenue is the line in the sand - any guidance commentary on Blackwell Ultra supply timing moves the tape.
AMD (AMD): -1.63pct on average volume. AI GPU ramp continues but NVDA's Blackwell supply advantage keeps AMD in the shadow; next catalyst is MI400 sampling commentary or any hyperscaler co-development announcement.
Broadcom (AVGO): -0.14pct on average volume. Custom ASIC AI chip pipeline is the thesis; XPU revenue timeline is what the market is waiting on for the next re-rating.
Taiwan Semiconductor (TSM): +1.08pct on average volume. Swept along by the chip equipment rally; CoWoS advanced packaging capacity remains the single biggest AI chip supply bottleneck to watch.

Hyperscalers

Microsoft (MSFT): -3.04pct on heavy volume. AI capex concerns weigh again; the Azure +43pct Q4 blowout has been digested and investors now want evidence of margin accretion from AI workloads.
Alphabet (GOOGL): -0.55pct on average volume. Steady; Google Cloud AI workloads are the carrier, but last month's $205B capex announcement still hanging over sentiment.
Meta Platforms (META): -3.54pct on heavy volume. Down 12.52pct YTD; capex commitment to AI is a thesis risk until top-line AI monetization shows in the revenue line - fifth losing session in eight.
Amazon (AMZN): -0.51pct on average volume. AWS AI inference demand is the bull case; WMT and TGT earnings this week are the consumer health proxy that shapes macro sentiment.

Enterprise SaaS

Oracle (ORCL): -2.57pct on above-average volume. Down 25.07pct YTD despite AI infrastructure cloud tailwinds; Japan sovereign cloud win is the lone near-term catalyst keeping the story together.
Salesforce (CRM): -2.67pct on above-average volume. Agentforce monetization is the entire thesis; earnings due this week and guidance on agent ARR is the make-or-break number.
ServiceNow (NOW): -5.08pct on above-average volume. Pre-earnings SaaS rotation the likely culprit; workflow-AI agent rollout still the multi-quarter carrier narrative.
monday.com (MNDY): -4.79pct on average volume. mondayAI suite expansion is the 2026 story but the market has not waited; down 41.90pct YTD is the sharpest drawdown in this universe.

Vol / retail

Palantir (PLTR): -0.86pct on average volume. Up only 2.79pct YTD after a volatile year; AIP enterprise contract pipeline is the forward catalyst, watching for DoD renewal and any Fortune 500 AIP expansions.
Tesla (TSLA): -0.87pct on average volume. Down 22.55pct YTD; FSD v14 timeline and Optimus production ramp are the two variables that determine whether TSLA gets re-rated as a Magnificent 7 AI stocks play into year-end.
Snowflake (SNOW): +0.36pct on light volume. Flat on the day; Cortex AI agent consumption revenue is the 2026 growth lever, and management tone on the next print will be watched closely.

What to watch tomorrow

The heaviest AI-relevant catalyst this week: Salesforce (CRM), CrowdStrike Holdings Inc. (NASDAQ: CRWD), and Palo Alto Networks (PANW) all report earnings before Friday - a genuine referendum on whether AI software monetization is keeping pace with AI hardware demand. Both CRM and PANW are down on the year, so guidance tone matters as much as the headline number. The Federal Reserve releases FOMC minutes Wednesday, August 19 at 2pm ET, potentially clarifying the September rate picture after Goldman Sachs said Monday a September hike is "very unlikely." Baidu Inc. (NASDAQ: BIDU) reports this week, providing a window into the China AI market. Walmart earnings Thursday add a consumer macro read. The NVIDIA Corp. earnings date of August 26 after the close remains the single biggest near-term catalyst for the entire AI stocks universe, with consensus revenue at $28.7 billion.
