Top 10 AI Stocks to Watch in September

This week, we break down the AI stock market outlook for September — drawing on insights from MarketBeat, The Motley Fool, Zacks, Yahoo Finance, and Trader — and aligning them with our proprietary AIIP model.

The prevailing sentiment for AI stocks in September is bullish, driven by the expanding application of AI beyond core infrastructure, robust corporate earnings, and widespread positive analyst revisions.

Below we highlight the top AI stock selections identified by Marketbeat, The Motley Fool, Zacks, Yahoo Finance, and Trader, alongside our independent assessment and ranking based on the AIIP model — our proprietary AI Investing Pulse (AIIP) Scores*, which evaluates stocks on growth potential, momentum, and relative market performance. Here are the top picks.

Snowflake (SNOW)

What the Company Does
Snowflake operates a data lake platform central to AI analytics and training.

Why It Stands Out
Its recent “blowout” quarter sparked a stock price surge and over 30 analyst upgrades. While momentum is strong, the valuation looks stretched after a steep rally.

📊 AIIP Scores: Total Score 66, RS 88 → Momentum List

MongoDB (MDB)

What the Company Does
MongoDB provides a leading database platform widely used for AI applications.

Why It Stands Out
Q2 revenue doubled YoY with accelerating growth and strong guidance. However, its rapid 45% spike in five days and wide analyst target range ($170–$430) highlight volatility.

📊 AIIP Scores: Total Score 81, RS 44 → Fundamental List

Nvidia (NVDA)

What the Company Does
Nvidia is the market leader in GPUs, CUDA, and AI-specific compute hardware.

Why It Stands Out
Q1 revenue hit $44.1B (+69% YoY), cementing its leadership. Risks include China export restrictions ($4.5B write-down) and geopolitical tensions.

📊 AIIP Scores: Total Score 100, RS 75 → Fundamental List

Microsoft (MSFT)

What the Company Does
Microsoft integrates AI across its Office suite and Azure cloud services.

Why It Stands Out
Azure grew 33% (AI contributed 12 points). Strong adoption of Copilot supports long-term growth, though cloud spending could soften in a slowdown.

📊 AIIP Scores: Total Score 81, RS 61 → Fundamental List

Alphabet (GOOGL)

What the Company Does
Alphabet powers AI through Google Search, Google Cloud, and new AI-driven initiatives like health tools.

Why It Stands Out
Trading at a P/E of 16.9 (below its 5-year average), Alphabet remains a “clear AI bargain.” Regulatory pressures and cloud budget risks are the main headwinds.

📊 AIIP Scores: Total Score 94, RS 67 → Fundamental List

Palantir Technologies (PLTR)

What the Company Does
Palantir develops AI-powered platforms (Gotham, Foundry) for governments and enterprises.

Why It Stands Out
Its exceptional growth and market dominance have driven a meteoric rise, though valuations look stretched. Still, it combines strong fundamentals with unmatched momentum.

📊 AIIP Scores: Total Score 93, RS 99 → Watchlist

Duolingo (DUOL)

What the Company Does
Duolingo offers AI-enhanced language learning and is expanding into broader education.

Why It Stands Out
Analysts see upside, but competition from emerging AI language tools (e.g., ChatGPT) and its P/E of 132 create downside risk.

📊 AIIP Scores: Total Score 93, RS 68 → Fundamental List

Amazon (AMZN)

What the Company Does
Amazon leverages AI through AWS cloud compute and automation across logistics.

Why It Stands Out
With 1M robots in warehouses and Q2 operating profits up 31%, AI is boosting efficiency. Heavy infrastructure spending could weigh on margins if demand dips.

📊 AIIP Scores: Total Score 90, RS 64 → Fundamental List

Arista Networks (ANET)

What the Company Does
Arista provides high-performance networking solutions critical to cloud and AI data centres.

Why It Stands Out
EPS revisions show accelerating growth (+23.79% YoY). Strong fundamentals but RS is just below Watchlist level.

📊 AIIP Scores: Total Score 96, RS 78 → Fundamental List

Micron Technology (MU)

What the Company Does
Micron supplies AI-driven memory and storage solutions (HBM, DRAM).

Why It Stands Out
Demand recovery, long-term contracts, and solid finances position it well. No major risks highlighted in the current outlook.

📊 AIIP Scores: Total Score 86, RS 66 → Fundamental List

Final Take

Based on our AIIP model, Palantir Technologies (PLTR) is the sole stock earning Watchlist status this September, combining strong fundamentals with outstanding momentum.

Nvidia (NVDA) and Arista Networks (ANET) are standout names on the Fundamental List, close to Watchlist thresholds. Snowflake (SNOW), while on the Momentum List, remains one to watch given strong public sentiment and a pivotal role in AI infrastructure.

Other names — including MongoDB, GitLab, Duolingo, Amazon, Microsoft, Alphabet, and Micron — remain on the Fundamental List, with excellent business strength but requiring greater momentum to break out.
