Jim Cramer, CNBC’s market commentator, has identified companies and sectors that are likely to benefit from the wave of artificial intelligence (AI).

What Happened: Cramer believes AI will be crucial to significant market rallies in the coming years. “This technological revolution is crossing all barriers, even potentially becoming the heart of our national security apparatus,” Cramer said. He suggested that AI could be the key to substantial financial gains over the next half-decade, CNBC reported on Wednesday.

Companies like NVIDIA Corp (NASDAQ:NVDA), which produces graphics chips vital for generative AI, have seen significant growth recently. Cramer highlighted that the computing power required for AI-enabled machines is at the core of the current re-industrial revolution and will boost stocks from various sectors.

According to Cramer, the construction required for new data centers is one reason why stocks like Caterpillar Inc. (NYSE:CAT) are performing well. Power management company Eaton Corporation PLC (NYSE:ETN) and Vertiv Holdings Co (NYSE:VRT), which manages wiring in data centers, are also seeing gains due to increased demand.

Cramer also identified companies like Salesforce Inc (NYSE:CRM) and ServiceNow Inc (NYSE:NOW), which manage and parse data, as potential beneficiaries of the AI wave. He also pointed out the importance of sustainable power generation utilities like Constellation Energy Corp (NASDAQ:CEG) and natural gas companies like Enbridge Inc (NYSE:ENB) in this new tech era.

“The AI revolution is already producing some of the most investible themes of all time,” Cramer concluded.

Why It Matters: Cramer’s forecast comes as AI stocks have been experiencing a boom, with companies like Super Micro Computer joining the S&P 500 Index.

However, Cramer has also expressed caution about certain AI stocks, such as Super Micro Computer Inc (NASDAQ:SMCI), which he believes has “gotten too hot”.

He earlier suggested alternative AI investments such as Dell Technologies Inc (NYSE:DELL), Advanced Micro Devices, Inc. (NASDAQ:AMD), and Cadence Design Systems Inc (NASDAQ:CDNS).

Meanwhile, Harvard economist Ken Rogoff has warned of a potential AI stock bubble, citing the expectation of AI remaining unregulated as a potential risk.
