Artificial intelligence (AI) could be one of the biggest investment themes of the next decade.
But investors do not have to find the next Nvidia or pick which software company will ultimately come out on top.
ASX exchange traded funds (ETFs) can provide a simpler way to gain exposure to the theme.
Here are three very different options. Investors could choose the one that best suits their portfolio, or potentially own more than one.

Betashares Nasdaq 100 ETF (ASX: NDQ)
The Betashares Nasdaq 100 ETF could be a good option for investors who want AI exposure without making it the entire investment case.
The fund tracks 100 of the largest non-financial companies listed on the Nasdaq exchange.
That includes businesses involved in semiconductors, cloud computing, software, digital advertising, ecommerce, and consumer technology.
Many of these companies are investing heavily in AI or are providing the infrastructure needed to support it. This includes Microsoft (NASDAQ: MSFT), Nvidia (NASDAQ: NVDA), and Google parent Alphabet (NASDAQ: GOOG).
Overall, this gives investors exposure to the theme while still owning a wider collection of leading growth companies.
Betashares Global Robotics and Artificial Intelligence ETF (ASX: RBTZ)
Another option is the Betashares Global Robotics and Artificial Intelligence ETF.
This fund gives investors exposure to companies involved in robotics, automation, artificial intelligence, drones, autonomous systems, and related technologies.
I think this is an interesting way to approach AI because it looks beyond chatbots and software.
AI can also help machines perform more complicated tasks in factories, warehouses, hospitals, farms, and logistics networks.
Businesses around the world are constantly looking for ways to lift productivity and automate repetitive work.
If that continues, robotics and intelligent machines could become far more common over the next decade.
Global X Artificial Intelligence ETF (ASX: GXAI)
For investors wanting more direct exposure to the AI theme, the Global X Artificial Intelligence ETF could be worth considering.
This fund invests across different parts of the AI ecosystem.
That can include companies involved in semiconductors, software, cloud computing, data infrastructure, automation, and other technologies needed to develop and deploy artificial intelligence.
The good thing here is that nobody really knows where all the winners will come from.
Some winners could build AI models. Others could supply the chips, computing power, software tools, or infrastructure required to run them.
The Global X Artificial Intelligence ETF gives investors a way to back that wider opportunity rather than trying to identify one company that will dominate the AI era.
