Artificial intelligence (AI) has moved beyond hype to become a transformative business technology. Major corporations now spend billions developing and deploying AI solutions across industries from healthcare to manufacturing, creating massive trillion-dollar market opportunities.

While AI stocks dominate headlines and market returns in 2024, separating hype from reality challenges even seasoned investors. Most companies remain in early-development stages, burning through capital with uncertain paths to profitability. Exchange-traded funds (ETFs) offer a safer way to participate in this emerging technology trend by spreading the risk across multiple companies.

The three ETFs discussed below offer different approaches to AI investing, from established tech giants to emerging innovators. Here's why busy investors may want to consider these funds for long-term AI exposure.

Low-cost tech leader

The Vanguard Information Technology ETF (VGT -1.56%) provides broad exposure to tech companies driving AI adoption. This passively managed ETF's minimal 0.10% expense ratio and low 15.4% turnover rate make it an efficient vehicle for long-term investors.

Semiconductors comprise 28.8% of the fund's portfolio, while software companies represent 20.2%. This balance provides exposure to both AI infrastructure builders and companies deploying the technology.

The Vanguard Information Technology ETF's top holdings include AI leaders like Nvidia, Microsoft, and Apple, along with emerging tech players like Confluent and Silicon Laboratories. Since its inception in 2004, the fund has significantly outperformed the benchmark S&P 500, thanks to the growing influence of technology -- and AI, more specifically – across the globe.
