Been looking at some straightforward ways to get AI exposure without picking individual stocks, and honestly, the infrastructure angle is where it gets interesting.

So NVIDIA's crushing it, everyone knows that. But here's what I'm noticing - the real money might be flowing into the stuff that actually powers AI, not just the chip makers. We're talking energy, data centers, the whole backbone. That's where Tortoise Capital's TCAI comes in, which is kind of a left-field move for them since they're energy-focused normally. But it makes sense when you think about it. The fund holds around 50 companies across three buckets: power generation, data center operators, and infrastructure tech. Constellation Energy is in there, Vertiv too. TCAI's up something like 27% from when it launched in August 2025, and the expense ratio sits at 0.65%, which is pretty reasonable for an actively managed fund. Downside is it's still small - under $80M in assets - so volume isn't huge.

If you want a straightforward alternative with more liquidity, AIPO from Defiance is worth comparing. Launched around the same time, but it's tracking an index rather than being actively managed. You get roughly 60 holdings across AI hardware, data centers, and utilities. More diversified in some ways, though it's actually pretty concentrated - four names make up about a third of the fund. AIPO's hit $250M in AUM and trades way more actively. Returns are solid too, north of 21% for 2025, and the expense ratio is basically the same at 0.69%.

Now if you want to think differently about AI, there's KOID - the humanoid robotics play. This is straightforward in its focus but broader in scope. We're talking humanoid robots, embodied intelligence, the whole next frontier. Morgan Stanley's throwing around projections of $5 trillion in annual revenue by 2050 for this space. KOID holds companies across semiconductors, robotics, sensing hardware, all of it. It's not pure AI, but it's deeply connected. Returns hit 15% last year, expense ratio matches AIPO at 0.69%, and it even pays a small dividend.

The straightforward takeaway? If you don't want to chase individual AI names but still want exposure, these three ETFs cover different angles of the same trend. Infrastructure angle with TCAI or AIPO if you want that play, or robotics with KOID if you're thinking longer term. Each has its own risk profile and liquidity situation, so depends what you're actually looking for in a portfolio.
