Just been thinking about where the real AI upside is hiding right now, and honestly, the best opportunities aren't where most people are looking.

See, every decade or so a transformative tech emerges that reshapes entire industries. This time it's generative AI, and we're still early enough that the leading companies in AI infrastructure and applications are trading at reasonable valuations. That's the sweet spot.

Let me break down three plays that actually make sense to me:

First up is Meta. Most people sleep on this one because of the metaverse narrative that didn't pan out, but their AI game is legitimately impressive. Ad revenue jumped 21% through the first nine months of 2025, and that's just the beginning. They're building AI agents that optimize ad campaigns for small businesses, which is going to unlock a whole new revenue stream. The real kicker? Their machine learning algorithms are getting scary good at matching ads to users. Over time, generative AI could be the unlock for engagement and creator tools. Meta's betting big too—they're talking about over $100 billion in capex for 2026. Yeah, that'll pressure near-term earnings, but the long-term picture is solid. Stock's at 22x forward earnings, which feels cheap for what they're building.

Then there's Salesforce. Their Agentforce platform is the one I'm actually most excited about. It's an AI agent system that automates tasks using your own business data. Annual recurring revenue on this thing grew 330% year-over-year in their latest quarter. Sure, it's off a small base, but the potential is massive. Management's saying customers could increase spending by 200-300% once they adopt it. They're already seeing examples of businesses doubling their spend. If Salesforce hits their 2030 targets ($60 billion revenue, 40% operating margin), this could be a home run. Trading at 19x forward earnings makes it a solid entry point for patient investors.

And then TSMC—the true backbone of the AI boom. They've got 72% market share in advanced chip manufacturing, and there's basically no one else who can produce leading-edge GPUs and AI accelerators at scale. Sales grew 35.9% in 2025 with gross margins hitting 59.9%. Management's guiding for 25% compound annual revenue growth through 2029, up from their prior 20% guidance. They're investing hard too—$52-56 billion in capex this year. When TSMC moves that aggressively on capacity, demand is locked in. Stock's at 23x forward earnings with mid-20s earnings growth expected. That's a bargain for a company with actual pricing power.

The common thread? All three are positioned as leading companies in AI with reasonable valuations and clear paths to growth. That's rare enough right now that it's worth paying attention to.
