Just caught something interesting about the AI chip space that's worth paying attention to. TSMC dropped some seriously bullish guidance recently, and it's reshaping how I'm thinking about the whole semiconductor and AI infrastructure play for the rest of 2026.

Look, the fundamentals are lining up in a way we haven't seen in a while. Inflation's cooling, the Fed's likely cutting rates again this year, and here's the kicker - the entire S&P 500 is expected to grow earnings by 12.8% in 2026. But the Tech sector? That's running 20% earnings growth. All 16 market sectors are projected to post positive earnings for the first time since 2018. That's the kind of tailwind that doesn't come around often.

TSMC just raised its capex guidance to between 52 and 56 billion dollars, up significantly from 40.9 billion last year. They're expecting 30% revenue growth in 2026 alone, with a 25% compound annual growth rate through 2029. When the foundry that makes chips for Nvidia and Apple is throwing that kind of money at expansion, it tells you everything you need to know about where the industry sees demand heading.

So which plays should actually be on your radar right now? I've been looking at two that feel particularly interesting.

First up is Vertiv. This is the infrastructure play everyone sleeps on. While everyone's focused on the chip designers, Vertiv is solving the behind-the-scenes problems that actually make AI data centers work - power, cooling, all that unglamorous stuff that nobody talks about but everything depends on. They work directly with Nvidia on these solutions, which is a pretty solid endorsement.

Here's what's wild about VRT - it's up over 1000% in three years, but it's down 12% from October highs even as other AI stocks are hitting fresh peaks. The company's projecting 28% revenue growth in 2025 and 22% in 2026, reaching 12.43 billion. That's more than doubling sales between 2022 and 2026. On the earnings side, adjusted EPS is expected to grow 45% this year and 29% next year. The stock's trading at a 25% discount to its recent highs at 32.5X forward earnings. They report Q4 results on February 11, and honestly, this pullback mixed with that growth outlook feels like a setup.

Then there's AMD. Look, everyone knows Nvidia dominates the AI chip market, but being second in that race is hardly a bad position when you're looking at multi-year growth. AMD's been expanding its AI-optimized portfolio across CPUs, GPUs, networking, and software. They've outlined plans for over 35% revenue compound annual growth rate in data center and AI over the next three to five years, with targeting greater than 20 dollars non-GAAP EPS.

The numbers here are genuinely impressive. AMD grew from 6.7 billion in revenue back in 2019 to 25.8 billion in 2024. They're projecting 32% growth in 2025 and 28% in 2026, which would put them at 43.43 billion. EPS growth is expected at 20% this year and 58% next year, reaching 6.26 per share. Over the next several years, earnings are projected to climb well above 12 per share. The stock's up 97% over the past 12 months and roughly 11,400% over the past decade, yet it's still trading at a 50% discount to five-year highs at 40X forward earnings. AMD reports Q4 results on February 3.

Here's my take - we're in a phase where the best AI stocks to buy are the ones with real earnings growth backing them up, not just hype. The infrastructure plays and the chip designers that can actually execute on capacity expansion are going to be the real winners. Both VRT and AMD fit that profile, and the technicals suggest both are setting up for moves higher. Worth keeping close tabs on these heading into earnings season.
