You ever notice how the letter "I" seems to own the backbone of the modern world? Seriously. From the silicon inside your phone to the software filing your taxes, it's everywhere. We aren't just talking about a few random startups. We're looking at the massive, global giants that basically keep the lights on and the data flowing.
Take IBM. A few years ago, people were ready to write them off as a "legacy" relic. Boring. Old. Dusty. But skip to early 2026, and they are suddenly the cool kids again. They stopped trying to out-Amazon Amazon and instead went all-in on "Enterprise AI" and hybrid cloud. It worked. By mid-January 2026, their market cap hit roughly $283 billion. They found a niche helping big banks and hospitals manage "Agentic AI"—the kind of tech that doesn't just chat with you but actually finishes your paperwork.
Why Companies That Start With I Still Dominate the Market
There is something specific about this group. It’s not just a coincidence. Many companies that start with i are rooted in the "infrastructure" of life. Intel makes the chips. Intuit handles the money. Iberdrola powers the grid. They are the plumbing of the 21st century.
Honestly, the sheer scale is hard to wrap your head around. If you look at the stock market right now, these names aren't just tickers; they are geopolitical chess pieces.
The Intel Renaissance
Speaking of chess pieces, let’s talk about Intel. If you follow the news, you know they had a rough patch. Like, a really rough patch. They lost their manufacturing lead to Taiwan's TSMC and watched AMD eat their lunch in the server market.
But 2026 is looking like the year of the "Silicon Renaissance."
Under new leadership (Lip-Bu Tan took over as CEO in March 2025), they’ve pivoted hard. They aren't just designing chips anymore; they are trying to be the world’s foundry. They’ve got these massive "High-NA EUV" machines—basically the most expensive and complex printers on Earth—to make the next generation of 1.4nm chips.
- The Big Win: Nvidia actually invested $5 billion into Intel recently just to secure packaging capacity.
- The AI PC: Intel estimates that 60% of new laptops by the end of 2026 will be "AI-capable," and they’re the ones making the brains for them.
It’s a high-stakes gamble. If they mess up the yields on their new 18A process node, it’s game over. But if they nail it? They become the "National Champion" for U.S. manufacturing.
Intuit and the "System of Intelligence"
Then you have Intuit. You probably know them from the yearly headache of TurboTax or the "cha-ching" sound of QuickBooks. While other companies were just talking about AI, Intuit actually integrated it into the workflow of millions of small businesses.
Their numbers for the first quarter of fiscal 2026 were kind of insane. Revenue hit $3.9 billion, up 18%.
Why does this matter to you? Because they are moving toward what they call a "system of intelligence." Basically, they want your accounting software to tell you that you’re about to run out of cash before it happens, not after. They even have a partnership with OpenAI to make Credit Karma smarter at finding you loans you actually qualify for.
Illumina and the Billion Cell Atlas
In the world of health, Illumina is the name you can't ignore. They just announced something called the "Billion Cell Atlas" in January 2026.
It’s exactly what it sounds like. A massive map of human disease biology designed to help drug companies find cures faster using AI. Clinical sequencing now makes up about 60% of their revenue. People are moving from basic genetic tests to "whole genome sequencing," which is a fancy way of saying they are looking at every single "letter" in your DNA, not just the highlights.
The Global "I" Powerhouse: Infosys and Iberdrola
It's not all U.S.-based, either.
Infosys is the giant out of India that basically runs the IT departments for half the Fortune 500. Their ADR stock price recently jumped over 10% after they bumped up their revenue guidance for 2026. They are hiring thousands of people while other tech firms are still leaning into layoffs. It shows you where the demand is: companies are desperate for help implementing all this new AI stuff.
And then there's Iberdrola.

They are a Spanish utility company, but that’s like calling a Ferrari "a car." They are arguably the world leader in offshore wind. They’ve pledged to invest €41 billion through 2026 to accelerate "electrification."
Think about that. While everyone else is arguing about energy, they are building the massive wind farms in the UK, U.S., and France that will actually charge your future Tesla. They even signed a deal with Microsoft to provide 150MW of renewable energy specifically to power AI data centers. It’s all connected.
What Most People Get Wrong About These Giants
People think these massive firms are too big to move. That's the trap.
In reality, companies that start with i are often the ones doing the most radical pivots. IBM ditched its legacy managed infrastructure business (Kyndryl) to focus on software. Intel is splitting its manufacturing and design units. These aren't just businesses; they are ecosystems.

If you're looking at this from a business or investment perspective, keep these three things in mind:
- Look for the "Foundry" Play: Whether it's Intel making the chips or Infosys providing the labor, the companies enabling the AI boom are often safer bets than the ones just using it.
- Infrastructure is King: Software is great, but you need power (Iberdrola) and hardware (Intel) to run it. The physical world still matters.
- Data Sovereignty: Governments are getting picky about where their data and chips are made. Companies like Intel and IBM are leaning into this "Sovereign AI" trend by building local capacity.
Keep an eye on the upcoming earnings calls late this month. IBM reports on January 28, and it’ll be the first real look at whether that $9.5 billion AI backlog is turning into real, cold cash. The "I" companies aren't just part of the market anymore—they are the market.
To get ahead of the next shift, you should dive into the specific quarterly filings for Intel's 18A progress or monitor Iberdrola's upcoming offshore wind auctions in the North Sea. These are the real-world metrics that will dictate the next decade of growth.
