Have you ever watched a market theme catch fire so fast that it felt like the whole world was betting on the same wild idea? I remember scrolling through headlines a couple of years back thinking, “This can’t possibly get more ridiculous.” Yet here we are again in 2026, staring at something eerily similar. The frenzy around those game-changing weight-loss medications taught investors some harsh but valuable lessons—and now artificial intelligence is running the same playbook, just with higher stakes and bigger valuations.

It started innocently enough. A breakthrough class of drugs promised to tackle obesity on a massive scale, and suddenly every corner of the economy seemed poised to feel the ripple effects. People started spinning tales about how everyday industries would transform overnight. In hindsight, a lot of that excitement was pure fantasy. The real story turned out much narrower. And if history is any guide, we’re seeing the exact same pattern unfold with AI right now.

When Hype Outruns Reality: A Familiar Market Pattern

Markets love a good narrative. They love it so much that sometimes the story grows legs of its own, sprinting far ahead of actual fundamentals. That’s exactly what happened when those GLP-1 medications exploded onto the scene. Everyone had an opinion on who would win and who would lose. The enthusiasm felt unstoppable—until the dust settled and only a handful of players emerged stronger.

Fast-forward to today, and artificial intelligence is fueling the same kind of breathless speculation. Bold claims about replacing entire workforces or rendering legacy software obsolete are everywhere. Valuations soar on the promise of total disruption. But step back for a moment. Haven’t we seen this movie before? The parallels are striking, and ignoring them could prove costly.

The GLP-1 Boom: How Wild Predictions Took Flight

Let’s rewind to that earlier wave. When the first major GLP-1 treatments hit the market, the excitement was off the charts. These weren’t just diabetes drugs anymore—they were billed as miracle solutions for weight management. Millions of people started using them, and the results were undeniably impressive. Naturally, Wall Street began connecting dots in every direction imaginable.

One particularly creative thesis suggested airlines would become surprise beneficiaries. The logic went like this: lighter passengers mean less weight on planes, which translates to meaningful fuel savings. It sounded plausible on paper. Less weight equals lower costs, right? In reality, though, the math never added up in any material way. Fuel efficiency gains were tiny compared to other variables like ticket prices or route changes. Yet for a brief moment, people actually traded on that idea.

• Analysts floated food companies as potential victims because reduced appetite could hurt snack sales.
• Some even argued processed food makers might rebound since valuations had already priced in the worst-case scenario.
• Meanwhile, the actual drug developers quietly racked up blockbuster revenues while everyone else chased shadows.

In my view, that was the first red flag. When the ancillary plays start sounding more exciting than the core story, it’s usually time to pump the brakes. The companies directly making the drugs held all the cards. Everyone else was just hoping for scraps.

Why the Side Bets Fell Flat

Here’s the thing about market manias: they thrive on extrapolation. If something works really well in one area, people assume it must reshape everything else too. With GLP-1s, the assumption was that widespread adoption would trigger massive behavioral shifts across industries. But human behavior doesn’t pivot that quickly, and supply constraints plus pricing dynamics kept the revolution more contained than expected.

Food stocks dipped on fear, then bounced when the sky didn’t fall. Airline shares barely registered any sustained lift from the supposed fuel windfall. Dividend-paying names looked tempting for a minute because they were cheap, but growth remained elusive. The lesson? Real winners concentrate power in the hands of those controlling the breakthrough itself. Peripheral players rarely capture lasting value from someone else’s innovation.

When everyone is looking for secondary effects, the primary driver usually ends up being the only one that matters.

– Market observer reflection

That insight feels almost prophetic now. Because if you swap out “GLP-1” for “generative AI,” the conversation sounds identical.

AI in 2026: Echoes of the Same Frenzy

Today, artificial intelligence dominates headlines in much the same way those weight-loss treatments did a few years ago. Breakthrough models promise to rewrite entire industries. Executives talk openly about automating jobs, replacing legacy systems, and unlocking unprecedented efficiency. The hype cycle is in full swing, and valuations reflect it.

Some leaders have been particularly vocal. One prominent figure in the space claims their technology is already writing better code than humans—and will soon make huge swaths of enterprise software redundant. It’s bold stuff. And when someone with that kind of platform speaks, markets listen. Stock prices adjust almost instantly to the narrative.

But pause and ask yourself: where have we heard this before? The pattern is repeating. Peripheral companies—those building tools that might one day be augmented or replaced—are suddenly painted as vulnerable. Meanwhile, the infrastructure powering the revolution quietly collects the lion’s share of spending.

1. Enterprise software providers face questions about obsolescence as custom AI solutions promise cheaper alternatives.
2. Cybersecurity firms get swept into the doubt, with claims that future systems will be inherently unhackable.
3. Even hardware suppliers tied to legacy architectures feel pressure as new paradigms emerge.

I’ve watched this unfold in real time, and it’s hard not to feel a sense of déjà vu. The rush to declare winners and losers often overlooks how complex these ecosystems really are. Disruption rarely happens overnight, and entrenched players usually have more staying power than the headlines suggest.

The Stocks Feeling the Heat—and Why It’s Premature

Let’s talk specifics without pointing fingers too harshly. Certain software giants have taken hits lately because analysts worry their core offerings could be replicated by nimble AI startups at a fraction of the cost. Project management tools, HR platforms, customer relationship systems—all suddenly seem “replaceable.” Valuations compress as growth expectations get questioned.

Yet many of these companies aren’t standing still. They’re integrating AI aggressively, launching agent-based features, and adapting faster than critics admit. Sure, multiples might settle lower if growth slows, but writing them off entirely feels like overkill. In my experience, the market tends to overshoot in both directions during these phases.

Security stocks face similar skepticism. The argument goes that advanced AI will make breaches impossible, so why pay premium prices for protection? It’s a seductive story—until you dig into the reality of enterprise threats. Sophisticated defenses still require layers of expertise, constant updates, and human oversight. Dismissing that seems dangerously optimistic.

Who Actually Holds the Power in the AI Ecosystem?

Here’s where the GLP-1 analogy gets really interesting. Back then, the drugmakers themselves captured the value while side stories fizzled. Today, the real beneficiaries of the AI boom appear to be the companies supplying the raw computing power, storage, and cloud infrastructure.

Think about it. Every major AI advance requires massive data centers, specialized chips, high-bandwidth connections, and enormous energy resources. The hyperscale cloud providers are positioning themselves to capture recurring revenue from this build-out. They can afford to lose a customer or two because pricing power remains strong if demand stays elevated.

The table above captures the essence. History suggests value pools toward the enablers rather than the disruptors making the loudest noise.

Challenges Ahead: Cost, Power, and Patience

Of course, none of this is guaranteed. Building the AI economy at scale comes with real hurdles. Data center construction costs must fall. Memory prices need to stabilize. Power availability can’t become a bottleneck. Shortages in any of these areas could stretch timelines and pressure margins.

Will it all resolve in the next couple of years? Hard to say. Some days I wonder if the biggest players have overestimated the pace. Other days, their confidence feels justified. They’ve got visibility into demand that most of us don’t. They understand debt servicing and capital allocation better than headlines suggest.

Perhaps the most interesting aspect is how rationality takes a backseat during these periods. People chase the narrative du jour, whether it’s lighter airplanes or autonomous code-writing agents. Emotions drive prices more than spreadsheets. That’s why stepping back and remembering past cycles matters so much.

Staying Grounded in Uncertain Times

So where does that leave investors today? I think patience remains the most underrated strategy. Avoid knee-jerk reactions to every bold prediction. Focus on companies with durable advantages, reasonable valuations after the dust settles, and clear paths to cash flow.

The GLP-1 episode showed us that revolutionary technologies don’t always revolutionize everything at once. They create concentrated winners and leave a trail of disappointed side bets. AI could follow suit—or surprise us with broader impact. Either way, the smart money stays disciplined rather than chasing headlines.

I’ve learned over the years that markets eventually reward those who see through the noise. The frenzy always feels permanent in the moment. Then one day it doesn’t. When that shift happens, the real opportunities emerge—not in the loudest stories, but in the quiet compounding of fundamentals.

And honestly? That’s what keeps this game fascinating. No matter how advanced the technology gets, human psychology stays stubbornly consistent. Greed, fear, hope—they drive prices more than any algorithm ever will. Recognizing that pattern might be the closest thing we have to a timeless edge.
