You’ve probably seen the name Monsanto on everything from seed bags to protest signs. It’s a name that carries a lot of weight—and a lot of baggage. But here is the thing: if you go looking for a "Monsanto Company" headquarters today, you won’t find one.
The company is gone.

It didn't just go bankrupt or fade away. It was swallowed whole. In 2018, the German pharmaceutical and chemical giant Bayer AG bought Monsanto for roughly $63 billion. It was a massive, industry-shaking deal that effectively ended Monsanto's life as an independent entity.
Honestly, it's kinda weird how a name that big just disappears from the corporate registry, but Bayer had a very specific reason for making it happen. They didn't just buy the assets; they retired the name.
The German Giant Behind the Curtain
When we talk about who owns Monsanto Company now, we are talking about Bayer. Based in Leverkusen, Germany, Bayer is famous for inventing aspirin, but they’ve spent the last decade trying to dominate the global food supply.
By acquiring Monsanto, Bayer became the largest seed and agricultural chemical company on the planet. They didn't do it just to be nice; they wanted Monsanto’s massive portfolio of patents. We are talking about the "Roundup Ready" traits that allow crops to survive being sprayed with weedkiller, and thousands of varieties of corn, soybean, and cotton seeds.
Why the Name Vanished
Bayer wasn't stupid. They knew Monsanto was, quite frankly, one of the most hated corporate brands in history. For decades, the St. Louis-based company was the primary target for anti-GMO activists and environmentalists.
- Brand Audit: Bayer conducted global audits and found their own brand had a positive reputation, while Monsanto’s was... well, the opposite.
- The "New" Monsanto: Critics like Andrew Kimbrell from the Center for Food Safety were quick to point out that changing the name doesn't change the business. They called Bayer the "new Monsanto" almost immediately.
- Liability: Bayer hoped that by dropping the name, they could distance themselves from the mountain of lawsuits. Spoiler alert: It didn't work.
The $63 Billion Headache
Bayer’s then-CEO, Werner Baumann, pushed for this deal hard. He saw a future where Bayer controlled both the medicine you take and the food you eat. It looked great on a spreadsheet.
But in reality? It’s been a bit of a nightmare.
The ink was barely dry on the contract when the legal hammers started falling. Monsanto had been facing thousands of lawsuits claiming their herbicide, Roundup (glyphosate), caused non-Hodgkin lymphoma. Since Bayer now owned Monsanto, they owned those lawsuits too.
By 2020, Bayer had to set aside nearly $11 billion to settle about 100,000 of those cases. And the hits kept coming. Even now, in 2026, the company is still fighting in the U.S. Supreme Court and lobbying Congress to try and stop the "financial hemorrhaging" from Roundup litigation.

Who actually calls the shots?
Since Monsanto is now just a wing of Bayer’s Crop Science division, the people in charge aren't St. Louis executives anymore. They report to the Bayer Board of Management in Germany.
The last CEO of Monsanto, Hugh Grant (no, not the actor), walked away with a massive "golden parachute" worth tens of millions of dollars when the deal closed. Since then, leadership has shifted entirely to Bayer’s internal hierarchy. If you want to talk to the "owner," you’re looking at institutional investors like BlackRock, Vanguard, and Temasek, who own the majority of Bayer’s shares.
What Happened to the Products?
Just because the name is dead doesn't mean the products are. You can still buy Roundup. You can still buy DEKALB corn or Asgrow soybeans.
Bayer kept the product brands because they are worth billions. Farmers know the brands, even if they have complicated feelings about the corporate parent. It's a classic business move: kill the parent company's name to escape the PR fire, but keep the profitable "kids" to keep the revenue flowing.
The BASF Twist
Regulators in the US and Europe were actually pretty worried about this merger. They thought Bayer would have too much power. To get the deal approved, Bayer had to sell off a huge chunk of its own existing business to a competitor called BASF.
This included:
- Their vegetable seed business.
- The LibertyLink herbicide-tolerant technology (a major rival to Roundup).
- Their digital farming platform, Xarvio.
So, ironically, to own Monsanto, Bayer had to give a leg up to one of its biggest rivals.
Is the "Monsanto" Era Really Over?
It depends on who you ask. If you're a lawyer, you're still suing "Monsanto" (the legal entity still exists on paper for liability purposes). If you're a farmer, you're buying seeds from Bayer.
The controversy hasn't gone away; it just changed its mailing address. Bayer is currently pushing hard for legislation in the U.S. to shield them from "failure to warn" lawsuits. They’ve even formed groups like the Modern Ag Alliance to fight the legal battles that Monsanto started decades ago.
Actionable Insights for the Curious
If you are trying to track where your food comes from or how these mega-corps affect your life, here is what you need to keep an eye on:
- Watch the Stock: If you want to track "Monsanto's" performance, you have to look at BAYRY (Bayer’s OTC ticker in the US) or BAYN on the German Xetra.
- Check the Label: Look for the Bayer Cross logo on agricultural products. If it says "Crop Science," that’s the ghost of Monsanto.
- Follow the Courts: The future of this "ownership" depends entirely on the U.S. legal system. If the Supreme Court rules in Bayer's favor on glyphosate labeling, the company's value could skyrocket. If they lose, the "ownership" of these assets might become a liability too heavy even for a giant like Bayer to carry.
Bayer bought a legacy of innovation, but they also bought a legacy of fire. Whether that $63 billion bet pays off is still being decided in courtrooms across the country.
