Is Biogen Inc. (BIIB) one of the Best Biotech Stocks to Invest In According to Billionaire Steve Cohen?

Biogen Inc. (NASDAQ:BIIB) is the Best Biotech Stock

On April 20, 2026, Reuters reported that Biogen Inc. (NASDAQ:BIIB) had agreed to pay up to $850 million for the exclusive Greater China rights to felzartamab. It is an experimental immune therapy developed by Chinese biotech TJ Biopharma, bringing the drug’s global commercial coverage to a close.

TJ Biopharma will receive $100 million up front. It will also add up to $750 million in milestone payments and further royalties on Greater China sales. Biogen Inc. (NASDAQ:BIIB) shares rose 1.3% in premarket trading.

Felzartamab is currently in the last stage trials for IgA nephropathy and primary membranous nephropathy. These are two kidney diseases that can lead to organ failure. China’s health regulator is separately assessing the drug for multiple myeloma.

Biogen Inc. (NASDAQ:BIIB) obtained felzartamab as part of its $1.8 billion takeover of Human Immunology Biosciences in 2024. In April 2025, the two companies launched the partnership in China. If authorities approve the medicine, Biogen Inc. (NASDAQ:BIIB) plans to oversee regional manufacture and commercialization. TJ Biopharma continues to produce it at its Hangzhou facility for myeloma.

Biogen Inc. (NASDAQ:BIIB) is a biopharmaceutical firm that works on identifying, making, and providing drugs for neurological and neurodegenerative diseases.

While we acknowledge the risk and potential of BIIB as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and doing so within a shorter time frame.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

  • 175 Teslas
  • 107 Amazons
  • 140 Metas
  • 84 Googles
  • 65 Microsofts
  • And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

  • Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
  • Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
  • Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…
