On April 9, 2026, Susquehanna updated estimates and price targets for its alternative energy coverage ahead of first-quarter earnings. As part of that, the firm lowered its price target for Fluence Energy, Inc. (NASDAQ:FLNC) from $27 to $23 while maintaining a “Positive” rating. Despite expectations being revised prior to results, this development reflects positive sentiment toward the stock.

On March 30, 2026, Needham initiated coverage of Fluence Energy, Inc. (NASDAQ:FLNC) with a “Hold” rating (without a price target), noting that while the company remains a leading pure-play grid-scale storage integrator, its early-mover advantage in domestic cell sourcing could diminish over the next 12 to 24 months as EV-to-BESS capacity conversions expand U.S. supply.

Needham also highlighted increasing execution risk as additional competitors enter the market.

Meanwhile, on March 19, 2026, Guggenheim upgraded Fluence Energy, Inc. (NASDAQ:FLNC) to “Neutral” from “Sell” with no price target, following a recent discussion with the CEO that focused on continued growth and improving profitability. The firm noted that the stock’s 51% decline since February 3, combined with a modestly improved outlook on the company’s competitive positioning, has brought valuation back to a more reasonable level.

Fluence Energy, Inc. (NASDAQ:FLNC) develops battery-based energy storage systems that leverage advanced lithium-ion technology to support EV battery supply chains and grid integration, enabling renewable energy storage and efficient power management.

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…
