Being the largest and being the most important company aren’t necessarily the same thing. Nvidia (NVDA 1.00%) is the largest company by a fairly wide margin — at the time of this writing, it has about a $500 billion lead over second-place Alphabet — but does that mean it’s also the most important?

Let’s take a look to see how important Nvidia is, and if the world could survive without it.

Nvidia has several rising competitors

Nvidia makes the most popular computing chips for artificial intelligence (AI) right now: graphics processing units (GPUs). These devices can process multiple calculations in parallel, making them ideal for tasks that require intense computing power, like AI. However, it’s not the only company that makes them. AMD is also an avid GPU maker, and even though its market share is far smaller than Nvidia’s, it’s still a potent competitor.

Additionally, there are other computing chips starting to rise in popularity. One is made by Alphabet and Broadcom, the Tensor Processing Unit (TPU). This chip, designed in collaboration with the two companies, is a formidable competitor to Nvidia’s GPU, and multiple firms outside of Alphabet are now starting to buy it from Alphabet to deploy in addition to Nvidia GPUs.

So, if someone snapped their fingers and made Nvidia disappear, I think the world could figure out something to replace it. But, there’s another consideration.

Being the most important company doesn’t always mean it’s irreplaceable. Nvidia is incredibly important to other things, like investment indexes. Nvidia is a major component of indexes like the S&P 500 — it makes up about 7.5% of the total index. So, if Nvidia were to cease to exist, the S&P 500 index would be that much smaller the next day. That makes it very important to the index, and Nvidia’s continued success is key to future gains.

During its last quarter, Nvidia’s revenue rose at an 85% pace. That’s incredible, and it’s one of the reasons why it is the world’s largest company. But if Nvidia’s growth starts to meaningfully decline, the stock could sell off and drag the whole market with it.

That makes Nvidia incredibly important to the success of investment portfolios around the world, so I’d consider Nvidia an important business from that standpoint.

Nvidia’s success is critical to every investor, whether they realize it or not. Keeping a tab on Nvidia’s results is a good move for every investor, as it has a greater effect on the success of everything than most realize.

On Thursday, a New Glenn rocket belonging to Jeff Bezos’ Blue Origin exploded during an engine-firing test at the launch pad in Cape Canaveral, ahead of a satellite launch scheduled for next week.

Blue Origin also planned to use the rocket to launch landers to the moon for NASA, delivering payloads and astronauts to the surface. SpaceX is jockeying to be selected by NASA for the lunar mission too, and may emerge as the only remaining option to meet an ambitious schedule.

The vulnerability highlights the multiple steps—and contractors—a lunar landing would entail. While NASA successfully sent astronauts around the moon last month in a Lockheed Martin Orion capsule launched by Boeing’s massive Space Launch System rocket, landing on the moon’s surface requires a separate spacecraft.

Next year, NASA plans to send astronauts into Earth orbit via the Orion and Space Launch System as part of its Artemis III mission. While in orbit, NASA expected to dock the Orion with either SpaceX’s lunar lander, a variant of the Starship, and/or Blue Origin’s lander, the Blue Moon.

But the New Glenn is supposed to launch the Blue Moon into space, and the rocket is now grounded as the cause of the explosion is investigated. Just days before the explosion, NASA awarded Blue Origin launch contracts, including one this fall for a Blue Moon lander mission to put NASA payloads on the surface.

“Blue Origin’s inability to launch Blue Moon anytime soon is likely to put the company out of the running for Artemis III,” wrote Wendy Whitman Cobb, a professor at the U.S. Air Force School of Advanced Air and Space Studies, in the Conversation on Friday. “This setback means that Artemis III, and NASA’s entire lunar exploration program, is likely to be dependent on SpaceX for the time being.”

Meanwhile, SpaceX is still developing the Starship. While a next-generation version of the giant rocket completed a test flight this month that was largely successful, more work needs to be done to produce a lunar-lander variant.

Whitman Cobb warned that if SpaceX can’t get Starship ready in time, then NASA may need to delay the Artemis III orbital-docking test by a year to 2028—meaning the Artemis IV mission to put astronauts on the moon will miss its 2028 timeline.

Further delays could also open the door again to Blue Origin, if it can get the New Glenn back on track soon and test out its lunar lander.

But a mishap highlighting NASA’s reliance on SpaceX could not come at a better time for CEO Elon Musk, whose company is expected to go public on June 12 in what will likely be the largest IPO ever. SpaceX is seeking to raise up to $75 billion at a valuation of $1.75 trillion or more. 

Since its founding in 2002, SpaceX has taken over the market. It claimed more than 80% of global rocket launches last year and has over 10,000 Starlink satellites in orbit, providing space-based internet connections to businesses and militaries.

In addition to serving NASA, SpaceX is a top launch provider for the Pentagon, which is also looking to the company to help develop President Donald Trump’s “Golden Dome” missile-defense shield.

“It’s a truly unique business with the deepest moat that exists today,” an investor told the Financial Times recently.

Starlink is SpaceX’s cash cow as the satellite business more than doubled its profit last year to $4.4 billion. Blue Origin has plans to compete in that arena as well by building out its constellation of Leo satellites. But the New Glenn explosion, which also damaged Blue Origin’s launchpad, has set that back as well.

Walter Isaacson, an author and an advisory partner at Perella Weinberg, pointed out that the New Glenn accident not only puts Blue Origin behind SpaceX in the lunar mission but further behind its rival in the satellite business.

“SpaceX is way ahead, and the loss of this launchpad on during this test means that it’s going to be harder for Blue Origin to catch up in the next two or three years with low-Earth-orbit communication satellites,” he told CNBC on Friday.
