A Timeline of Jeff Bezos and Elon Musk's Feud (2024)

The longtime rivalry between Tesla CEO Elon Musk and Amazon founder Jeff Bezos spans over 15 years.

Publicly butting heads since 2004, the billionaires have taken part in unfriendly discourse over the years. While the two have competed in having the highest net worth, they've most notably engaged in a years-long space race with their respective reusable rocket companies.

Musk founded Space Exploration Technologies, aka SpaceX, in 2002. Two years prior, Bezos launched Blue Origin in 2000. Since the companies' inceptions, they have fiercely competed to be the first since 1972 to put humans back on the Moon.

The public dispute between the two remained quiet from 2004 until 2013 when Blue Origin filed a protest against SpaceX in an attempt to win over NASA and its Kennedy Space Center launchpad. This marked one of the many legal actions the CEOs have taken over the years.

In addition to filing lawsuits, Musk and Bezos have infamously turned to Twitter to shade each other — in which the SpaceX founder has been known to call the Blue Origin CEO a "copycat," among penning jabs at his Amazon pursuits.

2004: Elon Musk and Jeff Bezos butt heads during a dinner meet up

Musk and Bezos met for dinner in 2004 to discuss their reusable rocket ambitions, prior to any launches taking place. Though their companies were both in their beginning stages, the two CEOs seemingly didn't get along from the start.

"I actually did my best to give good advice, which he largely ignored," Musk said of Bezos after a dinner together, per Christian Davenport's book, The Space Barons.

In 2021, The Hustle's Trung Phan tweeted a photo taken of both Musk and Bezos at the 2004 dinner. Musk responded to the photo, writing: "Wow, hard to believe that was 17 years ago!"

Sept. 3, 2013: Blue Origin files protest against SpaceX's attempt to lease NASA's launchpad

Both Bezos' Blue Origin and Musk's SpaceX wanted to lease NASA's Launch Complex 39A at Kennedy Space Center in Florida, each sending formal proposals to the space agency vying for the spot.

Blue Origin requested to convert it into a commercial pad that would be accessible to all launch companies, whereas SpaceX wanted to lease it exclusively for its Falcon family of rockets (though later said it would be open to sharing), per Space News.

Blue Origin later filed a protest to prevent SpaceX from using the pad and Musk lashed out at Bezos' company and the United Launch Alliance, saying that they were using a "phony blocking tactic" to hinder SpaceX's expansion plans.

Ultimately, SpaceX beat out Blue Origin to take over the launch pad on Dec. 13, a day after the Government Accountability Office rejected Blue Origin's protest.

"NASA said it continued evaluating the two companies' proposals for using the pad even while the GAO deliberated over the protest," reported ABC News.

Aug. 25, 2014: Elon Musk's SpaceX protests a patent awarded to Jeff Bezos' Blue Origin

On March 25, 2014, Blue Origin's patent for landing rockets on water was approved — though later in August, SpaceX filed a protest claiming the invention was an "old hat" in the rocket-engineering industry.

In the end, the U.S. Patent Trial and Appeal Board sided with SpaceX, leading to Blue Origin's cancellation of the majority of claims in the patent.

Nov. 25, 2015: Elon Musk tweets about Jeff Bezos' reusable rocket news

When Blue Origin's New Shepard space vehicle successfully flew to space, Bezos tweeted the celebratory news. Unamused, Musk responded to the tweet noting that the accomplishment was nothing new.

"@JeffBezos Not quite 'rarest.' SpaceX Grasshopper rocket did 6 suborbital flights 3 years ago & is still around," Musk wrote.

Meanwhile, Bezos hit back at Musk in a similar fashion after SpaceX landed its Falcon 9 spacecraft. "Congrats @SpaceX on landing Falcon's suborbital booster stage. Welcome to the club!" the Blue Origin CEO wrote.

Feb. 23, 2019: Jeff Bezos throws subtle shade at Elon Musk and his desire to colonize mars

Bezos seemingly dissed Musk during a private lecture moderated by Space News writer Jeff Foust in February 2019. While the conversation primarily centered around his future plans for his rocket company Blue Origin, in addition to his desire to make space a place where people can live, he didn't fail to hint at Musk, indirectly referencing his ambition to colonize mars.

"We have sent robotic probes now to every planet in this solar system, and this is the best one," Bezos said of Earth. "My friends who want to move to Mars? I say do me a favor: Go live on the top of Mount Everest for a year first and see if you like it, because it's a garden paradise compared to Mars."

When the Financial Times tweeted the news, Musk left a reply in a similar fashion to his April 2019 tweet. "@JeffBezosis a copy 🐈 haha," he wrote.

Musk nabbed a major victory over Bezos in their ongoing space race when NASA chose SpaceX as the primary company to construct a spacecraft that will send humans to the Moon.

Winning a $2.89 billion contract with the space agency, Musk's SpaceX is now tasked to build a lunar lander that will put humans on the Moon for the first time since December 1972.

The company's spacecraft will be part of NASA's Artemis mission, which plans to put the first woman and next man on the Moon in 2024 and establish a sustainable human lunar presence by the end of the decade.

Not long after NASA awarded SpaceX a multi-billion dollar contract to send humans back to the Moon, Bezos penned a protest to the Government of Accountability Office against the agency.

The 50-page complaint accused NASA of "moving goalposts" for the companies competing for a $2.89 billion lunar lander contract to transport astronauts to the Moon.

"Their decision eliminates opportunities for competition, significantly narrows the supply base, and not only delays, but also endangers America's return to the Moon," Blue Origin said in a statement at the time.

In response to a New York Times reporter's Tweet about the complaint, Musk mockingly tweeted: "Can't get it up (to orbit) lol."

The complaint was filed in the US Court of Federal Claims, challenging NASA's evaluation in an attempt to overturn the space agency's decision.

A spokesperson for Blue Origin confirmed the lawsuit: "We firmly believe that the issues identified in this procurement and its outcomes must be addressed to restore fairness, create competition, and ensure a safe return to the Moon for America," Blue Origin said. The company added that it's looking to "remedy the flaws in the acquisition process found in NASA's Human Landing System."

Aug. 27, 2021: Jeff Bezos' Amazon protests SpaceX's effort involving Starlink

Amazon sent a protest letter to the Federal Communications Commission arguing that SpaceX's second-generation Starlink network breaks the rules on satellite deployment. Note that the complaint came as Amazon was simultaneously developing its own satellite internet system, titled Project Kuiper.

About a week after Musk was named Time's Person of the Year, the billionaire didn't hold back when speaking about fellow billionaire Bezos in an interview with the Financial Times.

Musk said in the interview that while his fellow billionaire has "reasonably good engineering aptitude," he feels Bezos "does not seem to be willing to spend mental energy getting into the details of engineering."

"[He] does take himself a bit too seriously," he added of Bezos. "In some ways, I'm trying to goad him into spending more time at Blue Origin so they make more progress. As a friend of mine says, he should spend more time at Blue Origin and less time in the hot tub."

The interview was published days after Blue Origin sent its third crewed mission to space, which included Good Morning America's Michael Strahan.
