SpaceX ships Starship’s 200th upgraded Raptor engine
A day after revealing the completion of the 200th Falcon upper stage and Merlin Vacuum engine, SpaceX has announced that it also recently finished building Starship’s 200th upgraded Raptor engine.
Starship – and Raptor, by extension – has yet to reach orbit and is likely years away from scratching the surface of the established success and reliability of the Falcon upper stage and MVac. But compared to MVac, Raptor is more complex, more efficient, more than twice as powerful, experiences far more stress, and is three times younger.
And Raptor 2 isn’t the first version of the engine. Before SpaceX shipped its first Raptor 2 prototype, it manufactured 100 Raptor 1 engines between the start of full-scale testing in February 2018 and July 2021. By late 2021 or early 2022, when Raptor 2 took over, the total number of Raptor 1 engines produced likely reached somewhere between 125 and 150 – impressive but pale in comparison to SpaceX’s Raptor 2 ambitions.
From the start, Raptor 2’s purpose was to make future Raptors easier, faster, and cheaper to manufacture. The ultimate goal is to eventually reduce the cost of Raptor 2 production to $1000 per ton of thrust, or $230,000 at Raptor 2’s current target of 230 tons (~510,000 lbf) of thrust. As of mid-2019, Musk reported that each early Raptor 1 prototype cost “more” than $2 million for what would turn out to be 185 tons of thrust (~$11,000 per ton). It’s not clear if that ever appreciably changed.
In response, SpaceX strived to make Raptor 2 simpler wherever possible, removing a large part of the maze of primary, secondary, and tertiary plumbing. In 2022, CEO Elon Musk confirmed that SpaceX had even removed a complex torch igniter system for Raptor 2’s main combustion chamber. All that simplification made Raptor 2 much easier to build in theory, and SpaceX’s production figures have more than confirmed that theory. Despite those simplifications, SpaceX was also able to boost Raptor 2’s thrust by 25% by sacrificing just 1% of Raptor 1’s efficiency.
Beginning with its first delivery in February 2018, SpaceX produced the first 100 Raptor 1 engines in about 36 months. In the first 11 to 12 months of Raptor 2 production, SpaceX has delivered 200 engines. That translates to at least six times the average throughput, but the true figure is even higher. In June 2019, Musk stated that SpaceX was “aiming [to build a Raptor] engine every 12 hours by end of year.” As is usually the case, that progress took far longer to realize. But in October 2022, a senior NASA Artemis Program official revealed that SpaceX recently achieved sustained production of one Raptor 2 engine per day for a full week.
Such a high rate – likely making Raptor one of the fastest-produced orbital-class rocket engines in history – is required because SpaceX’s next-generation Starship rocket needs a huge amount of engines. The Starship upper stage currently requires three sea-level-optimized Raptors and three vacuum-optimized Raptors, and SpaceX has plans to increase that to nine engines total. Starship’s Super Heavy booster is powered by 33 sea-level Raptors.
Orbital-class versions of Starship and Super Heavy have never flown, let alone demonstrated successful recovery or reuse, so SpaceX has to operate under the assumption that every orbital test flight will consume 39 Raptors. Even after the reuse of Super Heavy boosters or Starships becomes viable, taking significant strain off of Raptor demand, SpaceX wants to manufacture a fleet of hundreds or even thousands of Starships and a similarly massive number of boosters. To outfit that massive fleet, SpaceX would have to mass-produce orbital-class Raptor engines at a scale that’s never been attempted.
But it will likely be years – if not a decade or longer – before SpaceX is in a position to attempt to create that mega-fleet. If the Raptor 2 engines SpaceX is already building are modestly reliable and reusable, and it doesn’t take more than 5-10 orbital test flights to begin reusing Starships and Super Heavy boosters, a production rate of one engine per day is arguably good enough to support the next few years of realistic engine demand.
SpaceX’s first orbital Starship launch attempt could occur as early as December 2022, although Q1 2023 is more likely. SpaceX currently has permission for up to five orbital Starship launches per year out of its Starbase, Texas facilities and will likely try to take full advantage of that with several back-to-back test flights in a period of 6-12 months.

Elon Musk’s xAI closes upsized $20B Series E funding round
xAI announced the investment round in a post on its official website.
xAI has closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development.
xAI announced the investment round in a post on its official website.
A $20 billion Series E round
As noted by the artificial intelligence startup in its post, the Series E funding round attracted a diverse group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group, among others.
Strategic partners NVIDIA and Cisco Investments also continued support for building the world’s largest GPU clusters.
As xAI stated, “This financing will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products reaching billions of users, and fuel groundbreaking research advancing xAI’s core mission: Understanding the Universe.”
xAI’s core mission
Th Series E funding builds on xAI’s previous rounds, powering Grok advancements and massive compute expansions like the Memphis supercluster. The upsized demand reflects growing recognition of xAI’s potential in frontier AI.
xAI also highlighted several of its breakthroughs in 2025, from the buildout of Colossus I and II, which ended with over 1 million H100 GPU equivalents, and the rollout of the Grok 4 Series, Grok Voice, and Grok Imagine, among others. The company also confirmed that work is already underway to train the flagship large language model’s next iteration, Grok 5.
“Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote.
Tesla (NASDAQ: TSLA) stock received a price target update from Pierre Ferragu of Wall Street firm New Street Research, citing the company’s growing lead in self-driving and autonomy.
On Tuesday, Ferragu bumped his price target from $520 to $600, stating that the consensus from the Consumer Electronics Show in Las Vegas was that Tesla’s lead in autonomy has been sustained, is growing, and sits at a multiple-year lead over its competitors.
CES 2026 validates Tesla’s FSD strategy, but there’s a big lag for rivals: analyst
“The signal from Vegas is loud and clear,” the analyst writes. “The industry isn’t catching up to Tesla; it is actively validating Tesla’s strategy…just with a 12-year lag.”
The note shows that the company’s prowess in vehicle autonomy is being solidified by lagging competitors that claim to have the best method. The only problem is that Tesla’s Vision-based approach, which it adopted back in 2022 with the Model 3 and Model Y initially, has been proven to be more effective than competitors’ approach, which utilizes other technology, such as LiDAR and sensors.
Currently, Tesla shares are sitting at around $433, as the company’s stock price closed at $432.96 on Tuesday afternoon.
Ferragu’s consensus on Tesla shares echoes that of other Wall Street analysts who are bullish on the company’s stock and position within the AI, autonomy, and robotics sector.
Dan Ives of Wedbush wrote in a note in mid-December that he anticipates Tesla having a massive 2026, and could reach a $3 trillion valuation this year, especially with the “AI chapter” taking hold of the narrative at the company.
Ives also said that the big step in the right direction for Tesla will be initiating production of the Cybercab, as well as expanding on the Robotaxi program through the next 12 months:
“…as full-scale volume production begins with the autonomous and robotics roadmap…The company has started to test the all-important Cybercab in Austin over the past few weeks, which is an incremental step towards launching in 2026 with important volume production of Cybercabs starting in April/May, which remains the golden goose in unlocking TSLA’s AI valuation.”
Tesla analyst breaks down delivery report: ‘A step in the right direction’
Tesla has transitioned from an automaker to a full-fledged AI company, and its Robotaxi and Cybercab programs, fueled by the Full Self-Driving suite, are leading the charge moving forward. In 2026, there are major goals the company has outlined. The first is removing Safety Drivers from vehicles in Austin, Texas, one of the areas where it operates a ride-hailing service within the U.S.
Ultimately, Tesla will aim to launch a Level 5 autonomy suite to the public in the coming years.
