Tesla’s (TSLA) massive valuation could make S&P 500 inclusion complicated
Tesla (NASDAQ: TSLA) is set to join the S&P 500 on December 21st, making it one of the newest members of the world’s most influential stock index. However, Tesla’s gigantic market capitalization, which has made it the most valuable car company globally, could make the inclusion process slightly more complicated than initially planned.
Tesla’s over $423 billion market cap will make it the largest company ever to be added to the S&P 500 Index. Putting the entire company into the new benchmark would force index-tracking funds to sell upwards of $40 billion in stock to make room for the electric car company. Because of this, the S&P’s overseer and consultant, the S&P Dow Jones Indices, is considering the option of adding Tesla to the index in phases or tranches.
After being snubbed from the index in early September, Tesla is finally getting its shot to join the S&P. But while the company is experiencing an over 400% growth in share price so far this year, adding Tesla in more than one phase seems to be the more favorable scenario. However, the S&P Dow Jones Indices will seek out feedback from investors, questioning them on which strategy is more appealing to them: adding TSLA all at once or in several chunks. It is unknown which companies will be replaced by Tesla, but the S&P plans to name them later.
Howard Silverblatt, a Senior Index Analyst at S&P Dow Jones, stated that the decision to add the electric automaker wasn’t a simple one, especially considering the magnitude of Tesla’s inclusion. “It wasn’t easy to make such an important decision, and this decision has a big impact,” he said. Silverblatt added that getting insight from investors will assist in the decision-making process.
“An open-ended dialog with investors will only help. You can’t put a company in at such a high level just like you would any other firm. The times have changed, the magnitude of the stocks that are being added has changed, too,” he added.
Tesla will end up likely being one of the top 10 largest stocks in the S&P when it joins the index on December 21st, Bloomberg reported. Estimating that it will fall in between Johnson & Johnson and Procter & Gamble Co., Tesla’s valuation would be the equivalent of the 60 smallest stocks in the benchmark. However, S&P Dow Jones uses a float-adjusted market-cap to determine the weight instead of the straight figure.
When the S&P 500 is reshuffled, which happens on a quarterly basis to rebalance the index, changes occur due to fluctuations in a company’s size. Depending on growth or a reduction of size, some stocks may move from the S&P’s small-cap index to the large-cap, or vice versa.
In Tesla’s circumstance, no company that will be removed is large enough to offset the automaker’s inclusion into the S&P 500. This is why the index’s overseer is considering adding the company in more than one tranche.
Lawrence Creatura, a portfolio manager at PRSPCTV Capital LLC, told Bloomberg that this is effectively “trading a pawn on the chessboard for a queen.”
“The size of Tesla as it’s being included in the index is much larger relative to the company that is likely to come out. That’s going to create a lot of shuffling among passive funds that track the S&P 500 explicitly,” Creatura also said.
On the news that TSLA would join the S&P on Monday evening, shares of the automaker’s stock spiked over 13% in after-hours trading. At the time of writing, TSLA shares were trading at $444.10, up over 9%.
After finally attaining the four consecutive profitable quarter threshold required to join the index, Tesla is riding a strong stream of momentum heading into the end of 2020. In its most successful year as a company yet, Tesla plans to close out 2020 with a bang by accomplishing its 500,000 vehicle delivery mark, which was set at the beginning of the year before the COVID-19 pandemic began. With increased production and growing demand, Tesla could reach a one million car a year production and delivery rate, surging the popularity and adoption of electric cars and phasing out the use of petrol-powered engines.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

OpenAI cites distrust of SpaceX in decision to drop Cursor partnership
OpenAI will cut SpaceX-owned Cursor’s model access in November, citing Musk’s history of broken contracts.
OpenAI, the company behind ChatGPT, announced late Friday that it is ending its partnership with Cursor, cutting off the coding tool’s access to its models on November 12. The move comes two weeks after SpaceX completed its $60 billion acquisition of Cursor’s parent company, Anysphere, folding the popular AI coding assistant into Elon Musk’s growing SpaceXAI division.
In a post on its website, OpenAI said the decision came down to trust, not technology. “We cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” the company wrote. OpenAI pointed to two specific incidents: X, now part of SpaceX, allegedly breaking the terms of an existing OpenAI contract after Musk bought Twitter.
That lawsuit is the backdrop for all of this. Musk cofounded OpenAI in 2015, left the board in 2018, and sued Sam Altman and Greg Brockman in 2024, arguing they abandoned the company’s nonprofit mission for profit. A federal jury sided with OpenAI in May, finding Musk waited too long to sue rather than ruling on the merits of his claims. Musk said at the time he would appeal to the Ninth Circuit, calling the outcome a “calendar technicality” rather than a real judgment.
SpaceX’s interest in Cursor predates that verdict by weeks. The company first struck a deal with Cursor in April, securing an option to acquire it for $60 billion or pay $10 billion for joint development work instead. As Teslarati reported at the time, the logic was straightforward: Cursor was paying retail prices to Anthropic and OpenAI, two of its most direct competitors, every time a developer used its product, while SpaceX had idle capacity on its Colossus supercomputer, roughly the equivalent of a million Nvidia H100 GPUs, that Cursor could use to train its own models instead. SpaceX exercised the option in June, days after its own IPO, and the deal closed in mid-August.
Once it closed, Musk moved fast. On an all-hands call with more than 1,000 Cursor employees, he reportedly told staff that SpaceXAI’s Grok was playing catchup in the AI race, unlike Tesla and SpaceX in their own markets, and singled out Anthropic as the company to catch. Cursor CEO Michael Truell now reports directly to Musk inside SpaceXAI.
Losing OpenAI’s models leaves Cursor leaning harder on Anthropic’s Claude, which has its own compute agreement with SpaceX, and on Cursor’s in-house Composer model, the one SpaceX’s compute was supposed to accelerate in the first place. OpenAI framed the November deadline as maximum notice under its contract, and said it wants to “go above and beyond” to help developers through the transition. Whether Anthropic makes the same call is now the open question in AI coding.
