Tesla Stock (TSLA) News Today: Record-High Rally Wobbles on California Autopilot Ruling, Robotaxi Momentum and Wall Street Forecasts (Dec. 18, 2025)
Tesla, Inc. stock is back in the center of the market’s “AI-meets-autonomy” narrative on Thursday, December 18, 2025—only this time, the catalyst mix is unusually complex: a fresh regulatory threat in California tied to “Autopilot” marketing, intensifying investor focus on robotaxis, and sharply diverging analyst forecasts that range from cautious “fair value” math to trillion‑dollar upside scenarios.
The result is what TSLA investors know well: big moves, big opinions, and big questions about what Tesla really is—an automaker under pressure, or a robotics and AI platform that happens to sell cars.
Tesla stock price action: from new highs to a fast pullback
Tesla shares recently set a new all-time high around $495 before sliding sharply, with trading around the mid‑$460s to high‑$470s range as today’s headlines circulate. [1]
Several outlets tied the drop not only to Tesla-specific news but also to a broader “AI trade” wobble that hit megacap tech and AI-adjacent names—Tesla included—after the stock surged on autonomy optimism earlier in the week. [2]
The headline risk today: California puts Tesla’s “Autopilot” branding under a regulatory clock
One of the most market-moving Tesla developments being digested on Dec. 18 is California’s latest step in its long-running dispute over how Tesla markets its driver-assistance features.
According to Reuters, California’s Department of Motor Vehicles adopted a judge’s proposal to suspend Tesla’s manufacturing and sales licenses for 30 days, but then immediately stayed (paused) that penalty—giving Tesla time to remedy what the DMV says are misleading claims and names around self-driving capability. Reuters reports the DMV stayed the sales license suspension for 90 days and the manufacturing license indefinitely. [3]
Reuters also reported Tesla can avoid the suspension by submitting a statement confirming it has stopped using the “Autopilot” name for the driver-assistance software or confirming its cars can operate without active monitoring by a human. Tesla said California sales would continue uninterrupted and emphasized that the order related to terminology. [4]
Other reports summarized the same action as Tesla being given a compliance window (often described as 60 days to take corrective action) before penalties could apply—another reason the market reaction has looked more “headline volatile” than “fundamentals broken.” [5]
Why investors aren’t treating this as “business-stopping”—yet
California is Tesla’s biggest U.S. EV market, so any threat to the right to sell vehicles there is serious. But the immediate reality is that the penalty is stayed, and Tesla has procedural options (including appeal/court review timelines cited by Reuters). That reduces the risk of a sudden sales halt and helps explain why the stock’s reaction has been more about sentiment swings than panic selling. [6]
Still, for valuation, the bigger issue isn’t the short-term sales impact—it’s the potential for this dispute to spill into trust, litigation, and regulatory oversight around Full Self-Driving and robotaxi ambitions.
Robotaxi momentum is still the core bull catalyst—and it’s moving faster
Even as California turns up the scrutiny on marketing language, Tesla’s robotaxi storyline remains the engine of the stock’s rebound and premium valuation.
Reuters reported that Tesla shares jumped earlier this week after Elon Musk said the company was testing robotaxis without safety monitors in the front passenger seat, and Musk also posted that testing was underway with no occupants in the car in Austin. [7]
Reuters described Tesla’s Austin service as a limited, geo-fenced pilot launched in June using modified Model Y vehicles and previously involving a human safety monitor. That nuance matters because investors are trying to handicap a specific inflection: when Tesla can move from “assisted” pilots to scalable autonomous operations that regulators and the public accept. [8]
Investopedia likewise highlighted that Tesla’s rally to record levels has been fueled by investor willingness to view Tesla as “AI and robotics first,” with the stock’s outlook hinging on Tesla meeting ambitious targets for unsupervised FSD and robotaxi expansion. [9]
Competitive pressure check: Waymo’s fundraising chatter raises the stakes for the robotaxi race
Tesla’s autonomy narrative doesn’t exist in a vacuum. This week, Reuters reported Alphabet’s Waymo is in talks to raise funding at a valuation of at least $100 billion, with reports suggesting the round could exceed $10 billion; Bloomberg was cited as reporting Waymo could be seeking more than $15 billion at a valuation near $100 billion. [10]
Reuters also reiterated a key competitive reality: Waymo is currently the only operator in the U.S. offering paid robotaxi services with no safety drivers or in-vehicle attendants, with a fleet of more than 2,500 vehicles. [11]
For TSLA stock, this matters because Tesla’s valuation increasingly reflects expectations that it can (1) match or surpass competitors on autonomy capability, and (2) do so with a cost structure that makes robotaxis economically massive. The funding environment around Waymo signals investor appetite for the category—and the intensity of the race.
Fundamentals haven’t disappeared: Tesla’s EV demand headwinds are real
While the market is trading Tesla like an AI/autonomy platform, the company’s revenue and profit still largely come from selling vehicles—making demand softness a persistent risk.
In a Reuters exclusive earlier this month, Tesla’s U.S. sales dropped nearly 23% year-over-year in November (to about 39,800 vehicles from 51,513 a year earlier), based on Cox Automotive estimates shared with Reuters. That report noted the decline came despite Tesla rolling out cheaper “Standard” variants—highlighting the challenge of maintaining volume after the U.S. federal EV tax credit expired at the end of September. [12]
Reuters also quoted Cox Automotive’s Stephanie Valdez Streaty saying “Standard” sales appeared to cannibalize higher-end trims and that the data suggested insufficient demand to offset the post-credit slowdown—an important point because it reframes “affordable trims” from pure growth lever into margin/mixture tradeoff. [13]
This is the tug-of-war inside TSLA today: autonomy optimism lifts the multiple, while near-term EV demand creates earnings and delivery risk.
Manufacturing and vertical integration: Germany battery cell investment is a long-term signal
Tesla also put fresh emphasis on vertical integration in Europe. Reuters reported Tesla is investing an additional “three-digit million” euro amount to enable up to 8 GWh of battery cell production annually at Gigafactory Berlin starting in 2027, bringing total investments in local cell production to nearly €1 billion. [14]
For stockholders, this type of investment can be read two ways:
- Bull case: tighter supply chains, resilience, and better long-run economics if Tesla can execute local cell manufacturing efficiently.
- Bear case: more capital intensity at a time when the EV market is more price-competitive and demand is less predictable.
Corporate governance: Tesla board compensation is back in the spotlight
Another current storyline that can matter for sentiment—especially for large institutions—is governance.
Reuters reported an Equilar analysis finding Tesla’s board has earned more than $3 billion through stock awards that exceeded the value of peers’ awards at the time they were paid. Reuters highlighted large gains tied to long-held options among directors and noted Tesla suspended director compensation beginning in 2021 to settle a shareholder lawsuit alleging excessive pay. [15]
This doesn’t typically move TSLA day-to-day the way robotaxi news does, but it can influence how investors think about oversight, incentives, and risk control—especially when the company is pushing into regulated autonomy.
Wall Street forecasts for Tesla stock: why targets range from “below $400” to “$600+” (and beyond)
Tesla may be the most forecast-divisive megacap on the market right now. Recent analyst notes and media summaries illustrate just how wide the distribution is:
The “valuation is catching up” camp (more cautious)
- Morgan Stanley downgraded Tesla to Equal Weight from Overweight, while raising its price target to $425 (from $410), arguing that Tesla deserves a premium but that high expectations bring the stock closer to fair value and could make the next 12 months “choppy.” [16]
- Investopedia also summarized that Visible Alpha-tracked analysts were split across buy/hold/sell, underscoring that Wall Street conviction is not one-directional. [17]
The “autonomy acceleration” camp (more bullish)
- Investopedia reported Mizuho raised its Tesla price target to $530 from $475, citing research suggesting Tesla’s self-driving software effectiveness is improving and could help scale the robotaxi program faster and reduce the need for safety monitors. [18]
- Investopedia also referenced Wedbush as having a Street-high target of $600 and described a more aggressive bull case in which some analysts see Tesla reaching $800 by the end of next year. [19]
The “long-range scenario modeling” forecasts (higher uncertainty)
Some outlets published multi-year forecasts projecting large upside tied to autonomy and revenue expansion. For example, 24/7 Wall St. published a 2026–2030 forecast model that includes a consensus-style 12‑month target estimate and longer-horizon price scenarios extending well beyond traditional analyst timeframes. These long-range models can be useful for thinking about what needs to go right—but they’re inherently more speculative than 12‑month targets. [20]
One-year outlook: what bulls and bears are really betting on into early 2026
If you strip away the daily volatility and ask what the next year is “about” for Tesla stock, current commentary repeatedly circles back to three pressure points:
- Delivery and demand normalization after tax-credit pull-forward
The Motley Fool argued Tesla’s Q4 results could show sequential delivery declines after a pull-forward of U.S. deliveries ahead of the EV tax credit expiration, with a slower period potentially extending into early 2026 before improving later in the year. [21] - Robotaxi milestones and the credibility of “unsupervised” FSD
Tesla’s stock has been pricing in autonomy progress as a near-term catalyst, not a distant science project. Reuters’ reporting on unoccupied testing in Austin gives bulls evidence that timelines are advancing—while the California DMV action highlights how quickly regulators will challenge language that implies more autonomy than regulators believe is currently delivered. [22] - Capital intensity and execution risk
The Motley Fool cited Tesla’s CFO saying capital spending is expected to increase substantially in 2026 from roughly $9 billion in 2025, tied to production expansion and AI initiatives (including Optimus). That reinforces the idea that Tesla is entering a heavier investment phase—great if it delivers, painful if it doesn’t. [23]
What to watch next for TSLA stock
Here are the near-term and medium-term items most likely to drive Tesla shares after Dec. 18’s news cycle fades:
- California compliance steps: whether Tesla changes “Autopilot” branding and how it frames FSD capability in marketing and consumer interfaces. [24]
- Robotaxi expansion updates: whether Tesla moves beyond limited pilots and how quickly it can reduce safety-monitor requirements while staying onside with regulators. [25]
- EV demand trendlines: U.S. sales pace after the post-credit slump and the profitability implications of lower-priced trims and financing incentives. [26]
- Competitive developments: Waymo’s funding and scale signals how quickly the best-capitalized rival believes the market can expand. [27]
- Governance and oversight: board-pay scrutiny and how investors evaluate risk controls as Tesla pushes into regulated autonomy. [28]
- 2026 capex and production plans: the market will likely demand clearer “return on investment” proof as spending rises. [29]
Bottom line: Tesla stock is trading like a referendum on autonomy—not just car sales
As of Dec. 18, 2025, TSLA is being priced and traded less like a traditional automaker and more like a high‑beta proxy for autonomy and “physical AI.” That makes today’s story—California’s Autopilot ruling on one side, robotaxi progress on the other—especially potent.
For investors, the key reality is that the same theme that powers Tesla’s upside (autonomy credibility) also concentrates its risk (regulatory scrutiny, litigation exposure, and trust). In that environment, Tesla stock may continue to swing sharply—not because the market can’t make up its mind, but because it’s trying to price a future that still has multiple plausible outcomes.

Officially my last drive with Teslas Autopilot in Australia… time to level up. #tesla #fsd
