Elon Musk’s two public companies shed roughly $456 billion in market value in two trading days. Tesla and SpaceX slid as the 2026 midterm results settled in, and Thursday, November 5 was the worst session of the stretch. CNBC, MarketWatch and Investor’s Business Daily all covered the drop. The combined Tesla SpaceX market cap fell from about $3.5 trillion on Tuesday night to about $3.04 trillion on Thursday night.
The first reports put the loss at more than $420 billion, measured from Tuesday’s close. By Thursday’s close the tally had grown to about $456 billion. Our earlier coverage of Musk’s reported midterm spending and the first share-price drops caught the opening leg. This piece follows the full two-day move, checks the arithmetic, and sorts what is confirmed from what is still speculation.
One caution up front. The reports describe investor worry about congressional probes and tougher regulation. They do not describe any actual investigation, subpoena or rule. That gap between fear and fact is the story, and it shapes everything below.

The $456 Billion Two-Day Loss in Brief
The headline figures come from the coverage and from Dow Jones Market Data, which the reports cite for the split between the two companies. Dow Jones Market Data attributed about $216 billion of the loss to Tesla and about $240 billion to SpaceX. Add those together and you land on the $456 billion total that circulated by Thursday evening.
On Thursday alone, Tesla shares fell about 11% and SpaceX shares fell about 9%. Those are large single-day moves for companies of this size. A one-day drop of 11% on a company worth well over a trillion dollars erases more value in hours than most listed companies are worth in total.
By Thursday night, reported market capitalizations stood at about $1.36 trillion for Tesla and about $1.68 trillion for SpaceX. SpaceX is the larger of the two by roughly $320 billion on those numbers. It also took the bigger share of the damage, about 53% of the two-day loss against Tesla’s 47%.
The decline did not happen in isolation. The coverage ties it to a wider technology-sector sell-off, which matters when you try to separate Musk-specific fear from a general risk-off mood. We return to that below.
Reported Numbers for Tesla and SpaceX
The table below lays out what the coverage reports and adds a few figures we derived ourselves. Derived columns are our arithmetic, not reported data, and they carry rounding error because the underlying percentages are described as approximate.
Read the derived column with care. Tesla’s implied Tuesday value of about $1.58 trillion comes from adding the $216 billion loss to the $1.36 trillion Thursday-night value. SpaceX works the same way. The two implied figures sum to about $3.5 trillion, which matches the reported Tuesday-night total, so the sets of numbers agree with each other.
Checking the Math From $3.5 Trillion to $3.04 Trillion
The move from $3.5 trillion to $3.04 trillion is a drop of about $460 billion on the rounded totals. The $456 billion figure is the more precise one, built from the two company-level numbers. Rounding explains the small gap, and neither number contradicts the other.
The more interesting question is how the loss split across the two days. The coverage gives Thursday percentages but, in the material we have, no Wednesday close. We can back into a rough answer. If Tesla fell about 11% on Thursday to end near $1.36 trillion, it started Thursday near $1.53 trillion. That means Thursday cost it around $168 billion and Wednesday around $48 billion. SpaceX works out to about $166 billion on Thursday and about $74 billion on Wednesday.
Treat this table as an estimate. The inputs are rounded and other outlets may measure from slightly different closing prices. The pattern still holds up: roughly three-quarters of the damage landed on Thursday, which suggests the sell-off accelerated as the political picture clarified instead of fading after the first reaction.
Why the Midterm Results Hit Musk’s Companies
According to the reports, the Democratic Party won control of both the House of Representatives and the Senate. Investors, the same coverage says, worried that Musk could face new congressional probes and that his companies could face stricter regulation. Those are the two stated reasons, and they are the only ones the fact base supports.
Control of both chambers matters because it hands committee gavels and subpoena power to the other party. A unified opposition Congress can open inquiries, call executives to testify, and hold up nominations or funding that touch a company’s business. Markets price that possibility before anything concrete happens, which is why share prices can fall on a feared outcome with no new fact on the table.
Musk is an unusually exposed target for that kind of repricing. He is the public face of two large companies, and our reporting on hardware oversight risk under a Democratic Congress already flagged that his firms build physical products that regulators can inspect, test and restrict. Vehicles, rockets and satellites all sit inside existing federal regimes. A hostile committee does not need new laws to make life harder. It can use hearings and letters to raise the cost of doing business.
Nothing in the available reporting says such steps have started. The market is pricing a probability, not an event.
What Is Confirmed and What Is Not
Because this story moves fast and invites rumor, we separate the record into two columns. The confirmed items come from the coverage in CNBC, MarketWatch, Investor’s Business Daily and the Dow Jones Market Data figures those reports cite. The unconfirmed items are things readers may assume but that no source establishes.
The last row deserves emphasis. The reporting contains no verified quote from Musk, either company, a named investor, an analyst or a government official. We therefore skip the usual expert-quotes section. Any article that fills that space with colorful commentary is guessing.
The Broader Technology Sell-Off
The coverage places the Tesla and SpaceX losses alongside a wider technology sell-off. That context cuts two ways. It suggests part of the move reflects general nerves about how a divided Washington treats big tech, and it complicates any attempt to pin the whole $456 billion on Musk-specific fears.
Compare that with the mood a few days earlier. We covered a different post-election story, Big Tech eyeing a $750 billion gain as Democrats won Congress, where traders read the result as manageable for large platforms. The two readings are not contradictory. Investors can decide that divided government is fine for software and advertising giants while deciding it is riskier for a founder with a long list of regulatory touchpoints.
For anyone trying to size the Musk-specific piece, the useful test is relative performance. If the broader sell-off was mild and Tesla and SpaceX fell 9% to 11% in a day, the idiosyncratic share is large. The reports describe the wider decline but, in the material available to us, do not give index-level numbers. We will not guess at them. Readers who want to run the comparison should pull the index closes for November 4 and 5 and set them against the company moves above.
Tesla’s Exposure: Vehicles, Batteries and Factories
Tesla lost about $216 billion of value and ended Thursday near $1.36 trillion. As a hardware company, it faces oversight on several fronts at once. It sells vehicles that fall under federal safety rules, and it sells home batteries that sit under their own product and installation standards. We have covered recent consumer-facing items such as the Powerwall replacement cases and driver-assistance changes on this site, and each shows how a product-level story can become a regulatory one.
The 11% Thursday decline is the larger of the two single-day moves. One reasonable reading is that Tesla carries more scrutiny-sensitive product lines than SpaceX, while another is that Tesla trades with a larger retail and momentum following that amplifies swings. The reporting does not say which, and we cannot settle it from the available facts.
What we can say is that a Tesla share price moves the cost of capital for its hardware plans. A company that funds factories, battery supply and new vehicle programs partly through equity value feels a lower stock price in its negotiating position with suppliers and in its ability to use stock for hiring. A paper loss of $216 billion is not cash leaving the business, but it changes the mood in every planning meeting.
SpaceX’s Exposure: Rockets, Satellites and Contracts
SpaceX lost about $240 billion, the bigger share of the damage, and closed Thursday near $1.68 trillion after a roughly 9% single-day fall. Its business rests on launch hardware and satellite networks, and its work touches federal agencies in ways Tesla’s does not. Much of the space industry runs through Washington in one way or another, from launch contracts to spectrum rules.
That dependence is a plausible reason investors reacted. An opposition Congress holds the purse strings and oversight authority over the agencies that buy launch services. It also holds a say over spectrum and satellite policy. We tracked how the company’s mobile ambitions rely on hardware partners in our look at Qualcomm’s 5G deal with SpaceX and its 2027 start, a program that needs regulatory goodwill as much as chips.
Again, no specific action against SpaceX appears in the reporting. The $240 billion figure reflects what investors fear might happen, filtered through a stock that was valued at roughly $1.92 trillion two days earlier by our derived estimate.
Competitive Comparison: Which Musk Company Took the Harder Hit
Measured in dollars, SpaceX lost more. Measured in single-day percentage on Thursday, Tesla lost more. Measured over the full two days using our derived Tuesday values, Tesla fell about 13.7% and SpaceX about 12.5%. The three yardsticks point in slightly different directions, so no single company has a clean claim to the worse outcome.
Compared with other hardware makers, the pattern is clear in principle even without peer numbers. Legacy automakers, other launch providers and satellite operators do not carry one founder whose political profile drives the equity story. Whether those peers gained or fell during the same two days is outside the reporting we hold, so we make no claim about it. The point for buyers is structural: concentration of attention in one person raises the odds of outsized moves in both directions.
Historical Context: Washington Power Shifts and Mega-Cap Stocks
Mega-cap stocks often wobble when control of Congress changes hands, because investors reprice the odds of hearings, new rules and spending fights. The pattern is not unique to Musk. Large technology firms have faced committee scrutiny across several Congresses, and executives have been called to testify on topics ranging from competition to safety.
What stands out here is scale and speed. A $456 billion combined loss in two sessions is a large number by any standard, and it arrived before the new Congress has even been seated. That ordering is the tell. Investors are trading the expectation of conflict, not conflict itself. We laid out the political side of that expectation in our report on Democrats’ scrutiny of Musk and the two camps of tech CEOs, which explains why Musk draws more attention than most peers.
History also offers a mild counterweight. Share-price reactions to feared political events have often faded when the feared events failed to materialize. They have also stuck when real action followed. We cannot tell from the reporting which path this will take, and anyone who says they can is selling a view, not a fact.
What Hardware Buyers and Suppliers Should Watch
For people who buy, build or supply hardware tied to these companies, the market-cap loss is a signal to monitor, not a reason to panic. A drop in equity value does not change a delivery schedule, a warranty or a launch manifest. It does change how much attention executives, lenders and partners pay to risk. Our hardware coverage hub follows the product side of these stories.
Three practical watch items stand out. First, any formal notice from a congressional committee, since that would turn fear into a documented event. Second, any statement from Tesla or SpaceX in their own words, since none exists in the reporting today. Third, regional policy that touches physical infrastructure. Our report on the Texas data center pause and the Tesla and SpaceX share drop shows how a local policy item can ripple into these stocks.
Suppliers with heavy exposure to either company should also check how much of their own valuation rides on contracts tied to these names. A supplier does not need a regulatory finding to feel pressure. A cautious customer that delays an order can do the same job.
Five Predictions for the Next Few Weeks
These are our assessments, not reported facts. We label them as such because the evidence base is thin and the situation can change in a day.
- Volatility stays high until a concrete item appears. With no confirmed probe or rule, the shares will likely keep reacting to headlines. A single letter from a committee could move them more than the underlying business news would.
- Committee activity starts as paperwork, not hearings. New majorities usually begin with information requests before they schedule high-profile sessions. If that happens here, expect the first signals to be document requests that surface through press leaks.
- SpaceX stays the larger company by value. The roughly $320 billion gap between the two on Thursday night is wide enough that ordinary daily swings should not close it in the short term.
- Both companies add or sharpen risk language. Their next regulatory filings are a natural place to describe political and oversight risk. That would not prove a probe exists, only that management sees the risk as worth disclosing.
- The broader sector recovers faster than the Musk names. If the general technology sell-off was a one-off reaction, large platforms may bounce sooner than companies tied to a single polarizing founder. This is the least certain call on the list.
Each prediction carries real uncertainty, and a surprise from either side could flip any of them. We will update this analysis if a named source confirms an investigation, a regulatory action or an on-record company response.
How to Read a Market-Cap Headline Like This One
Market-cap headlines reward a few habits. Start with the baseline. A loss quoted from Tuesday’s close counts everything that happened after the polls closed, including moves that had nothing to do with the later news. That is why the figure shifted from more than $420 billion to about $456 billion as Thursday’s session finished.
Next, check whether the number is a sum or a single measure. Here it is a sum of two companies, so a reader who wants to judge either business should look at the separate figures. Tesla’s $216 billion and SpaceX’s $240 billion tell different stories about who bore the brunt.
Finally, ask what has actually changed in the business. In this case the answer, per the reporting, is nothing concrete. Prices fell because investors changed their expectations. That can reverse as fast as it arrived, or it can harden into a lasting discount if a probe or rule appears. Either way, a paper loss of this size is a statement about sentiment first and operations second.
The Takeaway for Readers
The takeaway: about $456 billion of market value left Tesla and SpaceX in two trading days, and the stated reason is investor fear, not a documented government action. The figures are solid. The explanation is an inference built on worries that reporters attributed to investors.
If you hold either stock, the right question is whether the feared scrutiny becomes real. If you buy or build hardware connected to these firms, the right question is whether lower valuations change behavior at your counterparty. Neither question has an answer in today’s reporting. Until a named official or company speaks on the record, treat every dramatic claim about what comes next as unproven.
FAQ: Tesla and SpaceX After the Midterms
How much did Tesla and SpaceX lose after the midterms?
Coverage first cited more than $420 billion in combined market value over two trading days from Tuesday’s close. By the close on Thursday, November 5, 2026, the reported total was about $456 billion. Dow Jones Market Data split it into about $216 billion for Tesla and about $240 billion for SpaceX.
How far did each stock fall on Thursday?
Tesla shares were down about 11% and SpaceX shares were down about 9% on Thursday, according to the reports.
What are Tesla and SpaceX worth now?
Reported market capitalizations on Thursday night were about $1.36 trillion for Tesla and about $1.68 trillion for SpaceX. Together that is roughly $3.04 trillion, down from about $3.5 trillion on Tuesday night.
Why did the stocks drop?
Reports said investors feared that Elon Musk could face new congressional probes and that his companies could face stricter regulation after the Democratic Party won both chambers of Congress. The drop also came during a broader technology sell-off.
Is Congress investigating Musk, Tesla or SpaceX?
No specific investigation is confirmed in the reporting we reviewed. The coverage describes investor concern about possible probes, not an announced one.
Did Musk, Tesla or SpaceX comment on the drop?
The available reporting contains no verified on-record statement from Musk or either company. We have not included any quotes for that reason.
Which company lost more, Tesla or SpaceX?
SpaceX lost more in dollars, at about $240 billion against Tesla’s $216 billion. Tesla fell by a larger percentage on Thursday, at about 11% against about 9%.
Does the market-cap loss affect buyers of Tesla products or SpaceX services?
Not directly. A lower share price is a paper loss and does not change product warranties, delivery schedules or service terms. It can influence how the companies and their partners weigh risk, so it is worth watching for any follow-on announcements.
