Tesla and SpaceX shares fall after Democrats win Congress and Texas races

Market reaction after the election

Beinsure reports that Tesla and SpaceX shares fell sharply on November 4, 2026, after Democrats won both chambers of Congress and posted major victories in Texas, a state where Elon Musk has focused much of his business and political activity. Tesla dropped more than 5% shortly after the opening bell, while SpaceX, which completed its initial public offering in June, initially declined by more than 7%. Both stocks later recovered part of those losses. The declines came as the broader U.S. market moved higher, with the Dow Jones Industrial Average rising by more than 1,200 points as investors reacted positively to the idea of divided government and less political uncertainty.

Musk’s election spending and the Texas losses

According to Beinsure, Musk was the biggest individual donor in the election cycle and spent at least $474 million supporting Republican candidates and organizations. The article says roughly $224 million of that total went to Texas. Despite that spending, Republicans lost important races there, including the Senate contest, where Republican candidate Ken Paxton lost to Democrat James Talarico. Musk also backed Republican-aligned political groups such as America PAC and the Senate Leadership Fund. Beinsure says he gave about $158 million to the Senate Leadership Fund in September alone.

The article says Talarico’s win made him the first Democrat elected to the U.S. Senate from Texas since 1988. It also reports that Democrat Gina Hinojosa defeated incumbent Governor Greg Abbott, making her the state’s first Democratic governor since 1995. Beinsure says Musk had given about $5 million to Abbott’s reelection effort. Democrats also won the lieutenant governor’s and attorney general’s races, which the article says changed the political landscape in a state that has attracted major investment from Musk’s companies.

Why the election matters for Tesla and SpaceX

Beinsure says Texas is home to the headquarters of Tesla, SpaceX and X, along with major manufacturing, aerospace and technology operations. Because of that, the election results could have direct business consequences beyond Musk’s own political activity. The article says Democratic control of Congress and the new balance of power in Texas could bring more scrutiny of Musk’s companies, including their proposed merger, government contracts and plans for AI infrastructure.

Musk responded to the Republican defeats on X with two posts. He wrote, “Guess my election-interfering space lasers didn’t work this time,” and later posted, “Data centers in space looking pretty appealing right now.” Beinsure says these remarks came amid rising criticism of large AI data centers, especially over electricity use, water needs and effects on local infrastructure.

Merger plans and possible regulatory scrutiny

Beinsure reports that Tesla and SpaceX have been exploring a merger that could combine Tesla’s electric vehicles, robotics and artificial intelligence operations with SpaceX’s launch services, satellite communications and computing infrastructure. The article says such a deal would bring together two of Musk’s most valuable businesses and could create one of the world’s largest publicly traded companies.

At the same time, Beinsure says Democratic lawmakers have already raised concerns about Musk’s influence over federal agencies, government contracts and technology infrastructure. The article says congressional investigations could focus on related-party governance, competition, federal procurement and shareholder interests. Congress cannot block a merger on its own, but hearings, investigations and requests for information could still make the process more difficult. The article also says analysts expect possible disputes over valuation and ownership structure, and that shareholders would need to assess how the companies’ businesses, debts and future investment needs would be combined. Beinsure says no merger has been completed and the proposal remains under consideration.

AI infrastructure, Starlink expansion and government business

The article says the Texas result may also affect Musk’s AI infrastructure plans. It reports that governor-elect Hinojosa has supported a temporary pause on new data center construction while the state reviews effects on electricity infrastructure, water resources and household utility bills. Beinsure says this reflects broader political resistance to rapid AI infrastructure growth. The article adds that new restrictions could slow construction, raise compliance costs and make it harder to secure power for large computing facilities. It says restrictions on standard data centers would not automatically affect Tesla’s vehicle production or SpaceX’s launch business, though they could influence future AI-related investments and partnerships.

Beinsure also reports that the broader technology market reacted unevenly. Amazon, Alphabet and Microsoft rose as investors considered whether tighter data center rules could reduce capital spending and improve free cash flow, while companies more tied to new AI facility construction came under pressure.

SpaceX separately announced a commercial step on Wednesday, with Qualcomm Technologies confirming an agreement to provide infrastructure for Starlink Mobile’s planned nationwide cellular network. Beinsure says Qualcomm will supply cellular hardware, baseband processing technology and software for terrestrial 5G base stations under a multiyear agreement. The article says the deal would help SpaceX extend Starlink beyond satellite broadband into a combined satellite and terrestrial wireless service that could eventually compete with AT&T, Verizon and T-Mobile. It also says that move would bring added regulatory requirements tied to spectrum, infrastructure and competition. Beinsure notes that the election results do not block the Qualcomm agreement, but greater congressional attention to Musk’s businesses could affect the political environment around it.

The article says SpaceX’s government business is another area likely to draw attention. It provides launch services, satellite communications and other capabilities to NASA, the Department of Defense and other federal agencies. Beinsure says that as Starlink and other SpaceX technologies have become more important to communications and national security infrastructure, lawmakers have raised more questions about Musk’s role in government operations and possible conflicts of interest. Senator Edward Markey, according to the article, indicated that technology executives could face extensive congressional investigations after the election. Beinsure adds that such inquiries could examine procurement, contracting procedures and the relationship between Musk’s political activity and his companies, though increased oversight would not necessarily lead to contract cancellations.

What investors may watch next

Beinsure says the immediate stock drop reflects political and regulatory uncertainty rather than a confirmed decline in either company’s operations. For Tesla, investors will still be watching vehicle demand, margins, autonomous driving progress and the possible financial effects of a merger with SpaceX. For SpaceX, the article says the risks include Starlink investment, launch economics, government contracts and the company’s push into wireless telecommunications. The unresolved merger proposal adds another layer of uncertainty because its valuation, timing and structure have not been set.

According to Beinsure, the next few weeks will likely hinge on whether Democratic lawmakers begin investigations into Musk’s federal contracts, government relationships or proposed transactions; whether the incoming administration moves ahead with data center restrictions or other technology policies; and whether Tesla and SpaceX issue a formal merger proposal with valuation, shareholder terms and financing details. The article says Musk’s election spending was meant to preserve a political climate favorable to his companies, especially in Texas, but the result instead strengthened lawmakers who have raised concerns about his political influence and business activities. Beinsure concludes that investors are now reassessing those risks even as the wider U.S. market rallies.
