Following the Democrats' victory in both chambers of the U.S. Congress, GLJ Research believes that a potential merger between SpaceX (SPCX) and Tesla (TSLA) will become slower, more costly, and less likely. For existing SpaceX shareholders, if the transaction originally required paying a high premium, a slower process could alleviate concerns about ceding too much equity, providing some support for valuations.

TradingKey - Elon Musk strongly backed Republican candidates in the 2026 U.S. midterm elections but failed to prevent the Democrats from taking control of Congress, leaving his companies facing fresh market pressure. Over the past two trading sessions, share prices of Tesla (TSLA) and SpaceX (SPCX) fell consecutively, resulting in a cumulative market capitalization loss of approximately $456 billion.

TradingKey - On November 5, Eastern Time, SpaceX (SPCX) shares fell 9.05% to close at $123.62, marking a second consecutive trading day of declines and retreating about 29.9% from its October intraday high of $176.42.

SpaceX's valuation plunged, tumbling 9% in a single day to approach its late-August low, with the market eyeing the key $100 psychological support level.

On November 5, Eastern Time, the three major U.S. stock indices tumbled, with semiconductor and AI infrastructure stocks continuing to face pressure. The Philadelphia Semiconductor Index fell over 9%, hitting its lowest level since mid-April this year. AI infrastructure faces the potential threat of a slowdown in data center construction. A decisive Democratic victory in the midterm elections sparked investor concerns over tightening regulation in the data center sector. If potential construction pauses materialize, they could delay the deployment of computing capacity and the delivery of upstream equipment, prompting a reassessment of the timeline for future revenue realization.

TradingKey - As of press time on November 4, Eastern Time, SpaceX (SPCX) fell over 7% in pre-market trading, currently trading at $130.64.
