Tesla and SpaceX Face $456 Billion Market Wipeout After 2026 Midterm Results

Tesla Inc. and SpaceX saw a combined market capitalization loss of approximately $456 billion in the two trading sessions following the 2026 midterm elections. The sharp decline, which concluded on November 5, followed a series of political shifts in Texas and Washington D.C. that analysts suggest could alter the regulatory landscape for Elon Musk’s primary ventures.

Tesla (TSLA) shares fell 14% over the two-day period, ending the November 5 session near $342. SpaceX, which transitioned to a public company in June 2026 under the ticker SPCX with an IPO price of $135, also faced significant selling pressure. According to Dow Jones Market Data, the combined wipeout reflects investor concern over the erosion of Musk’s political influence following a reported $474 million personal expenditure on midterm candidates.

Political Shifts in Texas and Regulatory Headwinds

The election results were particularly impactful in Texas, the operational home of both Giga Texas and the SpaceX Starbase. Musk-backed incumbents Governor Greg Abbott and Attorney General Ken Paxton were unseated by Democratic challengers James Talarico and Gina Hinojosa. These shifts are expected to end the highly favorable local regulatory environment that helped facilitate the rapid expansion of Musk’s aerospace and automotive facilities in the state.

Broader Market Volatility

The decline in Musk’s holdings occurred alongside a broader market downturn. Because Tesla and SpaceX are increasingly viewed as proxies for AI and autonomous technology, they were disproportionately affected by a sector-wide revaluation. Reports from Quartz indicate that the intersection of political losses and the cooling AI trade accelerated the selloff, as shareholders moved to de-risk portfolios in a newly uncertain legislative climate.
