Tesla (NASDAQ: TSLA) and SpaceX are at the center of a merger discussion openly driven by Elon Musk at a moment that is anything but coincidental.
SpaceX filed its S-1 on May 20, 2026, targeting a $1.75 trillion valuation that would represent the largest initial public offering in human history.
Tesla currently trades at $441.72 with a market capitalization of roughly $1.66 trillion, meaning a combined entity would be worth approximately $3.4 trillion.
That combined valuation would be controlled by a single man who would, in that scenario, plausibly become the first trillionaire on the planet.
Musk has spent 2026 consolidating his business empire, with xAI folded into SpaceX and the operational entanglement between Tesla and SpaceX becoming increasingly difficult to ignore.
Tesla’s Q1 2026 filing disclosed a $2 billion equity investment in SpaceX, and the two companies are jointly building a semiconductor research fab at the Gigafactory Texas campus.
Musk has separately announced a “Terafab” plant in Austin targeting one terawatt of computing capacity per year, infrastructure that signals a shared roadmap between Tesla’s autonomy stack and SpaceX’s satellite compute ambitions.
Polymarket bettors currently place the odds of a merger announcement by June 30 at 4.6%, but odds of an announcement by May 1, 2027 sit at 52%, a number that has been rising.
SpaceX generated $18.7 billion in 2025 revenue, with Starlink contributing $11.4 billion, or 61% of the total, while Starlink subscribers reached 10.3 million by the end of Q1 2026, up from 5.0 million a year earlier.
The Connectivity segment posted $1.19 billion in Q1 segment operating income, and twenty-three banks are underwriting the IPO, led by Goldman Sachs (NYSE: GS).
Tesla’s Q1 2026 revenue came in at $22.39 billion, up 15.78% year over year, with automotive gross margin expanding to 21.1% from 16.2% and Full Self-Driving subscriptions hitting 1.28 million.
Tesla has also begun Cybercab production at a sub-$30,000 price point and is discontinuing the Model S and Model X to free manufacturing capacity for Optimus robots.
A combined entity would effectively be a robotaxi-and-rocket conglomerate with a humanoid robot business and a vertically integrated chip fabrication operation under one roof.
The governance mechanics of any potential merger carry significant consequences for Tesla shareholders, as SpaceX is going public as a controlled company with a dual-class share structure.
Per the SpaceX S-1, Class B shares carry ten votes each while Class A shares carry one vote, with Class B holders voting separately to elect 51% of the board.
Musk holds 42% equity in SpaceX but commands 85% voting power, meaning any merger structured as SpaceX acquiring Tesla would convert public Tesla holders into Class A stock with substantially reduced governance rights.
Tesla currently operates on a one-share-one-vote structure, with institutional ownership at 44.9% carrying real weight at the ballot box under the current arrangement.
The bull case for Tesla shareholders centers on gaining exposure to Starlink’s cash flow, SpaceX’s launch business, and xAI’s Grok platform alongside the existing automotive and energy operations.
The bear case involves governance dilution compounded by a forward price-to-earnings ratio that already sits at 215 times earnings and 175 times 2027 earnings estimates.
Analyst consensus on Tesla alone stands at a $411.89 price target, below the current trading price, and the Tesla investor relations page has not addressed merger mechanics.
