Alex Gibney’s Critical Musk Documentary Premieres Amid Tesla and SpaceX Merger Speculation

Musk disclosed that Tesla and SpaceX are jointly developing Terafab, a semiconductor-manufacturing facility, while also conducting shared research at Tesla’s Austin complex. SpaceX’s Grok systems and Tesla’s autonomous-driving AI were cited as additional areas of technological overlap.
Despite renewed merger speculation, early trading showed little market reaction: Tesla shares fell 0.1% and SpaceX shares rose 0.4%.
Gibney said the documentary expanded from an initially planned two-hour film to nearly four hours after Musk became closely involved with Donald Trump and US government affairs, including through the Department of Government Efficiency.
The documentary draws on accounts from people in Musk’s personal and professional life, including his father Errol Musk, former Tesla CEO Martin Eberhard and Ashley St. Clair, described as Musk’s former partner and the mother of one of his children.
Gibney said the film aims to encourage citizens worldwide to reclaim power from technology oligarchs, whom he described as appearing to want to run the world for themselves.
Elon Musk has reignited speculation about merging Tesla and SpaceX, citing deepening collaboration in semiconductors, artificial intelligence, and research. Kalshi puts the odds of a merger before 2028 at 66%, while analysts estimate Musk could receive an $824 billion stake in such a deal. Meanwhile, Alex Gibney's nearly four-hour documentary "Musk" premiered at the Venice Film Festival, examining Musk's rise through his companies, his political influence with Donald Trump, and his reliance on government support.
The film portrays Musk critically, questioning whether wealth and authority have corrupted him or revealed his character. Musk has denounced it as a false "hit piece," declined to participate, and threatened legal action. Despite merger speculation, Tesla shares fell 0.1% and SpaceX shares rose 0.4% in early trading.

Gibney stated that the documentary aims to encourage citizens worldwide to reclaim power from technology oligarchs, whom he described as appearing to want to run the world for themselves. The film examines Musk's government support and his outsized influence in shaping national policy. It portrays a complex figure—questioning whether his accomplishments reflect genius or whether wealth and authority have revealed troubling aspects of his character.
Musk declined to participate in the documentary and has denounced it as a false "hit piece," even threatening legal action against the filmmakers. His refusal to engage directly with Gibney contrasts sharply with his public merger announcements and social media statements. The documentary screens at Toronto after its Venice premiere, ensuring wider global distribution and audience reach for Gibney's critical examination of the Tesla and SpaceX founder.
