New York: Donald Harrison, a senior Google executive and longtime member of SpaceX’s board of directors, has resigned from the Elon Musk-led aerospace and artificial intelligence company after more than a decade. His departure was disclosed on November 6, 2026, in a regulatory filing, following his decision to step down on November 4, one day after the US midterm elections.
Harrison’s resignation comes at a significant time for SpaceX, as the company considers its future business structure and a possible combination with Tesla. The timing has drawn attention because independent directors are reportedly examining a potential merger between the two companies.
SpaceX stated in its filing that Harrison’s decision was not connected to any disagreement with the company’s operations, policies or practices. However, Elon Musk separately referred to potential conflicts of interest involving Alphabet, Google’s parent company, in a public response to the development.
Donald Harrison steps down after more than a decade
Harrison informed SpaceX on November 4 that he intended to resign from its board with immediate effect. The company disclosed the development in a Form 8-K filing submitted to the US Securities and Exchange Commission on November 6.
Harrison served as a Class B director at SpaceX. He joined the board in 2015, when Google invested in the rocket, satellite and technology company.
During his association with SpaceX, Harrison remained an important link between the company and the wider technology and investment ecosystem. He is a longtime Google executive and currently serves as president of Global Partnerships and Corporate Development at Alphabet.
SpaceX acknowledged his contributions and years of service in its regulatory filing, thanking him for his work and wishing him well in his future endeavours.
The filing did not announce a replacement for Harrison or provide further details about the arrangements following his departure.
Elon Musk points to conflicts of interest
Although SpaceX’s official filing stated that Harrison did not resign because of disagreements over company policies or operations, Musk offered additional context in a public response.
Musk said Harrison had been a good board member and expressed appreciation for his contributions. He also indicated that there were too many conflicts of interest involving Alphabet.
The comment has drawn attention because Alphabet has a substantial financial interest in SpaceX. At the same time, Google and SpaceX operate in increasingly competitive areas of artificial intelligence.
Google develops its Gemini AI models, while Musk’s companies are developing Grok and expanding their AI-related activities. Both businesses are part of a rapidly evolving technology market in which competition extends across software, computing infrastructure and advanced AI systems.
The potential overlap between their business interests makes the issue of independent board oversight particularly important.
However, neither the regulatory filing nor the public comments establish that a specific dispute led to Harrison’s resignation. The company formally stated that his departure was not due to disagreement over its operations, policies or practices.
Alphabet remains a major SpaceX investor
Alphabet is one of SpaceX’s largest institutional shareholders. According to Reuters, Google reported an increase in its SpaceX holding to approximately 555 million shares from 551.2 million shares earlier.
The investment reflects Google’s long-standing relationship with SpaceX, which began when the technology company backed Musk’s venture in 2015.
SpaceX has since expanded beyond its original rocket-launch business. Its operations include satellite internet services through Starlink, commercial space launches and ambitious plans involving artificial intelligence and other advanced technologies.
Alphabet’s financial interest in SpaceX makes Harrison’s position particularly noteworthy. His role at Google involved corporate partnerships and development, while his SpaceX board membership placed him within the governance structure of a company in which Alphabet holds a significant investment.
The situation highlights the challenges that can arise when executives hold positions across businesses with overlapping interests. Board members are expected to exercise independent judgement and protect the interests of the companies they serve.
Harrison’s departure removes one such connection between the two organisations, although Alphabet continues to hold its investment in SpaceX.
SpaceX and Tesla merger discussions attract attention
Harrison’s resignation also comes as SpaceX and Tesla reportedly examine the possibility of a business combination.
Musk said last month that special committees of independent directors had been formed at both companies to consider a potential merger. Bloomberg reported that there was an effort to announce a possible deal in the first half of 2027, with the aim of completing it during the current US administration.
The possible combination could bring together two major parts of Musk’s business interests. Tesla is known for electric vehicles, battery technology and energy products, while SpaceX operates in aerospace, satellite communications and launch services.
A merger would represent a significant corporate development, potentially linking their technologies, resources and long-term business strategies.
However, no merger has been officially announced. The reported discussions should not be treated as confirmation that a deal will take place.
The departure of Harrison has attracted additional attention because he was among the directors considered independent at SpaceX. Other directors identified in reports include Ira Ehrenpreis, Roelof Botha, Luke Nosek, Steve Jurvetson and Randy Glein.
The composition and independence of the boards could be important if the companies move forward with any major transaction.
What Harrison’s departure means for SpaceX
Harrison’s resignation marks the end of a relationship that began during an important period in SpaceX’s growth. Google’s investment in 2015 came as the company was expanding its ambitions in commercial spaceflight and satellite-based internet services.
More than a decade later, SpaceX has become a major player in the global space industry and is also expanding its presence in artificial intelligence.
The departure does not, by itself, indicate a change in SpaceX’s business strategy or its relationship with Alphabet as an investor. The company has also not announced any replacement for Harrison in the available filing.
Nevertheless, the timing places the board change within a wider discussion about corporate governance, potential conflicts of interest and the future structure of Musk’s business empire.
For now, the confirmed development is that Donald Harrison has resigned with immediate effect. Whether the move has any wider implications for the reported SpaceX-Tesla discussions remains uncertain.
