Google executive Donald Harrison resigns from SpaceX board; Musk cites conflicts of interest with Alphabet

SpaceX told the SEC on Friday, Nov. 6, that Donald Harrison, a Google executive, has resigned from its board of directors. He notified the company on Wednesday, Nov. 4, and the resignation took effect immediately.

Harrison served as a Class B Director of Space Exploration Technologies Corp. He has worked at Google since 2005 and is its president of global partnerships and corporate development.

What the filing says

The 8-K is short. It states that Harrison's decision "was not due to any disagreement with the Company on any matter relating to its operations, policies, or practices."

SpaceX thanked him for his "many contributions and his years of dedicated and outstanding service." The filing does not name a replacement.

It also does not give a reason beyond that. Musk supplied one on X.

"Don has been a great board member. Very much appreciate his contributions," Musk wrote. He added that there are too many conflicts of interest with Alphabet, Google's parent.

Why Alphabet's interests are so tangled with SpaceX

Alphabet is no minor party here. It put money into SpaceX in 2015, when the company was valued at about $12 billion. Alphabet is now SpaceX's largest institutional shareholder, according to LSEG data.

Alphabet reported Friday that it holds about 555 million shares, up slightly from 551.2 million. That stake was worth roughly $74 billion at Friday's close. SpaceX's market capitalization was about $1.8 trillion, about five months after its IPO, which CNBC described as the largest on record.

Google is also a customer. It has agreed to pay SpaceX's AI division up to $920 million a month for compute capacity at data centers around Memphis, Tennessee.

The two companies are also working together on Project Suncatcher, which puts Google AI chips into orbit on satellites built with Planet Labs.

One person sat on SpaceX's board while his employer was its biggest institutional investor, a major customer, and a technology partner. Musk's stated reason is a plain description of that arrangement. The filing discloses no wrongdoing, and no investigation or complaint has been announced.

Google says nothing changes

Google moved quickly to say the partnership is intact. "While Don is stepping down from the board, we remain deeply supportive of SpaceX's mission and are excited to continue our long-standing partnership," the company said in an emailed statement.

The share count backs that up. Alphabet reported an increased position, not a reduced one.

That is the strongest argument against reading the exit as a falling out. SpaceX's filing rules out a disagreement over operations, policies or practices. Google says it is staying. Musk's own explanation points to the structure of the relationship, not to a dispute with Harrison.

What a public company owes its shareholders

SpaceX is now a listed company, trading under the ticker SPCX. That raises the stakes on related-party dealings.

A contract worth up to $920 million a month between a public company and its largest institutional holder is exactly the kind of arrangement that shareholders expect to be reviewed by directors with no stake on the other side. Neither SpaceX nor Alphabet has said how the compute agreement was approved, or whether Harrison took part in any board discussion of it.

The filing does not address the point either way. It is a question for the next proxy statement and for SpaceX's governance disclosures.

What remains open

SpaceX has not said whether it will fill the Class B seat, or who might take it. It has also not said whether Alphabet will seek another board representative.

Musk's post was cut short in some reproductions, but the sentence as quoted ties the exit to conflicts with Alphabet. SpaceX's next filings will show whether the board seat is refilled and whether Alphabet's presence on the board returns in another form.
