Google executive Don Harrison resigned from the SpaceX board five months after the company’s record-breaking IPO. Alphabet remains the largest institutional shareholder with a $74 billion stake. The tech giant said, "We remain deeply supportive of SpaceX's mission and are excited to continue our long-standing partnership" regarding their future collaboration.

The announcement of Harrison's resignation comes just five months after SpaceX's landmark IPO, which was the largest on record.

Google parent company Alphabet has a long-standing relationship with SpaceX, having invested in Elon Musk's company back in 2015 when it was valued at about $12 billion.

Today, Alphabet is the largest institutional shareholder in SpaceX with a stake worth $74 billion as of Friday's close.

Despite Harrison's departure from the board, Google has reiterated its commitment to SpaceX's mission.

The tech giant said in an emailed statement, "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."

This comes as reassurance of their continued collaboration in projects such as Project Suncatcher.
