To make money.

Edit: it's amazing that this earned me downvotes. It's demonstrably the objective to make a lot of money. They're going for IPO. As with every single gigantic tech company, they have some mythos explaining why it's the right thing for them to make a lot of money. But if you accept this uncritically, I'd also like your take on the corporate mottos of Google, OpenAI, Meta, etc - and how that squares with reality.
