Hah. I have wondered about this particular one a fair bit.

First, it seems there is just not market for their product that could possibly support the valuation in the near future. Second, by virtue of already being so large a company, there is no room for evaluation of new small projects that would change direction. Anything must immediately have enough potential to generate millions in revenue.

Runway is maybe 5 years, so they got until then to produce enough revenue to raise more funding or become profitable. IIRC they sold approximately 50% of the company for the 500M round. Maybe I got this one completely wrong, but I just don't see how this can go well. What an incredibly inefficient allocation of capital for the ecosystem. Imagine giving 100 teams 5M each instead.
