> I don't see Alphabet share price changing much just because of SpaceX being valued 2T instead of lets say 1T

Half of Alphabet's revenue increase last quarter came from marking up unrealized gains in their Anthropic investments.

I'm not saying Alphabet is doing this to juice the share price, but I want to point out that they don't have to sell shares to post banner earnings results and see a 10% jump in share price overnight.

That's a good point
