There is plenty of evidence of growth. The problem is SpaceX as it is is a conglomerate recently cobbled together, and so estimating what it is and what it's going to do is challenging.
We don't have good public numbers, but that should be over $13B in revenue and about $2B of income over the last 12 months. Given the growth trend of that 5 years, that approx. $2B of income is likely to double by the end of this year.
Add to that the space launch business around Falcon 9, which had 40+ commercial launches that generated about $4B revenue and something close to $3B of income, and SpaceX was looking strong.
Again, SpaceX isn't what it was 6 months ago, before all the xAI fuckery, but the core business, Starlink and space launch, are doing well by themselves.
