I really get the feeling that the economy is being artificially propped up at the moment and the key event I suspect they're being propped up for is the midterm elections. Post election, I feel like the cracks will start to show and we'll start to get a correction which will lead to a crash, similar in size to 2008.
That's just my feeling and it isn't necessarily backed on too much but significant amounts of resources have been poured into "AI" and I really don't feel the payoffs are going to pan out. Once that becomes the mainstream view, everything built around it crumbles.
ChatGPT suggests one launch of starship could take that much cooling into space :
ISS cooling system (radiators): how many watts can it radiate? • The ISS External Active Thermal Control System (EATCS) (the big ammonia loops feeding the external radiators) is capable of rejecting up to ~70 kW total to space (≈ 70,000 watts). 
ISS radiators: how much does it weigh? • A single Heat Rejection Subsystem “Radiator ORU” (the deployable 8-panel radiator unit) is about 1,082–1,123 kg (≈ 2,380–2,475 lb) depending on the cited source/rounding.
How many kg can Elon’s Starship carry? • SpaceX’s current public spec is ~100–150 metric tons to orbit in a fully reusable configuration, i.e. ~100,000–150,000 kg (typically stated for LEO payload).
