I don’t think twitter has $30B in valuation left. Musk bought it for $44B (which was beyond its value at the time, but okay). Since his takeover, it’s lost between 50-60% of its value. That was as of several months ago, so I have to imagine it’s even less now.
With the loss of brand equity, they might be sliding towards the single digit billions very quickly.
He’s just setting money on fire at this point.
