Based on the most recent estimates of Twitter's value, Musk has already train wrecked 10s of billions of dollars.
You mention that Twitter isn't that fundamentally different and from a product perspective, and I would mostly agree, but their finances are WAY worse than they were pre-Musk. The company has lost something like 50% of ad revenue, they've saddled themselves with something like an extra $1B dollars a year in debt payments from the buyout, and they're facing a number of large lawsuits based on how they handled layoffs.
