But digging deeper, the "people in the know" are now pointing out that this $1 Billion escape clause is actually very restrictive and unlikely to be invoked. Musk might be forced into buying Twitter at the previously negotiated $54.20 price.
But there's also the question: will Twitter's board really go to court to force Musk to buy it at $54.20? There's also the question of politics here. Even if Twitter's board is in the legal-right to do so, forcing Musk to become the new owner is bad politics.

There's also the possibility of the Twitter Board's incompetence. Maybe they don't realize the advantageous position they're in and give up before testing Musk in court?
