There's huge incentive.

The government has arbitrary commandeered their business.

This could ruin Anthropic.

They are walking a tight rope with respect to revenues, hype, IPO.

If this kills their hyper growth prospects, it could kill the IPO.

If there's a serious change the gov. is out of line, the judges could put a stay and possibly throw this out.

There may however be enough of a case, in which there's maybe not much they can do.

Having a crazy person completely control your business is very, very bad.

Maybe they would prefer Nationalization more than an IPO.
