Musk's filing won't be the end of this, but it does mark the conclusion of high-stakes suspense over whether he would complete the deal, after a public spat with the company over the number of bots on the platform.

In recent weeks the company said that it had been sharing information with Musk in order to consummate the deal as laid out in the merger agreement, and reiterated their intention to close the transaction and enforce the agreement, the Wall Street Journal reports.

There are no guarantees Mr. Musk will be able to walk away from the deal entirely, as Twitter is expected to challenge his legal arguments. Deal clashes often end in negotiated settlements that can include a price cut or one-time payments.

Mr. Musk's lawyer cited concerns over Twitter's estimates about how many of its daily users are fake or spam accounts as an issue Mr. Musk raised as a concern about the deal almost three weeks after he signed it.

Discovery should be fun...
