It seems that Elon Musk might really be buying Twitter after all.

Sources say that the Twitter board met with Musk on Sunday to discuss the deal.

The deal might go through as early as this week.

However, it’s been reported that Twitter is open to considering other offers.

Musk offered $54.20 per share in text messages to the Twitter board chair.

Sources told Reuters Musk said $43 billion was his “best and final” offer.

Earlier this month, Musk said he wants to open source Twitter’s algorithm.

He has proposed changes like the highly controversial edit button.

He has also spoken about the importance of maintaining free speech on the platform.
