Elon Musk is closing in on seizing Twitter as talks between the Tesla magnate and the tech giant entered their final stages, reports say. The billionaire could take over the company as soon as this morning as the board reportedly looked set to accept his offer of $54.20 per share. The tycoon's representatives were said to be hammering out terms including a timeline and fees if an agreement was signed and then fell apart. The two sides were reportedly working into the early morning to finalize the 'fluid and fast-moving' negotiations. Twitter shares soared by four per cent as the markets opened to $50.84 a share amid reports it would be seized by Musk. It comes a fortnight after the entrepreneur first sought to woo shareholders with his $54.20-per-share bid.
