Investment bankers are telling Tesla CEO Elon Musk that he could fund his acquisition of Twitter via a "stock swap" or by exchanging $43 billion worth of Tesla shares for Twitter shares.

This is according to a Tweet by New York Post columnist and Fox Business Network contributor Charles Gasparino: "Investment bankers crunching numbers on how@elonmusk can finance a takeover of @Twitter have come up with this scenario: Do a stock swap, exchanging $43B-plus of his $TSLA shares for $TWTR shares since the investor base is similar (growth) and its a non taxable event."

On Thursday, April 14, Musk, speaking at a TED Talks event in Vancouver, British Columbia, was asked if he had a Plan B for purchasing the social media giant. Musk repsonded that he would tackle that question another day.

Twitter is considering a poison pill to block Elon Musk, a 9.2% shareholder, from significantly increasing his stake to purchase the social media platform, a source tells The Wall Street Journal.
