Elon Musk Says Twitter Deal Is ‘On Hold’

Elon Musk said his planned acquisition of Twitter was “temporarily on hold” because of concerns about fake accounts, a surprise twist that jolted investors and raised questions about his willingness to go through with the $44 billion transaction.

Mr. Musk’s grenade came in a tweet posted at 5:44 a.m. Eastern Time that was followed just over two hours later by another saying he was “still committed to acquisition.” The announcement was unorthodox not just in its timing and format, but because Mr. Musk referenced a recent Twitter disclosure about fake and spam accounts that it has made consistently for years—and because Mr. Musk has already signed an agreement for the purchase and waived detailed due diligence on the deal.
