Elon Musk on Thursday made his intentions with Twitter Inc. official, offering to buy the company at $54.20 per share in cash. So far, the social-media platform has said it would review his offer, which values the company at around $43 billion.

Speaking at a TED conference hours after making the offer, Mr. Musk said he isn’t sure he will actually be able to acquire Twitter, adding that his offer isn’t about the economics or making money. Asked if he had funding secured, Mr. Musk said, “I have sufficient assets.”
