Elon Musk stunned markets when he tweeted Tuesday that he would seek to take his electric-auto company private in a deal worth billions of dollars, announcing he had “funding secured.” The move underscored the unpredictability of America’s most valuable car company — and Musk’s unconventional leadership style.

Tribune Media withdrew from its proposed merger with Sinclair Broadcast Group, ending an effort that would have created the biggest U.S. television company. Tribune also said it would sue Sinclair for $1 billion on grounds that the conservative television giant engaged in “misconduct” and precluded the U.S. government approving the deal. Tribune said it would terminate the $3.9 billion deal and accused Sinclair in a lawsuit of engaging in “belligerent and unnecessarily protracted negotiations” with the Federal Communications Commission as well as the Justice Department, which reviewed the merger over its potential effects on competition. Sinclair denied the charges.
