Shares of technology companies rose even as antitrust pressures looked set to build. Federal and state antitrust authorities are preparing to file new lawsuits against Facebook and Alphabet's Google in addition to a suit previously filed against Google.
Separately, Facebook said it would buy Kustomer, a startup that specializes in customer-service platforms and chatbots, part of an effort by the social-media giant to help companies use its platforms to do business.
Food-delivery app DoorDash said it plans to sell 33 million shares priced between $75 and $85 apiece, in an initial public offering that could give it a valuation of as much as $32 billion.
Shares of electric-truck maker Nikola plunged after reports that automaker General Motors would no longer take an equity stake in the company under a stripped-down agreement revealed Monday.
GM nixed plans to take an 11% stake in Nikola after a controversial period during which the electric-truck maker's founder was accused of making fraudulent claims about the company.
