Airbnb takes new steps toward IPO

Departing American Express CEO Ken Chenault is joining Airbnb's board as its first independent member, the company said on Thursday. This comes just days after Chenault also agreed to join Facebook's board.

• In March, Airbnb plans to release its first annual stakeholder report.

Between the lines: Airbnb remains coy about its IPO plans, but it's hard not to see these as anything other than steps toward a public listing.
