Grocery delivery app Instacart makes IPO filing public

Grocery delivery app Instacart on Friday revealed a 31% jump in revenue for the first half of the year as it made public its filing for a stock market flotation in New York, setting the stage for one of the most anticipated listings in recent years.

The development comes 15 months after Instacart submitted its IPO paperwork confidentially, a move that is typically a precursor to an imminent listing.
