State of play: Publix is the most popular grocery chain in Tampa Bay, with 38.5% of the market share as of last year.
Walmart is a solid runner-up, with 25.8% of the share, according to new data from Chain Store Guide, which tracks the retail and food service industries.
Flashback: Last year, Publix held 40% of the market while Walmart had a little more than 20%.
What's next: Amazon — which acquired Whole Foods in 2017 for $13.4 billion — is looking to dramatically expand the grocery wing of its commerce empire, Axios' Richard Collings and Kimberly Chin write.
A Whole Foods is under construction in St. Petersburg, off 38th Avenue North. It'll soon compete with two nearby Publix stores.
