Sainsbury’s recorded its biggest market share gain since 1997 in last quarter as Asda’s sales plummet.
According to fresh data from Kantar, Sainsbury’s market share jumped from 14.8% last year to 15.3% for the 12 weeks to 4 August, as it maintained its streak of being the fastest growing traditional supermarket. Its sales rose 5.2% over the period.
Meanwhile, Asda sales plunged 6%, as its market share fell from 13.7% to 12.6%, the market research firm reported.
Tesco maintained its streak of winning share every month since August 2023, with its hold of the market climbing to 27.6%.
Additionally, sales were up 11.3% at Ocado, as the online grocer continued its 6-month run as the fastest growing supermarket.
Across the wider market, grocery inflation rose to 1.8% from 1.6% last month, marking its first increase since March 2023.

Kantar head of retail and consumer insight Fraser McKevitt noted: “Having reached its lowest rate in almost three years in July, August saw inflation nudge up again slightly.
“While this is noticeable following 17 straight months of falling rates, it actually marks a return to the average levels seen in the five years before the start of the cost of living crisis.”
He added: “It is a mixed picture on supermarket shelves with prices now rising across 182 product categories, as the costs in 89 others fall.
“With this kind of pricing spread, shoppers will find that the type of product they’re putting in their baskets will really dictate how much they pay.”
