The shutdown will halt about $8 billion a month in federal food assistance. Walmart captures 24% of all SNAP shopper spending, according to Numerator’s 2025 SNAP Evolution report—triple Kroger’s share and far ahead of Costco, Amazon and Sam’s Club.
Walmart was the first retailer to accept SNAP online in all 50 states in 2023 and launched the Walmart+ Assist program, which offers half-price memberships for those receiving aid.
“If SNAP payments stop, spending by the lowest income groups will fall,” said Neil Saunders, managing director of data and analytics firm GlobalData. “Walmart gets a plurality of the spending, so it will be hit the hardest.”
