McDonald's CEO Chris Kempczinski told analysts Thursday that the K-shaped economy, which splits consumer spending between the affluent and everyone else, may be getting worse. He described the macro environment and consumer sentiment as "certainly not improving, and it may be getting a little bit worse."

The divergence in spending patterns has been a persistent theme in retail earnings calls. Kempczinski noted that higher-income consumers show "very resilient spending," and McDonald's is seeing "solid growth" and gaining market share with that segment.

On the lower-income side, the picture is starkly different. While the CEO did not provide specific figures from the call, he indicated that these shoppers are cutting back further. He described overall consumer sentiment as marked by "heightened anxiety."

The implications for McDonald's are significant: the chain traditionally relies on value-conscious customers, making the lower-income pullback a strategic challenge. The company will need to balance efforts to retain affluent diners while defending its core base.

Kempczinski's remarks underscore a broader economic concern that the gap between haves and have-nots may be widening. Without a clearer recovery for lower earners, consumer-focused companies could face headwinds.
