Americans bought 1,365,032 new vehicles in June 2026, up 7.7% from the same month a year earlier. But the people buying those cars look different than they used to. MarkLines

Here's what changed. The share of new-car buyers with household incomes under $100,000 fell from 50% in 2020 to 37% in 2025, according to CNBC, citing auto-industry data. That group had been stable for years, holding between 50% and 60% of new-car purchases before the drop began, as Reuters reported in March 2026.

The buyers left in the market are increasingly wealthy. In a Cox Automotive meeting transcript, Jamie Butters noted that new-car buyers tend to fall in the top 20% or top 25% of earners. Cox Automotive The wealthiest U.S. households own an average of 2.6 vehicles, compared with 1.0 for the poorest, per MarketWatch. In the most expensive U.S. zip codes, the skew is so pronounced that the Tesla Model S was the majority of car sales in eight of the 25 priciest zip codes, all in California, according to a MarketWatch analysis using registration data.

The industry's ability to charge high prices to these wealthy buyers showed up in profits. Ford raised its 2026 profit forecast to a range of $10 billion to $11 billion on July 28, 2026. Its adjusted earnings per share — a measure of profit divided among shareholders — came in at 42 cents, beating analysts' expectation of 35 cents, Reuters reported. Ford pointed to strong pricing and a resilient consumer.

The broader context here is that the "resilient consumer" Ford describes and the shrinking under-$100,000 buyer share are not contradictory. They are the same thing seen from two angles. Think of it like a restaurant that raises its prices and loses its budget-conscious customers, but the remaining diners are wealthy enough to keep ordering. Sales can go up even as the customer base shrinks, because the people still in the room can afford the bill. The 7.7% June increase is real. So is the fact that it's being delivered by a smaller and smaller slice of the population.

For automakers and their suppliers, the effects are concrete. They build more high-end versions of their cars. They advertise to a narrower group. They lend to people with strong credit, not weaker credit. The discounts and deals that used to pull in budget buyers during slow periods matter less when those buyers have already left the market. Ford's raised profit forecast and the broader sales growth fit a sector that has found a comfortable spot: higher prices, fewer customers.

The question is whether that comfortable spot lasts. The 13-percentage-point drop in the under-$100,000 share over five years, if it continues, would shrink the pool of potential new-car buyers well below what the industry's factories were built to serve. Used cars soak up the people priced out of new ones, but used-car sales don't fund the building of new factories. If the income needed to buy a new car keeps rising faster than what most people earn, the industry's ceiling on how many cars it can sell falls with it. June's 1.37 million units is a strong number. Who bought them is the harder problem.

For investors, Ford's profit beat is not just about one company doing well. It's about whether the high prices that produced that profit are here to stay or whether they'll eventually fall as even wealthy buyers finish upgrading and stop shopping. The income data through 2025 suggests the narrowing is still happening, not leveling off.

What the data doesn't yet tell us is whether the under-$100,000 share has stabilized in 2026 or kept falling. Ford's forecast suggests management expects the current pattern to hold through the rest of the year. The June sales figure confirms volume is growing. It does not confirm the buyer base has stopped shrinking.
