The K-Shaped Summer

A year ago, most marketers weren't thinking about AI search. Now it's one of the fastest moving channels in the industry and nobody has a playbook yet.

So we built one. We surveyed hundreds of marketers to find out how they're approaching answer engine optimization, where they're investing, what's actually working, and what isn't.

The result is the 2026 State of AEO Report. Real data. Real strategies. A clear picture of where AI search is headed and how to get ahead of it.

Travel costs are running roughly 9 percent above year-ago levels. Memorial Day weekend travelers spent an average of nearly 900 dollars on the three-day window, per the most recent PwC consumer poll. Average U.S. gas prices have climbed back toward the upper end of their range on Middle East supply concerns. Airfare, hotel rates, restaurant tabs, and event tickets are all printing meaningfully above 2025 levels.

On the surface, that looks like a story about a broadly stretched consumer.

It is not. Look at the same data one layer deeper and a different story emerges. Roughly 49 percent of Gen Z and 43 percent of millennials planned to travel for Memorial Day. Lower-income households are far more likely to have no travel plans at all, with their travel-related card spending down year over year. Bank of America's recent consumer survey put the dropout rate near 40 percent for the bottom income segment. Higher-income households are absorbing the higher prices and traveling more, not less. Middle-income households are taking shorter trips, traveling closer to home, and spending less on accommodations.

The American consumer is not one consumer right now. It is two. The K-shape, which entered the lexicon during the pandemic recovery, has not gone away. It has hardened.

For the household, that has direct consequences for how you should run your cash, your credit, and your portfolio exposure through the rest of the summer.

What a K-Shaped Economy Looks Like Underneath the Headlines

Aggregate consumer-spending data hides the divergence. A headline number like spending up 2 percent year over year sounds like a single broad trend. The actual composition is closer to: spending up 6 percent at the top quartile, spending flat in the middle two quartiles, and spending down 3 percent at the bottom quartile. Average those together and you get the headline. The lived experience is nothing like the average.

Three structural forces are widening that gap.

First, asset prices and labor income have decoupled. A household that owns a home in a market that has appreciated 30 percent over five years, alongside an investment portfolio that has tripled since 2020, has experienced enormous balance-sheet expansion. A household renting in the same market, with no equity exposure, has experienced only the higher rents. Both households may have received similar pay raises. Their financial trajectories are not similar.

Second, interest rates cut both ways depending on which side of the balance sheet you sit on. A retiree with significant fixed-income holdings is earning more income on the same balance than at any point in the past fifteen years. A borrower carrying credit card debt is paying interest rates that have not been seen in a generation. The same policy stance is generous to one household and punishing to the other.

Third, inflation is uneven by category. Goods inflation has cooled substantially. Services inflation, particularly in housing, healthcare, and dining, has remained stickier. Households whose budgets are weighted toward services feel meaningfully higher inflation than the headline number implies. Households whose budgets are weighted toward goods feel meaningfully lower.

Fourth, the labor market itself has split. The unemployment rate at the headline level has stayed low. Underneath it, the job-finding rate for workers laid off in the past six months has slowed. Median time to find new employment is running noticeably longer than it did two years ago. For an employed household, the labor market still looks fine. For a household navigating a job transition, it has gotten harder. That difference compounds quickly. A six-week job search and a sixteen-week job search are two very different financial events.

The aggregate consumer is healthy. Many individual consumers are not. Both statements are true.

What This Means for Your Cash Position

Wherever you sit on the K, the cash side of your balance sheet needs more attention this summer than it usually gets.

For the upper-K household, the question is not whether to hold cash, it is whether your cash is earning its keep. The fed funds rate is in a 3.50 to 3.75 percent range. High-yield savings accounts and Treasury money market funds are paying close to that. Brokerage sweep accounts, by contrast, often pay a small fraction of that. Tens of thousands of dollars sitting in default sweep yield is one of the single largest unforced errors in the upper-K household balance sheet. Solving it takes one afternoon and produces meaningful annual income for as long as rates remain elevated.

For the middle-K household, the question is how much cash to hold. The traditional advice is three to six months of essential expenses. In a K-shaped, summer-volatility regime with sticky services inflation, the higher end of that range is the right end. Six months of essential expenses, held in a high-yield instrument that pays you while it sits there, is the financial equivalent of body armor against any combination of job-market softening, vehicle breakdown, or family emergency that summer might deliver.

For the lower-K household, the question is whether any cash is being built at all. The honest answer for many households in this bracket is no. The first dollar of emergency savings is harder to build than the thousandth. The right framework is not to target three months of expenses on day one. It is to set up an automatic weekly transfer of an amount small enough not to disrupt the budget, into a separate high-yield account, and then forget it. Twenty dollars a week is a thousand dollars a year, in an account paying real interest, that did not exist this morning. That is the entire game at this stage.

Credit: The Single Most Important Summer Decision

If you carry a balance on a variable-rate credit card, that balance is the most expensive money you will ever borrow. Average U.S. credit card rates are running north of 22 percent. That is not a slightly higher than typical rate. That is the highest sustained credit card rate environment in modern memory. Carrying a 5,000 dollar balance at 22 percent for a year costs roughly 1,100 dollars in interest, before any principal is paid down.

No investment strategy you can pursue with the same 5,000 dollars is going to outperform paying that balance off. The S&P 500's long-run real return is roughly 7 percent. Paying off a 22 percent credit card is a guaranteed 22 percent return, tax-free, with no risk. The math is not close. It is not even on the same continent.

Yet a meaningful portion of households across all three segments of the K continue to carry balances while also contributing to investment accounts. That sequencing is backwards. Pay the variable-rate consumer debt first. Build an emergency cash buffer second. Invest third. The order is not a moral judgment. It is the math.

There is one nuance worth noting. Employer retirement-match contributions are an exception to the sequence. If your employer matches 401(k) contributions up to a certain percentage of salary, capturing the full match is functionally a 50 percent or 100 percent immediate return, depending on the formula. That return outpaces even a 22 percent credit card payoff. Contribute enough to capture the full match, then route every additional discretionary dollar to the highest-rate debt until it is cleared. The math still holds. The carve-out for the employer match is the only exception worth making.

For the household that is over-extended on credit going into a summer of higher discretionary costs, the move now is not to grin and bear it through Labor Day. It is to call the card issuers and ask, in writing, for a rate reduction. Many will grant one to a customer with on-time payment history. It is to consolidate the highest-rate balances onto a single zero-percent introductory offer card and pay it aggressively before the promotional period ends. It is to pause discretionary travel for one summer in service of clearing the balance, then return to normal next year with no anchor attached.

Portfolio Implications of a Bifurcated Consumer

The K-shape shows up in earnings, and earnings show up in stock prices. Companies whose customer base skews to the upper-K segment have been printing stronger numbers. Luxury hotel chains, premium travel operators, high-end retail, wealth-management franchises, and the financial-services names with affluent client books have generally exceeded expectations through 2026 earnings season. Companies whose customer base skews to the lower-K segment have generally missed. Dollar stores, value-oriented restaurant chains, mid-tier apparel, and consumer-staples names with high private-label competition have struggled.

This is a portfolio-construction signal, not a market-timing call. If you are positioning equity exposure for a K-shaped consumer regime, you want the upper-end exposure overweighted relative to the lower-end exposure. That can be done directly through individual names, or indirectly through broad sector ETFs that happen to skew toward higher-end consumer franchises.

It also means caution around the names that look cheap on a price-to-earnings basis but are cheap because the customer base is genuinely cracking. A low multiple on declining earnings is not a value opportunity. It is a value trap. The discipline is to separate the two by reading the actual customer-cohort behavior in the earnings transcripts, not the multiple alone.

Tooling the Household Side

Three pieces of the household financial system make the summer easier to manage.

For the cash side, Empower aggregates checking, savings, and brokerage cash into one view, so you can see at a glance how much idle cash is sitting in low-yield sweeps versus working accounts. The visibility is the prerequisite for moving it.

For the investment side, M1 Finance lets you build an upper-K-tilted portfolio as a percentage-based allocation, set automatic contributions, and rebalance with one click. The automation removes the friction that causes most retail investors to drift away from their stated allocation.

For the automation that ties it all together, Make.com handles the recurring transfers, the alerts, and the weekly summary emails that turn a static plan into a system that runs whether you remember it or not.

The Four Months Ahead

June, July, August, and September will deliver a steady stream of earnings reports, inflation prints, FOMC meetings, and headline-driven volatility. The K-shape will not resolve itself between now and Labor Day. The households that use the next four months to tighten cash positioning, eliminate variable-rate debt, and align portfolio exposure with the regime they are actually in will end the summer in a structurally stronger position than they started.

The households that drift through summer responding to whichever headline is loudest will end September with the same balance sheet they have today, plus four months of foregone progress.

The difference is not skill. It is sequencing. Cash first, credit second, exposure third. Same order, every season.
