A growing split in wages, spending, and sentiment reveals an expansion resting on uneven ground.

MARKET SIGNAL

The K-Shaped Economy Comes Into Focus

The economy is still growing, but not evenly. New data from the Federal Reserve, Bank of America, and consumer lenders show a widening split between high-income households pulling ahead and lower-income Americans losing momentum.

Wage growth for the top quarter of earners is running nearly a full percentage point above the bottom quarter. Delinquencies on subprime auto loans just hit a record. Nearly one-third of low-income households now live paycheck to paycheck.

At the same time, the stock market’s narrow leadership has concentrated wealth and confidence in the top 20 percent, who now account for more than one-third of all consumption.

The divergence has become large enough that policymakers have started naming it directly, even if they avoid the letter. The shape of the economy is changing, and the top line no longer tells the story.

The danger is not recession, but fragility. Growth depends increasingly on affluent households and the market value of the assets they own. When prosperity tilts toward the upper arm of the K, the whole expansion becomes hostage to confidence, sentiment, and a rally concentrated in a handful of stocks.

Imbalance at Inflection: The Return of the K-Shaped Economy

The U.S. economy is expanding, but the gains are flowing in sharply different directions. Wage growth for the highest-paid Americans is accelerating, while the bottom quarter of earners is falling behind. 

The gap is not new, but it is widening after several years of convergence in the aftermath of the pandemic.

Recent data from the Atlanta Fed show the top quartile earning wage gains of 4.6 percent annually, while the lowest quartile manages only 3.6 percent. 

On the surface, these are solid numbers. Underneath them is a growing imbalance between the consumers who drive demand and the consumers who increasingly cannot keep up with prices.

Credit markets reflect the strain. Subprime auto delinquencies reached 6.7 percent in October, the highest on record. Repossessions continue to rise. Bank of America data show nearly 30 percent of lower-income households living paycheck to paycheck. Middle-income families report that inflation is still outrunning take-home pay.

The imbalance is beginning to reshape the texture of demand. Spending by the top 20 percent remains strong, supported by rising wages, rising asset values, and the wealth effect from the AI-driven market surge. 

For the wealthiest 3 percent, the gains are even larger. Their spending now anchors the expansion, but their behavior is tightly linked to market performance.

This is where the K-shape matters. When earnings growth and spending capacity become concentrated at the top, the economy becomes more sensitive to asset prices. The expansion is no longer anchored in broad-based income but in a narrower, more volatile base.

The divergence is now visible in industry data. Consumer staples companies report shrinking volumes at the low end. Quick-service restaurants are seeing traffic declines among lower-income households. Auto dealers are facing reduced demand for new vehicles and rising defaults on used ones. 

At the same time, luxury brands, premium travel companies, and high-end services continue to outperform.

Confidence has split, too. High-income consumers report rising optimism. Low-income groups show the opposite. Economists have described this as a crisis of certainty and control for those at the bottom of the K. 

Losing ground in wages is compounded by higher shelter, utilities, and food costs. With little buffer, the sense of control evaporates first, and behavior follows.

For policymakers, the split complicates the picture. A softening labor market argues for continued rate cuts, while inflation that still exceeds target argues for patience. The Fed cannot target distributional inequality directly. But the K-shape makes inflation stickier for those least able to absorb it and makes growth more dependent on those most exposed to asset volatility.

The coming months will test whether the top half of the K can sustain the expansion as the bottom half strains. 

If high-income households remain confident and markets stay buoyant, growth can hold. If sentiment shifts in the asset-owning class, the imbalance becomes a risk factor of its own.

The shape of the economy is no longer linear. It bends. And that bend is becoming the most important signal in understanding where growth goes next.

Investor Signal

The economy can keep expanding from the top, but not forever. When spending becomes concentrated, volatility migrates from earnings reports to balance sheets, from wages to wealth.

Investors should expect heightened sensitivity to market drawdowns, ongoing stress in consumer credit, and stronger performance in sectors serving premium customers. The K-shape is not just a distributional issue. It is a stability issue.

RETIREMENT | Who Will Pay for the AI Buildout? Retirees

The AI boom is straining traditional funding channels. With data center capital needs reaching an estimated three trillion dollars through 2028, tech companies face a financing gap of roughly half that amount. Bond markets can absorb some of the load, but credit ratings limit how far hyperscalers can stretch their balance sheets.

Life insurers are emerging as the crucial link. A record wave of Americans turning sixty-five has pushed annuity sales to all-time highs, feeding an enormous pool of long-dated capital seeking reliable yield. These insurers are now among the largest marginal buyers in the credit markets, tightening spreads and expanding their appetite beyond plain vanilla bonds into more complex structures.

The match is structural. AI infrastructure demands long-duration capital. Retirement liabilities demand long-duration assets. Analysts expect hundreds of billions in new high-grade issuance tied to data center expansion over the next year. Insurers, motivated by demographics and longevity risk, are positioned to buy it.

For everyday investors, the shift introduces a new wrinkle. What once looked like a safe corner of the market may soon contain more exotic issuance tied to infrastructure with uncertain economics. The AI revolution may be funded by retirees, whether they realize it or not.

The Story Robinhood Users Aren’t Being Told

Robinhood’s had a monster year—stock’s up nearly 200% since January, and now the company just joined the S&P 500.

I’m talking about a market phenomenon that shows up almost every single day.

One that a handful of traders use to lock in steady payouts while everyone else chases noise. Most have no clue it even exists — but once you see how it works, you’ll never look at the close the same way again.

TECH | The New Question in AI: How Long Does a GPU Last?

Depreciation has become the quiet fault line in the AI trade. Hyperscalers are spending at unprecedented levels on GPUs, yet no one can say with confidence how long these chips will remain useful. Google, Microsoft, and Oracle estimate lifespans of up to six years. Critics argue the real number may be closer to two or three.

The pace of innovation is the wildcard. Nvidia is now releasing new chip generations annually, a shift that could compress the usable life of older architectures. Investors financing the buildout care deeply about these assumptions. A shorter lifespan reduces the years over which equipment can be depreciated, putting pressure on earnings and debt capacity.

Not everyone is worried. CoreWeave reports that older chips remain fully utilized, with expiring contracts immediately renewed at high rates. But short sellers, including Michael Burry, warn that companies are overstating useful life and understating depreciation expenses.

The tension reflects the reality of a three-year-old industry scaling faster than its accounting frameworks can keep up. Depreciation is no longer a footnote. It is a swing factor in the entire economics of AI.

PRIVATE EQUITY | Topgolf Nears Sale to Leonard Green

Topgolf Callaway Brands is in advanced talks to sell its Topgolf unit to private equity firm Leonard Green in a deal valuing the business at about one billion dollars. The sale would unwind a four-year merger that has struggled to live up to expectations as casual golfers pulled back on spending.

Topgolf’s model, built on recreational ranges and high-tech hitting bays, flourished during the early 2020s but lost traction as prices rose and discretionary budgets tightened for middle-income consumers. Callaway’s shares have fallen roughly sixty-five percent since the 2021 acquisition.

Leonard Green, already a minority investor, sees opportunity in repositioning the business for a more disciplined environment. The firm specializes in consumer and service-focused assets and has a track record of using operational resets to rebuild demand.

A sale would allow Callaway to separate its equipment business from an entertainment arm that no longer fits the company’s growth profile. For private equity, the deal offers a chance to buy a well-known brand at a steep discount and restructure it for a more divided consumer base.

THE PLAYBOOK

The K-shaped economy is more than a metaphor. It is a map of where growth now originates and where it no longer lives.

Affluent households, the asset-owning class, and the companies that serve them form the upper path of the expansion. Below it, stress accumulates in credit markets, consumer budgets, and essential spending.

Serious investors should watch not only wages and jobs, but confidence, sentiment, and the growing gap between financial stability at the top and financial fragility at the bottom. The bend in the economy is the signal. What breaks or accelerates from here will define the next stretch of this cycle.
