AI Bubble or New Normal? Hyperscaler Credit Fears and Crowded Trades Rattle Equities

If you thought the AI trade was running out of road, you might want to check your rearview mirror, because the traffic jam is only getting worse. The S&P 500’s relentless ascent in 2026 has been powered by a handful of hyperscalers, their share prices levitating on the promise of AI-fueled capex and a future that looks, at least on paper, like a repeat of the late 1990s. But under the hood, cracks are forming. Credit default swaps on the biggest AI names are quietly ticking higher, and the crowding in AI-linked equities is so intense you can practically hear the FOMO humming through the wires.

The latest Seeking Alpha dispatch, published June 1, 2026, flags a surge in credit protection costs for the AI titans. The rally, it says, is 'heavily driven by AI-linked companies, with investor positioning increasingly crowded and FOMO palpable.' That’s not just anecdotal. The cost to insure against default for the largest hyperscalers has jumped to multi-year highs, even as their stocks continue to melt higher. It’s a market that looks unstoppable, until it isn’t.

Let’s talk numbers. The iShares Russell 2000 ETF ($IWM) is flat at $287.39, a yawning zero percent move that tells you all you need to know about market breadth. The global ACWI ETF ($ACWI) is equally comatose at $158.86. The AI trade, meanwhile, is still the only game in town, but the price of admission is rising. According to the latest data, AI megacaps now account for over 40% of S&P 500 gains year-to-date. Credit spreads for these names are up 20-30 basis points in the last month alone, a sign that bond investors are quietly hedging against a reversal while equity traders are still chasing the dream.

What’s driving this divergence? Part of it is the sheer scale of AI capex. The hyperscalers are spending tens of billions on data centers, chips, and power infrastructure, betting that every dollar poured into AI will come back with friends. But as the Seeking Alpha piece notes, 'AI capex projections have become self-reinforcing,' with each new spending announcement fueling another leg higher in both stocks and expectations. The market has seen this movie before, and it usually ends with someone left holding the bag.

The historical echoes are impossible to ignore. The 1999 analog is everywhere, parabolic price action, breathless media coverage, and a sense that missing out is more dangerous than overpaying. But there are key differences. Today’s AI giants are real businesses, with actual cash flows and fortress balance sheets. The problem is that the market is pricing them like perpetual growth machines, immune to competition, regulation, or the laws of financial gravity. That’s a high bar to clear, even for companies that have made a habit of clearing high bars.

Meanwhile, the rest of the market is stuck in neutral. Small caps, cyclicals, and anything not stamped 'AI' is languishing. The $IWM’s flatline is a symptom of a market that’s become dangerously narrow, with all the risk concentrated in a handful of names. If the AI trade unwinds, there’s not much of a safety net underneath.

The credit market is flashing yellow. Rising CDS spreads on the hyperscalers are a classic late-cycle tell. When bond investors start to hedge, it usually means they see something equity traders don’t, or can’t afford to care about. The last time we saw this kind of divergence was in the run-up to the dot-com bust, when credit got nervous well before stocks cracked. That doesn’t mean a crash is imminent, but it does mean the risk-reward calculus is shifting.

The macro backdrop isn’t helping. U.S. factory activity is expanding, construction spending is up, and the economic data is coming in hot. That should be good for stocks, but it also means the Fed is less likely to ride to the rescue if things go sideways. Inflation is still lurking, and the central bank’s patience is not infinite. If the AI bubble pops, there may be no soft landing this time.

Strykr Watch

Technically, the AI trade is still intact. The big names are holding above key moving averages, and momentum remains strong. But there are signs of fatigue. The $IWM is stuck below resistance at $290, and the $ACWI is unable to break out above $160. Breadth indicators are deteriorating, with fewer stocks making new highs even as the indices grind higher. RSI readings on the hyperscalers are flashing overbought, and volume is thinning out, a classic setup for a reversal if sentiment turns.

Options markets are starting to price in more volatility, with skew rising on both the upside and downside. That suggests traders are hedging their bets, buying protection against a sudden move in either direction. If the AI leaders break below their 50-day moving averages, it could trigger a cascade of selling as crowded trades unwind.

On the credit side, keep an eye on CDS spreads for the top AI names. If they continue to widen, it’s a sign that the smart money is getting nervous. A blowout in credit could be the canary in the coal mine for an equity correction.

The biggest risk is a disorderly unwind of the AI trade. If sentiment shifts, there’s not much liquidity on the way down. The crowding is extreme, and forced selling could turn a correction into a rout. Regulatory risk is also lurking, with antitrust scrutiny ramping up on both sides of the Atlantic. And if the Fed surprises with a hawkish pivot, all bets are off.

On the flip side, the opportunity is to fade the crowd. If you’re nimble, there’s money to be made betting against the most crowded names, especially if credit spreads keep rising. Alternatively, look for rotation into unloved sectors, small caps, value, and cyclicals, that could benefit if the AI bubble deflates.

Strykr Take

This is not your father’s dot-com bubble, but it rhymes. The AI trade has legs, but the risk-reward is getting stretched. Credit markets are flashing warning signs, and the crowding is reaching dangerous levels. If you’re long, tighten your stops. If you’re short, be patient, the unwind could be spectacular, but timing is everything. For everyone else, this is a market to trade, not to marry. The next move will be fast, and it won’t be forgiving.
