Big investors are hedging the AI trade. Here's what that means for your portfolio
AI is having a monster year. Nvidia even sprinted past a $5 trillion market cap for a moment. Yet several well-known investors are dialing back exposure - or outright betting against the hottest names.
This isn't a verdict on the technology. It's a statement on price, debt, and discipline. If you manage money for yourself or others, that's the signal to pay attention to.
Who's trimming or shorting AI
- Bridgewater Associates cut large-cap AI and Big Tech positions, citing valuation risk.
- Tiger Global Management reduced exposure to major AI and mega-cap tech as part of broader de-risking.
- Tiger Cubs like Coatue, Lone Pine, Viking, and D1 pared back AI and Big Tech stakes.
- Michael Burry took on more than $1 billion in bearish put options against Nvidia and Palantir.
- Peter Thiel fully exited his Nvidia position.
- SoftBank sold roughly $5.8 billion of Nvidia stock to reallocate toward new bets, including OpenAI.
The core concern: debt-fueled infrastructure
"The fact that today's largest tech firms are raising debt at scale to fund AI infrastructure is a clear signal: we're in the middle of one of the biggest compute-buildouts in history," said Andrew Sobko, founder at Argentum, a marketplace for GPU capacity. "But with billions of dollars borrowed, investors have a right to ask: What happens if the demand curve stalls or the expected returns don't materialize?"
Pei-ju Lee at Bradley, Foster & Sargent points to hyperscalers ramping spend after back-to-back years of 60% growth. Capital expenditures could grow another 30% and top $500 billion in 2026, far above what was expected at the start of 2025. That spending once came from massive cash flow. Now, more of it is coming from borrowing.
In October alone, Meta and Oracle borrowed about $70 billion through bonds and loans. "Even more concerning is the use of the notorious off-balance sheet debt," Lee said. "Meta and Musk's xAI added almost $40 billion in debt in the past month. For those who remember Enron's epic collapse, the rise of off-balance sheet debt could be the canary in the coal mine."
Lee also flags systemic risk: AI-related investments are now a large share of U.S. GDP growth. "In particular, the majority of the spending hinges on OpenAI's whopping $1.4 trillion commitment. If OpenAI, which is not going to be profitable until 2029 at the earliest, can't secure funding and fails to make good on the commitment, the market is going to react very negatively. Then, the valuation of the high-flying AI arms dealers, like semiconductors and cloud infrastructure companies, is going to be significantly compressed."
'AI slop' is souring sentiment
The strongest AI players remain fundamentally sound. They're building real products and real revenue. The drag is the wave of low-quality "AI slop" - thin wrappers on existing models that add noise, not value.
"Too much funding is chasing incremental gains in model training, creating 'AI slop' that offers limited differentiation," said Shahrzad Rafati, founder and CEO of RHEI. "Sophisticated investors are right to be concerned about the divergence between sky-high valuations and the companies that actually demonstrate real tech, solving real problems, for real customers."
Rafati's read on Burry and Thiel: they aren't anti-AI. They're anti-hype. "They're reducing exposure to the broad market hype to protect against the AI slop," she said.
Will AI implode? Unlikely - but excess will be corrected
History rhymes. The dot-com vision was right; a lot of the pricing wasn't. Expect similar shakeouts as investors realize many ventures are little more than a thin layer on top of OpenAI APIs.
"Capital will become more discerning, flowing toward moonshots with substance rather than copycat plays," said Jason Hardy, CTO for AI at Hitachi Vantara. He expects robotics and physical AI to be the next visible step. "The bubble talk obscures the reality that AI's strongest players are building lasting value, and in the end, pragmatism will prevail."
What to do if you manage money
Ignore the daily drama and stick to first principles. "The debate over whether AI is a 'boom' or a 'bubble' is interesting, but in reality, it's a distraction to everyday investors focused on long-term wealth," said Alex Michalka, head of investments at Wealthfront. Market timing isn't a strategy - it's a guess.
Your best defense is a portfolio built to survive multiple futures.
- Diversify beyond a single theme. Spread risk across sectors, styles, asset classes, and geographies. The S&P 500 is diversified across companies, but AI weight is concentrated in the U.S. Consider non-U.S. equities and other assets. S&P 500 factsheet
- Right-size your tech/AI allocation. Cap single-theme exposure and rebalance on a schedule, not a headline.
- Use direct indexing if you need control. It tracks an index, can harvest taxes, and lets you exclude specific AI names if that helps you sleep. What is direct indexing?
- Stress test assumptions. Model scenarios where AI spend slows, credit tightens, or multiples compress. Plan your response before you need it.
- Keep liquidity. A cash buffer reduces forced selling when volatility spikes.
The bottom line
Big players hedging AI exposure isn't a prophecy - it's risk management. The buildout is real, but so are debt loads and pockets of "AI slop." Price, positioning, and cash flow still matter.
If you want thoughtful exposure, own durable businesses, diversify broadly, set rules, and stick to them. Your long-term result will come from discipline and time in the market - not guessing the next AI headline.
