Markets on a Hair Trigger: Trump’s Tariff Whiplash and the AI Bubble That Won’t Pop

Markets move as Trump tweets

U.S. stock markets are behaving like a mood ring in a thunderstorm—volatile, reactive, and oddly sentimental.

One moment, President Trump threatens a ‘massive increase’ in tariffs on Chinese imports, and nearly $2 trillion in market value evaporates.

The next, he posts that: ‘all will be fine‘, and futures rebound overnight. It’s not just policy—it’s theatre, and Wall Street is watching every act with bated breath.

This hypersensitivity isn’t new, but it’s been amplified by the precarious state of global trade and the towering expectations placed on artificial intelligence.

Trump’s recent comments about China’s rare earth export controls triggered a sell-off that saw the Nasdaq drop 3.6% and the S&P 500 fall 2.7%—the worst single-day performance since April.

Tech stocks, especially those reliant on semiconductors and AI infrastructure, were hit hardest. Nvidia alone lost nearly 5%.

Why so fickle? Because the market’s current rally is built on a foundation of hope and hype. AI has been the engine driving valuations to record highs, with companies like OpenAI and Anthropic reaching eye-watering valuations despite uncertain profitability.

The IMF and Bank of England have both warned that we may be in stage three of a classic bubble cycle6. Circular investment deals—where AI startups use funding to buy chips from their investors—have raised eyebrows and comparisons to the dot-com era.

Yet, the bubble hasn’t burst. Not yet. The ‘Buffett Indicator‘ sits at a historic 220%, and the S&P 500 trades at 188% of U.S. GDP. These are not numbers grounded in sober fundamentals—they’re fuelled by speculative fervour and a fear of missing out (FOMO).

But unlike the dot-com crash, today’s AI surge is backed by real infrastructure: data centres, chip fabrication, and enterprise adoption. Whether that’s enough to justify the valuations remains to be seen.

In the meantime, markets remain twitchy. Trump’s tariff threats are more than political posturing—they’re economic tremors that ripple through supply chains and investor sentiment.

And with AI valuations stretched to breaking point, even a modest correction could trigger a cascade.

So yes, the market is fickle. But it’s not irrational—it’s just balancing on a knife’s edge between technological optimism and geopolitical anxiety.

One tweet can tip the scales.

Fickle!

AI Crash! Correction or pullback? Something is coming…

AI Bubble concerns

Influential figures and institutions are sounding the AI alarm—or at least raising eyebrows—about the frothy valuations and speculative fervour surrounding artificial intelligence.

Who’s Warning About the AI Bubble?

🏛️ Bank of England – Financial Policy Committee

  • View: Stark warning.
  • Quote: “The risk of a sharp market correction has increased.”
  • Why it matters: The BoE compares current AI stock valuations to the dotcom bubble, noting that the top five S&P 500 firms now command nearly 30% of market cap—the highest concentration in 50 years.

🏦 Jerome Powell – Chair, U.S. Federal Reserve

  • View: Cautiously sceptical.
  • Quote: Assets are “fairly highly valued.”
  • Why it matters: While not naming AI directly, Powell’s remarks echo broader concerns about tech valuations and investor exuberance.

🧮 Lisa Shalett – Chief Investment Officer, Morgan Stanley Wealth Management

  • View: Deeply concerned.
  • Quote: “This is not going to be pretty” if AI capital expenditure disappoints.
  • Why it matters: Shalett warns that 75% of S&P 500 returns are tied to AI hype, likening the moment to the “Cisco cliff” of the early 2000s.

🌍 Kristalina Georgieva – Managing Director, IMF

  • View: Watchful.
  • Quote: Financial conditions could “turn abruptly.”
  • Why it matters: Georgieva highlights the fragility of markets despite AI’s productivity promise, warning of sudden sentiment shifts.

🧨 Sam Altman – CEO, OpenAI

  • View: Self-aware caution.
  • Quote: “People will overinvest and lose money.”
  • Why it matters: Altman’s admission from inside the AI gold rush adds credibility to bubble concerns—even as his company fuels the hype.

📦 Jeff Bezos – Founder, Amazon

  • View: Bubble-aware.
  • Quote: Described the current environment as “kind of an industrial bubble.”
  • Why it matters: Bezos sees parallels with past tech manias, suggesting that infrastructure spending may be overextended.

🧠 Adam Slater – Lead Economist, Oxford Economics

  • View: Analytical.
  • Quote: “There are a few potential symptoms of a bubble.”
  • Why it matters: Slater points to stretched valuations and extreme optimism, noting that productivity projections vary wildly.

🏛️ Goldman Sachs – Investment Strategy Division

🧠 Julius Černiauskas and the Oxylabs AI/ML Advisory Board

🔍 View: The AI hype is nearing its peak—and may soon deflate.

  • Černiauskas warns that AI development is straining environmental resources and public trust. He’s pushing for responsible and sustainable AI practices, noting that transparency is lacking in how many models operate.
  • Ali Chaudhry, research fellow at UCL and founder of ResearchPal, adds that scaling laws are showing their limits. He predicts diminishing returns from simply making models bigger, and expects tightened regulations around generative AI in 2025.
  • Adi Andrei, cofounder of Technosophics, goes further: he believes the Gen AI bubble is on the verge of bursting, citing overinvestment and unmet expectations

🧠 Jamie Dimon on the AI Bubble

🔥 View: Sharply concerned—more than most as widely reported

  • Quote: “I’m far more worried than others about the prospects of a downturn.”
  • Context: Dimon believes AI stock valuations are “stretched” and compares the current surge to the dotcom bubble of the late 1990s.

📉 Key Warnings from Dimon

  • “Sharp correction” risk: He sees a real danger of a sudden market pullback, especially given how AI-related stocks have surged disproportionately—like AMD jumping 24% in a single day after an OpenAI deal.
  • “Most people involved won’t do well”: Dimon told the BBC that while AI will ultimately pay off—like cars and TVs did—many investors will lose money along the way.
  • “Governments are distracted”: He criticised policymakers for focusing on crypto and ignoring real security threats, saying: “We should be stockpiling bullets, guns and bombs”.
  • “AI will disrupt jobs and companies”: At a trade event in Dublin, he warned that AI’s ubiquity will shake up industries and employment across the board.

And so…

The AI boom of 2025 has ignited a speculative frenzy across global markets, with tech stocks soaring and investors piling into anything labelled “AI-adjacent.”

But beneath the euphoria, a chorus of high-profile warnings is growing louder. From the Bank of England and IMF to JPMorgan’s Jamie Dimon and OpenAI’s Sam Altman, concerns are mounting that valuations are dangerously stretched, capital is overconcentrated, and the narrative is outpacing reality.

Dimon likens the moment to the dotcom bubble, while Altman admits many will “lose money” chasing the hype. Analysts point to classic bubble signals: retail mania, corporate FOMO, and earnings divorced from fundamentals.

Even as AI’s long-term utility remains promising, the short-term exuberance may be setting the stage for a sharp correction.

Whether it’s a pullback or a full-blown crash, the mood is shifting—from uncritical optimism to wary anticipation.

The question now is not whether AI will change the world, but whether markets have priced in too much, too soon.

We have been warned!

The AI bubble will pop – it’s just a matter of when and not if.

Go lock up your investments!

Bulls and Bubbles: The stock market euphoria

Bubbles and Bulls

In the world of stock markets, few phenomena are as captivating—or as perilous—as bull runs and speculative bubbles.

Though often conflated, these two forces represent distinct psychological and financial dynamics that shape investor behaviour and market outcomes.

Bull Markets: Confidence with Momentum

A bull market is defined by sustained price increases across major indices. Typically driven by strong economic fundamentals, corporate earnings growth, and investor optimism.

In the U.S., iconic bull runs include the post-World War II expansion. The 1980s Reagan-era boom, and the tech-fuelled rally of the 2010s. The Dot-Com bull run, and subsequesnt crash is probably the most famous.

Bull markets feed on confidence: low interest rates, rising employment, and technological innovation often act as catalysts. Investors pile in, believing the upward trajectory will continue—sometimes for years.

But even bulls can lose their footing. When valuations stretch beyond reasonable earnings expectations, the line between bullish enthusiasm and irrational exuberance begins to blur.

Bubbles: Euphoria Untethered from Reality

A bubble occurs when asset prices inflate far beyond their intrinsic value. This is fuelled not by fundamentals but by speculation and herd mentality.

The dot-com bubble of the late 1990s is a textbook example. Companies with no profits—or even products—saw their valuations soar simply for having ‘.com’ in their name.

Similarly, the U.S. housing bubble of the mid-2000s was driven by easy credit and the belief that property prices could only go up.

Bubbles often follow a predictable arc: stealth accumulation, media attention, public enthusiasm, and finally, a euphoric peak.

When reality sets in—be it through disappointing earnings, regulatory shifts, or macroeconomic shocks—the bubble bursts! Leaving behind financial wreckage and a trail of disillusioned investors.

Spotting the Difference

While bull markets can be healthy and sustainable, bubbles are inherently unstable. The key distinction lies in valuation discipline.

Bulls are supported by earnings and growth; bubbles are driven by hype and fear of missing out (FOMO).

Tools like the cyclically adjusted price-to-earnings (CAPE) ratio and historical trend analysis can help investors discern whether they’re riding a bull or inflating a bubble.

📉 The Aftermath and Opportunity Ironically, the collapse of a bubble often sows the seeds for the next bull market. As excesses are purged and valuations reset, long-term investors find opportunities in the rubble.

The challenge lies in resisting the emotional extremes—greed during the rise, panic during the fall—and maintaining a clear-eyed view of value.

In markets, as in life, not every rise is rational, and not every fall is fatal

As of October 2025, many analysts argue that the U.S. stock market is exhibiting classic signs of a bubble. Valuations stretched across major indices and speculative behaviour intensifying—particularly in mega-cap tech stocks and passive index funds.

The S&P 500 recently hit record highs despite a backdrop of political gridlock and a government shutdown. This suggests a disconnect between price momentum and underlying economic risks.

Indicators like Market Cap to Gross Value Added (GVA) and excessive investor sentiment point to a speculative mania. Some experts are calling it the largest asset bubble in U.S. history.

While a full-blown crash hasn’t materialised yet, the market’s frothy conditions and historical October volatility have many bracing for a potential correction.

Are We in an AI ‘Super Cycle’? Some investors say Yes—and it could last two decades?

AI

The term ‘AI super cycle’ is gaining traction among top investors, and for good reason.

According to recent commentary from leading venture capitalists, we may be entering a prolonged period of exponential growth in artificial intelligence—one that could reshape industries, economies, and even the nature of work itself.

Unlike previous tech booms, this cycle isn’t driven by a single breakthrough. Instead, it’s the convergence of multiple forces: unprecedented computing power, vast datasets, and increasingly sophisticated models.

From generative AI tools that write code and craft marketing copy, to autonomous systems revolutionising logistics and healthcare, the pace of innovation is staggering.

What makes this cycle ‘super’ isn’t just the technology—it’s the scale of adoption. AI is no longer confined to Silicon Valley labs or niche enterprise solutions.

It’s being embedded into everyday workflows, consumer apps, and national infrastructure. Governments are racing to regulate it, while companies scramble to integrate it before competitors do.

Some analysts believe this cycle could last 20 years, echoing the longevity of the internet era. But unlike the dot-com bubble, AI’s utility is already tangible.

Productivity gains, cost reductions, and creative augmentation are being realised across sectors—from finance and pharmaceuticals to education and entertainment.

Still, the super cycle isn’t without risk. Ethical concerns, data privacy, and algorithmic bias remain unresolved. And as AI systems become more autonomous, questions of accountability and control grow sharper.

Some also suggest the market is ‘frothy’ (including the Fed) and is due a correction or at the very least a pullback.

Yet for now, the momentum is undeniable. Investors are pouring billions into AI startups, chipmakers are scaling up production, and global markets are recalibrating around this new frontier.

If this truly is a super cycle, it’s not just a moment—it’s a movement.

And we’re only at the beginning of the curve

Echoes of Dot-Com? Is AI tech leading us into another crash?

Is Wall Street AI tech in a bubble?

Wall Street is soaring on artificial intelligence optimism—but underneath the record-breaking highs lies a growing sense of déjà vu.

From stretched valuations and speculative fervour to market concentration reminiscent of the dot-com era, financial analysts and institutional veterans are asking: are we already inside a tech bubble?

Valuations Defying Gravity

At the heart of the rally are the so-called ‘Magnificent Seven’—mega-cap tech firms like Nvidia, Microsoft, Apple and Alphabet—whose forward price-to-earnings ratios have now surpassed even the frothiest moments of the 1999–2001 bubble.

Apollo Global strategist Torsten Slok has reportedly warned that current AI-driven valuations are more ‘stretched’ than ever, citing metrics that exceed dot-com records in both scale and speed.

Nvidia and Microsoft now sit atop the S&P 500 with a combined market cap north of $8 trillion. Yet much of this valuation is being driven by expected future profits—not current ones.

Bulls argue the fundamentals are stronger this time, but even they admit this rally is fragile and increasingly top-heavy.

A Narrow Rally, Broad Exposure

While the S&P 500 has reached historic highs, the gains are increasingly concentrated among just 10 companies—accounting for nearly 40% of the index’s value.

The remaining 490 firms are moving sideways, or not at all. Bank of America’s Michael Hartnett calls it the ‘biggest retail-led rally in history’, pointing to looser trading rules and margin exposure pulling everyday investors into risky tech plays.

In policy circles, reforms allowing private equity in retirement accounts and easing restrictions on day trading are amplifying volatility.

The Trump administration’s push to deregulate retail trading could worsen systemic fragility if investor sentiment turns.

Signs of Speculation

Meme stocks and penny shares are surging again. Cryptocurrency-adjacent firms are issuing AI-branded tokens.

Goldman Sachs indicators show speculative trading activity at levels only previously seen in 2000 and 2021. Yet merger activity remains robust, and consumer spending is strong—two counterweights that bulls cite as proof the rally may be sustained.

The Core Debate: Hype vs. Reality

Is AI the new internet—or just another tech bubble? It does seem to carry more utility than the early days of the internet did?

  • The Bubble View: Today’s valuations are divorced from earnings reality, driven by retail exuberance and algorithmic momentum rather than solid fundamentals.
  • The Bullish Case: Unlike the dot-com era, many of today’s tech firms are cash-rich, profitable, and genuinely transforming industry workflows.

Wells Fargo’s Chris Harvey reportedly believes the S&P 500 could hit 7,007 by year-end—driven by strong margins in tech and corporate earnings resilience.

But even he acknowledges risks if the AI hype fails to materialise into sustainable profit flows.

Bottom Line

Wall Street may be on the brink of another rebalancing moment. Whether this rally evolves into a crash, correction, pullback or a paradigm shift could depend on investor patience, regulatory restraint—and whether tech firms can actually deliver the future they’re pricing in.

That is the real question!
