Is the AI Bubble Bursting?
Big tech lost over $2 trillion in October, and on Friday Intel had its worst day ever. WhatsApp is full of "it's 2000 all over again" forwards. A curious young learner brings the rumours, and a wise mentor who lived through the dot-com crash sorts myth from fact.

THE HYPEWhat actually happened
Black Friday for tech
Friday 30 October Amazon says it will spend even more on AI next year. Intel warns it will burn cash.
CRASH!The Nasdaq hit its lowest level in nearly three months.
One day's damage
Intel's fall was its steepest one-day drop on record.
Wiped off the Nasdaq 100 in October alone, down more than 5.8% for the month.
The world's biggest shopping spree
2026 spending on AI data centres ($ billion)
Both Amazon and Alphabet say 2027 will be even bigger.
J.P. Morgan's estimate of global AI spending in 2026 alone. It sees $5.5 trillion by 2030.
ZappySo the market is scared because they're spending too much?
Prof. BoltScared of how long it takes to earn it back. Spending is certain. Profits are a promise.
THE FACTSFive forwards, checked
"AI makes no money"
AI is just hype. Nobody is actually earning from it.
Microsoft's cloud business, Azure, grew 48% in the JulyβSeptember quarter, and it expects 49β50% next quarter. Azure crossed $100 billion a year for the first time. Its Copilot AI assistant has 30 million+ paid seats.
Some companies are clearly earning. The worry is that revenue is growing slower than the spending bill.
"It's 2000 all over again"
This is exactly the dot-com bubble. Everything will crash 80%.
In 2000β02 the Nasdaq fell about 78%, because many dot-com companies had no profits at all. Today's big spenders are some of the most profitable companies on earth. But they're now borrowing to spend: Meta plans to raise $97.5 billion.
Prof. BoltIn 2000, the companies were weak and the idea was strong. Today the companies are strong and the price is the question. Different disease, similar fever.
"AI is over"
The selloff means companies are giving up on AI.
The opposite. Amazon's CEO told shareholders to expect it to "spend meaningfully more in 2027". Alphabet said the same. Morgan Stanley expects AI infrastructure spending to pass $1 trillion next year.
Investors aren't selling because AI is dying. They're selling because it's getting more expensive.
"This is America's problem"
A US tech crash doesn't touch Indian investors.
Indians hold US tech through mutual funds. The Mirae Asset NYSE FANG+ fund was up about 21% in 3 months, India's top performer. Friday's fall will show up in its NAV this week.
If one of your SIPs is a US tech fund, last quarter's star may be this quarter's biggest drop.
VERDICT: MYTH"Bad for Indian IT"
An AI selloff is always bad news for TCS, Infosys and Wipro.
It's more twisted. Indian IT is hurt by AI succeeding, since it shrinks their outsourcing work. In late July, a global AI selloff actually sent Nifty IT up nearly 3% in a day, because Indian IT has little AI hardware exposure.
Weight of the five big IT firms in the Nifty 50: the lowest since at least 2002.
VERDICT: MYTHThe rate twist nobody forwards
The US Fed raised rates in September for the first time since 2023, then held at 3.75β4.00% on 28 October.
ZappyWhat do interest rates have to do with AI?
Prof. BoltAI profits are mostly in the future. When a safe bank deposit pays more, a promise of profit in 2030 is worth less today. Higher rates hurt "jam tomorrow" stocks the most.
Watch rates as closely as earnings. They decide how much the market pays for the future.
THE DEEP DIVEThe research behind the headlines
The $3 trillion hole
The basic maths A data centre is like a new hospital. You borrow to build it, the machines wear out, and you need enough patients every year to pay for it all, plus a profit.
Rule of thumb from Sequoia's David Cahn, who has tracked this gap since 2023.
The gap keeps growing
Cahn's estimate: the hole grew about 15 times in three years.
One real example
Microsoft's AI revenue (about $37 bn) against its 2026 spending plan (about $190 bn), as of April 2026. The best-placed company is earning back roughly a fifth so far.
A fund manager's check (Janus Henderson, 26 Oct 2026)
They reverse-engineered how much AI revenue is needed for a "normal" return (15% on capital, 30% profit margin). Their bottom-up revenue forecast falls short in all 12 years they modelled. But if companies accept a 10% return, or squeeze margins to 40%, the numbers work.
Prof. BoltSo it's not "AI can never pay". It's "AI pays only if profits are fatter or investors are more patient than usual." That's a thin rope to walk on.
2000 vs today, side by side
| Measure | Dot-com peak (2000) | AI boom (2026) | Worse now? |
|---|---|---|---|
| S&P 500 price vs next year's profit (forward P/E) | ~24.4x | ~22x (Jan 2026) | Slightly better |
| Tech sector price vs profit | ~60x | Far lower | Better |
| Star stock: Cisco then, Nvidia now (forward P/E) | ~107x | ~19x (May 2026) | Much better |
| Share of the index in the top 7 companies | ~15β17.5% | 35%+ | Much worse |
| Profits of the leaders | Many had none | Mag 7 earnings +30% (2025, first 9 months) vs +6% for the other 493 | Better |
| Funded by | Stock sales and telecom debt | Cash flow, now plus record bonds | Getting worse |
ZappySo prices are calmer than 2000, but the market is way more lopsided?
Prof. BoltExactly. In 2000 the price tags were crazy. Today the eggs are all in one basket. If seven companies sneeze, an S&P 500 index fund catches a cold.
If you own a US index fund or a "global" fund, about a third of your money may sit in just seven companies. Check the fund factsheet.
Running on borrowed money
Spending is now faster than cash coming in, so Big Tech is borrowing like never before.
- Oct 2025: Meta sells $30 bn of bonds, the biggest such sale ever.
- Jun 2026: Nvidia borrows $25 bn, its first bond in five years.
- Jul 2026: Amazon's $25 bn sale has to offer extra interest to attract buyers.
- Alphabet even sold a 100-year bond.
J.P. Morgan's forecast for tech-sector bond sales in 2026, with about $317 bn from the cloud giants alone.
IOU!The circle problem
Ratings agency Moody's has warned that a handful of AI labs make up a large share of the cloud giants' order books, and that these "circular" deals add concentration risk.
Prof. BoltBorrowing isn't wrong. But when your customer is also your investee, and the chips you borrow against are old in four or five years, lenders start asking harder questions. That's exactly what the bond market began doing this summer.
History's rule: builders vs users
Railway mania, Britain, 1846
Parliament approved 263 new railway companies in one year, for about 9,500 miles of track. Many investors were ruined. Later, about a fifth of US railway mileage went into receivership. The railways still built the modern world.
The fibre bubble, 1996β2001
US telecom firms spent over $500 bn, mostly on bandwidth. In 2001, only about 2.6% of the fibre laid was actually in use. By 2002, 23 telecom companies had gone bankrupt.
The twist
The "dark fibre" was later bought cheap by companies like Google, and became the backbone of search, streaming and the cloud.
The technology usually wins. The people who paid to build it often don't.
ZappySo which part of AI is today's "dark fibre"?
Prof. BoltNot the chips. They go out of date in a few years, so leftover chips are worth little. The lasting leftovers will be power plants, grid lines and buildings. Whoever buys those cheap after a crash may be the real winner.
The electricity bill, and India's chance
World data-centre power use (IEA)
By 2030, more than all of Japan uses today. AI's own share is expected to triple.
India's gap
India creates about a fifth of the world's data but has only about 3% of its data-centre capacity.
India's build-out (Wood Mackenzie)
AI-dedicated capacity: 275 MW to about 6,500 MW. The government says AI data centres could add 26.3 GW to power demand by FY32.
Even if AI stocks fall, India's data-centre, power and grid build-out has years of demand behind it. That's where the "picks and shovels" are, including Karnataka's planned green data centres.
THE VERDICTProf. Bolt's opinion, and what to do
Bubble or not? (Prof. Bolt's opinion)
The good ending. AI revenue catches up with spending over 2β3 years, like Microsoft's cloud is showing. This dip becomes a buying chance people later wish they'd taken.
The likely ending. Real technology, overheated prices. Stocks swing hard for a year or two as each earnings season tests the spending, then the winners separate from the losers.
The bad ending. Borrowed money keeps funding data centres that don't pay off, rates stay high, and a 2000-style 40β60% fall hits the most expensive names.
Prof. BoltMy view: AI is like the railways and the internet. The technology changes the world, and plenty of investors still lose money on the way. Both can be true at once.
So what should Zappy do?
With money
- Check how much of your money is in US tech or AI-themed funds. Keep it a slice, not the meal.
- Don't stop SIPs because of one scary week.
- Don't pile into "AI funds" or NFOs because of the hype either.
With forwards
- "It's crashing 80%!" and "It's going to the moon!" are both forwards, not facts.
- Ask: is the company earning, or only spending?
With your career
Whatever happens to AI stocks, AI tools are already in every office. Learning to use them well is the safest bet on the board.
Fridge-door cheat sheet
What happened
- Nasdaq 100: β5.8% in October, $2 trillion+ gone.
- Intel β29% in a day, its worst ever.
- Trigger: AI spending rising faster than AI profits.
Myth vs fact
- "No money in AI": mostly myth (Azure +48%).
- "It's 2000 again": half true.
- "AI is over": myth, spending is rising.
- "Not India's problem": myth, check your US funds.
Deep dive
- $1.5T AI spend in 2026 needs ~$3T of sales (Sequoia).
- Prices calmer than 2000; concentration far worse (35%+ in 7 stocks).
- Big Tech now borrowing heavily; "circular" deals flagged by Moody's.
- History: the tech wins, the builders often lose.
- India: 12 GW of data centres by 2030 = real long-term demand.
Your move
- Keep AI/US tech a slice, not the meal.
- Keep SIPs running; skip hype NFOs.
- Watch earnings and interest rates.
- Learn the tools, whatever the stocks do.
