#e4mXplains:  AI's trillion-dollar spill and what it means for Indian advertising

Last week, Wall Street was examining Big Tech's quarterly results and discovering, with considerable displeasure, that building the future is an expensive business.

This week, American voters decided they might have some opinions about that future too.

The combination has not been particularly kind to technology stocks.

On November 5, in the US, the Nasdaq Composite plunged 5.5%, its worst single-day fall in 19 months, while the sell-off erased approximately $3 trillion from S&P 500 companies. The panic promptly crossed the Pacific. By Friday's close and the setting sun, Japan's Nikkei and South Korea's Kospi had each fallen around 6%, while Taiwan's Taiex lost 4.5%. South Korea even briefly halted trading after losses exceeded 8%, roughly.

Investors, having spent years enthusiastically financing the AI revolution, suddenly seem rather interested in its electricity bills.

First came the earnings

As we examined previously, Alphabet's third-quarter results was basically a miscrocosm, a growing tension between the profitability of established technology businesses and the enormous cost of their AI ambitions.

Alphabet generated $127.58 billion in quarterly revenue, including $82.01 billion from advertising. It also spent $51.36 billion on capital expenditure, producing negative free cash flow of $9.07 billion.

Its shares fell 12.6% after the results.

Meta, Microsoft and Amazon offered variations on the same theme: strong businesses, extraordinary infrastructure commitments and investors increasingly unwilling to accept that tomorrow's profits will necessarily justify today's expenditure.

The problem was never that AI had stopped being impressive. It was that being impressive was becoming extraordinarily expensive.

And shareholders, rather inconveniently, expect to be paid eventually.

Then came the voters

The Democrats' sweeping victories in the November 3 US midterm elections introduced a fresh complication.

Data centres have become political battlegrounds over electricity consumption, water usage, environmental concerns and rising utility bills. Democratic gains raised investor concerns about tougher scrutiny and restrictions on infrastructure development.

This matters because AI's expansion depends on precisely the infrastructure now attracting political opposition.

Technology companies can promise extraordinary computational capabilities. They cannot, unfortunately, negotiate with the laws of physics, when it comes to generating vast hordes of electricity. 

Or as it turns out, with local planning authorities, and incoming government ones that are more inclined to ask more questions about water and said electricity.

The implications travelled quickly to Asia, where semiconductor manufacturers, chipmakers and equipment suppliers are deeply exposed to the American AI infrastructure boom.

The market correction therefore reflects two overlapping anxieties: whether AI investments will deliver sufficient returns, and whether companies can build the infrastructure needed to generate those returns in the first place.

India, meanwhile, declined to panic

While global markets were busy discovering new shades of red, Indian equities apparently went shopping. It was, after all, Dhanteras.

On November 6, the Sensex rose 2.17%, while the Nifty gained 2.01%, supported by foreign investment inflows, falling crude oil prices and relatively limited exposure to the capital-intensive AI infrastructure trade. Apparently being more consumer than producer does offer some comforts.

India's stock market appears, for the moment, to be benefiting from precisely what made it less fashionable during the AI rally.

But financial insulation is not commercial isolation.

India's advertising economy remains closely connected to the global technology companies whose valuations are under pressure.

According to Datum Intelligence, just India's festive advertising expenditure is expected to reach ₹60,000–62,000 crore in 2026, with digital commanding nearly 68% of the spending. Commerce and retail media alone are expected to attract ₹11,500 crore, growing 27% year-on-year.

Clearly, Indian advertisers remain rather enthusiastic about digital, even as Wall Street develops a sudden interest in what all this technology actually costs. 

Meanwhile, technology companies are not merely collecting advertising revenue. They are increasingly spending it.

Google was the largest advertiser across both linear television and connected TV during IPL 2026, accounting for 11% and 13% of advertising volumes respectively, according to TAM Sports. Its devotion to print and the festive opportunities of Search that could be found therein was also something to behold.

AI, it turns out, needs traditional advertising too.

Does this mean marketing budgets will shrink?

Not necessarily. And this distinction is rather important.

Google and Meta continue to generate enormous advertising revenues. Their financial problem is not a sudden collapse in advertiser demand, but the mounting cost of building businesses beyond their established commercial models.

A prolonged correction could make AI companies more selective about marketing expenditure, particularly those relying heavily on investor funding to acquire customers.

Equally, it could encourage larger platforms to monetise AI more aggressively.

There is also the possibility that AI's financial reckoning makes marketing technology buyers less enthusiastic about expensive promises and more interested in measurable results.

AI tools that demonstrably reduce production costs, improve targeting or generate sales should remain attractive. Those whose principal achievement is making an impressive presentation considerably more impressive may face harder questions.

None of this establishes that Indian advertising budgets are about to contract. Consumer demand, domestic economic conditions and actual campaign performance will remain more immediate determinants of expenditure.

But the terms of the AI conversation are changing. Until recently, the industry was largely concerned with what artificial intelligence could do.

Now investors want to know what it costs, governments want to know where it will get its electricity, and businesses increasingly want to know what they are getting for their money.
