SEC watching AI companies' disclosures after Nasdaq's worst month since March 2025

The SEC is examining what artificial intelligence companies tell investors, enforcement director David Woodcock told Reuters on Friday, amid worries that the AI boom was inflated by deals in which the same companies fund each other. Where accurate disclosure doesn't happen, 'enforcement will be present,' he said, as the Nasdaq capped its worst month since March 2025.

What happened

The Securities and Exchange Commission is examining artificial intelligence companies' corporate disclosures, its enforcement director, David Woodcock, told Reuters in an interview Friday. Reuters said the review comes as investor worries mount over a possible AI bubble that may have been fueled by 'circular deals,' arrangements in which chipmakers, cloud companies and AI labs invest in or lend to each other and then buy from each other. 'Our principal concern is that people are making accurate disclosures about material information so that investors know what they're getting into,' Woodcock said. 'Enforcement is a very necessary piece of making sure people are doing that.' Where such disclosure does not happen, 'then enforcement will be present,' he said.

Why it matters

Millions of Americans own the big AI spenders through 401(k)s and index funds. The Nasdaq composite fell 2.9% Friday, its worst day since June, and ended October with its worst month since March 2025, about 7.8% below its closing high, Reuters reported. Reuters estimated that more than $2 trillion in value was set to be wiped from the Nasdaq 100 in October. Hyperscalers, the giant cloud companies, made up more than a third of S&P 500 capital spending over the past 12 months, Capital Economics told Reuters.

More context

What he did not say: Woodcock did not name any company, and Reuters did not report any new investigation or case. Watching disclosures is not an accusation of wrongdoing. Woodcock, who became the SEC's enforcement director in May, said the agency does not want to stand in the way of tech innovation, but that its job is to make sure companies give investors the full picture on risks.

The week that set this up: On Thursday, Alphabet had its biggest one-day percentage drop on record, Reuters reported. Meta is weighing a record $97.5 billion stock raise to pay for AI expansion, according to Reuters. On Friday, Intel and Reddit each fell about 29% and Sandisk fell 13%, Reuters reported. Also Friday, the Financial Times reported, citing unnamed sources, that OpenAI cut its funding-round target by $10 billion to about $20 billion, according to CNBC. And The Information reported, with Bloomberg later corroborating, that Nvidia is in talks to guarantee debt for Nscale's West Virginia data center being built for Anthropic, TechCrunch reported. That deal is not signed.

Beyond AI companies: Woodcock said AI and the race toward superintelligence make scams easier and cheaper to run at scale, and that brokers need processes to protect retail investors. He said the SEC's asset-management enforcement unit is focused on conflicts of interest and valuations in private markets, adding, 'I think you'll see more activity in this space.' On prediction markets such as Polymarket and Kalshi, he said the SEC is working with the Commodity Futures Trading Commission: 'We want to be involved where it makes sense, but not in a way that crushes innovation.'

The strongest case for closer scrutiny: Investors have little way to judge AI spending if companies don't clearly explain who is paying for data centers and who carries the risk. A debt guarantee, like the one Nvidia is reportedly discussing, generally means the guarantor must pay if the borrower can't, the kind of exposure shareholders would want spelled out.

The strongest case for a light touch: Woodcock himself said the SEC does not want to stand in the way of innovation, and not every AI giant sank this month: Microsoft and SpaceX broke from the gloom, Reuters reported. JPMorgan expects global AI capital spending of about $900 billion in 2026 and $5.5 trillion by 2030, according to Reuters, a sign that big banks still see long-term demand. Disclosure rules already require companies to report material risks, so the question is whether they are being followed, not whether new rules are needed.

What's still unknown: Whether the SEC opens any formal inquiry into a specific AI company or deal; whether OpenAI's round closes and at what size; and whether Nvidia signs the Nscale guarantee.

Editorial sourcing notes

Woodcock's comments come from a Reuters interview published Oct. 30. No specific company, investigation or case was named. The $2 trillion Nasdaq 100 figure is a Reuters estimate made before October's final close. The OpenAI funding cut and Nvidia-Nscale talks are reports citing unnamed sources and have not been confirmed by the companies. The photos are file images, not from this week. Not investment advice.
