The AI industry is hoovering up capital and transforming financial markets in the process. Mammoth listings from SpaceX, Anthropic and OpenAI could add as much as $4trn to the value of America’s listed firms by the end of the year. Existing AI stocks have already powered an enormous stock-market boom and the industry is issuing increasing amounts of debt. The euphoria is probably pushing up interest rates, too. But it remains unclear exactly how much and how quickly AI will transform the economy—and who will win and lose when it does. Financial risks are building as investors make huge bets on an uncertain future. If the technology realises its potential, will those bets pay off? If it doesn’t, what would the fallout look like? Henry Curr, Mike Bird and Josh Roberts, three of The Economist’s economics and markets experts, take stock of tech stocks and consider what could go wrong.

  • A booming stock market, enormous IPOs, debt-financed investment.

  • The artificial intelligence boom is driving everything in financial markets at the moment.

  • But change in the real economy has been slower,

  • and past tech booms have often brought about financial busts.

  • So will the AI mania end in vindication or despair?

  • I'm Henry Curr, and this is Inside Economics.

  • I'm delighted to be joined in the studio by Josh Roberts, our capital markets correspondent.

  • Hi, Josh.

  • Hi, Henry.

  • And down the line, as usual, we have Mike Bird in New York,

  • our Wall Street editor.

  • Hi, Mike.

  • Hey, Henry.

  • So we're going to look at three questions today.

  • One, how big is this mania?

  • Two, what do investors need to happen to justify what they're betting on?

  • And three, how might it all go wrong?

  • So let's start with the mania.

  • And I think a good place to start is the IPOs, because what we're seeing

  • in terms of AI IPOs this year is extraordinary.
