The AI IPO Wave Is Coming

SpaceX has filed for IPO. OpenAI and Anthropic are next. The biggest AI listings in history are about to hit US markets — together worth more than the entire FTSE 100. Most of the coverage frames this as confirmation that the AI boom keeps running. Neil Woodford's view is different: the trade may already be more concentrated than investors realise, and where the money flows from here is the question almost nobody is asking.

In this week's Noise Cancelling, Neil Woodford and Jon Adair break down what's actually inside your S&P 500 tracker, why your MSCI World fund holds the same AI trade, why the KOSPI has quietly become a Samsung and SK Hynix index, and how the cap-weighted index flywheel runs in both directions. They cover the S&P 500 inclusion rules that will keep OpenAI and SpaceX locked out of the index for years, the source-of-funds problem facing the $300 billion of new equity supply, and why Nvidia's record-beating earnings still couldn't lift the share price after hours.

Plus: how this is different from the dotcom bubble, what would change Neil's view, and where he thinks investor attention shifts next — beyond the AI providers, into the companies that deploy AI to transform their own margins.
