The cooling appetite for new listings stems from a combination of lukewarm demand and mounting anxiety over the sustainability of AI-sector pricing. Renaissance Capital analysts suggest that many issuers entered the market with expectations misaligned with a choppier reality. This correction is exacerbated by the 'pop and drop' phenomenon, where initial surges are met with aggressive sell-offs, leaving stocks like SpaceX’s down from their peak and Shanghai-listed Unitree Robotics tumbling 46.7 percent after its initial 460 percent spike.

Major players are recalibrating their timelines in response to this volatility. While Anthropic eyes a mid-November debut with a $2 trillion valuation target, OpenAI has deferred its plans until 2027. The caution extends beyond tech, affecting firms like Holtec and EG Group, which cite broader macroeconomic uncertainty and rising bond yields. In the UK, activity remains muted with only seven listings recorded in the first half of the year, though the upcoming £5.3bn debut of Airtel Money offers a rare point of optimism. Despite this, sentiment among money managers has soured significantly, with only 32 percent now anticipating a near-term recovery in market activity, down from 63 percent just six months ago.
