What happened

Anthropic's $2 trillion IPO roadshow slipped to mid-October on Thursday after Holtec Nuclear and Bamboo Insurance both pulled their US offerings as 30-year Treasury yields hit 5.44%, a 22-year high. Holtec had aimed to raise up to $900 million at $15-$18 per share but withdrew September 16 after investor appetite for AI-linked power stocks collapsed. CVC-backed Bamboo Insurance scrapped a $700 million deal on September 22, dropping a $3.24 billion valuation target for its home-insurance business. Both withdrawals push Anthropic's roadshow into a window shadowed by midterm elections and 64% odds of another Fed rate hike.

Why it matters

The IPO pipeline is the main route for private companies and early investors to cash out, so two big deals falling apart in one week signals a market growing much more selective about new listings. When 30-year government bonds pay 5.44% risk-free, investors demand steeper discounts on any new stock, squeezing growth companies that need premium valuations. For Anthropic, trying to nearly double its valuation from $965 billion to $2 trillion, every week of delay narrows the window before US elections.
