Fidelity's Timmer says AI bubble risk lies in debt, as CoreWeave bond yields top 15%

Fidelity's director of global macro, Jurrien Timmer, says any AI bubble may sit in debt markets rather than stocks. Yields on bonds from AI cloud provider CoreWeave topped 15% last week, even as equity valuations fall. Timmer compared CoreWeave's yield with a Bloomberg index of junk-rated telecom bonds from the 1998 to 2000 boom. In that era, the warning came from debt, not dot-com stocks. Highly rated AI borrowers still look stable, he said. CoreWeave's 2031 notes yielded 15.78% last Thursday. Its debt rose from $21 billion at the end of 2025 to $35 billion by June 30, and net interest expense of $640 million took about a quarter of second-quarter revenue. Chief executive officer Mike Intrator said its backlog, near $104 billion, more than covers its debt.

Veir raises $24.9M Series A+ for high-temperature superconductor power transmission

US startup Veir has raised $24.9 million in a Series A+ round. VXI Capital, Galvanize Climate Solutions, Fidelity Investments, Congruent Ventures, The Engine, and Breakthrough Energy Ventures invested. Veir develops a way to transmit electricity using high-temperature superconductors (HTS). Its platform uses evaporative cryogenic cooling. The technology lets utilities carry more power at lower voltage within a smaller right-of-way. This helps connect the lowest-cost renewable resources to the places that need them.
