Yields Surge to 2002 Highs as Fear Deepens
Benchmark 10-year Treasury yields surged above 5.33% overnight to reach their highest levels since 2002, pushing the CNN Fear & Greed Index down to 31 as stock futures struggle.

Cerebras Sinks 8.9% on OpenAI Nvidia Shift
Cerebras Systems (CBRS) dropped 8.87% to $177.65 after reports revealed OpenAI's GPT-6.1 Sol Ultrafast is running on Nvidia hardware rather than Cerebras chips, compounded by a 19.4 million-share lockup unlock.
