Nvidia stock jumps 4.3% to close at a record for the first time since Oct., pushing Nvidia's market cap past $5T, as a rally in Intel pushed chipmakers higher (Jordan Novet/CNBC)

Nvidia's market cap surpassed $5 trillion amid broader chipmaker strength, while simultaneously, DeepSeek released its V4 models demonstrating competitive AI capabilities with significantly lower computational costs and Huawei chip compatibility—signaling intensified geopolitical competition in AI infrastructure and potential disruption to GPU-dependent AI economics. For IT organizations, this dual development means evaluating alternative AI compute strategies and preparing for potential shifts in vendor lock-in dynamics as cost-efficient, open-source alternatives gain traction globally.
