Nvidia’s market cap plunged by nearly $600 billion, the largest single-day loss in U.S. history, as its stock fell 17% to $118.58. The drop was triggered by competition from China’s DeepSeek, which unveiled a cost-effective AI model. Concerns over declining GPU demand also impacted Broadcom, Dell, and Oracle. Analysts believe AI growth will boost compute demand long-term. Nvidia CEO Jensen Huang’s net worth dropped by $21 billion. DeepSeek’s app surpassed ChatGPT as the most-downloaded in the U.S., escalating the global AI race.

The U.S. Department of the Interior has officially renamed the Gulf of Mexico to the Gulf of America, acknowledging the shared coastline between Mexico and the U.S. Google Maps will adopt this new name, but in Mexico, it will remain the Gulf of Mexico.

This decision follows other name changes, such as the renaming of Denali (formerly Mount McKinley), and reflects the evolving dynamics of geographic naming in the region.

During a conversation aboard Air Force One, Trump hinted at this possibility, citing Saudi Arabia’s agreement to purchase billions of dollars in U.S. goods. Saudi Arabia has also expressed interest in investing $60 billion in the U.S. during Trump’s second term.

In a recent post, Musk invited “hardcore software engineers” to join his team, emphasizing coding talent over academic credentials or past employers.

TikTok resumed operations in the U.S. hours after shutting down, following President-elect Trump’s pledge to delay enforcement of a law banning the app. Trump promised an executive order to secure TikTok’s future, allowing its 170 million U.S. users to regain access. ByteDance, TikTok’s parent company, is exploring solutions, including a joint venture with U.S. ownership. Despite relief, the app’s long-term future remains uncertain due to bipartisan national security concerns and challenges in resolving ownership issues.

TikTok ceased operations in the U.S. Saturday night, hours before a nationwide ban took effect, citing a law requiring its sale to a U.S. entity. The Supreme Court upheld the ban, triggering app store removals and server restrictions. However, TikTok hinted at a swift return, noting President-elect Trump’s potential 90-day extension. The blackout leaves 170 million U.S. users and businesses in limbo, with bipartisan concerns over data security driving the ongoing controversy. Trump’s inauguration may determine TikTok’s fate.

Elon Musk may need to pay $40–$50 billion to acquire TikTok’s U.S. operations, similar to the $44 billion he spent on Twitter, analyst Dan Ives suggests. Reports indicate China might consider a sale to Musk to avert a U.S. ban over security concerns. TikTok’s parent, ByteDance, faces pressure to divest its U.S. assets. While TikTok dismisses the rumors, Musk’s strong ties with China and his social media ambitions position him as a potential buyer for this “golden asset.”
