Wall Street’s cautious recovery dissipated fast as tech megacaps lost momentum, overshadowing cryptocurrencies’ rally after a tough December. Dollars and bonds stabilized.

While 300 shares fell, the S&P 500 was unchanged. A claim that OpenAI’s Sam Altman is shifting internal resources to develop ChatGPT, declaring a “code red” scenario that may delay other projects, prompted caution. Tesla led megacap losses as Michael Burry labeled the shares “ridiculously overvalued.”

S&P 500 near 6,820. Tesla fell 1.8%. Boeing Co. rose as it anticipated cash again in 2026.
