On November 19, 2025, CNBC reported three significant market developments [1]:
- The S&P 500 index fell for its fourth consecutive trading day
- Bitcoin briefly dropped below the $90,000 threshold before rebounding
- Anthropic, an AI firm, signed a strategic deal with Microsoft (MSFT) and Nvidia (NVDA) valuing the company at approximately $350 billion
The S&P 500 extended its decline trend, closing down 0.36% on November 18 at 6,617.33 [0]. Over the past five trading days (Nov 12–18), the index recorded three down days: Nov12 (-0.25%), Nov13 (-1.30%), Nov17 (-0.61%), and Nov18 (-0.36%) [0]. This four-day decline signals a potential shift in broader market sentiment.
Bitcoin experienced extreme volatility on Nov18, dipping to a low of $89,391.9 [2] before rebounding to close at $93,591.8 (+1.52% for the day) [2]. CNBC highlighted ETF outflows and thinning liquidity as contributing factors, hinting at weak support levels [3].
Despite Anthropic’s $350 billion valuation deal with MSFT and NVDA [1], both public companies saw their stocks decline on Nov18:
- MSFT closed at $493.79 (-0.26%) [0]
- NVDA closed at $181.36 (-1.10%) [0]
This divergence between private AI firm valuations and public AI stock performance indicates potential investor caution toward public AI equities.
