  • Amazon announced a $25 billion investment in Anthropic, complemented by Anthropic’s commitment to spend $100 billion on AWS over the next 10 years, solidifying a massive, long-term AI infrastructure partnership.

  • Shares fell 0.91% to $248.28 as investors scrutinise potential AI overspending and high valuations, despite the deal’s potential for significant long-term growth.

  • The underlying trend for Amazon (AMZN) remains bullish, with the price trading above key Simple Moving Averages (SMAs), although MACD and RSI indicators hint at overbought conditions.

Amazon announces $25 billion investment in Anthropic to strengthen AI infrastructure

According to reports from CNBC, Amazon has agreed to invest $25 billion in Anthropic to bolster its artificial intelligence (AI) infrastructure—an allocation that builds upon a prior investment commitment of $8 billion. Simultaneously, Anthropic has committed to spending around $100 billion on Amazon Web Services (AWS) technologies over the ensuing decade, seeking to enhance Anthropic’s capacity for training and deploying its Claude AI models.

While the announcement underscores a significant commitment to capital expenditure—primarily focused on AI infrastructure—it arrives amidst rising uncertainty regarding potential overspending and the implications of overvaluation that have affected sector-leading companies over the past year. In addition to the Anthropic partnership, Amazon has disclosed multi-billion-dollar investments in other entities developing AI services and infrastructure.

Consequently, although the investment suggests robust growth opportunities, Amazon’s share price dropped by 0.91% to $248.28, remaining very close to the company’s all-time record high.

Technical analysis of Amazon’s shares

Regarding the technical outlook, Amazon’s share price maintains its primary long-term bullish trajectory. Key observations include:

  • Trend Context: Over the long term, Amazon preserves a market structure defined by a sequence of ‘higher highs’ and ‘higher lows’. The price is currently trading above its 50, 100, and 200-day Simple Moving Averages (SMAs), reinforcing the prevailing bullish momentum as it hovers near record levels.
  • Resistance Levels: Should price action breach the immediate resistance at $254 (the current record high), the next significant technical level is identified at $270, representing the resistance ceiling of a bullish channel pattern. A decisive close above this level would likely initiate a new expansionary phase into uncharted valuation zones.
  • Support Levels: If the immediate support at $245 is invalidated, the next critical floor is located at $226, where the 100 and 200-day SMAs converge. A failure to defend the $226 level would substantially increase the probability of a more pronounced market correction.
  • Momentum and Volume: Both the Moving Average Convergence Divergence (MACD) and the Relative Strength Index (RSI) are currently trading near overbought territory, suggesting the possibility of a price contraction or a consolidation phase.
