Tech giants lose $2 trillion in SpaceX’s IPO month: ‘The valuations were unsustainable’

Key Points:

• In June 2026, the Magnificent Seven tech giants (Nvidia, Apple, Microsoft, Alphabet, Meta, Amazon, and Tesla) experienced a 10% market value drop, losing $2.3 trillion in market capitalization, coinciding with SpaceX's record-breaking $75 billion IPO valued at $2.1 trillion.
• Investor skepticism about artificial intelligence (AI) growth prospects has increased, with concerns that current valuations of AI-related firms unrealistically assume accelerating revenue growth; this has prompted a sector rotation from hyperscalers to chip manufacturers like Nvidia.
• Chip and memory manufacturers have seen extraordinary stock gains in 2026, with SanDisk up 760%, Intel tripling, and SK Hynix rising 300%, driven by sustained high demand and expected memory shortages through 2028.
• Technology giants are making unprecedented capital expenditures in data centers, with commitments exceeding $1 trillion by 2029, ensuring strong chip demand, though profitability of AI investments remains uncertain amid evolving market dynamics.
• Experts advise portfolio diversification away from volatile AI stocks toward more defensive sectors within the AI ecosystem and other structural themes, as rising interest rates and geopolitical tensions have tempered the previously favorable conditions for tech stock valuations.
