Tech & AI Daily — Wednesday, August 5, 2026

All four watchlist ETFs rose Wednesday — led by SOXL up 2.09% — as an AI-driven tech rally pushed indexes to record highs and Amazon crossed $3 trillion in market cap. • AMD's data center revenue doubled year-over-year to $6.7 billion, cementing its role as a genuine second-source rival to Nvidia in AI infrastructure spending. • Anthropic signed a $10 billion compute-cloud deal with startup Volta, one of the largest AI infrastructure commitments ever, as it moves to reduce dependency on AWS. • SpaceX's AI and compute division now generates $2.6 billion in revenue — more than its rocket business — making Elon Musk's company an unexpected heavyweight in AI infrastructure. • Nvidia, Microsoft, Meta, and roughly 25 other companies signed a coordinated letter demanding Washington keep open-weight AI models unrestricted, with Jensen Huang making his X debut to amplify the message.
