Megacap Tech Declines Drag S&P 500 Amid AI Spending and Rate Concerns

Why it may matterVerify against the original reporting
A ~5% decline in two megacaps (Alphabet and Amazon) reduces S&P 500's tech-leaning cap exposure and can pull the index lower, especially if rates remain a concern and AI spending remains elevated. History shows mega-cap moves disproportionately drive intraday and multi-day SPX performance; similar slumps in 2020-2022 and 2023 often preceded broader tech weakness and delay in rebound. SpaceX's private-market signal adds noise but reinforces risk-off sentiment around growth funding.
