US stock futures extend decline; Nasdaq futures down 1.5%, S&P 500 futures down 0.80%

The split in futures — Nasdaq down far more than the Dow — points to a tech-led de-risking rather than a uniform macro selloff, with the growth-heavy end of the market absorbing the pressure. That distinction matters for crypto and other risk assets, which have tended to trade alongside the Nasdaq rather than the broader index. Whether the weakness stays concentrated in high-multiple names or broadens into the Dow is the open question worth tracking.
