US stocks just had their worst crash since the 2025 tariff shock. $3 trillion erased in 6 hours.

The trigger? Fear that Democrats might ban AI. Both stocks and crypto got hammered.

The numbers:
1. S&P 500 down 4.36%
2. Nasdaq down 6.36%
3. Chip stocks posted their worst drop since March 2020
4. $BTC fell 5.47%

Just yesterday markets were celebrating midterm results. Today everything reversed hard.

This is classic sentiment whiplash. Markets were pricing in one political outcome, then suddenly had to reprice regulatory risk around AI. The speed of the move shows how fragile positioning was — likely overleveraged longs got flushed out fast.

What's interesting: the AI regulatory fear hit tech hardest, but crypto followed. That correlation tells you $BTC is still trading as a risk asset, not a hedge. When liquidity tightens and fear spikes, everything correlated sells off together.

The chip stock carnage makes sense — if AI development faces regulatory headwinds, the entire semiconductor supply chain reprices. We haven't seen this kind of single-day tech washout since the COVID crash.

Watch for:
1. How quickly this fear gets walked back or confirmed
2. Whether this creates a buying opportunity or signals a deeper shift
3. Crypto's ability to decouple if macro stays ugly

Markets hate uncertainty more than bad news. Right now we're in maximum uncertainty mode.
