📉 Nasdaq 100 crashes 6.4% and S&P 500 sheds 4.4% as Democratic midterm sweep detonates AI regulation trade
Wall Street suffered its worst session in 18 months as the Democratic Party's decisive midterm sweep — including progressive mayoral wins in Los Angeles and New York — revived fears of AI data-centre moratoriums and tougher tech regulation. Nasdaq 100 -6.4% led the carnage, with tech the epicentre; S&P 500 -4.4% erased all midterm-night gains and then some. Retail traders dumped the most stocks in a single day since the Covid sell-off, per CNBC. The only isolated bright spot: Southern Company, which rose more than 1% during the sell-off after reporting a Q3 EPS beat and signalling a capital plan approaching $100B over 5 years — a data-centre demand confirmation in the middle of an AI-infrastructure panic.
Wall Street shed $3.2tn as newly elected progressive officials pledged curbs on data-centre construction, rattling the AI infrastructure trade (FT). Retail traders dumped stocks at the highest rate since the Covid sell-off (CNBC). The Nasdaq 100 -6.4% was the index's worst single-day decline in 18 months — tech hedge funds that spent $300M on Republican campaigns lost both politically and in the P&L on the same day.
Read at Financial Times ↗Southern Company (SO) reported a Q3 EPS beat and signalled its capital plan could approach $100B over 5 years as data-centre power demand targets 17% EPS growth. The stock rose more than 1% during Wall Street's sell-off — a signal that regulated utilities tied to the data-centre build-out may be more insulated than pure-play tech names even if AI-regulation risk materialises. Watch SO and NextEra as infrastructure proxies if the AI-regulation scare persists.
Read at Seeking Alpha ↗Friday's October nonfarm payrolls (8:30 a.m. ET, BLS) land the morning after the market's worst session in 18 months. CNBC Economy reports the consensus expects a print in the 150-180K range. A hot NFP (>200K) compounds the sell-off by pushing rate-cut expectations further out; a cool print gives bulls a rate-repricing floor. The read sets the tone for the November FOMC meeting and determines whether today's panic accelerates or stabilises.

Insider Form 4 activity today showed notable buys in ASPE and INTC — isolated, but INTC's leverage to any AI capex cycle makes the buy worth noting even in a disrupted environment. The $300M in Wall Street hedge-fund donations that backed Republican campaigns returned zero political ROI and cost them heavily in the P&L today. With the AI trade blown up, follow-on risk tomorrow is the NFP print: a hot number forces the market to hold elevated rate expectations INTO a sell-off, a toxic combo. Watch for gamma unwind at SPX 5300 and Nasdaq 100 19,000 strike clusters — options positioning at those levels could amplify Friday's move in either direction.
October NFP (8:30 ET)
First major data print post-midterm meltdown. Market needs a soft number (~150K) to stabilise; a hot print (>200K) could extend selling as it removes rate-cut optionality into year-end.
AI regulation clarity
New progressive officials (Raman LA, Mamdani NYC) have been vocal on data-centre moratoriums. Watch for any formal policy statements that quantify the regulatory risk — or walk it back.
Retail capitulation signal
CNBC reported retail sold the most in a single day since Covid. Retail exhaustion has historically preceded short-term technical bounces — watch for reversal signals in SMH ETF and QQQ flows at Friday open.
