## Key points

- A 7% decline would trigger the first market-wide trading halt.
- Tech shares and bitcoin fell as investors weighed election and rate concerns.

## Summary

The S&P 500 fell as much as 3.8% on Thursday, less than a day after Donald Trump celebrated record highs and rising retirement accounts. The sharp reversal erased the previous day’s rally and brought emergency market-wide trading halts into focus, though the first threshold had not been reached at the time of the report.

A 7% drop from the previous close would trigger a 15-minute halt before 3:25 p.m. ET; declines of 13% and 20% would bring further suspensions, with the final threshold stopping trading for the rest of the day. Technology shares led losses: the Nasdaq fell nearly 5% around 11 a.m. ET, Nvidia lost more than 6%, and the semiconductor index dropped nearly 11%. Bitcoin also fell below $76,000, while investors weighed election-related concerns about AI infrastructure oversight, inflation and the Federal Reserve’s next rate decision.
