US stock market wipeout today: claim unverified based on available data

A viral claim that over $700 billion was wiped from the US stock market today is unverified based on the available evidence. No authoritative confirmation from primary market regulators or major institutions has been identified for a single-session loss of that magnitude today.

Large one-day drawdowns of a similar scale have occurred recently, which may explain the claim’s prominence. As reported by The Economic Times, a January 2026 selloff saw the S&P 500 fall about 1.2%, translating into roughly $750 billion in investor wealth erased (https://m.economictimes.com/news/international/us/sp-500-drops-1-2-750-billion-wiped-out-as-big-tech-stocks-slide-and-greenland-comparison-stuns-markets/amp_articleshow/126833861.cms).

These precedents show the order of magnitude is plausible during concentrated selloffs in megacap technology. However, the specific assertion of a $700 billion US stock market wipeout today remains uncorroborated.

Immediate context: Magnificent Seven selloff, AMZN, Bitcoin ETF outflows

Recent market stress has been amplified by the Magnificent Seven selloff and broader AI-linked weakness. The Guardian documented that nine high-valuation, AI-related leaders collectively shed over $750 billion in market capitalization across several sessions in November 2025, underscoring concentration risk (https://www.theguardian.com/business/live/2025/nov/07/itv-talks-sell-broadcasting-arm-sky-shares-bank-of-england-stock-markets-business-live).

Amazon.com, Inc. (AMZN) has also been a focal point. As reported by AOL, AMZN endured its worst losing streak in two decades, a dynamic that can disproportionately weigh on capitalization-weighted indices given the company’s size (https://www.aol.com/articles/amazons-9-day-losing-streak-003031600.html).

Digital-asset flows add another pressure point. According to MSN, Spot Bitcoin ETFs saw about an $8.5 billion exodus, signaling a cooling of institutional demand that previously supported prices (https://www.msn.com/en-us/money/markets/bitcoin-price-falls-below-65-000-42-5-key-reasons-behind-the-1-21-trillion-wipeout-in-139-days/ar-AA1WUv53).

Traders on the floor have characterized the mood shift in stark terms. “Fear is back,” said Peter Tuchman, NYSE floor trader, as reported by Stocktwits (https://stocktwits.com/news-articles/markets/equity/einstein-of-wall-street-nyse-floor-says-fear-is-back-after-sp500-wipeout/cZbFRHAR4nK).

At the time of this writing, Bitcoin (BTC) was around $64,576 with a bearish sentiment and very high volatility of 11.03%, based on the provided metrics. These conditions can tighten financial conditions at the margin and influence risk appetite.

What to watch next and how to verify

Methodology: calculate S&P 500 market-cap loss with timestamps

To verify a “US stock market wipeout today” claim, compute the S&P 500 market-cap loss using a transparent, timestamped approach. Compare total index-level market capitalization at the prior close and the current close, ensuring both reference the same official session end.

For additional rigor, aggregate constituent-level market-cap changes for the largest weights and reconcile that sum to the index-level change. Document the timestamps and inputs to produce an auditable trail for the stated loss figure.

Signals: Fed commentary, AMZN performance, Spot Bitcoin ETF flows

Monitor Federal Reserve commentary for shifts in the policy path that affect discount rates and risk premia, which can disproportionately impact megacap growth valuations. A more hawkish tone would typically pressure multiples.

Track AMZN’s price action and liquidity, as extended drawdowns in such a heavyweight can drive headline S&P 500 market cap loss. Recent weakness has coincided with broader megacap underperformance.

Watch Spot Bitcoin ETF net flows, as prior reports highlighted a material outflow wave. Sustained outflows can dampen crypto-linked risk sentiment that often coheres with broader equity risk-taking.
