Bitcoin slid below 76,000 dollars on November 5, 2026, touching its lowest level since September 16, as a broader selloff in technology stocks spread to other high-risk assets. The iShares Semiconductor ETF plunged 12.15% in the same session, its worst trading day since the COVID-19 pandemic crash.

Why it matters

The decline erased Bitcoin's post-midterm-election gains, which had lifted the cryptocurrency from 77,000 dollars to just above 81,000 dollars, and signals that the AI-sector selloff is reaching beyond equities. Investors are reassessing risk across technology and digital assets at the same time.

The iShares Semiconductor ETF recorded a 12.15% single-session decline, its steepest since the COVID-19 crash, while Bitcoin fell from roughly 81,000 dollars to below 76,000 dollars. The stub does not specify the underlying chip-sector triggers behind the drop.

The details

The Bitcoin decline extended a broader selloff across technology stocks to other high-risk investment assets. Post-midterm-election gains that had carried Bitcoin from 77,000 dollars to above 81,000 dollars evaporated on Thursday as AI-sector shares fell sharply.

September 16, 2026: Bitcoin previously reached its lowest level before the November decline.
November 3, 2026: US midterm elections were held, with Democrats gaining control of both chambers of Congress.
November 5, 2026: The semiconductor ETF plunged 12.15% and Bitcoin fell below 76,000 dollars.

Market Dynamics

The semiconductor ETF's 12.15% single-session decline is its worst since the COVID-19 pandemic crash, placing this selloff among the most severe chip-sector drops in recent years. The move shows how sharply AI-linked equities can reprice when risk appetite shifts across technology and digital assets.

Investors holding semiconductor funds or Bitcoin have seen sharp near-term losses after the November 5 selloff. Those with retirement or brokerage exposure to technology stocks may want to review their allocations as volatility persists.

The takeaway

Sharp single-day moves in semiconductor and crypto assets often signal broader risk repricing rather than isolated events. Reviewing portfolio concentration in AI-linked holdings can help limit exposure to similar drawdowns.
