Semiconductor selloff drags Bitcoin below $63,000 as equity futures sink

US equity futures declined sharply on July 17. A selloff in semiconductor stocks, triggered by disappointing earnings from Samsung Electronics and SK Hynix, spread to crypto markets. Nasdaq-100 futures dropped as much as 1.91% in premarket trading, erasing more than $2 trillion in semiconductor market value from late June peaks.

Bitcoin fell 1.2% to below $63,000. Ether dropped 1.74%. Hyperliquid's HYPE token shed more than 10% over the same session.

The Philadelphia Semiconductor Index had surged 88% in Q2 2026 on enthusiasm around AI infrastructure spending. When Samsung and SK Hynix delivered projections that fell short of investor expectations, the index began unwinding. It fell 7.9% on June 23 alone. Micron shares lost 13% in recent sessions. Intel dropped 21% over a single week in early July. Sandisk and AMD also took meaningful hits.

AMD, which lost 12% over the past week, carries an Alpha Score of 51 out of 100, indicating mixed sentiment. The stock page is here.

Crypto has increasingly traded as a high-beta extension of the tech sector over the past two years. When Nasdaq futures drop nearly 2%, Bitcoin tends to follow. This selloff is not an idiosyncratic crypto event such as an exchange hack or regulatory crackdown. It is a broad risk-off move driven by macro sentiment around technology spending.

Ether's decline is tied to the AI narrative. Much of the bullish case for Ethereum in 2026 has centered on its role in decentralized AI compute networks. When investors question whether AI infrastructure spending will meet expectations, that thesis takes a hit. HYPE's 10%-plus decline follows a similar pattern at the more speculative end of the spectrum.

The speed of the decline is notable. A 7.9% single-day drop in the Philadelphia Semiconductor Index is sharp, particularly for portfolios that used leverage to ride the Q2 rally. The correlation between semiconductor performance and crypto valuations means that chip earnings reports are now crypto events. Traders who ignore Samsung's guidance or Micron's revenue outlook are flying blind in a market where those data points increasingly dictate digital asset direction.

Intel losing a fifth of its value in a week and Micron dropping 13% go beyond semiconductor stories. They are repricing events for every asset class that benefited from the AI enthusiasm trade. Crypto sits squarely in that category. The Philadelphia Semiconductor Index closed at 4,882 on July 16, down 7.9% from its June 23 close.
