Bitcoin declined to ten-day lows below $63,000 at the open of United States trading on Tuesday as losses in Asian semiconductor shares spread to Wall Street. The move reflected broader pressure on technology stocks tied to artificial intelligence infrastructure spending.

South Korea’s KOSPI index closed down 10.8 percent, driven by a 14.8 percent drop in chipmaker SK Hynix. Japan’s Kioxia Holdings fell 18.3 percent. In the United States the Nasdaq Composite Index declined just over 1 percent. Semiconductor producer Micron Technology dropped more than 10 percent at the open and reached its lowest level since late May.

Investors have intensified scrutiny of capital expenditure plans by major technology groups. Combined 2026 guidance from Alphabet, Microsoft, Amazon and Meta is tracking toward $725 billion to $730 billion and could approach $900 billion in 2027. Alphabet recorded its first quarterly cash burn of $5.9 billion in the second quarter even as its cloud division grew 82 percent. Competitive pressure from Chinese artificial intelligence developers has added to concerns that Western hyperscaler spending may face lower returns if comparable capabilities emerge at lower cost.

Bitcoin traded below $63,000 for the first time since July 17. Cryptocurrency markets recorded more than $510 million in long liquidations over 24 hours. Large accumulations of leveraged long positions below $64,700 have raised the possibility of further forced selling, while the zone between $65,800 and $66,200 remains a concentration of short positions.
