Massive AI Semiconductor Investment Underscores Crypto’s Shrinking Capital Share

Samsung Electronics and SK Hynix are accelerating semiconductor expansion plans by roughly a decade to meet surging demand for AI memory chips, highlighting the scale of the artificial intelligence investment cycle that has drawn capital away from crypto throughout the year.

The two South Korean chipmakers plan to invest about 800 trillion won ($518 billion) to build four new fabrication plants in the country’s southwest, according to a Monday announcement. The initiative is part of a broader national strategy to double DRAM output—key memory used in smartphones and computers—over the next five years.

A South Korean presidential adviser said AI-driven demand could bring completion timelines forward to 2034 or 2035, more than a decade ahead of the original 2044 target. SK Hynix has also announced plans for a roughly $29 billion U.S. listing to support further expansion.

The investment surge is centered on high-bandwidth memory (HBM), a critical component used in training AI systems and large language models such as ChatGPT and Claude.

SK Hynix has emerged as the dominant HBM supplier, briefly overtaking Samsung as South Korea’s most valuable listed company for the first time in 25 years. Together, the two firms dominate global HBM supply and have secured major contracts with Nvidia and OpenAI.

The scale of AI infrastructure spending underscores a broader capital rotation that has weighed on crypto markets. Digital assets have lagged for much of the year, even during AI-driven equity rebounds, reflecting shifting investor priorities.

According to Gabe Selby of CF Benchmarks, a growing share of risk capital has flowed into AI-related trades, compressing crypto’s share of overall market attention.

The shift is also visible across traditional hedge assets. Recent declines in gold, silver, and bitcoin during an unwind of defensive positioning saw capital rotate into AI equities rather than return to crypto.

Within the crypto industry, the trend is also evident, with some bitcoin miners reallocating computing capacity toward AI hosting services that offer more stable, contract-based revenues than mining.

South Korea’s $518 billion buildout reflects a long-term bet that AI infrastructure demand is structural rather than cyclical. Crypto, meanwhile, remains on the other side of that capital flow, raising questions about whether sidelined liquidity will eventually rotate back.

Bitcoin is on track to close the first half of 2026 below $60,000 and is trading near its 200-week moving average, a long-term technical level that has historically marked extended periods of weakness, with few near-term catalysts as capital continues to favor AI and semiconductor investments.
