The PHLX Semiconductor Index cratered nearly 20% this week, erasing roughly $1.5 trillion in market value. The selloff, which accelerated through Thursday and Friday, marks one of the steepest declines for the chip benchmark in recent memory. As semiconductor stocks get hammered, analysts are turning their attention to Bitcoin ETF inflows, looking for evidence that money is rotating out of chips and into crypto.
What hit the chip stocks
The index's slide began early in the week and deepened as earnings warnings from several major chipmakers hit the tape. By Friday's close, the PHLX Semiconductor Index had lost nearly a fifth of its value. The $1.5 trillion in erased market cap is a stark reminder of how much weight the sector carries in broader equity markets. No single catalyst was cited, but a combination of inventory gluts, softening demand, and geopolitical trade jitters weighed on sentiment.
Bitcoin ETF inflows under the microscope
With equities in turmoil, some market participants are betting that institutional capital could rotate into digital assets. Analysts are closely monitoring daily inflows into spot Bitcoin ETFs, which have seen sporadic bursts of buying during past equity selloffs. The question is whether this time is different. If ETF data shows a sustained uptick in inflows over the next few trading sessions, it could signal that investors are treating Bitcoin as a portfolio hedge or a tactical reallocation target.
What the data shows so far
Bitcoin ETF flows have been mixed this month. Early July saw modest net inflows, but the pace slowed as the semiconductor index started to wobble. The real test will come next week, when the full impact of the chip rout is priced in and traders decide where to park cash. A clear divergence — rising ETF inflows alongside falling chip stocks — would strengthen the rotation narrative. For now, it's a waiting game.
The coming days will show whether that rotation materializes. Monday's open will be the first real test, with ETF flow data due out Tuesday morning.
