Philadelphia Semiconductor Index Nears Record First‑Half Gain
The Philadelphia chip index advanced roughly 94% during the first half of 2026, marking its second‑strongest performance since the benchmark’s inception in 1994. Only the approximately 96% surge recorded during the 2000 dot‑com boom exceeds this gain.
Demand for data‑center chips, propelled by artificial‑intelligence applications, together with heightened capital‑expenditure programmes by hyperscale cloud providers, has underpinned the rally. Memory and data‑center suppliers such as Micron Technology and Qualcomm have issued robust forecasts, further reinforcing the upward trajectory.
The semiconductor rally has also contributed to record‑high levels across Wall Street’s primary equity indexes.
Within the sector, Micron Technology leads with a 300% year‑to‑date increase, followed by Intel Corp. with a 257% rise and Marvell Technologies with a 227% gain. In May, Micron’s market capitalisation briefly crossed the $1 trillion threshold, temporarily surpassing the valuations of Meta Platforms and Tesla.
Daily price movements noted in the report include Intel up 6.65%, Qualcomm down 1.18%, Marvell up 5.27% and Micron up 0.42%, while the broader SOX index was up 3.18%.
