Philadelphia chip index enters bear market; about $3.3 trillion in global chip value erased since June 22
The Philadelphia Semiconductor Index (SOX) fell as much as 5.7% on Friday, July 17, 2026, deepening its drop from a late-June record to more than 20% and pushing the gauge into bear-market territory. According to Bloomberg data, roughly $3.3 trillion in global chip-stock market value has been erased since June 22. Before this slide, the 30-stock benchmark had soared about 105% from its March low to last month's peak. Shares of Marvell, ARM and Intel have each fallen more than 30% over that span. Friday's decline followed worries that the heavy spending on artificial intelligence is becoming harder to justify, compounded by the unveiling of the "Kimi K3" model by Chinese startup Moonshot. By Friday midday US Eastern time, Wall Street's main indexes were also trading lower, and Netflix shares dropped about 11% after a weak sales outlook. The selloff has no direct bearing on Iran's markets, but it reinforces a broad risk-off mood that feeds through to oil, gold and crypto prices.

China's Moonshot unveils Kimi K3 AI model as chip stocks tumble worldwide
Chinese startup Moonshot AI on Friday, July 17, 2026, unveiled its new AI model, Kimi K3. The company says the model, with 2.8 trillion parameters, is the world's largest open-weight model and trails only the most advanced US models on benchmark tests. The full model weights are due for public release on July 27. The launch triggered a wave of selling in semiconductor and AI stocks, with investors comparing it to the 2025 DeepSeek moment, when a Chinese lab released a model on par with US rivals at a fraction of the cost. The Philadelphia Semiconductor Index (SOX) fell about 24% from its late-June record on Friday, formally entering a bear market and heading for its worst week since spring 2025. Moonshot, backed by Alibaba, has been valued at around $31.5 billion in an ongoing funding round.
