A Sharp Slide for the Chipmaker

The 29% drop represents a dramatic loss in market value for Intel, whose stock had already been under pressure amid intensifying competition in the semiconductor industry. The decline was documented in a Newsis photo file dated September 18, 2025, sourced from AP and the Newsis archive.

Context and Uncertainty

The available source material confirms the magnitude of the fall but does not detail the specific cause of the sell-off, the exact trading session in which it occurred, or the closing share price. Investors and industry watchers in Korea and abroad have been closely tracking Intel's position in the CPU and foundry markets, where the company faces competition from rivals including Samsung, TSMC, and SK hynix's strength in the HBM segment. However, no direct link between those competitive dynamics and this particular decline is established in the reviewed material.

Readers should note that the underlying research does not specify whether the fall was tied to earnings guidance, restructuring news, or broader market movements, and no company statement is included in the source set.

Conclusion

The reported 29% collapse in Intel's share price is consistent with the source material on record. The claim that Intel's stock plunged 29% is True.
