The cooperation scenarios discussed include SK Hynix possibly leasing part of an Intel facility or forming a joint venture with Intel and large cloud players to build new memory capacity in the U.S., according to Note on September 18, 2026.

Sector context and valuation signal

The move came against a broader semiconductor upswing. As TechFlowPost reports on September 18, 2026, Intel gained 7.7 percent in the latest session while peers such as Arm Holdings, Advanced Micro Devices and Micron Technology also posted rises between roughly 5.5 and 8.6 percent.

This sector-wide strength reflects strong demand for AI infrastructure and server components, a theme highlighted by Traders Union, which notes that as of September 18, 2026, Intel stands out within the broader technology upswing and is currently trading above USD 106.50 while chart watchers eye resistance near USD 114.

The rally has also raised questions about valuation. On September 17, 2026, GuruFocus calculated Intel’s GF Value metric at USD 32.05 per share, compared with the USD 108.80 close that day, implying the stock is about 239.5 percent above this intrinsic-value estimate as investors increasingly price in future growth.

In addition, commentary from Sina Finance notes that Intel shares briefly spiked more than 10 percent intraday on September 17, 2026 before closing with the 7.67 percent gain, and that the company’s market capitalization increased by roughly USD 407 billion in local-currency terms during the session.

Risk factors: cooperation uncertainty and valuation

While investors welcomed the prospect of a U.S. memory-manufacturing partnership, some uncertainty remains around the SK Hynix talks. As Sina Finance reports on September 18, 2026, SK Hynix has stated that it is studying various options to strengthen global competitiveness but has not yet made any concrete decisions on cooperating with specific companies or on producing memory chips in the United States.

This caveat underscores that part of Intel’s recent share-price strength is driven by expectations rather than signed contracts, which could introduce volatility if negotiations do not result in a formal agreement or if project economics change.

Combined with GuruFocus’ view that the stock now trades materially above its GF Value estimate,GuruFocus the current level implies that the market is pricing in robust growth in Intel’s foundry and AI businesses over the coming years, increasing sensitivity to execution risks.
