Intel shares climbed more than 40% during September 2026, extending a year-to-date gain of more than 200% and raising questions about whether the chipmaker's valuation has outrun its fundamentals. For a company whose processors anchor a large share of the world's PCs and servers, a monthly move of that size underscores how quickly sentiment around AI-exposed chip stocks can shift.

The stock peaked above $127 intraday before settling around $123 at the end of the month. A single session on September 21 delivered a 12.14% jump, among the strongest daily moves of the rally.

What Is Driving the Rally

Two forces converged to fuel the advance. The first was Meta Platforms' rollout of its Muse AI agent, which sharpened market expectations for data-center CPU demand. The second came from CEO Lip-Bu Tan, who told investors that Intel can currently meet only about 50% of existing CPU demand — a figure that, at Intel's scale, means growth is currently limited by production capacity rather than by customer demand.

The company reported Q2 2026 revenue of $16.1 billion, a 25% increase year over year. Progress on the foundry side added further momentum, including discussions with SK Hynix on potential memory-chip manufacturing partnerships. Foundry work — manufacturing chips designed by other companies — is the linchpin of that strategy, since success would let Intel capture manufacturing volume well beyond its own product line, and the SK Hynix talks, still at the discussion stage, stand as an early milestone to watch. Analyst upgrades followed, with Melius Research lifting its price target to $165.

The Valuation Problem

Intel now trades at more than 60 times forward earnings. Forward multiples are measured against projected rather than current profits, so a reading above 60 embeds expectations of sustained rapid growth and leaves little cushion for execution missteps. The stock had previously changed hands as high as $142 earlier in 2026 before pulling back. The $165 Melius target implies roughly 34% upside from September's close.

The Comeback in Context

Lip-Bu Tan took the helm with a mandate to make Intel's foundry strategy profitable, and the 25% revenue jump in Q2 indicated that demand for the company's products is genuinely accelerating.

The competitive backdrop remains demanding. Nvidia retains its dominance in AI training chips, while AMD has carved out meaningful share in data-center CPUs — a reminder that Intel is competing for growth in segments where rivals already hold strong positions.

Attention now turns to whether Intel can sustain revenue growth above 20% in the coming quarters, whether its foundry business can move from cash drain to cash generator, and whether the SK Hynix discussions advance into firm commitments. the first two, the stock at more than 60 times forward earnings amounts, in effect, to a leveraged bet on AI demand continuing to accelerate.
