What's happening
A Forbes analysis dated June 27, 2026 assesses whether Intel's 18A process node and associated manufacturing innovations represent a credible challenge to TSMC's leadership in advanced semiconductor foundry services. Central to Intel's technical differentiation is PowerVia, its backside power delivery architecture. As described in Intel's own newsroom materials and highlighted in papers presented at the 2023 VLSI Symposium, PowerVia involves building transistors and interconnect layers in the conventional sequence, then flipping the wafer and polishing it to expose the bottom layer, to which power delivery wires are then connected — effectively enabling two-sided chipmaking for the first time. Intel reported positive performance results from manufacturing and testing of this process.
In terms of production scale, Intel manufactured an estimated 3–5 million chips over the past year, a figure that contrasts sharply with TSMC's approximately 17 million chips over the same period. Projections for Intel's output in 2027 stand at roughly 4–6 million chips. A significant commercial catalyst has emerged in the form of Apple's decision to use Intel for chip manufacturing, a development that has been cited in connection with Intel's sharp stock appreciation. Intel's share price, which traded near $20 for an extended period before rising to approximately $50, subsequently spiked in March and has since climbed above $120 — a gain of roughly 500% over a compressed timeframe. Intel's current market capitalization stands at approximately $644.94 billion, with a 52-week range of $18.97 to $141.45.
Why it matters for markets
The foundry competition between Intel and TSMC carries direct valuation implications for both companies. TSMC currently commands a market capitalization of $2.24 trillion, a price-to-earnings ratio of 37.5, and annual revenue of $4.10 trillion, reflecting its entrenched position as the primary high-volume manufacturer for clients including Apple, Nvidia, and AMD. Any meaningful diversion of advanced-node orders — particularly from a customer of Apple's scale — toward Intel Foundry Services would represent a structural shift in the revenue base that underpins TSMC's premium valuation. The volume gap remains substantial: TSMC's approximately 17 million chips per year dwarfs Intel's current 3–5 million, and even Intel's projected 4–6 million chips in 2027 would leave a wide production differential.
For Intel, the financial trajectory has already shifted materially. The company's stock appreciation from approximately $20 to above $120 — roughly a 500% move — reflects the market's reassessment of Intel's foundry prospects following the Apple partnership announcement. Intel's annual revenue stands at $53.76 billion, and its expanded role in contract manufacturing via Intel Foundry Services represents a strategic pivot that could alter the company's revenue mix over time. The PowerVia backside power delivery technology, if adopted at scale, could serve as a process-node differentiator that attracts additional fabless clients currently reliant on TSMC.
The broader implication for the semiconductor foundry sector is a potential bifurcation of advanced manufacturing capacity between two credible suppliers at the leading edge, rather than the near-singular dominance TSMC has exercised. Whether Intel can close the volume gap and sustain yield performance at advanced nodes will be a key determinant of how foundry market share — and the valuations tied to it — evolve over the next several years.
Sectors and assets to watch
The two primary tickers directly implicated in this competitive dynamic are TSMC (TSM) and Intel (INTC). TSMC's position as the world's largest dedicated foundry, with 76,907 employees and process nodes ranging from 3nm to mature technologies, gives it structural advantages in yield maturity and customer diversification that Intel has not yet matched at scale. Intel, with 85,100 employees and an expanding Intel Foundry Services division, is the direct challenger, and its 18A node with PowerVia backside power delivery represents its most technically ambitious manufacturing offering to date.
Beyond these two primary subjects, the foundry competition has implications for fabless semiconductor companies that currently rely on TSMC for advanced-node production, as well as for the broader ecosystem of packaging, equipment, and materials suppliers that serve both manufacturers. Companies operating in advanced semiconductor equipment and those providing specialized packaging technologies are positioned at the intersection of both supply chains, making them sensitive to shifts in foundry capacity allocation and capital expenditure decisions by either TSMC or Intel.
What to watch next
Key developments to monitor include Intel's ability to scale 18A production volumes toward the projected 4–6 million chip range by 2027, and whether additional major fabless clients beyond Apple formally commit to Intel Foundry Services for advanced-node production. On the TSMC side, any commentary regarding customer concentration, pricing adjustments at leading-edge nodes, or capacity expansion plans in response to Intel's competitive positioning will be relevant to assessing how the foundry market share balance may shift. Technical disclosures from Intel regarding PowerVia yield rates and defect density at volume production — metrics that determine commercial viability — will also be closely watched by industry analysts tracking the competitive gap between the two manufacturers.
