AI boom strains TSMC capacity, creating semiconductor bottleneck

Broadcom warns supply chain 'choke' through 2026 as advanced node pricing climbs

Taiwan Semiconductor Manufacturing Company, the world's largest contract chipmaker, has reached production capacity limits as surging demand for artificial intelligence hardware creates a widening bottleneck across the semiconductor supply chain, according to warnings from Broadcom.

Natarajan Ramachandran, a director in Broadcom's Physical Layer Products division, described TSMC's capacity—which he previously would have characterized as "infinite"—as now constrained by unprecedented AI accelerator demand. The foundry giant raised prices for advanced node chips by 3-10% in January 2026, with sub-5nm processes including 2nm, 3nm, 4nm, and 5nm technologies seeing the steepest increases for AI-related applications.

The supply chain strain extends beyond silicon itself. Lead times for printed circuit boards have stretched from six weeks to six months, while laser components face similar constraints. Analysts project that meaningful capacity expansion won't materialize until 2027, leaving the industry navigating shortages through at least the end of this year.

Broadcom has secured supply commitments through 2028, positioning the company advantageously against competitors lacking similar leverage. The firm's shares rose 4.1% this week, reflecting investor confidence in its secured position. Analysts have responded by raising price targets to $480-$500, citing the company's ability to navigate supply constraints that threaten smaller players.

The consequences are rippling across industries. The intense demand from AI data centers is forcing a "strategic reallocation" of chip manufacturing capacity that could reduce automotive production by 600,000 vehicles in 2026, with AI infrastructure potentially consuming up to 70% of all memory chips. TSMC, trading at $338.45 with a market capitalization of $1.7 trillion, has an analyst consensus target of $430.65, suggesting room for further appreciation if capacity concerns ease.

For smaller semiconductor companies and original equipment manufacturers, the constraints present mounting pressure on margins and delivery timelines. With advanced node prices expected to continue rising through 2029, the economics of AI hardware are being fundamentally reshaped, favoring companies with the scale to secure long-term supply agreements.
