Google Slashes 2026 TPU Target 25% Due to Taiwan Semiconductor CoWoS Bottleneck

TSMTSM

Google cut its 2026 TPU output target from 4 million to 3 million units due to constrained access to Taiwan Semiconductor’s CoWoS advanced packaging slots, where Nvidia holds over 50% of capacity through 2027. Taiwan Semiconductor will double capacity by retrofitting fabs by 2028 to double revenue and cement AI hardware leadership.

1. Advanced Packaging Bottleneck Restricts AI Hardware Supply

Taiwan Semiconductor Manufacturing’s CoWoS advanced packaging capacity has become a critical constraint in the AI hardware supply chain. Industry reports indicate that leading cloud providers have had to revise down their 2026 accelerator carton targets by as much as 25% due to limited access to CoWoS slots. Nvidia has secured over half of available CoWoS capacity through 2027, leaving competitors battling for the remaining allocations. As CoWoS integrates logic dies with high-bandwidth memory on a silicon interposer, any shortfall directly translates into fewer deployable AI accelerators and delayed data-center expansions. This capacity squeeze underscores Taiwan Semiconductor’s outsized influence on AI market scaling—and highlights the strategic importance for hyperscalers to secure long-term packaging commitments.

2. Capacity Expansion Plan Poised to Double Advanced Nodes by 2028

To alleviate supply tightness, Taiwan Semiconductor is accelerating capital expenditures across its most advanced fabs. The company has committed to doubling its leading-edge wafer output by the end of 2028, including a significant ramp of 3-nanometer and 2-nanometer production. Additionally, management is repurposing selected 200-millimeter facilities to support advanced packaging processes, projected to increase CoWoS throughput by 40%. Analysts forecast that if these expansions execute on schedule, annual revenue could grow by more than 100% over the next three years. This aggressive capacity buildout aims to narrow the gap between demand surges driven by AI training and inference workloads, potentially easing supply allocation conflicts among major customers.

3. Institutional Stake Adjustments Highlight Confidence and Caution

In the third quarter, Dupont Capital Management trimmed its Taiwan Semiconductor position by 6.7%, reducing holdings to roughly 83,000 shares—now representing 2.4% of its total portfolio. Conversely, several new entrants established stakes during the same period, including 1248 Management and Heartwood Wealth Advisors. Overall institutional ownership remains robust, with hedge funds and asset managers collectively holding over 80% of outstanding shares. This mixed repositioning suggests that while investors recognize Taiwan Semiconductor’s pivotal role in AI infrastructure, some are also taking profits after a 50% price rally in 2025. The recent dividend increase to an annualized payout of $3.87 per ADR and a payout ratio near 26% further underscores management’s commitment to returning cash amid rapid cap-ex deployment.

4. Bullish Order-Flow Signal Signals Short-Term Trader Interest

On January 2, Taiwan Semiconductor triggered a proprietary Power Inflow alert, indicating a significant shift toward buying activity among both retail and institutional participants within the first two trading hours. Following this signal, trading volumes rose by 15% relative to the prior week’s average, and the stock outperformed peers during intraday sessions. Order-flow analytics providers note that such alerts have historically coincided with intraday gains averaging 2%. While not a long-term valuation metric, the Power Inflow signal reflects renewed trader conviction and may attract momentum‐driven flows in the near term.
