Taiwan Semiconductor Gains 2% to Record as Musk Confirms Early Terafab Talks; Broadcom Rises 2%, Qualcomm Pulls Back

Early-stage, unconfirmed talks with Terafab, a chip-manufacturing venture planned for Texas, have sent Taiwan Semiconductor Manufacturing (NYSE:TSM | TSM Price Prediction) stock to a record. Taiwan Semiconductor stock is up 2% to $484.19 in midday trading, after touching an intraday record high during the session. No agreement has been announced, so the rally rests on what Taiwan Semiconductor might gain from a role in the venture’s Texas factories.

Sector funds tell a different story than the record in Taiwan Semiconductor stock, and they show how narrow the move is. Meanwhile, the iShares Semiconductor ETF (NASDAQ:SOXX) is down 0.3%, leaving the broader chip group slightly lower. The Invesco QQQ Trust (NASDAQ:QQQ) is up 0.6%, a modest lift for large-cap tech.

Also, Broadcom (NASDAQ:AVGO) stock is up 2%, keeping pace with Taiwan Semiconductor shares. Qualcomm (NASDAQ:QCOM) stock is down 2%, breaking from both names as the chip group splits. That split, paired with a slipping semiconductor fund, points to a catalyst specific to Taiwan Semiconductor.

Early Terafab Talks Lift Taiwan Semiconductor

Technology journalist Tim Culpan reported in his newsletter that Taiwan Semiconductor is exploring ways to work with Terafab to help run new chip factories in Texas. Tesla (NASDAQ:TSLA) CEO Elon Musk responded on X over the weekend, describing the early-stage talks as “just discussions” while writing that something may come of it. Musk’s plan calls for a large chip factory supplying his car, rocket and artificial intelligence (AI) companies, giving the venture a built-in customer base.

Intel (NASDAQ:INTC) joined Terafab in April and remains a named partner in the venture. That standing gives the report extra weight, since any role for Taiwan Semiconductor would change the structure of a partnership Intel already holds, as adding the world’s largest foundry could give Terafab a deeper bench of manufacturing expertise for its planned Texas factories.

Taiwan Semiconductor Leads While Qualcomm Lags

Taiwan Semiconductor stock is up 61% year to date (YTD), so the Terafab headline lands on shares that had already run hard. The company has ridden demand tied to the AI buildout all year, and a new American fab project could add to a business already running hot. AI-driven orders for leading-edge chips have powered Taiwan Semiconductor’s growth, and the Terafab report adds a fresh U.S. angle to that story.

A role in a high-profile Texas project would also expand Taiwan Semiconductor’s U.S. manufacturing footprint, which already includes fabs in Arizona, yet Musk described the early-stage talks as discussions and nothing more, so Taiwan Semiconductor stock is pricing in the possibility of an arrangement.

Broadcom sells custom accelerators and networking chips into the same AI expansion, supplying some of the largest data-center operators. That exposure fits Broadcom stock tracking Taiwan Semiconductor shares higher. AI infrastructure demand continues to support both companies (we covered seven of these non-chipmaker AI suppliers, from power to cooling, in a free report you can grab here).

Qualcomm stock is sliding even as two of the largest chip names rise. Handsets, automotive chips and connected devices drive much of Qualcomm’s business, leaving the company without a direct link to the early-stage Terafab discussions.

What to Watch Next

Early-stage discussions that Terafab’s founder won’t call a deal can fall apart quickly if nothing follows, and that’s a central risk for Taiwan Semiconductor stock at a record. Investors should look for any sign the unconfirmed talks produce terms, such as a defined role for Taiwan Semiconductor in the Texas factories. A formal announcement from either side could give Taiwan Semiconductor stock steadier foundation than a social media post.
