Taiwan Semiconductor Manufacturing Company, the world's largest contract chipmaker, is closing in on a $2 trillion market value as semiconductor stocks bounce back, according to a report published by MSN.

The rebound was broad. MSN reports that major chip stocks advanced sharply in Wednesday's premarket session, with Intel gaining 4% and the iShares Semiconductor ETF (SOXX) — a fund that tracks a basket of chip companies — climbing 2.6%. That kind of synchronized move suggests investors were buying back into the sector as a whole, not just one name.

According to MSN, the renewed optimism around TSMC was accompanied by a notable insider signal: a top executive bought the company's stock. When senior leaders put their own money into shares, investors often read it as a vote of confidence in the company's near-term prospects, though MSN does not detail the size or timing of the purchase.

A few words on the players. TSMC manufactures the advanced chips that power smartphones, data centers and the artificial-intelligence boom, making it a bellwether for the entire industry. SOXX is widely watched as a gauge of how the chip sector is trading overall.

Why it matters: crossing $2 trillion would put TSMC in the rarefied company of the world's most valuable corporations, and a sector-wide rebound — combined with an executive buying in — signals that investor appetite for the chips underpinning the AI era may be strengthening again.
