TSMC (2330) reported June 2026 revenue of NT$442.7 billion, up 6.16% from May and up 67.9% from June 2025, according to its monthly filing with the Taiwan Stock Exchange. Cumulative revenue for the first six months of 2026 is running 35.6% ahead of the same period last year. In a market where investor sentiment on artificial intelligence swings on rumor and survey data, this is the closest thing the world gets to an official monthly revenue reading on real semiconductor demand — and it points firmly upward.
TSMC: The Cleanest Read on AI Demand
The most striking feature of TSMC’s June print is not the headline growth rate but the gap between it and the year-to-date figure. Full-year-to-date revenue is up 35.6%, yet June alone grew 67.9% year-over-year — nearly double the cumulative pace. That spread strongly suggests growth accelerated versus the earlier first-half run rate. The earlier months of 2026 were growing well below the June rate, and the trajectory has steepened into mid-year.
The 6.16% sequential gain matters too. June is the final month of the second quarter, and a rising exit rate into the quarter close suggests demand was still building rather than plateauing when the books were ruled off. As a key manufacturer of leading-edge AI silicon, TSMC’s revenue serves as a broad, volume-weighted proxy for how much advanced silicon the industry is actually buying — not ordering, not forecasting, but paying for. On that measure, the AI build-out was still gathering pace in June.
The Rest of the Supply Chain: Strong, but Not Uniform
The other bellwethers that reported alongside TSMC tell a story of broad strength with distinctly uneven texture.
| Company (Ticker) | June 2026 Revenue (NT$B) | MoM | YoY | YTD Cumulative YoY |
|---|---|---|---|---|
| TSMC (2330) | 442.7 | +6.16% | +67.90% | +35.60% |
| Hon Hai / Foxconn (2317) | 821.8 | −4.38% | +52.11% | +34.99% |
| Delta Electronics (2308) | 65.6 | +11.26% | +55.43% | +41.02% |
| MediaTek (2454) | 58.0 | +22.30% | +2.80% | −0.77% |
| UMC (2303) | 23.1 | +0.79% | +22.85% | +11.28% |
Hon Hai (Foxconn), the largest company in the table by absolute revenue at NT$821.8 billion, grew 52.11% year-over-year even as revenue slipped 4.38% from May. The annual comparison is what counts here: as the dominant assembler of AI servers, Hon Hai’s growth rate corroborates the demand signal coming out of TSMC’s fabs one step downstream.
Delta Electronics posted the fastest cumulative growth of the group, with first-half revenue up 41.02% and June up 55.43% year-over-year alongside an 11.26% sequential gain. Delta’s power components and thermal solutions sit squarely in the data-center build-out, and its numbers move in visible sympathy with the AI names above it.
UMC offers the contrast. The mature-node foundry grew a respectable 22.85% year-over-year, but its near-flat month (+0.79%) and 11.28% year-to-date pace — roughly a third of TSMC’s — underline that this cycle is being driven by leading-edge capacity, not the broader chip market.
MediaTek is the outlier. A 22.30% jump from May looks impressive in isolation, but June revenue was up just 2.80% from a year earlier, and cumulative first-half revenue is actually down 0.77%. The divergence between MediaTek and TSMC could hardly be starker: demand for smartphone- and consumer-centric silicon is flat while AI infrastructure spending surges. The strong May-to-June move is worth noting, but one month does not yet reverse a negative half.
Why Taiwan’s Monthly Numbers Matter
Taiwan-listed companies are required to file monthly revenue with the exchange by the 10th of the following month — a disclosure cadence almost no other major market imposes. Where investors elsewhere wait a full quarter for hard numbers, Taiwan delivers an official demand reading every thirty days. That is why TSMC’s monthly release has become a global macro event in its own right: it is the earliest verified data point on the health of the AI trade, published on a fixed schedule, straight from the company’s own filing.
What to Watch
1. Whether TSMC’s acceleration holds in July. The gap between June’s 67.9% year-over-year growth and the 35.6% year-to-date pace is the defining feature of this report. If July’s filing, due by August 10, shows a monthly growth rate that again far exceeds the cumulative figure, the acceleration story is intact; convergence would suggest the steepest part of the ramp is behind us.
2. MediaTek’s cumulative line. First-half revenue sits at −0.77% year-over-year. Whether the strong sequential June (+22.30%) marks the start of a consumer-silicon recovery or a one-month blip will show up quickly in whether that cumulative figure turns positive over the coming filings.
3. Hon Hai’s sequential trend. June’s 4.38% month-over-month decline sits against 52.11% annual growth. The July number will indicate whether the dip was a pause in an otherwise steep ramp or the beginning of a flatter stretch for AI server assembly.
The next round of monthly filings is due by August 10.
