W.040Four Taiwan server makers sold 99% more in October than a year before. Wistron alone sold NT$403B, about $12.5B
Wistron, Wiwynn, Gigabyte and Inventec reported combined October revenue of NT$715B in monthly filings on November 4–6, +99% on October 2025. Wistron’s sales rose +118% to NT$403B, about $12.5B, and Gigabyte’s +137%; Wiwynn’s rose +81% but fell 4% from September. Wiwynn’s shares fell 14.4% in a week when Taiwan’s market lost 12%.
The filings
October revenue for the four nearly doubled. Taiwan’s listed companies report revenue every month, by the 10th. Inventec filed on November 4, Gigabyte on November 5, and Wiwynn and Wistron on November 6. Together they reported NT$715B, against NT$359B in October 2025, a rise of 98.9%, and −0.1% from September. At October’s average exchange rate of NT$32.27 to the dollar, that is about $22.1B. Wistron alone was 56% of it. Hon Hai, the largest of Taiwan’s server makers, reported NT$1.31T, up 46%, which W.022 covered; Quanta had not filed by Saturday.
Wistron said the growth came from AI server shipments, and that it expects November and December to beat October, according to the Central News Agency. Its October was the second-highest month on record, 12% below August’s NT$460B. Gigabyte’s filing gave strong AI orders as the reason for its +137% rise. Wiwynn cited strong customer demand; with its third-quarter results it said, as reported by the Liberty Times, that tight supply of materials may make monthly revenue swing in the short term.
Every one of them grew by at least 46% on a year
October 2026 revenue against October 2025, %, from the companies’ monthly filings as relayed by MoneyDJ, cnyes and CNA. “The four combined” is the sum of their revenue in each month (our arithmetic). Accton, which makes network switches rather than servers, is shown in grey for comparison, at its reported growth rate.

Month to month
The step up came in August. Wistron’s revenue jumped to NT$460B in August from NT$308B in July, and has stayed above NT$380B since. Summed by month, its third quarter came to NT$1.15T, +28% on the second. Wiwynn’s third quarter was NT$435B, +56% on the second; it reported net income of NT$23.4B for the quarter on November 6. Its October was its second-highest month, below September.
Two of the four fell from September. Inventec’s October revenue was 19% below September’s; the reports reviewed for this post give no reason. Wiwynn’s was 4% lower. Monthly revenue at these companies moves with the timing of rack shipments, so a single month is a weak signal; on a year, all four grew.

The shares
The filings landed in a week when the stocks fell. The TAIEX closed at 39,701.64 on Friday, November 6, down 4.51% on the day and 12.19% on the week, in a selloff in AI chip shares that institutional investors quoted by CNA partly tied to the US midterm results, and that W.038 measured. Wiwynn fell 14.4% on the week and touched NT$1,555 on Friday, its lowest since its stock split; Hon Hai fell 8.6% and Quanta 8.2%, according to the United Daily News, which put the week’s loss of market value at six server makers at NT$672.2B. Wiwynn’s figures came out at about 1:54pm and Wistron’s in the evening, both after Taiwan’s market closed at 1:30pm on Friday, so Monday is the first session in which investors can trade on them.
Over ten months the growth is smaller but still large. From January to October, Wistron’s revenue was NT$3.29T, +100% on the same months of 2025; the four together reported NT$5.74T, +77%. Quanta said in August it expects its AI server revenue to double this year; its October figure is due by November 10.

What this changes on 06.ai
- Unit growth pack: the server makers’ monthly filings are the earliest hard data on AI rack shipments each month. A tracker of Wistron, Wiwynn, Quanta, Gigabyte, Inventec and Hon Hai monthly revenue would show the build-out a quarter before the hyperscalers report it.
- Watch Quanta’s and ASUS’s October filings, due by November 10, and Wistron’s guidance that November and December will beat October.

MOPS, the exchange’s filing system, could not be reached from where this was written; figures come from news services that republish the filings, and agree across at least two of them. 億 is NT$100M. Combined: October 402.6 + 165.1 + 80.0 + 67.0 = 714.7; October 2025 185.1 + 91.3 + 54.8 + 28.3 = 359.4 (sums of unrounded figures, here and below); 714.7 ÷ 359.4 − 1 = 98.9%; September 715.2, so −0.1%; January–October 5741.1 ÷ 3250.7 − 1 = 76.6%. Per company: Wistron 402.615 ÷ 185.062 − 1 = 117.56% (filed 117.56%); Wiwynn 165.132 ÷ 91.264 − 1 = 80.94% (filed 80.94%); Inventec 79.966 ÷ 54.766 − 1 = 46.01% (filed 46.02%); Gigabyte 67.036 ÷ 28.318 − 1 = 136.72% (filed 136.72%). Dollars: NT$ ÷ 32.2695; Wistron 402.6 ÷ 32.2695 = 12.48. Wistron against August: 402.6 ÷ 460.07 − 1 = -12.5%; share of the four 402.6 ÷ 714.7 = 56.3%. Quarters are sums of months: Wistron Q3 308.22 + 460.07 + 380.81 = 1149.10, Q2 283.44 + 290.18 + 321.82 = 895.44; Wiwynn Q3 434.62, Q2 278.15. Wiwynn’s Q3 sum matches its reported NT$434.618B. The exchange rate is the Federal Reserve’s New York average for October, not a Taipei rate. Share moves are as udn and Taiwan News reported them.
