Top Market Signals

Samsung talks collapse, 18-day strike confirmed for 21 May

Samsung Electronics (005930 KS) labor negotiations broke down on 13 May, leaving eight days until a 41,000-strong, 18-day walkout begins at the world's largest memory chip operation; Shenzhen spot prices for DDR4 8Gb 3200 jumped 20% within hours.

Government-mediated talks under South Korea's National Labor Relations Commission ended without resolution after two days of marathon sessions. The gap was on bonus structure: the union wants the existing 50% cap on performance pay scrapped and 15% of operating profit allocated to bonuses. Samsung offered 10% of operating profit plus a one-time special compensation, which union representative Choi Seung-ho rejected as falling fundamentally short. The union said it will not return to talks before the 21 May start date.

Prime Minister Kim Min-seok responded by convening an emergency ministerial meeting, instructing officials to manage what his office called the potential gravity of the impact on the national economy. JPMorgan estimated that an 18-day stoppage would cost Samsung over KRW4tn (~US$2.8bn) in direct revenue, roughly 1% of the semiconductor division's annual sales. Seoul Economic Daily cited a Univ. of Seoul professor's projection of approximately KRW1tn (US$700m) per day in factory losses. The union's own estimate runs as high as KRW30tn (US$20.3bn) in total damages.

The market reaction was instant and on the price tape. According to China Flash Market (CFM), DDR4 8Gb 3200 spot in Shenzhen Huaqiangbei moved to US$18 over the week, up 20%, ending several weeks of declines. Server DDR5 was already climbing on its own AI-driven curve: 64GB RDIMM at US$1,350, +11% month on month, with 96GB also +10%. NAND wafer prices for 1Tb QLC, 1Tb TLC and 512Gb TLC all flipped from down to flat.

The Taiwan read-through goes to the two listed DRAM makers Samsung competes most directly against in DDR4 and niche DRAM. Nanya Technology (2408 TT) and Winbond (2344 TT) are now the marginal price-setters for any redirected orders, and industry contacts cited by Economic Daily expect the customer-psychology effect on inventory pulls to outweigh actual Samsung output losses. Korean media also reported that Apple and HP have called Samsung directly to assess strike risk and are signaling readiness to divert orders to CXMT in China and to TSMC adjacent foundries.

TSMC board commits another US$20bn to Arizona on top of US$31bn 2026 capex

Taiwan Semiconductor Manufacturing Company (2330 TT) directors approved a US$31.28bn 2026 capital budget on 12 May and a separate authorization to inject up to US$20bn into the TSMC Arizona subsidiary, the largest single capex action of the cycle and a clear signal that AI chip demand still exceeds capacity.

The Arizona ringfence is over and above the headline 2026 capex line. The capital budget itself covers advanced node, advanced packaging, mature and specialty capacity, plus new fab and facility construction. Local press reported P2 will start 3nm production in 2H27, P3 has topped out and is in equipment install, and P4 plus the first US advanced packaging fab will break ground mid-2026. That is four leading-edge logic shells and the firm's first overseas packaging plant, all live at the same time.

The board also approved a 1Q26 cash dividend of NT$7 per share, a record. Ex-dividend date is 16 September with payment on 8 October, releasing NT$181.5bn in cash. The National Development Fund, which holds 1.6537bn TSMC shares, takes home approximately NT$11.5bn from this payment alone.

The capex commitment lands on the same week as confirmation that supply chain partners are following TSMC into Arizona. Equipment maker Lam Research separately announced 1,000 Taiwan engineering hires for 2026, and Japanese photoresist supplier JSR formed a Taiwan joint venture with Wah Lee Industrial and LCY Chemical to build its first Taiwan plant in Yunlin County, scheduled to come online as early as 2028 and to co-develop advanced photoresists with TSMC. The picture is the same on both sides of the Pacific: capacity, materials, equipment and packaging are all expanding around the same gravity well.

Phison four-month profit already exceeds full-year 2025

Phison Electronics (8299 TT) self-reported April net income of NT$7.64bn, more than 61 times the year-prior month, with single-month EPS of NT$34.56. Against a NT$10 share par value, that is more than three times par earned in 30 days, and four-month cumulative EPS already exceeds NT$100. No Taiwan memory company has previously done this.

April standalone revenue hit NT$20.207bn, an all-time monthly high and up 236.63% year on year. Four-month cumulative revenue is NT$61.174bn, up 208.32% year on year. The April single-month year-on-year EPS comparison runs at +6,746%, off a tiny prior-year base, but the absolute pace is the story: the firm earned roughly half of its full 1Q26 profit in a single month.

The mechanism is two pressures hitting at once. NAND Flash demand has reset on AI inference deployment, with the read pattern shifting from training to large-scale inference where storage rather than HBM is the binding resource. Phison's 1Q26 gross margin reached 61.3% on this mix, and CEO Pan Jianchen has reframed the company as an "AI storage infrastructure and edge AI compute platform supplier." Phison has built inventory to NT$72.2bn, equal to roughly a quarter of run-rate revenue, and is raising more cash to extend that buffer.

The 4 May Blade flagged Phison's net income +1,230% YoY on NAND tightening; today's print is the same trajectory one rung steeper. The market has paid for the upgrade. Phison shares ran from NT$1,555 in late April to a NT$2,860 record before settling, a near-doubling in under three weeks, with R&D headcount of 3,500 in Taiwan and FY26 R&D spend now guided north of NT$20bn.

Cerebras prices IPO at US$185 after ARM and SoftBank tried to buy it first

Cerebras Systems is poised to price its US initial public offering at US$185 per share, the upper end of its expected range, raising approximately US$4.8bn at a fully-diluted valuation that places the AI accelerator maker among the most valuable post-IPO chip companies of the year; ARM Holdings and SoftBank made a separate approach to acquire the company outright weeks before the listing, and were rebuffed.

The pricing details were confirmed by Bloomberg-cited people familiar with the matter and disclosed alongside the company's filing. Cerebras designs wafer-scale processors that compete with NVIDIA and AMD in AI training and increasingly in inference, and counts OpenAI as a customer behind its newly announced GPT-5.3-Codex-Spark model run on Cerebras hardware. The IPO is a clean read on investor appetite for a non-GPU AI accelerator at scale.

The ARM and SoftBank approach is the more strategic data point. ARM is owned by SoftBank, and the two parties pursuing Cerebras together suggests a coordinated effort to bring wafer-scale accelerator IP under one umbrella before it is locked into the public-market hands. Cerebras choosing to list rather than sell at the offered price implies its board values independence at this point in the AI cycle, and frames the upcoming IPO as the public-market reference price for non-NVIDIA AI silicon.

The signal connects back to the same supply-shortage dynamic visible in HBM and CoWoS: customers are looking past general-purpose GPUs not because they doubt NVIDIA, but because they cannot get enough capacity through any single source. Cerebras pricing at the top of its range while AMD's Marvell stake and Anthropic's funding round are revealed in the same week tells the same story from three different angles.

Anthropic raising US$30bn at US$900bn, overtakes OpenAI in business adoption

Anthropic PBC is in early talks with investors to raise at least US$30bn in fresh financing at a valuation around US$900bn, and crossed OpenAI in B2B adoption for the first time per Ramp data showing 34.4% of surveyed companies paying for Anthropic services, a narrow but unprecedented lead over OpenAI.

The valuation, if achieved, would put Anthropic on a par with the largest pre-IPO technology private rounds ever priced, and at roughly the same scale as OpenAI's most recent secondary marks. The capital is being raised to fund model training, enterprise rollout, and the company's expanding cloud commitments, including the AWS Bedrock partnership announced this week to bring Anthropic frontier models directly to Amazon Bedrock customers.

The Ramp B2B data point matters because it is the first observed instance of OpenAI losing the corporate spend share war, even by a narrow margin. The trajectory is the question: Ramp's series shows Anthropic taking share month after month through the spring of 2026, while OpenAI plateaued. Sectoral data shows Anthropic is particularly strong in legal, with new connectors targeting that vertical, and is now courting small business owners directly. OpenAI counterpunched with the launch of an enterprise deployment unit and the Daybreak cybersecurity research initiative, which on benchmarks appears to overlap closely with Anthropic's own Glasswing security model.

The compute read-through is the obvious one. Both firms are buying more silicon than they can find. Microsoft has now spent over US$100bn on its OpenAI partnership to date, and the latest Microsoft revenue-share renegotiation caps Microsoft's claim on OpenAI revenue at US$38bn going forward. The two AI labs together represent the bulk of the demand pull on NVIDIA, AMD and the custom ASIC ecosystem; their funding cadence is the leading indicator for AI infrastructure spend.

JSR builds first Taiwan plant for advanced chip chemicals

JSR, the Japanese chemicals supplier that holds roughly a quarter of the global photoresist market, has formed a joint venture with Wah Lee Industrial and LCY Chemical to build its first photoresist plant in Taiwan, located in Yunlin County and coming online as early as 2028 to co-develop advanced photoresists with TSMC; this closes the gap that left JSR the last of Japan's three leading EUV-class resist suppliers without Taiwanese manufacturing.

EUV-grade resists are the light-sensitive chemicals that print circuit patterns onto silicon at 2nm and below. Each new process node requires a reformulation, and the highest-volume customers consume bespoke resists that must be qualified close to the fab to limit shelf life and contamination risk. Tokyo Ohka Kogyo and Shin-Etsu, the other two of the Japanese big three, already operate Taiwan capacity. JSR's arrival completes that picture.

JSR is also ramping the world's first production-scale facility for metal oxide resist in South Korea, a next-generation EUV chemistry the firm acquired through its US$514m Inpria purchase in 2021. Together with the new Taiwan plant, this represents a coordinated push to lock JSR's chemistry into the development pipelines of leading-edge fabs before Chinese competitors can close the gap.

The strategic context: JSR delisted in June 2024 after Japan Investment Corporation took it private at a JPY909bn (US$6.4bn) valuation, and the new owners have moved decisively to concentrate the company on semiconductor materials. Taiwan EUV resist supply was the missing piece. The same dynamic that drove TSMC supply chain partners to follow it into Arizona is now pulling Japanese materials makers into Yunlin. Read-through goes to Wah Lee Industrial as the local JV partner and to advanced packaging-adjacent materials names that may follow the same playbook.

MediaTek runs TSMC and Intel packaging in parallel at Google's request

MediaTek (2454 TT) is openly running a dual-track advanced packaging strategy on TSMC's CoWoS and Intel's EMIB for its cloud ASIC business, with the dual-supplier setup driven by Google's preference for back-up capacity rather than by any technical limitation at TSMC.

DigiTimes reporting confirmed that MediaTek senior management called the dual-track approach "the correct choice" at the recent earnings call. The strategy is unusual for MediaTek, which has historically anchored to TSMC's process and packaging roadmap. The hire of TSMC R&D veteran Yu Chen-hua as a part-time advisor on packaging signaled how seriously management is taking the integration challenge.

The customer driver is the most analytically important point. Google, MediaTek's anchor cloud ASIC client, is asking for a packaging alternative because CoWoS is capacity-constrained and expensive, and because TPU 8t volumes are large enough that customers want supply-chain redundancy. Whether next-generation TPU will actually ship on EMIB by 2027-2028 is still being argued inside the supply chain. EMIB cost-per-die remains attractive, but yield has not yet reached the level that beats CoWoS on total cost of ownership, and MediaTek has reportedly pulled some test wafers back onto CoWoS.

This is the 4 May Blade's "MediaTek hires TSMC's CoWoS architect" pattern, extended. Three weeks later, MediaTek's cloud ASIC team in the US is staffed primarily with senior engineers from Intel's last decade, including Vince Hu, the newly elevated senior VP for data center and compute. The Intel and TSMC bets are now structural, not exploratory.

YMTC files for June IPO with DRAM trial production by year-end

YMTC (Yangtze Memory Technologies), the Chinese NAND maker, is in the final sprint before a planned 2026 listing, with the IPO filing scheduled for June and third-phase fab production targeted for end-2026 starting with LPDDR DRAM trial output. The move pushes a state-backed challenger directly into advanced DRAM at the moment Samsung's strike and the AI memory cycle are testing global supply; it is the most concrete signal yet of Beijing's intent to break Korean memory dominance from the demand side that NVIDIA's Vera Rubin is widening.

Amazon adds NT$2.36bn to Alchip private placement at NT$4,239

Alchip Technologies (3661 TT) disclosed that anchor customer Amazon will subscribe to a NT$2.36bn private placement, taking 557,325 shares at NT$4,239 (a 15% discount to reference price), raising Amazon's stake to roughly 1% from 0.28%. Amazon's first Alchip placement, in May 2024, was NT$535m at NT$2,382 per share. This is the third major strategic placement at Alchip in 24 months, after Wistron and MediaTek's earlier rounds, and reads as Amazon doubling-down on its 3nm Trainium ASIC vehicle ahead of June volume shipment.

TI president for Asia targets 95% internal production for AI infrastructure

Texas Instruments (TXN US) is accelerating Japan and Malaysia capacity expansion with a stated 95% internal production target, according to Lee Yuan-rong, TI vice president and president for Japan, Taiwan, Korea and Southeast Asia, in a Nikkei Asia interview. The push is framed against an AI infrastructure recovery and data-center demand for analog and power semis. TI's vertical-integration target sits opposite the foundry-light model and signals confidence that AI demand for power and analog will outpace what merchant foundry capacity can supply through 2027.
