Could the Swedish photonics company SIVE, strongly recommended by AI stock guru Serenity, still be revised upward?

Serenity (@aleabitoreddit), the X-platform AI analyst who called Dell's earnings-driven 28% surge, recently posted about a new target: Sivers Semiconductors ($SIVE), a small Swedish-listed company that makes indium phosphide (InP) laser chips. Its market cap has already rocketed from $150 million to $2 billion — a 13x gain. (Background: Dell earnings explode with a 28% surge: Trump bought at $126 and has already tripled, the new stock guru calls to chase the upstream supply chain) (Background context: TSMC teams up with Marvell for a knockout combo, the "2nm + silicon photonics" plan swallows global ASIC chip market share) Key Takeaways - Serenity uses a "progressive doubt" framework to dissect SIVE's four-stage short-squeeze history from $150 million to $2 billion, where every round of market skepticism was slapped down by new customers or data - SIVE is a chokepoint supplier of upstream laser light sources for silicon photonics / co-packaged optics (CPO), with customers including Jabil and Ayar Labs. Serenity calls it a potential Apple supplier - Q1 2026 revenue fell 22% YoY, but the project pipeline exploded 77% to $799 million, with Win Semi handling foundry capacity expansion Serenity, the X-platform analyst who called Dell's 28% earnings surge, nicknamed the "AI stock god," became famous in the US retail crowd for his "Chokepoint Theory." Last time he called Dell, the market laughed at him — and Dell jumped 39% after-hours when earnings dropped. This time he posted again, with a target most people have never heard of: a Swedish photonic chip company called Sivers Semiconductors (Stockholm Exchange ticker SIVE, US OTC ticker SIVEF). What SIVE makes is tiny — indium phosphide continuous-wave distributed feedback laser arrays (InP CW DFB) — but its position is critical. It's the light source for transmitting data at the speed of light between GPUs in AI data centers. > markets went from doubting $SIVE customers ($150m MC) Turns out it's likely companies eg. $JBL, Ayar, $AAPL, Defense Primes, $MRVL celestial. > to doubting their execution ($600m mc) Turns out you skip the capex if you go with Win Semi > to doubting what share they get vs… — Serenity (@aleabitoreddit) May 30, 2026 Serenity uses a "progressive doubt" framework to dissect SIVE's market-cap climb. Every price level had its own round of bearish logic, and every round got overturned by subsequent facts: At a $150 million market cap, the market questioned whether the customer list was credible. The result: Jabil officially announced using SIVE's DFB lasers in its 1.6T optical transceiver modules, and Ayar Labs' SuperNova light source explicitly states it uses SIVE laser arrays. The list also includes defense contractors, the Marvell ASIC ecosystem, and what Serenity calls a "US Fortune 100" company (which he hinted in another post is Apple, with a 50-million-unit quote request). At a $600 million market cap, the market questioned whether a small Swedish company had execution capability. The result: SIVE handed off wafer fabrication to Taiwan's Win Semi (3105.TW), skipping the capex threshold of building its own fab and running an asset-light model. At a $1.2 billion market cap, the market questioned how much share SIVE could grab and whether it would get crushed by Lumentum ($LITE). The result: Serenity points out that SIVE is Jabil's sole source light supplier and Ayar Labs' preferred supplier. In addition, SIVE has signed CPO mass-production partnerships with O-Net and Enablence, and established a strategic partnership with POET. It's not competing with Lumentum for market share — it occupies a position that Lumentum doesn't serve. At a $2 billion market cap (now), the market questions whether the revenue can actually materialize. Q1 2026 revenue was 61.9 million Swedish kronor, down 22% YoY, but the decline was mainly due to the late-2025 US government shutdown delaying defense budgets. The key number is the pipeline: the project pipeline exploded 77% from $453 million to $799 million. CEO Vickram Vathulya maintained the full-year outlook unchanged, with defense order restarts in H2 as the catalyst. Every round of bearish logic sounded reasonable, but every round tripped over "customer validation that wasn't yet public." In plain terms, what SIVE does is this: in AI data centers, data transmission between GPUs is switching from copper wires to optical fiber. Optical fiber needs light sources, and those light sources are DFB lasers. SIVE makes the chips for those light sources. In the co-packaged optics (CPO) supply chain, it's "upstream of upstream," supplying silicon photonics unicorns valued at $4–15 billion such as Lightmatter, Celestial AI, Ayar Labs, and Lightelligence. Serenity calls SIVE a "kingmaker" — none of these unicorns' light sources can bypass it. In his post, Serenity directly rebuts the current final wave of bearish argument: "Can Win Semi actually expand capacity?" His answer is blunt: "Win Semi is one of the most important compound semiconductor foundries in the world. Broadcom, Lumentum, and SpaceX supply chains all use it. If you think Win Semi can't expand capacity by 2028, you're a stupid bear." Win Semi is Taiwanese, SIVE is Swedish, and the customers are in the US. Geographic decentralization of the AI supply chain isn't a slogan — it's happening. Serenity also flagged the risks. He notes SIVE's shareholder structure has already shifted, because US retail investors have taken most of the float from Swedish investors. The issue is that US institutional investors may enter next, and the institutional playbook is often to shake out retail before pumping. He cites Nebius ($NBIS) and Rocket Lab ($RKLB) as cautionary tales — both went through violent institution-led washouts after retail loaded up, before finally opening their true super-cycles. SIVE currently trades at 68.95 Swedish kronor, about 8% off its May 22 all-time high of 74.90 kronor, with a market cap of roughly 20.7 billion Swedish kronor (about $2 billion). Short-term chips have already rotated from Europe to the US, but institutional capital has yet to enter in size. Serenity's call is that SIVE is the next Lumentum, with a personal bullish target above $10 billion. SIVE's Q1 revenue is indeed falling, and converting that $799 million pipeline into revenue will take time. The above is not investment advice. FAQ What is SIVE (Sivers Semiconductors)?
