Sivers Semiconductors: Social Media Frenzy, Board Renewal, and Nasdaq Ambition Collide

Swedish chipmaker Sivers surges to 17B SEK market cap despite deep losses; analysts see fair value at 6.55 SEK. Nasdaq listing push triggers board shakeup and regulatory probe.

Sivers Semiconductors trades at roughly 13 times what analysts consider fair value, yet the Swedish chipmaker is racing ahead with plans that demand greater financial discipline. The stock, which has surged from a market capitalisation of 1 billion SEK to 17 billion SEK in a matter of months, now faces a pivotal test on May 29, when the company reports first-quarter earnings under US accounting rules for the first time.

The run-up has been fuelled by an anonymous X account with 400,000 followers, turning Sivers into one of the year's most dramatic speculative episodes. The stock recently changed hands around 85 SEK, while the analyst consensus stands at just 6.55 SEK. Marlon Värnik of Exelity has publicly warned of "hot air" in the rally. The company's own numbers offer little justification: revenue for the 2025 fiscal year came in at 306.6 million SEK, but the operating loss widened to minus 177.8 million SEK, compared with a previously reported minus 141.3 million SEK. The net loss reached 222.6 million SEK. The restated figures, published on May 13, 2026, reflect an alignment with US PCAOB standards — a prerequisite for the potential secondary listing on the Nasdaq in New York that looms large in the company's strategy.

That Nasdaq ambition has prompted a board shake-up. The nomination committee proposes a five-member body that includes Joakim Nideborn, former CFO of several tech companies, who is slated to become vice-chair with responsibility for Scandinavian stakeholders. Helena Svancar, who brings over 20 years of cross-border M&A experience, also joins. Departing are long-standing members Tomas Duffy, Erik Fallstrom and Keith Halsey. The overhaul is no coincidence; Sivers is simultaneously switching its reporting framework to US standards, a move that demands greater transparency and has already triggered regulatory scrutiny.

Sweden's Economic Crime Authority, the EBM, is investigating suspected information leaks related to the Nasdaq listing plans. Against that backdrop, professional investors have taken a bearish stance. Short positions account for 7.9 percent of the free float, according to one data point, while a separate filing as of May 27 shows 7.23 percent of total outstanding shares held short. Two short sellers continue to report positions above the 0.5 percent notification threshold, although some large funds have recently trimmed their bets. The risk of a short squeeze remains on the table.

The volatility has been most pronounced on the US OTC markets, where the stock trades under the ticker SIVEF. On Wednesday, the price dropped 11.54 percent to $8.31, after closing at $9.40 the previous day. The intraday low touched $7.70. Despite the pullback, the shares have still gained nearly 82 percent over the week.

Retail investors have piled in, with some 42,000 fund savers now holding Sivers shares. The rally has lifted the OMXS Small Cap Index by 30 percent this year — against a 6 percent gain for the broader market — and Sivers has been a major driver. The company operates in the artificial-intelligence-adjacent semiconductor space, a sector that naturally stirs excitement, but the operating reality does not support a 17 billion SEK valuation.

Sivers is pinning its growth story on two engines: photonics for AI data centres and radio technology for 5G, 6G and satellite communications. The May 29 quarterly report will be the first under the new US accounting standards and a critical milestone on the road to New York. For a stock trading 13 times above what analysts deem reasonable, every number in that release will be scrutinised for signs of whether the momentum can be sustained — or whether the air is about to come out of the balloon.
