Sivers Semiconductors frenzy: The blog that sparked the danger and the billion-pound deal that made it explode

I've been following the Swedish tech market for over a decade, and I'll be honest, I had a real sense of déjà vu on Thursday morning when trading kicked off. Sivers Semiconductors was simply everywhere. It wasn't just a rally; it was a frenzy. One of the country's largest financial newspapers reported that shares worth 200 million kronor changed hands during the morning alone – more than our national treasure, Investor, turned over in the same period. For those of you who aren't market-obsessed: these are absolutely staggering figures for a company that most people outside the tech niche still can't spell.

So, what exactly sparked the danger? Well, it actually started last Friday, when a well-known voice from the past, one that many remember from the analyst houses, stepped up to the keyboard. This person wrote a blog post that landed with a bang in trading floors across the country. His point was as simple as it was powerful: look at the valuation of US AI companies, then look at Sivers Semiconductors AB (publ), which holds the same kind of groundbreaking technology. The gap was absurd. The stock, which had been quietly simmering, caught fire and has since rocketed over 160 percent.

From blog hype to billion-pound contracts

The thing with this kind of surge is that it rarely sustains itself without substance. But here we have a company that has delivered proof point after proof point. For those willing to dig through the filings, we saw back in February that Sivers Semiconductors AB (publ) to Report Q4, 2024 Results on Feb 07, 2025, and the report was strong with positive adjusted EBITDA. Then came the next confirmation. In mid-March, it became clear that a customer in LiDAR – that's advanced laser sensor tech for cars and industry – is now moving towards scalable volumes. We're talking about a revenue potential of up to a breathtaking $138 million over the product's lifecycle, starting in the fourth quarter of this year. This isn't hype; it's serious money on the way in.

And then there's the AI angle. A couple of weeks ago, Sivers Semiconductors announced a collaboration with O-Net and Enablence to develop custom-designed light sources. Why is this important? Well, today's AI chips, like those from Nvidia, get so hot that standard lasers melt or stop working. Sivers' solution moves the light sources off the chip – it's called Co-Packaged Optics – and solves a massive headache for the entire data centre industry. The people I've spoken to point to an addressable market that could exceed $20 billion by 2036. That's the kind of thing that makes investment companies like Latour sit up and take notice.

The numbers that count right now

For those of you who like hard facts, not just feelings, here's a quick snapshot of the current situation:

• Q4 2025 showed net sales of 80.7 million kronor, an increase of 5% from the previous year.
• Growth in constant currency was a full 17% for that quarter.
• The future business pipeline grew by 64% during 2025, reaching $453 million.
• Order intake for projects and products over the coming years already stood at 234 million kronor at the turn of the year.

Sure, they're still posting a loss on the bottom line, but that's the investment phase we're talking about. The interesting part is that order intake and the pipeline are growing faster than ever. Sivers Semiconductors AB has pulled off the clever trick of having its feet firmly planted in today's contracts (like the Intelsat deal where volume deployment kicks off during 2026) while keeping its eyes firmly fixed on tomorrow's mega-trends.

What happens next?

Now we've arrived at the 20th of March, 2026. The frenzy has settled at a significantly higher level than just two weeks ago, and the question on everyone's lips is whether it's too late to jump on board. My personal experience from similar journeys is that companies like Sivers Semiconductors AB (publ) rarely go back to where they started once they've caught the world's attention. The next big milestone will be the 27th of April 2026, when the year-end report for the full year 2025 is presented. That's when we'll see if the 234 million kronor order intake has translated into even higher figures.

One thing is for sure: from being a well-kept secret among hardcore tech investors, Sivers Semiconductors is now a name that even your neighbour has heard about over morning coffee. And in this industry, attention is sometimes what breeds success. Hold onto your hats, this could be quite a ride.
