Blue Lagoon, the geothermal spa that formed from a power plant's wastewater, is going public on Nasdaq Iceland on November 20, 2026 — three years after a volcanic eruption forced it to evacuate and nearly derailed the listing entirely.
Blue Lagoon Corp. published its IPO prospectus on November 5, 2026, aiming to raise roughly €100 million at an implied valuation near €600 million. This deep dive covers what the company actually operates beyond the famous milky-blue pool, how it makes money, the capital history from a shelved 2023 listing attempt through today's offering, the Grindavík volcanic crisis that very nearly ended it, leadership, the competitive field against a rival that is already publicly traded, and what remains genuinely unresolved about the deal.

What Blue Lagoon Actually Does
The lagoon itself is not a built attraction — it is geothermal seawater runoff from the Svartsengi power plant that pooled in the surrounding lava field in the 1970s. Silica in the water sealed the lava bed, and locals began bathing in the warm, mineral-rich pool around the early 1980s. Dr. Grímur Sæmundsen, a Reykjavík physician, formally established the operating company, Blue Lagoon hf., in 1992, turning an accidental byproduct of power generation into Iceland's best-known tourist attraction.
Today the company is more than the pool: it runs the Blue Lagoon spa, the Silica Hotel, and The Retreat Hotel on-site; a skincare product line sold on-site and online; and, following two 2026 acquisitions, a broader Icelandic tourism group that includes Arctic Adventures (adventure-tour operator) and a majority stake in Norðurböð hf., which holds Jarðböðin (the Mývatn Nature Baths, rebranded Earth Lagoon Mývatn in 2025) and Sjóböðin in Húsavík. CEO Sigríður Margrét Oddsdóttir told the Financial Times, as relayed by TechNews/CNA, that the lagoon is "the world's most iconic, known for healing" but that the company now covers far more than that.
How Blue Lagoon Makes Money
Spa admissions and packages
Entry tickets, tiered packages (Comfort, Premium, Retreat Spa), and treatments remain the core of the business, drawing a reported ~1 million guests a year to the Grindavík site.
Hotels on-site
The Silica Hotel and The Retreat Hotel sell overnight stays alongside the lagoon itself, extending the average spend per visitor beyond a single day entry.
Skincare products
A branded skincare line, developed from the lagoon's silica, algae and mineral content, is sold at the site and through the company's own retail channel.
Arctic Adventures and the Mývatn/Húsavík baths
The 2026 acquisition of tour operator Arctic Adventures and the increased stake in Norðurböð hf. (Mývatn Nature Baths, Sjóböðin) diversify revenue beyond the single Grindavík site into guided tours and two additional geothermal bathing destinations.
Ownership and Capital History
Blue Lagoon has never raised venture capital in the startup sense; its capital history is a series of private stake sales, a shelved listing attempt, and now a public offering nearly a decade in the making.

|---|---|---|
| Jul 2017 | HS Orka fields offers for its 30% stake in Blue Lagoon | ~$286M implied company value (ISK 30B) |

Blue Lagoon increased its stake in Norðurböð, which holds Jarðböðin (Mývatn Nature Baths, rebranded Earth Lagoon Mývatn in 2025) and Sjóböðin in Húsavík, to more than 80%, pending Icelandic Competition Authority approval.
Planned mountain and glacier resorts
A ~€130 million mountain-resort destination targeted to open in 2028, and a second destination near a glacier tentatively planned for 2029-2031 — both described by reporting as plans, not completed investments.
Built From Wastewater, Nearly Erased by a Volcano
Blue Lagoon's origin story — an accident of geothermal engineering that became a billion-dollar-adjacent tourist brand — makes its closest brush with disaster almost poetic: the same volcanic geology that created the lagoon also nearly destroyed it. Starting at midnight on October 25, 2023, the Reykjanes Peninsula experienced a swarm of earthquakes as magma moved beneath the surface near Grindavík and the Svartsengi power plant. The Blue Lagoon closed on November 9, 2023, and the town of Grindavík was evacuated the next day, with ground cracks opening in and around the town.
Iceland's Parliament passed emergency legislation on November 13, 2023 to fund lava barriers — eventually built up to three stories tall — around Svartsengi and the lagoon itself. The Blue Lagoon reopened on December 17, 2023, only to close again the next day when an eruption began roughly 3km from Grindavík. A further eruption on February 8, 2024 again forced an evacuation and closure, with lava cutting the main access road, before the company said the site would stay shut through at least February 13, 2024. Disruptions continued intermittently before easing by roughly mid-2025.
Through all of it, the lagoon's own pool and core buildings were not damaged — the barriers held around the facility even as lava destroyed homes elsewhere in Grindavík. That the company shelved its first IPO attempt in 2023 specifically because of this crisis, then relaunched it in 2026 once the eruptions eased, is the clearest evidence of how directly tied Blue Lagoon's fortunes are to the ground it sits on.

Competitive Landscape
Blue Lagoon's most direct rival is Sky Lagoon, a newer geothermal lagoon near Reykjavík that opened in 2021 and is already part of a publicly traded company — the reverse of Blue Lagoon's own path to the public markets. Blue Lagoon's other historical domestic comparison, the Mývatn Nature Baths, is becoming less a competitor than an affiliate: Blue Lagoon now holds a majority stake in the company that owns it.
| Attribute | Blue Lagoon | Sky Lagoon |
|---|---|---|
| Opened / founded | Lagoon formed 1970s; company founded 1992 | Opened May 1, 2021 |
| Location | Grindavík, Reykjanes Peninsula | Kársnes, Kópavogur, near Reykjavík |
| Ownership | Privately held; going public Nov 2026 | Pursuit Attractions and Hospitality, Inc. (NYSE: PRSU) |
| Public market status | IPO subscriptions Nov 10-13, 2026; first trading ~Nov 20 | Already trading (via Viad Corp's Dec 2024 rename to Pursuit) |
| Annual visitors | Reportedly ~1 million guests | Not separately disclosed |
| 2026 revenue (entity/segment) | €174M guided (stand-alone) | Not broken out separately by parent |
| Recent expansion | Arctic Adventures acquisition; majority Mývatn/Húsavík stake; mountain and glacier resorts planned | Skjól ritual expansion opened August 22, 2024 |
How we counted: company and advisor announcements (Blue Lagoon) and public filings/press coverage (Pursuit/Sky Lagoon), as of November 2026. Sky Lagoon's standalone financials are not disclosed because it sits inside Pursuit's consolidated attractions segment.
Leadership Team
Sigríður Margrét Oddsdóttir — Chief Executive Officer
Took over as CEO effective March 16, 2026, succeeding founder Grímur Sæmundsen. She previously served as CEO of Lyfja hf., an Icelandic pharmacy chain, and has been described as having more than two decades of executive management experience in Icelandic business.
Dr. Grímur Sæmundsen — Founder and Chairman
A Reykjavík physician who formally established Blue Lagoon hf. in 1992 and led the company as CEO for more than three decades before the March 2026 leadership change. He reportedly remains one of the company's largest individual shareholders, per a 2022 ownership report, and moved into the chairman role.
Bull Case / Bear Case
The Bull Case
- +Reported company value has grown from roughly $286M in 2017 (an implied figure from a 30% stake sale process) to roughly €600M in 2026 private transactions — a large increase even allowing for the currency difference and the decade gap.
- +Two 2026 acquisitions (Arctic Adventures, the Norðurböð/Mývatn and Húsavík baths stake) diversify the business beyond a single geothermal pool into a broader Icelandic tourism group.
- +The 2026 revenue and margin guidance (€174M revenue, ~23% operating margin) describes a business that is already profitable, not a pre-revenue story needing a listing to survive.
- +Per TechNews/CNA's framing of Financial Times coverage, Blue Lagoon would be Iceland's only listed tourism group on Nasdaq Iceland — a scarcity position for domestic retail and pension-fund investors.
- +The company's own facilities survived a direct, multi-year volcanic crisis without catastrophic damage, demonstrating real operational resilience on a site many assumed was uninsurable.
The Bear Case
- -The headline ~€600M valuation is the Financial Times' own estimate derived from two private deals whose structure hasn't been fully disclosed — it is not the IPO's own priced valuation.
- -The €130M mountain resort and the glacier-area resort are, in the words of one Icelandic financial commentator, "plans, not completed investments," meaning a large share of the forward growth story is still unbuilt.
- -The increased Norðurböð/Mývatn stake remained subject to Icelandic Competition Authority approval as of early November 2026 — the deal was not yet fully closed at the time the prospectus was published.
- -The business sits in an active volcanic zone: the Reykjanes eruptions forced repeated closures between November 2023 and early 2024 and directly caused the company to shelve its first listing attempt.
- -Several specific offering terms (the ISK 95 share price, the 150 million share count) trace only to secondary Icelandic/European financial-press summaries, not a directly verified prospectus excerpt.
Where We Could Be Wrong
The ~€600M valuation and the ISK 95-per-share, 150-million-share offering structure both trace back to secondary Icelandic and European financial-press reporting on the Financial Times, not a directly read prospectus; the audited prospectus itself is the authoritative source once accessible.
Employee headcount is reported as 700 by one outlet (tied directly to the disclosed stock-option plan) and roughly 800 by another; we use 700 as the better-sourced figure, but neither comes from an audited company disclosure.
The 2022 ownership breakdown (~94% held by Sæmundsen, Blávarmi, and Stoðir) is four years old at the time of this IPO and may no longer reflect the current cap table.
IPO Outlook
Blue Lagoon's listing is already in motion, not a rumor: the prospectus was published November 5, 2026, subscriptions ran November 10-13, and Landsbankinn, the bank running the offering, expects results by November 16, payment by November 18, and trading on the Nasdaq Iceland Main Market to begin no later than November 20, 2026. That makes the open question not whether Blue Lagoon goes public, but what it is actually worth once trading starts and how much of its forward growth story — the mountain resort, the glacier resort, the Norðurböð approval — is still unrealized at listing.
An Icelandic financial commentator writing in mbl.is on November 2, 2026 compared buying into the offering to "buying a stake in the pyramids" — a skeptical framing aimed squarely at the gap between the lagoon's iconic brand and the amount of the company's 2026-and-beyond growth that still depends on unbuilt resorts and a regulatory approval that had not yet landed when the prospectus went out. Whether retail and pension-fund demand validates the ~€600M figure, or prices the stock below it, will be an early real-world test of what Iceland's attraction-turned-tourism-group is actually worth to public investors.
Bottom line: Blue Lagoon turned geothermal power-plant runoff into Iceland's best-known tourist brand, survived a volcanic crisis that shelved its first IPO attempt, and is now listing on Nasdaq Iceland at a roughly €600 million implied valuation while guiding to €174 million in 2026 revenue. The expansion into Arctic Adventures and the Mývatn/Húsavík baths shows real ambition to become a diversified Icelandic tourism group rather than a single attraction — but a pending antitrust approval, two unbuilt resorts, and offering terms sourced mostly from secondary press mean the real test of this listing starts only once trading opens on November 20, 2026.
All financial figures are based on publicly reported data, company and advisor announcements, and credible media reporting as of November 2026. Blue Lagoon is privately held pending its IPO and does not yet publish audited public financials; several figures cited here (headcount, specific offering terms) rest on secondary press reporting that could not be independently verified against a primary prospectus document.
