Celonis IPO: Why the Munich Unicorn Still Hasn't Listed

The Celonis IPO is Europe's longest-running listing rumour. Germany's most valuable software startup has been "next year's IPO" since at least 2021, when a $1 billion funding round crowned it a decacorn. Five years on, the Munich process-mining pioneer is still private — even as one secondary-market platform puts the probability of a listing at 95% or higher, and reports through 2026 describe a company keeping New York, London, and Frankfurt all in play.

The reasons it hasn't happened yet tell you more than the rumours: a 2022 valuation of nearly $13 billion that secondary markets have never fully believed, financials the company keeps tightly private, and a high-stakes antitrust lawsuit against SAP heading to trial in December 2026. This guide covers all of it — what Celonis does, what its shares actually trade at (and why the quotes disagree), who owns it, and how to trade the enterprise software theme while the wait continues.

Celonis IPO at a glance (September 2026):

• Status: Private. No filing, exchange, or prospectus — but widely reported as a leading 2026–27 IPO candidate.
• Last official valuation: ~$13 billion (August 2022 round).
• Secondary quotes: platforms show prices from roughly $225 to $250 per share in 2026 — and implied a valuation as low as $7.7 billion in 2024.
• Wild card: Celonis v. SAP, an antitrust and trade-secrets case with a jury trial scheduled for 7 December 2026.

What is Celonis?

Celonis is a Munich-founded software company — with dual headquarters in Munich and New York — that created and still leads the market for process mining. Founded in 2011 by three Technical University of Munich students, Alexander Rinke, Bastian Nominacher, and Martin Klenk, it began as a consulting project analysing IT service workflows and grew into what many call Germany's most valuable startup, serving well over a thousand large enterprises, including household names such as Uber, Dell, Lufthansa, and BMW.

What process mining and process intelligence mean

Every big company believes it knows how its processes work — ordering, invoicing, shipping, hiring. Process mining proves they usually don't. Celonis software plugs into the systems where work actually happens (ERP platforms like SAP, CRMs, ticketing tools), reads the digital footprints every transaction leaves behind, and reconstructs an X-ray of how processes really run — every detour, delay, duplicate payment, and rule violation included. The company's newer framing, process intelligence, extends this into a living map (its Process Intelligence Graph) that feeds optimisation and, increasingly, AI agents: before software can automate work, something has to tell it how the work actually flows. That positioning — the process layer beneath enterprise AI — is the heart of the IPO pitch.

How Celonis makes money

Celonis sells subscriptions to its cloud platform, priced by the processes, data volumes, and modules a customer deploys — classic enterprise SaaS economics with land-and-expand mechanics. A customer might start by mining its accounts-payable process, discover millions in duplicate payments, then extend to procurement, logistics, and customer service. Around the core sit consulting-partner ecosystems (the big accounting and consulting firms all build Celonis practices), an app marketplace, and execution tools that act on what the mining finds. Reported figures put annual recurring revenue at $400 million in 2021 and an estimated $771 million by 2023, growing near 40% (Getlatka); on that trajectory, analysts generally place current ARR around or beyond the billion-dollar mark, though the company does not publish figures.

Is Celonis going public?

All signs point to eventually — but Celonis itself has never formally committed. The company has been Europe's most-cited IPO candidate for half a decade; Forge Global assigns a listing probability of 95% or higher (Forge), and it features on every serious upcoming-IPO watchlist, including Markets.com's IPO calendar. Management's public posture has consistently been that an IPO is an option rather than an obligation — the company raised heavily in 2021–22 precisely so it could choose its moment. What has never appeared: a filing, a named exchange, appointed underwriters, or a prospectus. Until one does, Celonis remains a candidate, not a commitment.

Celonis IPO date: what has been reported

The reporting through 2026 sketches a window without a date:

European market watchers listed Celonis among the mega-listings expected to boost Europe's tech stock sales, with a listing "now expected for 2026" in some coverage (Trending Topics).

A May 2026 report described the company as flexible on venue — New York, London, and Frankfurt all possible — language that suggests active internal planning without external commitment.

No banks, no confidential filing, and no exchange have been announced as of September 2026.

Realistically, the December 2026 SAP trial date argues against a listing this year: companies avoid pricing IPOs weeks before a jury decides a case central to their competitive story. A 2027 window — after the litigation clarifies, win or settle — fits the facts better than the perennial "this year" chatter.

Why Celonis has stayed private

Four forces explain a decade without a ticker:

• It banked its war chest at the top. The 2021–22 rounds raised well over $1.5 billion in equity and credit, meaning Celonis has never needed public capital since.
• The valuation overhang. Its $13 billion 2022 price was set at the peak of software multiples; secondary markets spent the years since quoting it lower. Listing below your last round is painful for insiders — better to grow into the number first.
• Financial privacy is strategic. Celonis discloses almost nothing — an advantage against SAP and Microsoft that a prospectus would surrender permanently.
• The SAP fight. Since 2025, its lawsuit against the ERP giant has been both existential and unresolved; few companies list mid-litigation against their most important platform partner.

Add the quieter reason — German engineering culture's patience with private ownership — and the "still hasn't listed" mystery mostly dissolves into rational sequencing.

Celonis valuation and funding history

The 2021 round — led by growth investors including Durable Capital and T. Rowe Price — made Celonis Germany's first decacorn; the 2022 extension, with participation from investors including the Qatar Investment Authority, nudged the headline to nearly $13 billion (Forge, Contrary Research). That figure remains the official mark. Whether anyone would pay it today is exactly what the secondary market disputes — and what an IPO would finally settle. Reported banker chatter about a $15–20 billion listing valuation should be read as ambition, not evidence.

What Celonis shares are quoted at on secondary markets

Because Celonis is private, its shares change hands only in negotiated secondary transactions — and the quotes are all over the map. Nasdaq Private Market estimated the price at $225.02 per share as of 19 August 2026 (NPM); the platform Notice quotes around $250 per share (Notice); and as recently as June 2024, secondary trading implied a company valuation of just $7.7 billion — roughly 40% below the official $13 billion mark.

Why the quoted prices disagree

The disagreement is structural, and understanding it is a masterclass in private-market pricing:

• Thin, lumpy volume. A handful of negotiated trades per quarter sets the "price"; one motivated seller can move the quote 10%.
• Different share classes. Preferred stock with downside protections is worth more than common; platforms often can't distinguish which class traded.
• Stale marks. Some quotes are last-trade prices months old; others are bid/ask midpoints or model-derived estimates — three methodologies, three numbers.
• Information darkness. With no published financials, buyers price rumours; spreads widen to cover the ignorance.
• Platform incentives. Marketplaces quoting attractive prices attract order flow in both directions.

The professional read: treat the $225–250 range as a rough centre of gravity, the $7.7 billion 2024 print as evidence of how far marks can fall in bad tape, and the $13 billion official figure as a ceiling insiders hope to defend at listing. None is "the" price — that's what IPOs are for.

Celonis revenue, customers and growth

What can be said with sourced confidence:

• ARR trajectory: $400 million in 2021 → an estimated $771 million in 2023, growing around 39% (Getlatka); the company's silence since suggests the next disclosed number is being saved for a prospectus.
• Customers: well over a thousand large enterprises across manufacturing, logistics, retail, banking, and the public sector — with the world's biggest consultancies acting as a distribution army.
• The growth story for an IPO: process intelligence as the data layer for enterprise AI agents — every vendor's agents need to know how work flows, and Celonis wants to be the neutral map they all license.
• The caveat: none of the recent figures are audited public numbers. An S-1 or EU prospectus would be the first true look at margins, retention, and growth — one reason IPO investors will read it hungrily.

Who owns and runs Celonis?

The three founders remain in charge and, reportedly, in control: Alexander Rinke and Bastian Nominacher serve as co-CEOs, with Martin Klenk as chief technology officer — a rare intact founding trio fifteen years in. The investor register spans early European venture (Accel, 83North), American growth capital from the 2019–21 rounds (Durable Capital, T. Rowe Price, Franklin Templeton, Arena Holdings), and sovereign wealth via the Qatar Investment Authority's participation in 2022. Employees hold meaningful equity after years of stock-based hiring. Precise stakes are undisclosed — one more number the eventual prospectus would reveal for the first time.

Recent developments at Celonis

The defining storyline of 2025–26 is Celonis v. SAP. Filed in California federal court in March 2025, the suit accuses SAP of abusing its ERP dominance to restrict rivals' access to customer data while favouring its own process-mining product, Signavio (CourtListener, Process Excellence Network). The stakes are larger than one vendor fight: agentic AI depends on enterprise platforms granting data access to outside applications, making this a test case for the whole software industry.

Since filing: SAP agreed to a data-access ceasefire — not interfering with Celonis's data extractor while litigation runs — and Celonis withdrew its preliminary-injunction motion (Constellation Research); the judge allowed Celonis to add trade-secret claims to the antitrust complaint (MLex); Celonis has separately challenged SAP data-processing patents; and a jury trial is scheduled for 7 December 2026, with settlement talk reported around SAP. Alongside the legal front, Celonis keeps building its AI-era product story — the Process Intelligence Graph and agent integrations with the major cloud and AI platforms.

Where could Celonis list?

Three venues, three arguments. New York is the commercial favourite: Celonis is dual-headquartered there, earns heavily in the US, and its comparables (ServiceNow, UiPath) trade on American exchanges at American multiples. Frankfurt is the sentimental and political candidate — Germany's champion listing at home would be a landmark for European tech, and officials would campaign for it. London appears in reports as a dark horse, though its post-Brexit record with tech listings is thin. The May 2026 "flexible on venue" reporting suggests Celonis is genuinely undecided — or using the competition between exchanges for leverage. Recent European precedent cuts both ways: strong US debuts by European software firms argue for New York; national pride and index demand argue for home. Expect the venue announcement itself to be a tradable headline for SAP and the German tech complex.

Celonis competitors and listed comparables

• SAP (Signavio) — rival, platform gatekeeper, and courtroom adversary all at once; the single most important listed stock in the Celonis story.
• Microsoft — bundles process mining into Power Automate, the classic big-platform squeeze.
• UiPath — the listed automation comparable whose post-2021 derating is the cautionary tale Celonis bankers must argue against.
• ServiceNow — the premium enterprise-workflow multiple Celonis would love to be priced against.
• IBM — process mining via acquisition, bundled into consulting-led deals.
• Software AG's ARIS — the German legacy player, now private-equity-owned.

An eventual Celonis float would be marketed as "the process layer for enterprise AI" — priced, bulls hope, nearer ServiceNow than UiPath.

Key risks around a Celonis IPO

• No commitment exists. After five years of "next year," the base case must allow for further drift.
• Litigation binary. A trial loss against SAP — or a settlement that leaves data-access questions open — strikes at the product's foundations; even victory means months of distraction and disclosure.
• Valuation overhang. Secondary prints as low as $7.7 billion versus a $13 billion official mark mean someone's expectations must break at pricing.
• Platform dependence. Celonis mines data held inside other vendors' systems; the lawsuit exists precisely because that access can be squeezed.
• Big-tech bundling. Microsoft and SAP give away "good enough" process mining inside suites customers already buy.
• Disclosure shock. A company this private has never had its retention, margins, and concentration audited in public; prospectuses sometimes disappoint.

Can you buy Celonis shares before an IPO?

Only with accreditation, patience, and caution. Platforms including EquityZen, Nasdaq Private Market, and Forge list Celonis among their marquee names (EquityZen), but the standard private-market frictions apply in full: company approval rights over transfers, five-figure-plus minimums, fees layered through special-purpose vehicles, and quotes that — as shown above — disagree with each other by wide margins. The 2024 episode, when implied valuations sat 40% below the official mark, illustrates the real risk: buying at the wrong point of a wide, dark spread. For most traders, the listed route below offers the same thematic exposure with live pricing and the ability to exit — and our Stripe and Canva guides carry the same warning about unsolicited pre-IPO offers.

How to trade enterprise software stocks now

The Celonis theme — enterprise workflows meeting AI — trades daily through its listed ecosystem, all available as share CFDs on Markets.com:

• SAP — the direct counterparty: lawsuit headlines, Signavio wins, and settlement rumours all reprice it, and it doubles as Europe's software bellwether.
• ServiceNow — the premium workflow-automation multiple and the aspirational comp.
• UiPath — the volatile automation pure-play that moves hardest on sector sentiment.
• Microsoft — the bundler whose agent strategy frames the whole data-access fight.
• IBM — consulting-led enterprise AI exposure.
• Indices — the Nasdaq-100 for the software complex; Germany's DAX 40 carries the SAP-heavy European angle.

CFDs work long or short — useful in a story with binary catalysts like a December trial date, where SAP and the theme could swing either way on a verdict. Rehearse the setup on a free Markets.com demo account, with our leverage and margin and spread guides covering the mechanics.

How to Trade Stock CFDs on Markets.com: A Step-by-Step Guide

A stock CFD allows you to speculate on a company’s share-price movements without owning the underlying shares. You can open a long position if you expect the price to rise or a short position if you expect it to fall, where available.

You are trading a contract whose value tracks the underlying share price. Stock CFDs do not provide voting rights or direct ownership in the company. Before trading, confirm that the relevant stock CFD is available under the Markets.com entity serving your jurisdiction and review its live contract details.

Step 1: Open an Account

Create a Markets.com account and provide the requested registration information. Account and product availability depend on your country of residence and the Markets.com legal entity authorised to serve you.

Step 2: Verify Your Identity

Complete the KYC process by providing your personal details and answering questions about your trading experience, financial circumstances and understanding of leveraged products.

Step 3: Fund Your Account

Once your account is approved, open the funding section and review the payment methods available to you. Supported methods, processing times, account currencies and potential conversion costs may differ by jurisdiction.

Deposit only an amount consistent with your financial circumstances and risk tolerance. Meeting the minimum margin requirement does not necessarily mean that the position size is appropriate.

Step 4: Find a Stock CFD and Place the Trade

Search for the company name and confirm that you have selected the correct CFD instrument. Check its trading hours, spread, margin requirement, overnight financing charges and current availability before opening a position.

Set your position size and select Buy to open a long position or Sell to open a short position. Review the total market exposure, required margin and potential trading costs before confirming the order.

Step 5: Manage Your Risk

Consider placing a stop-loss at a level that invalidates your trading idea rather than selecting one based only on the margin available. A take-profit order can define the intended exit if the market moves in your favour.

Calculate the position size based on the distance to the stop-loss and the maximum cash loss you are prepared to accept. Monitor company earnings, revenue guidance, analyst updates, sector developments, interest rates and broader market sentiment.

Stop-loss orders may be affected by slippage. If a stock gaps following an earnings announcement or other major event, the position may close at the next available price rather than the selected stop level.

Final words on Celonis IPO

The Celonis IPO remains unlisted for reasons that are individually sensible and collectively frustrating: a top-of-market valuation it prefers to grow into, a war chest that removes urgency, financials it guards like source code, and a courtroom date with SAP that no banker wants inside a roadshow window. The 95% listing probabilities are probably right about the destination and habitually wrong about the arrival time. For traders, the practical opportunities are already live: SAP trades on every twist of the litigation, the enterprise-AI theme reprices weekly, and the December 2026 trial is a scheduled volatility event you can prepare for today. Build the watchlist on a Markets.com demo account, follow the case, and when the Munich unicorn finally picks its exchange, you'll already know the sector cold.

Celonis IPO FAQs

When is the Celonis IPO?

No date exists. Celonis has filed nothing and named no exchange, though secondary platforms rate its listing probability above 95% and 2026 reports describe active flexibility between New York, London, and Frankfurt. The December 2026 SAP trial makes a 2027 window more plausible than a 2026 one.

What is Celonis worth?

Officially, nearly $13 billion from its August 2022 round. Secondary markets tell a messier story: implied valuations dipped to about $7.7 billion in 2024, while 2026 platform quotes of roughly $225–250 per share sit between the extremes.

What is process mining?

Software that reads the digital traces left in enterprise systems (like SAP) to reconstruct how business processes actually run — exposing delays, duplicate payments, and rule-breaking that process diagrams miss. Celonis created the category and extends it into "process intelligence" feeding AI agents.

What is the Celonis SAP lawsuit about?

Celonis accuses SAP of abusing its ERP dominance by restricting rivals' access to customer data while favouring its own Signavio product, adding trade-secret claims in 2026. SAP has agreed not to block Celonis's data extractor while the case runs. A jury trial is scheduled for 7 December 2026.

Can I buy Celonis stock now?

Only as an accredited investor via secondary platforms such as EquityZen, Forge, or Nasdaq Private Market — with transfer restrictions, high minimums, and quotes that disagree by design. There is no public ticker.

How can I trade the Celonis theme today?

Through listed names that move on the same forces — SAP above all, plus ServiceNow, UiPath, Microsoft, IBM, and the Nasdaq-100 or DAX 40 — all tradable long or short as CFDs on Markets.com, with a demo account to practise first.
