01 Running thesis

The stock thesis is closed

Confluent is no longer a standalone public company. IBM completed the all-cash acquisition on March 17, 2026. The deal paid $31.00 per share, so the old CFLT investment case has played out.

That makes the bull case and bear case different from a normal stock page. Before the close, the bull case was simple: the IBM deal would finish. The bear case was that regulators, litigation, or deal problems could stop it. The bull case won.

There is no active public-stock catalyst left for CFLT. A reader can still study Confluent as part of IBM, but there is no separate listed Confluent stock to buy or sell.

Mar 2026▲IBM completed the Confluent acquisition. The event-driven CFLT thesis closed because holders received the cash deal price.

Feb 2026→Confluent filed a 10-K/A that was mainly procedural. It confirmed the company did not plan to file an annual meeting proxy because the IBM acquisition was pending.

Feb 2026▲The 2025 10-K shifted the thesis to the IBM cash deal at $31.00 per share. Operating data still showed 114% dollar-based net retention and a 56% Confluent Cloud mix within subscription revenue.

Oct 2025▲Q3 2025 showed dollar-based net retention holding at 114%. That helped ease the worry that customer spend was still getting worse.

Jul 2025▼Q2 2025 showed Confluent Cloud reaching 56% of subscription revenue, but net retention fell to 114%. The drop pointed to cost controls and slower customer consumption.

Apr 2025▲Q1 2025 showed continued cloud progress, with Confluent Cloud at 55% of subscription revenue. Net retention stayed at 117%.

Feb 2025→The 2024 10-K confirmed the cloud shift, with Confluent Cloud at 53% of subscription revenue. It also named macro pressure, longer sales cycles, and slower consumption as real headwinds.

Oct 2024▲Q3 2024 strengthened the cloud transition story. Confluent Cloud rose to 54% of subscription revenue, while net retention stayed healthy at 117%.

02 Business model

Selling the pipes for live data

Confluent made money mainly from subscriptions to its Data Streaming Platform. The platform is built around Apache Kafka, open-source software that moves data events in real time, like payments, orders, clicks, or app updates.

Customers could run Confluent in three ways. Confluent Platform was self-managed software. Confluent Cloud was a managed cloud service on AWS, Azure, and Google Cloud. WarpStream was a bring-your-own-cloud service where Confluent managed the system but customer data stayed inside the customer’s cloud account.

The model was land and expand. A team might start with one data stream, then add more apps and teams over time. That can make the product stickier, but it also makes revenue sensitive to customer usage. If big customers slow projects or cut cloud spend, usage growth can slow quickly.

03 Product portfolio

Kafka, cloud, and control

Growth engine

Confluent Cloud

This was the fully managed cloud service for Kafka and related data streaming tools. It was the main growth engine and reached 56% of 2025 subscription revenue.

Steady

Confluent Platform

This was the self-managed version for customers that wanted to run the software in their own data centers, private clouds, or public cloud setups. It still made up 44% of 2025 subscription revenue.

Option

WarpStream

WarpStream gave customers a managed service while keeping the raw data inside their own cloud environment. It aimed to serve buyers with strict data control or cost needs.

Steady

Stream processing

Confluent helped customers process data while it moved, rather than waiting to store it first. This matters for fraud checks, order updates, personalization, and machine data.

Steady

Connect and govern tools

Connectors moved data between systems, while governance tools helped teams know what data meant and who could use it. These features made the platform more useful across large companies.

04 Business segments

Almost all subscription revenue

Subscription96%modest

Services4%flat

The mix is from the year ended December 31, 2025. Subscription revenue was $1,119.7M, while services revenue was $47.0M, so services were a small add-on rather than the core business.

05 Risk factors

What can still go wrong

No standalone CFLT shares

High impact · High odds

Confluent is no longer a public stock after the IBM acquisition closed. That means investors cannot make a new standalone CFLT investment. Any future exposure comes through IBM, where Confluent is only one part of a much larger company.

We watchNasdaq listing status and IBM disclosures that mention Confluent.

IBM integration risk

Medium impact · Medium odds

Confluent’s products now have to fit inside IBM’s sales, product, and data strategy. Integration can help if IBM sells Confluent to more large customers. It can hurt if talent leaves, product speed slows, or customers worry about lock-in.

We watchIBM commentary on Confluent retention, product roadmaps, and data platform growth.

Cloud usage slowdowns

High impact · Medium odds

Confluent Cloud depended on customer consumption. In 2025, Confluent said macro pressure led to longer sales cycles, reduced IT budgets, and slower customer consumption growth. Dollar-based net retention was 114% at the end of 2025, still positive but lower than earlier periods in the audit trail.

We watchAny IBM disclosure on Confluent Cloud usage, customer expansion, or net retention.

Open-source and hyperscaler pressure

High impact · High odds

Confluent competed with internal teams using open-source Kafka and with cloud providers that bundle their own streaming tools. AWS, Azure, and Google Cloud can price or package services in ways that make a separate vendor harder to justify. That pressure did not disappear when IBM bought the company.

We watchCustomer wins, pricing comments, and signs that cloud providers are taking streaming workloads.

Profit history and spending needs

Medium impact · Medium odds

Confluent had a history of GAAP operating losses as a public company. Growth required heavy spending on product, cloud infrastructure, and sales. Under IBM, the key question is whether the business can keep growing while becoming more profitable.
