Cooley Launches GO Public With OpenAI to Bring AI Into IPO Preparation

The landscape of capital markets legal practice underwent a significant shift this month as law firm Cooley announced the rollout of GO Public, an AI-powered platform developed in direct collaboration with OpenAI. This initiative represents a departure from the industry’s initial experimentation with general-purpose chatbots, opting instead for a highly specialized, agentic workflow designed to streamline the notoriously document-intensive process of drafting Form S-1 registration statements. By integrating Cooley’s proprietary drafting principles with the computational power of OpenAI’s advanced models, the firm aims to transform how companies navigate the transition from private entities to publicly traded corporations.
The launch of GO Public marks a milestone in the "automation of expertise" within the legal sector. Rather than replacing the human attorney, the platform functions as an AI-driven force multiplier. The system ingests client-specific data and converts it into a structured, bespoke S-1 draft, which is then refined iteratively as transaction terms evolve. This process—once a laborious, manual exercise involving hundreds of hours of associate time—is now being repositioned as a predictable, high-speed, and technologically bolstered workflow.
The Evolution of IPO Preparation: A Chronology
To understand the significance of GO Public, one must examine the timeline of Cooley’s digital evolution. For decades, the legal industry operated on a traditional "billable hour" model centered on manual drafting and human-led document review. In February 2025, Cooley introduced its initial IPO GO resource, a web-based repository of information designed to guide startups through the complexities of going public. While that iteration provided valuable institutional knowledge, it remained a static resource—a map for the journey rather than the vehicle itself.
By September 2026, the firm evolved this concept into a functional, active engine. The partnership with OpenAI allowed Cooley to move beyond informational support into the realm of generative execution. As an official design partner for OpenAI, Cooley’s lawyers worked alongside AI engineers to codify the firm’s specific drafting styles, risk-mitigation strategies, and regulatory interpretations into a series of interconnected AI agents. This transition from a "resource" to an "AI-enabled offering" reflects the broader industry trend of law firms evolving into technology-forward service providers.

The Architecture of GO Public: How the System Functions
The core value proposition of GO Public lies in its focus on "structured drafting." The system is not a standalone chatbot that users prompt from scratch; it is a specialized workflow environment built on top of ChatGPT Enterprise. The workflow operates through three primary pillars:
- Input Consolidation: The system begins by gathering foundational information about the client—financial statements, business models, risk factors, and capitalization tables. This information acts as the "source of truth" for the AI.
- Agentic Drafting: Guided by Cooley’s established drafting principles, AI agents generate the preliminary S-1 filing. These agents are programmed to adhere to SEC disclosure requirements and the firm’s internal standard for high-quality, defensible legal prose.
- Iterative Synchronization: IPOs are dynamic; deal terms, market conditions, and regulatory feedback change rapidly. GO Public allows for coordinated updates across the entire document suite. If a key term changes in the business description section, the system is designed to propagate that change across the relevant legal disclosures, maintaining consistency throughout the filing.
Throughout this process, the "human in the loop" remains a non-negotiable requirement. Cooley has been clear that substantive legal judgment—the ability to identify nuance, assess potential litigation risks, and negotiate complex terms—remains firmly in the hands of the firm’s partners and associates. The AI serves to eliminate the "heavy lifting" of the first draft, allowing lawyers to spend their time on higher-value advisory tasks.
Market Implications and Industry Context
The introduction of GO Public arrives at a time of increased scrutiny regarding the use of AI in professional services. Many law firms have approached AI with caution, fearing the risks of "hallucinations" or data leaks. By opting for a controlled, firm-specific deployment with OpenAI, Cooley is positioning itself to mitigate these risks while simultaneously capturing efficiency gains.
Market analysts suggest that this move could force a recalibration of legal fees for IPO work. Traditionally, the billable hour has been tied to the sheer volume of time required to draft and edit complex filings. If AI can reduce the time required to reach a "first draft" by a significant margin, firms will need to adjust their pricing models to reflect the value of the outcome rather than the time spent on the process. While specific pricing details for GO Public have not been disclosed, the industry is closely watching to see if this model leads to a shift toward fixed-fee or value-based billing structures for capital markets transactions.
Furthermore, the success of GO Public may serve as a blueprint for other legal practice areas. The methodology—identifying a repeatable, high-stakes workflow, embedding institutional expertise into an AI engine, and retaining human accountability—is applicable to mergers and acquisitions, private equity financing, and complex litigation discovery.

Challenges and Open Questions
Despite the excitement surrounding the launch, several critical questions remain unanswered. The legal community and prospective clients are waiting for clarity on:
- Data Security and Privacy: How does the system handle the highly sensitive, non-public information of companies on the verge of an IPO? Cooley has emphasized the use of enterprise-grade security, but the granular details of data segregation remain a point of interest for corporate legal departments.
- Integration Capabilities: The ability to move data from a client’s internal systems (such as their ERP or financial software) directly into the GO Public interface will be a major factor in the system’s adoption. Seamless integration remains the "holy grail" of legal tech.
- Regulatory Acceptance: While the AI is trained on SEC standards, the regulators themselves are only beginning to grapple with the implications of AI-drafted filings. The long-term reliability of the system under the scrutiny of the SEC’s review process will be the ultimate test of its efficacy.
Broader Impact on Professional Services
The launch of GO Public underscores a fundamental change in the nature of expertise. Professional service firms are essentially repositories of knowledge. For decades, that knowledge was locked in the minds of practitioners and the pages of paper precedents. Today, firms are beginning to realize that the most valuable asset they own is their "process"—the specific way they handle a task to ensure quality and compliance.
For companies outside of the legal sector, the lesson provided by the Cooley-OpenAI collaboration is clear: AI is most effective when it is deeply integrated into the operational DNA of a business. A generic AI assistant may provide inspiration or simple summarization, but a workflow-specific AI system provides the reliability and precision required for mission-critical operations.
As the legal industry continues to adopt these tools, the distinction between a "lawyer" and a "legal systems architect" will begin to blur. The most successful firms of the coming decade will likely be those that can successfully blend deep legal domain expertise with the capacity to build, refine, and trust automated workflows.
Conclusion
Cooley’s launch of GO Public is more than just a new product announcement; it is a clear statement of intent. It confirms that the future of elite legal work lies at the intersection of human judgment and machine-assisted drafting. By formalizing its partnership with OpenAI, Cooley has taken a decisive step toward setting the standard for how capital markets transactions will be managed in the age of artificial intelligence. While the system is still in its early stages and many operational details remain to be seen, the path forward is clear: the integration of AI into the legal workflow is no longer an experimental curiosity, but a central component of high-stakes corporate practice. As the technology matures, it will undoubtedly influence the speed, cost, and structure of the IPO process, marking a permanent shift in how legal counsel is delivered and consumed.
