About This Event

Before Jan 1, 2028 If X serves as lead-left underwriter on Anthropic's initial public offering in the United States before Jan 1, 2028, then the market resolves to Yes. If two or more underwriters are presented on the cover of the final prospectus as jointly occupying the lead-left position, such that no single underwriter is uppermost-and-leftmost, for example, two names sharing equal top billing, then each such underwriter's outcome resolves to $1/, the number of tied underwriters, rounded do

Current Market Outlook

Goldman Sachs is trading at 67% on Kalshi to lead-left underwrite Anthropic's IPO before January 1, 2028. That means the market considers Goldman the clear frontrunner but far from a lock. A 67% probability implies roughly 2-to-1 odds in Goldman's favor, leaving a 33% chance another bank takes the top spot or no IPO happens by the deadline.

No other specific bank has a listed contract, which itself tells you something. The market sees this as Goldman's race to lose, not a competitive field.

Key Factors Driving the Odds

Goldman Sachs has the strongest existing relationship with Anthropic. The bank led Anthropic's Series C and Series D rounds, including the $450 million Series C in May 2023 and the $7.3 billion Series D in late 2024. Lead-left underwriter roles in tech IPOs almost always go to the bank that managed the company's largest private financings.

Anthropic's last major funding round valued the company at roughly $60 billion. At that scale, the IPO would be one of the largest tech offerings since 2021. Goldman has the institutional distribution network to handle that size. Morgan Stanley and JPMorgan are the only real alternatives, but neither has the same depth of relationship.

The 2028 deadline matters. Anthropic CEO Dario Amodei has said the company is "not in a rush" to go public, but the pressure from investors who put in at a $60 billion valuation will build. The market is pricing in roughly a 50% chance of an IPO happening at all by the deadline, with Goldman getting most of that probability.

What Could Change These Odds

If Anthropic hires a second bank in a co-lead role, Goldman's probability splits. The contract resolves to $1 divided by the number of tied lead-left underwriters. So if Goldman and Morgan Stanley share top billing, Goldman's contract would pay only 50 cents per share.

A major regulatory shift in AI oversight could delay the IPO entirely. The SEC has signaled increased scrutiny of AI company disclosures. If the SEC demands more transparency around training data or model safety, that could push the timeline past 2028.

Any public disagreement between Anthropic and Goldman would crater the odds fast. These relationships are personal. If Goldman's tech banking head leaves or Anthropic's CFO changes, the probability shifts.

The current 67% price looks reasonable given the relationship strength but leaves room for the real possibility that Anthropic simply waits longer or picks a different partner.

Overview

This prediction market focuses on identifying which investment bank will secure the lead-left underwriter position for Anthropic's initial public offering (IPO) in the United States before January 1, 2028. Anthropic, an artificial intelligence company founded in 2021 by former OpenAI employees including Dario and Daniela Amodei, has rapidly emerged as a major competitor to OpenAI in the large language model space. The company is best known for its Claude family of AI models, which compete directly with OpenAI's GPT series. Anthropic has raised substantial venture capital, including a $4 billion investment from Amazon in September 2023 and additional funding from Google and other investors, bringing its total valuation to approximately $18.4 billion as of early 2024. The lead-left underwriter, also called the lead-left bookrunner, is the primary investment bank that manages the IPO process, sets the offering price, allocates shares to investors, and appears first on the prospectus cover. This role is highly coveted because it generates significant fee income and enhances the bank's reputation in the technology sector. The market resolves to Yes if a single bank occupies the uppermost-and-leftmost position on the final prospectus cover. If multiple banks share equal top billing, the payout is divided equally among them. The question matters because Anthropic's IPO could be one of the largest technology offerings in recent years, potentially raising billions of dollars and setting a precedent for how AI companies are valued in public markets. Banks like Goldman Sachs, Morgan Stanley, and JPMorgan Chase are expected to compete fiercely for this mandate, given the prestige and fees involved. The outcome also signals which banks maintain dominant relationships with leading AI startups, a sector that is reshaping global technology and finance.

Historical Context

The lead-left underwriter role has been a cornerstone of investment banking for decades. In the 1990s, tech IPOs like Netscape (1995) and Amazon (1997) were led by banks such as Morgan Stanley and Goldman Sachs, establishing their dominance in the sector. The dot-com bubble saw a surge in IPO activity, with banks competing aggressively for mandates, often leading to inflated valuations and subsequent crashes. After the 2008 financial crisis, regulations like the Dodd-Frank Act changed how banks operated, but IPO underwriting remained highly profitable. The 2010s saw a wave of high-profile tech IPOs, including Facebook (2012, led by Morgan Stanley), Alibaba (2014, led by six banks including Morgan Stanley and Goldman Sachs), and Uber (2019, led by Morgan Stanley, Goldman Sachs, and others). These offerings generated hundreds of millions in fees and solidified the reputations of lead underwriters. More recently, the IPO market for AI companies has been limited. No pure-play AI company like Anthropic or OpenAI has gone public yet. The closest precedent is C3.ai, which went public in December 2020 with Morgan Stanley and Goldman Sachs as lead underwriters, raising $651 million. C3.ai's stock has been volatile, trading between $10 and $180 since its debut. Another relevant case is the 2021 IPO of Palantir Technologies, which used a direct listing rather than a traditional IPO, bypassing lead underwriters entirely. Anthropic's decision to use a traditional IPO versus a direct listing or SPAC will affect which banks compete for the lead-left role. The timing of the IPO also matters: market conditions in 2024-2027 will influence whether Anthropic chooses to go public early or wait for a more favorable environment.

Why It Matters

The selection of lead-left underwriter for Anthropic's IPO carries significant economic implications. The fees from underwriting a large tech IPO typically range from 1% to 3% of the total offering amount. For an Anthropic IPO that could raise $5 billion to $10 billion, the lead-left bank could earn between $50 million and $300 million in fees alone. Beyond direct revenue, the mandate provides a powerful marketing tool for the winning bank, signaling to other AI startups that it has the expertise and relationships to handle their offerings. This could lead to a cascade of future business from the AI sector, which is expected to see multiple IPOs in the coming years from companies like OpenAI, Cohere, and Mistral AI. The outcome also matters for the broader financial industry. The bank that wins the Anthropic mandate will likely set the valuation benchmark for AI companies in public markets. If the IPO is successful, it could encourage other AI startups to go public, creating a wave of offerings that reshape the technology sector on Wall Street. Conversely, if the IPO stumbles due to poor underwriting, it could dampen investor enthusiasm for AI stocks. For investors, the IPO represents a chance to buy shares in a leading AI company. The lead underwriter's ability to price the offering correctly and allocate shares to long-term investors will affect retail and institutional investors' returns. Regulators, including the SEC, will also watch the process closely, as AI companies face unique risks around model safety, regulatory compliance, and intellectual property.
