Anthropic Eyes October IPO at $60B Raise in Race With OpenAI

Anthropic PBC is weighing an initial public offering as soon as October 2026, according to multiple people familiar with the matter cited by Bloomberg AI. The discussions remain preliminary and no final decision has been made, yet the company has already approached Goldman Sachs, JPMorgan and Morgan Stanley to sound out lead-underwriter roles. Wilson Sonsini has been retained as legal counsel, a step typically taken once a listing moves from casual chatter to formal process.

A public Anthropic would face quarterly earnings pressure that could curb its willingness to publish safety research or open-source model components. The company’s Constitutional AI approach has produced some of the most detailed safety papers in the industry; investors may push for faster, closed releases. Conversely, going public could fund even larger open-data initiatives if Anthropic uses proceeds to double down on safety. Either way, the IPO sets a precedent for how frontier-model governance survives Wall Street scrutiny.

Enterprise buyers have already baked Anthropic into 2026 procurement plans on the assumption it remains venture-funded. An October IPO would convert that assumption into audited financials and a stock currency for large contracts. CIOs watching the OpenAI vs. Anthropic bake-off could see pricing power shift as both firms tap public markets for capital. The $60 billion raise implies a secondary offering large enough to fund custom enterprise deployments at Fortune 100 scale.

Bankers say a confidential S-1 could drop as early as May, kicking off a quiet period that muzzles Anthropic until road-show season. Regulatory review of its dual-class voting structure—still being negotiated—will determine how much control founders Dario and Daniela Amodei retain. If October holds, retail investors will price the firm between its last private mark of $380 billion and rumored raise size of $60 billion, creating the first live referendum on AI valuations since the 2023 boom.

In February, Anthropic closed a $30 billion funding round led by Singapore’s GIC that lifted its private valuation to $380 billion, more than doubling the September 2025 figure of $183 billion. Annualized revenue has compounded 10× for three straight years to $14 billion, according to the company. Those metrics place Anthropic alongside SpaceX and OpenAI in the trio of most highly valued pre-IPO tech firms, setting up a $3 trillion combined float that analysts warn could strain market liquidity.

Sources tell Bloomberg that the October target is partly defensive: OpenAI has signaled it may file later this summer for a late-2026 debut. Both companies fear a compressed IPO window if AI valuations soften after the 2026 election cycle. The race has already pushed Goldman and JPMorgan to reserve balance-sheet capacity for what would be the largest tech listings since Alibaba in 2014. Whichever firm lists first will set the valuation benchmark the other must beat.

Wall Street’s emerging consensus is that demand exists for a $60 billion Anthropic raise, but only if the float stays below 20 percent of shares outstanding. That math implies a $300 billion market cap at IPO, a 21 percent discount to the February private round. Key risks include compute-cost inflation—Anthropic spends roughly half of revenue on GPU clusters—and regulatory scrutiny over model-safety claims. The SEC has already queried whether “Constitutional AI” can be marketed as a material differentiator without audited efficacy data.

A public Anthropic means two things for builders: first, access to a currency (stock) for partnership deals similar to OpenAI’s recent enterprise integrations, and second, stricter rate limits on free-tier API usage as the company optimizes for per-share metrics. Expect tiered pricing to tighten and new consumption-based SKUs aimed at boosting ARPU.
