Anthropic IPO: Is ANT Stock a Buy at Launch?

The Anthropic IPO is no longer just market talk. The company filed its S-1 publicly on October 26, 2026 and followed up with an amended filing on November 2, setting out plans to list its Class A shares on the Nasdaq Global Select Market under the ticker ANT. 

Goldman Sachs and Morgan Stanley are leading the deal, but the price, the number of shares and the first trading date are all still up in the air. So the big question for investors isn’t whether Anthropic will list, but whether the final price leaves enough room for upside. 

Let’s start with where things stand right now.

Anthropic IPO’s Latest Updates

Detail	Status
S-1 filed / amended	October 26 / November 2
Earliest reported trading date	November 16 (not confirmed)
Price range, shares, offering size	Not yet announced
Latest private valuation	$965 billion
Reported IPO valuation talk	About $1.5 trillion (previously up to $2 trillion)

The roadshow was expected in the week of November 9, but that timetable is under pressure. Investors are reportedly asking for a lower valuation, and a tech and AI sell-off has made institutions more selective.

Reuters reported that about $1.5 trillion is seen as the top of an acceptable range. The $2 trillion valuation and $100 billion raise are unconfirmed, so a lower price or delay remains possible. Watch the next S-1 amendment for the price range and timetable.

Why Is Anthropic Going Public?

The main reason is capital. Training, inference, data centres, power, chips and talent are expensive, and capacity often has to be secured before the revenue arrives. By September 30, 2026, Anthropic had raised $141.1 billion in total and held $95.6 billion in cash and $36.3 billion in short-term investments, about $146.6 billion of liquidity including credit.

Against that, it disclosed about $895.4 billion of compute and infrastructure commitments. Around $447.5 billion falls before the end of 2030, including $69.8 billion in the next 12 months.

The commitments run to 2045, and about $213.8 billion carries termination rights or conditions, so this is not an immediate bill. An IPO would also give employees and early backers liquidity and set a public valuation benchmark. Still, Anthropic has raised private money easily, so it need not accept a poor public price, which is why a delay is possible.

Is Anthropic’s Price Already Too High?

The Anthropic company valuation has climbed from $61.5 billion (Series E, 2025) to $380 billion (Series G, February 2026) and $965 billion (Series H, May 2026, $65 billion raised). Trailing-12-month revenue to September 2026 is about $35.3 billion.

Valuation	Multiple of trailing revenue	Multiple of Q3 annualised revenue
$965 billion	~27.4x	~14.2x
$1.5 trillion	~42.5x	~22.1x
$2.0 trillion	~56.7x	~29.5x

The annualised column is Q3 revenue of $16.96 billion multiplied by four. It is a scenario, not a forecast. At $1.5 trillion or more, investors must believe Anthropic can keep growing fast while improving margins, cutting inference costs and funding its infrastructure. A strong company can still be a poor investment at a price that assumes perfection.

Anthropic Financials: Growth, Losses and Compute Costs

Nine-month 2026 revenue was $33.24 billion, up 1,206% from $2.55 billion a year earlier. Operating cash flow was $6.57 billion, and adjusted operating income was $4.1 billion against a $1.26 billion operating loss. Compute and infrastructure expense was $18.81 billion, about 57% of revenue, against $4.38 billion on $2.55 billion of revenue a year earlier.

Growth is slowing from a very high base. Quarterly revenue rose from $4.73 billion to $11.56 billion and then $16.96 billion, with sequential growth easing from about 144% to 47%. Anthropic swung from a $974 million operating profit in Q2 to a $567 million loss in Q3 as compute costs hit $9.86 billion.

The $104.0 billion nine-month net loss looks alarming but is mostly non-cash. About $94.3 billion came from fair-value changes on convertible notes and derivatives as the valuation rose. Positive operating cash flow is not free cash flow, though, as heavy infrastructure payments will follow.

Run-rate revenue (about $9 billion at end-2025, over $65 billion by end-July) annualises the latest 28 days and is not audited, so the S-1 figures are the firmer guide. On the customer side, over 11,900 customers spend at least $100,000, about 250 spend $10 million or more, no customer exceeds 10% of revenue, and net revenue retention is about 900% on Anthropic’s own method, which should normalise over time.

Anthropic Biggest Investors, Ownership and Governance

The Anthropic biggest investors list goes beyond Amazon and Google. GIC and Coatue led Series G, while Altimeter, Dragoneer, Greenoaks and Sequoia led Series H. Other backers include Capital Group, D1, ICONIQ, XN, Blackstone, Fidelity, General Catalyst, Jane Street, Lightspeed, MGX, Temasek and T. Rowe Price.

Amazon has invested about $8 billion plus $5 billion in Series H, with $15 billion still available under its 2026 arrangement, and AWS remains the primary cloud and training partner. Google put $10 billion into Series H, leaving $20 billion of capacity, and the two also work on five gigawatts of TPU capacity. These partners supply capital, compute and distribution, but they also compete with Anthropic and can see its pricing terms.

Governance is unusual. As a Delaware public benefit corporation, Anthropic has a Long-Term Benefit Trust that appoints a board majority. A founder-held Class F share carries 50.1% of voting power, and public Class A shares are capped at 49.9%. This protects the safety mission but limits shareholder influence.

Is Anthropic a Good Investment?

Whether Anthropic is a good investment depends on the price as much as the business.

Should You Buy the Anthropic IPO?

The buy case: 

It offers rare direct exposure to a frontier AI developer, with deep enterprise adoption, a 15% Q3 adjusted operating margin (versus negative 93% a year earlier), strong liquidity and major cloud partners.

The no-buy case:

• Valuation of 42.5x trailing revenue at $1.5 trillion, and close to 57x at $2 trillion.
• Long-dated, partly conditional infrastructure commitments.
• Competition from OpenAI, Google and cheaper open-weight models.
• Over 80% of Q3 revenue came from models released in the past six months.
• About $8.2 billion of stock-based compensation on completion, plus $24.1 billion over roughly two years, which could dilute holders.
• Limited public voting power.

Verdict: Near $965 billion the entry is more defensible, though still expensive. At $1.5 trillion there is little room for error, and near $2 trillion the no-buy case is considerably stronger. Anthropic may be an outstanding business while ANT is overpriced at launch. Cautious investors may wait for the first one or two earnings reports.

How Can You Invest in Anthropic 

If you are asking how to invest in Anthropic, note that no public market exists before the offering becomes effective, and private trades are restricted and illiquid. Once the Anthropic IPO proceeds, there are three routes to buy Anthropic stock:

1. IPO allocation: a portion is expected through Schwab, Fidelity, Robinhood, Trade-PMR, SoFi and E*TRADE, subject to platform and jurisdiction, with no guarantee of shares.
2. Buy ANT on Nasdaq after trading begins, where the price may open well above or below the IPO price.
3. Trade a CFD linked to ANT, which gives no ownership, voting rights or shareholder distributions.

There is no need to buy on day one, as new listings often see price gaps, wider spreads and volatility.

Conclusion

The Anthropic IPO is a major test of public-market confidence in frontier AI. The business case is strong, with rapid growth, deep enterprise adoption and positive operating cash flow. Yet the valuation, almost $900 billion of long-term commitments, reliance on cloud partners, fierce competition, heavy stock compensation and a governance structure that limits shareholder influence all temper the enthusiasm.

In the end, the final offer price will decide whether ANT offers a fair premium for AI leadership or asks investors to pay upfront for success that has yet to be delivered.

For traders who want to follow the listing as it unfolds, Ultima Markets plans to make ANT and ANT.24H available on MT5 around the expected market debut, initially targeting mid-November 2026. Web and App availability will be confirmed separately, and the exact launch date, trading hours and product specifications will depend on Anthropic’s final IPO schedule and Ultima Markets’ official announcement.

As ANT will be offered as a CFD, traders will not own the underlying Anthropic shares. CFDs and leverage can magnify both gains and losses, and newly listed stocks can move sharply with limited liquidity, so it pays to approach the first days of trading with care.
