Anthropic's $2 Trillion IPO: The Bet, the Backing, and the Biggest Risks

The Revenue Story Driving the $2 Trillion Price Tag

The $2 trillion+ valuation rests on a trajectory that is extraordinary even by AI-boom standards. Anthropic's annualized revenue run rate has surged from roughly $1 billion in late 2024 to $9 billion by the end of 2025, then to $30 billion by April 2026, and $47 billion by late May 2026 . The company projects positive cash flow by 2027–2028 .

But the real anchor for the $2 trillion target is a far more ambitious figure: Anthropic is forecasting roughly $190 billion to $200 billion in annual revenue by 2028, a previously unreported figure confirmed by two people familiar with the company's financials . Wall Street is looking two years further into the future than typical IPO valuation methodology to justify the price . On a forward 2028 revenue basis, the price-to-sales multiple drops to roughly 10–10.5x, which backers argue is conservative relative to high-growth AI stocks . At the current $47 billion run rate, however, a $2 trillion valuation implies a multiple of roughly 43x current revenue .

Investors now expect annualized sales to reach between $100 billion and $120 billion by the end of 2026 — a more-than-tenfold increase across the year .

Which Public Companies Are Being Used as Benchmarks?

According to Reuters, the comparable companies being used as reference points ahead of Anthropic's analyst day are Cloudflare (NET), Palantir (PLTR), and SpaceX . Other sources note that Palantir and Nebius have traded at about 55x this year's revenue, which supporters argue makes Anthropic's ~43x multiple look reasonable .

Still, Anthropic has no comparable listed peers in the United States , making valuation inherently speculative. Fortune notes that a $2 trillion Anthropic would need to "earn like Amazon" to justify the valuation — Amazon's revenue at its $2 trillion market cap was substantially larger . Across the Nasdaq 100, the average company trades at roughly 34 times trailing earnings and 25 times forward earnings .

Skepticism: Extreme Forward-Pricing, Export Controls, and Bubble Warnings

Several concerns have been raised by analysts, investors, and central bankers:

• Extreme forward-pricing: The IPO is "pricing in an extensive amount of anticipated future success" . One investor told Reuters: "Could they get a $2 trillion valuation? Yeah, they could. I just wonder if it would stay there over time."
• Export control risk: US export controls briefly pulled Anthropic's two top models and slowed June revenue growth. Its flagship model also costs 2.5 times more to run than OpenAI's comparable model .
• Revenue retention uncertainty: The company must sustain a roughly 10x annual revenue growth rate for three consecutive years — a pace that is historically unprecedented for any company at this scale . Nearly 64% of IPOs underperform over three years, and mega-debuts like Meta's lost more than half their value before ever reclaiming the offer price .
• Bubble warnings: Senior central bankers — including the Bank of England — have warned of excess liquidity and bubble-like conditions in AI markets, noting that US equity valuations are close to the most stretched they have been since the dotcom bubble . Jim Cramer dismissed "out of hand" bubble fears, but other analysts remain cautious .
• Circular financing concerns: Some analysts question whether the rapid valuation growth reflects genuine enterprise demand or a cycle of large strategic investments — from Google and Amazon, both of whom are also customers — propping up valuations .

Prediction Markets: Anthropic Is Favored to Beat OpenAI to Market

Prediction markets strongly favor Anthropic going public first, and by a wide margin:

• Polymarket odds for Anthropic IPO by December 31, 2026: ~68–81.5%, depending on the data source and date . The October 31, 2026 cutoff carries roughly a 42–71% probability, while September 30 is at ~6–9.5% .
• Polymarket odds for OpenAI IPO by December 31, 2026: Just 19%, down sharply from a peak of 77% in early June 2026 . OpenAI filed its confidential S-1 a week after Anthropic but is reportedly leaning toward a 2027 timeline after internal deliberations on remaining private longer .
• Direct head-to-head: On Polymarket's contract for "Which company IPOs first?," the market heavily favors Anthropic, with odds often above 80% . Both prediction markets and quantitative models "overwhelmingly agree that Anthropic is most likely to IPO first" .
• Kalshi data: Shows 57% odds of an Anthropic IPO announcement before November 1, and 73% odds of a 2026 IPO overall — versus 22% for OpenAI .

The Bottom Line

Anthropic is widely expected to beat OpenAI to market by at least several quarters, with an October 2026 IPO that would be history's largest. But the $2 trillion valuation depends on the company nearly quadrupling its already enormous revenue by 2028 — and skeptics, including senior central bankers and veteran investors, question whether that trajectory is sustainable. The IPO will be the biggest test yet of whether the AI boom's private-market exuberance can survive public-market scrutiny.
