Assemble publicly reported Anthropic annualized revenue run-rate figures over time…

Anthropic’s private marks have not gotten more expensive. From the March 2025 Series E to the May 2026 Series H, the post-money price rose about 16x ($61.5 billion to $965 billion) while the company-stated run rate rose about 47x (roughly $1 billion to $47 billion). The implied valuation-to-run-rate multiple compressed from the high-40s/50s into the low-20s. Later investor updates pushed the run rate to $65 billion by the end of July 2026 and, per the New York Times, past a $100 billion pace by mid-September — which would put the stale $965 billion mark under 10x, and a discussed $2 trillion IPO price back around 20–31x depending on which revenue snapshot you use.

The mechanism is simple and easy to misuse: in this market the price has roughly tracked the latest monthly annualization, not trailing GAAP sales. That is why a 16x valuation jump can still look like “multiple compression.”

1. Marks matched to run rate

Figures below use post-money primary prices unless noted. Multiples are valuation divided by the run rate disclosed at or immediately around the mark. They are not enterprise-value / next-twelve-months multiples.

Date	Transaction	Price	Run rate used	Implied multiple	Confidence
Mar 3, 2025	Series E, $3.5B, Lightspeed-led	$61.5B post	~$1B at the start of 2025; press at the time used a figure that implied ~58x	~47–62x; contemporaneous press 58x	Valuation high. Run rate medium: company later said ~$1B at the start of 2025; VentureBeat’s 58x implies they used a bit above the December 2024 $1B print after a reported ~30% rise in the first two months
Sep 2, 2025	Series F, $13B, ICONIQ-led	$183B post	Over $5B in August 2025 (company)	≤36.6x	High. Both numbers are in Anthropic’s own announcement
Feb 12, 2026	Series G, $30B, GIC/Coatue-led	$380B post; $350B pre (FT)	$14B (company)	27.1x post / 25.0x pre	High
Late Feb 2026	Employee tender, $5–6B lined up	~$350B (pre-money level of the Series G)	$14B	~25x	Valuation medium (Bloomberg sources; terms not company-confirmed). Run rate high
Apr 6–20, 2026	No closed round. Company confirmed the run rate in compute-deal posts. Press reported investor offers near $800B	Offers, not a clearing price	Surpassed $30B, up from ~$9B at end-2025 (company)	~27x if an $800B offer is taken at face value	Run rate high. Price low — offers, not a close
May 28, 2026	Series H, $65B	$965B post	Crossed $47B earlier that month (company)	20.5x	High
End-Jul 2026	Investor update, no new primary	Last primary still $965B. Separate IPO talk around $2T	$65B	14.8x on the stale primary; ~30.8x on a $2T talk price	Run rate high (Bloomberg, CNBC, Reuters, all citing the investor update). $2T is a reported target, not a transaction
Mid-Sep 2026	No new primary. NYT, via Bloomberg/Axios	Same stale marks	More than $100B annualized pace expected this year	~9.7x on $965B; ~20x on $2T	Medium. “People familiar,” company declined comment. “This year” is ambiguous between exit run rate and a full-year projection

Company posts that anchor the run-rate ladder: Series F (start-2025 ~$1B, August 2025 over $5B), Series G ($14B), the April 6 and April 20 compute announcements (over $30B, versus ~$9B at end-2025), and Series H ($47B). The July $65B figure is an investor update, not a blog post, but three outlets confirmed it independently. The September “over $100B” figure is one step weaker.

A cross-check that the May multiple is not just a one-month spike: preliminary Q2 2026 revenue was more than $11.5 billion, so annualizing the quarter gives more than $46 billion. $965 billion / $46 billion is about 21x — essentially the same as 20.5x on the May monthly run rate. By late spring, the monthly and quarterly pictures had converged. They had not converged in 2025.

2. Why “run rate” and “revenue” are different numbers

Anthropic’s own metric, as Reuters and Bloomberg describe it, annualizes a short recent period — typically the latest month times 12. It is not contracted SaaS ARR, and it is not GAAP revenue. During this ramp the gap is large enough to change the multiple by a factor of two.

• Draft IPO filing, reported by Reuters on September 29, 2026: 2024 recognized revenue about $386 million; 2025 recognized revenue nearly $4.6 billion (about 12x). PitchBook/Morningstar, using the same filing, has the same pair and adds Q1 2026 revenue of $4.73 billion and preliminary Q2 above $11.5 billion.
• Exit-2025 run rate was about $9 billion (company, restated in April 2026 posts; Bloomberg, January 21, 2026). So the year-end run rate was roughly 2x what the company actually booked in 2025.
• CNBC’s August 17 piece said the company generated “roughly $10 billion” for all of 2025. That conflicts with the prospectus figure of ~$4.6 billion and looks like a run-rate/booked mix-up. The filing wins.
• Q1 2026 booked revenue ($4.73 billion) already exceeded all of 2025. That is the signature of a curve so steep that any trailing-twelve-month multiple is a historical artifact.

There is a second definitional fight, and it is not resolved. In an April 13, 2026 internal memo reported by The Verge and covered by PitchBook and others, OpenAI’s then chief revenue officer, Denise Dresser, argued Anthropic grosses up Amazon and Google revenue-share, and that this overstated a then-cited ~$30 billion run rate by about $8 billion (implying ~$22 billion on OpenAI’s net basis). The New York Times later noted that OpenAI has disputed Anthropic’s revenue calculations. Bloomberg has also said the two firms may not measure run rate the same way.

The prospectus cuts against a claim that gross-up is most of the story, at least for 2025. Reuters’ reading of the filing: about $3.8 billion of 2025 revenue was usage-based and $789 million was subscription; 47% of sales ($2.16 billion) went through Amazon and Google cloud marketplaces; distribution fees were about $351 million (Reuters’ analysis, roughly 16 cents per marketplace dollar, or ~8% of total 2025 revenue). Both gross and net treatments can be GAAP-compliant. They are not comparable across labs, and an $8 billion gap on a $30 billion headline is an adversary’s analysis, not an audited adjustment. Treat cross-lab “who is bigger” rankings as medium confidence until both S-1s use the same basis.

A third trap: much of this revenue is consumption, not recurring seats. The filing says Anthropic expects consumption-based revenue to remain “the substantial majority.” Calling the metric ARR imports SaaS stickiness the contracts do not have. Two unnamed customers each supplied about 12% of 2025 revenue, and the company warned that many large customers are not on long-term commitments.

3. API versus consumer, and what Claude Code actually is

This is an enterprise token business with a coding wedge, not a ChatGPT-style consumer company.

• At the February 2026 Series G, the Financial Times reported that about 80% of the $14 billion run rate came from enterprise customers. Reuters had the same 80% business mix in October 2025, when the run rate was approaching $7 billion and the internal year-end target was $9 billion.
• The 2025 filing split — usage-based ~$3.8 billion versus subscription $789 million — is about 83% / 17%. That is recognized revenue, not run rate, and it predates the 2026 acceleration. Directionally it matches the 80% enterprise figure.
• Claude Code, generally available in May 2025, is the product the company cites as the breakout, but company-confirmed dollars show it as a mid-teens share, not the majority:
  • September 2, 2025: over $500 million run rate (company), against a total above $5 billion → about 10%.
  • October 2025: nearly $1 billion, per a Reuters source, not a company blog line.
  • February 12, 2026: over $2.5 billion, more than doubled since the start of 2026; business subscriptions had quadrupled; enterprise was more than half of Claude Code revenue (company and Reuters). Against a $14 billion total, that is about 18%.
• Later Claude Code figures in the $8–15 billion range (May–August 2026) come from analyst and alt-data writeups, not Anthropic. Do not use them in a multiple. The economically important point is the one the company does state: Claude Code pulls engineering teams in, and the bulk of dollars still clear as API and enterprise usage, including through Bedrock and Vertex. Marketplace distribution was 11% of revenue in 2023, 32% in 2024, and 47% in 2025.

4. OpenAI, xAI, and public software

OpenAI has been marked at a higher multiple on a slower, more consumer-heavy curve — and that gap has closed as its own run rate caught up.

• March 31, 2026: $122 billion raised at an $852 billion post-money valuation. The company said it was generating $2 billion a month (about $24 billion annualized); the New York Times later described a March implication of about $24 billion. That is roughly 35.5x. At the same moment Anthropic’s February mark was 27x on $14 billion, and six weeks later Anthropic’s Series H was 20.5x on $47 billion.
• August 2026: Bloomberg reported OpenAI’s run rate above $40 billion, while an August employee tender held the price at $852 billion. Implied multiple about 21x — in line with Anthropic’s May primary, and richer than Anthropic’s stale $965 billion mark on the July $65 billion update (~15x).
• September 29, 2026: Reuters, confirming Axios, said OpenAI’s annualized revenue was approaching $70 billion, up more than 70% since the start of the third quarter, with enterprise sales more than doubling since July and Q3 consumer revenue exceeding all of 2025 consumer revenue. Early-October reports had OpenAI in talks to raise at least $30 billion at about a $1.4 trillion pre-money valuation. If both figures held, that would be about 20x — the same neighborhood as a $2 trillion Anthropic IPO on a $100 billion pace. Neither round has closed.
• Mix contrast: Anthropic is ~80% enterprise/API. OpenAI’s historical mix was consumer-led (ChatGPT); by mid-2026 enterprise was described as more than half of revenue in some estimates, but the September Reuters note still shows consumer as a large incremental engine. Weekly users remain an order of magnitude apart. Revenue leadership and user leadership are different businesses.

xAI is not a useful run-rate comp unless you specify which revenue you mean.

• January 2026 Series E: $20 billion at a $230 billion valuation; the February SpaceX acquisition marked xAI at $250 billion.
• SpaceX’s IPO filing, reported by TechCrunch on May 20, 2026: the AI segment (Grok, X, and compute/infrastructure, not a pure model API) did $3.2 billion of revenue in 2025 and lost $6.4 billion from operations. On that segment number, $230 billion is about 72x trailing segment revenue. On narrower estimates of standalone Grok product revenue near $500 million, the multiple is several hundred times. Those are different businesses stuffed into one label. Q2 2026 AI-segment revenue of $2.56 billion (later SpaceX reporting) annualizes near $10 billion — still a different object from Anthropic’s Claude run rate.

Public software, as of late summer 2026, does not underwrite a 20x multiple on trailing sales. It can underwrite something in that range only for the fastest growers on forward revenue — and even they are not growing like this.

• Scalar’s September 2026 software index, EV / next-twelve-months revenue: Palantir 43.3x (64.7% NTM growth), CrowdStrike 35.0x (23%), Cloudflare 33.2x (29.7%), Snowflake 17.5x (28.3%), Datadog 16.5x (24.4%). The high-growth cohort (NTM growth above 20%) averaged 10.3x. In August the same high-growth cohort was 9.6x, with Palantir at 33.6x NTM.
• Windsor Drake’s August 21, 2026 public AI set: median 15.0x EV / trailing revenue (interquartile 9.3x–23.8x); AI application software 11.1x; Palantir 68.7x trailing on ~93% growth and ~85% gross margin. A broader SaaS set the same date had a median near 4.9x trailing.
• SaaSDB’s Q2 2026 public SaaS screen: median 4.8x EV / trailing revenue; Palantir 75.3x trailing; Snowflake 21.5x.

Palantir is the only large public software name whose forward multiple sits above Anthropic’s May run-rate multiple, and it earns that with software gross margins and positive operating margin. Anthropic’s Q2 2025 gross margin is not in the draft filing excerpts that have been reported; compute was $7.33 billion in 2025 against $4.6 billion of revenue, and operating loss was about $8 billion. A 20x run-rate mark is a bet that consumption growth continues and that gross margin inflects — PitchBook’s October 2, 2026 note puts a $2 trillion price at about 435x 2025 revenue, under 44x annualized Q2 2026 revenue, and just under 31x the July run rate, and says that price still needs margin improvement the filing has not established.

5. How to use this if you are pricing the IPO or competing

The stable object in this tape is not the multiple on trailing sales. It is a willingness to pay roughly 20–30x the latest monthly annualization, then let the next quarter re-rate the denominator. Series G (27x), the April offer chatter (~27x), Series H (20.5x), a $2 trillion talk price on the July print (~31x), and a $2 trillion talk price on a $100 billion pace (~20x) all sit in that band. OpenAI’s March 2026 mark was the outlier on the high side (35x) and has since compressed toward the same band as its run rate caught up.

Three adjustments matter more than another headline:

1. Haircut the run rate to a booked-revenue equivalent if growth slows. In 2025, exit run rate was ~2x full-year GAAP. If 2026 growth decelerates, a $65–100 billion July/September pace will not become $65–100 billion of recognized 2026 revenue. Q1 plus Q2 already imply a second-half hurdle: $4.73 billion + $11.5 billion = $16.2 billion through June, so a $65 billion year would require ~$49 billion in the second half.
2. Do not compare Anthropic gross marketplace revenue to OpenAI net Azure revenue. The 2025 fee drag was hundreds of millions, not the majority of sales, but at a $65 billion pace even an 8% marketplace haircut is about $5 billion. OpenAI’s $8 billion claim was larger than the 2025 fee ratio and should be treated as a negotiating position until the S-1 accounting policy is public.
3. Claude Code is the wedge, not the P&L. Company-confirmed share went from ~10% (September 2025) to ~18% (February 2026). The dollars that reprice the company are still API and enterprise consumption, concentrated in a small number of buyers and in two cloud partners who are also investors, suppliers, and competitors. That concentration is the risk a 20x run-rate multiple does not price, and it is why a coding-tool competitor can move Anthropic’s growth rate without matching its headline revenue.

Confidence summary: primary-round valuations and the company-stated run rates at Series F, G, the April compute posts, and Series H are high. The July $65 billion update is high for a private figure (three independent outlets, investor documents). The September $100 billion pace and any $2 trillion IPO price are medium. Claude Code above $2.5 billion is estimate-grade. Any multiple that uses 2025 GAAP revenue against a 2026 valuation, or that ranks Anthropic against OpenAI without a gross/net bridge, is not a like-for-like sales multiple.

Recent Findings Supplement (October 2026)

Anthropic’s revenue run-rate accelerated sharply after its May 2026 Series H round, reaching ~$65B annualized by late July 2026 (up from $47B in May), driven by enterprise/API usage and Claude Code, while its valuation climbed from $380B (Feb) to $965B (May) with IPO targets exceeding $2T.[1][2]

This growth outpaced OpenAI’s reported trajectory in the same period, though both firms’ run-rates rely on similar forward-looking annualization methods that differ from booked GAAP revenue.[3]

Funding/Valuation Timeline and Matched Run-Rates (Post-April 2026 Updates)

• February 2026 Series G: $30B raise at $380B post-money valuation. Run-rate reported around $14B (consistent with progression to later figures). Claude Code alone exceeded $2.5B run-rate.[4]
• May 28–29, 2026 Series H: $65B raise (including $15B from prior hyperscaler commitments like Amazon) at $965B post-money valuation. Company-announced run-rate crossed $47B earlier in May (one of the last self-reported figures). This more than doubled the prior valuation amid surging enterprise demand.[1][5]
• Subsequent developments (June–October 2026): Confidential S-1 filed in June 2026 targeting potential $2T+ IPO valuation (possibly November timing). Run-rate reached >$65B by end-July (Bloomberg sources, shared in investor updates). Projections cited: $100–120B+ by end-2026 and $190–200B in 2028. Later rumors of additional ~$30B+ raises at >$900B pre-money.[6][7]

Implication for competitors: The speed of these step-ups (roughly doubling valuation while run-rate grew ~3–4x from Feb to July) signals that private AI valuations are increasingly tied to monthly momentum rather than annual results, raising the bar for new entrants needing similar hyperscaler backing or product traction to match pace.

Revenue Run-Rate Progression (Detailed Monthly/Quarterly Snapshots)

Multiple independent trackers (Bloomberg, Sacra, First Page Sage models, Reuters) align on the trajectory, with run-rate defined as annualizing the most recent month’s performance:[8][9]

• End-2025: ~$9B.
• Feb 2026: ~$14–15.3B.
• March–April 2026: ~$19–30.8B (steepest early acceleration).
• May 2026: ~$47–49.3B (Series H timing).
• June–July 2026: ~$58.9–65B+ (late July confirmed >$65B).
• August 2026 models: Up to ~$69.7B.
• Q2 2026 actual (preliminary, not run-rate): $11.5–11.6B (14x YoY from $787M in Q2 2025; exceeded full 2025 revenue of ~$4.6B). Q1 2026 actual: ~$4.2–4.73B.[10]

2025 full-year actual revenue reached ~$4.6B (12x growth from ~$386M in 2024).[9]

Note on definitions: Run-rate (or ARR in some reports) extrapolates current pace and can exceed recognized revenue due to lumpy deals or usage spikes; it is the metric Anthropic and peers emphasize in updates. Some reports flag gross vs. net recognition differences (e.g., cloud partner revenue booked gross).[11]

Implication: Entrants must demonstrate verifiable monthly scaling (not just annual guidance) to attract comparable capital; the gap between run-rate and actuals widens scrutiny on sustainability.

Revenue Breakdowns and Claude Code Role

• Overall mix (recent estimates): ~75–85% from enterprise/API/business (pay-per-token dominant); consumer/Pro/Max/Team seats smaller (~15–25% combined). Cloud partners (AWS, Google, Microsoft) contribute significantly but at lower margins due to revenue share.[3][11]
• Claude Code contribution: 15–21% of total run-rate across 2025–2026 months (e.g., 18.7–20.9% in mid-2026). Q2 2026 revenue share: ~19.4% ($2.25B of $11.6B total) at 48% gross margin. It hit $1B ARR by Nov 2025, $2.5B+ by Feb 2026, and continued tracking overall growth (not outsized). Enterprise use >50% of Claude Code revenue.[8][8]
• Other lines (Q2 2026 example): Direct API ~34% (higher margins), cloud partner API ~23% (lower margins), seats/subscriptions balance the rest.[8]

Implication: Pure consumer plays or undifferentiated API offerings face headwinds; coding/agent tools with enterprise lock-in (like Claude Code) provide a repeatable growth lever, but concentration risks persist (top customers, including coding platforms, can drive outsized shares).

Valuation Multiples, Comparisons, and Context

• Anthropic implied multiples: At May 2026 $965B valuation on $47B run-rate ≈ 20.5x. At $2T IPO target on $65B July run-rate ≈ 31x (vs. 435x on 2025 actual revenue, compressing with growth). Vs. 2028 forecasts, far lower.[12][9]
• OpenAI comparables (recent): End-2025 >$20B run-rate; Feb/Mar 2026 ~$25B; July 2026 >$40B (with >20% MoM July growth); later reports of nearing $70B annualized recurring revenue. Valuation context ~$852B post-raise. Higher consumer/ChatGPT mix (~85% in some older snapshots) vs. Anthropic’s enterprise tilt. Multiples at similar stages often 25–40x on run-rate.[13][14]
• xAI: Much smaller product ARR (~$500M mid-2026 for Grok standalone); broader AI/compute segment higher (Q2 2026 revenue examples in billions including leasing). Valuation ~$230B pre-SpaceX integration (or part of larger entity). Multiples 400x+ on low base.[15]
• Public software/AI peers: High-growth names like Palantir ~53x forward revenue; SpaceX/Cloudflare examples in 40x+ range on expected sales. Traditional SaaS 6–15x (up to 20x+ for fastest growers). AI infra commitments (Anthropic’s ~$518B over decade) add risk not always reflected in pure software multiples.[16]

Definitional/confidence flags: Figures are primarily from Bloomberg/Reuters reporting on company updates or leaked filings (high confidence on headline run-rates at funding dates); monthly breakdowns often from analyst models (medium confidence, directionally consistent across sources); breakdowns are estimates (Sacra, internal models) with no official granular public splits. Run-rate methodologies may differ slightly between firms (e.g., inclusion of certain contracts or gross/net). No single source provides exhaustive audited breakdowns.[11]

Implication for market entrants: Multiples remain elevated vs. public software but compress rapidly with scale; success hinges on matching Anthropic/OpenAI’s enterprise/API + vertical tool (coding/agent) flywheel while managing compute commitments and customer concentration. New data continues to emerge rapidly ahead of potential IPOs.
