1. Interpreting the question and outcomes

The event asks which valuation threshold Anthropic is most likely to reach (or exceed) at least once by December 31, 2026, as measured by Nasdaq Private Market (NPM) or, if it IPOs, by public-market capitalization under a clearly specified methodology. There are 13 ordered thresholds (e.g., $600B, $700B, $800B, $1.0T, $1.25T, $1.5T, up to $5.0T). You want my single most likely final outcome and its probability, based purely on fundamentals and public information, not on prediction market prices.

2. Current valuation and NPM data

Private round valuations and NPM pricing

• In May 2026, Anthropic announced a $65B Series H funding round at a $965B post-money valuation, led by major growth investors [1][2]. This anchors a floor: the company has already been priced just below the trillion-dollar mark in a large, arm’s-length equity financing.

• Nasdaq Private Market (NPM) lists an Anthropic price per share of $688.81 as of July 13, 2026, labeled explicitly as the NPM price based on secondary transactions [3]. While the page does not state a total valuation, this price is consistent with secondary reporting that Anthropic is changing hands at implied valuations in roughly the $1.2–1.4T range by July 2026 [4].

• Separate coverage notes Anthropic has “soared to a $1.2 trillion valuation on secondary markets” [4]. Combined with the earlier $965B primary valuation, this strongly suggests that by mid-2026 the company is already trading around or above the $1.25T threshold in some private or quasi-private venues.

Given the resolution criteria, NPM is the primary arbiter pre-IPO. Even if some secondary markets are richer than NPM, the NPM price itself is tracking similar levels, which makes crossing $1.25T via its methodology very likely.

3. Revenue scale and growth trajectory

Anthropic’s valuation is underpinned by extraordinary revenue growth:

• Multiple analyses and company disclosures indicate Anthropic went from about $1B annualized revenue in late 2024 to roughly $4B by mid-2025, $9B by year-end 2025, and $14B in early 2026 [5][6].

• By May 2026, Anthropic reported a run-rate revenue of about $47B at the time of the Series H close [1][7].

• Subsequent commentary and data points suggest the ARR has continued to climb, with reports around July 2026 placing ARR near $69B [8].

So within ~18 months, Anthropic has plausibly gone from $1B to $69B in run-rate revenue. The exact monthly step pattern is noisy, but the broad picture is clear: it is one of the fastest-growing large companies ever observed.

4. Valuation multiples consistent with current and future pricing

Valuation must be considered relative to revenue and margins:

• Sector studies on AI-focused companies in 2026 show private AI leaders often trading at 20–30x revenue multiples, with higher outliers for category-defining firms [9][10].

• If Anthropic’s ARR is about $69B by mid-2026 and grows further into late 2026, even conservative multiples yield very high valuations:

  • If ARR in December 2026 is in a conservative range of $100–135B (consistent with growth slowing from recent pace but still strong), applying a 20–30x multiple implies valuations between roughly $2.0T and $4.0T (e.g., $102B × 20x = $2.0T; $135B × 20x = $2.7T; $135B × 25x = $3.4T) based on simple modeling.

  • Even if one assumes the market compresses multiples sharply for macro or sentiment reasons—say down to 12–15x—this still supports valuations of $1.2–2.0T at the projected revenue scale.

• At the time of the $965B Series H, reports noted the company was valued at roughly 20x its then-reported run-rate revenue [2], which fits well within the AI multiple ranges and suggests the market would not view $1.25T as a stretch if revenue continues to climb.

Overall, on fundamentals alone, valuations at or above $1.25T are easily justified both by comparable multiples and by Anthropic’s growth and improving margin profile.

5. Profitability and margin structure

Profit and margins matter for sustaining high multiples:

• Analyses of Anthropic’s financials in 2026 indicate gross margins moved from the high-30% range toward the mid-40s and possibly higher as compute contracts and software mix shifted [11][12]. Some commentary suggests margins could ultimately reach 70%+ as infrastructure scales and efficiency improves [11].

• The company is projected (and in some reports, already on track) to post its first operating profit in Q2 2026, with an expected operating profit of roughly $0.5–0.6B on quarterly revenue around $10.9B [13].

The combination of high growth, rising margins, and a near-term turn to profitability makes it far more likely that investors will sustain or expand current multiples rather than aggressively compress them in the near term, absent a systemic AI or macro shock.

6. IPO timing and its effect on the valuation path

The resolution criteria explicitly incorporate post-IPO market capitalization if Anthropic lists before year-end 2026.

Current information on IPO plans:

• Anthropic confidentially filed for an IPO on June 1, 2026 [14][15].

• Multiple sources indicate it is targeting an IPO as early as October 2026, with a reference valuation around the Series H level of $965B and a plausible listing range “near-
  trillion” or “near-
  $1T” that could be exceeded on the first day [14][15][16].

• Some forecasts and coverage argue that a first-day market cap around or above $1.0–1.1T is a base case, with upside depending on market conditions [16].

From a valuation dynamics perspective:

• Large, highly anticipated tech IPOs commonly price at a modest discount to the intrinsic or secondary valuation to ensure a successful bookbuild, then trade up 10–30% (or more) on debut. If Anthropic prices at or slightly under the $965B last private valuation, a standard first-day premium alone could put market cap over $1.1–1.3T.

• Because the resolution rule uses the maximum market capitalization on any trading day through December 31, even a temporary spike during volatile initial trading could be enough to register a valuation above $1.25T.

• If the IPO slips to late December or is pulled entirely, NPM pricing remains the fallback. Given NPM already reflects share prices consistent with $1.2–1.4T equivalents in mid-2026, simply holding current levels or modestly rising would likely cause NPM to cross $1.25T at least once.

Thus, whether via IPO or continued private/NPM trading, there are multiple independent mechanisms by which Anthropic can hit $1.25T.

7. Assessing higher thresholds ($1.5T, $2.0T, etc.)

To choose the single most likely outcome, we must consider not just whether $1.25T is hit, but how likely it is relative to the higher thresholds in the same ladder.

Given the revenue and multiple analysis:

• $1.5T: With mid-2026 secondary pricing already in the $1.2–1.4T range, and with continued revenue growth plus an IPO premium, a peak valuation between $1.4–1.8T by year-end is very plausible. I would place the probability of Anthropic hitting $1.5T at least once by December 31 in the ballpark of ~70–75% on fundamentals.

• $1.75T: Requires somewhat stronger revenue and/or stronger risk sentiment, but still well within reach if ARR does land above $100B and the market ascribes a 20x+ multiple. I would estimate something like 55–60% probability on fundamentals.

• $2.0T: This level assumes continued hyper-growth, relatively benign macro conditions, and sustained belief in AI-driven profitability. The modeling with $100–135B ARR and 20x+ multiples supports this as a central/base scenario, but with material downside risk if growth slows or multiples compress. I’d assign around ~45% probability to hitting $2.0T at least once.

• $2.5T and above: These require a combination of (a) near-flawless execution, (b) very strong risk-on markets, and (c) investors granting top-decile multiples. Plausible, but clearly less likely than the above thresholds.

In an ordered-threshold structure, the probability that a given threshold is hit at least once decreases as the threshold increases. On my independent estimates, the probability ordering is:

• P(hit $1.25T) > P(hit $1.5T) > P(hit $1.75T) > P(hit $2.0T) > ...

With rough numbers like:

• P($1.25T) ≈ 85–90%

• P($1.5T) ≈ 70–75%

• P($1.75T) ≈ 55–60%

• P($2.0T) ≈ 40–50%

Given these, $1.25T is clearly the most likely individual outcome among the thresholds.

8. Key downside risks

The main scenarios in which Anthropic might not hit $1.25T:

1. Severe AI sector repricing: A large correction in AI valuations (e.g., due to overcapacity, regulation, or a funding crunch) that cuts revenue multiples sharply and drives NPM and secondary valuations back below $1.0T, without recovery before year-end.

2. Company-specific shock: Major product failures, security incidents, or governance crises that significantly harm Anthropic’s perceived prospects relative to peers.

3. IPO cancellation plus price decline: An IPO delay or cancellation combined with softening demand on NPM such that the company never sees a day with NPM- or market-cap-implied valuation at or above $1.25T during the specified period.

While these are real possibilities and collectively worth nontrivial probability mass (hence not assigning >95% confidence), they are counter to the current combination of revenue trajectory, margin improvement, and investor demand for frontier AI exposure.

9. Synthesis and final forecast

Pulling everything together:

• Anthropic is already valued at $965B in a large, recent primary round and is trading around $1.2–1.4T in secondary markets by mid-2026.

• Revenue growth is extraordinary, with ARR plausibly in the $69B+ range as of July 2026 and a realistic path to $100B+ ARR by year-end.

• AI leaders in 2026 justify 20–30x revenue multiples; even at the low end of plausible future multiples, this supports valuations at or above $1.25T.

• An IPO is likely in Q4 2026, and standard first-day trading behavior plus the resolution rule (using daily max market cap) make a transient spike above $1.25T highly probable.

• Among the set of thresholds, $1.25T is the lowest one that is clearly in the “almost certain” category based on fundamentals, making it the single most likely outcome.

On this basis, I forecast that the most likely resolution is that Anthropic’s valuation does hit the $1.25T level at least once by December 31, 2026, with an estimated probability of about 85%.

10. Final structured answer

• Single most likely outcome: Anthropic’s valuation hits $1.25T by December 31, 2026.

• Estimated probability for this specific outcome: ~85%.

This is my best-effort, evidence-based independent forecast given the information available as of mid-2026.
