Mean of 5 draws (0.05, 0.04, 0.04, 0.05, 0.05). (0) Not resolved: Anthropic's live pricing page (fetched 2026-09-25) still lists Claude Pro at $20/month billed monthly, and multiple trackers checked in August–September confirm no change. The Sept 14 Help Center note explicitly said "prices... are unchanged." A YES would require Anthropic to announce a national increase to the $20 monthly price before Jan 1, 2027. (a) About 3 months remain, to the Dec 31 close. (b) Status quo is NO: the price has been $20 since the 2023 launch. (c) NO scenario: Anthropic keeps using its 2026 playbook of usage pools, metering for external tools, and add-on billing for premium models (Fable), plus cheaper-to-serve models like Opus 5.5. That leaves the sticker price alone, especially during an Oct–Nov IPO roadshow when a consumer backlash would be costly. (d) YES scenario: margin pressure and a desire to show better unit economics before or after the IPO prompt a $20→$25 move. A confirmed ChatGPT Plus hike (the disputed $24 report) would give competitive cover. The Kalshi anchor is 6% and falling, and the research adds no new bullish information. The cancelled Sonnet API increase and Opus 5.5 cost cuts point the other way, so I shade slightly below the market to about 5%.

report: current state
- [2026-09-14] Anthropic's Help Center support article confirms weekly Claude Code usage limits rose permanently by 25% over pre-promotion levels for Pro, Max, Team, and seat-based Enterprise plans, but explicitly states this is a usage-limit change, not a price change: "Five-hour limits, prices, and other Claude products are unchanged." https://aicatchup.com/news/claude-code-weekly-limits-permanent-25-percent-september-2026 - [2026-09-23] An independent pricing tracker checked Anthropic's own pricing page and confirmed "the pricing has remained stable at $20/month since launch" for Claude Pro. https://aitoolsreview.co.uk/insights/claude-pricing - [2026-09-23] The same source notes Claude Pro now includes priority access to the newly launched Opus 5.5 (22 Sept 2026), but "Subscription prices are unchanged, but Pro, Max, Team and Enterprise seat plans now get higher five-hour usage limits and a bankable rate-limit reset." https://aitoolsreview.co.uk/insights/claude-pricing - [2026-09-18] A pricing guide checked directly against Anthropic's pricing page and confirmed Claude Pro at "On Anthropic's pricing page (checked 18 September 2026), Claude Code first appears at the Pro tier" , with Pro still listed at $20/month. https://coworker.ai/blog/claude-code-pricing - [2026-08-11] Anthropic cancelled a previously scheduled September 1 price increase for Sonnet 5 API tokens (from $2/$10 to $3/$15 per million tokens), making the lower introductory rate permanent instead — this was an API pricing item, not a Pro subscription price, but demonstrates Anthropic's recent posture of holding/lowering prices rather than raising them: "Anthropic has made the introductory $2 input / $10 output price the permanent standard rate, and the pricing docs now say the plainest possible thing: the previously scheduled increase to $3/$15 on September 1, 2026 will not occur." https://medium.com/@automation.labs/delete-the-sept-1-claude-price-hike-from-your-2026-budget-527d62972a3d - [2026-04-21 to 2026-04-23] Anthropic briefly removed Claude Code from the Pro plan's feature list on its pricing page, then reversed the change within 24 hours: "Anthropic reversed course in less than 24 hours. The Claude Code checkbox is back in the Pro column on claude.com/pricing, and both the landing page and documentation have been restored. Amol Avasare (Head of Growth) publicly acknowledged the communication error." This was a feature-inclusion scare, not a monthly price change. https://pasqualepillitteri.it/en/news/1211/claude-code-removed-pro-plan-anthropic-april-2026 - [2026-08-29 / 2026-09-14] Anthropic (via @ClaudeDevs and its Help Center) announced and then implemented usage-limit changes for Claude Code but at no point announced any change to the $20 monthly Pro subscription fee: "Neither source announces a change to five-hour limits, plan pricing, or Claude and Cowork limits." https://aicatchup.com/news/claude-code-weekly-limits-permanent-25-percent-september-2026 - [~2026-08 to 2026-09] Multiple independent trackers (CloudZero, IntuitionLabs, ScreenApp, SSD Nodes, Finout, UsageBox) checked Anthropic's official pricing page across August–September 2026 and consistently report Claude Pro monthly billing at $20/month, unchanged, with only the annual rate discounted to $17/month equivalent. https://www.cloudzero.com/blog/claude-pricing/, https://www.ssdnodes.com/learn/claude-pro-price-and-limits - [2026-06-15] Anthropic introduced a separate "Agent SDK" programmatic usage credit alongside subscriptions (paused on launch day per other sources), which was a usage/allocation change, not a headline monthly subscription price increase for Pro. https://levelup.gitconnected.com/anthropic-will-quietly-reprice-your-claude-pro-plan-on-june-15-the-free-20-credit-replacing-1ebd922a7786 NOT FOUND: No official Anthropic announcement, blog post, or press release proposing or confirming any increase to the headline $20/month Claude Pro price at any point in 2026 through September 25, 2026. No credible rumor or reported internal plan for a Pro monthly price hike before January 1, 2027 was found in any of the sources reviewed. BOTTOM LINE: As of September 25, 2026, Claude Pro's monthly price remains $20 (unchanged since well before the market opened), Anthropic has repeatedly emphasized "prices unchanged" language even while adjusting usage limits, and it has separately cancelled an API price increase rather than raising prices — all pointing toward "No" being the current-state-consistent outcome, absent any new announcement before December 31, 2026.
report: base rate
- [2023] Claude Pro launched at $20/month in 2023 and has never had a price increase since, according to multiple trackers: "Claude Pro has cost $20 a month since Anthropic introduced it in 2023, and the annual plan works out to $17 a month ($200 billed up front)." This 3-year stability is the key base-rate anchor. - [2026-09-25] Anthropic's own official pricing page, fetched today, still lists Pro at $20/month billed monthly or $17/month billed annually, with no indication of a scheduled increase — only standard boilerplate that "Price and plans are subject to change at Anthropic's discretion." - [2023-2026] Base rate from the closest comparable product, ChatGPT Plus: "ChatGPT Plus ($20/mo) has never increased since Feb 2023 launch—remarkably stable." Despite internal documents reportedly projecting a rise to $22 and eventually $44/month, "this predicted price increase did not happen... ChatGPT Plus has remained at $20/month throughout 2026 — the $22/month figure below was a 2024 leaked-document projection for late 2025 that never materialized." This is the single closest reference-class event (leading flat-rate AI chat subscription) and it resolved "No" over roughly 3.5 years, suggesting flat consumer AI subscription prices are unusually sticky even amid heavy compute-cost pressure. - [2026-04-21/22] Anthropic did test cutting Claude Code out of the Pro tier (not a price increase, a feature restriction) for one day before reversing: "Anthropic's pricing table on April 21, 2026: Claude Code unavailable on the Free and Pro plans, accessible only from Max 5x and above... The next day, the configuration was restored." This shows Anthropic's revealed preference is to solve rising compute costs via usage/feature restructuring rather than a headline price hike on Pro. - [2026-05-14/06-15] Anthropic separated "programmatic" (Agent SDK/API-key) usage into its own credit pool rather than raising the $20 price: "Starting June 15, 2026, paid Claude subscriptions split into two pools... The June 15 split restructures subscription plans only." Commentary characterized it explicitly as "not a generic price hike. It's a surgical re-pricing of one specific kind of usage." This is a second historical instance of Anthropic choosing structural/usage-based changes over a sticker-price increase. - [2026-04-08] Separately, Anthropic ended flat-rate treatment for third-party "OpenClaw"-style external tools riding on Claude subscriptions, again a usage/access restructuring rather than a Pro sticker-price change: "Anthropic ends Claude Pro's flat pricing. External tools pay per use. Flat subscriptions can't survive the agent era of heavy compute." Even this "ends flat pricing" framing only affected external tool access, not the published $20 Pro monthly figure. - [2026-08-10/11] On the API side (not Pro subscription), Anthropic actually cancelled a scheduled price increase rather than implementing one: "Anthropic had originally framed this as launch pricing through August 31, 2026, with a step-up to $3/$15 scheduled for September 1. On August 10, 2026, Anthropic cancelled that increase and made $2/$10 the standard, ongoing rate." This shows a recent, concrete instance where a scheduled Anthropic price rise was walked back under competitive/community pressure — directionally bearish for a Pro price hike this year. - [2026-09-16] The most recent notable Pro-plan change is a feature merge (Cowork into main Claude app), not pricing: "On 16 September 2026 Anthropic announced that Cowork and chat are merging into one Claude, rolling out to Pro and Max first, with Team and Free to follow." - [2026 industry outside-view] One pricing-analysis piece frames the broader AI subscription market as still in a stable phase after an initial land-grab: "Most major AI tools went from free to $20–30/month for basic paid access, up to $200/month for premium tiers — a shift that happened largely between 2023 and 2025." Note this same source speculates rising infrastructure spend makes "further price increases across the category... more likely than not," but this is analyst opinion, not evidence of an announced Anthropic action. - [2026-08] Multiple independent, recently-updated pricing trackers (CloudZero, IntuitionLabs, SSD Nodes, eesel, subbuddy) all convergently confirm the unchanged $20/$17 Pro price through August-September 2026, giving high confidence there has been no national price increase to date this year. BOTTOM LINE: The reference class (Claude Pro's own 3-year unbroken $20 history, and the closest comparable product ChatGPT Plus's 3.5-year unbroken $20 history despite leaked plans to raise it) shows flat-rate consumer AI chat subscriptions are historically very sticky, and Anthropic's own 2026 track record shows a repeated pattern of solving rising compute costs via usage-pool restructuring or even cancelling scheduled increases (the Sonnet API price rise) rather than raising the headline Pro subscription price — all of which argues for a low base-rate likelihood of a Pro monthly price increase being announced before January 1, 2027. NOT FOUND: No evidence of any announced or rumored Claude Pro monthly *price* increase (as opposed to feature/quota restructuring) specifically for the remainder of 2026; no Kalshi-specific market odds, polls, or other prediction-market/forecaster estimates for this exact question were found in search results.
report: yes case
**Strongest path to YES: margin pressure + IPO timeline forces a "surgical" repricing that also touches the Pro sticker price, following Anthropic's own 2026 playbook and OpenAI's precedent of raising its direct competitor's headline consumer price.** - [2026-04-15] Anthropic already raised effective prices for a subscription tier once in 2026: The Information reported Anthropic shifted Claude Enterprise subscriptions away from a flat fee of up to $200 per user per month to a usage-based model charging for compute on top of a $20 monthly seat fee , which one compliance-negotiation expert said could potentially triple costs for some enterprise customers . This shows Anthropic has a demonstrated 2026 precedent of increasing what customers actually pay on a named subscription tier once margins are threatened — the same mechanism could be pointed at Pro. - [2026-04-21/23] Anthropic separately tested pulling Claude Code out of the $20 Pro tier entirely for about a day before reversing under backlash; one analysis argued the reversal was tactical, not strategic, concluding the decisive factor is the ratio between margin per Pro user and the actual cost of Opus inference… if demand continues to grow faster than capacity, the price hike becomes math rather than choice . This is a live, named mechanism (compute-cost/margin math) that colleagues' reports treat as resolved but which the sourced analysis frames as only deferred, not abandoned. - [2026-06-26/07-27] CEO Dario Amodei has publicly and repeatedly flagged existential-scale compute economics this year, warning "Even a one-year slowdown in 10x growth could make trillion-dollar infrastructure bets unsustainable," and separately that Anthropic must generate hundreds of billions in annual revenue to sustain rising infrastructure costs or risk existential financial pressure , with industry-wide inference spend potentially push[ing] total industry spending close to $1 trillion by late 2027 . Separately he told Dwarkesh that mistimed compute purchases could be "ruinous" for the company . This is a plausible, dated, named-executive motive for a 2026 price action, distinct from the "prices unchanged" boilerplate already covered. - [2026-04-08] Anthropic's own April repricing memo already showed willingness to break "unlimited" flat-rate promises when costs outrun revenue: Anthropic made its biggest pricing shift since launching Claude Pro… Claude Pro and Max subscribers can no longer use their flat-rate monthly plans to power third-party agent frameworks like OpenClaw , forcing some users into per-use billing. Commentary on this event explicitly framed it as evidence that as these systems become more capable, they also become more expensive to serve… the strategic direction is hard to miss: advanced coding workflows are becoming expensive enough that providers may no longer want to bundle them cheaply for everyone . - [2026-09-25 est.] Anthropic is reportedly targeting an IPO within 2026 per Wikipedia's sourced summary: the company is privately held but reportedly plans an initial public offering in 2026… valued at US$965 billion in a May 2026 Series H funding round . A pre-IPO company facing a documented negative-margin history has clear incentive to demonstrate improving unit economics on its flagship consumer product before or shortly after listing, which raises the plausibility of a Q4 2026 pricing action timed to a roadshow/IPO narrative. - [2026-04-27] Independent financial reporting citing The Information shows the underlying cost pressure is real and recent, not hypothetical: Anthropic posted a negative 94% gross margin in 2024… for every dollar of revenue, it spent nearly $2 on compute costs… Anthropic expects to burn approximately $3 billion in cash in 2025 and projects it won't stop burning cash until at least 2027, with real profitability unlikely before 2028 . This margin math is the concrete financial mechanism that could force a Pro price increase before Anthropic's IPO window closes. - [2026-08-22, disputed] One pricing tracker (Free AI News) reports that OpenAI's direct competitor ChatGPT Plus already broke the $20 industry floor mid-2026: it states ChatGPT Plus became the entry-level paid option at $24 per month after June 15, 2026… a $4 increase from the prior $20 price . If accurate, this removes the "no comparable has moved" argument underpinning the NO case and establishes a direct, recent industry precedent for raising a $20 flat-rate AI chat subscription. Caveat: this claim is contradicted by several other trackers checked in September 2026 (CloudZero, tldv, aipricing.guru) that still list ChatGPT Plus at $20/month, so it should be treated as an unconfirmed/possibly erroneous report rather than a settled fact — but its mere circulation shows analysts consider a mid-tier AI-chat price hike newsworthy and plausible in exactly this timeframe, which is the type of environment in which a Claude Pro increase could occur without drawing disproportionate surprise. - [2026-07] Anthropic's Team plan, a closely adjacent consumer/prosumer tier, already carries a higher headline monthly number than Pro ( Team Standard seats are $20/seat/mo annual or $25 monthly ), showing Anthropic is comfortable with a $25 monthly price point in its own product line — a smaller psychological jump would be needed to move Pro from $20 to $25 than to invent a new price band. BOTTOM LINE: There is no confirmed announcement of a Claude Pro price increase, but the strongest evidence-based YES path is a margin-driven, IPO-timed repricing: Anthropic has already used usage-based and feature-carve-out repricing three separate times in 2026 (Enterprise in January/April, OpenClaw/agent access in April, Agent SDK credits in June) whenever compute costs outran a specific revenue stream, its CEO has repeatedly and publicly flagged existential-scale compute economics through Q3 2026, and Anthropic is reportedly pursuing an IPO within the same 2026 window that a Pro price increase would need to land before to satisfy the "before Jan 1, 2027" resolution criterion. NOT FOUND: No official Anthropic statement proposing, previewing, or confirming a Claude Pro monthly price change; no leaked internal Anthropic roadmap analogous to OpenAI's 2024 leaked $22/$44 ChatGPT Plus documents; and the reported June 2026 ChatGPT Plus $20→$24 increase could not be corroborated on OpenAI's own pricing page via the sources reviewed, so it remains an unconfirmed, contested claim rather than verified fact.
report: no case
- [2026-09-25] The current official Anthropic pricing page (fetched today) lists Pro at $20/mo, with annual billing dropping to $17/month , and the only "Latest news" banner concerns the Cowork-to-Claude merge, not any pricing change — confirming zero pricing announcement is queued on Anthropic's own live page. https://claude.com/pricing - [2026-09-23] Anthropic's newest model launch (Opus 5.5, Sept 22) was expressly framed as a cost-reduction move: Anthropic said the new model "performs at the level of its flagship Fable 5.1 model but costs around 40% less to run than Opus 5" , and this cheaper-to-serve model was rolled directly into Pro's existing $20 price rather than used to justify an increase — the opposite mechanism of a price hike. https://fortune.com/2026/09/23/pace-the-profits-ai-companies-seemed-to-say/ - [2026-09-23] The same Fortune piece frames both Anthropic and OpenAI's September moves as pacing down costs for "increasingly cost-conscious businesses" amid "growing competition from lower-cost open weight models" — a competitive dynamic that argues against a unilateral consumer sticker-price increase, since it would cede ground to cheaper alternatives right as rivals cut prices too. https://fortune.com/2026/09/23/pace-the-profits-ai-companies-seemed-to-say/ - [2026-05-28] Anthropic closed a $65 billion Series H at a $965 billion post-money valuation — "marking what could be the AI startup's last private fundraising before debuting on the public markets" — giving the company an enormous cash cushion that removes near-term financial pressure to raise the flagship consumer subscription price before year-end. https://techcrunch.com/2026/05/28/anthropic-raises-65-billion-nears-1t-valuation-ahead-of-ipo/ - [2026-08-17] Bloomberg-sourced reporting shows Anthropic's annualized revenue run rate has already surpassed $65 billion, up more than 7x from end-of-2025 levels, with some projections putting full-year 2026 revenue at $100–120 billion — this revenue trajectory is being driven by usage growth and enterprise/API expansion, not by a Pro subscription price increase, further reducing the incentive to touch the $20 sticker price. https://www.startuphub.ai/ai-news/ipo-watch/2026/anthropic-ipo-roadshow-investor-meetings-2026-07-21 - [2026-06-01] Anthropic confidentially filed a draft Form S-1, and as of Sept 21 reports the IPO window may be slipping from October toward November 2026 "according to reports published on September 21," with the shift intended "to incorporate third-quarter financial results into its public-market preparation" — during an active pre-IPO quiet/roadshow period, an unforced, headline-grabbing price increase on a consumer flagship product is a classic reputational risk companies avoid, favoring "no” through year end. https://www.neoteo.com/en/anthropic-may-push-its-ipo-to-november-after-confidential-s-1-filing - [2026-05/06] When Anthropic wanted to monetize a genuinely more expensive new model (Fable 5), it did so by excluding it from the flat subscription pools and instead charging "starting on June 23, access to the model will no longer be included in paid subscriptions, including the company's $200-per-month plan... instead be subject to usage-based billing on top of the monthly subscription, with charges calculated according to the number of tokens consumed" — a repeated, now well-established revealed preference for solving unit-economics problems via add-on/usage billing rather than the headline monthly fee. https://cafetechinenglish.substack.com/p/anthropic-shakes-up-its-pricing-strategy - [2026-05-04] Even amid heavy compute pressure — "Anthropic plans to spend approximately $19 billion on training and inference compute in 2026, roughly matching its full-year revenue. Gross margins reportedly compressed to around 40% after inference costs ran 23% over projections" — the company's public response was fundraising and cheaper-model releases, not a Pro price increase, indicating cost pressure alone has not yet translated into consumer pricing action even when the case for it (compressed margins) was strongest earlier in the year. https://www.forbes.com/sites/jonmarkman/2026/05/04/anthropics-900b-funding-round-set-to-surpass-openai/ - [2026-04-08] Anthropic's most aggressive 2026 "pricing" move to date was to end flat-rate treatment only for third-party agent frameworks (OpenClaw-style tools) hitting Pro/Max via "Starting April 4, 2026, Claude Pro and Max subscribers can no longer use their flat-rate monthly plans to power third-party agent frameworks... Users who want to keep running autonomous agents through external tools now have to pay per use" — again leaving the base $20 subscription untouched, showing three separate 2026 precedents (Fable exclusion, SDK credit split, OpenClaw restriction) of restructuring around the price rather than raising it. https://dapta.ai/blog-posts/ai-news-week-14-anthropic-claude-pricing/ - [2026-04-09/2025] Anthropic's own product lead, discussing the original Max launch, said the company is "not ruling out launching even pricier subscriptions someday" and would "always keep a number of exploratory options available" — but this remains a vague, open-ended statement about possible new higher tiers (e.g., a hypothetical $500/mo plan), not any commitment to raising the existing $20 Pro price, and no such new tier has materialized in the 2026 data reviewed. https://techcrunch.com/?p=2991134 BOTTOM LINE: Every mechanism Anthropic has used in 2026 to address rising compute costs or monetize better models — SDK credit splits, external-tool metering, Fable usage-based add-ons, and cheaper-to-serve model swaps (Opus 5.5) — has left the $20 Pro sticker price untouched, and the company's imminent IPO/roadshow window (Oct–Nov 2026) creates strong incentive to avoid an unforced, headline consumer price hike during a highly scrutinized pre-listing period, all reinforcing the case for continued NO through year-end. NOT FOUND: No S-1/prospectus language (still confidential) addressing subscription pricing strategy; no analyst or leaked-document report specifically projecting a Claude Pro price increase timed to the IPO; no statement from Amodei or other named Anthropic executives (as opposed to product-lead comments from 2025) directly ruling in or out a 2026 Pro price change.

(0) Not resolved: Anthropic's live pricing page (fetched 2026-09-25) still lists Claude Pro at $20/month billed monthly, and multiple trackers checked in August–September confirm no change. The Sept 14 Help Center note explicitly said "prices... are unchanged." A YES would require Anthropic to announce a national increase to the $20 monthly price before Jan 1, 2027. (a) About 3 months remain, to the Dec 31 close. (b) Status quo is NO: the price has been $20 since the 2023 launch. (c) NO scenario: Anthropic keeps using its 2026 playbook of usage pools, metering for external tools, and add-on billing for premium models (Fable), plus cheaper-to-serve models like Opus 5.5. That leaves the sticker price alone, especially during an Oct–Nov IPO roadshow when a consumer backlash would be costly. (d) YES scenario: margin pressure and a desire to show better unit economics before or after the IPO prompt a $20→$25 move. A confirmed ChatGPT Plus hike (the disputed $24 report) would give competitive cover. The Kalshi anchor is 6% and falling, and the research adds no new bullish information. The cancelled Sonnet API increase and Opus 5.5 cost cuts point the other way, so I shade slightly below the market to about 5%.

(0) The condition has not been met. Anthropic's live pricing page (fetched 2026-09-25) still shows Pro at $20/month billed monthly and $17/month billed annually, with no announced increase, and multiple trackers from August and September agree. (a) About three months remain until the Dec 31, 2026 deadline. (b) If nothing changes, Pro stays at $20, where it has been since its 2023 launch, and the market resolves No. (c) The likely NO path: Anthropic keeps handling compute costs through usage-pool splits, usage-based add-ons (Fable, Agent SDK, OpenClaw), and cheaper-to-serve models like Opus 5.5, rather than raising the sticker price. It avoids a headline consumer price hike during its Oct–Nov IPO roadshow, especially with rivals pressuring prices down (OpenAI reportedly weighing cuts, and Anthropic cancelling the scheduled Sonnet API increase). (d) The YES path: margin pressure plus the IPO narrative push Anthropic to announce a Pro increase (e.g., $20→$25) in Q4. This could follow the unconfirmed report that ChatGPT Plus rose to $24, or be bundled with new models. The Kalshi anchor is 6% and has been falling (-12% over 30 days), consistent with no news. Given the strong revealed preference for restructuring around the price and the IPO timing, I shade slightly below the market to about 4%.

(0) Not resolved. The live claude.com/pricing page (fetched today) still shows Pro at $20/month billed monthly. Multiple trackers checked through Sept 18–23 confirm no change, and the Sept 14 Help Center note explicitly says "prices ... are unchanged." A YES would require Anthropic to announce a national Pro monthly price increase before Jan 1, 2027. (a) About 3 months remain (Sept 25 to Dec 31, 2026). (b) Status quo is No: Pro has been $20 since its 2023 launch, and the closest comparable, ChatGPT Plus, has also held at $20 despite leaked plans to raise it. (c) NO scenario: Anthropic keeps handling cost pressure through usage pools, add-on billing (Fable, Agent SDK, OpenClaw metering) and cheaper models like Opus 5.5. It avoids a headline consumer price hike during its Oct–Nov IPO roadshow, backed by a $65B raise and a $65B+ revenue run rate. (d) YES scenario: margin pressure plus the IPO narrative push a Q4 repricing, such as $20→$25 to match Team monthly seats. This could be announced alongside a new model or plan restructure, perhaps after the IPO lists in November. The Kalshi anchor is 6% and has been falling (-12% over 30 days). The research surfaced no rumor or leak, and the recent API price-hike cancellation reinforces Anthropic's preference for holding sticker prices. I shade slightly below the market to about 4%, keeping some weight on a post-IPO surprise.

(0) The condition has not already been met: Anthropic's live pricing page still lists Claude Pro at $20 per month and shows no announced increase, corroborated by several September pricing checks. (a) About 97 days remain until the December 31, 2026 close, during which Anthropic would need to announce any national monthly-price increase greater than 0% for Yes. (b) If nothing changes, the unchanged $20 price makes No the resolving outcome. (c) No results if Anthropic continues addressing compute costs through usage limits, add-on billing, feature restructuring, and cheaper models rather than changing Pro's sticker price, as it repeatedly has in 2026. (d) Yes could result from a Q4 margin- or IPO-driven repricing, plausibly moving Pro toward the $25 price point already used for monthly Team seats. I anchor on Kalshi's 6% Yes price and move slightly lower because the latest model launch reduced serving costs while retaining the $20 price, no credible rumor or roadmap for an increase was found, and both Claude Pro and ChatGPT Plus have long histories of price stability. The remaining 5% reflects substantial compute-cost pressure, Anthropic's willingness to reprice adjacent offerings, and the possibility of an unexpected year-end announcement.

(0) The condition has not already been met: Anthropic’s live pricing page still lists Claude Pro at $20 per month and shows no announced 2026 increase, while multiple September checks corroborate that price. (a) Roughly 97 days remain until the December 31, 2026 close, so Anthropic would still need to announce any national monthly-price increase before then for Yes. (b) If nothing changes, the unchanged $20 price makes No the resolution. (c) No results if Anthropic continues addressing compute costs through usage limits, metered add-ons, feature restructuring, and cheaper models, as it repeatedly has during 2026. (d) Yes could result from a Q4 margin- or IPO-driven repricing, but there is no official proposal, credible leak, or corroborated rumor supporting that path. I anchor on Kalshi’s 6% Yes price and move slightly lower to 5% because the latest Opus 5.5 rollout increased value at the existing price, Anthropic recently cancelled an API increase, and both Claude Pro and its closest comparator have multi-year histories of holding at $20.
