final rationale
Mean of 2 draws (0.04, 0.04) after one crux research pass. (0) Nothing has resolved yet, and No is in effect locked in by the calendar. Thaler v. Perlmutter (25-449), the only AI-copyright petition to reach the Court, was denied on Mar 2, 2026, per the docket. The orders page through Oct 8, 2026 shows no AI-copyright grant. (a) About 11 weeks remain until Jan 1, 2027. (b) If nothing changes, no grant occurs and the market resolves No. (c) No path: ROSS uses its reported unopposed extension to Nov 3 to petition the Third Circuit for rehearing en banc, which delays the cert clock. Even a petition filed in November would face a 30-day response period, a likely call for the Solicitor General's views, and an interlocutory, non-generative-AI posture with no circuit split. Any decision would then come in 2027 or later; Thaler took about 5 months from filing to denial. (d) Yes path: ROSS skips rehearing and files in late October. Thomson Reuters waives its response and the Court grants at a December conference. Each step is unusual, and together they are very unlikely. A small extra chance comes from some unseen tangential AI-copyright petition being granted. The Kalshi price is 15% (bid 11 / ask 19, thin volume) and Polymarket is 12.5%. That pricing seems to reflect ROSS's announced intent to seek review rather than the procedural calendar. The rehearing-extension evidence and the timing arithmetic justify going well below the market.

The price anchor is kalshi_direct. The resolution source is the Supreme Court docket and its orders lists. court_docket can show whether there are pending cert petitions in AI copyright cases such as Thaler v. Perlmutter (the AI authorship case), which is the key structured signal. Related markets on Kalshi and Polymarket give cross-venue checks, and one targeted article search covers cert petition status and conference dates.

Research loops, bottom lines
- current state: As of 2026-10-12 I found no AI-copyright case pending at the Supreme Court. The one petition, Thaler, was denied on 2026-03-02. The only appellate AI fair-use ruling (Third Circuit, ROSS, 2026-09-29) is too fresh to reach a cert grant before Jan 1, 2027 on a normal schedule. Generative-AI cases are still at the district or circuit stage.
- base rate: Historically, the only AI-copyright petition to reach the Court (Thaler) was denied after about 5 months, and the one live candidate (ROSS) is only about two weeks past an interlocutory Third Circuit ruling. The procedural calendar makes a grant before 2027 very unlikely, and the base rate for cert grants is low. Generative-AI cases are still in district court.
- yes case: The only credible YES path is ROSS filing a fast cert petition and the Court granting at a December conference. That is a compressed schedule, and ROSS's interlocutory posture and non-generative AI make it a contested vehicle. I found nothing showing it has begun.
- no case: For a Yes, ROSS would need to file within weeks, the SG would need to waive or skip a CVSG, and the Court would need to grant before year-end. It would also have to do this on an interlocutory, non-generative, no-split record, and no such petition has been reported filed. The status quo is no grant, and the only live candidate cannot move fast enough under the Court's ordinary process.
Crux follow-up
- The evidence favours No, and strongly. The earliest plausible grant is well after the Jan 1, 2027 close, and the only AI-copyright case the Court has handled, Thaler, was denied. The residual risk is an unseen petition or an unusually fast ROSS filing and grant.

report: current state
- [2026-03-02] The Supreme Court denied certiorari in Thaler v. Perlmutter (No. 25-449). The petition asked whether AI-only works can be copyrighted. This was the only AI-copyright cert petition I found, and it was denied rather than granted. https://ipwatchdog.com/2026/03/02/supreme-court-denies-thalers-latest-attempt-register-copyright-ai-generated-image/
- [2026-01-23] The DOJ/Solicitor General opposed cert in Thaler. It called the case a poor vehicle because Thaler disclaimed any human contribution. The Court followed that position. https://ipwatchdog.com/2026/01/28/doj-urges-supreme-court-deny-cert-thalers-latest-bid-copyright-work-created-ai/
- [2026-03-16] Commentary after the denial says the human-authorship rule stands. The question of how much human input is enough for AI-assisted works remains open and unaddressed by the Court. https://www.mayerbrown.com/en/insights/publications/2026/03/supreme-court-denies-review-in-ai-authorship-case
- [2026-09-29] The Third Circuit decided Thomson Reuters v. ROSS Intelligence. It affirmed that ROSS's use of Westlaw headnotes to train a non-generative AI tool was not fair use. It was the first federal appellate ruling on AI-training fair use. Ballard Spahr (2026-10-02) says it does not decide generative-AI training. https://www.ballardspahr.com/insights/alerts-and-articles/2026/10/third-circuit-addresses-fair-use-in-ai-training-but-leaves-generative-ai-questions-unresolved
- [2026-10-01] Tech Times says the Third Circuit ruling is non-binding on the Ninth Circuit, where the Bartz v. Anthropic and Kadrey v. Meta cases arose. https://www.techtimes.com/articles/328380/20261001/ai-training-fair-use-loses-first-appellate-test-generative-ai-gets-explicit-carve-out.htm
- [2026-10-12] Timing for ROSS: the decision is about two weeks old. A rehearing petition is due within 14 days of judgment, and a cert petition within 90 days (or after a rehearing denial). So a cert petition could not realistically be filed, briefed, conferenced and granted before Jan 1, 2027 unless the Court expedites. I found no report of any such filing.
- [2025-06-23] The Bartz v. Anthropic and Kadrey v. Meta rulings were district-court rulings from N.D. Cal. They are not at the Supreme Court. https://www.congress.gov/crs-product/LSB10922
- [2026] The Berkeley BCLT 2025–26 year-in-review lists Thaler (cert denied March 2026) as the Supreme Court's AI-copyright action. It does not list any pending cert-stage AI-copyright case. https://www.law.berkeley.edu/research/bclt/bclt-legal-analysis/internet-computer-law-s1/
BOTTOM LINE: As of 2026-10-12 I found no AI-copyright case pending at the Supreme Court. The one petition, Thaler, was denied on 2026-03-02. The only appellate AI fair-use ruling (Third Circuit, ROSS, 2026-09-29) is too fresh to reach a cert grant before Jan 1, 2027 on a normal schedule. Generative-AI cases are still at the district or circuit stage.
NOT FOUND: Any pending AI-copyright cert petition. Any rehearing or cert filing in Thomson Reuters v. ROSS. Any scheduled Supreme Court conference on an AI-copyright case before 2027. The search tool hit a call limit, so the ROSS follow-up search did not run. The Supreme Court docket pages were not checked directly.
report: base rate
- [2026-03-02] The Supreme Court denied cert in Thaler v. Perlmutter (No. 25-449), the only AI-copyright petition I found that reached the Court. Timeline from the docket: petition filed 2025-10-09, response requested 2025-11-26, government opposition filed 2026-01-23, reply 2026-02-09, denied 2026-03-02. That is about 4.8 months from filing to denial, even for a case denied without a grant. The Solicitor General opposed review. https://www.scotusblog.com/cases/case-files/thaler-v-perlmutter
- [2026-01-28] The DOJ argued that Thaler was a narrow, poor vehicle because Thaler disclaimed any human creative contribution. The Court followed that advice. https://ipwatchdog.com/2026/01/28/doj-urges-supreme-court-deny-cert-thalers-latest-bid-copyright-work-created-ai/
- [2026-09-29] The Third Circuit affirmed Thomson Reuters v. ROSS (No. 25-2153). This was the first federal appellate ruling on fair use in AI training. The court held that ROSS's use was not fair use. It came on interlocutory appeal, and the district court has not yet resolved damages or some remaining claims. https://www.jw.com/news/insights-ai-copyright-fair-use-case/ and https://patentlyo.com/patent/2026/10/ease-is-not-necessity-third-circuit-affirms-no-fair-use-in-thomson-reuters-v-ross.html
- [2026-09-29] The Third Circuit's judgment notice gives 14 days to petition for rehearing, or 45 days if the US is a party. It refers parties to the Supreme Court rules on cert timing. https://chatgptiseatingtheworld.com/wp-content/uploads/2026/09/Thomson-Reuters-Enterprise-Centre-GmbH-et-al-v.-Ross-Intelligence-Inc-Entry-BL-207.pdf
- [2026-10-04] Reports say ROSS has said it will seek Supreme Court review. The commentator Aaron Moss doubts this is a good vehicle: it was interlocutory, damages are unresolved, ROSS is defunct, and its AI was not generative. He says cleaner generative-AI cases are coming up in the lower courts. I did not find a filed rehearing petition or cert petition. https://copyrightlately.com/thomson-reuters-v-ross-fair-use-generative-ai/
- [2026-10-04] Generative-AI cases are still at the district-court stage. Summary-judgment argument in Concord v. Anthropic is set for Oct 21, 2026. Briefing in In re OpenAI finishes in November 2026. The DOJ filed a statement of interest on 2026-09-01 saying LLM training is "exceedingly transformative." There are no pending appellate rulings in these cases, so no cert-stage vehicle exists beyond ROSS. https://copyrightlately.com/thomson-reuters-v-ross-fair-use-generative-ai/
- [Timing arithmetic, my inference from the Supreme Court's published process] If ROSS skips rehearing, its cert deadline is 90 days after 2026-09-29, about Dec 28, 2026. A rehearing petition would push that later. The respondent normally has 30 days to respond, and then the petition is distributed for a conference. Thaler took about 5 months from filing to denial. A grant before Jan 1, 2027 would require a very fast petition, a waiver or expedited response, and a quick conference. That is highly unusual.
- [Base rate] Cert grants are rare, roughly 1% of paid petitions, and lower for interlocutory posture. In this reference class, the one AI-copyright petition that reached the Court was denied. I did not find a source quantifying the grant rate for 2026, so this figure comes from my background knowledge. The Court denied Thaler despite amicus support urging review. https://ipwatchdog.com/2026/03/02/supreme-court-denies-thalers-latest-attempt-register-copyright-ai-generated-image/
- [2026-10-12] Resolution risk: the market says "grants a writ of certiorari to a case about AI and copyright law." A broader reading could cover a tangential case, such as an AI-related copyright question inside another dispute. I found no such pending petition. The Court's 2025–26 copyright case was Cox v. Sony (DMCA/ISP), which is not about AI. https://www.law.berkeley.edu/research/bclt/bclt-legal-analysis/internet-computer-law-s1/
BOTTOM LINE: Historically, the only AI-copyright petition to reach the Court (Thaler) was denied after about 5 months, and the one live candidate (ROSS) is only about two weeks past an interlocutory Third Circuit ruling. The procedural calendar makes a grant before 2027 very unlikely, and the base rate for cert grants is low. Generative-AI cases are still in district court.
NOT FOUND: A filed ROSS rehearing or cert petition; any other pending AI-copyright cert petition; any published expert probability estimates for a SCOTUS grant by 2027; the market's own odds (deliberately not searched).
report: yes case
YES means: The Supreme Court grants a writ of certiorari, before Jan 1, 2027, in a case about AI and copyright law.
The strongest YES case is weak on timing. Only one path is live, and it needs the Court to move unusually fast.
- [2026-10-02] ROSS's counsel (White & Case's Yar Chaikovsky) publicly committed to seeking Supreme Court review of the Sept 29 Third Circuit ruling. His stated aim is "much-needed clarity" on AI-training copyright law. The statement was confirmed on a fetched page. This is the only declared intent to petition that I found. It is not a filed petition. https://www.lawnext.com/2026/10/ross-says-it-will-ask-supreme-court-to-review-3rd-circuit-ruling-for-thomson-reuters-in-copyright-case.html
- [2026-09-29] The Third Circuit opinion frames the case as "no more than an ordinary copyright case." It addresses both originality of the headnotes and fair use. Two questions of pure law give a petitioner a clean cert framing, and ROSS itself called them pure questions of law when it sought interlocutory appeal in 2025. The Court denied Thaler partly over vehicle problems (Thaler disclaimed any human contribution). This case has no comparable disclaimer. https://www2.ca3.uscourts.gov/opinarch/252153p.pdf
- [2026-10-12] Single most likely path to YES:
1. ROSS skips rehearing and files a cert petition within weeks, probably by early or mid-November.
2. Thomson Reuters waives its response or answers quickly. Alternatively the Court calls for a response and the petition is distributed fast.
3. The Court grants at a December conference, with the grant on an order list before Dec 31.
Each step is possible. I found no evidence any step has happened. https://www.supremecourt.gov/about/procedures.aspx
- [2026-10-12] Mechanism that helps YES: the Court's calendar runs through December. Its weekly conferences are held on Fridays during and preceding argument weeks, and it reviews about 130 petitions per week. A petition filed in early November with a waiver could be distributed for a December conference. Grants also come in January, but those fall after the window. https://www.supremecourt.gov/about/procedures.aspx
- [2026-10-12] Pressure for review: ROSS says the Third Circuit ruling leaves "continued uncertainty" over AI training. It is the first federal appellate ruling on AI-training fair use, which is the kind of question the Court usually waits for a split to address. Thaler's lawyer Ryan Abbott said in March that the Court "generally wait[s] for circuit splits." No split exists yet. A split would need a Ninth Circuit ruling in Bartz or Kadrey, and I found none pending. https://www.yahoo.com/news/articles/supreme-court-declines-ai-copyright-210345497.html
- [2026-08-16] Allen v. Perlmutter, the Midjourney authorship case, finished summary-judgment briefing in D. Colo. As of Aug 12 it had no merits decision. It is a district-court case with no appellate ruling, so it cannot reach cert in 2026. Abbott called it the likely next vehicle for the human-authorship question. https://rottenwifi.com/artist-appeals-copyright-denial-for-prize-winning-ai-generated-work-what-allen-v-perlmutter-could-decide/
- [2026-03-02] Thaler shows the Court was willing to take the AI-copyright question seriously enough to request a government response. Amici urged a grant, and commentators read the denial as "for now." That supports a later grant but not one before 2027. https://ipwatchdog.com/2026/03/02/supreme-court-denies-thalers-latest-attempt-register-copyright-ai-generated-image/
- [2026-10-12] Resolution wording favors YES slightly. The rule says only "a case about AI and copyright law." It does not require a generative-AI case or a final judgment. A grant in ROSS, a non-generative AI training case, would count. A grant in any tangential case involving AI and copyright might arguably count too. I found no such pending petition.
BOTTOM LINE: The only credible YES path is ROSS filing a fast cert petition and the Court granting at a December conference. That is a compressed schedule, and ROSS's interlocutory posture and non-generative AI make it a contested vehicle. I found nothing showing it has begun.
NOT FOUND: A filed ROSS cert petition or rehearing petition. A Supreme Court docket number for ROSS. Any scheduled conference on an AI-copyright petition before 2027. Any other pending AI-copyright cert petition. Any Ninth Circuit ruling creating a split. The web search tool hit its call limit, so I could not run further searches or check the Supreme Court docket directly.
report: no case
YES means: the Supreme Court grants a writ of certiorari, before Jan 1, 2027, in a case about AI and copyright law.
- [2026-10-02] ROSS has announced only an intent to seek review. A statement from its counsel at White & Case said "We intend to seek review". The announcement is not a filing. It came with a Third Circuit judgment dated 2026-09-29, so no petition was before the Court as of the sources I read. Commentary at chatgptiseatingtheworld expects the Court may call for the Solicitor General's views (a CVSG), because the DOJ did not file in ROSS. https://chatgptiseatingtheworld.com/2026/10/02/ross-intelligence-to-seek-supreme-court-review-of-third-circuits-decision-rejecting-fair-use-all-eyes-will-be-on-sgs-position/
- [2026-10-02] A CVSG would be the main bar to a 2026 grant. The Solicitor General in Thaler filed about 8 weeks after the call for a response (2025-11-26 to 2026-01-23, per the base-rate report). A CVSG usually takes much longer, because the SG's invited briefs typically arrive in the next briefing cycle. A DOJ position in ROSS is also uncertain: the DOJ's 2026-09-01 statement in In re OpenAI was favorable to AI training, and the Third Circuit opinion distinguished it. Same source as above.
- [2026-09-25] The Court had granted only one IP case for the October 2026 term so far: RiseandShine v. PepsiCo, a trademark case. Wolters Kluwer's IP docket preview lists no AI-copyright case among the grants. The preview was paywalled, so I could only read the summary. https://www.vitallaw.com/news/vital-briefing-supreme-court-s-ip-docket-for-october-2026-term-previewed/ipm01cf02e492233f4744bf8ee1cac51e5edb
- [2026-09-21] The Patently-O preview of the long conference (Sept 28) counted 13 patent petitions. It did not mention any AI-copyright petition. It said most petitions were awaiting responses. The long conference and the Oct 5 order list are past, so no AI-copyright petition was among those considered. https://patentlyo.com/patent/2026/09/patent-docket-heading-into-the-supreme-courts-long-conference.html
- [2026-09-13 approx., per ABA article dated 2026-09] An ABA Business Law Today piece published in September 2026 said district court proceedings in ROSS "remain stayed" pending the appeal. The case is therefore still interlocutory. The Court routinely denies petitions from non-final judgments, and the interlocutory posture has been cited as a reason to wait. https://www.americanbar.org/groups/business_law/resources/business-law-today/2026-september/thomson-reuters-v-ross-one-year-later/
- [2026-09-30] The Third Circuit's own opinion said its holding does not reach generative AI, per the chatgptiseatingtheworld summary, which quotes the footnote distinguishing the DOJ's Bartz-based argument. A narrow holding on non-generative AI weakens any circuit-split argument. No other circuit has ruled, so no split exists. https://chatgptiseatingtheworld.com/2026/10/02/ross-intelligence-to-seek-supreme-court-review-of-third-circuits-decision-rejecting-fair-use-all-eyes-will-be-on-sgs-position/
- [2026-03-02] Thaler is the precedent for a denial. The Court denied Thaler even though amici supported review and the question was a clean pure-law question with a final judgment below. The Court followed the SG's recommendation to deny. https://ipwatchdog.com/2026/03/02/supreme-court-denies-thalers-latest-attempt-register-copyright-ai-generated-image/
- [2026-03-06] The denial is a docket line, not a ruling, per Guadamuz at TechnoLlama. That matters for resolution: only a grant would count, and a denial does not. https://www.technollama.co.uk/no-the-us-supreme-court-did-not-declare-that-ai-works-cannot-be-copyrighted
- [Calendar arithmetic, my inference] Late-December and early-January conferences are the realistic last chances for a grant before 2027. Under the Court's rules, a petition filed in mid-October would get a 30-day response, which can be extended or waived. The Court usually distributes a petition about 14 days after the brief in opposition. A petition filed after Oct 12 would likely be considered in December or January. If a CVSG occurs, the grant date moves to 2027 or later. I did not confirm the Court's current conference calendar.
- [2026-10-12] Resolution-wording risk is small. The rule says "grants a writ of certiorari" and requires a "case about AI and copyright law". An announced intent, a filed petition, an extension request, a CVSG, or a distribution for conference does not count. Only a grant counts. A grant in Thomson Reuters v. ROSS would likely count, because the case concerns AI training and copyright.
- [2026-10-12] The generative-AI cases that could be better vehicles are all below appellate level. Bartz and Kadrey were N.D. Cal. rulings from June 2025 (per the CRS note in the earlier reports). Appeals decisions in them would not arrive in time for a grant before 2027.
BOTTOM LINE: For a Yes, ROSS would need to file within weeks, the SG would need to waive or skip a CVSG, and the Court would need to grant before year-end. It would also have to do this on an interlocutory, non-generative, no-split record, and no such petition has been reported filed. The status quo is no grant, and the only live candidate cannot move fast enough under the Court's ordinary process.
NOT FOUND: A filed ROSS petition, rehearing petition or extension application. A Supreme Court docket number for ROSS. Any CVSG in an AI-copyright case. Any other AI-copyright petition pending as of 2026-10-12. I did not read the Supreme Court docket directly.

The first round disagreed: the forecasts rest on claims no source in the evidence confirms: (1) No ROSS cert petition (or other AI-copyright petition) has been filed at the Supreme Court as of Oct 12, 2026; the Supreme Court docket was not checked directly for ROSS.; (2) No ROSS cert petition has been filed as of Oct 12, 2026 and no other AI-copyright petition is pending at the Supreme Court.

report: crux
CRUX: No AI-copyright cert petition appears to be pending, and ROSS, the only live candidate, is still at the rehearing stage in the Third Circuit. A grant before Jan 1, 2027 would need a petition to be filed, briefed and granted within about 11 weeks.
- **2026-10-02, ROSS announced a Supreme Court petition, not a filing.** A ROSS statement via White & Case says it "intend[s] to seek review by the Supreme Court." It reads as future intent. <https://www.lawnext.com/2026/10/ross-says-it-will-ask-supreme-court-to-review-3rd-circuit-ruling-for-thomson-reuters-in-copyright-case.html>
- **2026-09-29, the Third Circuit affirmed.** The affirmance was in No. 25-2153 (Restrepo, Montgomery-Reeves, Bove). It held the headnotes copyrightable and the use not fair, and the opinion was initially sealed. <https://www.authorsalliance.org/2026/10/02/third-circuit-affirms-in-thomson-reuters-v-ross-the-court-gets-merger-wrong-and-does-a-disservice-to-fair-use/>, <https://www2.ca3.uscourts.gov/opinarch/252153p.pdf>
- **Rehearing is still open, so the cert clock may not have started.** A CourtListener docket snippet shows an unopposed ROSS motion to extend time for a petition for rehearing en banc to 11/03/2026. <https://www.courtlistener.com/docket/70622297/thomson-reuters-enterprise-centre-gmbh-v-ross-intelligence-inc/?entry_gte=28&page=2>
- This is a snippet. I did not confirm it was granted.
- Under Supreme Court Rule 13, cert is due 90 days after judgment, or after rehearing is denied. <https://corp-intl.com/news/is-training-ai-models-fair-use-thomson-reuters-ross>
- Without rehearing, the deadline would be about Dec 28, 2026. With rehearing, it is later.
- **Claims (1) and (2) are only partly confirmed.** No source I found reports a ROSS cert petition filed, and the rehearing extension suggests none exists. I could not open the supremecourt.gov docket search directly, so "none filed" is not verified on the primary docket. I found no report of any other pending AI-copyright petition.
- **2026-03-02, Thaler v. Perlmutter (No. 25-449) was denied cert.** The petition was filed Oct 9, 2025, and the Court followed the Solicitor General's call to deny. This is the only AI-copyright cert action I found. <https://ipwatchdog.com/2026/03/02/supreme-court-denies-thalers-latest-attempt-register-copyright-ai-generated-image/>, <https://copyright.gov/ai/docs/us-reply-brief-in-opposition-to-pet-for-a-writ-of-certiorari.pdf>
- **ROSS is a weak vehicle on commentators' reading.** The ruling is the first appellate decision on AI-training fair use. It is limited because ROSS's tool was non-generative, and the generative-AI question is left open. <https://www.ballardspahr.com/insights/alerts-and-articles/2026/10/third-circuit-addresses-fair-use-in-ai-training-but-leaves-generative-ai-questions-unresolved>
- The case is interlocutory, and ROSS is shuttered. <https://copyrightlately.com/thomson-reuters-v-ross-third-circuit/>
- Calling the case "ordinary" is the Third Circuit's own framing, per Authors Alliance (see the 09-29 bullet).
- **Recentive Analytics v. Fox (No. 25-505) is a tangent.** It was a cert petition filed in Oct 2025 on AI and patent eligibility, not copyright. I did not check its outcome, and it is unlikely to count under this contract. <https://www.supremecourt.gov/DocketPDF/25/25-505/380165/20251021131338718_25-___PetitionForAWritOfCertiorari.pdf>
- **Timing.** From the dates above, Thaler took about 5 months from filing to denial. If ROSS filed in November or December, Thomson Reuters would normally have 30 days to respond, and an extension or a call for the Solicitor General's views is possible. That makes a December grant require unusual speed. This is my inference from the dates, not a sourced statement.
BOTTOM LINE: The evidence favours No, and strongly. The earliest plausible grant is well after the Jan 1, 2027 close, and the only AI-copyright case the Court has handled, Thaler, was denied. The residual risk is an unseen petition or an unusually fast ROSS filing and grant.
NOT FOUND:
- The supremecourt.gov docket search and orders pages, so "none filed" is unverified there.
- Confirmation that the Third Circuit granted ROSS's extension to Nov 3 for a rehearing petition.
- Any filed ROSS rehearing or cert petition.
- Any other pending AI-copyright cert petition, for example from the generative-AI cases.

(0) Nothing has resolved yet, and No is in effect locked in by the calendar. Thaler v. Perlmutter (25-449), the only AI-copyright petition to reach the Court, was denied on Mar 2, 2026, per the docket. The orders page through Oct 8, 2026 shows no AI-copyright grant. (a) About 11 weeks remain until Jan 1, 2027. (b) If nothing changes, no grant occurs and the market resolves No. (c) No path: ROSS uses its reported unopposed extension to Nov 3 to petition the Third Circuit for rehearing en banc, which delays the cert clock. Even a petition filed in November would face a 30-day response period, a likely call for the Solicitor General's views, and an interlocutory, non-generative-AI posture with no circuit split. Any decision would then come in 2027 or later; Thaler took about 5 months from filing to denial. (d) Yes path: ROSS skips rehearing and files in late October. Thomson Reuters waives its response and the Court grants at a December conference. Each step is unusual, and together they are very unlikely. A small extra chance comes from some unseen tangential AI-copyright petition being granted. The Kalshi price is 15% (bid 11 / ask 19, thin volume) and Polymarket is 12.5%. That pricing seems to reflect ROSS's announced intent to seek review rather than the procedural calendar. The rehearing-extension evidence and the timing arithmetic justify going well below the market.

(0) Nothing has resolved yet. The Supreme Court docket shows the only AI-copyright petition, Thaler v. Perlmutter (No. 25-449), denied on Mar 2, 2026. The Term 2026 orders through Oct 8 show no AI-copyright grant. A Yes still needs a petition to be filed, briefed and granted. (a) About 11 weeks remain until Jan 1, 2027. (b) If nothing changes, there is no grant and the market resolves No. (c) No path: ROSS seeks en banc rehearing in the Third Circuit (a CourtListener snippet shows a requested extension to Nov 3), which pushes its cert deadline into 2027. Or ROSS files a petition, Thomson Reuters takes its 30 days to respond, the Court calls for the Solicitor General's views or simply waits, and nothing is granted in 2026. (d) Yes path: ROSS skips rehearing and files by early November, Thomson Reuters waives its response, and the Court grants at a December conference. That would be a very unusual pace for an interlocutory case with no circuit split, involving non-generative AI and a defunct petitioner, after the Court passed on Thaler. Thaler took about 5 months from filing to denial. Kalshi trades at 15% (bid 11 / ask 19) and Polymarket at 12.5%. The recent rise looks like a reaction to ROSS announcing it will seek review. That is a statement of intent, not a filing, and the procedural calendar it implies makes a 2026 grant very hard. I therefore price well below the market at about 4%. The leftover probability covers an unseen pending petition or a broad reading of "AI and copyright."
