US strike on Cuba by December 31?

- [2026-01-03/04] US forces struck Venezuelan military bases and captured Maduro. Trump then said Cuba could collapse and said "make a deal." This is the precedent for US strikes in the region. No US strike on Cuban soil has been reported in any source I found. https://www.yahoo.com/news/articles/cuba-left-reeling-aftermath-venezuela-024033192.html - [2026-03-27] Trump said "Cuba is next, by the way. But pretend I didn't say that." Mid-March he spoke of "taking Cuba in some form." https://www.malaymail.com/news/world/2026/03/28/trump-warns-cuba-is-next-denies-losing-maga-support/214238 - [2026-05-22] Raúl Castro was indicted, and the USS Nimitz group entered the Caribbean. Rubio and Trump renewed military threats. Rubio called a negotiated settlement unlikely (2026-05-21). https://www.aljazeera.com/news/2026/5/22/us-raises-threat-of-military-action-against-cuba - [2026-07-15 approx.] CBS reported Pentagon options, including a 101st Airborne air assault, from a late-June briefing. Officials said no decision had been made. They said an attack was unlikely near-term because of the renewed Iran war. https://www.latintimes.com/pentagon-reportedly-developing-military-strike-options-against-cuba-trump-ramps-pressure-havana-598253 - [2026-09-22] At the UN, Trump demanded "fundamental change" in Cuba and said its government "will fall." The Cuban delegation walked out. On 2026-09-23 Rubio said the US is open to talks on a political transition. https://www.aljazeera.com/news/2026/9/23/us-says-it-is-open-to-talks-with-cuba-if-it-changes-government - [2026-09-26] CBS (fetched) reported an Army Reserve message asking about support units (military police, medical, logistics) "possibly needed in 90-120 days." That window runs to roughly late December through January. There is no indication of deployment orders. Trump said on 2026-09-26: "Cuba and us will make a deal. I don't think we'll need the military." CBS also reported earlier-this-year US reconnaissance and airpower pre-staging "did not come to fruition." https://www.cbsnews.com/news/u-s-groundwork-potential-action-cuba-trump/ - [2026-09-29/30] Rubio on Fox warned Cuban leaders they will "learn the lesson the hard way" if they wait the US out. https://www.latinpost.com/articles/167564/20260930/rubio-cuba-stop-waiting-us-out-learn-lesson-hard-way.htm - [2026-10-06] Reuters (fetched): Cuba's chargé in Washington said there are "channels of communication" but no formal talks. The State Department says talks are ongoing. The US tightened the embargo in the last days of September. Cuba is increasing its defensive preparations. https://www.jpost.com/international/article-910730 - [2026-10-02 to 10-07] Reuters headlines: the US Coast Guard intercepted a fuel ship bound for Cuba (10-02), and the US seized $3M in fuel shipments (10-07). The pressure is blockade and interdiction, not kinetic action. https://www.usnews.com/topics/locations/cuba - [2026-10-12] Al Jazeera/Reuters: the oil blockade continues, and Cuba is pressing on with renewable energy plans. https://www.aljazeera.com/amp/economy/2026/10/12/cuba-forges-ahead-with-renewable-energy-plans-amid-us-oil-blockade - [2026-10-16] CBS: the grid is near collapse and the administration "wants to remove Cuba's regime." The economic campaign is ongoing, and there is no report of a strike. https://www.cbsnews.com/news/us-embargo-sanctions-cuba-power-medicine/ - [2026-10-13/17] The US is also engaged in the Iran war (renewed in July). Trump threatened on 10-13 to "hit Iran hard." This competes for military resources. https://www.jpost.com/international/article-911627 BOTTOM LINE: As of 2026-10-17 there has been no US strike on Cuban soil. The US is running a blockade, sanctions and contingency planning, and that planning includes a reported 90-120 day readiness window ending around late December to January. Trump publicly favors a "deal" while keeping threats open, and Iran absorbs military capacity. NOT FOUND: Any report of an actual US strike on Cuba. Any scheduled deadline or ultimatum date before 12-31. Any confirmed deployment orders. Any 10-14 to 10-17 military-specific development beyond the blockade and sanctions items above.

- [2026-10-16] Polymarket's own broader market, "US military action against Cuba by…?", shows the Dec 31 outcome at about 12%. Its summary says Trump is downplaying military action and that commanders report no active invasion preparations. No US strike on Cuban soil has happened in 2026 so far. The market opened on 2026-01-04 and has about $7.6M volume. This is the same event family as the question, but the criteria may differ. https://polymarket.com/event/us-strike-on-cuba-by - [2026-05-27] Benzinga reported Polymarket at 49% for a US drone, missile or air strike on Cuba before year-end, up from 15% a month earlier. That was the peak, set during the USS Nimitz deployment. The price has since fallen to about 12%, and the May peak did not turn into a strike. https://www.benzinga.com/markets/prediction-markets/26/05/52709065/will-trump-strike-cuba-prediction-market-uss-nimitz - [2026-03-11] Polymarket put a "military clash" at 44% and a US invasion of Cuba in 2026 at 20%. Early-year pricing was therefore well above the current level without any strike occurring. https://en.cibercuba.com/noticias/2026-03-11-u1-e13-s27061-nid322825-apuestas-internet-ponen-precio-caida-regimen-cubano-2026 - [2026-10-07] A separate Polymarket market, "Will the U.S. invade Cuba in 2026?", is at about 5%. Its description cites Trump saying military action is unnecessary and Southern Command denying invasion rehearsals. https://polymarket.com/event/will-the-us-invade-cuba-in-2026 - [2026-09-26] Trump said "I don't think we'll need the military" and expects a deal with Cuba. This followed a CBS report of military preparations for action in a "90-120 day" window, and a report that the Army Reserve was laying groundwork over about four months. That window runs to roughly late January 2027. https://www.ibtimes.co.uk/trump-us-cuba-deal-military-action-unlikely-1822105 and https://www.wsws.org/en/articles/2026/09/28/qkuv-s28.html - [2026-05-22] Trump said he looks likely to be "the one that does it", and Rubio warned Cuba cannot wait the US out. The US had indicted Raúl Castro and gathered forces in the Caribbean, including the Nimitz group. Rhetoric peaked in May with no strike followed. https://www.aljazeera.com/news/2026/5/22/us-raises-threat-of-military-action-against-cuba - [2026-09-23] Rubio said the US is open to talks if Cuba moves toward a political transition. The US pressure campaign is mainly an oil blockade plus sanctions. https://www.aljazeera.com/news/2026/9/23/us-says-it-is-open-to-talks-with-cuba-if-it-changes-government - [2026-10-16] A Cuban diplomat confirmed contacts with the US but said there is no progress toward formal dialogue. Havana calls regime change a red line. Reports say talks stalled when Washington demanded that Díaz-Canel be removed. https://en.cibercuba.com/noticias/2026-10-16-u1-e135253-s27061-nid343025-diplomatica-regimen-confirma-contactos-eeuu-descarta - [2026-10-15] Cuban exiles in Miami are frustrated that the "invasion" never came. Midterms are on Nov 3. This suggests political pressure to act, but also shows nothing has happened. https://en.cibercuba.com/noticias/2026-10-16-u1-e199894-s27061-nid342997-euforia-decepcion-exiliados-cubanos-miami-vuelven - [2026-08 approx.] The American Security Project judged military action unlikely before the November midterms but a post-election operation "highly probable". This is one expert view, and I could not fetch the page (403). Its date is only inferred from the "72 days ago" tag in the search result. https://www.americansecurityproject.org/will-the-us-take-military-action-against-cuba/ - [2026-01-03] Reference class: the US captured Maduro in Venezuela on Jan 3 in a strike that killed 32 Cuban security personnel. It has also carried out boat strikes under Operation Southern Spear. Trump therefore has precedent for acting on rhetoric. Even so, the Cuba threats have run for about 9.5 months without a strike on Cuban soil. https://en.wikipedia.org/wiki/2026_in_Cuba BOTTOM LINE: The outside view is a heavily threatened but so-far-unstruck target. Market pricing has fallen from roughly 49% in May to about 12% now, and Trump is publicly signalling a preference for a deal. Reported military planning windows and a possible post-midterm timing leave a modest tail risk, and only about 11 weeks remain before the deadline. NOT FOUND: Any historical base rate for US strikes on Cuban soil; Kalshi or other venues' Cuba strike prices; reporting of a confirmed US strike on Cuban territory in 2026; the full text of the CBS report; and the American Security Project's full text (403 error).

YES means: a US-initiated drone, missile or air strike physically hits Cuban ground territory, and the US announces it or credible reporting confirms it, by 2026-12-31 ET. Intercepted missiles, naval shelling, ground raids and cyberattacks do not count. - [2026-10-06] The Atlantic, as relayed by CiberCuba (fetched), reports the US-Cuba backchannel stalled because Washington made Díaz-Canel's departure non-negotiable and Havana refused. The Atlantic says the main reason for the halt is that the Iran war tied up carriers and warplanes. With diplomacy dead-ended, force is the only remaining step on the US escalation ladder. The restraint described is one of capacity, not intent. https://en.cibercuba.com/noticias/2026-10-06-u1-e207888-s27061-nid342082-conversaciones-cangrejo-rubio-estancaron-condicion - [2026-10-06] The same Atlantic account says the US offered fuel and aid in exchange for privatizing the energy sector, and that Cuba formally rejected it. Rubio's UN language was softer, but he told Hannity that "Cuba has already fallen." Rosa María Payá doubts Rubio has final decision power. A YES path therefore depends on Trump personally, not on the diplomats. https://en.cibercuba.com/noticias/2026-10-06-u1-e207888-s27061-nid342082-conversaciones-cangrejo-rubio-estancaron-condicion - [2026-10-03] SOUTHCOM announced that Guantánamo will host the first site of its Autonomous Warfare Command. The command was created 2026-04-21, and General Donovan observed unmanned-system deployments there. The US already has a drone-capable base on the island and an organization built for unmanned strikes, so a limited drone strike would not need a visible buildup. https://en.cibercuba.com/noticias/2026-10-03-u1-e207888-s27061-nid341799-drones-suelo-cubano-eeuu-convierte-base-naval - [2026-10-01/03] SOUTHCOM posted that the 82nd Airborne can deploy "within 18 hours" in its region. The post did not name Cuba, and as of 10-03 there was no deployment order. It is a signalling item, not a trigger. https://www.riotimesonline.com/southcom-82nd-airborne-message-cuba-2026 - [2026-10-04/09] SOUTHCOM resumed lethal boat strikes on 10-04, killing four. That brings the campaign to at least 70 strikes and 235 deaths since September 2025. The command is still using lethal force routinely in the Caribbean, and the Iran war has not stopped this. These are maritime strikes and would not count for this market. https://www.wsws.org/en/articles/2026/10/10/uihm-o10.html - [2026-10-09] Cuba-bound biodiesel (90 shipments) was seized at Port Everglades and Houston, the second fuel seizure in a week. Cuban officials call the seizures "piracy." The blockade is tightening, and grid failure with 20-hour blackouts could produce unrest or a pretext. https://www.wsws.org/en/articles/2026/10/10/uihm-o10.html - [~2026-07-15] CBS says Pentagon planners developed options in a late-June briefing, and Hegseth said he presented options to Trump. CBS also said an attack was unlikely in the near term because of Iran. It noted that Cuba had acquired attack drones of unknown origin, and Hegseth warned Cuba would be "inviting the kind of confrontation" it "could not stand" if it acquired certain capabilities. A Cuban drone or Russian/Chinese asset move is a possible pretext for a limited strike. https://www.cbsnews.com/news/cuba-military-options-pentagon/ - [~2026-08] The American Security Project (snippet only) judged action unlikely before the midterms but a post-election operation "highly probable." It said the US "could realistically conduct a limited strike" in the short term, while an invasion needs a visible buildup. Three carriers are within deployable range by year-end. The post-Nov-3 window leaves about eight weeks before the deadline. https://www.americansecurityproject.org/will-the-us-take-military-action-against-cuba/ - [2026-09-26] The CBS Army Reserve request for support units within four months covers military police, medical, engineer and sustainment units. Those units look like stabilization or occupation support. Any such operation would very likely be opened with air or missile strikes, which would resolve this market YES. No deployment orders exist (CBS). https://www.cbsnews.com/news/u-s-groundwork-potential-action-cuba-trump/ - [2026-09-28] WSWS, citing the New York Times, says Trump advisers believed the Cuban government "could be gone by the time of the midterm election." That did not happen. If the regime survives November, advisers' expectations are unmet and pressure for a kinetic option rises. This is a secondary relay of the NYT. https://www.wsws.org/en/articles/2026/09/28/qkuv-s28.html - [2026-10-06] Miami exile frustration at nine months of "unfulfilled promises" is documented by The Atlantic. It is a domestic political cost of inaction, but a weak driver. https://en.cibercuba.com/noticias/2026-10-06-u1-e207888-s27061-nid342082-conversaciones-cangrejo-rubio-estancaron-condicion **Most likely path to YES:** The talks stay stalled and the grid and economy keep deteriorating. After the Nov 3 midterms, Trump orders a limited air or drone strike, or the opening strikes of a larger operation. Targets would be military or GAESA-linked sites, air defenses, or sites tied to Cuba's drones or foreign-power assets. Prerequisites: 1. Iran forces freed up, or a limited strike that needs few assets. 2. A trigger or pretext, or Trump's decision that the blockade has failed. 3. Cuba's refusal of the Díaz-Canel demand. The strike would also have to occur by 12-31. BOTTOM LINE: The YES case rests on a stalled diplomatic track, a tightening blockade, a drone-ready Guantánamo base and post-midterm planning timelines. The Iran war is the main constraint, and Trump's public stance prefers a deal, with no strike reported so far. NOT FOUND: Any report of an actual US strike on Cuban soil; a deployment order or dated ultimatum before 12-31; a fetched full text of the American Security Project piece (snippet only); any confirmed Cuban pretext event such as a drone attack on Guantánamo.

YES means: a US-initiated drone, missile or air strike that physically impacts Cuban land territory (not intercepted, not naval or artillery fire, not a ground incursion) is announced or credibly reported to have occurred by Dec 31, 2026 ET. - [2026-10-15] Rubio's newest Cuba action was a sanctions designation, not a military step. The state bank Banco Internacional de Comercio was sanctioned for services to Iran's Karafarin Bank, and Rubio said Washington would keep dismantling Cuba's financial and security links with Iran. I fetched this page. The tool in use is Treasury and State, and this is the most recent official US Cuba action I found. https://thenationalnews.com/news/us/2026/10/15/marco-rubio-accuses-cuba-of-helping-iran-and-other-malign-actors-to-attack-us - [2026-09-25] I fetched a legal analysis of the CBS "90-120 days" report. It says the Army message did not mention Cuba, contained no deployment orders, and did not say where forces would go. The analysis calls the window a force-availability window, not a timetable for an invasion. The same piece says that as of 9/25 nothing public shows an authorized attack, a presidential order or a fixed date. This weakens the reading that the window means action by late December. https://www.diplomacyandlaw.com/post/cuba-invasion-u-s-military-planning-and-international-law - [2026-09-25] The same analysis records SOUTHCOM commander Gen. Donovan's March Senate testimony. He said SOUTHCOM was not rehearsing a plan to seize Cuba, and its stated Cuba tasks were Guantanamo, embassy and personnel protection, and mass-migration support. Even the CBS July options were framed as a concept-of-operations briefing, with officials stressing no decision had been made. https://www.diplomacyandlaw.com/post/cuba-invasion-u-s-military-planning-and-international-law - [2026-10-01/02] Iran is absorbing forces, and the build-up runs through the end of the contract window. WaPo reported a possible Middle East naval surge, with Trump weighing renewed Iran strikes after the midterms. A third carrier group, Theodore Roosevelt, left San Diego with the Makin Island amphibious force and 2,000 Marines. WSJ, via CNBC, said the build-up would finish by November. The Marines and a carrier that could have gone to the Caribbean are going to the Gulf. I could not fetch these pages, so this rests on search snippets. https://www.cnbc.com/2026/10/02/us-iran-war-trump-hormuz-.html - [2026-10-16] Iran operations are still active. CENTCOM was disputing Iranian claims about Hormuz on 10/16, and Hormuz ship attacks were rising on 10/13. The post-midterm window the administration would use for Iran is also the window any Cuba action would need. Two simultaneous fights are costly. https://gulfnews.com/world/mena/middle-east-conflict-us-destroys-iranian-linked-dhow-as-tehran-shifts-tactics-near-hormuz-1.500711139 - [2026-07-16] CBS said officials thought a Cuba operation unlikely near term. The Pentagon had moved aircraft and intelligence assets to the Middle East for Iran, and any Cuba operation would hit capacity committed elsewhere. Rubio's preferred path is a diplomatic, technocrat-led transition. That diplomacy stalled but was not abandoned. https://www.cbsnews.com/news/cuba-military-options-pentagon/ - [2026-10-15] Reporting on the exile frustration says the Rubio-to-"El Cangrejo" back-channel stalled over Díaz-Canel's removal, and that nine months after the January 3 Maduro raid there has been no military action. A stalled back-channel is not a trigger for force. Washington is applying economic pressure and making maximalist demands. https://en.cibercuba.com/noticias/2026-10-16-u1-e199894-s27061-nid342997-euforia-decepcion-exiliados-cubanos-miami-vuelven - [2026-10-16] The Cuban Embassy's deputy chief confirmed contacts with Washington and said Havana is open to talks without preconditions. This is a live diplomatic channel, which fits Trump's stated preference for a deal. https://www.cubaheadlines.com/articles/343025 - [2026-09-27] Fernández de Cossio said the US has been squeezing Cuba for "nine months now" through a de facto oil blockade, and Havana is preparing for aggression. The same Al Jazeera piece quotes Trump saying "I don't think we'll need the military." The coercion regime is already working through economic channels. Cuba's grid is collapsing, so the US has less reason to risk costs from force. https://www.aljazeera.com/news/2026/9/27/atrocious-crime-cuban-official-decries-possibility-of-us-military-action - [2026-08 approx.] The American Security Project, by its own text, judged military action before the midterms unlikely and a post-election operation "highly probable". It also said US forces were constrained by the Iran war. Its timing is only inferred (a "72 days ago" tag in the search result). The post-election timing leaves about 8 weeks before Dec 31. Planning and moving forces for an air assault and military police would take longer than that. https://www.americansecurityproject.org/will-the-us-take-military-action-against-cuba/ - [2026-10-16] The criteria technicalities cut against a Yes. Only air, drone or missile impacts on land count. A naval interdiction, a Guantanamo-based action, a ground raid, a special-forces operation without an air strike, or a sea or fuel-ship strike would not qualify, and the criteria exclude naval shelling. The Coast Guard and fuel-ship interdictions at sea (reported on 10/02 and 10/07) do not count. A blockade escalation, which is the expected next step, would not resolve Yes. The market also resolves No if the date of a strike cannot be confirmed by the end of the second day after the resolution time. https://www.cbsnews.com/news/us-embargo-sanctions-cuba-power-medicine/ - [2026-05 to 2026-10] The record of threats that did not become strikes is long. CBS (via Raw Story, 9/25) said US air units were placed on heightened readiness and seafloor surveys were done earlier in 2026, but those plans were not carried out. The May Nimitz build-up, the Raúl Castro indictment, and Trump's "Cuba is next" remarks did not become strikes either. https://www.rawstory.com/donald-trump-war-cuba-new/ BOTTOM LINE: The No case rests on status quo and on timing. Only about 10 weeks remain, nothing shows an authorized order, and the pressure is economic and diplomatic. Iran is taking carriers, Marines and attention through November. The 90-120 day window is only a reported availability check, and Trump publicly says he does not expect to need the military. Even an operation that did happen would have to include a land-impacting air, missile or drone strike to qualify. NOT FOUND: Any report of a US strike on Cuban soil. Any scheduled ultimatum before 12-31. Any deployment orders or a 101st Airborne move. Any Caribbean carrier deployment in October. Any fetchable primary Pentagon or White House statement setting a Cuba timetable. I could not fetch the WaPo and CNBC pages (they errored), and the CBS 9/25 and ASP pages were not fetched in full by me.
