The Quiet Opening: Washington, Havana, and the 26% Chance of History Repeating

The market does not believe it will happen. As of 21 May 2026, Polymarket — the blockchain-prediction platform that has become a favoured instrument for traders sizing geopolitical risk — placed the probability of a US-Cuba economic deal by the end of the following month at 26 percent. Twenty-six cents on the dollar. Not zero, but not close to a coin flip. It is the kind of number that rewards contrarians or punishes optimists, depending on who is reading it.

The timing is not accidental. Polymarket's contract settled on the back of a slow thaw that has been underway since the Biden administration's quiet reversal of some of the most punitive Trump-era restrictions on family remittances and charter flights. That thaw has continued, fitfully, into 2026. But the word "deal" implies something more formal — a diplomatic architecture, not just an administrative softening. And that raises a question that has shadowed Washington for sixty-seven years: what does a successful US policy toward Cuba actually look like?

The record is not encouraging. From the Platt Amendment to the embargo, from the Bay of Pigs to the Helms-Burton Act, from the Cuba normalization under Obama to its reversal under Trump, the United States has cycled through the full spectrum of carrots and sticks without producing a policy that achieved its stated goals. Havana's Communist Party remains in power. The island's economic model — whatever its dysfunctions — has not collapsed. The US has spent decades trying to engineer an outcome it could not define, let alone deliver.

This history does not make a 2026 deal impossible. It does, however, demand that any serious assessment of the odds begin with an honest accounting of what has failed before and why — and whether the structural conditions that sank previous openings have materially changed.

The Architecture of Failure

To understand the present moment, it is necessary to understand what Washington has been trying to do for the better part of a century. The stated objective has varied: democracy, regime change, human rights compliance, the return of American-owned property seized after the 1959 revolution. The instruments have been more consistent. The embargo — a comprehensive commercial and financial blockade that constrains not only US firms but any company worldwide that wishes to do business with the United States — has been the primary tool since 1960. It was hardened into law with the Torricelli Act in 1992 and the Helms-Burton Act in 1996, the latter of which extended its reach extraterritorially, drawing protests from the European Union and Canada.

The effect, by most independent assessments, has been the opposite of the stated intent. The embargo strengthened the Castro government's principal grievance against Washington and gave it a convenient explanation for economic hardship that had more to do with centrally planned dysfunction than with American sanctions. It also provided a reliable framework for rallying nationalist sentiment. Every tightening of the embargo, whether intended as punishment or as leverage, was read in Havana as proof that the United States would never accept Cuban sovereignty on its own terms — and therefore that any accommodation with Washington was a trap.

Obama's 2014-2016 opening — restoring diplomatic relations, easing travel restrictions, expanding telecommunications exports — was the most sustained effort at normalization in the post-Cold War period. It produced measurable but modest economic benefits and was accompanied by a private diplomatic channel through which both governments discussed issues including human rights, political prisoners, and maritime boundaries. The Trump administration dismantled all of it by 2019, reimposing restrictions that Biden partially reversed but never fully restored.

The pattern is familiar enough that it has become a subject of study in its own right. Each US administration arrives with a theory about what leverage can achieve. Each eventually discovers that leverage, applied to a small island with a resilient political class and a network of alternative patrons, produces a different outcome than the theory predicted.

The New Interlocutors

What is different in 2026? The most immediate change is not in Washington or Havana but in the surrounding geopolitical terrain.

Venezuela, Cuba's closest ideological ally and the source of the subsidised oil that has sustained parts of the Cuban economy for two decades, is in a state of managed instability. The survival of Nicolás Maduro's government — against repeated US sanctions and the withdrawal of recognition by Washington and a bloc of Western democracies — has required Havana to work harder at maintaining its traditional network. It has done so in part by deepening commercial ties with China, Russia, and a range of Gulf and Southeast Asian states. The island is less isolated than it was in 2016, even if its economic situation remains severe.

China's presence is the most structurally significant development. Chinese investment in Cuban infrastructure — particularly in ports, telecommunications, and energy — has grown steadily. The relationship is not primarily ideological; it is transactional, rooted in China's interest in having a reliable partner in the Caribbean, a region the US has historically treated as its exclusive sphere of influence. For Havana, the Chinese connection offers something the US has always withheld: investment without political conditions, trade without the periodic threat of contraction.

This matters for any US opening because it changes the leverage calculus. In 2014, Cuba needed a deal with Washington more than it needed an alternative. In 2026, it has options. Not good ones, necessarily — Chinese investment comes with Chinese expectations, and the Cuban economy remains in structural crisis regardless of its foreign partnerships — but options that reduce Havana's incentive to accept terms it would have rejected a decade ago.

The Domestic American Picture

Washington's room for manoeuvre is constrained by its own domestic politics in ways that often go underappreciated in accounts focused on the bilateral relationship.

The Cuban-American constituency in south Florida — concentrated in Miami-Dade County, historically a swing area in Florida's electoral math — has exercised disproportionate influence over US Cuba policy for reasons rooted in the exile community's particular history and its organisational capacity. The exile establishment, particularly the older generation that left Cuba after the revolution, has been uniformly hostile to normalisation and has punished politicians of both parties who appeared to move toward accommodation. The Republican Party's hardening on Cuba under Trump, reinforced by a politically useful association between Havana and left-wing governments across Latin America, has made any significant reversal a potential electoral liability in a state that has voted Republican in five of the last six presidential elections.

The calculation looks different if the political context changes. Florida's demographic composition is shifting; the Cuban-American community is not monolithic, and younger voters have shown less attachment to the hardline positions of their grandparents' generation. The semiconductor and reshoring industries that have become central to Biden-era and subsequent industrial policy have created constituencies in Washington that see Cuba's geographic position — ninety miles from Key West — as an asset rather than a threat, particularly for supply chain and logistics considerations that the Cold War framing obscures.

These domestic shifts do not add up to a consensus in favour of a deal. They do, however, suggest that the political floor beneath which US Cuba policy cannot fall has shifted, even if the ceiling remains low.

The Stakes of Getting It Wrong — Again

The question of what success would look like is where most US Cuba policy discussions quietly collapse. The Helms-Burton Act defines success as the replacement of Cuba's government with a US-aligned democracy. That is not a policy; it is a fantasy, and treating it as a benchmark ensures that any partial accommodation can be characterised as failure by those with political incentives to do so.

A more limited definition — increased commercial activity, expanded travel, normalised diplomatic relations, reduced human rights frictions on both sides — is achievable. It has been achieved before. What has not been achieved, in sixty-seven years of trying, is the thing US policy has always actually been about: controlling the outcome in a country ninety miles from Florida. That goal is incompatible with Cuban sovereignty as the Cuban government understands it, and there is no evidence that the current government in Havana, or its successor, would accept terms that required them to abandon it.

The stakes of getting this wrong again are asymmetric. Another failed opening — one that produces symbolic gestures, a brief increase in tourism revenue, and then a reversal under the next administration — would hurt ordinary Cubans most acutely. The humanitarian costs of the embargo, documented by UN agencies and international aid organisations, fall on the population rather than the government. A policy that continues to use economic pressure as its primary instrument while the target government remains in power will continue to produce the same result it has always produced: suffering without strategic effect.

The alternative — a sustained, structured engagement with clear and limited objectives — carries its own risks. It would require Washington to accept that the Cuban government will not change in the ways it wants, and to pursue interests that remain achievable even in the absence of regime change. That is not a surrender. It is a recognition of reality. Whether the current administration in Washington, or the political coalitions that constrain it, is capable of making that distinction is what the Polymarket market is, in its indirect way, trying to price.

Twenty-six percent says it cannot. The history it is pricing against is not encouraging. But history, as every analyst who has written about US-Cuba relations eventually notes, is also written by the people who got it right the first time they tried. No one has tried this particular version yet.
