Who will be exercising the powers of the Venezuelan presidency on 31 December 2026?

TL;DR

I assign Delcy Rodríguez a 94% probability of exercising Venezuelan presidential powers at year-end (forecast calculation). Replacement by another Chavista is the largest alternative, at 4% (scenario model). Machado’s latest demand calls for elections by July 2027, beyond this question’s deadline (Reuters, October 9).

Context

This forecast uses information available by October 18, 2026, at 19:01 UTC, leaving about 74 days until December 31, 2026, at 23:59 ET. I apply the client’s substantive-power test: Maduro’s nominal legal status does not count as restoration, and an election announcement or declared victory does not count as a completed transfer (timing and resolution assumptions).

Rodríguez remains the starting incumbent. Reuters described her as acting president while reporting her televised announcement of energy agreements on October 17; a State Department letter dated March 10 expressly recognized her as the head of state able to act for Venezuela (Reuters, October 17; State Department letter, reproduced in court filings). A different outcome requires an actual transfer of executive authority, not just a dispute about her title.

Evidence

The historical backbone points toward watching insiders rather than voting intentions. In The Politics of Authoritarian Rule, published in 2012, Milan Svolik identified 205 insider removals among 303 clearly classified nonconstitutional authoritarian leadership exits over 1946–2008—68% of that sample (Cambridge University Press, chapter 1). This is a distribution of outcomes conditional on an irregular exit, not a probability that an incumbent falls during a particular period. It supports making another Chavista the leading alternative, but cannot supply a defensible Venezuelan departure rate by itself.

The strongest timing evidence comes from the transition process itself. The State Department’s October 9 fact sheet targets selection of 32 new Supreme Court judges by December and puts electoral-council reform in subsequent negotiating rounds. That describes unfinished institutional preparation, not an imminent inauguration (State Department fact sheet, reproduced by Forth). Reporting published October 17 quotes opposition negotiator Dinorah Figuera expecting the foundations for an electoral process to be established before year-end, while disqualifications, electoral-authority renewal and an election date remain under discussion (EFE reporting via Infobae, October 17). My inference is that a conventional election, certification and handover is very unlikely to finish before the deadline. An accelerated negotiated installation remains a separate possibility.

Washington’s recent behavior favors continuity. In an interview conducted September 28 and published October 1, Trump praised cooperation with Rodríguez and said elections were premature (TIME transcript). Treasury then removed Jorge Rodríguez from its sanctions list on October 14 (OFAC notice). I read the combination as investment in the existing negotiating arrangement, not preparation for an immediate executive replacement. Neither action binds future policy.

There is evidence of executive authority, but less evidence of personal control over every armed institution. Reuters reported Rodríguez’s March 18 replacement of Defense Minister Vladimir Padrino with Gustavo González López, a consequential personnel decision (Reuters, March 18). Cabello’s own outlet recorded his October 13 support for her government and the dialogue process (Con el Mazo Dando, October 13). The first observation supports her capacity to govern; the second establishes public accommodation. Neither proves that commanders would obey her during an elite confrontation.

That distinction matters because institutional continuity cuts both ways. Following its official visit, Human Rights Watch reported reduced overt repression but emphasized that the underlying machinery remained intact (Human Rights Watch, September 18). I interpret this as evidence against treating the government as a wholly new, personally unified administration. It preserves the possibility that established security actors could coordinate an internal succession.

Maduro faces a different set of barriers. AP’s October 15 court report places him in U.S. custody and reports a trial scheduled for June 14, 2027 (AP, October 15). A restoration would require an exceptional release arrangement and renewed executive command inside Venezuela. Release or continued claims to the presidency alone would not satisfy the client’s criteria.

I translate this evidence into a judgmental scenario-mixture model. The scenarios allow the visible accommodation to persist, concealed friction to become consequential, or an acute crisis to change the governing arrangement. The following weights, departure intensities and replacement allocations are my assumptions, not measured historical frequencies (complete calculation).

The incumbent probability is calculated as $P(D)=\sum_s w_s e^{-\lambda_s T}$, where $w_s$ is each scenario’s weight, $\lambda_s$ is its effective departure intensity in transfers per leader-year, and $T$ is the remaining exposure in years. Each scenario’s departure probability is distributed across the alternatives using the listed allocations. The intensities apply only to this forecast window; they are not predictions for the following full year (model definitions and results).

This produces the reported 94% incumbent probability. Changing the acute-crisis weight from 1% to 15%, while offsetting the consolidation weight, moves Rodríguez’s probability from 96% to 90%. That is assumption sensitivity, not a statistical confidence interval. The additional decimal places in the JSON preserve the calculation, not equivalent precision about political risk; prediction-market prices receive no weight (calculation and sensitivity).

What's non-obvious

Progress toward eventual democratization can strengthen Rodríguez’s position over this short horizon. Court reconstruction and electoral guarantees make her administration the counterparty responsible for implementing the next steps. The December judicial milestone is therefore more informative than the mere absence of an election announcement: it supplies positive evidence that important prerequisites are still scheduled near the deadline (State Department’s stated sequence). This is my inference, not a guarantee that the sequence cannot be bypassed.

Legal vulnerability is also not an automatic succession mechanism. AP reported that Rodríguez remained in office after her initial temporary appointment expired (AP, April 6). The relevant question is whether another actor can coordinate a transfer that ministries and armed institutions obey. Constitutional objections and electoral popularity matter through that mechanism; they do not themselves exercise presidential powers.

Uncertainties

The largest gap is independently verified command loyalty. Public endorsements, appointments and diplomatic activity do not reveal whose orders would prevail during a confrontation. I could not establish a complete current military-security command map or authenticate an exhaustive current TSJ and electoral-authority record. Nor can public reporting rule out a private succession bargain. Those limits justify retaining a meaningful surprise-removal allowance.

The most useful missing evidence would be an independently corroborated test of presidential command, or a signed agreement specifying an executable transfer before the deadline. Senior commanders rejecting her orders, a coordinated alternative leadership coalition, or Washington conditioning continued cooperation on her departure would sharply lower the estimate. Further dialogue, an undated election promise, or an opposition leader’s return without a transfer of authority would be much weaker updates under this question’s substantive-power test.
