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

TL;DR

Delcy Rodríguez has an 87% chance of exercising Venezuela's presidential powers at the deadline. The main alternative is another Chavista figure at 7%, through an internal elite or security-sector replacement. María Corina Machado's popularity does not overcome the lack of a workable pre-deadline election path in the current transition timetable.

Context

Rodríguez has exercised executive power since her January 5, 2026 swearing-in. By August 30, she had outlasted the original 90-day legal window and gained US recognition as Venezuela's sole head of state, and she had been removed from the sanctions list on April 1. On March 18, she replaced defense minister Vladimir Padrino López after his 11 years in the post; on August 4, the National Guard commander publicly demanded loyalty to her.

The question asks about de facto control, not Maduro's residual legal claim. That makes the near-term contest simple: Rodríguez remains unless an elite rupture, a forced US-backed transfer, death or incapacity, or state breakdown removes her. The short horizon favors continuity because no replacement process is close to completion.

Evidence

The historical backbone points to high persistence, but not certainty. Archigos 4.1, released on March 1, 2016, contains 3,409 leader spells across 188 countries from 1875 through 2015. In my complete-window calculation, 90.3% of the 2,613 leaders who had already served 237 days remained in office for the next 123 days. The closest small cells gave 88.9% survival for personal dictators who entered irregularly or through foreign imposition, N=54, and 92.0% for post-1946 successors whose predecessor was removed with foreign force, N=25. REIGN's final August 2021 release, covering roughly 137,000 leader-months in 201 countries from January 1950 through August 2021, gave 90.0% four-month survival for personal dictators at six months in office, N=110, and 85.5% for all autocrats, N=683. These old datasets do not know Venezuela's current facts, but they put the neutral prior near 89%.

Foreign-backed successions deserve a risk premium. Research on 120 foreign-imposed regime changes from 1816 through 2008 finds that imposed leaders face more irregular removal over their full tenure, especially when intervention changes the ruler but leaves weak institutions behind (Alexander Downes, 2021). That result is long-run and cannot be applied mechanically to four months. Rodríguez is also not a pure foreign implant: she was Maduro's vice president and inherited an intact Chavista state.

The strongest Venezuela-specific evidence favors Rodríguez. Her dismissal of Padrino showed that she could remove the military's longest-serving power broker without a visible mutiny (Reuters, March 18). Her government deported Maduro ally Alex Saab to US custody on May 16, a costly break with Maduro's network. The US then shielded her working relationship by delisting her and, according to AP's May report, directing prosecutors to avoid steps that could disrupt stabilization under her. On August 25, she chaired a security meeting attended by Interior Minister Diosdado Cabello, Defense Minister Gustavo González López, the National Guard commander, and senior police officials.

The August oil announcement strengthens continuity, but less than the headline implies. Trump publicly named Rodríguez as the Venezuelan counterparty in the August 28 agreement, which gives Washington a direct interest in keeping a cooperative executive in place. Yet AP reported on August 29 that no agreement text had been released and core financing and implementation terms remained unclear. I treat it as a strong political signal, not a binding guarantee of survival.

The electoral route is too slow to make Machado the base case. Trump said on July 24 that Venezuela was not ready to vote and praised Rodríguez's performance. US-backed talks began in August, but the first agreement covered Supreme Court renewal and earthquake assets, not a presidential date (AP; EFE). On August 27, the National Assembly had only passed the court reform at first reading. The negotiators' published sequence puts a new court in November and a new electoral council in December (El País). An election, certification, and inauguration by December 31 would require the roadmap to skip its own prerequisites.

Machado remains the strongest electoral figure. An AtlasIntel poll fielded from July 30 through August 3 among 1,110 respondents, with a stated ±3-point margin of error, put her ahead of Rodríguez 57.4% to 17.7% in a hypothetical contest (reported results). Her ally Omar González returned on August 28, showing some political opening. But Machado is outside the formal talks and lacks command of ministries or security forces. Her path before year-end needs a sudden US reversal, direct installation, or regime collapse followed specifically by her accession.

Maduro's de facto restoration requires an even longer chain. A federal judge set his trial for June 1, 2027, with immunity and dismissal arguments scheduled for November 17, 2026. Even a favorable district-court ruling would not by itself return him to Caracas or restore command over the state. The government's deportation of Saab and its new oil relationship with Washington show that the ruling coalition is moving beyond him.

The main downside is an internal Chavista replacement. AP documented fractures over cooperation with Washington and the abandonment of Chávez-era policy. The oil announcement produced fresh criticism, but Jorge Rodríguez repeated the government's statement and Cabello redistributed it (El País, August 29). Cabello remains interior minister and therefore has a faster path to power than any opposition politician, but his recent public behavior still shows participation under Delcy rather than open defection.

Recent disorder data argue against making collapse a large bucket. My August 30 extract from ACLED's weekly updated monthly aggregates covered March 2025 through August 2026 and contained 514 political-violence events, 636 reported fatalities, and 2,483 demonstration events in Venezuela. These are event counts and reported fatality estimates, not participant totals, and ACLED warns against treating them as direct measures of territorial control (methodology). I read the data as evidence of high social pressure, but current reporting still shows a functioning central government and a coherent public chain of command.

I combined three lenses. The historical-survival model gets 40% weight and assigns Rodríguez 89%; the control-and-timetable model gets 35% and assigns 92%; the stress model gets 25% and assigns 78%, pricing in Cabello, legal limbo, oil backlash, disaster politics, assassination, and hidden military splits. The calculation is 0.40 × 0.89 + 0.35 × 0.92 + 0.25 × 0.78 = 0.873, which I report as 87% in prose. I allocate most of the remaining probability to another Chavista because, in the relevant Archigos forced-exit reference classes, insider or irregular successors account for roughly 50% to 69% of replacements.

What's non-obvious

Popularity is not the key state variable over this horizon. Machado can lead a fair election by a wide margin and still have only a 2% chance of exercising presidential powers by year-end, because the institutions needed to run that election are scheduled to be rebuilt near the deadline. The oil deal also cuts both ways: it raises the US cost of losing Rodríguez, while giving hardline Chavistas a vivid argument that she surrendered sovereignty. The lack of a published contract makes both effects hard to size.

The high-volume market named in the prompt is not the same event. Its roughly $95.9 million market resolves on the official officeholder, while the separate $374,000 de facto market matches this question more closely and showed Rodríguez at 91% on August 30. I checked it only after forming the independent estimate. I stay below it because palace politics are opaque, its deadline is twelve hours earlier, and its individual outcome contracts are thin.

Uncertainties

The largest gap is the oil agreement itself. No signed text was public by August 29, so the scale of US guarantees, Venezuelan approval requirements, and exit clauses cannot be verified. A published contract or the creation of the operating company would move the estimate toward Rodríguez.

Military loyalty is observed only through appointments, ceremonies, and public meetings. The August 4 National Guard pledge and August 25 security meeting favor Rodríguez, but they do not reveal private loyalties among Cabello, González López, intelligence chiefs, regional commanders, and colectivos. Unit-level dismissals, arrests, unexplained command changes, or Cabello's exclusion from security meetings would be the best early warning of an internal move.

The electoral roadmap is political, not binding law. A formal presidential date, a new electoral council appointed earlier than December, Machado's admission to the talks, or a US demand for transfer before December 31 would sharply raise the Machado or Other buckets. Continued court reform without an election decree would raise Rodríguez.

The quantitative prior is also imperfect. Archigos ends in 2015, REIGN ends in August 2021, and the tightest historical cells have only 25 to 54 cases. Those data support the direction and scale of the forecast, not the third decimal place.
