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

TL;DR

Delcy Rodríguez has an 86% chance of exercising Venezuela’s presidential powers on December 31, 2026. The main alternative is another Chavista at 8%; Machado and the residual category are about 3% each, while Maduro is under 1%. The short horizon, Rodríguez’s control of the state, and Washington’s revealed preference for delay outweigh her weak legal footing and the strains inside Chavismo.

Context

Nicolás Maduro has been in U.S. custody since his capture on January 3, while Rodríguez has exercised presidential powers since being sworn in on January 5 (AP). Article 234 of Venezuela’s constitution allows a vice president to replace a temporarily absent president for 90 days, extendable once by the National Assembly for another 90 days (WIPO). The first deadline expired without a publicly reported extension vote, yet Rodríguez remained in command (AP).

The forecast horizon is about 144 days. U.S.-backed government-opposition talks have only just begun, no presidential election date has been announced, and the process is focused first on restoring rights, rebuilding electoral institutions, and creating safe voting conditions (AP). The status quo therefore wins unless an internal coup, death or incapacity, a new U.S. policy, or a much faster political settlement intervenes.

Evidence

The historical backbone favors persistence. I built reference classes from Archigos 4.1, covering 3,409 effective-leader spells from 1875 through 2015; the Geddes-Wright-Frantz autocratic-regime data, covering 1946–2010; and Polity5, through 2020. The key calculation conditions on Rodríguez already having survived 216 days and asks whether comparable successors survived another 144 days, rather than using the much lower unconditional survival rate from their first day in office.

The cleanest foreign-removal samples are tiny, so I use 87%, not 93%, as the anchor. Among the seven target-class leaders who failed between days 216 and 360, four were removed through an internal power struggle, coup, or assassination; two left through a regular transition; and one was removed by foreign action (Archigos). That makes another regime insider the natural largest alternative. In the same dataset, none of 72 foreign-removed predecessors returned to power within 144 days, which puts Maduro’s historical restoration base rate near zero over this horizon (Archigos).

The current case mostly confirms that anchor. Rodríguez removed defense minister Vladimir Padrino López on March 18 and installed former intelligence chief Gustavo González López (Reuters). By late July she had sworn in another senior command, replaced the regional commanders originally appointed by Maduro, and ordered 110 generals and admirals into retirement (Infobae, Infobae). The reshuffle proves that her orders are obeyed. It does not prove personal loyalty: reporting on the new command also identifies officers connected to Diosdado Cabello’s network (Infobae).

Cabello remains the main internal risk. Early reporting described his control of police, security services, and armed civilian networks as the largest threat to Rodríguez, while Washington warned him against destabilizing her government (Reuters). Yet no open challenge followed. Rodríguez instead appointed Cabello’s brother to lead the state petrochemical company on July 7, which I read as coalition management rather than preparation for a purge or imminent showdown (Reuters). Public criticism inside Chavismo is real, but it has remained criticism rather than organized rebellion (AP).

Washington’s behavior is the strongest case-specific edge. A March court filing said the United States recognized Rodríguez as the sole head of state able to act for Venezuela (State Department filing). OFAC removed her from the sanctions list on April 1 (Federal Register). In July, the State Department determined that she qualified for sitting-head-of-state immunity in U.S. litigation (Miami Herald). On July 24, Trump said Venezuela was not ready for elections and praised the progress made under Rodríguez (Reuters). These are costly, repeated commitments to continuity, not mere diplomatic politeness.

Machado’s obstacle is timing and control, not popularity. The August talks are led by Jorge Rodríguez and Dinorah Figuera. The State Department said credible parties, open media, an honest electoral council, and secure polling places must come first, and that this would take time and patience; analysts interviewed by AP saw an immediate electoral calendar as unlikely after four failed dialogue processes between 2017 and 2024 (AP). Machado was left outside the talks with Washington’s approval (El País), and senior U.S. officials were frustrated by her June attempt to secure help for an immediate return (Reuters). To be president by December 31, she needs a safe return, a selection mechanism, Chavista and military compliance, and a completed swearing-in within four and a half months. No part of that chain is currently scheduled.

Maduro’s route is narrower. A federal judge set June 1, 2027 as his trial date, with initial dismissal motions due September 2 and arguments scheduled for November 17, 2026 (Reuters). Even a successful immunity motion would not by itself release him, return him to Venezuela, or reverse Rodríguez’s control of the state.

I therefore start at the 87% conditional-survival base rate and trim it slightly because this is a rare foreign-capture case, the coercive network is not exclusively Rodríguez’s, and the earthquakes and economic stress create discontinuous tail risks. I keep the reduction small because there is no election timetable, no public military split, no open Cabello challenge, and U.S. support deepened as recently as July. Within the failure branch, historical failure modes and current institutions put most probability on another Chavista, followed by a non-Machado transition or fragmented authority, Machado, and finally Maduro.

What's non-obvious

The legal deadline is less predictive than it looks. Rodríguez passed the initial 90-day limit and then the maximum 180-day period implied by Article 234 without losing the ministries, the armed forces, the legislature, or foreign recognition (Venezuelan constitution, AP). For this resolution, Maduro’s residual title is nearly irrelevant unless it turns back into actual command.

The client’s reference to the large Polymarket leader market also hides a semantic mismatch. That contract focuses on who officially holds the office, while a separate contract explicitly asks who exercises primary executive authority regardless of formal title (official-title market, de facto market). The second set of rules matches this question. The first does not. I made no adjustment from the large market.

The military purge is also a mixed signal. It raises confidence that Rodríguez can issue and enforce orders, but it does not show that she has replaced every rival network with personal loyalists. Several new commanders have ties to Cabello or older Chavista structures (Infobae). That is why another Chavista receives 8%, rather than a token tail.

Uncertainties

• The largest gap is private information about the loyalties of González López, regional commanders, Cabello’s security network, and the presidential guard. Public ceremonies and obeyed appointments show coordination, not what these actors would do during a real succession crisis.
• U.S. policy is unusually personalized. The forecast would move sharply if Trump or Rubio withdrew recognition, restored legal pressure on Rodríguez, or gave Machado explicit security backing. Public actions through July point the other way, but private conditions attached to U.S. support are unknown.
• The talks began only days before the cutoff (AP). A signed election date with a pre-December inauguration, Machado’s admission to the process, or agreement on another transitional president would override much of the current evidence.
• Conflict-event data count incidents and fatalities, not coup intent or command cohesion (ACLED codebook). Better evidence would include verified defections, unit movements around Caracas, arrests of senior commanders, and authenticated military communications. Absence of such reporting is weak evidence, not proof of unity.
