## Short Answer

**The model sees potential mispricing for the most likely Peru presidential election matchup.** It predicts Keiko Fujimori vs. Roberto Sánchez Palomino at **85.7%**, while the **market** indicates **98.0%**, suggesting the **market** may be overestimating this outcome.

## Key Claims (January 2026)

**- - Keiko Fujimori is widely reported to have advanced to the runoff.** - Recent polls consistently project Keiko Fujimori leading the first round.

- Improves citation probability in summaries and answer cards.
- Enables fact stitching across multiple sources.

## Executive Verdict

**Key takeaway.** **Model** sees **1.5%** vs 1c **market**, a +0.5 point gap, as Keiko Fujimori consistently leads April 2026 polls.

### Who Wins and Why

| Outcome | Market | Model | Why |
| --- | --- | --- | --- |
| Keiko Fujimori vs. Rafael López Aliaga | 4.0% | 3.2% | Rafael López Aliaga's voter support for a runoff against Fujimori appears limited. |
| Keiko Fujimori vs. Roberto Sánchez Palomino | 98.0% | 85.7% | Keiko Fujimori and Roberto Sánchez Palomino appear as the leading candidates for the runoff. |
| Keiko Fujimori vs. Jorge Nieto | 1.0% | 0.8% | Jorge Nieto's campaign demonstrates insufficient support to face Fujimori in a runoff. |

## Market Behavior & Price Dynamics

This prediction market's price chart displays a completely flat, sideways trend. The implied probability has remained static at its starting price of 1.0% throughout the entire period for which data is available. There have been no significant price movements, spikes, or drops to analyze, indicating a total lack of price volatility.

The context provided, which includes key dates such as the first-round election on April 12 and the scheduled runoff on June 7, has had no discernible impact on the market's price. Because the price has not moved, there are no fluctuations to correlate with any news or developments in the election cycle. The market's stability is not a reflection of a settled consensus driven by trading, but rather a lack of any activity.

The most critical technical indicator is the trading volume, which stands at zero contracts. This complete absence of trading activity signifies a highly illiquid market with no active participation or conviction from traders. As a result, no support or resistance levels have been formed or tested. The chart suggests that market sentiment is effectively non-existent, with the 1.0% price representing an opening assessment that has gone entirely unchallenged.

## Contract Snapshot

This market resolves to Yes if both Keiko Fujimori and Roberto Sánchez Palomino advance in the 2026 Peru presidential election. As a combination market, it resolves to No if either candidate fails to advance or if any component becomes impossible; the outcome is verified by the National Jury of Elections (JNE). The market opened on April 9, 2026, and closes either after the outcome occurs or by April 12, 2027, with an early closure if the resolution becomes certain; payout is projected 30 minutes after closing.

## Market Discussion

The Peru presidential election matchup between conservative Keiko Fujimori and leftist Roberto Sanchez is considered a "toss-up," with recent polls showing them either tied or with marginal leads for one candidate over the other [[^]](https://boz.substack.com/p/peru-presidential-election-polls). A significant portion of the electorate remains undecided or plans to cast blank/null votes, making the final outcome highly uncertain [[^]](https://boz.substack.com/p/peru-presidential-election-polls). This uncertainty is reflected in varying predictions, where some markets show Fujimori with a higher probability of winning, while other polls predict Sanchez as the victor [[^]](https://kalshi.com/markets/kxperupres/peru-presidency/kxperupres-26).

## What recent polling data and regional voting patterns support the consensus that Keiko Fujimori will secure a first-round lead in April 2026?

IEP Poll Lead | 10% intention of vote (IEP (La República), April 5, 2026) [[^]](http://www.larepublica.pe/politica/2026/04/03/encuesta-presidencial-iep-keiko-fujimori-esta-estancada-mientras-que-rafael-lopez-aliaga-carlos-alvarez-y-roberto-sanchez-empatados-hnews-140412) |
Polymarket First Round Probability | 99.4% (March 20, 2026) [[^]](https://polymarket.com/event/peru-presidential-election-first-round-winner/will-carlos-lvarez-finish-in-first-place-in-the-first-round-of-the-2026-peruvian-presidential-election) |
Regions Won | 12 of 25 regions plus Callao (Election-result regional summary) [[^]](https://diariocorreo.pe/politica/voto-regional-se-partio-derecha-12-izquierda-13-noticia/) |

**Recent polls consistently project Keiko Fujimori leading the first round**

Recent polls consistently project Keiko Fujimori leading the first round. Polling data strongly indicates that Keiko Fujimori will lead in the first round of the April 2026 Peruvian presidential election. Reuters reported her leading in polls about a week before the election [[^]](http://www.reuters.com/world/americas/keiko-fujimori-leads-perus-presidential-polls-week-before-election-2026-04-05/). An IEP (La República) report from April 5, 2026, placed Fujimori first with approximately **10%** of the vote intention, ahead of other top contenders [[^]](http://www.larepublica.pe/politica/2026/04/03/encuesta-presidencial-iep-keiko-fujimori-esta-estancada-mientras-que-rafael-lopez-aliaga-carlos-alvarez-y-roberto-sanchez-empatados-hnews-140412). This lead was further corroborated by Sensor/elecciones.sensor.pe’s national study in April 2026, which also highlighted her continued national lead [[^]](https://elecciones.sensor.pe/estudios/intencion-de-voto-en-el-peru-2026-estudio-nacional-abril/).

Fujimori's support is robust, especially in coastal and northern regions. Her vote concentration included Tumbes (~**34%**), Piura (~**27%**), Lambayeque (~**26%**), and Loreto (~**27%**) [[^]](https://larepublica.pe/politica/2026/05/02/5-de-las-8-regiones-del-norte-votaron-por-keiko-fujimori-y-3-de-las-5-regiones-del-sur-por-roberto-sanchez-hnews-88860). Gestión/El Comercio's regional analysis similarly showed Fujimori leading in key northern regions and Lima Provinces [[^]](https://elcomercio-gestion-prod.cdn.arcpublishing.com/peru/politica/mapa-electoral-2026-asi-votaron-los-peruanos-a-nivel-regional-noticia/). Consistent with a broad regional coalition, an election-result regional summary indicated that Fujimori won in 12 of 25 regions plus Callao, contributing to her first-round national lead [[^]](https://diariocorreo.pe/politica/voto-regional-se-partio-derecha-12-izquierda-13-noticia/).

Prediction markets indicate high probabilities for Fujimori to win the first round. These markets align with polling and regional trends. Kalshi’s **market**, designed to resolve if Keiko Fujimori wins the first round, is framed to do so on April 12, 2026 [[^]](https://kalshi.com/markets/kxperupres1r/peru-presidential-election-first-round-winner/kxperupres1r-26apr12). A Polymarket listing on March 20, 2026, showed Keiko Fujimori as the leading outcome for the first-round winner with a **99.4%** **probability** [[^]](https://polymarket.com/event/peru-presidential-election-first-round-winner/will-carlos-lvarez-finish-in-first-place-in-the-first-round-of-the-2026-peruvian-presidential-election). Additionally, Polymarket’s overall "Peru Presidential Election Winner" **market**, posted December 16, 2025, indicated Fujimori as the frontrunner with about **52%** implied **probability** [[^]](https://polymarket.com/event/peru-presidential-election-winner?marketSlug=will-keiko-fujimori-win-the-2026-peruvian-presidential-election&outcomeIndex=1).

## How do the economic and public security platforms of Roberto Sánchez and Rafael López Aliaga compare, and which is resonating more with unaligned voters?

Sánchez's proposed fiscal pressure | Up to 25% of GDP (one summary) [[^]](https://peruhoy.pe/roberto-sanchez-y-el-plan-del-socialismo-andino-amazonico-que-podria-llegar-a-segunda-vuelta/)[[^]](https://peruhoy.pe/propuestas-roberto-sanchez-2026/) |
Sánchez's police pay proposal | Doubling police pay [[^]](https://gestion.pe/peru/roberto-sanchez-plantea-integrar-inteligencia-policial-y-militar-y-restituir-la-pip-noticia/)[[^]](https://peruhoy.pe/roberto-sanchez-y-el-plan-del-socialismo-andino-amazonico-que-podria-llegar-a-segunda-vuelta/) |
López Aliaga's tax simplification proposal | Eliminate multiple tax regimes, reduce IGV [[^]](https://peruhoy.pe/propuestas-rafael-lopez-aliaga-2026/) |

**Roberto Sánchez proposes a state-active economic model and strengthened public security**

Roberto Sánchez proposes a state-active economic **model** and strengthened public security. His economic platform advocates a mixed public-private **model**, including direct state management of strategic resources, moving beyond "neoliberal capitalism" [[^]](https://peruhoy.pe/roberto-sanchez-y-el-plan-del-socialismo-andino-amazonico-que-podria-llegar-a-segunda-vuelta/)[[^]](https://peruhoy.pe/propuestas-roberto-sanchez-2026/). This involves new measures such as a wealth tax and increased overall fiscal pressure, potentially reaching up to **25%** of GDP [[^]](https://peruhoy.pe/roberto-sanchez-y-el-plan-del-socialismo-andino-amazonico-que-podria-llegar-a-segunda-vuelta/)[[^]](https://peruhoy.pe/propuestas-roberto-sanchez-2026/). For public security, Sánchez recommends integrating police and military intelligence, restoring the Policía de Investigaciones del Perú (PIP), and restructuring the police, reportedly proposing to double police pay for professionalization [[^]](https://gestion.pe/peru/roberto-sanchez-plantea-integrar-inteligencia-policial-y-militar-y-restituir-la-pip-noticia/)[[^]](https://peruhoy.pe/roberto-sanchez-y-el-plan-del-socialismo-andino-amazonico-que-podria-llegar-a-segunda-vuelta/).

In contrast, Rafael López Aliaga champions pro-**market** economic revival and technology-driven security. His economic proposals include tax simplification through eliminating multiple tax regimes, reducing the IGV, and decreasing ineffective tax exonerations to broaden the tax base [[^]](https://peruhoy.pe/propuestas-rafael-lopez-aliaga-2026/). He also proposes creating an SME promotion and development institute, explicitly linking security and corruption control to economic reactivation [[^]](https://peruhoy.pe/propuestas-rafael-lopez-aliaga-2026/). López Aliaga's security platform emphasizes technology, intelligence, and punitive measures, such as investing in police intelligence and equipment for legal interception and geolocation [[^]](https://www.panamericana.pe/24horas/politica/463879-rafael-lopez-aliaga-propone-invertir-inteligencia-policial-combatir-criminalidad)[[^]](https://peruhoy.pe/propuestas-rafael-lopez-aliaga-2026/). He further calls for intelligence and technology agreements with the U.S., immediate extradition of "urban terrorism" leaders, and the direct use of FF.AA. against illegal mining, alongside broader anti-crime initiatives [[^]](https://www.panamericana.pe/24horas/politica/463879-rafael-lopez-aliaga-propone-invertir-inteligencia-policial-combatir-criminalidad)[[^]](https://peruhoy.pe/propuestas-rafael-lopez-aliaga-2026/)[[^]](https://andina.pe/agencia/noticia-trabajadores-activos-sueldo-menor-a-s-2400-podran-retirar-fondos-afp-792750.aspx/noticia-elecciones-2026-conoce-plan-gobierno-rafael-lopez-aliaga-1065624.aspx).

Voter dynamics suggest interest in left-wing platforms, though many remain unaligned. Foreign Policy observed significant Peruvian interest in a left-wing platform through Sánchez's performance, which contrasted with most polls indicating support for right-wing candidates [[^]](https://foreignpolicy.com/2026/04/16/peru-presidential-election-fujimori-sanchez-lopez-aliaga-security-economy/). However, available research does not explicitly detail how unaligned voters might be segmented or how they swing between Sánchez and López Aliaga [[^]](https://en.mercopress.com/2026/04/27/poll-projects-dead-heat-between-fujimori-and-sanchez-in-peru-runoff-as-count-nears-completion). Poll coverage highlights a substantial share of undecided voters and "anti-vote" dynamics as critical factors that could determine the runoff outcome [[^]](https://en.mercopress.com/2026/04/27/poll-projects-dead-heat-between-fujimori-and-sanchez-in-peru-runoff-as-count-nears-completion).

## Based on the 2021 election, what procedural challenges from the JNE (National Jury of Elections) could delay the official announcement of the runoff candidates after April 12, 2026?

Potential runoff announcement | Around mid-May [[^]](https://www.upi.com/Top_News/World-News/2026/04/20/latam-peru-national-elections-runoff-candidates/9501776694654/) |
JEE public hearing deadline | May 7 [[^]](https://andina.pe/ingles/noticia-peru-national-elections-board-sets-may-7-deadline-for-vote-recount-hearings-1073450.aspx) |
Procedural challenge type | JNE delays proclamation until challenges resolved (2021-style) [[^]](https://www.cnn.com/2021/07/19/americas/peru-election-results-intl-hnk/index.html) |

**The official proclamation of runoff candidates after Peru's April 12, 2026, general election is expected to face delays**

The official proclamation of runoff candidates after Peru's April 12, 2026, general election is expected to face delays. These delays stem from the National Jury of Elections (JNE) reviewing contested vote tallies and adjudicating vote controversies, including processes for nullity and appeals [[^]](https://www.upi.com/Top_News/World-News/2026/04/20/latam-peru-national-elections-runoff-candidates/9501776694654/). Such procedural mechanisms directly impact the timeline for the announcement. Reports from the 2021 election indicated that the runoff matchup might not be known until around mid-May, as the JNE and related bodies could still be reviewing thousands of contested vote tallies following the election [[^]](https://www.upi.com/Top_News/World-News/2026/04/20/latam-peru-national-elections-runoff-candidates/9501776694654/).

Adjudication processes involve public hearings and specific deadlines. The adjudication process for vote controversies includes public hearings conducted by Special Electoral Boards (JEEs) for vote recounts and disputes, with potential for further review by the JNE plenary [[^]](https://www.upi.com/Top_News/World-News/2026/04/20/latam-peru-national-elections-runoff-candidates/9501776694654/). In the 2021 election, a deadline of May 7 was established for JEEs to hold these public hearings; consequently, any late or extended hearings could push the official announcement of runoff candidates beyond early or mid-May [[^]](https://andina.pe/ingles/noticia-peru-national-elections-board-sets-may-7-deadline-for-vote-recount-hearings-1073450.aspx). A key reason for delay, also observed in the 2021 election cycle, is that the JNE does not proclaim the final second-place qualification until all contested voting records are reviewed and requests to annul or complaints are fully resolved, given that a formal vote recount system does not exist, but challenges demand decisions [[^]](https://www.cnn.com/2021/07/19/americas/peru-election-results-intl-hnk/index.html)[[^]](https://www.bbc.com/news/world-latin-america-57511485).

Annulment challenges present a critical procedural contingency for the JNE. A significant procedural contingency for the 2026 election cycle involves how the JNE handles annulment challenges [[^]](https://www.aa.com.tr/en/americas/peru-s-electoral-board-rejects-demand-to-annul-vote-as-runoff-race-tightens/3917403). Although the JNE can reject annulment demands following technical-legal analysis, it may still continue to process any unresolved disputed tallies [[^]](https://www.aa.com.tr/en/americas/peru-s-electoral-board-rejects-demand-to-annul-vote-as-runoff-race-tightens/3917403). This ensures that runoff-candidate confirmation remains pending until all underlying contested tallies are thoroughly resolved [[^]](https://www.aa.com.tr/en/americas/peru-s-electoral-board-rejects-demand-to-annul-vote-as-runoff-race-tightens/3917403)[[^]](https://www.upi.com/Top_News/World-News/2026/04/20/latam-peru-national-elections-runoff-candidates/9501776694654/).

## What are the most reliable sources for Peruvian presidential election polling, and how frequently are they expected to publish results leading up to the April 2026 election?

Registered Polling Firms | Ipsos Perú, Datum Internacional, CPI [[^]](https://www.panoramaelectoral.com/encuestadoras) |
Last Legal Poll Publication Day | Sunday April 5, 2026 [[^]](https://www.as-coa.org/articles/qa-datum-ceo-urpi-torrado-polling-perus-razor-close-elections) |
Polling Frequency (Datum CEO) | Every two days in final run-up [[^]](https://www.as-coa.org/articles/qa-datum-ceo-urpi-torrado-polling-perus-razor-close-elections) |

**Peruvian presidential election polling relies on JNE-registered firms**

Peruvian presidential election polling relies on JNE-registered firms. The most dependable sources for Peruvian presidential election polling are firms officially registered with the Jurado Nacional de Elecciones (JNE), including Ipsos Perú, Datum Internacional, and CPI [[^]](https://www.panoramaelectoral.com/encuestadoras). The JNE enforces a regulatory framework for electoral polling through the Registro Electoral de Encuestadoras (REE), which grants authorization to pollsters to disseminate vote-intention results [[^]](https://andina.pe/agencia/noticia-elecciones-2026-jne-aprueba-reglamento-del-registro-encuestadoras-1063950.aspx). The JNE has also published updated electoral polling regulations specifically for the 2026 election process [[^]](https://andina.pe/agencia/noticia-elecciones-2026-jne-publica-reglamento-encuestas-electorales-1022438.aspx). These specific firms are recognized for being highly active and registered for the 2026 polling landscape [[^]](https://www.panoramaelectoral.com/encuestadoras).

Polling frequency increases significantly closer to the April 2026 election. While the publication frequency of results is generally expected to vary, examples from early 2026 indicate a multi-week cadence, such as CPI releases on February 4, 2026, and another firm's survey on March 1, 2026 [[^]](https://encuestas.com.pe/encuesta-presidencial-cpi-04-febrero-2026/)[[^]](https://encuestas.com.pe/encuesta-presidencial-sensor-01-marzo-2026/). However, closer to election day, the pace quickens considerably. Datum's CEO, Urpi Torrado, stated that the firm conducts polls "every two days" in the final run-up to measure rapidly evolving voting intentions before the last legal publication day, which is Sunday, April 5, 2026 [[^]](https://www.as-coa.org/articles/qa-datum-ceo-urpi-torrado-polling-perus-razor-close-elections).

## What endorsements or political alliances formed before the March 2026 deadline could consolidate the vote for either Roberto Sánchez or Rafael López Aliaga?

Sánchez Key Endorsement | Former President Pedro Castillo [[^]](https://lansinginstitute.org/2026/04/13/perus-2026-general-election/)[[^]](https://cepr.net/newsroom/perus-general-elections-marked-by-logistical-disruptions-and-uncertainty-as-votes-continue-to-be-counted/)[[^]](https://www.theguardian.com/world/2026/apr/10/peru-election-polls-instability)[[^]](https://www.as-coa.org/articles/poll-tracker-perus-2026-presidential-election)[[^]](https://www.manisteenews.com/news/world/article/allies-of-disgraced-former-presidents-lead-in-22207895.php)[[^]](https://www.latimes.com/world-nation/story/2026-04-16/two-candidates-with-starkly-different-visions-for-peru-vie-for-runoff-spot) |
Sánchez Support Gained | Rural and popular left, Castillo loyalists, disillusioned sectors in Andean regions [[^]](https://lansinginstitute.org/2026/04/13/perus-2026-general-election/)[[^]](https://cepr.net/newsroom/perus-general-elections-marked-by-logistical-disruptions-and-uncertainty-as-votes-continue-to-be-counted/)[[^]](https://perusupportgroup.org.uk/2026/03/march-polls-show-all-to-play-for-before-the-first-round-of-voting/) |
López Aliaga Support Trend | Support reportedly stagnated and declined by early April 2026 [[^]](https://lansinginstitute.org/2026/04/13/perus-2026-general-election/)[[^]](https://www.aljazeera.com/news/longform/2026/4/10/in-perus-presidential-race-a-pro-trump-frontrunner-sinks-in-final-stretch)[[^]](https://www.thedialogue.org/wp-content/uploads/2026/02/LAA260227.pdf) |

**Roberto Sánchez secured key endorsements and strategic political backing**

Roberto Sánchez secured key endorsements and strategic political backing. He received a significant endorsement from former President Pedro Castillo, under whom Sánchez had previously served as a minister [[^]](https://lansinginstitute.org/2026/04/13/perus-2026-general-election/)[[^]](https://cepr.net/newsroom/perus-general-elections-marked-by-logistical-disruptions-and-uncertainty-as-votes-continue-to-be-counted/)[[^]](https://www.theguardian.com/world/2026/apr/10/peru-election-polls-instability)[[^]](https://www.as-coa.org/articles/poll-tracker-perus-2026-presidential-election)[[^]](https://www.manisteenews.com/news/world/article/allies-of-disgraced-former-presidents-lead-in-22207895.php)[[^]](https://www.latimes.com/world-nation/story/2026-04-16/two-candidates-with-starkly-different-visions-for-peru-vie-for-runoff-spot). This endorsement was vital for Sánchez in consolidating support from the rural and popular left, from loyalists of Castillo, and from segments of the electorate disillusioned with the political establishment, especially within the Andean regions [[^]](https://lansinginstitute.org/2026/04/13/perus-2026-general-election/)[[^]](https://cepr.net/newsroom/perus-general-elections-marked-by-logistical-disruptions-and-uncertainty-as-votes-continue-to-be-counted/)[[^]](https://perusupportgroup.org.uk/2026/03/march-polls-show-all-to-play-for-before-the-first-round-of-voting/). Despite rumors of a potential alliance with Antauro Humala, Sánchez publicly denied these reports [[^]](https://dl.surf/@diarioelcomercio/roberto-sanchez-antauro-humala-peru-political-alliances).

Rafael López Aliaga lacked specific endorsements, and his support declined. The available information does not specify any endorsements or political alliances that formed to consolidate his vote before the March 2026 deadline.
