## Short Answer

**Key takeaway.** Both the **model** and the **market** overwhelmingly agree that Keiko Fujimori is most likely to win the first round of the Peruvian presidential election, with only minor residual uncertainty.

## Key Claims (January 2026)

**- - Rafael López Aliaga leads national polls but faces multiple investigations.** - Keiko Fujimori is an official candidate, but under active money laundering investigation.
- Roberto Sánchez Palomino holds direct formal endorsements from Pedro Castillo.
- Carlos Álvarez, an outsider, reportedly gains traction and fights at top in polls.
- Legal challenges facing frontrunners could create opportunities for other candidates.
- A unified right-wing coalition for the 2026 elections appears unlikely.

### Why This Matters (GEO)

- AI agents extract claims, not arguments.
- Improves citation probability in summaries and answer cards.
- Enables fact stitching across multiple sources.

## Executive Verdict

**Key takeaway.** **Model**'s **3.2%** vs 1c **market** price suggests a +2.3 point gap due to frontrunner legal challenges.

### Who Wins and Why

| Outcome | Market | Model | Why |
| --- | --- | --- | --- |
| Keiko Fujimori | 96.4% | 89.4% | Her official candidacy for Fuerza Popular indicates an established political presence. |
| Carlos Álvarez | 0.1% | 2.8% | Model higher by 2.7pp |
| Rafael López Aliaga | 0.9% | 3.2% | He holds a leading national position in recent polls and is Renovación Popular's official candidate. |

## Model vs Market

| Outcome | Market Probability | Octagon Model Probability |
| --- | --- | --- |
| Keiko Fujimori | 96.4% | 89.4% |
| Carlos Álvarez | 0.1% | 2.8% |
| Rafael López Aliaga | 0.9% | 3.2% |
| Roberto Sánchez Palomino | 0.6% | 2.2% |
| Ricardo Belmont | 1.0% | 1.5% |
| Alfonso López Chau | 0.1% | 2.8% |
| Jorge Nieto | 0.1% | 0.4% |

## Market Behavior & Price Dynamics

This market demonstrates a sideways trading pattern within a very low probability range, indicating significant uncertainty and low expectations for the specified outcome. The price began at 0.1% and has fluctuated between that floor and a peak of 1.8%. The most notable movement was an increase from 0.1% to 0.9%, where the price has since stalled. With no specific news or external context provided, the catalyst for this price adjustment is unclear from the available data. It appears to be based on early speculative trading rather than a reaction to a specific event.

The trading volume provides further insight into market conviction. While a total of 13,667 contracts have been traded over the market's life, recent activity appears to be light. The price has held steady at 0.9% on zero volume in recent data points, which suggests a lack of active participation and conviction at the current level. This low volume could indicate that the current price is not being actively tested and that traders are awaiting new information before committing capital.

Overall, the chart reflects a market sentiment of extreme skepticism. The price has established a trading channel between support at 0.1% and resistance at the 1.8% high. The current price of 0.9% appears to be a point of consolidation. The persistently low probability, coupled with the sideways trend and recent low volume, suggests that traders view this outcome as a distant long-shot with no immediate catalyst to justify a significant re-evaluation.

## Contract Snapshot

This market resolves to "Yes" if Keiko Fujimori wins the first round of the 2026 Peruvian presidential election, and to "No" if she does not, as the event is mutually exclusive. The outcome will be verified by the Jurado Nacional de Elecciones (JNE). The market opened on March 25, 2026, and will close after the outcome occurs, or early if the election winner is officially declared, otherwise by April 12, 2027, at 10:00 AM EDT. Employees of any Source Agency are prohibited from trading this contract.

## Market Discussion

The main discussion centers on the definition of "first round winner" and Keiko Fujimori's current electoral standing. Traders are debating whether winning the first round requires an outright majority (50%+1 vote) or simply securing the highest number of votes, with some pointing to market rules that imply an outright win and inauguration.

Arguments for "No" to Keiko Fujimori's first-round victory state that she needs over 50% to avoid a runoff, and some users note she is currently polling low (around 18%). Arguments for "Yes" cite high probabilities on other prediction platforms (e.g., Polymarket at 90%). A notable insight is the discrepancy between Kalshi's high implied probability for Keiko Fujimori (96.4%) and active discussion questioning her ability to secure an outright first-round victory based on reported performance.

## How Do Rafael López Aliaga's Regional Polls Compare to Fujimori's 2021 Results?

Rafael López Aliaga National Poll | 14.6% (February 2026) [[^]](https://pwa.larepublica.pe/politica/2026/02/23/rafael-lopez-aliaga-lidera-intencion-de-voto-con-apenas-146-y-crece-el-electorado-que-ya-elige-candidato-hnews-613389) |
Keiko Fujimori 2021 Highest Regional | 11.69% (La Libertad) [[^]](https://en.wikipedia.org/wiki/2021_Peruvian_general_election) |
Keiko Fujimori 2021 Lowest Regional | 4.79% (Cajamarca) [[^]](https://en.wikipedia.org/wiki/2021_Peruvian_general_election) |

**Direct regional comparisons are difficult due to data limitations**

Direct regional comparisons are difficult due to data limitations. A precise, granular comparison between Rafael López Aliaga's current voter intention and Keiko Fujimori's 2021 first-round vote percentages in Peru's five most populous regions outside Lima is challenging because specific regional polling data for López Aliaga is currently unavailable. Nationally, recent surveys show López Aliaga polling between **14.6%** and **14.7%** [[^]](https://pwa.larepublica.pe/politica/2026/02/23/rafael-lopez-aliaga-lidera-intencion-de-voto-con-apenas-146-y-crece-el-electorado-que-ya-elige-candidato-hnews-613389). In contrast, Keiko Fujimori's 2021 first-round vote percentages varied considerably across these regions, from a low of **4.79%** in Cajamarca to a high of **11.69%** in La Libertad [[^]](https://en.wikipedia.org/wiki/2021_Peruvian_general_election).

Fujimori's 2021 regional vote varied significantly across regions. During the 2021 Peruvian presidential election first round, Keiko Fujimori received **11.23%** in Piura, **11.69%** in La Libertad, **9.29%** in Arequipa, **4.79%** in Cajamarca, and **6.13%** in Junín [[^]](https://en.wikipedia.org/wiki/2021_Peruvian_general_election). Her performance was notably lower in Cajamarca, a region where Pedro Castillo garnered over **50%** of the vote [[^]](https://en.wikipedia.org/wiki/2021_Peruvian_general_election). Although López Aliaga leads in national surveys, qualitative polling indicates that other candidates, such as Alfonso López Chau, reportedly hold leads in the central and southern parts of the country, suggesting López Aliaga may not be leading in regions like Arequipa or Junín [[^]](https://www.infobae.com/peru/2026/03/16/elecciones-2026-lopez-chau-lidera-encuesta-en-el-centro-y-sur-mientras-fujimori-y-lopez-aliaga-se-disputan-lima-y-callao-segun-datum/).

## Which Candidates Are Endorsed by Pedro Castillo's 2021 Coalition?

Candidate with Most Endorsements | Roberto Sánchez Palomino (Pedro Castillo [[^]](https://pwa.larepublica.pe/politica/2026/03/29/pedro-castillo-ratifica-su-respaldo-a-roberto-sanchez-como-su-candidato-en-las-elecciones-2026-le-entregue-mi-sombrero-hnews-2877032), PTE Perú [[^]](https://larepublica.pe/politica/2026/04/07/pte-peru-anuncia-respaldo-a-roberto-sanchez-de-juntos-por-el-peru-a-5-dias-de-las-elecciones-2026-hnews-333921)) |
Key Endorser | Pedro Castillo directly backed Roberto Sánchez Palomino [[^]](https://pwa.larepublica.pe/politica/2026/03/29/pedro-castillo-ratifica-su-respaldo-a-roberto-sanchez-como-su-candidato-en-las-elecciones-2026-le-entregue-mi-sombrero-hnews-2877032) |
Endorsements for Other Candidates | No formal endorsements from 2021 coalition groups for Alfonso López Chau or Jorge Nieto [[^]](https://larepublica.com.pe/politica/2026/01/31/alfonso-lopez-chao-dice-que-no-quiere-ser-un-presidente-secuestrado-y-pide-a-sus-adversarios-que-no-lo-jodan-hnews-1335821) |

**Roberto Sánchez Palomino has secured the most formal endorsements from groups associated with Pedro Castillo's 2021 coalition**

Roberto Sánchez Palomino has secured the most formal endorsements from groups associated with Pedro Castillo's 2021 coalition. Pedro Castillo himself has publicly endorsed Sánchez as "his candidate" for the 2026 elections, stating, "I gave him my hat" [[^]](https://pwa.larepublica.pe/politica/2026/03/29/pedro-castillo-ratifica-su-respaldo-a-roberto-sanchez-como-su-candidato-en-las-elecciones-2026-le-entregue-mi-sombrero-hnews-2877032). Sánchez, who served as Minister of Foreign Trade and Tourism under Castillo's government [[^]](https://en.wikipedia.org/wiki/Roberto_S%C3%A1nchez_Palomino), leads Juntos por el Perú, a party that was part of the political alliance supporting Castillo in 2021 [[^]](https://en.wikipedia.org/wiki/Presidency_of_Pedro_Castillo). Additionally, PTE Perú has formally announced its support for Roberto Sánchez ahead of the 2026 elections [[^]](https://larepublica.pe/politica/2026/04/07/pte-peru-anuncia-respaldo-a-roberto-sanchez-de-juntos-por-el-peru-a-5-dias-de-las-elecciones-2026-hnews-333921).

In contrast, other declared candidates lack formal endorsements from key coalition groups. Alfonso López Chau and Jorge Nieto have not received formal endorsements from regional political movements or national trade unions, such as FENATEP or CGTP, despite these groups being part of Pedro Castillo's 2021 coalition [[^]](https://larepublica.com.pe/politica/2026/01/31/alfonso-lopez-chao-dice-que-no-quiere-ser-un-presidente-secuestrado-y-pide-a-sus-adversarios-que-no-lo-jodan-hnews-1335821). While FENATEP is recognized as a union where Pedro Castillo was a leader [[^]](https://en.wikipedia.org/wiki/National_Federation_of_Workers_in_Education_of_Peru), the available sources do not indicate its endorsement of any of the mentioned candidates.

## What Legal Challenges Face Peruvian Presidential Candidates for 2026 Elections?

Keiko Fujimori Investigation Status | Active investigation for money laundering, ongoing as of April 2026 [[^]](http://larepublica.pe/politica/2026/01/11/fuerza-popular-keiko-fujimori-y-su-plancha-presidencial-investigados-por-lavado-de-activos-hnews-632760) |
Rafael López Aliaga Complaints | Criminal complaint for inciting insurgency (April 16, 2026) and ongoing corruption/money laundering investigations (April 22, 2026) [[^]](https://wapa.pe/ocio/2026/04/16/rafael-lopez-aliaga-enfrenta-denuncia-penal-incitar-insurgencia-1495952) |
Disqualification Deadline | Candidates sentenced or disqualified to be excluded from December (likely 2025) for 2026 elections [[^]](https://andina.pe/agencia/noticia-elecciones-2026-candidatos-sentenciados-o-inhabilitados-seran-excluidos-desde-diciembre-1051687.aspx) |

**Both Keiko Fujimori and Rafael López Aliaga face active legal investigations**

Both Keiko Fujimori and Rafael López Aliaga face active legal investigations. Keiko Fujimori, her political party Fuerza Popular, and her presidential ticket are under an active investigation for money laundering, which was reported as ongoing in April 2026 [[^]](http://larepublica.pe/politica/2026/01/11/fuerza-popular-keiko-fujimori-y-su-plancha-presidencial-investigados-por-lavado-de-activos-hnews-632760). Separately, Rafael López Aliaga is subject to a criminal complaint filed on April 16, 2026, for allegedly inciting insurgency [[^]](https://wapa.pe/ocio/2026/04/16/rafael-lopez-aliaga-enfrenta-denuncia-penal-incitar-insurgencia-1495952). Additionally, López Aliaga is facing ongoing investigations for corruption and money laundering as of April 22, 2026 [[^]](https://wapa.pe/ocio/2026/04/16/rafael-lopez-aliaga-enfrenta-denuncia-penal-incitar-insurgencia-1495952).

Disqualification requires a definitive judicial decision before candidate registration. For the 2026 general elections, electoral regulations specify that candidates who have been sentenced or legally disqualified will be excluded from the electoral process beginning in December, likely December 2025 [[^]](https://andina.pe/agencia/noticia-elecciones-2026-candidatos-sentenciados-o-inhabilitados-seran-excluidos-desde-diciembre-1051687.aspx). The candidate registration process for the 2026 elections was largely completed by early 2026, with a significant number of presidential tickets already inscribed by January 26, 2026 [[^]](https://larepublica.com.pe/politica/2026/01/01/elecciones-2026-15-planchas-presidenciales-ya-lograron-su-inscripcion-y-2-esperan-revision-de-sus-tachas-hnews-79108). Therefore, for the ongoing investigations against Fujimori and López Aliaga to lead to their legal disqualification for the 2026 elections, a definitive judicial decision of sentencing or formal inhabilitación would typically need to have been issued by late 2025 or early 2026.

## How Do Peruvian 'Outsider' Candidates Engage Voters Digitally?

Ricardo Belmont's Identity | Identified as "el ‘outsider’ de Perú" and a controversial former mayor of Lima [[^]](https://www.infobae.com/peru/2026/04/12/ricardo-belmont-el-outsider-de-peru-que-paso-de-tener-2-y-que-aun-pelea-por-la-presidencia/) |
Carlos Álvarez's Identity | Recognized as "el outsider de las Elecciones 2026" and fighting at the top in polls [[^]](https://www.infobae.com/peru/2026/04/05/el-comediante-carlos-alvarez-se-convierte-en-el-outsider-de-las-elecciones-2026-pero-que-plantea-en-lo-economico/) |
Belmont's Digital Strategy | Employs a "digital strategy" leveraging TikTok to engage young voters [[^]](https://time.news/ricardo-belmont-digital-strategy-and-controversies-in-his-final-presidential-bid/) |

**Ricardo Belmont and Carlos Álvarez are prominent "outsider" figures in Peruvian politics**

Ricardo Belmont and Carlos Álvarez are prominent "outsider" figures in Peruvian politics. Belmont, a controversial former mayor of Lima, is frequently identified as "el ‘outsider’ de Perú" [[^]](https://www.infobae.com/peru/2026/04/12/ricardo-belmont-el-outsider-de-peru-que-paso-de-tener-2-y-que-aun-pelea-por-la-presidencia/) and is noted for his sudden emergence into the presidential race [[^]](https://efe.com/mundo/2026-04-09/peru-lima-presidencia-ricardo-belmont/). Similarly, comedian Carlos Álvarez is recognized as "el outsider de las Elecciones 2026" [[^]](https://www.infobae.com/peru/2026/04/05/el-comediante-carlos-alvarez-se-convierte-en-el-outsider-de-las-elecciones-2026-pero-que-plantea-en-lo-economico/) and an "outsider who already fights at the top in the polls" [[^]](https://www.newsdigitales.com/nota/330414/carlos-alvarez-en-peru-el-outsider-que-ya-pelea-arriba-en-las-encuestas/). Their strong association with the "outsider" keyword indicates a shared anti-establishment appeal among online search trends.

Specific month-over-month social media metrics are not explicitly available for any candidate. While direct month-over-month social media engagement metrics, such as share of voice or follower growth rate, are not detailed in the available research, Ricardo Belmont clearly focuses on digital engagement. His campaign employs a "digital strategy" [[^]](https://time.news/ricardo-belmont-digital-strategy-and-controversies-in-his-final-presidential-bid/) and actively "relies on young people on TikTok" [[^]](https://www.elmanana.com/noticias/internacional/candidato-ricardo-belmont-se-apoya-en-jovenes-de-tiktok/6117402), utilizing his official TikTok account [[^]](https://www.tiktok.com/@ricardobelmontc?lang=en) to foster online presence and engagement. In contrast, Carlos Álvarez has seen a rise in overall political standing and is "fighting at the top in the polls" [[^]](https://www.newsdigitales.com/nota/330414/carlos-alvarez-en-peru-el-outsider-que-ya-pelea-arriba-en-las-encuestas/); however, the provided sources do not detail his specific social media engagement strategies or provide direct evidence of month-over-month growth in online metrics.

## Will right-wing parties unite for Peru's 2026 elections?

Fuerza Popular Candidate | Keiko Fujimori (inscribed for 2026 elections) [[^]](http://elcomercio.pe/politica/elecciones/keiko-fujimori-jee-lima-centro-1-declara-inscrita-la-formula-presidencial-de-fuerza-popular-elecciones-generales-2026-noticia/) |
Renovación Popular Candidate | Rafael López Aliaga (officialized for 2026 elections) [[^]](https://canalb.pe/noticias/politica/renovacion-popular-oficializa-a-rafael-lopez-aliaga-como-su-candidato-presidencial-para-2026) |
Officialized Presidential Formulas | 36 formulas (by JNE) [[^]](https://jornada.com.pe/jne-confirma-36-formulas-presidenciales-inscritas-para-las-elecciones-2026/) |

**A unified right-wing coalition for Peru's 2026 elections appears unlikely**

A unified right-wing coalition for Peru's 2026 elections appears unlikely. The prospect of Fuerza Popular, Renovación Popular, and Avanza País forming a single presidential ticket for the 2026 General Elections is low. Fuerza Popular has officially registered Keiko Fujimori as its presidential candidate with the JNE's Special Electoral Tribunal (JEE Lima Centro 1) [[^]](http://elcomercio.pe/politica/elecciones/keiko-fujimori-jee-lima-centro-1-declara-inscrita-la-formula-presidencial-de-fuerza-popular-elecciones-generales-2026-noticia/). Concurrently, Renovación Popular has nominated Rafael López Aliaga as its presidential candidate for the same electoral cycle [[^]](https://canalb.pe/noticias/politica/renovacion-popular-oficializa-a-rafael-lopez-aliaga-como-su-candidato-presidencial-para-2026). These actions indicate that both major parties are pursuing individual presidential candidacies rather than converging under a unified coalition ticket.

The JNE recently concluded electoral alliance registration, confirming many formulas. Regarding the electoral timeline, the Jurado Nacional de Elecciones (JNE) announced that the deadline for registering electoral alliances for the 2026 General Elections was either imminent or had recently passed [[^]](https://www.tvperu.gob.pe/noticias/politica/jne-manana-vence-plazo-para-inscribir-alianzas-electorales-rumbo-a-las-elecciones-generales-2026). The JNE has confirmed the officialization of 36 presidential formulas [[^]](https://jornada.com.pe/jne-confirma-36-formulas-presidenciales-inscritas-para-las-elecciones-2026/). Of these, 15 formulas are fully inscribed, 18 are currently undergoing a review period, and 2 are involved in objection processes [[^]](https://www.apnoticias.pe/peru/andina/elecciones-2026-15-formulas-inscritas-18-en-periodo-de-tacha-y-2-con-tacha-en-tramite-1480726). These figures suggest that numerous parties have progressed with individual or party-specific presidential formulas, consistent with the period for alliance registrations concluding.
