Summary.
With just 11 days until Peru's April 12, 2026 first-round presidential election, Marisol Pérez Tello is polling below 1% in a crowded field of 35 candidates, while frontrunners López Aliaga and Fujimori hold 10-12% each. The market's 4% implied probability substantially overvalues her chances compared to my 0.8% estimate. While Peru has a history of electoral volatility (Pedro Castillo's 2021 surprise victory), those surges favored anti-establishment populist outsiders—not establishment figures like Pérez Tello, a former minister and congresswoman. For her to win, she would need to finish top-2 on April 12 (requiring a 10-20x polling surge in 11 days) AND win a June runoff—a compounded improbability that even Peru's 30-38% undecided voter rate cannot reasonably explain. The market appears to be overpricing tail risk by approximately 5x, likely extrapolating from historical volatility without accounting for the severe temporal constraints, unfavorable candidate profile, and mathematical improbability of her path to victory.
Reasoning.
Temporal Context: As of April 1, 2026, the first-round election is 11 days away (April 12). This is a critical timing factor—we are analyzing an essentially immediate electoral outcome, not a distant future event.
Current State Assessment:
- Marisol Pérez Tello is polling at <1% support with 11 days remaining
- She faces 34 other candidates in a highly fragmented field
- Frontrunners López Aliaga and Fujimori are at 10-12% each
- 30-38% of voters remain undecided, creating theoretical volatility potential
- Market odds imply 4% probability, a 4x premium over her polling
Path to Victory Analysis: For Pérez Tello to win, she would need to:
- First-round qualification: Finish in top 2 among 35 candidates (virtually certain to have a runoff given fragmentation)
- Runoff victory: Defeat the other top-2 finisher in June
With 11 days remaining and <1% polling, qualifying for the runoff would require:
- Capturing ~25-30% of the 34% undecided voters (to reach ~10% threshold for top-2)
- Doing so while 33 other candidates also compete for these voters
- Overcoming near-zero name recognition/momentum
Historical Precedent Evaluation: Peru has shown extreme electoral volatility (Pedro Castillo 2021 surged from obscurity), BUT:
- Castillo was a rural teacher union leader with populist, anti-establishment appeal
- Late surges have favored outsiders tapping into anti-Lima, anti-elite sentiment
- Pérez Tello is a former minister and congresswoman—quintessentially establishment
- Her center-progressive, Lima-based profile doesn't match the populist surge pattern
- No comparable case exists of an establishment candidate at <1% winning with 11 days left
Statistical Reality: With 11 days remaining and 35 candidates, the probability space is extremely constrained:
- Daily polling movement would need to be unprecedented (0.8-1% per day for 11 days)
- Media/debate cycles are largely complete this close to voting
- Early voting may have already begun
- Campaign infrastructure at <1% polling suggests minimal ground game
Market Premium Assessment: The 4% market odds vs ~0.5-1% polling-implied probability represents a significant premium. This likely reflects:
- Traders pricing in "black swan" tail risk from Peru's volatile history
- Uncertainty premium from the 30-38% undecided rate
- Possible confusion or wishful thinking by niche supporters
- Small market inefficiency (low liquidity on long-shot candidate)
My Estimate: 0.8% This is meaningfully below the 4% market odds but acknowledges:
- Non-zero tail risk given Peru's electoral history
- Extreme undecided rate creates theoretical pathways
- 11 days allows for one major event (scandal, debate moment, endorsement)
- But fundamentally, the math is nearly impossible: <1% → top 2 finish → runoff victory
The market appears to be overpricing tail risk by approximately 5x relative to the actual probability given timing constraints and candidate profile mismatch with historical surge patterns.
Key Factors.
Only 11 days remain until first-round voting—extremely limited time for momentum building
Polling at <1% requires 10-20x surge just to qualify for runoff (top 2 of 35 candidates)
Establishment profile doesn't match Peru's historical pattern of populist outsider surges
30-38% undecided voters create theoretical volatility, but these must break heavily toward Pérez Tello
Two-stage victory requirement (first-round qualification AND runoff win) compounds improbability
Frontrunners at 10-12% have significant infrastructure and media advantages
No evidence of campaign momentum, viral movements, or major endorsements in final weeks
Scenarios.
Base Case: Early elimination
97%Pérez Tello finishes outside the top 2 in the April 12 first round, receiving between 0.5-2% of the vote. Undecided voters break primarily toward frontrunners and other more prominent candidates. The election proceeds to a runoff between López Aliaga and Fujimori (or another top-tier candidate), with Pérez Tello becoming irrelevant to the final outcome.
Trigger: Final polling in the April 8-11 window continues to show Pérez Tello at <2%. No major scandals affect frontrunners. Undecided voters consolidate around 4-6 leading candidates rather than fragmenting across all 35.
Tail Risk: Shock event creates opening
3%A major scandal, disqualification, health crisis, or other shock eliminates or severely damages 1-2 frontrunners in the final week. Media attention concentrates on Pérez Tello as a 'safe' establishment alternative. She surges to 8-12% and qualifies for the runoff, then wins by consolidating the anti-Fujimori vote or broader establishment support in June.
Trigger: Major corruption revelation or legal disqualification of López Aliaga or Fujimori between April 2-10. Emergency polling shows Pérez Tello surging to 8%+ as beneficiary. Strong debate performance or major endorsement (e.g., from eliminated centrist candidates) accelerates momentum.
Black Swan: Polling catastrophically wrong
1%All polls have systematically missed Pérez Tello's support, possibly due to 'shy voter' effects, cell-phone-only voters, or last-minute shifts invisible to pollsters. She performs dramatically better than expected on April 12, finishing in the top 2 and proceeding to win the runoff. This would represent one of history's greatest polling failures.
Trigger: Exit polls on April 12 show Pérez Tello at 10%+ versus <1% in pre-election surveys. Post-election analysis reveals systematic sampling bias or a 48-hour viral social media movement that polls couldn't capture. This scenario has no clear advance warning—it would only be visible in the actual vote count.
Risks.
Polls could be systematically wrong due to methodology failures with undecided voters or cell-phone-only demographics
A major scandal or disqualification of frontrunners in the final week could reshape the race entirely
Social media-driven movements can materialize rapidly in Latin American elections, potentially invisible to traditional polling
The 30-38% undecided rate is unusually high—if these voters break in coordinated fashion (e.g., via viral campaign), outcomes could shift dramatically
Early voting data and actual turnout patterns may differ substantially from polling samples
Peru's extreme political fragmentation and anti-establishment sentiment could manifest in unexpected ways
Limited information on Pérez Tello's campaign spending, ground game, or media strategy—she may have resources not reflected in polling
Market participants may have information not captured in public polling (private polls, ground intelligence, betting syndicates)
Edge Assessment.
EDGE IDENTIFIED: Market appears to be overpricing this outcome by approximately 5x.
Market odds: 4.0% (implied probability) My estimate: 0.8% Expected value calculation: At 4% market odds, fair payout is 25:1. At 0.8% true probability, fair payout should be 125:1.
Assessment: The market is significantly overvaluing Pérez Tello's chances. The 4% implied probability appears to reflect:
- Tail risk over-pricing: Traders extrapolating from Pedro Castillo 2021 without accounting for candidate profile differences
- Temporal miscalibration: Not fully adjusting for the extremely short 11-day timeline
- Undecided voter illusion: Overestimating the probability that 30%+ undecided voters would consolidate behind a <1% candidate
- Small market inefficiency: Possible low liquidity allowing wishful thinking or uninformed betting to skew odds
Recommended position: The mathematically correct position is to FADE this market (bet NO or sell YES positions). The 4% odds offer poor value given the <1% realistic probability. However, the payout structure matters—if this is a binary market where NO pays only 1.04:1, transaction costs may eliminate practical edge. The edge is clearest in markets allowing short positions or proportional payouts.
Caveats:
- In highly volatile political environments, tail risk premiums have some justification
- With only 11 days until resolution, new information could emerge rapidly
- If you have strong conviction that polls are systematically wrong, this assessment would change
- Peru's political unpredictability means even 0.8% probabilities should be taken seriously
Bottom line: Market is overpaying for a compelling narrative (Peru's volatility history) while underweighting the mathematical and temporal constraints. This represents a modest but real edge opportunity for disciplined bettors.
What Would Change Our Mind.
Major scandal or legal disqualification of both López Aliaga and Fujimori between April 2-10 that creates a sudden frontrunner vacuum
Emergency polling between April 5-10 showing Pérez Tello surging to 8%+ support, indicating a momentum shift invisible to March polls
Credible evidence of systematic polling failure (e.g., leaked internal campaign polls, massive social media movement metrics, or reports of ground game strength not captured in surveys)
High-profile endorsement from eliminated candidates or major political figures that consolidates centrist/establishment voters behind Pérez Tello
Exit polls on April 12 showing Pérez Tello dramatically outperforming pre-election surveys by 5-10 percentage points

Fed Interest Rate Increase of 25+ bps After April 2026 Meeting
Based on analysis as of March 20, 2026, the probability of a 25+ bps Fed rate hike at the April 28-29 meeting is estimated at 1%, precisely matching the CME FedWatch market-implied probability. This represents near-universal consensus that a hike will NOT occur. The overwhelming evidence includes: (1) the March 17-18 FOMC dot plot showing zero of 12 participants projecting any rate increases in 2026, with median forecast indicating one 25 bps CUT by year-end; (2) the only dissent at the March meeting was Governor Miran voting for a CUT, not a hike; (3) Chair Powell's messaging emphasizing patience and viewing current 3.50%-3.75% rates as "sufficiently restrictive"; (4) inflation attributed to temporary supply shocks (tariffs, Middle East energy crisis) rather than demand overheating requiring tighter policy; and (5) the Fed having just completed a cutting cycle in late 2025, with historical precedent showing such pauses lead to holds or eventual cuts, not renewed tightening. Even the most hawkish mainstream analysts expect no hikes until 2027 at earliest. With only 39 days until the April meeting, there is insufficient time for the catastrophic inflation data that would be required to force a complete Fed policy reversal. The market is correctly priced with no identifiable edge.
Courts consider Amazon a monopoly?
The market assigns a 58.5% probability that a U.S. District Court will find Amazon illegally maintained a monopoly, while our analysis estimates 52%—a modest 6.5 percentage point discrepancy. The FTC's case has survived two dismissal attempts and benefits from a lengthy discovery period and favorable precedent (DOJ v. Google Search), but three factors suggest the market may be overconfident in a government victory: (1) Settlement risk is substantial—historical antitrust cases of this magnitude settle 40-60% of the time, and any settlement would resolve NO since it avoids a court monopoly finding; (2) FTC Chair Andrew Ferguson's less aggressive stance than predecessor Lina Khan may increase settlement pressure despite maintaining the case for 18+ months; (3) High evidentiary burdens at trial—surviving pleading-stage motions does not translate linearly to proving complex market definition and anticompetitive effects claims. Our scenario modeling assigns 35% probability to government trial victory, 33% to settlement (resolves NO), and 32% to Amazon trial victory. Confidence is low (0.45) due to significant information asymmetry: discovery evidence quality, settlement negotiation status, and Judge Chun's substantive views remain opaque to public markets. The 4-year timeline to 2030 resolution creates substantial intervening event risk.
Courts consider Amazon a monopoly?
The market prices FTC victory at 65%, while my analysis estimates 58% probability that Judge Chun will rule Amazon illegally maintained a monopoly. The FTC has strong procedural momentum: Judge Chun denied Amazon's motion to dismiss in September 2024 (a significant positive signal as most antitrust cases surviving this hurdle have elevated government success rates), and Amazon's $2.5 billion Prime settlement before the same judge in September 2025 suggests compelling internal discovery evidence and judicial receptiveness to government arguments about Amazon's practices. However, the market appears to overly discount critical risks. Market definition remains contested as evidenced by the March 7, 2026 economics hearing—if Amazon successfully argues the relevant market includes all retail (Walmart, Target, brick-and-mortar), its market share falls below monopoly thresholds and the case collapses regardless of conduct evidence. Historical base rates show ~50-60% government win rates in monopoly maintenance trials. While procedural strength justifies upward adjustment, the 65% market price exceeds what the evidence supports given ongoing market definition disputes, discovery still in progress through April 2026, and inherent unpredictability of bench trial outcomes. The 7-percentage-point gap represents a modest edge but meaningful mispricing.
