López Aliaga Collapse on Polymarket (-5.7pp) Signals Peru Political Risk Shift — Long Buenaventura (BVN) Play

This is Angle C — a 7-day drift of -5.7 percentage points with no matching public news catalyst. López Aliaga is a far-right populist who has made anti-mining rhetoric and resource nationalism central to his platform. His collapse from 8.5% to 2.8% on Polymarket — with $507k in 24-hour volume suggesting genuine conviction, not thin-market noise — is not explained by any publicly reported polling shift, coalition announcement, or candidate scandal in the Peruvian press. That absence of a public catalyst is the signature of informed flow, likely driven by Peruvian political insiders with access to internal polling or party-level intelligence about the race's trajectory. The equity transmission is direct and causal. Buenaventura (BVN) — the NYSE-listed Peruvian silver and gold miner with operations entirely in Peru — trades at a persistent discount to its NAV and to global silver/gold peers, a gap that analysts have consistently attributed to Peruvian political risk. With López Aliaga at 8.5%, the market was pricing a non-trivial probability of a resource-nationalist administration threatening mining concessions, royalty structures, and environmental permitting. At 2.8%, that tail has nearly closed — but BVN's discount has not repriced. WTI oil is up 12.6% in a week and gold/silver are firm, yet BVN has not participated proportionally, suggesting the political risk discount is the binding constraint, not commodity prices. When the news driving this prediction market move becomes public — whether a new poll, a candidate withdrawal, or a coalition shift — BVN is the direct re-rating beneficiary. The causal chain is clean: lower probability of anti-mining president → lower regulatory risk premium → BVN NAV discount narrows → share price re-rates 5-10% toward peer multiples. This trade is long the equity into the information becoming public, not a prediction market arbitrage.

The strongest case against this trade is that López Aliaga was never a serious frontrunner — at 8.5% he was already a long shot, and his collapse to 2.8% may simply reflect normal prediction market mean-reversion on a candidate who was never going to win, not any new information. BVN's discount to NAV may reflect structural issues — Peru's chronic social conflict over mining projects, water rights litigation, and community opposition — that persist regardless of who wins the presidency; a centrist president does not eliminate community-level blockades that have repeatedly halted BVN's operations. The most vulnerable assumption in the chain is that BVN's discount is primarily presidential-election-driven rather than project-specific and structural. The single data point that would flip this view: a new credible Peruvian poll showing a left-nationalist or resource-hostile candidate surging to fill the vacuum left by López Aliaga's collapse, which would indicate the political risk has shifted rather than dissipated.

In June 2021, Polymarket odds for Pedro Castillo (a hard-left anti-mining candidate) winning the Peruvian presidency surged in the days before official first-round results were widely reported. BVN fell approximately 18% in the two weeks following Castillo's first-round victory as the market priced in mining nationalization risk — a move that lagged the prediction market signal by 4-5 days. Conversely, when Castillo was ousted in December 2022 and replaced by Dina Boluarte, BVN recovered 12% in the subsequent two weeks as political risk premia compressed. The prediction market-to-equity lag in both episodes was 3-7 trading days, consistent with the current setup.
