Index: https://market-claims.com/briefs ## Will Nicolas Maduro still lead Venezuela at the end of 2026? Polymarket resolves on whoever officially holds the Venezuelan head-of-state position on 31 December 2026. The evidence gathered here is the most directionally mixed of any brief in the library: reporting on internal and external pressure on Maduro's position alongside reporting on its durability. Read it as a map of what is being reported on both sides, not as a probability. - Page: https://market-claims.com/briefs/venezuela-maduro-leadership-2026 - Markdown: https://market-claims.com/briefs/venezuela-maduro-leadership-2026.md - Category: politics - Research dated: 24 September 2026 (older snapshot) ## Will Maria Corina Machado enter Venezuela before 30 September? A short-dated market on whether the Venezuelan opposition leader physically enters Venezuelan territory before 30 September. Everything retrieved here is statement of intent rather than confirmed movement: Machado saying she is preparing to return, framing that return as a contribution to a political process, and citing the release of political prisoners and the social and economic situation as her reasons, with Ivan Duque expressing a supporting view. Stated intent is weak evidence for a deadline market, and no claim establishes a date, a route, or any confirmation of entry. - Page: https://market-claims.com/briefs/venezuela-machado-return - Markdown: https://market-claims.com/briefs/venezuela-machado-return.md - Category: politics - Research dated: 22 September 2026 (older snapshot) ## Brazil 2026 presidential election: what September polling says about a Lula win Polymarket asks whether Luiz Inacio Lula da Silva wins the 2026 Brazilian presidential election on 4 October, second round included. The September Quaest polling collected here runs against the proposition: it puts Flavio Bolsonaro on 42% against Lula in a simulated runoff, a one-point lead inside a two-point margin of error, and records rejection rates of 56% for Bolsonaro and 55% for Lula. Separately, 50% disapprove of the Lula government against 44% who approve. This is one pollster's September readings, not a forecast, and it says nothing about who will win. - Page: https://market-claims.com/briefs/brazil-presidential-2026-lula - Markdown: https://market-claims.com/briefs/brazil-presidential-2026-lula.md - Category: politics - Research dated: 22 September 2026 (older snapshot) ## Tesla and SpaceX merger officially announced by June 30, 2027? 30 dated claims from 14 publishers are collected below, each with its source. 14 point toward YES and 1 against it; the rest are context.
