Vitalik Buterin Says He Netted $70,000 Fading Polymarket’s ‘Crazy Mode’ in 2025

His disclosure revives focus on oracle reliability after a hacked ISW map distorted a Ukraine control bet.

Overview

  • Buterin told Foresight News he committed about $440,000 to prediction markets in 2025 and earned roughly $70,000, a gain near 16%.
  • He targets contracts he deems in “crazy mode,” citing examples like wagers on Trump winning a Nobel Peace Prize or the dollar going to zero.
  • He criticized weak oracle safeguards, pointing to a Myrnohrad market tied to ISW maps that shifted after the institute’s X account was hacked.
  • Ukrainian media reported some traders saw payouts above 33,000% on roughly $1.3 million in volume, though platforms did not disclose official totals.
  • He floated fixes that range from using a centralized feed from reputable outlets such as Bloomberg to token‑based voting systems like UMA.
