US government GlobalFoundries stake trades far apart on the major desks

Kalshi 69% vs Polymarket 78%
record: CMSIG20260725DV02 | category: cross-venue-divergence | target: CM-EVT-TDJHRGQTY1 | published: 2026-07-25
4-bullet brief | narrative
  • Polymarket prices a US federal stake in GlobalFoundries at 78%, Kalshi at 69%, a 9pp gap
  • Polymarket is the higher-priced venue but carries less than a third of Kalshi's cumulative volume ($5K vs $17K)
  • Kalshi's larger pool may be discounting resolution ambiguity around what constitutes a qualifying stake; Polymarket may be pricing in pending CHIPS Act mechanics
  • Claim resolves if any federal entity holds above 0% equity in GlobalFoundries at any point before the horizon
