Polymarket 28% vs Kalshi 14%

4-bullet brief | narrative

Polymarket prices the merger at 28%, Kalshi at 14%, a 14pp spread on the same binding-deal claim.
Polymarket is the higher-conviction venue; Kalshi carries far thinner liquidity at under $3.5K cumulative volume vs $42.9K.
Thin Kalshi pool likely reflects retail absence rather than informed skepticism; Polymarket's deeper book lends its print more weight.
Resolution requires a publicly announced, definitive, binding agreement transferring controlling interest before Oct 1, 2026.
