Market outcomes
| Obama arrested before 2027? | 8% YES | 92% NO |
The market concerns whether former US President Barack Obama will be arrested and taken into physical custody by law enforcement authorities before the close of 2026. The resolution criteria specify formal detention meeting standard arrest procedures—handcuffing, booking, or voluntary surrender in response to a warrant—rather than mere questioning or summons. The current order book on Polymarket implies an 8% probability of this outcome, reflecting trader assessment across the settlement window of roughly two years.
No former US president has been arrested whilst living, though several have faced criminal investigations post-presidency. The closest historical parallel is Donald Trump's 2023 indictments and subsequent arraignments, which involved voluntary surrender and formal booking but occurred whilst Trump held no office. Obama has faced no criminal charges, indictments, or formal investigations by federal prosecutors as of late 2024. The 8% probability appears calibrated to tail-risk scenarios involving unforeseen developments rather than current legal exposure.
Traders monitoring this market should track developments from the Department of Justice, potential congressional investigations, and any announcements from state-level prosecutors. The market's timeframe excludes any proceedings initiated after 2026, meaning charges filed in late 2026 would require arrest within weeks to resolve affirmatively. Media reporting on investigations into Obama-era officials—such as those concerning the origins of the Russia investigation—occasionally surfaces but has not produced charges against Obama himself. The probability remains heavily weighted toward "No" given the absence of active legal jeopardy.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Obama arrested before 2027?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$7K in lifetime turnover and $14K of resting liquidity puts this market in the below the median by volume for obama contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.
The market has been open for 6 months — long enough that the order book is mature and price is well-anchored to fundamentals.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
