Maryland election contracts draw trading as prosecutor receives investigation request

Maryland election markets on Polymarket and Kalshi have attracted trading activity despite the state’s election betting ban, according to RG. Maryland’s elections administrator has asked the state prosecutor to investigate whether the contracts violate that prohibition.

Maryland trading across two platforms

Polymarket had 20 Maryland election markets with about $599,500 in volume as of Sunday morning, according to RG. The 1st District accounted for the largest share, at about $98,800.

Andy Harris was priced at about 86.5 percent in that district’s market. That figure reflects the market’s pricing, not an election result.

Kalshi showed about 400,500 contracts across 27 Maryland events, according to RG. Those figures measure contract activity and event coverage, rather than the dollar volume reported for Polymarket, so they do not support a direct comparison of trading value.

Legal question remains unresolved

The administrator’s request puts the contracts’ compatibility with Maryland’s ban before the state prosecutor. The supplied reporting does not establish whether an investigation has begun or whether any violation has been determined.

What it means for prediction markets

• Legal status is the central uncertainty: The investigation request concerns whether these contracts violate Maryland’s election betting ban; it is not a finding that they do.
• Platform totals require care: Polymarket’s approximately $599,500 in volume and Kalshi’s approximately 400,500 contracts are different measures and should not be combined.
• Prices are a snapshot: Harris’s approximately 86.5 percent pricing describes the reported market assessment, not a confirmed outcome.
