Security
Polymarket paused international trading after a third-party compromise
International site halted. The company says affected traders will be reimbursed. The US platform was not the one stopped.
Bonuses
Welcome bonuses are not one deposit match
Polymarket US: $10 in, $25 trading credit each side. International Polymarket pays fees. Kalshi varies. Smarkets is 0% for 60 days.
Regulation
Sixth Circuit: Kalshi sports contracts are not swaps
Ohio and Tennessee, 25 Sep 2026. Sports event contracts are not swaps. Metal perps and the CME suit are different dockets.
Metals
Kalshi gold and silver perps are a 40.2 filing, not a CFTC vote
GOLDPERP and SILVERPERP were self-certified under CFTC Reg. 40.2. Cash-settled, no expiry, Pyth oracle. That is not a Commission yes.
Regulation
Kalshi sports is a map now
Third Circuit said swaps. Ninth Circuit said sports betting. New Jersey asked SCOTUS. Sports access is not one national product.
TVL
DefiLlama TVL is not our ranking
Polymarket International $361.1M. Kalshi has no pool TVL. A Llama screenshot is not a Gamma Score.
Watchlist
Predict Fun is watchlist, not a Kalshi alternative
$11.3M on BNB is a catalog hole we closed. It is not a US cash DCM and it is not on the alternatives list.
