India Block Leaves Fingerprints as Kalshi Overtakes Polymarket in $454M Crypto Volume Week

COLOMBO regional desk. The prediction market story everyone is chasing in New York and London has a quieter chapter that begins in Mumbai, Karachi and Dhaka. A year ago Polymarket sat on roughly 91 percent of weekly crypto-themed event contract volume against its US-regulated rival Kalshi. By the week ending May 17, Artemis data put Kalshi at $454.2 million in spot turnover for that category against Polymarket's $297.1 million, a roughly 60-40 inversion on a combined $751.3 million week. The numbers are American. The triggers are not.

Polymarket's regulatory bruising over the last two quarters reads like a South Asia macro brief. The platform was firewalled out of India earlier this year, severing access to one of the largest English-speaking retail crowds in crypto. That single jurisdictional cut matters more than the headline suggests. Indian traders had become a meaningful slice of the offshore prediction market base, especially for cricket-adjacent political bets and global crypto event contracts priced in stablecoins. When that pipe closed, the volume did not migrate to a domestic substitute. It simply stopped showing up on Polymarket.

Bangladesh and Pakistan-based traders, who often routed through the same offshore on-ramps as Indian counterparts, faced collateral friction as compliance teams tightened KYC nets across the subcontinent. Sri Lankan and Maldivian retail had always been a smaller tail, but the regional tone shifted in the same direction. The path of least resistance for a South Asian holder of USDT looking to take a position on a crypto outcome now runs through whichever venue can survive a regulator letter.

That is what Kalshi has been quietly selling. The TRON integration in December brought native USDT deposits inside the wallet, an underrated win for users in markets where stablecoin liquidity dwarfs domestic banking rails. Pakistani and Bangladeshi traders who hold dollar-pegged tokens precisely because their home currency wobbles read that change as a door opening, not a feature note.

The Coatue-led $1 billion round at a $22 billion mark gave Kalshi the budget to push event contracts into Robinhood and WeBull, while CNN and CNBC partnerships handed it a broadcast surface no offshore venue can match. For the diaspora investor in Dubai or Singapore watching CNBC Asia at midnight, Kalshi is now simply visible in a way Polymarket cannot be.

Polymarket has not lost dollars. It has stopped adding them. The Rhode Island AG suit, the House Oversight probe and the Ninth Circuit ruling on Nevada compound the India block in different ways, but the South Asian read is cleaner than the American one. Cut a platform off from the subcontinent and the growth curve flattens. The 91-to-39 inversion is not coincidence. It is a map of where the regulators pushed and where the stablecoin flows went next.
