The nominal trading volume of the prediction market reached $113.8 billions in the second quarter, and Talos integrated Kalshi trading.

Odaily reported that institutional crypto trading platform Talos has integrated prediction market operator Kalshi, allowing some clients to trade Kalshi event contracts and crypto perpetual contracts via existing digital asset trading infrastructure, without needing a separate connection.

Talos will offer algorithmic order types such as Iceberg, TWAP, POV, as well as multi-leg execution for perpetual-to-perpetual and perpetual-to-spot spread trading. Institutional clients can also use its RFQ platform to execute block trades for Kalshi contracts through participating OTC liquidity providers.

Talos plans to expand its trader software to brokers and trading platforms later this year, enabling them to directly offer Kalshi event contracts to clients where permitted, and to launch a unified prediction market data feed, standardizing event, trade, order book, open interest, and implied probability across multiple platforms.

According to a CoinGecko report, the notional trading volume of prediction markets reached $113.8 billion in the second quarter, up 48.7% quarter-on-quarter; the notional trading volume in June reached $52.8 billion, setting a new monthly record. Kalshi's market share rose from 42.4% in the first quarter to 58.9%, while Polymarket dropped from 35.8% to 30.2%.
