The crypto market has flipped bullish over a three-day stretch, adding roughly $313 billion in total market value as the capitalization climbed from $2.19 trillion to $2.5 trillion. Data from CoinGlass showed that Wednesday, August 19, produced the largest short liquidation in crypto history, with more than $2.7 billion in leveraged positions wiped out.
Kalshi set two records the same day. According to Artemis, daily crypto spot volume reached a new high of $268.89 million, while daily crypto perpetual-futures open interest climbed to $18.69 million. The spot figure does not reflect a traditional order book. Kalshi’s crypto event contracts are yes-or-no binaries tied to whether an asset closes above a given level by a set date, meaning volume on those books reflects attention rather than directional conviction.
Open interest, by contrast, shows conviction. Kalshi launched CFTC-regulated crypto perpetual futures on May 29, 2026, and trading formally began on June 3. Volume cleared $1 billion within the first week. Open interest rose from about $2 million on June 4 to the August 19 record, overtaking a prior benchmark of $17.98 million reported earlier in August. Traders holding positions overnight through a rally are effectively betting on continuation, which makes the record open interest reading more significant than the spot volume record.
The absolute numbers remain small compared with offshore venues. Hyperliquid, for example, had about $11.7 billion in daily open interest across 377 pairs. Still, Kalshi operates with a CFTC license and onshore US access, making the venue a regulated alternative for leveraged crypto exposure that previously flowed mostly offshore.
Kalshi’s initial offering listed 13 CFTC-approved crypto perpetual-futures contracts, including Bitcoin, Ethereum, Solana, XRP and Shiba Inu. Maximum leverage was listed at 5.9x for Bitcoin, 4.5x for Ethereum, and 2.0x for Shiba Inu. The platform uses isolated and cross-margin options, with funding payments charged every eight hours to keep perpetual prices aligned with spot markets.
The broader context is equally notable: prediction-market platforms have spent the past year expanding from election contracts into financial markets. Kalshi’s record activity may not yet rival Binance or Hyperliquid, but the trajectory since June suggests US traders are increasingly exploring CFTC-regulated crypto derivatives.
