Kalshi Files for S&P Perps

The Signal

Kalshi filed with the CFTC to launch equity-index perpetual futures, including a “US500” contract tied to the MerQube U.S. Large Cap Index, according to CNBC and Reuters.

The filing pushes Kalshi further outside its original event-contract lane and into direct competition with CME, Cboe, crypto perp venues, and retail derivatives brokers. The company already received CFTC approval in late May for crypto perpetuals and filed last month for precious-metals perps; Tuesday’s package adds equity indexes and copper.

Kalshi is trying to turn its CFTC-regulated prediction market status into a broader derivatives distribution wedge. Binary event contracts got the company mainstream attention. Perps would give it a product with deeper liquidity, higher repeat usage, and a much larger addressable trading market.

The Mechanism

• Kalshi is expanding from event outcomes to continuous exposure. Perpetual futures do not resolve on a discrete event date; traders hold long or short exposure indefinitely, with funding payments keeping the contract aligned to the reference index. That gives Kalshi a very different revenue and liquidity profile from “Will X happen?” markets.

• The product puts Kalshi on traditional exchange turf. A US500 perp gives retail and active traders leveraged index exposure without rolling quarterly futures or owning ETF shares. CME and Cboe dominate regulated U.S. index derivatives; Kalshi is testing whether a prediction-market-native venue can compete on UX, contract design, and onboarding.

• Data licensing becomes part of the moat. The filings cite reference and market data support from ICE Data Services and FactSet, while CNBC reports the US500 contract would track MerQube’s large-cap index rather than simply list a contract directly on the S&P 500 brand. That structure lets Kalshi mimic broad U.S. equity exposure while managing index licensing and regulatory constraints.

• Perps diversify Kalshi away from politically exposed volume. The company is still dealing with CFTC review of mention markets and election-trust criticism from officials. Index, metals, copper, and crypto perps move activity toward financially native contracts with clearer hedging and speculation use cases.

• Crypto venues set the liquidity benchmark. Hyperliquid traded nearly $200 billion in perps over the last 30 days with more than $11.5 billion in open interest, according to Benzinga/Yahoo Finance. Kalshi cannot match that scale immediately, but it can offer U.S. regulatory status where offshore and onchain venues carry access, custody, and compliance friction.

• The CFTC now has two Kalshi tracks to manage. One track is event-contract scrutiny: elections, sports, mentions, and manipulation risk. The other is conventional derivatives expansion: crypto, metals, copper, and equity-index perps. Kalshi benefits if regulators treat the second bucket as closer to ordinary futures market structure than controversial prediction markets.

The Landscape

Market Position
Kalshi is repositioning itself as a regulated retail derivatives venue, not just a prediction market exchange. The sequence is clear: crypto perps approved in late May, metals perps filed in July, equity-index and copper perps filed on Aug. 18. If approved, the company would offer continuous markets in assets with far larger baseline trading demand than most event contracts.

Polymarket remains the higher-valuation consumer prediction-market brand, with Reuters previously reporting talks to raise roughly $1 billion at a valuation above $20 billion. But Polymarket’s banking and U.S. regulatory path remain messier after reports that JPMorgan cut the platform as a banking client over compliance concerns. Kalshi’s bet is the inverse: accept heavier CFTC oversight, then use that status to list products closer to mainstream derivatives.

Regulatory Environment
Kalshi’s perp filings land while the CFTC is already reviewing parts of the prediction-market product stack. Mention markets are under scrutiny, election officials are warning about odds being misread or manipulated, and sports-adjacent contracts remain politically sensitive. Equity-index perps give Kalshi a cleaner argument: these are financial derivatives, not contracts on civic or reputational events.

Approval is not automatic. The CFTC will need to assess contract design, reference pricing, margining, leverage, funding mechanics, market surveillance, and whether a prediction-market DCM can safely support products that look more like perpetual futures from crypto exchanges than traditional U.S. futures. A green light would widen the path for regulated U.S. perp products beyond crypto.

Key Data

• Aug. 18 filing: Kalshi filed with the CFTC for equity-index perpetual futures, including a US500 product tied to MerQube’s U.S. large-cap index, per CNBC.

• Asset-class expansion: Kalshi has now pursued perps across crypto, precious metals, copper, and equity indexes since receiving CFTC approval for crypto perps in late May.

• Reference-data stack: Reuters reports Kalshi’s equity-index perp proposal uses market and reference data support from ICE Data Services and FactSet.

• Onchain benchmark: Hyperliquid processed nearly $200 billion in perp volume over the past 30 days and carried more than $11.5 billion in open interest.

• Institutional signal: Duquesne Family Office disclosed a $23 million stake in Hyperliquid Strategies, a public-market vehicle tied to Hyperliquid token exposure.

What’s Next

The next catalyst is the CFTC’s response to Kalshi’s equity-index and metals perp filings. Approval would give Kalshi a regulated U.S. path into perpetual futures at the same time offshore and onchain venues dominate the format. Pushback would keep Kalshi’s expansion tied more tightly to event contracts, where the company is already absorbing scrutiny from regulators, banks, and election officials.
