Cantor Fitzgerald has launched institutional block trading in Kalshi event contracts, becoming one of the first full-service investment banks to offer institutional access to negotiated event-contract trades on a CFTC-regulated exchange. The August 19, 2026 rollout positions Cantor as an Introducing Broker for large prediction-market trades, with Susquehanna Predictions supplying institutional-scale pricing and liquidity.
The launch is live institutional access, not a pilot program. Cantor said it commenced institutional trading for prediction markets on August 19, arranging and facilitating institutional-size block trades in event contracts, according to its announcement. For related coverage, see Twenty One Rings NYSE Bell, Starts Trading as XXI.
Cantor's role is that of an Introducing Broker rather than the exchange itself. The bank arranges and facilitates the trades through Kalshi's block trading framework, executed away from the central order book, while Kalshi remains the venue where the contracts trade and clear.
Susquehanna Predictions will provide the institutional-scale pricing and liquidity behind the coverage. The involvement of a dedicated liquidity provider is central to making large negotiated trades workable, since block sizes far exceed typical retail order-book depth.
Kalshi is the initial venue, and Cantor said additional venues are expected to follow. That framing signals a broader expansion plan rather than an exclusive tie-up, echoing the way regulated prediction-market infrastructure has been widening its scope, including Kalshi's recent move to file perpetual futures on U.S. stocks and copper.
Pascal Bandelier, quoted in Cantor's release, framed the strategic logic simply.
"Prediction markets are the next one." — Pascal Bandelier, Cantor Fitzgerald
A block trade on Kalshi is a negotiated transaction between two counterparties, executed away from the public order book and then reported to the exchange. That off-order-book structure lets large participants transact size without moving the visible market against themselves.
Kalshi sets published minimums for these trades: 25,000 contracts for non-sports event contracts and 50,000 contracts for sports event contracts, per its institutional materials.
Institutional threshold 25,000 contracts minimum for non-sports event block tradesEvent contracts settle at a binary $1 or $0 per contract, depending on whether the specified outcome occurs. That fixed settlement model caps the value of each contract and defines the payoff structure institutions are transferring risk around.
Cantor described itself as one of the first full-service investment banks to offer institutional access to block trading in event contracts on a CFTC-regulated exchange. Joe Grubb, cited in the release, framed the offering around large institutional risk transfer, the capacity to move sizable positions between counterparties.
The regulatory foundation sits with Kalshi's registered structure. The CFTC said on August 29, 2024 that Kalshi Klear LLC received DCO registration and that affiliate KalshiEx LLC is registered as a designated contract market, according to the regulator.
That regulated exchange-and-clearing framework is the main compliance basis for Cantor's institutional launch, giving banks and funds a familiar oversight structure. Cantor's broader crypto-market footprint has included work such as its SPAC merger talks with Securitize and earlier coverage that trimmed its MicroStrategy target while keeping Bitcoin exposure.
Concrete adoption metrics were not disclosed. Neither Cantor nor Kalshi published launch-day block-trade volume, notional value, or confirmed onboarding totals tied to the rollout. Secondary coverage attributed a figure of roughly 3,000 reachable institutional clients, but that claim comes from unconfirmed reports via the Wall Street Journal and does not appear in Cantor's own release.
The launch arrives against a constructive crypto backdrop. Bitcoin was up 5.44% over 24 hours at the time of research, trading near $68,231, though that move does not prove a direct reaction to the Cantor-Kalshi announcement.

Prediction markets themselves have become a closely watched gauge of macro expectations, with Polymarket, Kalshi, and Myriad putting September Fed hold odds in the mid-70s.
