NextFin News - Cantor Fitzgerald said Wednesday it will give its roughly 3,000 institutional clients access to prediction-market trading on Kalshi, becoming one of the first full-service Wall Street brokers to route hedge funds and family offices into a CFTC-regulated exchange for event contracts. The bank will act as an introducing broker for block-sized trades, with Susquehanna International Group providing pricing and liquidity, a move that treats yes-or-no contracts on everything from weather to corporate earnings as a mainstream risk-transfer tool rather than a retail betting product.
The announcement lands at a moment when prediction markets have already stopped being a niche. Combined monthly global trading volume on Kalshi and Polymarket, the two largest platforms, rose from less than $5 billion in September 2025 to about $24 billion in April 2026, according to a Pew Research Center analysis of exchange data compiled by a digital assets information firm. What began as a vehicle for retail wagers on elections and sports is being rebuilt, piece by piece, into institutional plumbing. Cantor's move is the clearest sign yet that the rebuild has reached Wall Street's front door.
The Deal: A Broker, a Market Maker, and a Block-Trading Framework
Cantor's roughly 3,000 institutional clients, which range from family offices to hedge funds, will gain full access to Kalshi's suite of events-based, yes-or-no contracts, including those tied to weather, commodities and corporate results. The bank will serve as the broker, arranging and facilitating the execution of institutional-size block trades in event contracts, enabling clients to negotiate block trades at a single price through Kalshi's block-trading framework, away from the central order book. Cantor is also considering reselling contracts it secures to other investors, and clients may propose topics for new event contracts.
The structure is deliberate. Kalshi's market maker, Susquehanna International Group, provides the pricing and liquidity; Cantor provides the client relationships and the brokerage wrapper. In a statement, Pascal Bandelier, co-CEO and global head of equities at Cantor, framed both the firm's history and the thesis of the launch:
"Cantor has spent more than eighty years building institutional access to new markets, and prediction markets are the next one. Prediction markets are growing rapidly, but institutional participation has not kept pace because investors have lacked the ability to transact at scale on a regulated exchange. The liquidity is here. With the launch of block trading, institutional investors can now access block trading in event contracts."
The missing ability was not access to a screen. It was the ability to move size. A retail account can buy a few hundred yes-or-no contracts without moving the market; a hedge fund hedging a multi-million-dollar exposure cannot. Block trading, negotiated away from the central limit order book at a single price, is the same infrastructure that long ago made equities and bonds usable for large accounts. Cantor is importing that convention into a market that, until now, has been built for small tickets.
From $5 Billion to $24 Billion: The Volume That Made Wall Street Notice
It is easy to dismiss prediction markets as a speculative fad until the numbers force a second look. Monthly transaction volume across the two leading platforms grew roughly five-fold in the seven months to April 2026 alone. The user base expanded even faster: unique participating wallets more than tripled to about 840,000 in the six months leading into February 2026, according to a separate analysis of on-chain activity. Kalshi's own scale underscores the shift — the exchange crossed $100 billion in lifetime notional volume in mid-2026, and its markets tied to the 2026 FIFA World Cup generated roughly $13.8 billion in volume, an all-time event record for the platform.
Capital has followed the volume. Kalshi raised $1 billion in December 2025 at an $11 billion valuation, then another $1 billion in May 2026 at $22 billion, according to private-market data. The company also launched perpetual futures that cleared $1 billion in volume within a week of debut. This is not the footprint of a novelty; it is the footprint of a market that found product-market fit faster than the regulatory system expected.
The regulatory system, for its part, has stopped fighting and started writing rules. The CFTC launched a rulemaking process for prediction markets in 2026, after dropping its appeal of the Kalshi litigation in 2025 and signaling that it views event contracts as futures under its exclusive federal authority. That clarity is what made Cantor's participation possible. A Wall Street broker does not build brokerage infrastructure around a legal gray zone.
What the Trade Actually Is — And What It Is Not
An event contract is simple in structure and powerful in use. It pays out a fixed amount if a specified, observable event occurs — whether a named hurricane makes landfall in a given state, whether a company's quarterly revenue exceeds a threshold, whether a commodity price closes above a level on a given date — and nothing if it does not. That binary payoff is different from an option, which carries a volatility surface, time decay, and a strike grid; and it is different from insurance, which settles claims through adjusters over weeks or months.
The institutional pitch is that event contracts fill a gap those two instruments leave open. Insurance is slow, relationship-based, and poor at covering parametric risks that resolve cleanly against data. Options cannot express many real-world outcomes at all — there is no listed option on whether next quarter's iPhone sales beat a number. An exchange-traded, exchange-cleared binary contract settles quickly, transparently, and without a claims process. Max Crowley, Kalshi's vice president of business development, put the demand side plainly:
"There is already demand among institutional investors to manage risk tied to specific events separately."
Joe Grubb, head of business development at Susquehanna Predictions, went further, describing the opportunity as a new channel of risk transfer:
"We believe the next area of material growth for prediction markets will be large institutional risk transfer. We are able to price and execute custom, tailored contracts for institutional counterparties desiring to hedge both general market and bespoke industry risk currently unserved by traditional insurance markets. Our ability to do so quickly and at scale will provide a valuable solution to this unmet market need."
But the product's current composition is a warning as much as a promise. Sports, politics and cryptocurrency together accounted for 91% of global trading volume on Kalshi from July 2024 through early 2026, according to the Pew analysis. Politics alone made up 90% of Kalshi's volume in October and November 2024, around the U.S. presidential election — a period when the platform had not yet introduced sports trading. That concentration matters. Election and sports contracts are clean to resolve and easy to market to retail traders; they are not obviously the contracts a pension fund or a corporate treasurer needs to hedge a balance sheet.
The Counter-Thesis: Liquidity, Not Legitimacy, Is the Real Bottleneck
The strongest argument against reading Cantor's move as a regime change is simple: a broker on-ramp does not create a market. Liquidity begets liquidity, and the deep end of Kalshi's pool sits in politics and sports, not in the bespoke industry hedges that Susquehanna describes. An institution that wants to hedge a custom exposure needs a counterparty willing to take the other side at size, every time. If the only deep markets are "Will the Fed cut in September?" and "Which team wins the Super Bowl?", then block trading solves an access problem without solving a hedging problem.
There are also legal headwinds that a press release cannot dissolve. Nevada gaming regulators sued Kalshi in February 2026, and Arizona's attorney general filed lawsuits against the platform in March, reflecting state-level pushback against event contracts that resemble sports wagering. The CFTC's claim of exclusive federal authority is the shield Cantor is relying on, but the boundary between a regulated event contract and a bet remains politically contested, and contested boundaries produce litigation risk that sits on a broker's balance sheet.
Nor is market integrity a settled question. In March 2026, both Kalshi and Polymarket publicly outlined measures to curb insider trading, restricting participants with potential access to non-public information. The concern is inherent to the product: the people best positioned to hedge an event are often the people who know the outcome first. Exchange transparency helps, but it does not eliminate the problem.
The answer to the liquidity objection is the deal itself. Cantor brings the order flow; Susquehanna brings the market-making; the block framework lets large trades clear without walking the price through a thin book. That is exactly the right architecture. But architecture is not volume, and this thesis will be proven or disproven in the tape, not in the announcement.
Cyclical Hype, Structural Shift: Separating the Two
The honest read of this moment requires separating two forces that are easy to blur. The cyclical leg is the 2024 election cycle, the surge in crypto-rails trading, and the speculative rush into anything that could be bet on. That leg is mean-reverting by nature: event calendars cluster around elections, volume spikes around geopolitics, and retail enthusiasm fades when the news cycle does. The 90% political concentration in late 2024 is the clearest evidence of this — a single event can dominate an entire platform's volume for a quarter, and then cannot be repeated.
The structural leg is different, and it is what Cantor is betting on. A structural shift is a change in rules, infrastructure, or industry structure that does not revert on its own. Four things qualify here. First, federal regulation: the CFTC is writing the rulebook rather than litigating the market out of existence. Second, regulated exchange and clearing infrastructure now exists and is being integrated — the Robinhood-Susquehanna joint venture closed its acquisition of the CFTC-licensed MIAXdx exchange in January 2026. Third, Wall Street distribution is arriving: Cantor is not a crypto native; it is an 80-year-old institutional broker, and its participation signals that event contracts can sit inside conventional compliance and custody frameworks. Fourth, the product solves a genuine, persistent gap: parametric, fast-settling, transparent hedging for risks that insurance handles poorly and derivatives cannot express.
These two legs point in different directions. The cyclical leg says volume will fall back from its peak once the event calendar thins. The structural leg says the baseline from which it falls back is now an order of magnitude higher than it was two years ago, and that institutional adoption will compound from that higher floor. Both can be true at once.
My judgment: this is a structural shift in how event risk is transferred, arriving with a cyclical volume hangover attached. The institutional plumbing is real and will not be un-built; the retail frenzy that financed it will cool. The practical consequence is that adoption will be gradual and concentrated in contracts with clean, fast-resolving, data-verified outcomes — weather, macro prints, commodity levels — rather than the messy, slow-resolving risks that dominate corporate hedging books today.
What to Watch: The Signal That Proves or Disproves the Thesis
The beneficiaries are clear if the thesis holds. Kalshi gains distribution and a legitimacy stamp that no amount of venture funding could buy. Susquehanna captures market-making fees on a new institutional flow. Cantor earns brokerage revenue and, more importantly, deepens client stickiness by offering a tool competitors do not yet have. On the other side of the trade, traditional parametric insurers face a faster, cheaper substitute for a slice of their book; sportsbooks and retail-first prediction platforms face a Wall Street competitor with deeper pockets and institutional relationships.
The forward look should be split by horizon. In the short term, expect announcement-driven attention and a volume spike in the most headline-friendly contracts — Fed decisions, weather events, high-profile earnings. In the medium term, the question is whether bespoke contracts actually launch and clear at scale; watch for Cantor and Susquehanna to announce custom, client-proposed event contracts, which would be the first real evidence that the hedging use case is working. In the long term, the test is whether event contracts become a standard line item in institutional risk books, sitting alongside options and insurance rather than replacing either.
Scenarios are straightforward. The base case is that Cantor routes meaningful block flow and Kalshi's institutional share of volume rises steadily through 2027. The upside case is that more full-service brokers follow — "the first full-service bank" becomes a crowd — and event contracts begin to rival parametric insurance premium in niche perils. The downside case is that state-level legal challenges persist, bespoke liquidity stays thin, and institutional event contracts remain a political-and-sports novelty with a Wall Street wrapper.
One falsifying signal cuts through the noise. If institutional block trades remain below 5% of combined Kalshi-Polymarket monthly volume through the end of 2026, the structural-shift read is wrong, and this is a distribution story without a product story. That threshold is observable, it is specific, and it will be known within months.
The closing judgment is this: Cantor is not discovering a new casino. It is discovering that a casino's plumbing can hedge a balance sheet — and that the difference between the two is who is allowed to sit at the table.
