Kalshi Wants a 24/7 Stock Market. The Problem Is the Closing Bell.

Kalshi, the CFTC-regulated platform best known for letting people bet on elections and sports, wants to list perpetual futures on roughly 60 major U.S. stocks and exchange-traded funds — Tesla, Apple, and Nvidia among them — and trade them around the clock. The pitch writes itself: never wait for the opening bell again, bet on Nvidia at 3 a.m. like a crypto trader bets on Bitcoin. The appeal is real, and Wall Street is listening. But the product Kalshi is copying has a catch that works fine for cryptocurrency and quietly breaks for a stock that closes at 4 p.m.

Perps were built for a market that never sleeps

A perpetual future is a futures contract with the expiration date stripped off. In crypto it became the dominant way to trade: instead of one price at one maturity, you hold a position that stays open as long as you want while a periodic "funding" payment between longs and shorts keeps the contract tethered to the spot price. You never have to own the asset. Offshore exchanges Binance and Bybit run a global perpetual market worth roughly $90 trillion a year — the pool Kalshi is now aiming at.

The company is already well into this push. The CFTC approved its Bitcoin perpetual in May 2026, and the contract has done about $44 billion in notional volume since. In September the agency cleared perps on gold and silver, Kalshi's first non-crypto products, and the exchange has filed for altcoins, copper, currencies, and stock-index contracts. The single-stock and ETF batch is the next step.

This is the prologue to something bigger than the product list. Kalshi is a private company racing to a roughly $40 billion valuation, up from $22 billion in May, on annualized revenue of around $4 billion that largely comes from sports event contracts — not from perps, which it currently runs at zero fees. The equity program is its graduation from a betting site into a general-purpose derivatives exchange that can charge fees on a market an order of magnitude larger than the one it already monetizes.

The flaw: your hedge doesn't exist after the bell

The perp design rests on an assumption that is true for Bitcoin and false for a U.S. stock. A perpetual must periodically snap back to the spot price, or it stops being a future and just becomes an opinion. For Bitcoin, that anchor is always available, because Bitcoin trades 24/7 — there is always a spot price to arbitrage back to. The funding rate works because arbitrageurs can actually execute the other side at any hour.

A stock does not trade at 2 a.m. There is no authoritative Nvidia price until 9:30 New York time, and — the part that matters more — there is nothing to buy or sell as a hedge when the perpetual is open. The guy offering the other side of your 3 a.m. position cannot buy the stock to offset it, because the exchange is closed. The specific, liquid hedge the position needs simply does not exist during exactly the hours the market is open. That is basis risk, and it is the reason this product is structurally different from its crypto template.

The practical consequence lands on whoever trades the gap. Kalshi regulators cite the obvious risks: a trader with news that would move Nvidia could trade the perpetual all night before the underlying market can react, and if the stock is halted on a news release, the perpetual keeps trading without the coordinated stop the tape normally enforces. Between sessions the contract floats on whatever private mark its dealers set, unmoored from any arbitrageable reality until the bell. A retail trader at 3 a.m. is not trading a price others can prove wrong for six hours; they are trading a price nobody can arbitrage until morning. The funding and spread edges accumulate to whoever is running the other side — which is exactly what a market maker wants.

The fight happens in public stocks, not a private one

Kalshi is not an investable abbreviation for a retail shareholder, but the fallout from this program is showing up in tickers you can buy. When the CFTC approved the first Bitcoin perps in early June, shares of CBOE fell about 8% and Nasdaq roughly 5%; CME and ICE slid too, as analysts flagged perpetuals as a threat to the exchanges' core franchise.

The incumbent reaction is also a legal one, and it is where the single-stock part gets hard. CME Group is already suing the CFTC over the classification of perps — arguing the agency's approval was wrong — and that unresolved case hangs over every later filing, including this one. On jurisdiction, Citadel Securities has urged regulators to keep equity-linked perpetuals under SEC oversight rather than CFTC control, warning that a second market with different rules and a different watchdog would create a "parallel market" for the same stocks. That matters here specifically: broad stock indices qualify for CFTC treatment, but the individual names in Kalshi's 60-contract batch are securities, and securities are the SEC's domain. The approval Kalshi needs is not a switch but a stretch of contested, multi-party litigation where incumbents and a second regulator both have standing to push back. Governance determines how fast — or whether — this particular threat moves.

The verdict, in plain terms: Kalshi is betting that an always-open derivatives market can muscle into equities on the strength of the same template that won in crypto, while the listed exchanges are betting that a 24/7 contract on a market that physically closes is a structurally weaker product than it looks. Both can be partly right. The threat to CME and CBOE is real, but it is contested and likely to be drawn out, and the market has already repriced the first approval. As for the product itself, history in derivatives is not kind to contracts whose hedge is unavailable when they trade — an always-open market is not the same thing as a 24/7 one, and everything hinges on whether Kalshi can make the funding mechanism work on a stock nobody can trade, hedge, or price until morning.
