Kalshi WTI Perpetual Futures Filing: A Regulated Oil Perp That Still Sleeps on Weekends

Kalshi filed a proposal with the CFTC on Wednesday, October 7 for a WTI crude oil futures contract that never expires, according to Bloomberg via Rigzone. If approved, it would be the first crude-linked perpetual futures contract on a regulated US platform. The detail that matters for anyone trading oil perps on Hyperliquid is the schedule: the Kalshi WTI perpetual would trade 24 hours a day, five days a week. Weekends stay off the regulated book.

What the Kalshi WTI Perpetual Futures Filing Actually Proposes

The contract is tied to the West Texas Intermediate benchmark and would have no fixed expiry, per Rigzone. The CFTC has 45 days to approve or disallow it. Exchanges cannot self-certify perpetual futures the way they list other event contracts, so this one goes through full review.

Not every report agrees on the expiry. Prediction News notes that some outlets describe a contract that expires once per decade, while others describe no expiry at all. The same report frames the filing as a test of whether the CFTC will reuse the accelerated path it took with Kalshi's US500 stock index perpetual.

The public reporting does not include the funding formula, margin requirements or contract size. Those are the numbers that decide how the product trades, so treat any claim about Kalshi oil funding as unconfirmed until the filing text or a CFTC notice is public.

Why a 24/5 Oil Perp Leaves the Weekend Onchain

Bloomberg reported that the 24/5 structure was designed to address regulatory concerns raised by the trading community, according to Rigzone. That concern has a clear history. CME announced it was shelving its round-the-clock oil contract the Friday before Kalshi's filing, after a CFTC block opened a months-long review of whether weekend trading fits a physical market that needs reliable benchmark prices to sell cargoes.

Kalshi has used this template before. When it filed for gold, silver and platinum perpetuals in July, the proposal also started at 24 hours a day, five days a week, matching the underlying metals markets, and Kalshi said it would assess longer hours later, Finance Magnates reported.

The result is a regulated oil perp that removes the expiry and the roll, but keeps the Friday close and the Sunday reopen. Any headline that lands on a Saturday still gets priced first on venues that never close. Hyperliquid's HIP-3 oil markets, which trade[XYZ] has offered since October 2025 according to crypto.news, are one of them.

How Much of the Weekend Oil Move Already Happens on Hyperliquid

The best public evidence comes from the joint submission Hyperliquid Policy Center and trade[XYZ] sent to the CFTC on August 26. According to crypto.news, the filing says that after the Middle East conflict disrupted energy exports on February 28, about two-thirds of the oil price move between Friday's close and Sunday's benchmark reopen happened onchain. A study cited in the same filing found that across nearly 75% of weekend closures, the perpetual finished closer to Sunday's opening price than to Friday's close.

An independent read from Castle Labs, covering February 27 to March 16, gives the weekend-by-weekend detail. On the first weekend, CME WTI closed at $67.29 and reopened at $75. The Hyperliquid xyz:CL contract reached about $70.80, roughly 45% of the gap, and was capped by its ±5% discovery bounds. On the second weekend it captured 68% of a move from $91.27 to $98.

The same study shows the cost side. Simulated slippage on a $1M order was 15.4 bps on Hyperliquid against 0.79 bps on CME, and depth within ±2 bps was $152K against $19M. Median trade size was $543 onchain versus $90,450 on CME. The weekend book leads on direction, but it is thin, and it is mostly small tickets.

What Changes for Oil Perp Orderflow if Kalshi Gets Approved

The weekday picture could shift. Kalshi already reports commodity volume near $400 million as of early September, almost four times what its crypto markets did at the same point in their lifecycle, per Rigzone. A US-regulated WTI perp would give American retail a direct way to take oil exposure without rolling futures, which competes with HIP-3 oil during the hours both venues are open.

The weekend picture does not shift. Between Friday and Sunday evening, a 24/5 Kalshi contract has no price, so the only continuously traded WTI perp reference stays onchain. That creates a new, observable spread to watch: Kalshi's Friday close against Hyperliquid's Sunday price, converging when Kalshi reopens. It is the same structure the Castle Labs data measured against CME, now with a second regulated venue on the other side.

Two caveats matter. First, the CFTC has not approved any energy perpetual, and Chair Michael Selig has said the agency wants a "clear, data-driven record," per crypto.news. Second, CME has objected to perps and sued the CFTC over Kalshi's crypto versions, according to Rigzone. A 45-day clock is not a guarantee of a decision in Kalshi's favor.

Reading the Weekend Oil Book Before Monday

If you trade oil perps, the useful part of this filing is the calendar it implies. Weekend sessions are where informed flow has the least competition, and also where depth is thinnest. Three things are worth tracking on CL and BRENTOIL over a weekend: taker-side CVD, to see whether aggressive buyers or sellers are driving the move; open interest, to see whether new positions are opening or old ones are closing; and the distance between the perp and Friday's regulated settle.

When a move runs into the discovery bounds, as it did on the first weekend in the Castle Labs sample, the perp understates the true gap. A flat price at the band with CVD still pushing in one direction is a sign that Monday's open has further to go.

Buildix covers Hyperliquid HIP-3 markets natively, including the oil perps, with CVD, order book imbalance and VPIN on each pair. The screener puts funding and open interest for HIP-3 and crypto markets in one table, so a weekend imbalance in oil shows up next to everything else you watch.

Kalshi is asking the CFTC for a regulated oil perp that sleeps on weekends. Whatever the decision in 45 days, the Saturday tape will still print on an onchain book first.
