1. What did Hypercall report about its trading volume?
Hypercall, an options exchange built on the Hyperliquid blockchain, said on October 14 that it has handled $640 million in notional trading volume since launching on June 1, with more than 80% of that total coming from S&P 500 index options. Open interest stands at roughly $49 million, of which about $47 million sits in the index contracts.
The figures point to an unusual pattern for a crypto-native derivatives venue. Most onchain options platforms built their early reputations on bitcoin (BTC) and ether (ETH) contracts. Hypercall, by contrast, has found its audience among traders who want exposure to the benchmark of large American companies without leaving the blockchain environment where they already keep their collateral.
Notional volume measures the face value of the underlying exposure covered by the contracts, not the premium that buyers actually paid for them. That distinction matters when reading the number. A $640 million notional total does not mean $640 million of capital changed hands; it means the contracts traded referred to that much underlying value. Open interest, the value of positions still outstanding, gives a better sense of how much risk is currently held on the platform, and at about $49 million it remains modest.
2. How do the S&P 500 contracts work?
Each contract carries a $1 multiplier, so every point in the index is worth one dollar at settlement. A call option with a strike of 7,000, for example, pays $100 if the index settles at 7,100. A call pays out when the underlying finishes above its strike price at expiry, while a put works in the opposite direction and pays when the underlying finishes below it. Traders use the two to hedge existing holdings, to speculate on direction, or to take positions on volatility and timing.
Settlement happens in USDC, a dollar-pegged stablecoin, and it is calculated against the average price over the final 30 minutes of trading in Hyperliquid's S&P 500 perpetual futures. Using an average over a half-hour window rather than a single closing print is a common design choice, because it makes the settlement value harder to move with one large trade at the last moment.
Because the contract size is tied directly to index points, a trader can estimate the outcome of a position with simple arithmetic. The buyer of an option pays a premium up front and can lose no more than that amount, while the seller collects the premium and takes on the obligation to pay if the option finishes in the money. That asymmetry is why short-dated options attract traders who want defined risk on a quick view, and why the sellers on the other side of those trades tend to be professional firms that can hedge their exposure.
Hypercall lists daily, weekly and monthly expiries, and it does so at all hours, including weekends. The exchange says most of the activity is concentrated in options that expire the following day. Founder Jake Sylvestre, who answered questions by email, explained that traders can use those short-dated contracts to bet on the next day's move, or they can hold positions for longer if their view extends further out.
3. Why does round-the-clock trading matter?
Continuous availability is the main attraction, according to Sylvestre. He described Hyperliquid as the best venue for trading these markets outside traditional exchange hours. Conventional index options follow the schedule of the exchanges that list them, which leaves gaps overnight and across weekends. Crypto venues have no such closing bell, and traders who want to react to news on a Saturday have few regulated alternatives.
Hypercall's design builds on a broader trend. Traders increasingly use blockchains to gain exposure to traditional markets, including through derivatives. Hyperliquid's decentralized exchange has become a go-to venue for trading and managing risk through perpetual futures, which are contracts without an expiry date, and that has been especially visible on weekends when geopolitical tensions have repeatedly escalated. Hypercall extends the same logic from perpetual futures to options.
The model also changes the job of the market makers who quote prices. Hypercall's liquidity providers hedge their positions on Hyperliquid perpetuals, including during weekends when cash equity markets are closed. Earnings reports, economic data and company announcements can move the shares behind an index while their home exchanges are shut. Sylvestre said the market makers therefore have to price those events continuously rather than waiting for the next opening bell.
4. How does Hypercall compare with Deribit?
The scale of the numbers is small against the established players. Traditional markets for S&P 500 products trade trillions of dollars in notional volume each day, and the largest crypto options venue, Deribit, handles billions of dollars daily. Deribit, owned by Coinbase, mainly lists options on bitcoin and ether. Hypercall's total since June is a fraction of what those much larger venues process in a single session.
Sylvestre said Hypercall is not trying to replace Deribit. In his account, most Hypercall traders have not left that platform; they are instead trading markets that Deribit does not list. That framing places the new exchange as a complement serving a different product set, not a direct rival fighting for the same bitcoin and ether order flow.
The comparison is a reminder that early traction should be read in proportion. A young exchange reporting that a single product makes up the bulk of its volume has found a niche, but it has not yet shown that the niche is deep or durable. Sustained growth in open interest, and the arrival of more liquidity providers, would be stronger evidence than cumulative volume alone.
5. Who provides liquidity, and what runs off-chain?
Two market makers are currently active on Hypercall, and three more are being onboarded. Sylvestre said the identities of the others will be made public over the next few weeks. For an options venue, the number and quality of market makers largely determines how tight the quoted prices are and how large an order can be filled without moving the market, so the expansion from two to five is a meaningful operational step.
Sylvestre also described how the platform divides its work between the blockchain and conventional servers. User collateral is held onchain, but the matching of orders happens off-chain, and parts of margining and liquidation also run off-chain. This hybrid approach is common among high-speed derivatives venues, because matching engines that must respond in milliseconds are difficult to run entirely within the confirmation times of a blockchain. It does mean that users rely on the operator for some functions even though their funds are held onchain.
For readers weighing the platform, the split is worth understanding. Onchain custody limits the operator's ability to touch deposited funds, while off-chain matching and risk handling place trust in the exchange's software and procedures. Neither element is unusual in this segment of the market, but the mix explains how the platform can offer short-dated contracts around the clock.
6. Individual stocks draw broad interest
The index is not the only product attracting traders. Options on SpaceX, Nvidia, Micron and SanDisk together account for more than half of all trades on the platform. Contracts on Apple, Microsoft, Meta, Alibaba, ether and bitcoin follow behind them. Sylvestre said the breadth of interest lies in single stocks, which suggests that demand extends beyond a single headline index.
That mix matters for the platform's outlook. Single-stock options tend to attract traders with a specific view on a company, such as ahead of a product launch or a quarterly report, and those traders may be less likely to treat the venue as a tool for hedging a broad portfolio. A venue that serves both groups can build more varied order flow, though it also takes on the pricing challenge of quoting many more underlying assets.
The inclusion of SpaceX is notable, since it is a company whose shares most retail investors cannot easily trade directly, and onchain derivatives offer one route to expressing a view on it. Crypto-native platforms have repeatedly found demand in assets that are harder to reach through traditional brokerage accounts.
7. Competitors are adding stock options too
Hypercall is not alone in chasing this demand. Bybit began 24-hour trading of options on stock perpetuals on September 17, starting with SpaceX and Nvidia. Binance, the largest crypto exchange by value traded, offers options on more than 1,000 U.S. stocks and exchange-traded funds to eligible users outside the United States.
The moves by larger exchanges show that the idea of delivering equity exposure through crypto infrastructure has moved from a curiosity to a competitive priority. Those firms have far bigger customer bases, deeper liquidity and established brands, so any smaller venue will need to differentiate through product design, settlement terms or execution quality.
Hypercall's growth, in the company's own telling, reflects demand for blockchain access to traditional markets. Whether that demand stays concentrated on one decentralized chain, or flows to the large centralized exchanges that now list similar products, will be a central question for the segment in the months ahead. For now, the exchange has put a measurable figure on the appetite: $640 million in notional volume over a little more than four months, led by a single American stock index.
8. What to watch next
The most immediate development to follow is the public naming of Hypercall's additional market makers, which Sylvestre said should happen over the next few weeks. The identities of the firms involved, and how quickly open interest grows once they begin quoting, will indicate whether the platform can move beyond its current size.
Observers will also look at whether index options remain the dominant product as single-stock contracts gain ground, and how the exchange's cumulative volume compares as larger competitors expand their own offerings. Open interest of about $49 million sets a clear baseline against which future updates can be measured.
