SpaceX-linked perpetual futures generated about $6 billion in turnover across Binance and Hyperliquid following the company’s October 20 earnings release, according to market-data provider Talos and reporting from CryptoSlate. The activity was more than eight times the previous day’s volume, highlighting how quickly derivatives markets can attract trading around major corporate announcements.
The surge in turnover came alongside a decline in Binance’s open interest. Talos reported that the exchange’s outstanding dollar exposure in SpaceX’s SPCX perpetual fell by roughly 8% after the earnings event. The contrasting figures do not necessarily conflict: turnover measures contracts traded during a period, while open interest measures positions that remain open afterward.
Trading jumped as open positions declined
SpaceX’s third-quarter results release scheduled its earnings call for 4:30 p.m. Eastern on October 20. Talos said the SPCX perpetual on Binance rose 8.5% between the earnings release and the following U.S. market open.
Its estimate of roughly $6 billion covers turnover on both Binance and Hyperliquid during the post-earnings episode. The open-interest figure, however, applies only to Binance. The measures also use different venue coverage and time windows, so they should not be treated as a direct comparison of the same pool of positions.
The distinction is important in a derivatives market. Volume records executions, including trades that open or close positions. Open interest records contracts still outstanding, with each buyer-and-seller pair counted once. For example, if an existing long sells to an existing short that is buying back to close, the transaction increases volume while both positions disappear, reducing open interest.
As a result, a market can be exceptionally busy while ending with less exposure left open. The reported figures indicate intense post-earnings trading, but they do not establish how much of the turnover represented new positions, closing trades or changes in direction.
What the contracts represent and how fees are set
SPCX perpetuals are derivatives that reference the price of one SpaceX Class A share quoted in dollars. The current specification from market operator trade[XYZ] allows cross-margining and maximum leverage of 20 times. Unlike a conventional futures contract, a perpetual has no scheduled expiry; funding payments are used to help keep its price aligned with the underlying reference.
The notional value traded in these contracts is therefore different from purchases of SpaceX shares. It represents the value of derivative transactions rather than ownership of the underlying stock.
Margin requirements can also affect how much exposure traders can maintain. Hyperliquid’s initial-margin formula uses position size, mark price and leverage, while shared collateral and unrealized profits can affect the margin available for other positions.
The reported turnover cannot be converted directly into a precise fee figure. Costs vary according to the venue, a trader’s maker or taker status, rolling 14-day volume, staking discounts, referrals and the specific market settings. Eligible makers may receive rebates, meaning two traders can generate different net fees on the same amount of turnover.
The trade[XYZ] schedule illustrates the range. Its tier-zero standard taker rate is 0.09%, compared with 0.009% under its growth-mode schedule. The corresponding maker rates are 0.03% and 0.003%. Hyperliquid says growth mode, where available for an eligible HIP-3 market, reduces fees, rebates and volume contributions by at least 90%, although other discounts can also affect the result. The historical setting for SPCX and the mix of trader tiers and rebates on October 20 and 21 were not verified in the report.
Where platform fees can go
Hyperliquid’s HIP-3 framework lets market deployers define contract terms and oracles, set leverage limits and settle markets while using HyperCore’s order books and margin infrastructure. Those choices influence how trading activity translates into revenue for the operator and protocol.
The distribution of fees also varies. trade[XYZ] describes its standard fees as being split equally between Hyperliquid and the operator, while other HIP-3 markets can use different arrangements. Hyperliquid’s documentation says HIP-3 deployers may retain up to half of the trading fees generated by their assets.
A separate channel involves Hyperliquid’s assistance fund. Fees received by the fund are automatically converted into HYPE, and the purchased tokens are burned. That means the amount relevant to this mechanism is the fund’s own receipts and conversions—not the full turnover, total gross fees or the operator’s share.
Because the reported $6 billion combines Binance and Hyperliquid activity, and because the effective rates and fee allocations are not fully established, the event’s actual retained fees remain unquantified.
