Odaily reported that, according to monitoring by on-chain analyst Ai Yi, Binance contract open interest reached $395 million before SPCX opened. Hyperliquid contract open interest stood at $273 million over the same pre-open period. The figures refer to the scale of outstanding positions in the relevant contract markets and were disclosed in connection with SPCX’s opening.
Kraken IPO subscriptions and Polymarket activity were also reported
The same monitoring update showed that total subscriptions for the Kraken IPO reached $888 million. Of that amount, Binance Wallet accounted for $557 million in subscriptions. The disclosure separated the overall subscription figure from the Binance Wallet portion, showing the size of Binance Wallet’s participation within the reported total.
In addition, trading volume on Polymarket wagers related to SPCX’s closing market capitalization exceeded $13 million. The reported data covered three areas: contract open interest, IPO subscriptions, and prediction-market betting volume. All of the figures were attributed to Ai Yi’s on-chain monitoring disclosure.
