Morgan Stanley Investment Management has launched two spot crypto ETPs: the Ethereum product MSSE and the Solana product MSOL. Both are listed on NYSE Arca and carry a 0.14% fee. The firm said each product plans to use part of its ETH and SOL holdings for staking, and that Morgan Stanley Investment Management will not retain the staking rewards. Together with its earlier Bitcoin product, MSBT, the firm’s crypto ETP lineup now covers BTC, ETH and SOL.
Kalshi parlay bets tied to about $294 million in retail losses
Parlay betting on prediction market platform Kalshi has cost bettors about $294 million in cumulative losses. The report said retail users tend to favor low-probability, high-payout multi-leg combinations, where missing any single outcome wipes out the full wager. Professional traders, by contrast, have been profiting by taking the other side.
One example cited in the report said a popular World Cup final combination had an implied probability of just 2.7% at kickoff. Publicly available data does not disclose the precise period used for the loss tally. Recent research also found that Kalshi’s cross-event parlay pricing showed systematic overvaluation relative to the product of individual probabilities, with the premium usually becoming more pronounced as more legs were added.
Study finds 31 unknown vulnerabilities across x402 payment providers
A study released on July 21 found 31 previously unknown vulnerabilities across 15 major x402 payment providers, covering 99% of relevant transactions during the study period. Researchers confirmed two flaws that could enable what they described as “free shopping,” and also identified high-risk paths involving asset theft, denial of service and gas abuse.
The study did not conclude that all x402 payments were vulnerable, nor did it say Coinbase itself was necessarily affected. Coinbase, PayAI and Mogami have confirmed some of the issues and started fixes. The researchers recommended that merchants deliver services only after on-chain settlement has been completed successfully.
Solido Money says 293.7 million SUPRA were stolen in attack
Solido Money said it was hit by an attack that resulted in the theft of about 293.7 million SUPRA. Of that amount, around 220 million SUPRA had already been transferred to suspected Gate deposit addresses. The report added that about 90% of the affected funds belonged to the Solido Foundation.
Solido Money said its forensic report on the incident has been made public and that a protocol fix and recovery plan will be released within the next 72 hours.
Futu and Tiger options front-running case expands to more than 310 accounts
A lawsuit brought by market makers Susquehanna and Citadel Securities now involves more than 310 trading accounts. The plaintiffs are seeking to recover more than $137 million in suspicious options profits. Just eight traders accounted for more than $80 million in gains, or nearly 60% of the estimated total.
The accounts were accused of concentrating purchases of short-dated put options before Chinese regulators moved on May 22 against the cross-border business of Futu and Tiger Brokers. A court has approved asset freezes and ordered brokerages to disclose account information, though participation in the trades does not by itself amount to a legal finding of wrongdoing.
