a16z crypto: Prediction Markets Still Need to Overcome Manipulation Risk and Information Bias Challenges

a16z Crypto published an article analyzing the unique value and challenges faced by prediction markets. Prediction markets allow participants to trade on event outcomes, aggregating dispersed information through price signals to provide real-time probability estimates for future events. Unlike traditional polls, prediction markets offer real-time update capabilities and incentivize participants to stake capital on their information, thereby improving prediction accuracy.The article points out that prediction markets are not only used by enterprises for product launches and research experiment forecasts, but also serve as "wisdom of the crowd" information sources for media outlets, covering events ranging from geopolitics to AI model performance. Their core advantage lies in providing independent probability estimates for specific events, rather than relying on indirect signals from overall asset price movements.However, prediction markets still face infrastructure and market design challenges, including event verification, contract settlement, the sufficiency of participant information, and potential manipulation risks. a16z believes that if these issues are resolved, prediction markets could become important tools for decision-making and information aggregation, expanding the ability of finance and society to gain insights into future events.

Swedish prosecutors suspect information leak led to premature exposure of Sivers (SIVE) dual-listing rumors, causing stock price volatility; investigation launched

: Jonas Myrdal, a prosecutor at the Swedish Economic Crime Authority, stated that regarding a post on social platform X about Sivers Semiconductors (SIVE) considering a dual listing in the US leaking out early and being officially confirmed by the company approximately 48 hours later, he believes this is not a coincidence but highly likely involves an information leak.Jonas Myrdal pointed out that the relevant information was published and continuously promoted on platform X by an anonymous account with approximately 200,000 followers before its official disclosure. This subsequently triggered a sharp, several-fold increase in the company's stock price within a short period. This behavior pattern is similar to a previous case involving "pump-and-dump" manipulation, in which three individuals were convicted of serious market manipulation offenses. He further recommended that Nasdaq should investigate this incident and assess whether it violates the EU Market Abuse Regulation (MAR). Currently, the source of the suspected information leak is still under investigation.Previously, "New Stock God" Serenity posted on platform X seemingly "touting" Sivers, and stated that after further reviewing Sivers Semiconductors' latest earnings conference call, they are optimistic about its prospects. The company's management indicated that "in a super-cycle where demand far exceeds supply, viewing ecosystem partners as competitors is not the correct approach," reflecting the current strong demand in the photonics industry. Additionally, the photonics business pipeline has grown rapidly over the past five months, driving an overall revenue pipeline increase of 77%. (Marketscreener)

Grayscale: Hyperliquid Could Evolve into an On-Chain Financial Infrastructure Giant, Challenging the Traditional Derivatives Market

digital asset management firm Grayscale stated in its latest report that the decentralized trading platform Hyperliquid is rapidly evolving from a crypto perpetual contract exchange into a blockchain-based financial infrastructure platform. In the future, it may even challenge the traditional derivatives trading and exchange systems, growing into a "financial services giant."The report shows that Hyperliquid generated approximately $800 million in revenue in 2025, with a full-year perpetual contract trading volume of about $2.9 trillion and open interest of roughly $7 billion, capturing a significant share of the crypto derivatives market. Grayscale believes the platform is no longer limited to crypto trading. Through the HIP-3 and HIP-4 systems, it is expanding into tokenized stocks, commodities, and prediction markets, gradually building a 24/7 on-chain trading infrastructure.In another report, FalconX also pointed out that Hyperliquid is competing with traditional derivatives exchanges like the CME Group, as well as prediction market platforms such as Kalshi and Polymarket, and is making progress in new markets like Pre-IPO.The report also emphasized that regulation remains a key variable. Although Hyperliquid currently restricts access for US users, as the regulatory framework gradually clarifies and institutions like Coinbase, Robinhood, and Kraken explore perpetual contract products, this sector may see broader growth potential in the future.

Bank of America Warns AI Optimism Is Overheated: Markets Are Betting on an “AI Version of the WTO Moment”

BofA believes that current global corporate earnings expectations have clearly outpaced macroeconomic fundamentals, and the market is betting that AI will reshape the global labor market and boost corporate profit margins—much like China’s accession to the WTO did in its time. However, this logic still faces multiple risks related to demand, costs, and policy.

Zama founder: cUSDC freeze incident triggered by Overnight hack funds, cUSDC and other contracts suspended

Odaily Odaily founder Rand posted on platform X, stating that with the assistance of on-chain detective ZachXBT, the team has identified the root cause of the recent cUSDC freeze incident, which is unrelated to the Zama protocol itself or privacy technology. The incident originated when a wallet address associated with the Overnight Finance hack deposited over $12.5 million USDC into Zama's cUSDC wrapper contract. Since the address was not on any sanctions list at the time of deposit and was not flagged by KYT (Know Your Transaction) tools, the funds were able to enter the protocol.Rand stated that law enforcement agencies recently issued asset restriction orders against several wallets linked to the hacker. At that time, the cUSDC wrapper contract held relatively small funds, with over 99% coming from the aforementioned hacker address. Consequently, the court ordered the freezing of the entire wrapper contract to restrict the movement of the related funds. Rand emphasized that this measure is not a sanction against Zama or privacy protocols, but a common judicial freezing measure in the DeFi space.To cooperate with the investigation, Zama has suspended the operation of the cUSDC, cUSDT, and cWETH contracts until the investigation is complete, all involved addresses are identified, and corresponding measures are taken. Rand reiterated that Zama adheres to the principle of "compliant confidentiality" and will not tolerate any illegal activities. He also indicated that a more detailed post-mortem of the incident and a plan for handling similar requests in the future will be released subsequently.

Zama responds to cUSDC contract freeze incident: triggered by a related address's compliance mechanism, not targeted sanctions against the protocol

privacy computing protocol Zama posted on the X platform stating that Circle's compliance system flagged an external deposit address. Because this address held funds in the cUSDC contract, the entire cUSDC contract was included in a routine freeze measure. Zama emphasized that this incident is "collateral damage" caused by the affected address and is not a sanction action targeting the Zama protocol. Currently, Zama's legal team has intervened and is working with relevant parties to isolate the flagged address and restore normal access to funds for other unaffected participants as soon as possible.

Kyle Samani: Kalshi and US Crypto Perpetual Contracts Face Uncertainty with Three Potential Outcomes

Odaily Planet Daily reports: Multicoin Capital co-founder Kyle Samani posted on X platform analyzing three possible scenarios for the development of Kalshi and the US crypto perpetual contract market:1. Kalshi's previous efforts are irrelevant: Because the US market itself can already offer unregulated perpetual contracts.2. Protocols must pass the eight decentralized tests of the CLARITY Act: If the CLARITY Act passes smoothly, protocols can offer perpetual contracts in the US without registering as a DCO (Designated Contract Organizer) and DCM (Designated Contract Market).3. Products can still attract users but cannot legally enter the US financial system: Even with user recognition, protocols may still be unable to distribute within a compliant framework.Analysis suggests that these potential outcomes highlight the complex relationship between current US derivatives regulation and decentralized protocols, as well as the uncertainty surrounding the compliant implementation of innovative financial products.

The U.S. Department of State has designated Brazilian criminal organizations CV and PCC as "Specially Designated Global Terrorists"

the U.S. Department of State announced the designation of two Brazilian organizations, Comando Vermelho (CV) and Primeiro Comando da Capital (PCC), as "Specially Designated Global Terrorists (SDGTs)." They plan to officially designate them as "Foreign Terrorist Organizations (FTOs)" starting June 5, 2026. These organizations have been accused of using digital currencies for money laundering, with PCC reportedly using Bitcoin mining as a cover for laundering funds.Previously, Brazil passed a new law in March of this year allowing confiscated crypto assets to be used for public safety expenditures. This move marks Brazil's shift in viewing crypto assets from a potential reserve tool to law enforcement resources, strengthening efforts to combat crimes by PCC, CV, and other organizations, while advancing the judicial system's capabilities in regulating and disposing of digital assets.

Kalshi Crypto Business Lead: Cryptocurrency Accounts for 70% of Platform Prediction Market Trading Volume

Meanwhile, Kalshi also serves as a liquidity layer for Coinbase and Phantom's frontend, and only accepts cryptocurrency for international deposits.He once again joked at the end: "That's right, Kalshi is not a cryptocurrency company."

In reality, the purported trading bot did not operate as advertised. The SEC charges that Fuller misappropriated at least $6.2 million of investor funds for personal expenses and used approximately $5.5 million from new investors for "Ponzi-like payments," while misleading investors through fake account statements and fictitious institutional communications.The SEC has filed a lawsuit in the U.S. District Court for the Southern District of Texas, accusing Fuller of violating securities offering and anti-fraud laws, and is seeking permanent injunctions, disgorgement of ill-gotten gains, and civil penalties.

Odaily Celsius founder Alex Mashinsky has filed a motion with a New York court, seeking to overturn his 12-year sentence for fraud and market manipulation.Court documents show that Mashinsky chose to proceed pro se after his lawyers withdrew, claiming they 'stopped communicating' with him, forcing him to file documents personally with the court. He argues that his previous defense constituted 'ineffective assistance of counsel' and invokes the 'fruit of the poisonous tree' doctrine, challenging the legality of certain evidence in the case.In his filings, Mashinsky also accused Sam Bankman-Fried of intending to 'destroy Celsius' and attributed market manipulation related to the CEL token to FTX. Additionally, he publicly disclosed text messages with former Celsius Chief Revenue Officer Roni Cohen-Pavon, alleging that Cohen-Pavon attempted a 'hostile takeover' of the company.In 2025, Mashinsky pleaded guilty to commodities fraud and securities fraud, was ordered to forfeit $48 million, and must also pay a $10 million settlement to the U.S. Federal Trade Commission. Cohen-Pavon, who previously testified as a cooperating witness for the prosecution, has been sentenced to 'time served' and ordered to pay over $1 million in fines. (Cointelegraph)

SEC Chairman: Will Promote On-Chain Capital Market Reform and Clarify Boundaries of Digital Asset Securities

U.S. SEC Chairman Paul S. Atkins stated at the 2026 Reagan National Economic Forum that the U.S. Securities and Exchange Commission is advancing a "New Era SEC" regulatory reform, focusing on modernizing digital asset regulation, promoting on-chain capital market development, and supporting the U.S. in becoming a "global crypto hub."Paul Atkins criticized the SEC's previous "regulatory hostility" towards the digital asset industry, alleging that much crypto innovation was forced to relocate overseas. He stated that with the support of the Trump administration, the SEC has launched "Project Crypto" and is collaborating with the Commodity Futures Trading Commission to promote on-chain market infrastructure and harmonize crypto regulation. The SEC has recently clarified which digital assets are securities and which are not, and is advancing an innovative exemption mechanism for "tokenized listed securities," while studying how on-chain trading systems can fit within existing regulatory frameworks.Additionally, Paul Atkins emphasized that the SEC will reduce "over-disclosure" and regulatory burdens, promote "Make IPOs Great Again" reforms, including lowering compliance costs for listed companies, increasing IPO flexibility, and formally proposing to repeal the climate disclosure rules introduced under the previous administration. The future of U.S. capital markets should be built on a "free market and innovation-driven" foundation, where the regulator's role is to provide clear rules and legal certainty, not to suppress technological development.
