6 Polymarket traders net $1M on US-Iran strike, insider fears: Report

Published

on

Crypto Breaking News

Six Polymarket traders earned roughly $1 million after accurately predicting that the United States would strike Iran before February ended, triggering insider trading concerns on the platform. The six wallets all appeared in February and placed the bulk of their activity on contracts forecasting the timing of a potential U.S. attack, a pattern highlighted by data analytics firm Bubblemaps SA and reported by Bloomberg. In several instances, these bets were opened just hours before explosions were first reported in Tehran, with some contracts purchased for around $0.10 per unit.

On-chain investigators have begun to flag the clustering of new wallets and the rapid-fire timing as reminiscent of insider activity observed in other prediction-market episodes. While such activity is not proof of wrongdoing, it has intensified scrutiny of how information flows can influence decisions on platforms like Polymarket. Attempts to obtain comment from Polymarket prior to publication were not successful.

During the broader escalation, more than $529 million flowed into Polymarket’s strike-related contracts, underscoring the platform’s role as a liquidity vector during geopolitical spikes. The February 28 contract drew roughly $90 million in trading volume, making it the most active date among traders, while an earlier January 31 scenario accounted for roughly $42 million.

It’s important to note that one flagged account had previously lost money on an earlier prediction before placing a larger wager that later yielded more than $170,000, illustrating that a single pattern does not conclusively indicate manipulation. Washington had signaled possible military action for weeks, a backdrop that likely contributed to speculative activity on the platform.

Beyond the Iran-focused bets, Polymarket has faced regulatory scrutiny across multiple jurisdictions. Authorities in the Netherlands, Hungary, Belgium, France, Italy, Romania, Poland, Singapore, and Portugal have moved to block or ban the platform, classifying its event-based contracts as unlicensed online gambling rather than financial trading. The evolving regulatory environment adds a layer of uncertainty for users seeking to trade events tied to real-world outcomes.

The broader insider-trading conversation around Polymarket is not limited to Iran. This week, a cluster of crypto wallets earned more than $1.2 million betting on a contract tied to an on-chain investigation into the Axiom DeFi project, following claims by ZachXBT that an Axiom employee and associates had engaged in insider trading since early 2025. Earlier coverage highlighted a separate Polymarket bet linked to the capture of Venezuelan President Nicolás Maduro, where a single wallet reportedly netted about $400,000 after placing bets moments before the news broke. These examples collectively illustrate the tension between market-discovery dynamics and the potential for information asymmetry to influence outcomes on prediction markets.

As the sector contends with these episodes, lawmakers are not standing still. A bill proposed by U.S. Representative Ritchie Torres, the Public Integrity in Financial Prediction Markets Act of 2026, aims to curb insider trading on prediction platforms by restricting trading for officials or other individuals who possess nonpublic information related to government policy or political outcomes. The proposal underscores a broader push to align digital prediction markets with traditional securities and gambling regulations, a topic that has gained attention amid a wave of enforcement and licensing actions around the world.

Polymarket Iran strike bets draw $529 million in volume

During the height of the Iran-related escalation, Polymarket saw more than $529 million in flow across its strike contracts. The most active line was the February 28 event, which attracted about $90 million in trading activity, indicating a strong appetite for event-driven bets during periods of geopolitical risk. A separate late-January scenario still drew tens of millions in volume, demonstrating sustained interest in predicting real-world outcomes as tensions evolved.

While observers caution that correlation does not equal causation, the clustering of new wallets around sensitive geopolitical bets raises questions about how nonpublic information and timing can influence on-chain markets. Investigators have stressed that the existence of a profitable trade in itself is not sufficient evidence of illicit activity; however, patterns that mimic prior insider-trading signals merit careful examination by platform operators and regulators alike.

The Merits and Limits of Prediction Markets

Polymarket’s experience occurs within a broader ecosystem of event-based markets that promise rapid, real-time pricing of outcomes ranging from geopolitics to sports. Critics argue that the very design—where users can trade on ever-narrow event windows—makes these platforms susceptible to information advantage and potential manipulation. Proponents counter that prediction markets can aggregate dispersed information and provide useful signals for participants. The tension between innovation and oversight remains a defining dilemma for the crypto-driven prediction space.

The ongoing regulatory dragnet adds layers of complexity. As Polymarket has faced bans in multiple jurisdictions, users and developers alike are watching how licensing regimes will evolve. The enforcement posture in Europe, North America, and parts of Asia will likely influence the pace at which such markets expand or contract, depending on how regulators classify event-based contracts and whether they require traditional financial-license frameworks, gambling licenses, or a hybrid approach.

Meanwhile, the ecosystem continues to document and debate incidents of suspected insider activity. The cases tied to Axiom and Maduro, alongside the Iran-related bets, are shaping a narrative about information flow, anonymity, and risk management in on-chain markets. For participants, this translates into heightened due diligence, stricter privacy controls, and more rigorous withdrawal and settlement procedures as platforms navigate evolving compliance requirements.

The Iran episode also prompts a closer look at the broader market consequences. Liquidity surges around high-stakes news events can amplify price discovery but may also increase the risk of mispricing if information leaks influence trading behavior ahead of public disclosures. In this context, regulators and platform operators face the challenge of balancing transparency, user protection, and the fundamental promise of decentralized event markets to reflect real-world developments in near real time.

As the sector moves forward, market participants should monitor regulatory developments, platform policy changes, and ongoing investigative efforts that could shape how prediction markets operate in the coming months. The core takeaway is not merely about a single trade but about how a burgeoning asset class negotiates governance, legality, and the integrity of information in a rapidly evolving financial landscape.

Why it matters

The episode highlights the rising prominence of prediction markets within the crypto ecosystem and the ongoing debates about their governance and legitimacy. For traders, the events emphasize the dual nature of these platforms: they can surface timely information and provide hedging opportunities, yet they also expose participants to regulatory risk and the potential for nonpublic information to influence outcomes. For platform operators, the incidents underscore the need to implement robust identity and telemetry controls, transparent policy guidelines, and clear responses to investigations and licensing inquiries.

From a policy perspective, the convergence of digital markets and geopolitical risk invites a rethinking of how prediction markets should be regulated. The proposed Public Integrity in Financial Prediction Markets Act signals a willingness among some lawmakers to extend traditional oversight concepts into the crypto space, seeking to curb unfair trading practices while preserving the mechanism’s information-rich pricing signal. Regulators will weigh how to balance consumer protection with innovation, a difficult but essential task as markets continue to evolve.

For builders and researchers, the episodes underscore the importance of on-chain analytics in monitoring activity, identifying suspicious patterns, and improving risk controls without stifling innovation. The dialogue between auditors, policymakers, and platform operators will shape the design space for next-generation prediction markets, potentially driving smarter wallet onboarding, better market design, and more robust dispute resolution mechanisms.

What to watch next

  • Regulatory responses to Polymarket and other prediction markets, including potential licensing requirements and enforcement actions.
  • Official statements from Polymarket regarding the insider-trading allegations and steps to strengthen market integrity.

11 Senators Press DOJ and Treasury to Probe Binance Over $1.7B Iran-Linked Transactions

Published

on

Nexo Partners with Bakkt for US Crypto Exchange and Yield Programs

TLDR:

  • Eleven Democratic senators urged DOJ and Treasury to investigate Binance over alleged Iran sanctions violations in 2026.
  • Binance compliance staff reportedly uncovered $1.7 billion in digital assets flowing to Iranian-linked terror entities.
  • Senators raised concerns that Binance may have retaliated against compliance staff who flagged the Iran-linked transactions.
  • Democratic senators flagged Binance’s ties to Trump’s USD1 stablecoin as a potential conflict in any federal enforcement review.

Democratic senators are calling on federal authorities to investigate Binance over potential Iran sanctions breaches.

On February 27, 2026, eleven members of the Senate Banking Committee sent a formal letter to Treasury Secretary Scott Bessent and Attorney General Pam Bondi.

The lawmakers cited recent reports of alleged illicit financial activity on the exchange. They warned that national security could be at risk if Binance is once again flouting U.S. sanctions law.

Senators Cite Evidence of $1.7 Billion Flowing to Iranian Entities

The letter detailed troubling findings uncovered by Binance’s own compliance personnel last year. According to the senators, staff discovered that $1.7 billion in digital assets had flowed to Iranian-linked entities.

Those entities reportedly include the Iran-backed Houthis and the Islamic Revolutionary Guard Corps. In one instance, a Binance vendor allegedly directed $1.2 billion in funds toward Iran-linked accounts.

The senators opened their letter with a direct call to action. “We urge you to conduct a prompt, comprehensive review of sanctions compliance on the platform to ensure that it is not once again violating the law and threatening U.S. national security,” they wrote.

The senators also noted that Iranians had reportedly accessed more than 1,500 accounts on the platform. There were further indications the exchange may have been used to help Russia evade U.S. sanctions as well.

These findings led the Democratic senators to question whether Binance is honoring the terms of its 2023 settlement.

That agreement followed Binance’s guilty plea on charges that included money laundering and sanctions violations.

Making matters worse, Binance reportedly fired the compliance staff who uncovered the Iranian transactions. The senators called this a potential act of retaliation against employees performing their duties.

The Democratic senators argued that these developments point to a broad breakdown in compliance at Binance. Under its 2023 agreements, Binance committed to controls that would “enable it to clearly and effectively identify and interdict transactions and activity that may be prohibited by OFAC.”

Senators said the alleged $1.7 billion in illicit flows suggests those controls are not functioning. Law enforcement sources also reportedly said Binance has grown less cooperative with information requests.

Democratic Senators Flag Trump Family Ties as Conflict of Interest

Beyond the sanctions concerns, the Democratic senators raised a separate but related issue. They pointed to deepening financial ties between Binance and President Trump’s family as a potential conflict.

The exchange has repeatedly promoted USD1, the stablecoin launched by the Trump family’s World Liberty Financial. Binance also helped develop the technology behind USD1 and accepted a $2 billion investment in the token.

The senators were direct in addressing those ties. “We recognize, of course, that Binance has made numerous business decisions that have helped President Trump and his family profit from their crypto ventures,” they wrote.

They also referenced Trump’s pardon of Changpeng Zhao, Binance’s founder and former chief executive. Zhao had pleaded guilty to failing to establish an effective anti-money laundering program before receiving the presidential pardon.

The senators stressed that the stakes extend beyond politics. “If Binance has begun to ignore its illicit finance obligations, the risks are grave and nonpartisan,” they stated in the letter.

Ranking Member Elizabeth Warren led the effort alongside ten Democratic colleagues on the Banking Committee. The group set a deadline of March 13, 2026, for a formal response outlining steps taken to address their concerns.

Ethereum’s Biggest Wallet Upgrade May Be Near, Says Vitalik

Published

on

Vitalik Buterin Gives Shocking Prediction Markets Warning

Ethereum co-founder Vitalik Buterin said a long-discussed plan to make the blockchain network’s accounts more flexible may finally be close to implementation.

On February 28, Buterin outlined a design built around account abstraction that could become possible with the network’s Hegota fork.

How EIP-8141 Could Make Ethereum Wallets More Flexible

Buterin described EIP-8141 as the proposal’s centerpiece, an omnibus design that addresses the remaining challenges of account abstraction.

The goal is to transform wallets into programmable accounts that can batch actions, change signature schemes, and support multisig controls. This shift also enables the separation of transaction authorization from the underlying gas payment.

Most Ethereum users today rely on externally owned accounts (EOAs), which they control with private keys and typically fund with ETH to pay gas fees.

Under Buterin’s proposed design, transactions would be organized as “Frame Transactions.”

This is a structure that breaks activity into a series of calls that can validate a sender, authorize a gas payer, and execute one or more actions.

“The concept, ‘Frame Transactions’, is about as simple as you can get while still being highly general purpose. A transaction is N calls, which can read each other’s calldata, and which have the ability to authorize a sender and authorize a gas payer. At the protocol layer, that’s it,” he explained.

In practical terms, a transaction could include separate frames for validation and execution. For more complex flows, a deployment frame could be added for accounts that do not yet exist on-chain.

It also means that batch operations, such as approving and then spending a token in a single atomic sequence, could become easier to execute as a first-class transaction type.

Buterin highlighted the role of “paymaster” contracts, which could allow users to pay transaction fees in assets other than ETH. These contracts would also enable applications to sponsor those user fees directly.

In one example, he described a paymaster that could accept RAI, provide ETH for gas in real time, and refund unused value at the end of the transaction.

He argued that the approach would preserve the functionality of existing sponsored transaction systems while reducing reliance on intermediaries.

“Intermediary minimization is a core principle of non-ugly cypherpunk ethereum: maximize what you can do even if all the world’s infrastructure except the ethereum chain itself goes down,” he explained.

Meanwhile, the proposal also has implications for privacy tools on the blockchain network.

Buterin said paymasters could be designed to verify zero-knowledge proofs and pay gas if those proofs are valid.

He also pointed to “2D nonces” as a way for an individual account to receive transactions in parallel from many users. This could potentially improve how privacy-preserving systems operate.

However, Buterin noted that the design’s primary challenge may lie in the mempool—where transactions propagate before entering a block—rather than at the blockchain level itself.

According to him, some highly complex validation logic may be unsafe to broadcast widely. This means that the initial mempool rules would likely need to be conservative before expanding over time.

He added that account abstraction would complement FOCIL, a separate proposal aimed at improving inclusion guarantees for transactions.

Buterin pointed out that developers are also discussing compatibility for existing accounts to ensure they can eventually access the new framework.

This inclusion would enable traditional wallets to benefit from advanced features such as batch operations and gas sponsorship.

Hyperliquid Emerges Winner Amid US Iran Geopolitcal Tensions

Published

on

Hyperliquid's HIP-3 Platform's Open Interest.

Hyperliquid emerged as a rare winner amid the sudden escalation of military hostilities in the Middle East between the US, Israel, and Iran.

This weekend, the exchange saw a surge in commodities-focused derivatives trading, with open interest for these assets reaching an all-time high of more than $1.1 billion.

Hyperliquid Rallies 13% as US and Iran Tensions Roil Markets

The uptrend can be attributed to traders seeking to hedge geopolitical risks while traditional financial markets were closed for the weekend.

As a result, market participants pivoted to the blockchain-based platform to trade synthetic perpetual futures contracts tied to oil, gold, silver, and US equities.

This continuous trading was facilitated by HyperLiquid Improvement Proposal 3, or HIP-3, an upgrade implemented last year.

HIP-3 allows developers to deploy permissionless perpetual futures markets for any asset with a reliable public price feed, provided the creator stakes 500,000 of the platform’s native HYPE tokens.

Driven by the weekend volatility, HIP-3’s open interest eclipsed its previous record of $1.06 billion.

Overall, the broader Hyperliquid platform has accumulated nearly $5.5 billion in total open interest, securing an estimated $1.06 million in protocol earnings over a 24-hour period, according to data from DeFiLlama.

Additionally, data provider Messari reported that HIP-3 markets have generated $4.4 billion in weekend trading volume in February alone.

The platform’s ability to capture traditional market volume drew the attention of prominent industry figures. Arthur Hayes, co-founder of the crypto exchange BitMEX, highlighted the structural shift on the social media platform X.

“Where price discovery happens when TradExchanges sleep…It’s the weekend, [stuff’s] going down, TradExchanges are closed, but Hyperliquid is open for business,” Hayes wrote.

However, the platform’s lack of compliance guardrails could introduce substantial legal hurdles in the future.

Offering synthetic US equities to retail investors without “know your customer” (KYC) protocols or a registered broker-dealer license poses significant regulatory risks.

These practices could draw future scrutiny from the Securities and Exchange Commission and the Commodity Futures Trading Commission

Despite this looming threat, the platform’s native token responded positively to the weekend influx.

BeInCrypto data show that HYPE’s price rose 13% over the last 24 hours, trading above $30 as of press time. Notably, this makes it the best-performing asset among the top 20 cryptocurrencies by market capitalization.

Tokenized Gold Dominates Weekend Price Discovery as CME Futures Close

Tokenized Gold Dominates Weekend Price Discovery as CME Futures Close

Gold pricing shifts onto blockchain networks once US futures markets close for the weekend, according to Iggy Ioppe, former chief investment officer at Credit Suisse and now chief investment officer (CIO) at liquidity infrastructure firm Theo.

CME gold futures stop trading at 5:00 pm ET on Friday and reopen at 6:00 pm ET on Sunday. During that interval, regulated futures markets are inactive and most remaining activity occurs through private over-the-counter deals in Asia that are not publicly reported. As a result, tokenized gold assets such as PAX Gold (PAXG) and Tether Gold (XAUt) become the only continuously available trading venues.

“In terms of publicly visible price formation, onchain markets are responsible for virtually 100% of weekend price discovery,” Ioppe told Cointelegraph.

He added that when futures trading resumes, prices often align with movements that already occurred on blockchain markets. “We are seeing weekend moves reflected when CME reopens,” he said.

Tokenized gold market cap jumps to $4.4 billion

The shift comes amid rising trading volume for tokenized gold. As Cointelegraph reported, tokenized gold expanded rapidly over the past year, adding nearly $2.8 billion in value and growing from about $1.6 billion to $4.4 billion in market capitalization.

The sector’s market cap rose 177%, far outpacing the broader gold market and most major spot gold ETFs, while the number of holders nearly tripled with more than 115,000 new wallets. The growth represented roughly a quarter of all net inflows into the real-world asset (RWA) sector and exceeded the combined expansion of tokenized stocks, corporate bonds and non-US Treasurys.

Trading activity also surged, with tokenized gold recording about $178 billion in 2025 volume and peaking above $126 billion in the fourth quarter. That level would make it the second-largest gold investment product globally by trading volume after SPDR Gold Shares.

Ioppe said that market makers and cross-venue liquidity providers dominate participation, arbitraging price differences between digital and traditional markets. Crypto-native macro traders also play a major role, using tokenized gold not only for exposure to bullion prices but also for collateral, hedging and yield strategies during periods of geopolitical or macroeconomic uncertainty.

“Some institutions are monitoring weekend onchain gold markets, particularly macro and cross-asset desks that track gap risk ahead of the CME reopen,” he said, noting that most institutions treat the signal as informational rather than a basis for active positioning.

24/7 tokenized gold trading lets investors manage risk

Tokenized gold markets allow for continuous trading, which offers a practical risk management advantage. If a geopolitical event occurs while futures markets are closed, traditional participants cannot adjust positions. Tokenized markets allow immediate rebalancing.

On Saturday, tokenized gold rallied as geopolitical tensions escalated following US and Israeli strikes on Iran, with investors moving into XAUT and PAXG while Bitcoin (BTC) and Ether (ETH) fell. XAUT briefly climbed above $5,450 and PAXG neared $5,536 during the day before trimming gains, according to data from CoinMarketCap.

However, Ioppe said adoption still faces obstacles. Liquidity remains smaller than in futures or exchange-traded funds (ETFs), making large trades harder to execute without moving prices. “Regulatory clarity is improving, but fragmentation across jurisdictions slows institutional deployment. Custody, accounting, and capital rules still vary widely,” he said.

For now, tokenized gold is expected to operate alongside traditional products rather than replace them. “The most likely near-term evolution is that of tokenized and traditional markets existing in parallel, each serving a different function,” Ioppe concluded.
