Polymarket Faces Global Blockades as Spain Joins Crackdown on Prediction Markets
Spain joined the growing list of countries taking action against prediction markets, launching disciplinary proceedings against Polymarket and Kalshi.
Authorities said the restrictions will remain in place while investigations continue over the next 3–4 months. Regulators also raised concerns around missing safeguards, including identity verification, protections for minors, and self-exclusion systems for problem gamblers.
The move adds to growing global scrutiny of prediction markets, following similar restrictions in Indonesia, India, Taiwan, Thailand, China, Japan, Belgium, France, Germany, UK, and Ukraine.
Despite the regulatory pressure, the sector continues to see massive activity. Over the past 30 days, Kalshi processed around $5.9B in volume, while Polymarket handled roughly $3.8B, together accounting for nearly 88% of prediction market trading volume.

Spain’s gambling regulator ordered internet service providers to block access to both platforms, arguing they were offering unlicensed betting products tied to future events without authorization under Spanish gambling law.

OpenSea Builds the App Store for AI Agents With ERC-8257
OpenSea has proposed ERC-8257, a new Ethereum standard that creates an open, onchain registry where anyone can publish tools with declared access rules and pricing, allowing AI agents to autonomously discover, evaluate, and use those tools.

OpenSea has proposed ERC-8257, a new Ethereum standard that creates an open, onchain registry where anyone can publish tools with declared access rules and pricing, allowing AI agents to autonomously discover, evaluate, and use those tools.
The core mechanism is simple but powerful: tool publishers register their capabilities onchain with structured metadata: what the tool does, what it costs, and who can access it. Agents query the registry, find the tools they need, pay the declared price, and execute — all without manual integration or API key management.

Meet Dropee. The AI Mini-App Ecosystem Inside Telegram
Dropee is building an AI-powered mini-app ecosystem inside Telegram, centered on Dropee Create – a no-code platform to generate, launch, and monetize apps directly in Telegram. It combines AI app creation with built-in distribution across Telegram’s user network.
Unlike traditional AI app builders that compete for external traffic, Dropee apps launch natively within Telegram’s ecosystem. This removes reliance on app stores and external acquisition channels, giving creators direct access to Telegram’s social and viral mechanics from day one.
The broader DROPEE thesis ties into the AI + revenue narrative outperforming across public and private markets. Some compare the category expansion to platforms like Lovable, which recently reached a multi-billion valuation after rapid adoption in AI applications.

Google Engineer Charged Over $1.2M Insider Trades on Polymarket
US prosecutors have charged a Google software engineer, Michele Spagnuolo, with allegedly using confidential internal search data to place trades on Polymarket and earn around $1.2M in profit.
Authorities say he made at least 20+ trades linked to Google search trend outcomes, wagering millions of dollars and benefiting from information that had not yet been publicly released. The trades reportedly generated over $1.2M in gains once the official Google data was published.
The U.S. Department of Justice has charged him with commodities fraud, wire fraud, and money laundering, while the CFTC filed a parallel civil case. If convicted, he faces decades in prison.

THORChain Hit by $10.7M Exploit. 5 of 6 Vaults Survived
This attack was carefully prepared over weeks, not executed overnight. Chainalysis traced the attacker’s setup back to late April, when a linked wallet moved XMR through a privacy bridge, swapped into USDC, bridged to Ethereum, and bonded RUNE on THORChain to operate as a legitimate validator before executing the exploit.
THORChain detected abnormal balances within minutes and halted the network through validator coordination and emergency governance actions, without any central authority. Only 1 of 6 Asgard vaults was breached: $10.7M was drained, while the remaining vaults, LP positions, and user funds were unaffected.

The attack targeted THORChain’s GG20 threshold signature scheme, where validators jointly sign transactions using split key shares. By exploiting a flaw in the implementation, the attacker gradually extracted enough key material to reconstruct private key and bypass signing process.
