Anthropic Finishes Mythos Successor as CME Sues CFTC, $24M World Cup Wallets Flagged

Crypto News

Anthropic has reportedly completed training of a more capable successor to its suspended Mythos 5 model, according to an AI researcher tracking the company. The system, which remains officially unconfirmed, could ship as Mythos 5.1 or Mythos 6 — or stay internal to accelerate development. The report arrived nine days after US export controls forced Anthropic to suspend both Mythos 5 and Fable 5 worldwide. Commerce Secretary Howard Lutnick issued the directive on national-security grounds, barring all foreign nationals — including Anthropic’s own foreign-born staff — from access. Anthropic, which has secured commitments of up to $25 billion from Amazon, says it continues working to reverse the controls.

CME Group has filed suit against the Commodity Futures Trading Commission, asking a federal court to vacate the regulator’s approval of Kalshi’s perpetual futures contracts. The exchange operator argues the CFTC failed to properly weigh the application before granting it, and that perpetual futures — known as perps — are legally swaps under the Dodd-Frank Act rather than futures, a distinction that carries different regulatory requirements. CME claims the agency merely rubber-stamped the application and never addressed the swap definition in its order. The complaint, filed Thursday, also warns that perps threaten its long-dated futures business. The CFTC granted Kalshi’s approval at the end of May.

A viral weekend claim that Anthropic’s Mythos model breached nearly all of the National Security Agency’s classified systems has been disputed by BitGo chief executive Mike Belshe, who called the framing false. The assertion traced back to remarks by Senator Mark Warner, vice chair of the Senate Intelligence Committee, who said the NSA director described a tool that penetrated classified systems in hours rather than weeks. The editor who originally published the quote later cautioned it should not be read literally, noting the result depended on the model operating alongside other tools under specific conditions. Crucially, the exercise was an authorized red-team test on government networks, not an external intrusion.

Three cryptocurrency wallets collectively booked $24.25 million in profit from World Cup prediction markets before routing proceeds to the same Binance deposit address, raising questions over whether one trader controlled all three accounts. On-chain data identified the wallets as mintblade, GRIMDRIP and EndlessFate, which together recorded 13 winning positions across 16 settled bets before halting activity and withdrawing funds. Mintblade alone earned $9.24 million with no recorded loss, while GRIMDRIP and EndlessFate added $7.6 million and $7.41 million respectively. All three funneled gains through the deposit address 0xB08B...317D. Analysts stressed the shared route and trading record alone do not prove misconduct.

The activity underscores how the expanded 48-team World Cup has turned sports prediction markets into a major speculative venue. On-chain and platform data show more than $5 billion traded across World Cup contracts on Polymarket’s international exchange and Kalshi during the tournament’s opening stages. Polymarket’s outright-winner contract alone reached roughly $3 billion in cumulative volume, an all-time high that makes it the platform’s largest market. The scrutiny reflects a broader transparency challenge: whether automated trading bots or human bettors are behind them, pseudonymous accounts can amass outsized positions, and large payouts can stem from analysis, risk tolerance, or simply backing underdogs.

The Anthropic suspension has spilled into a wider political and security debate. The export directive followed a reported warning from Amazon — itself a major Anthropic backer — that its researchers had used Fable 5 to surface attack-ready information. The government separately flagged a method for bypassing Fable 5’s safeguards, which Anthropic reviewed and characterized as narrow, warning the same standard would halt new model launches across the industry. The clash has drawn comment from President Donald Trump and a public defense from chief executive Dario Amodei. Anthropic says roughly 50 partners have used early Mythos models to identify more than 10,000 high- or critical-severity software flaws.

The common thread across these stories is regulatory and security friction colliding with rapid technological and market expansion. COINOTAG’s aggregate market data captures the cautious mood: the Fear and Greed Index sits at 23, in Extreme Fear, while Bitcoin dominance holds at 70.1% and total crypto market capitalization stands near $1.82 trillion. As frontier AI access tightens and exchanges contest how perpetual products are classified, capital is concentrating in established assets and away from speculative altcoins. Prediction-market volumes show retail risk appetite remains intact, but on-chain transparency — not headline profits — will ultimately shape how regulators treat these venues.
