Kalshi Perps Hit $1B in Days, ProShares Plans 2x SpaceX ETF, Fable 5 Rattles DeFi

Crypto News

Kalshi's perpetual futures crossed $1 billion in cumulative trading volume in under a week, a pace that dwarfs the firm's original prediction-market business. The company's Bitcoin perpetual contract, BTCPERP, went live on June 3 and generated more than $100 million in its first 24 hours. By comparison, Kalshi's event contracts needed roughly 40 months to reach the same $1 billion threshold. The figures are notional and include leverage, yet the contrast underscores how quickly demand for regulated Bitcoin derivatives can scale once US traders gain compliant access to a product previously confined to offshore venues.

The launch followed a landmark regulatory shift. On May 29, the CFTC cleared both Kalshi and Coinbase to offer perpetual futures, making them the first US companies authorized to list these contracts domestically. Coinbase secured its approval through an affiliate tied to Deribit, the options platform it acquired for $2.9 billion. Until that ruling, American traders seeking perpetuals had to route orders through offshore exchanges such as Binance or Bybit, absorbing both counterparty and legal exposure. Perpetual futures represent roughly $90 trillion in annual global volume, the single largest segment of crypto derivatives, and onshore access reshapes how that liquidity is captured.

Leveraged-product issuer ProShares plans to launch its Ultra SpaceX ETF, ticker SPCF, on June 12, targeting twice the daily return of SpaceX shares. The firm, which manages more than $90 billion across over 115 funds, positions the product alongside existing single-stock leveraged vehicles tracking Circle, Coinbase, NVIDIA, Palantir and Tesla. Chief executive Michael Sapir said the fund lets traders amplify a bullish view on SpaceX without borrowing on margin during the debut session. The timing is deliberate: the ETF is designed to begin trading the same day SpaceX makes its public-market debut, an unusually aggressive move for a same-day leveraged launch.

Demand for the SpaceX offering has been extraordinary. Order books have attracted more than $250 billion in bids against a $75 billion target, leaving the deal oversubscribed by roughly 3.5 to 4 times. The sale now ranks as the largest initial public offering on record by capital raised. The timeline is compressed: books close on Wednesday, pricing follows on June 11, and shares are slated to begin trading on the Nasdaq on June 12. The scale of interest signals strong institutional conviction ahead of the listing and helps explain why issuers are racing to wrap leveraged products around the stock from day one.

AI developer Anthropic released the first public version of its Claude Mythos system, branded Fable 5, drawing scrutiny from blockchain security researchers. The company previously disclosed that the underlying model identified more than 10,000 high- or critical-severity vulnerabilities in widely used software, raising questions about whether such a capable tool should ship publicly. Anthropic said Fable 5 was made safe for general use, with safeguards that reroute sensitive requests, including cybersecurity queries, to a separate model. Even so, the firm acknowledged that without guardrails the system's offensive capabilities could be misused to cause serious damage, a caveat that did little to calm crypto practitioners.

The release reignited security concerns across DeFi. Moonrock Capital founder Simon Dedic warned that the cost and skill required to find exploitable flaws in smart contracts could fall to near zero, leaving unaudited protocols as sitting ducks and exposing forks of decentralized exchanges and automated market makers to replayed exploits. He urged users to revoke wallet approvals, withdraw funds and move holdings to fresh cold wallets. Curve Finance co-founder Michael Egorov countered that the threat is likely overblown, arguing that bug-hunting success in conventional software may not translate to smart-contract exploitation. Crypto hacks reached $629.7 million in April, the highest monthly total since February 2025.

Taken together, these developments trace a single arc: traditional finance and crypto rails are converging at speed, even as the security perimeter strains to keep pace. Regulated perpetuals, same-day leveraged ETFs and frontier AI all compress timelines that once spanned years. COINOTAG's aggregate market data frames the backdrop sharply, with the Fear and Greed Index sitting at 9 out of 100, deep in Extreme Fear, while Bitcoin dominance holds at 70.2% and total crypto market capitalization stands near $1.75 trillion. That mix of risk-off sentiment and concentrated capital suggests participants are consolidating into established assets while institutional infrastructure expands around them. The official CFTC approvals and company disclosures behind these moves remain the primary record.
