A commit titled “Binary options support” recently appeared in the codebase for the decentralized order book exchange platform Lighter, indicating that its ZK Circuits may have begun supporting binary outcome markets (prediction markets). Based on the code, each market features a settlement cap, with share prices trading between 0 and the cap; upon settlement, shares ultimately resolve to zero or reach the cap. Contracts are fully collateralized with USDC, meaning they involve no leverage or liquidation. Analysis suggests that Lighter may introduce a "market operator" model, which would allow whitelisted operators to create, manage, and handle market settlement, similar to the HIP-3 deployment model.

According to Crypto Pulse Research, Bernstein's September 16, 2026, research report states that the procedural vote on the CLARITY Act has failed, and there should be no hope for a revote. Stablecoins, governed by the GENIUS Act, remain unaffected, while Circle’s ARC chain launched that same day. Robinhood's daily on-chain gross revenue is approximately $1 million. The bank recommends buying the recent weakness in crypto equities, favoring Robinhood (HOOD), Circle (CRCL), and Figure (FIGR), with target prices set at $160, $140, and $70, respectively. It sets a $330 price target for Coinbase, $350 for Strategy, and $24 for Sharplink. Bernstein believes that following legislative failure, regulatory clarity will pivot toward rulemaking by the CFTC and SEC. This rulemaking process will be aggressive and rapid, making product rollout schedules more predictable. Advancement of stablecoins, tokenization, perpetual futures, and prediction market-related products will continue, with crypto stock pullbacks offering buying opportunities.
