Kalshi Blocks 100+ Insider Trades, Backpack Adds Ex-SEC Chair, SBI Pays Crypto Interest

Crypto News

Prediction market operator Kalshi rolled out three market integrity measures effective immediately, introducing a risk-scoring system, employment verification for high-risk markets, and expanded whistleblower tools that route tips to a round-the-clock surveillance team. Every proposed market now receives a risk score weighing six factors, including corporate KPI exposure, outcome concentration, and national security relevance. Markets flagged as high-risk require participants to submit employment information, screening out presumptive insiders before any trade executes. The platform disclosed that its tools blocked more than 100 suspected insider trades in the first quarter, alongside 150-plus investigations, 20-plus referrals to authorities, and five disciplinary actions, a tightening that also pressures rival decentralized platforms running on a DEX(分散型取引所)とは?完全ガイド model.

Japan's financial regulator confirmed it has received five consultations citing losses tied to SANAE TOKEN, a digital asset bearing the prime minister's name, with three claimants asserting specific damages and one filed by a non-resident. The disclosure came during parliamentary questioning over how authorities track unregistered operators. Lawmakers noted the token surged roughly thirtyfold on its debut, reaching a scale near 2.5 billion yen. A pending legal amendment would presume contracts from unregistered crypto sellers void under public-order provisions, shifting the burden of proof onto operators, while raising the maximum prison term from three to ten years and bringing such activity under compulsory investigation by securities watchdogs.

Crypto exchange Backpack US appointed former acting SEC Chairman Michael S. Piwowar to its board, deepening a regulatory bench that already includes ex-CFTC acting chair Mark Wetjen as president. The move follows the CFTC's approval of Kalshi's ビットコイン(BTC)とは?完全ガイド perpetual futures contract, the first such product cleared on a US regulated venue and a path for derivatives long confined offshore. Backpack already runs regulated perpetuals in the EU and plans to extend the lineup stateside. Separately, the firm launched a public beta of Backpack Securities, a single-account platform for tokenized US equities, ETFs, crypto, and perpetuals settled through New York-law securities entitlements.

SBI Shinsei Bank is preparing to reward depositors with crypto, planning an autumn rollout that issues vouchers worth roughly 20% of interest payments redeemable for Bitcoin, Ethereum, or XRP, according to reporting on the bank's plans. Fiat interest would continue to accrue alongside the digital-asset perk. Redemptions route through an SBI VC Trade account, which customers must open in advance, and the program spans three-month to five-year time deposits and ordinary accounts covering roughly 4.33 million individual customers. The initiative extends an SBI Group push that earlier this year launched a credit card accruing the same three tokens via partnerships with Visa and Aplus.

Tokyo-listed Allied Architects and Ethereum-focused research body Nyx Foundation began a proof-of-concept applying AI agents to stress-test the security resilience of DeFi(分散型金融)とは?完全ガイド protocols. The trial pairs an AI bug-discovery system called SPECA with formal-verification agents, assessing not only smart-contract logic but operations, configuration, and governance. The partners note recent large-scale exploits stemmed not from code defects alone but from operational and human-judgment risks. Each check is logged in JSON for third-party verification, and suspected vulnerabilities are confirmed with proof-of-concept exploit code, with human review required on all AI output, as the teams work to standardize a reproducible auditing methodology for ブロックチェーンとは?完全ガイド-based systems.

Binance Research published first-week data from the exchange's new equities-trading service, showing users allocated capital along clear thematic lines rather than at random. Information-technology names drew the largest share at 57% of total inflows, with semiconductors and hardware alone accounting for about 44%, which the firm read as strong conviction in AI-infrastructure investment. Funds and ETPs took roughly 20%, telecom about 11%, and financials around 9%. Notably, around 84% of first-week volume originated from emerging markets, a ratio the firm called structural rather than a passing boom, crediting stablecoin rails that bypass FX costs. The service spans over 7,000 US-listed stocks and ETFs from a single account.

Taken together, these developments trace a single arc: crypto's machinery is fusing with traditional finance even as regulators and platforms race to harden market integrity. Yet COINOTAG's aggregate market data frames the backdrop with caution — our Fear & Greed Index sits at 9, deep in extreme fear, while Bitcoin dominance has climbed to 70.2% and total market capitalization has compressed to roughly $1.75 trillion, signaling capital rotating into ビットコイン(BTC)とは?完全ガイド and out of risk during a defensive 弱気相場(ベアマーケット)とは?完全ガイド phase. Primary-source signals reinforce the divergence: the CFTC's official approval of regulated Bitcoin perpetuals and Kalshi's own surveillance disclosures show infrastructure maturing precisely as on-chain sentiment turns guarded.
