# Kalshi Shatters Daily Trading Records Amid Regulatory Scrutiny Prediction market Kalshi hits consecutive $5.3 billion volume days despite mounting legal and political pressure. - **Source:** [Bitcoin News](https://brifing.si/source/d8aeaf1e-9839-4dad-9d25-7a6bf3fbeef8) - **Published:** 2026-11-10 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/9f7ed55d-9cdb-4a18-af25-08f9b36aacd0 ## Record-Breaking Weekend Performance Kalshi achieved unprecedented trading activity on November 7 and 8, recording notional volumes of $5.33 billion and $5.36 billion respectively. These figures surpassed the exchange's previous daily record of $5.30 billion set on October 24. This marks the first time the platform has exceeded $5 billion in volume for two consecutive days. ## Dominance of Combo Contracts Parlay-style combo contracts, which bundle multiple outcomes into one, served as the primary driver for these record volumes. These instruments accounted for approximately 75% of total trading activity over the weekend. This represents a significant rebound from Election Day, when combo volume share dropped to 58.6% as single-market interest surged. ## Diverse Asset Class Activity Beyond election-related markets, trading volume was bolstered by bitcoin contracts and football-related bets. On Sunday, bitcoin contracts reached $281.8 million, while NFL game markets and spreads contributed $320.2 million combined. These figures highlight the exchange's growing reliance on cross-category series, which saw one specific series trade $3.92 billion on Saturday. ## Legal Challenges from AGA The American Gaming Association filed an amicus brief in the Second Circuit on November 6, challenging Kalshi's operations. The trade group argued that the exchange's offerings are effectively sports bets, citing complex parlays with up to 453 legs. They contend that these products do not serve a legitimate hedging purpose for traders. ## Regulatory and Age Concerns The AGA brief also raised concerns regarding user demographics, estimating that individuals under 21 had wagered $9.5 billion on the platform as of November 2. Since New York law prohibits sports wagering for those under 21, this discrepancy adds significant legal complexity to Kalshi's ongoing appeal against state-level regulatory restrictions. ## Legislative Pressure in Congress Political scrutiny is intensifying as Congressional leadership shifts. Senator Jeff Merkley has publicly called for legislative action to curb prediction markets following the recent midterm results. Meanwhile, Senators Elizabeth Warren and John Curtis have initiated inquiries into how platforms like Kalshi and Polymarket prevent insider trading within their election-focused market segments. ## Understanding Notional Volume Metrics It is important to note that Kalshi's reported volume reflects notional value rather than actual capital at risk. The metric counts each contract at its full $1 payout potential. This distinction is crucial for interpreting the scale of platform activity, as it differs from the total cash deposits held by traders. ## Future Market Implications The intersection of record-breaking financial growth and heightened regulatory hostility creates an uncertain outlook for prediction markets. As Kalshi faces simultaneous pressure from federal courts and incoming Congressional majorities, the sustainability of its current parlay-heavy business model remains a central point of contention for both industry observers and government regulators. ## Sources covering this story - https://news.bitcoin.com/igaming/kalshi-posts-back-to-back-5-3b-days-topping-its-october-record/ — --- _Summary written by Brifing from the original reporting.
