The Gambling Wire: Prediction Markets Surge Past $9.4 Billion as Sports Betting Expands Into Nebraska

Overview: A Week of Record Volume, Regulatory Battles, and Market Shifts

The gambling and prediction market industry experienced a whirlwind week, marked by staggering trading volumes, aggressive political lobbying, legal showdowns, and fresh academic insights into market behavior and public health consequences. From DraftKings and FanDuel pouring millions into Nebraska’s online sports betting campaign to Polymarket fighting Dutch regulators in court, the landscape is evolving rapidly. Below, we break down the key developments, provide context, and explore what they mean for investors, policymakers, and the public.

H2: Prediction Markets Hit New All-Time Highs

H3: Kalshi Leads the Charge With Over $7 Billion in Weekend Volume

Prediction markets recorded a historic weekend, with total notional trading volume exceeding $9.4 billion, according to data from Aldrin Research and TickerTracker. The standout performer was Kalshi, which alone accounted for $7.13 billion in volume across Saturday and Sunday. Sunday’s figure of $3.68 billion broke the previous daily record of $3.45 billion set just one day earlier.

What Drove the Surge?

Key Insight: Combos accounted for more than 50% of total volume on every major platform, highlighting a shift toward complex, multi-leg wagers that offer higher potential payouts but lower probability of winning.

H3: Why This Matters for the Industry

The sustained growth in prediction market volume signals a convergence of sports betting, financial speculation, and political forecasting. Platforms like Kalshi are blurring the lines between gambling and financial derivatives, attracting both retail traders and institutional interest. This trend is likely to attract increased regulatory scrutiny as lawmakers grapple with how to classify these products.

H2: Nebraska’s Online Sports Betting Push Heats Up

H3: DraftKings and FanDuel Inject Another $7 Million Into Campaign

As Nebraska voters prepare to decide on online sports betting in a November 3 vote, major sportsbooks are doubling down on their lobbying efforts. DraftKings and FanDuel each contributed an additional $3.5 million to the Tax Relief Nebraska campaign, according to the latest financial filing. BetMGM added another $250,000, bringing the campaign’s total contributions from July 28 to September 29 to $7.25 million.

H3: What Voters Will Decide

Nebraskans will consider two separate measures:

  1. A constitutional amendment allowing the legislature to authorize online sports wagering.
  2. A regulatory framework establishing licensing, taxation, and oversight rules.

If passed, the law would permit up to 12 mobile sportsbooks partnering with Nebraska’s six existing gaming facilities (casinos and racetracks).

Context: Nebraska currently allows in-person sports betting at licensed venues, but online wagering remains prohibited. This vote could make Nebraska the latest state to join the rapidly expanding U.S. online sports betting market, which is now legal in over 30 states.

H3: What’s at Stake

H3: Polymarket Takes Dutch Regulator to Court

Polymarket, the decentralized prediction market platform, is challenging an enforcement action that effectively banned it from operating in the Netherlands. The company argues that its contracts should be regulated as financial instruments rather than gambling products.

The Core Dispute

Broader Implications

Polymarket has previously discussed its regulatory classification with European and U.K. regulators, arguing that prediction markets should be treated similarly to financial derivatives or stock indices. If the Dutch court rules in Polymarket’s favor, it could set a precedent that reshapes how prediction markets are regulated across Europe.

H3: CFTC Approves Kalshi’s Stock-Index Futures Contract

In a significant regulatory development, the Commodity Futures Trading Commission (CFTC) has approved a Kalshi futures contract tied to a broad U.S. stock index. This marks another step in Kalshi’s expansion beyond event-based contracts (e.g., election outcomes, sports scores).

Key Details

Context: This approval signals that U.S. regulators are willing to accommodate innovative financial products that combine elements of futures, swaps, and event contracts—at least on a limited, experimental basis.

A new study published in the American Journal of Preventive Medicine documents a sharp increase in emergency department visits involving gambling disorders after Ontario transitioned from a single-operator model to an open online gambling market in 2022.

Key Findings

Limitations and Caveats

Implication: This study adds to a growing body of evidence that liberalizing gambling markets can lead to measurable public health costs, especially among young men—a key demographic for sportsbooks.

H2: Academic Research Debunks Political Bias Claims

H3: New Study Finds No Systematic Partisan Bias in Election Markets

A working paper by Dartmouth economist Eric Zitzewitz, published by the National Bureau of Economic Research (NBER), analyzed election prediction market data from 1880 through 2025 and found no consistent political bias favoring either side.

Key Takeaways

Other Pricing Biases Identified

Limitations

Why This Matters: The findings lend credibility to prediction markets as a forecasting tool, suggesting that even if traders have political leanings, the market mechanism corrects for individual biases. However, other structural biases (like longshot overpricing) remain.

H2: Business and Market Moves

H3: Maverick Owner Buys Back Eight Washington Casinos

Maverick Gaming owner Eric Persson announced he is buying back eight Washington casinos that had been named in closure notices, a move that could preserve approximately 850 jobs.

Properties Involved

Background

Context: Washington has a unique gambling landscape where tribal casinos hold exclusive rights to most forms of gambling. The Maverick saga highlights the financial risks and legal complexities of operating in such a regulated environment.

H3: Bank of America Sees Big Upside for DraftKings in Prediction Markets

Bank of America upgraded DraftKings stock to “Buy” from “Neutral” on Monday, citing the potential for prediction markets to become a meaningful earnings contributor—even as legal uncertainty hangs over the sector.

Analyst Reasoning

Market Reaction

Why This Matters: The upgrade underscores a growing belief that prediction markets are not just a niche hobby but a potentially lucrative vertical for established sportsbook operators—albeit one fraught with regulatory risk.

H2: Conclusion and Takeaways

The past week has demonstrated that the gambling and prediction market industry is in a state of rapid, multifaceted evolution. Key themes include:

  1. Volume explosion: Prediction markets are seeing unprecedented activity, driven by sports and combos.
  2. Regulatory tug-of-war: From Nebraska’s ballot measures to Polymarket’s Dutch court case, the legal landscape is being reshaped in real time.
  3. Public health concerns: New evidence from Ontario raises questions about the social costs of expansion.
  4. Market confidence: Academic research supports the integrity of election markets, while analysts see big revenue potential for operators.

As the industry continues to blur lines between gambling, finance, and forecasting, stakeholders—investors, regulators, and the public—will need to stay informed and engaged.
