Billionaire Jenny Just says she could have saved ‘10 years of losses’ if she had learned this skill sooner from playing poker

Jenny Just, cofounder of PEAK6 and a former CBOE options trader, argues that poker trains decision-making under uncertainty—sharpening probability assessment, risk management, capital allocation and emotional control—and says earlier exposure could have shortened her path to success. The article highlights efforts like Just’s Poker Power to teach these skills to women, notes the growth of sports betting and prediction markets that give young men informal practice in risk-taking, cites a 2022 New York Fed study linking strategic sophistication to trader profits, and references a 2025 National Council on Problem Gambling report estimating nearly 20 million U.S. adults had problematic gambling behavior.

Analysis

Market structure: The behavioral shift described—more Gen Z men using sports betting and prediction markets—directly benefits digital sportsbooks, trading platforms and engagement-heavy social ad sellers (e.g., DraftKings, Flutter, brokerage platforms, and Meta). It increases retail orderflow, short-dated options volumes and gamma sensitivity, while land-based casinos and legacy media/linear ad sellers face downside as ad dollars and attention migrate online.

Risk assessment: Key tail risks are regulatory intervention (state/federal restrictions or advertising limits) within 12–24 months, AML/credit blow-ups from problem gamblers, and platform operational outages that could crater trust. Immediate impact (days/weeks) is volatility spikes around major sports events; short-term (months) is revenue/volume growth and higher IV in equities; long-term (years) is a structural rise in retail derivatives participation and persistently higher equity vol baselines.

Trade implications: Expect persistent elevated options flow and episodic gamma squeezes—trade around event calendars (NCAA in March, NFL preseason). Favor growth/exposure to DKNG/PDYPY and brokerages (IBKR, SCHW) and platform ad beneficiaries (META) while using option overlays to cap downside; reduce weight in land-based casino operators (MGM) and linear media where promotional spend will compress margins.

Contrarian angle: Consensus underestimates regulatory repricing risk and overestimates durable LTV of new bettors—unit economics could reverse if CAC spikes or stricter advertising rules arrive. Historical parallel: 2018–2020 retail options booms produced outsized short-term returns then sharp mean reversion when churn costs rose; if regulators act in 12–24 months, current premiums in betting equities could be overstated and vulnerable to 30–50% downside.

Key Decisions for Investors

• Establish a 1.5–2.0% long position in DraftKings (DKNG) with a 6–12 month horizon to capture incremental betting revenue; hedge downside by buying 3-month 10% OTM puts equal to 25% of the notional long size to limit drawdown to ~25–30% on a crash.
• Add a 1.0–1.5% long position in Meta Platforms (META) over 6–12 months to capture incremental engagement/ad spend from betting/prediction market advertisers; finance by trimming 0.5–1.0% exposure to linear media (e.g., DIS) and buy a 6-month 15% OTM call (50% notional) to gain leveraged upside while capping premium paid.
• Implement a pair trade: long Flutter (PDYPY or appropriate ADR) 1.0–1.5% vs short MGM 1.0–1.5% for 9–12 months, expecting online-first operators to outgrow land-based casinos; close if spread narrows by 30% or after 12 months.
• Place a tactical volatility bet: buy a 0.5–1.0% notional 30–60 day ATM straddle on DKNG ahead of March Madness (enter 2–4 weeks prior), take profits after the event or if realized vol exceeds implied vol by >10 pts; cap loss if IV collapses by >40%.
• Before increasing exposure >3% to the sector, monitor for legislative action: track (1) any federal gambling/advertising bills and committee hearings over the next 60–120 days and (2) state-level ad restrictions—if credible federal proposals emerge, reduce net long exposure by 50% within 10 trading days.
