Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Underdog Fantasy launched in summer 2020 as a lean, product-focused DFS startup founded by Jeremy Levine, Brandon Stakenborg, and Trevor John, all veterans of previous DFS ventures StarStreet and DRAFT. The platform differentiated through innovative Best Ball tournaments that eliminated weekly roster management. With minimal regulatory footprint, no significant marketing spend, and a small team, enshittification vectors were minimal across all dimensions.
Underdog raised $35M in Series B funding at a $485M valuation and expanded from Best Ball into Pick'em contests, which became its primary revenue driver. The company acquired Synkt Games for New York market access and obtained an Ohio sportsbook license, signaling ambitions beyond DFS. Pick'em's opaque line-setting methodology and deposit bonus playthrough requirements introduced early monetization friction, while the growing valuation created investor pressure for rapid expansion.
Florida's cease-and-desist forced Underdog out of a major market in late 2023, while CEO Levine publicly accused DraftKings and FanDuel of anti-competitive lobbying. Ad spend exceeded $25M annually as the company pursued aggressive user acquisition with celebrity endorsements. Employee reviews surfaced concerns about nepotism, burnout, and alleged racial discrimination in layoffs. Underdog registered as a Texas lobbying client and began navigating an increasingly hostile regulatory landscape across multiple states.
Underdog's strategic pivot accelerated through its partnership with Crypto.com to offer federally regulated prediction markets, while simultaneously facing a $17.5M fine and New York exit, a preemptive California lawsuit that failed, and class action lawsuits alleging illegal sports betting. The $1.23B Series C valuation intensified investor pressure. The company abandoned its sportsbook entirely by December 2025 and co-founded the Coalition for Prediction Markets, while Arizona moved to revoke its DFS license over the Crypto.com partnership.
Underdog laid off 125 employees (20% of workforce) including two-thirds of its fraud team, citing the prediction market pivot and AI replacement. The company acquired Aristotle Exchange to bring prediction markets in-house, eliminating its Crypto.com dependency. Regulatory and legal pressure continued escalating across multiple states, while the March 2026 layoffs revealed the human cost of investor-driven strategic pivots at a company that had reached unicorn status just a year earlier.
Alternatives
The largest pick'em DFS platform and Underdog's closest direct competitor in the same format. Also facing regulatory scrutiny and class action lawsuits for similar practices, but it's currently the most viable alternative for users who want the pick'em format. Easy lateral move — the interface and contest structure are nearly identical. Check state availability.
Established platform with a longer track record than Underdog and traditional DFS contests alongside its sportsbook. More regulated and more transparent about odds. Higher implied house edge than pick'em formats, but less regulatory uncertainty. Moderate switch — the contest format is different from Underdog's Best Ball specialty.

Underdog Fantasy Launches with Best Ball Contests
Jeremy Levine, Brandon Stakenborg, and Trevor John launched Underdog Fantasy in Brooklyn, New York, offering innovative Best Ball draft contests that eliminated the need for weekly lineup management. The founders brought experience from previous DFS ventures StarStreet (sold to DraftKings in 2014) and DRAFT (acquired by Flutter/Paddy Power Betfair in 2017). The platform debuted with a $1 million Best Ball tournament.
Series A Raises $10M from Celebrity Investors
Underdog Fantasy closed a $10 million Series A round with investors including Mark Cuban, Kevin Durant, rapper Nas, DJ Kygo, and ESPN's Adam Schefter. The round was led by tech investor Kevin Carter with participation from HBSE Ventures (owners of the Philadelphia 76ers). The celebrity investor roster signaled growing industry credibility for the startup.
Series B Values Underdog at $485M with BlackRock Backing
Underdog raised $35 million in Series B funding at a $485 million valuation, with participation from BlackRock and Acies Investments. The round represented a major validation for the company's Pick'em product, which had become its primary revenue driver alongside the original Best Ball contests. The elevated valuation intensified pressure to demonstrate rapid growth and revenue expansion.
Underdog Acquires Synkt Games for New York License
Underdog acquired Synkt Games to obtain a temporary interactive fantasy sports license in New York, originally issued to Synkt in 2016. The acquisition allowed Underdog to operate DFS contests in New York, though the inherited license's restrictions on contest types would later lead to a $17.5 million regulatory fine when Underdog offered contests beyond Synkt's original approved formats.
Underdog Granted Ohio Online Sportsbook License
The Ohio Casino Control Commission awarded Underdog a license to operate as an online sports betting service provider, partnering with the Cincinnati Reds for market access. This marked Underdog's first entry into traditional sports wagering beyond daily fantasy sports, signaling a broader monetization strategy beyond DFS contests.
Florida Issues Cease-and-Desist to Underdog Over Pick'em
The Florida Gaming Control Commission sent cease-and-desist letters to Underdog Fantasy, PrizePicks, and Betr, ordering them to stop offering 'illegal bets or wagers.' The FGCC determined that pick'em fantasy contests played against the house constituted illegal sports betting under Florida law. Underdog, PrizePicks, and Betr agreed to cease operations in Florida by March 1, 2024.
Third-Party Analysis Reveals Pick'em House Edge Structure
The Moods Newsletter published a detailed mathematical analysis of Underdog's Pick'em payout structure, revealing an effective house edge of approximately 15-25% depending on the number of legs selected. The analysis showed that each leg's implied odds in 3-leg and 5-leg entries are approximately -122, with Underdog adjusting statistical lines rather than applying traditional sportsbook vigorish.
Ad Spend Tops $25M with Brand Awareness Campaign
Marketing Brew reported that Underdog's advertising spend topped $25 million in 2023, increasing over 60% year-over-year. The company launched its biggest-budget campaign, 'The Dogs Are All Here,' shifting from direct-response advertising toward brand awareness marketing. Cable ad dollars hit $20.8 million, a 40% year-over-year increase, with ads running on programming including Friends, Catfish, and Rick and Morty.
Underdog Launches Peer-to-Peer Pick'em Champions Format
In response to regulatory pressure over house-banked pick'em contests, Underdog launched 'Pick'em Champions,' a peer-to-peer contest format in Alabama, Mississippi, and Wyoming. The format allowed users to compete against each other rather than the house, designed to comply with state gambling laws that prohibit house-banked wagering. This regulatory adaptation allowed Underdog to continue operating in states where traditional pick'em was banned.
CEO Levine Accuses DraftKings and FanDuel of Anti-Competitive Lobbying
Underdog CEO Jeremy Levine publicly accused DraftKings and FanDuel of using their lobbying contacts to disadvantage newer DFS companies. Levine alleged that the Sports Betting Alliance, backed by DraftKings and FanDuel, was petitioning state officials to classify pick'em contests as games of chance rather than games of skill. The public salvo marked Underdog's entry into active political combat with established operators.
Glassdoor Reviews Cite Burnout, Understaffing, and Nepotism
Employee reviews on Glassdoor described burnout as a significant issue at Underdog, particularly in understaffed departments. Reviewers alleged nepotism in leadership appointments, claiming that unless employees were part of an 'inner circle' they would not receive recognition or promotion. One review alleged racial discrimination in layoffs, stating 'the first people to be cut tend to be people of color.' The company held a 3.9 out of 5 Glassdoor rating with 76% recommending the workplace.
Bill Belichick Signs Brand Ambassador Deal with Underdog
Former New England Patriots head coach and six-time Super Bowl champion Bill Belichick partnered with Underdog Fantasy to create and host a weekly football show called 'Coach, with Bill Belichick.' The partnership represented a major celebrity endorsement coup and further escalation of Underdog's aggressive marketing spend to compete with DraftKings and FanDuel for user acquisition.
Third-Party Tools Expose Pick'em Line Movement Lag
OddsJam's Fantasy Optimizer demonstrated that Underdog's Pick'em lines lagged behind the broader sportsbook market when injuries, weather, or other factors moved lines. The tool enabled sophisticated users to identify and exploit stale lines in real time before Underdog adjusted its projections, creating informational asymmetries between casual and sharp players. The lag underscored the opacity of Underdog's line-setting process, as users could not see when or how lines would be updated.
Series C Values Underdog at $1.23B Unicorn Status
Underdog closed a $100 million Series C round led by Spark Capital, valuing the company at $1.23 billion and nearly tripling its previous $485 million Series B valuation. The unicorn status intensified pressure to justify the valuation through aggressive revenue growth and market expansion, even as regulatory headwinds mounted in multiple states. The company claimed profitability and projected nearly $500 million in revenue for 2025.
Class Action Alleges Underdog Operates Illegal Sports Betting
A federal class action lawsuit (Ballentine v. Underdog Sports LLC) was filed in the Eastern District of New York, alleging Underdog operates an 'unlicensed sports betting platform that it falsely markets as an interactive fantasy sports game.' Filed by Lieff Cabraser, the suit claimed Underdog's Pick'em contests are functionally indistinguishable from proposition betting at traditional sportsbooks, making them illegal in most states where the company operates.
Underdog Pays $17.5M Fine and Exits New York
Underdog Fantasy agreed to pay $17.5 million and withdraw all contests from New York after the State Gaming Commission determined the company violated its temporary license by offering contests not authorized under the original Synkt Games permit. The fine was calculated based on Underdog's New York revenue. The company simultaneously expanded into New Jersey and Delaware, and later returned to New York in May 2025 with a new temporary license limited to draft-style DFS only.
BBB Complaint Describes Account Ban After Winning, Withheld Funds
A BBB complaint filed in May 2025 described Underdog banning a user's account without due process and withholding $300 in accumulated winnings. The complaint pattern matched a broader trend of users reporting that Underdog accepted deposits and wagers without issue but flagged, suspended, or terminated accounts when significant wins occurred. The asymmetric treatment between deposit ease and withdrawal difficulty reinforced concerns about the platform's dark pattern design.
Underdog Files Preemptive Lawsuit Against California AG
Underdog filed a lawsuit against California Attorney General Rob Bonta in Sacramento County Superior Court, seeking to prevent the release of a legal opinion declaring daily fantasy sports illegal gambling under California law. About 10% of Underdog's revenue came from California. Judge Jennifer Rockwell rejected the request on July 2, finding Underdog had delayed too long and failed to demonstrate immediate harm. The AG subsequently issued the opinion, triggering four class action lawsuits against DFS operators including Underdog.
Underdog Launches Prediction Markets via Crypto.com Partnership
Underdog partnered with Crypto.com Derivatives North America (CDNA), a CFTC-regulated designated contract market, to offer sports event contracts through the Underdog app in 16 states. Underdog became the first sports gaming operator to offer federally regulated prediction markets, marking a strategic pivot from state-regulated DFS toward CFTC-supervised derivatives. Event contracts allowed users to trade on sports outcomes including spreads, totals, and championship futures.
Glassdoor Reviews Describe Worsening Culture Amid Strategic Pivot
Employee reviews posted to Glassdoor in late 2025 described deteriorating workplace conditions at Underdog as the company underwent its prediction market pivot. Reviews cited 'extremely toxic work culture that pretends to care on the surface,' multiple firings without performance improvement plans, and persistent nepotism. Long-term employees described being 'pushed out,' while the company's dual-CEO governance structure with co-founders Levine and Stakenborg concentrated decision-making without external board oversight typical of companies approaching this scale.
Prediction Picks Contract Pricing Methodology Remains Opaque
Underdog's help center documentation for its new Prediction Picks product described event contract prices as trading between $0.01 and $0.99 'based on the outcome's probability,' without disclosing how those probabilities were calculated or what the platform's spread was between buy and sell prices. The early cash-out feature allowed users to sell positions at 'current market value' without transparency into how that value was determined, adding another layer of algorithmic opacity to the prediction market product.
Playthrough Requirements Create Withdrawal Friction for Depositors
Underdog's deposit match promotion terms required customers to play through the combined total of their deposit and bonus in qualifying contests before withdrawing any promotional funds, with a 14-day window before forfeiture. Bonus funds were applied to entry fees before customer-deposited funds, ensuring promotional cash cycled through the platform first. BBB complaints continued to surface from users who discovered these playthrough conditions only when attempting withdrawals, describing the bonus structure as misleading.
Underdog Co-Founds Coalition for Prediction Markets
Underdog joined Kalshi, Crypto.com, Coinbase, and Robinhood to form the Coalition for Prediction Markets (CPM), a trade group advocating for federal CFTC oversight of prediction markets over state-level regulation. Underdog was the only gaming-focused member. The coalition launched as sports event contracts faced increasing pushback from state regulators and the established sports betting industry.
Arizona Moves to Revoke Underdog's Fantasy Sports License
The Arizona Department of Gaming issued a notice of intent to revoke Underdog's fantasy sports license, citing the company's partnership with Crypto.com for prediction markets. The ADG said Underdog was 'aiding and abetting Crypto's illegal conduct in Arizona' and 'providing it with a facade of legitimacy.' This marked the first time a state regulator had moved to revoke a DFS license specifically over prediction market activities.
Underdog Exits North Carolina Sportsbook, Abandons Sports Betting
Underdog closed its North Carolina sportsbook, its only remaining active state for traditional sports betting, and announced it would no longer operate a sportsbook in the United States. The company had also pulled out of a planned Missouri sportsbook launch days before wagering went live. The exit completed Underdog's strategic pivot away from state-regulated sports betting toward federally regulated prediction markets. Any unsettled futures wagers were paid out at maximum value.
Underdog Receives NFA Approval as Futures Commission Merchant
Underdog received approval from the National Futures Association to operate as a Futures Commission Merchant for its UDM LLC subsidiary, which had applied in April 2025. The NFA approval gave Underdog firmer federal regulatory standing and the ability to partner with designated contract markets beyond its Crypto.com arrangement, representing a key step in its pivot to prediction markets as a nationally available product.
Underdog Lays Off 125 Employees Including Two-Thirds of Fraud Team
Underdog laid off at least 125 employees, approximately 20% of its workforce, with cuts spanning fraud operations (two-thirds eliminated), customer support, graphics, marketing, and the drafts product team. CEO Jeremy Levine attributed the cuts to the company's transition to 'a national prediction-markets platform.' Sources indicated AI replacement played a role in the decision. Employees were informed in short meetings on February 27, after which access to company systems including email and Slack was removed.
Underdog Acquires Aristotle Exchange for In-House Prediction Markets
Underdog acquired Aristotle Exchange DCM and DCO entities from Aristotle Inc. (operators of PredictIt), gaining CFTC-registered designated contract market and derivatives clearing organization infrastructure. The acquisition allowed Underdog to host prediction markets internally rather than relying on the Crypto.com partnership, enabling the company to list and settle sports-related event contracts on its own platform. Financial terms were not disclosed.
