Trepa and Fireplace Shut Down: Prediction Markets Enter a Duopoly Era

Woofun AI reports that the simultaneous closure of two distinct prediction market projects signals industry consolidation, as Trepa and Fireplace exit the market while Polymarket and SOL-based ecosystems face a new reality. The exits, attributed to Ma He and Foresight News, highlight a structural shift where only giants survive, leaving shell innovations to fail. This phenomenon marks the end of an experimental phase, forcing a re-evaluation of viability in a sector increasingly defined by concentration rather than diversity.

The closures are not isolated incidents but rather the inevitable outcome of a highly concentrated landscape, where the middle class of projects has effectively vanished. This trend underscores the difficulty for new entrants to compete against established players with massive capital and regulatory advantages. The industry is moving towards a duopoly era, where the barriers to entry are significantly higher than previously anticipated.

This shift has profound implications for future innovation and investment strategies in the prediction market space.

The shutdown timeline for Trepa was meticulously planned to minimize user disruption while ensuring a clean exit. The final round of bets was scheduled to conclude on August 12, 2026, after which no new rounds would be held. This date marked the end of all active trading activities on the platform. Following this, the app remained online until September 30 to allow users sufficient time to withdraw their funds. This period was crucial for maintaining trust and ensuring that users could access their assets before the platform went dark.

After September 30, the app became completely inaccessible, signaling the final end of the project. This structured approach to shutdown reflects the team's commitment to responsible closure, even in the face of failure. The timeline also highlights the operational challenges faced by the project, as it struggled to maintain user engagement and liquidity in its final months. The decision to keep the app online for fund withdrawals was a critical step in managing the fallout from the shutdown.

Fireplace followed a similar but slightly different shutdown timeline, reflecting its unique position as a professional trading terminal. The platform stopped accepting trades on August 15, marking the end of its operational activities. This date was chosen to allow users to close their positions and withdraw their funds before the platform went offline. The website was scheduled to shut down at 23:59 UTC on September 30, providing a clear deadline for users to take action. This timeline was designed to minimize confusion and ensure a smooth transition for users.

The decision to stop accepting trades before the website shutdown was a strategic move to prevent any last-minute issues or disputes. The shutdown process was handled with care, reflecting the team's professionalism and commitment to their users. Despite the short lifespan of the project, the team managed to execute a orderly shutdown, which is a testament to their operational capabilities. The timeline also underscores the challenges faced by third-party terminals in a market dominated by giants.

Trepa's origins can be traced back to the Bybit × DMCC hackathon in November 2024, where it initially emerged as a Telegram mini-program on TON. The project aimed to predict survey results, leveraging the power of blockchain technology to create a new form of prediction market. It went on to participate in several subsequent hackathons, including Sonic SVM, Superteam Korea, and Colosseum Breakout, gaining valuable experience and exposure. Trepa was also part of Balaji Srinivasan's Network School, which provided additional mentorship and resources.

In August 2025, Trepa raised $420,000 in Pre-Seed funding, led by Colosseum, with contributions from Ignite Capital, The Balaji Fund, and Balaji himself. This funding round was a significant milestone for the project, providing the necessary capital to launch and scale. The involvement of prominent investors like Balaji Srinivasan added credibility to the project and attracted attention from the crypto community. The funding also allowed Trepa to develop its unique 'precision prediction' mechanism, which set it apart from traditional binary prediction markets.

The project's journey from a hackathon idea to a funded startup highlights the potential for innovation in the prediction market space.

The leadership team behind Trepa, consisting of Jong-Chan Chung (CEO) and Leon Meka (CTO), articulated a clear product philosophy centered on 'precision predictions.' They believed that users were willing to pay for precision, not just for being right about direction. This philosophy drove the development of a precision-weighted prize pool mechanism, where smaller errors meant a higher share of the rewards. The team referred to this as 'precision predictions,' aiming to create a third path beyond traditional binary prediction markets. They opted for a prize pool structure, aware that this meant they couldn't predict odds in advance and that once funds were invested, they couldn't be withdrawn.

However, they saw this as the only way to fairly reward accuracy while keeping things intuitive for ordinary users. The team's commitment to this philosophy was evident in their product design and marketing efforts. They believed that by focusing on precision, they could attract a new segment of users who were dissatisfied with the simplicity of binary markets. This approach was innovative and had the potential to disrupt the existing prediction market landscape.

However, the execution of this philosophy proved to be more challenging than anticipated.

Woofun AI data shows that Trepa's operational failures were multifaceted, stemming from both product design and market dynamics. The cognitive burden of needing precision to decimal places reduced enjoyment, making the product less appealing to a broad audience. The concurrency trap was another significant issue, as there needed to be enough participants at the same time for a meaningful prize pool. Trepa eventually limited active hours to one hour daily between 1–2 UTC, forcing users to schedule their activities around this window. This created significant retention pressure, as users were unlikely to engage with the platform consistently.

The growth model itself was contradictory, as expanding the user base required more assets and time windows, which in turn reduced concurrency and worsened the system. By the time the team realized this conflict, it was already too late. The user base was also overestimated, with referral mechanisms proving ineffective and paid KOLs having little impact. Geographical restrictions, funding thresholds, and the fact that the actual number of active crypto users was far lower than public data suggested meant that the real active user base for such products was only in the hundreds of thousands, not millions. These factors combined to create a perfect storm of challenges that Trepa was unable to overcome.

Fireplace, launched on January 27, 2026, aimed to become the 'Bloomberg Terminal for prediction markets.' It raised $1.5 million in Pre-Seed funding in February, led by Frachtis, with contributions from White Star Capital and others. Founders Sumer Malhotra (CEO) and Akshay Rajagopal (CTO) had previously argued that what prediction markets lacked were professional-grade infrastructure and execution layers. The platform offered more advanced charts, position management, wallet and whale tracking, market discovery, and execution tools.

Its goal was to provide a comprehensive solution for professional traders in the prediction market space. The team believed that by offering these advanced features, they could attract a niche segment of users who were willing to pay for a premium experience. The funding round provided the necessary capital to develop and launch the platform, allowing the team to focus on building a robust and user-friendly product. The involvement of experienced investors like Frachtis and White Star Capital added credibility to the project and helped attract early users.

However, the market conditions were not favorable for a third-party terminal, as the giants in the space were already offering similar features.

Fireplace's market challenges were primarily driven by fee structures and competition with Polymarket. Some users pointed out that a transaction fee of around 1% was unfavorable for large funds, representing a high cost premium compared to trading directly on Polymarket. In an environment where giants dominate traffic and liquidity, it's difficult for third-party terminals to establish sustainable independent value.

Additionally, once Polymarket improved its own offerings, the differentiation of third-party terminals disappeared quickly. The core advantages of prediction markets lie in liquidity and trading volume, not the interface—interfaces can be copied, but liquidity cannot. This realization was a significant blow to Fireplace, as it undermined the core value proposition of the platform. The team had hoped to attract users by offering a more professional and feature-rich experience, but the high fees and lack of unique liquidity made it difficult to compete. The market feedback was clear, and the team had to make the tough decision to shut down the platform. The shutdown of Fireplace highlights the challenges faced by third-party terminals in a market dominated by giants.

The duopoly landscape is dominated by Kalshi and Polymarket, with significant valuations and recent financing rounds. As of June 21, data showed that Kalshi and Polymarket led all competitors in terms of market turnover, with Kalshi even surpassing Polymarket in growth rate. In May this year, Kalshi completed a $1 billion financing round, led by Coatue Management, pushing its valuation to $22 billion. At the end of June, Kalshi was in talks for another round of financing, valued at around $40 billion, with completion potentially occurring in the third quarter of this year.

Meanwhile, another competitor, Polymarket, was said to be in early discussions with potential investors. On August 4, Polymarket planned to raise around $1 billion at a valuation exceeding $20 billion. These financing rounds highlight the confidence of investors in the prediction market space and the potential for significant returns. The valuations of Kalshi and Polymarket are a testament to their market dominance and the scalability of their business models. The duopoly landscape is likely to persist, as the barriers to entry are high and the advantages of scale are significant. This concentration of power has profound implications for the future of the prediction market industry.

This disparity determines the survival space for smaller projects, as Kalshi is a U.S.-based platform regulated by the CFTC, focusing on sports and event contracts. It has smoother access to institutional funds, compliant channels, and retail distribution, with sports contracts accounting for most of its trading volume. Polymarket, on the other hand, targets crypto-native users globally, with a higher proportion of political, geopolitical, and crypto-related markets. It boasts greater liquidity depth and brand recognition in the crypto community but faces more constraints due to compliance and geographical factors.

Under such circumstances, it is difficult for innovation at the mechanism level or tool layer to develop independent growth drivers. When over 80% of trading volume is captured by two giants, the remaining niche space isn't enough for startups to sustain a viable business model. The Trepa team wrote a calm statement: they still believe that the idea that 'people are willing to pay for precise measurement' has value, but they haven't found a way to turn it into a business. Fireplace chose to open up its technical achievements to later entrants, providing a migration period before quietly withdrawing.

The first batch of projects to try new mechanisms or interfaces in prediction markets are starting to fail. This doesn't mean prediction markets have reached their peak—on the contrary, Kalshi and Polymarket's trading volumes remain high. The real signal is that this sector is rapidly shifting from a diverse landscape to one dominated by giants. For newcomers, either creating truly unique differentiators or partnering with giants to complement their offerings is necessary—otherwise, the time window might be shorter than expected.
