Resumen

"Rothera Skyrockets to Third in Prediction Market Rankings, Disrupting Industry Landscape" Rothera, Robinhood's newly launched prediction market platform, has rapidly climbed to become the third-largest player in the sector by trading volume, trailing only giants Kalshi and Polymarket. Its growth is attributed not to attracting new users, but to migrating existing Robinhood user orders away from partner Kalshi. Previously, Robinhood served as a major distribution channel for Kalshi, accounting for an estimated 25%-35% of its volume. With the launch of Rothera, Robinhood now internally executes events like World Cup contracts, capturing revenue that was previously shared with Kalshi. Data shows Rothera's weekly trading volume surged from $21.9 million to $559 million within weeks, reaching nearly one-fifth of Polymarket's volume. Analysts estimate Robinhood's prediction market business could generate around $10 billion in annual revenue at this pace, potentially surpassing its historical crypto revenue peak. In response, Kalshi is reportedly exploring new distribution channels by engaging with investment banks for a potential IPO, requiring them to integrate their systems with Kalshi to access institutional clients. This shift highlights a new competitive focus in prediction markets: controlling user access and distribution channels rather than just product offerings.

Last week, Odaily Planet Daily published an article titled "The First Prediction Market Stock Appears!", which primarily mentioned that Robinhood is intercepting orders that previously needed to be executed via Kalshi by building its own prediction market, Rothera. This move aims to reduce revenue sharing with Kalshi and retain profits within its own ecosystem.

Although it was anticipated that Rothera would not face the typical cold start problems of other competitors, its data performance over the past week has still far exceeded our previous expectations. After all, it's hard to imagine that a platform, just launched half a month ago, could directly parachute into third place in the highly competitive prediction market track, trailing only the two giants, Kalshi and Polymarket.

Data from Artemis shows that for the week ending June 8th, as a new platform, Rothera's weekly trading volume was only $21.9 million, still showing a significant gap compared to second-tier platforms like Opinion, Predict, and Limitless. However, for the week ending June 15th, Rothera's weekly trading volume directly jumped to industry third place, reaching $276 million. In the latest week ending June 22nd, Rothera's weekly trading volume has increased to $559 million, almost one-fifth of Polymarket's.

Atypical Growth Case (Can skip if you've read the previous article)

It's important to clarify that Rothera's rise is essentially not due to creating incremental users (though some users may have entered due to the World Cup), but rather a migration of existing orders, not the creation of new users.

Over the past year or so, Robinhood has been one of Kalshi's most important distribution channels. Leveraging tens of millions of retail users and mature access to stock, options, and cryptocurrency trading, Robinhood has funneled a large volume of orders to Kalshi. Piper Sandler analysts estimated that trades completed through the Robinhood channel accounted for about 25%-35% of Kalshi's total trading volume.

The problem is that while these orders came from Robinhood users, they didn't belong to Robinhood itself. Under the previous cooperation model, Robinhood acted more like a front-end traffic portal, while Kalshi was the true infrastructure provider responsible for matching, clearing, and settlement. Revenue generated from each transaction needed to be shared between the two parties.

Rothera is the weapon Robinhood is using to break this profit-sharing model. Since early this month, Robinhood has begun migrating some World Cup-related event contracts to be executed internally on Rothera. This means a large volume of orders that might have previously gone to Kalshi are now retained within Robinhood's own system.

Therefore, in a sense, the surge in Rothera's trading volume is less of a threat to other prediction markets like Polymarket, Predict, or Limitless, and more akin to directly "draining blood" from Kalshi.

Robinhood's Value Capture

The rapid growth of Rothera most directly strengthens Robinhood's ability to capture value from prediction market-related orders on this platform.

Hood House, an investment research media outlet long tracking Robinhood, combined public data to state that as of June 20th, Robinhood's prediction market business traded a total of 34,700 contracts daily, corresponding to daily revenue of approximately $4.9 million.

Hood House then disclosed its calculation logic:

Rothera (primarily hosting World Cup-related markets) daily trading volume had reached 137 million contracts, corresponding to a trading value of approximately $47 million;
For comparison, Kalshi's total daily trading volume was about 1.5 billion contracts, corresponding to a trading value of about $416 million; excluding World Cup-related markets, Kalshi's trading volume was about 1 billion contracts, corresponding to a trading value of about $260 million;
Considering that Robinhood users still contribute about 20% (a conservative estimate) of Kalshi's non-World Cup market trading volume, this means that about 210 million contracts and $52 million in trading value from Kalshi's non-World Cup related event contracts were completed via Robinhood.

Hood House further made an aggressive estimate based on this, stating that if this growth rate continues, Robinhood's prediction market business has the opportunity to achieve revenue on the scale of billions of dollars this year. This figure even surpasses the historical peak of Robinhood's cryptocurrency-related revenue, which was approximately $900 million achieved in 2025.

Kalshi's Countermeasure: Finding New Channels

Faced with Rothera's rapid rise, Kalshi is clearly aware of the problem.

For Kalshi, Robinhood was both a partner and one of the most important traffic sources in the past. However, as Robinhood begins migrating more and more orders to its own platform, the relationship between the two has become one of direct competition.

A recent piece of news disclosed by The Information may reveal Kalshi's response strategy. Informed sources revealed that Kalshi has begun early, informal discussions with several investment banks regarding a potential future IPO. More notably, Kalshi has presented a clear requirement in its communications with these banks — to be considered for underwriting qualifications in the future IPO, these institutions need to prioritize completing technical integration of their systems with Kalshi. This would allow their institutional clients to directly participate in trading event contracts on the Kalshi platform.

In other words, Kalshi is leveraging the IPO opportunity to find new distribution channels, integrating prediction markets into the client networks of banks, brokerages, and other financial institutions. This also represents a subtle change occurring in the competitive landscape of the prediction market industry. In the past, the focus was on who could offer more contracts or design better products. Now, as prediction markets gradually move into the mainstream financial system, the competitive focus is shifting to another dimension — whoever controls the user access points can more effectively control value.

The rise of Rothera has already demonstrated the significance of distribution capability. Parachuting into third place in the track seems effortless. Challenging Kalshi and Polymarket in the future may not seem like an impossible task either.

As Channel Dividends Fade, What Can DeFi Protocols Rely On to Resist Giant Harvesting?

The article discusses how major tech companies like Coinbase, Stripe, and Kraken are increasingly acquiring or building their own underlying infrastructure to capture profits, moving away from relying on external DeFi protocols. It uses the example of Coinbase's Base blockchain, which generates sequencing fees for Coinbase from protocols like Morpho that deploy on it. Similarly, Stripe acquired Bridge to capture stablecoin yield instead of paying it to Circle, and Kraken bought NinjaTrader for its derivatives licenses. The core argument is that when channel-based advantages (like user traffic) fade, control over the profit-generating infrastructure becomes critical. While this could lead to a future dominated by a few integrated giants, the article suggests a more balanced outcome is possible. Protocols that have already achieved deep, multi-chain integration and embedded themselves into corporate backends create high switching costs, making them difficult to replace. Examples include Morpho (despite reliance on Base, it's widely deployed) and Uniswap. The piece concludes that the race between institutional expansion and open-source protocol proliferation will ultimately shape the industry's structure.

The Computing Power Dilemma in the Sino-US AI Rivalry

The Sino-US AI rivalry faces a fundamental bottleneck: the widening compute power gap. While Chinese AI chip companies have seen investment surges, their current focus remains largely on the less demanding inference market. The real challenge lies in the high-end training chip sector, crucial for developing cutting-edge large language models (LLMs), where Nvidia holds a near-monopoly. The compute disparity is stark. US tech giants like Meta, Google, and xAI command massive GPU clusters, enabling them to train trillion-parameter models rapidly. Estimates suggest US data center count and total compute capacity significantly outstrip China's. This "brute force" advantage allows for faster model iteration and exploration of larger parameter scales, with top US models reportedly leading their Chinese counterparts by 8 to 15 months. Chinese alternatives, such as Huawei's Ascend and others from companies like Moore Thread and Biren, are emerging. They show promise in inference and some training scenarios, closing the performance gap with mid-range Nvidia products. However, the core hurdle extends beyond raw chip performance to the entrenched software ecosystem, exemplified by Nvidia's CUDA platform. The path forward involves "walking on two legs": navigating import restrictions while heavily investing in the domestic chip industry. Though still in a catch-up phase, China's vast market, talent pool, and capital are fostering progress. The ultimate test is whether Chinese firms can build a competitive hardware-software ecosystem to power the next generation of AI.

He Kaiming's Team's New Work: After Deleting VAE and Private Data, Text-to-Image Generation Becomes Even Stronger

KaiMing He's team introduces **MiniT2I**, a minimalist text-to-image (T2I) model that challenges the complexity of mainstream approaches. It eliminates components commonly considered essential: the VAE encoder-decoder, AdaLN conditioning mechanisms, auxiliary losses, private training data, and post-training alignment stages like RL/DPO. Instead, it uses a pure flow-matching objective trained directly on RGB pixels. The model employs a simplified **MM-JiT** Transformer architecture. It removes AdaLN blocks for conditioning and instead prepends two lightweight text adapter blocks to a standard pre-norm Transformer, allowing frozen T5 text features to adapt to the denoiser. Training follows a two-stage, LLM-like paradigm using only public datasets: pre-training on LLaVA-recaptioned CC12M for coverage, followed by fine-tuning on ~120k high-quality image-text pairs. With just 258M parameters (B/16), MiniT2I achieves competitive scores (0.87 on GenEval, 84.2 on DPG-Bench), outperforming larger pixel-space models. Scaling to 912M parameters (L/16) yields results comparable to SD3-Medium (~2B parameters) in style, composition, and imagination, though it lags in text rendering and named entities due to public data limitations. Key advantages include lower computational cost (~570 GFLOPs vs. ~1379 for latent models) and architectural simplicity. Acknowledged limitations include patch boundary artifacts in pixel space, side effects of high CFG scales, resolution ceilings for sequences longer than 1024 tokens, and the aforementioned data bottlenecks. The work demonstrates that high-performance T2I generation is possible with a radically simplified, publicly reproducible baseline.

The Insurance Industry Faces Its Biggest Competitor: Are Prediction Markets the "Barbarians at the Gate"?

The insurance industry, long a stable "ballast" in the economy, may face a significant challenge from the rise of prediction markets, which are beginning to function as a new form of risk hedging and insurance. Platforms like Kalshi and Polymarket are demonstrating their utility in areas traditionally dominated by insurers. Examples include Kalshi's partnership with sports insurance broker Game Point Capital to offer more cost-effective hedging for NBA team performance bonuses, and Polymarket's collaboration with real estate platform Parcl, allowing users to hedge against housing price fluctuations in major US cities. A New York bar also used Kalshi to hedge a marketing promotion tied to an NBA game outcome, highlighting prediction markets' potential for small business risk management. These markets offer advantages over traditional insurance and sports betting in transparency, liquidity, and flexibility. They allow information monetization across a wider range of events, act as neutral platforms rather than direct counterparties, and provide clearer pricing. A historical precedent is the "Mattress Mack" marketing campaigns, which used sports betting for large-scale customer refunds, but prediction markets offer a more systematic and accessible model. Experts like SIG CEO Jeff Yass see their potential for efficient, parameter-based risk sharing, such as for weather-related property damage. However, challenges remain, including liquidity issues, unclear regulatory boundaries, and potential manipulation of event outcomes. Despite these hurdles, prediction markets represent a growing competitive force for both traditional gambling platforms and segments of the insurance industry.

Insurance Industry Faces Its Biggest Competitor: Are Prediction Markets the 'Barbarians at the Gate'?

"Insurance Industry Faces New Rival: Are Prediction Markets the 'Barbarians at the Gate'?" Prediction markets, exemplified by platforms like Kalshi and Polymarket, are emerging as potential disruptors to the traditional insurance industry by offering alternative risk-hedging mechanisms. These markets allow users to bet on specific event outcomes, effectively creating a form of customizable, on-demand insurance. Key examples highlight this shift. In sports, Kalshi partnered with insurance broker Game Point Capital to provide NBA teams with more affordable options to hedge performance bonuses compared to traditional insurers. In real estate, Polymarket's collaboration with Parcl lets users speculate on city-specific housing price indices, allowing homeowners to hedge against price drops or buyers against price increases. Furthermore, businesses like a New York bar have used Kalshi to hedge marketing promotions (e.g., offering free drinks if a team wins), framing the transaction explicitly as placing a "hedge." The article argues prediction markets offer advantages over traditional insurance and even sports betting in transparency, liquidity, and flexibility. They provide a wider range of event coverage, act as neutral platforms rather than counterparties, and offer clearer pricing. The piece cites historical precedents like large "refund promotion" hedges by businesses using sportsbooks but notes prediction markets modernize the concept. However, challenges remain for widespread adoption as an insurance alternative, including limited liquidity in some markets, unclear regulatory status, and potential vulnerabilities in event resolution mechanisms. Despite these hurdles, prediction markets are positioning themselves as new tools for risk management, directly challenging certain segments of the conventional insurance landscape.
