NVIDIA Case Reopened: Accused of Concealing $1 Billion in 'Mining' Revenue, a Hidden Chapter in the AI Giant's History

Nvidia Faces Renewed Investor Lawsuit Over Alleged $1 Billion Undisclosed Crypto Mining Revenue A US judge has approved a class-action lawsuit against Nvidia and its CEO Jensen Huang. Investors allege that between 2017 and 2018, Nvidia concealed the extent to which its gaming graphics card revenue depended on cryptocurrency mining demand, misleading shareholders about associated risks. The suit claims over $1 billion in crypto-related revenue was largely reported under the "Gaming" segment, downplaying the business's exposure to volatile crypto market cycles. Following a corrective disclosure in November 2018, Nvidia’s stock fell approximately 28.5% over two days. Internal evidence, including an executive email, suggested that previous statements had positively influenced the company's stock price. This case revives a lawsuit initially filed in 2018, which had previously been dismissed. During the 2017 crypto boom and the 2020 bull market, Nvidia’s GPUs were in high demand from miners, causing shortages for gamers. The company later launched dedicated CMP mining cards. In 2022, the SEC charged Nvidia with insufficient disclosure of mining’s impact on gaming revenue, resulting in a $5.5 million settlement. The class action covers investors who bought Nvidia stock between August 2017 and November 2018. A case management conference is scheduled for April 21.

2% of Users Contribute 90% of Trading Volume: The True Portrait of Polymarket

A deep analysis of Polymarket's user base reveals a stark concentration of trading activity: just 2% of users, classified as high-frequency, high-volume professional traders (P6), generate nearly 90% of the platform's total trading volume. This contrasts with the 69% of users who are low-activity, small-scale participants (P2), driven primarily by major events like elections or sports. The study, analyzing three months of on-chain data, segments users into seven profiles based on transaction frequency (T1-T7) and volume (V1-V7). While the user base is dominated by infrequent, small-scale bettors, the trading volume is overwhelmingly controlled by a small cohort of algorithmic and systematic traders. This structural split directly influences market dynamics. Cryptocurrency markets are dominated by P6 traders, indicating heavy algorithmic activity. Sports markets attract a more diverse mix, including seasoned human bettors. Political markets have the highest share of users but are filled with event-driven, one-time participants. The findings have critical implications for fee structures. Polymarket's current tiered fees—highest for crypto (1.80%), lower for sports (0.75%) and politics (1.00%), and zero for geopolitics—are strategically aligned with the tolerance of each user profile. A flat fee could severely damage liquidity by discouraging the vital P6 segment. The report concludes that platform growth strategies must be tailored to target specific user profiles: P6 for volume, P2 for user growth. It posits that Polymarket's future may lie at the intersection of crypto and AI, potentially becoming a mass-market platform for autonomous trading agents.

The Midfield Battle of Perp DEX: The Declining, The Self-Rescuers, and The Latecomers

The article "Perp DEX Midfield Battle: The Declining, The Self-Rescuers, and The Newcomers" discusses the shifting landscape of decentralized perpetual exchanges (Perp DEX). Hyperliquid saw a weekly trading volume of approximately $15 billion, driven largely by commodity contracts like crude oil, gold, and silver amid geopolitical tensions and market volatility. Meanwhile, GMX Labs is hiring a CEO, moving away from its founder-driven model, and dYdX's market share dropped from 73% in early 2023 to single digits by late 2024. The decline of GMX and dYdX is attributed to several factors: reliance on token incentives that inflated trading volumes artificially, architectural limitations (e.g., GMX's liquidity pool model capping open interest, dYdX's costly migration to Cosmos), and misjudging key competitive factors like performance and market maker density. Hyperliquid, in contrast, grew slowly without VC backing or token incentives. It built its own L1 chain with a fully on-chain order book, focusing on transparency to attract market makers. It strategically expanded into traditional assets only after establishing a robust ecosystem, enabling it to capture demand during events like the Iran crisis. It now leads with ~54% of open interest among top Perp DEXs, ahead of Aster (~15%). The article concludes that the first generation of Perp DEXs is transitioning to professional management, while new opportunities lie in replacing traditional financial infrastructure, as Hyperliquid demonstrates by handling real-world demand.

"Crypto Czar" Steps Down: 130-Day Political Performance Concludes, How Much of Trump's Crypto Promises Remain?

"Crypto Czar" David Sacks has stepped down after reaching the 130-day term limit for his special government role. Appointed by former President Trump in December 2024 to lead AI and crypto initiatives, Sacks was tasked with creating a clear regulatory framework for the cryptocurrency industry in the U.S. During his tenure, Sacks achieved several symbolic victories, including organizing the first-ever White House Crypto Summit, establishing a strategic Bitcoin reserve (using seized assets rather than new purchases), and facilitating the passage of the GENIUS Act, which provides a federal framework for stablecoins. However, the article argues that these accomplishments were largely performative. The crypto summit was criticized as a publicity event with little substantive policy discussion. The Bitcoin reserve did not involve new government purchases, failing to inject liquidity or strong endorsement into the market. Moreover, the more impactful CLARITY Act—intended to provide regulatory clarity for crypto markets—remains stalled in Congress, with recent drafts favoring traditional banks over crypto interests, causing concern in the industry. Sacks will continue as co-chair of the Presidential Council on Technology, focusing on AI policy, signaling a shift away from crypto advocacy. The piece concludes that Trump’s pro-crypto promises have resulted in political theater rather than meaningful, lasting regulatory progress.

RWA Weekly: Compromise on Crypto Market Structure Bill Sparks Industry Divisions; Three Major Traditional Exchanges Develop Tokenization Products

RWA Weekly Digest: March 21–27, 2026 The RWA sector saw steady growth, with total on-chain market cap reaching $26.6 billion (+4.73% MoM) and holder count rising to 694k (+6.07% MoM). Stablecoin market cap remained stable at ~$3 trillion, though transaction volume and active addresses declined, indicating more holding than trading activity. Key regulatory developments included a U.S. crypto market structure bill compromise on stablecoin yield provisions, causing division within the industry, and Delaware’s proposed legislation to bring stablecoins under banking supervision. Major exchanges and institutions advanced tokenization: NYSE partnered with Securitize; Nasdaq collaborated with Talos; CME and Bank of Montreal launched tokenized cash settlement services. Franklin Templeton and Ondo introduced a 24/7 tradable tokenized ETF, while Invesco acquired Superstate’s $900M on-chain treasury fund. Ecosystem developments included Circle integrating USDC into Africa’s Sasai network, USDT₀ expanding to Tempo blockchain, and Ripple testing RLUSD for automated cross-border trade settlements in Singapore. Financings included XFX raising $17M for fiat-stablecoin FX infrastructure and Payy securing $6M for private stablecoin payments. Reports highlighted concerns from the FSB on dollar stablecoin risks in emerging markets and Electric Capital’s analysis showing only 34 RWA assets exceed $50M in on-chain size, with AI infrastructure spending poised to drive future growth.

From Speculation to Utility: Why AI and Stablecoins Remain Unfazed by the Bear Market?

Despite the overall downturn in the cryptocurrency market in 2026, the AI and stablecoin sectors have outperformed, showing resilience and continued adoption. While Bitcoin price dropped by 18.5% and the total crypto market cap fell to $2.42 trillion, these two areas recorded significant growth in usage and market activity. Key data highlights include: - The AI token sector declined by only 14% in Q1 2026, the smallest drop among major categories. - Stablecoin total market cap reached a record $3.2 trillion, with monthly trading volume hitting $1.8 trillion in February 2026, also a historic high. USDC supply grew by 220% since November 2023, reaching $78 billion, while ChatGPT’s weekly active users increased tenfold to 900 million during the same period. Tether’s USDT remains the leading stablecoin with a $184 billion market cap. The convergence of AI and stablecoins is driven by structural trends: AI requires fast, low-cost payment systems, and stablecoins serve as ideal “internet money.” Both sectors benefit from real-world utility beyond speculation—AI enhances productivity and security, while stablecoins provide efficient global dollar distribution and settlement infrastructure. This shift reflects a broader market transition from speculation to practical, infrastructure-focused applications, positioning AI and stablecoins for sustained growth.
