Polymarket Seeks CFTC Approval to Bring Main Exchange to the US

April 29 — Despite Bitcoin’s recent gains, investors are ramping up bets on a price drop. Data from CEX.IO shows short sellers paid roughly 11% interest in April to keep their positions open, peaking at 19% at one point—its highest level since early 2023. Meanwhile, Bitcoin is in one of its biggest accumulation phases on record. The simultaneous jump in strong buying pressure and short selling activity signals the market could see sharp price swings, with one side at risk of being squeezed—including a potential short squeeze. Bitcoin was recently down 1.6% at $75,754.

April 29: NVIDIA officially launched Nemotron 3 Nano Omni, the latest addition to its Nemotron 3 series. The model integrates unified multimodal reasoning into a single, efficient open-source system. NVIDIA explains that agentic systems typically need a single perception-to-action loop spanning screens, documents, audio, video, and text—but they still rely on fragmented model chains: separate visual, audio, and text technology stacks. This boosts reasoning hops and orchestration complexity, driving up costs while eroding cross-modal contextual consistency. Nemotron 3 Nano Omni is designed to replace this fragmented visual-language-audio (VLA) stack, serving as a multimodal perception and context sub-agent within agentic systems. On accuracy, the model topped the document intelligence leaderboard and led in video and audio understanding rankings. Against the open industry benchmark MediaPerf for video understanding, it delivered the highest throughput across all tasks and the lowe

April 29 — LookOnChain data shows a BIT-affiliated whale (who previously netted over $59 million in profits) is ramping up their ETH long positions, now holding 63,000 ETH ($143.5 million) across three wallets.

On April 28, the Over Foundation announced it has shuttered all Over Protocol infrastructure and services—including OverWallet, OverNode, OverFlex, RPC nodes, a block explorer, and related APIs—with no plans to resume operations. Over Protocol is a Layer 1 mainnet; though designed to be decentralized, it will likely struggle to operate smoothly after the foundation cuts its services. Block production hinges on whether independent validators keep running the open-source client, a scenario the foundation says it cannot guarantee. Earlier this year, reports highlighted a wave of crypto project shutdowns, with Dmail, Tally, and Step Finance among the firms ceasing operations amid falling user activity, tighter funding access, and rising costs. Industry insiders note that relying on token fundraising has proven ineffective: crypto projects lack clear liquidation and restructuring frameworks, making it hard to coordinate creditor rights or revive operations during financial distress

April 28th — AI recruitment startup Dex has closed a $5.3 million seed round of funding, led by Notion Capital, with participation from a16z Speedrun, Concept Ventures, and angel investors including OpenAI alumni and industry peers. The round pushes the company’s total funding to $8.4 million. Founded by former Atomico advisor Paddy Lambros, Dex bills itself as an “AI talent agent” focused on high-end technical talent: AI researchers, software engineers, and the like. To date, over 15,000 engineers have registered on the platform, which serves 50+ tech firms including ElevenLabs and Synthesia. Dex’s tool interacts with job seekers via voice or text, builds candidate profiles using models from OpenAI, Anthropic, and other providers, and connects them directly to employers via a matching engine. Unlike traditional HR software vendors, Dex does not sell software to companies; instead, it charges a 20%–30% fee of a candidate’s salary upon successful placement. The startup reports
