Energy companies raised $12.6 billion through IPOs in the first half of 2024, the highest half-year total since 1999, as investors seek exposure to the power demands of AI data centers. This surpasses the full-year 2025 total of $4.3 billion and represents a marked acceleration in energy sector fundraising. The capital influx reflects growing recognition that electricity supply has become a critical constraint limiting expansion of AI infrastructure.
Sakana AI
Sakana AI, a Tokyo-based AI lab, is hiring across multiple roles including researchers, engineers, product managers, and business development specialists to work on AI products like Sakana Chat, Marlin, and Fugu, as well as autonomous agent and multi-agent LLM systems. The company is recruiting for infrastructure, applied research, enterprise solutions, product, sales, marketing, and operations positions to scale its business globally. Open positions span full-stack ML infrastructure, security controls for AI applications, product vision leadership, and go-to-market strategy development.

Menlo Ventures led a $1.5 billion Series D funding round for Fireworks, a platform for deploying and optimizing specialized AI models in production. Fireworks has grown daily token volume to 43 trillion tokens (nearly tripled since late 2024) and reached $1 billion annualized revenue, serving customers like Cursor, Vercel, and Factory. The funding reflects growing demand for inference infrastructure as companies increasingly deploy custom and open-source models alongside frontier models to balance cost, speed, and performance.

Meta launched Spark 1.1, a proprietary frontier model with pricing at $1.25 per million input tokens, marking a shift from the company's three-year commitment to open-weights AI. CEO Mark Zuckerberg announced the model publicly after a three-year absence from social media, while Meta simultaneously introduced the Spark Image model and began building Meta Compute, a cloud service to sell surplus AI infrastructure. Meta is now assembling a complete vertical stack including custom chips, datacenters, cloud services, and models, positioning itself to compete directly with frontier AI labs, though structural advantages favor the company in end-user applications rather than model development.

Meta is developing four successive generations of its custom MTIA AI chips scheduled for deployment between 2026 and 2027, expanding capabilities from ranking and recommendation tasks to generative AI workloads. From MTIA 300 to MTIA 500, high-bandwidth memory increases 4.5x and compute performance increases 25x within two years. The modular chiplet design allows Meta to ship new generations every six months while using the same physical infrastructure, reducing deployment friction compared to traditional chip development cycles.
