Samsung and six affiliates commit $1 billion to KKR's Helix as Fed's Cook links AI spending to inflation

Megaport signed $687 million of AI infrastructure deals and raised its forecast, and AMD agreed to acquire Fei-Fei Li's World Labs. Samsung's 2nm yield was reported approaching 60% as China weighed allowing Nvidia chip purchases. Local resistance hardened, from a Tasmanian council move against a Firmus site to residents calling $10,000 checks a bribe.

Key notes

1bn USD
Samsung group commitment to Helix

Samsung is putting money into AI infrastructure outside its own fabs. Samsung Electronics and affiliates committed $1 billion to Helix, an AI infrastructure firm backed by KKR and Nvidia, according to WSJ, Bloomberg and The Korea Herald.

518bn USD
Anthropic AI infrastructure spending plan

Anthropic's infrastructure ambitions set a new reference point for model-developer spending. CoinDesk reported Anthropic plans to spend $518 billion on AI infrastructure, while pre-IPO perpetual contracts barely moved.

687mn USD
Megaport AI infrastructure deals

Network provider Megaport booked a large block of AI work. Reuters reported the Australian company signed $687 million of AI infrastructure deals and lifted its annual forecast; other reports said it raised its 2027 earnings forecast.

60%
Samsung 2nm yield, reported

Samsung is closing in on foundry competitiveness at the leading edge. Its 2-nanometer yield was reported approaching 60%, positioning it against TSMC for orders from large technology customers.

10.3tn USD
US AI data center spending forecast through 2032

Macro concerns about the build-out gained airtime. IndexBox put US AI data center spending at $10.3 trillion through 2032 and said it could overheat the economy, while Fed Governor Cook said AI infrastructure spending is pushing up inflation first.

Cooling and power supply deals

Suppliers moved on cooling and power for AI halls. LG Electronics expanded AI data center cooling ties with Microsoft and SK Enmove, Navitas agreed to acquire Claros for data centre power delivery, and Bloom Energy was reported soaring on AI data center orders.

Agentic RL and cluster communication papers report multi-fold speedups in training and serving

VarioPath (USTC, Alibaba) cut AlltoAllv latency 5.9× for MoE inference on PCIe clusters of up to 256 GPUs, KV-streams (Meta AI, UC Berkeley) reported a 3.8× wall-clock training speedup, and Alibaba's PEARL lifted rollout throughput 2.5×; Nereus reported 2.1× on 8B PPO post-training. None of the eight papers released code or weights. Cambridge and Edinburgh's AgentPerfBench argues existing inference benchmarks mismatch real agentic workloads.
