Positron, an AI chip startup focused on designing hardware that helps models run more quickly, said it has raised $875 million at a valuation of $5 billion, marking a significant increase in the company's worth over the last six months.

The debate over AI regulation is expected to heat up ahead of the midterm elections in November, according to one brokerage. "Data centers are expected to remain prominent in campaign discourse over the next two months, supported by significant technology-sector political spending," said strategists at brokerage Jefferies, in a note to clients. "After the elections, however, data-center opposition may lose force as the primary line of attack. Attention is expected to shift toward AI safety and AGI-related risks in 2027, while public resistance to individual projects remains but becomes more manageable."
