On Sep 10, 2026 Amazon Ads announced a pilot letting select US brands buy ads in ChatGPT, with campaigns set up and managed by Amazon while OpenAI's ads system controls delivery; units appear as text or images beneath ChatGPT responses. It is a vote of confidence from the largest online retailer in OpenAI's ad business, which hit a $1B annualized run rate on Aug 31, roughly eight months after OpenAI began selling US sponsored placements. It adds a major demand channel to OpenAI's nascent advertising revenue line.

On 2026-09-10 Motive Technologies filed a Form RW with the SEC withdrawing the S-1 it had filed in December 2025 for a NYSE listing under ticker MTVE, which Renaissance Capital estimated would have raised about $600 million with J.P. Morgan, Citigroup, Barclays and Jefferies as lead managers. CEO Shoaib Makani said the General Catalyst financing left the company 'very well capitalized' and it remains positioned to list in future. The withdrawal removes the near-term public exit and makes secondaries the main liquidity path.

Mistral closed a €3 billion Series D on September 8, 2026, at a post-money valuation above €21 billion (roughly $24 billion). Mistral calls it the largest equity fundraising round ever completed by a European tech company. • Leads: Samsung Electronics, with the EQT-managed Scaleup Europe Fund and existing investor PSG Equity as co-leads. Advent International also came in as a new investor. • Jump: roughly double the €11.7 billion post-money from the September 2025 Series C, which ASML led with €1.3 billion almost exactly a year earlier. • Use of funds: compute capacity and infrastructure, model training, commercial growth, and international expansion. Mensch told CNBC the company wants to rely much more on compute it owns rather than renting. • Politics: Macron posted that the round reflects a France–South Korea aim of building a "third way" in AI. Samsung's arrival on the cap table reportedly had the blessing of French authorities.

At a 9 September 2026 fireside chat with Boston Mayor Michelle Wu at the Harvard Kennedy School, Whoop CEO Will Ahmed said the company will hire more than 600 people in 2026, roughly an 80% expansion from the 750-800 employees it started the year with (MassLive); Inc. put the increase in hiring at 74% versus 2025, with a deliberate push for entry-level and college-graduate roles. It is a rare disclosed scale metric for the $10.1B-valued wearables maker and runs counter to AI-driven layoffs elsewhere in tech.

The Boring Company closed a $3 billion Series D on September 9, 2026, at a $23 billion valuation — about four times the $5.7 billion it was worth after the 2022 Series C. • Lead: the United Arab Emirates and affiliated investment entities. Participants include Sequoia, Andreessen Horowitz, Temasek, Valor Equity Partners, Vy Capital, Human Capital, Shamal Holding, and Baron Capital. • Use of funds: more than 150 km of tunnels across the UAE, building on the Dubai Loop project. The company puts the Dubai build at $545 million over roughly three years. • Unusual terms: per the WSJ, some investors were told they'd have to actively help the business — recruiting staff, or making introductions to government officials in cities where Boring wants to dig. The company reportedly kept the right to buy back shares from investors who don't deliver. • Vs. the earlier report: in late July the WSJ said Boring was in talks for $4 billion at $20 billion. It landed at $3 billion and $23 billion instead.
