[0:00] Speaker 1: News when you want it with Bloomberg News Now. I'm
[0:04] Speaker 1: Ed Kalangi. Leaders of the world's biggest artificial intelligence platforms
[0:08] Speaker 1: say it's time to slow the development pace of their
[0:11] Speaker 1: most advanced and most lucrative models, citing escalating risks of
[0:15] Speaker 1: the technology. Anthropic CEO Dario Amadei issued a lengthy blog
[0:19] Speaker 1: post Saturday saying his company would implement new safety steps,
[0:23] Speaker 1: such as third-party evaluators, while calling on the industry to
[0:27] Speaker 1: support a broader downshift. OpenAI chief Sam Altman quickly pledged
[0:31] Speaker 1: to adopt Amadei's suggestion of independent evaluators with employee-like access,
[0:36] Speaker 1: while Elon Musk, who runs XAI, wrote, Dario is right.
[0:40] Speaker 1: The anxiety about severe AI risks has begun to enter
[0:43] Speaker 1: the mainstream, driven in part by this week's high-profile resignation
[0:47] Speaker 1: of an anthropic researcher over existential fears that his company
[0:50] Speaker 1: was acting irresponsibly. This came on a day when OpenAI
[0:54] Speaker 1: said it will not go public in 2026. Sam Altman
[0:58] Speaker 1: told Fortune magazine in an interview citing need for safety-related work.
[1:03] Speaker 1: Altman said an initial public offering would be ill-timed this
[1:06] Speaker 1: year and won't take place until 2027 due to the
[1:09] Speaker 1: safety concerns around artificial intelligence. The company confidentially filed for
[1:13] Speaker 1: an IPO in June, though it has said the timing
[1:16] Speaker 1: for the listing remained undecided. At the U.S. Open, Elena
[1:21] Speaker 1: Rybakina defeated Arina Savalenka 6-4, 5-7, 6-2 to win the
[1:25] Speaker 1: Women's Championship. It's her third Grand Slam title and second
[1:28] Speaker 1: of 2026. Tesla Saturday said it will finally unveil the
[1:32] Speaker 1: second-generation Roadster on October 1st. In a post on X,
[1:36] Speaker 1: the electric vehicle company wrote, go for launch, with a
[1:39] Speaker 1: graphic showing a 10.01 date. So the expectation is the
[1:44] Speaker 1: new Roadster will be unveiled on October 1st. The graphic
[1:47] Speaker 1: also seems to hint at the promised cold gas thrusters
[1:50] Speaker 1: developed by Tesla CEO Elon Musk's other big company, SpaceX.
[1:55] Speaker 1: Speaking of SpaceX, it is set to get a larger
[1:58] Speaker 1: weighting in the Nasdaq 100 later this month, a change
[2:01] Speaker 1: that could trigger billions of dollars of buying by passive
[2:04] Speaker 1: funds tied to the benchmark. Its weighting is expected to
[2:07] Speaker 1: rise to about 2.82 percent from roughly 1.28 percent based
[2:12] Speaker 1: on pro forma data from Nasdaq's global index watch circulated
[2:16] Speaker 1: late Friday. The final weighting will be determined later this month.
[2:19] Speaker 1: Wall Street expects the change to result in billions of
[2:22] Speaker 1: new buying by index funds. and exchange-traded funds to track
[2:26] Speaker 1: the benchmark. President Trump has expressed optimism about resolving a
[2:30] Speaker 1: trade fight with Canada. Bloomberg's Monica Ricks reports.
[2:33] Speaker 2: President Trump says a trade deal with Canada could come
[2:36] Speaker 2: fairly soon, and he downplayed the prospect of quitting a
[2:39] Speaker 2: continental trade pact with Canada and Mexico.
[2:42] Speaker 1: We're going to have a great relationship with Mexico. We
[2:45] Speaker 1: actually have a good one with Canada, but the United
[2:47] Speaker 1: States has been.
[2:48] Speaker 3: Ripped off for a 50 years by Canada.
[2:51] Speaker 1: They don't need their product.
[2:52] Speaker 2: And they need our product. The president talking to reporters
[2:55] Speaker 2: today in Ireland. He didn't say whether talks had resumed,
[2:58] Speaker 2: but warned Canada has to treat U.S. farmers better and
[3:01] Speaker 2: stop charging them tariffs if they want to reach a deal.
[3:04] Speaker 2: The clashes are now threatening to rupture cross-border supply chains.
[3:08] Speaker 2: Monica Ricks, Bloomberg Radio.
[3:10] Speaker 1: President Trump said he would like to see Ireland unified,
[3:13] Speaker 1: a remark that puts him at odds with U.K. Prime
[3:15] Speaker 1: Minister Andy Burnham, who recently said the issue was off
[3:18] Speaker 1: the table. He made the remarks during a meeting with
[3:20] Speaker 1: Irish Prime Minister Michael Martin in Dublin, where he visited
[3:24] Speaker 1: before a trip to his golf course in the west
[3:26] Speaker 1: of Ireland. The issue of a border poll, as the
[3:29] Speaker 1: vote on unification is known, is contentious in both the
[3:32] Speaker 1: UK and Ireland, which act as co-guarantors of the 1990s
[3:36] Speaker 1: peace accord that largely ended sectarian violence between British unionists
[3:41] Speaker 1: and Irish nationalists in Northern Ireland. The pressure is on
[3:45] Speaker 1: for Fed Chair Kevin Warsh to raise interest rates next week,
[3:48] Speaker 1: following the latest CPI report, which showed U.S. consumer prices
[3:52] Speaker 1: pushed higher last month. Tom Orlick is chief economist for
[3:56] Speaker 1: Bloomberg Economics.
[3:57] Speaker 3: There's been a structural shift from a world where there's
[4:01] Speaker 3: too much saving, a savings glut, and not enough investment
[4:06] Speaker 3: opportunities for a world in which too much saving means
[4:10] Speaker 3: interest rates are falling, to a world where there's a
[4:14] Speaker 3: dearth of saving, enormous investment opportunities, and that means structural
[4:20] Speaker 3: pressure for interest rates, bond yields to stay high.
[4:24] Speaker 1: Traders are putting the odds of a rate hike at
[4:26] Speaker 1: next week's Fed meeting at about 90 percent, up from
[4:29] Speaker 1: about 70 percent on Thursday. The House is expected to
[4:32] Speaker 1: take up a bill this week aimed at keeping data
[4:35] Speaker 1: center costs out of Americans' power bills. Bloomberg's Nathan Hager
[4:39] Speaker 1: reports from Washington.
[4:40] Speaker 4: The Ratepayer Protection Act sailed through the House Energy and
[4:43] Speaker 4: Commerce Committee in July, but it's been unclear if the
[4:45] Speaker 4: full House would take it up until now. Republicans have
[4:48] Speaker 4: been making the case for data centers' benefits while pushing
[4:51] Speaker 4: for companies to cover their costs. House aides tell Bloomberg
[4:54] Speaker 4: government lawmakers will consider the bill on suspension, meaning it
[4:58] Speaker 4: will need a two-thirds vote to pass. This will be
[5:00] Speaker 4: one of the last votes in the House before lawmakers
[5:03] Speaker 4: break for midterm elections. In Washington, I'm Nathan Hager, Bloomberg Radio.
[5:08] Speaker 1: That's news when you want it with Bloomberg News Now.
[5:11] Speaker 1: I'm Ed Kalecki. This is Bloomberg.
