Sept 29 (Reuters) - The benchmark S&P 500 was flat on Tuesday, as rising government bond yields hurt risk sentiment and offset gains in AI-related stocks driven by optimism about Anthropic's plan to go public.
The yield on the benchmark 10-year Treasury bond US10YT=RR climbed to 5.278% — near its highest level since 2007 — strengthening expectations of a tighter monetary policy.
Oil prices retreated, but concerns that energy-driven inflation would force central banks to keep interest rates elevated for longer hit risk assets.
US President Donald Trump earlier said he has offered Iran nothing to end the war, rejecting media reports that he was willing to offer some relief from sanctions.

Six of the 11 S&P 500 sectors lost ground — with healthcare .SPXHC the biggest drag, down 0.8%.
Chipmakers helped offset declines as they recovered some ground after the previous session's sharp fall. The broader Philadelphia chips index .SOX climbed 2.1%.
Megacap and growth stocks were mixed. Meta Platforms META.O and Nvidia NVDA.O advanced, while Microsoft MSFT.O and Apple AAPL.O fell around 1% each.
Tech stocks were in focus as Anthropic's IPO prospectus showed how the AI lab has grown sharply in the last year but also posted wider losses. The company is targeting a $2 trillion-plus valuation, possibly setting a benchmark for how Wall Street measures AI leaders.
"The market is in somewhat of a show-me phase," said Newton Jones of Zizmer-Jones Private Wealth Management Group at Steward Partners. "Earnings growth has been phenomenal, but expectations are extremely high and a lot of the good news is already priced in."
The AI theme, which has powered most of the bull run since October 2022, remains crucial. Remarks from OpenAI CEO Sam Altman during the company's DevDay event later in the day would be on investors' radar.
On the data front, job openings fell to 7.079 million in August, a US Labor Department report showed. Meanwhile, the September Consumer Confidence Index was at 81.9, missing analysts' estimates of 89.2.

Oil tanker freight reaches a sixty-year high: shipping oil from the US to China is more expensive than launching a rocket!
The freight for a single barrel of crude oil has soared to $41, approaching half the oil price, and for a single trip, the freight was once enough to buy an oil tanker. The Middle East crisis has led to a structural shortage of shipping capacity in the Strait of Hormuz, coupled with ship-to-ship transfers extending turnaround times. VLCC freight rates have skyrocketed from an annual average of $9.2 million to $77 million—an increase of more than eight times. Refiners’ profits are being rapidly eroded, the average price of second-hand oil tankers has reached a historic high, and, unusually, surpassed the price of new vessels.

Following the Drop but Not the Rise! Silver Trapped in Difficulties
The logic of AI and solar energy demand continues to play out, yet prices are falling against the trend—macroeconomic forces such as a strengthening US dollar and rising real interest rates have completely suppressed fundamentals. Speculative funds offloaded $1.6 billion in a single week, marking a yearly peak, while CTA net short positions reversed by $2.6 billion to the highest level this year. However, Goldman Sachs analysts believe that the extreme short positioning itself is building reversal momentum, highlighting an asymmetry; once macro headwinds subside, a retaliatory rebound could be easily triggered. After a similar shakeout last time, silver surged 15% in six weeks.
