AMD tops $1 trillion as bitcoin hits an 8-month high near $86,000

Chip stocks and bitcoin rallied together on Monday as markets leaned into Thursday's Trump-Xi summit in Washington and oil eased for a fourth straight session. As of the US close, the risk-on mood had lifted AI-linked equities and crypto alike, while European markets moved in the opposite direction.

Markets

The S&P 500 closed up 1.19% at 7,741.51, the Nasdaq Composite jumped 1.80% to 26,998.87, and the Dow added 0.47% to 51,927.75. The rally was led by chips: the Philadelphia Semiconductor Index (SOX) jumped more than 3%, AMD hit an all-time high above $610 a share to cross a $1 trillion market cap, and Arm Holdings and Intel both rose roughly 10%, with Broadcom and Nvidia also participating. The move was driven by AI-trade optimism ahead of Thursday's state dinner for Xi Jinping, which tech leaders including Jeff Bezos, Sundar Pichai, Sam Altman, Tim Cook, Elon Musk and Jensen Huang are expected to attend. It follows a rough prior week in which the Dow fell 1.7%.

European indices moved the other way. The FTSE 100 closed down 1.45% at 10,659, the DAX fell 1.63% to 25,296, the CAC 40 dropped 1.49% to 8,065, and the Stoxx 600 lost 1.2% to 635.3 — a sharp divergence from Wall Street's advance.

Commodities

Brent crude eased for a fourth straight session to roughly $101.60 a barrel, down about $2.72 from the prior close, as markets weighed a partial pullback in Middle East risk despite the weekend Houthi strike on Saudi Arabia that had kept oil-supply concerns elevated. Gold slipped about 0.3% to roughly $4,394 an ounce.

Crypto

As of 18:56 UTC, bitcoin traded at $86,054.70, up 6.0% from the 00:00 UTC open of $81,178.00 and touching an eight-month intraday high of $86,344.70. Ether rose 4.2% to $2,755.19, Solana gained 5.9% to $117.70, BNB rose 3.7% to $801.17, and XRP climbed 7.1% to $1.5109. Dogecoin was the standout mover, up 14.4% to $0.09986, a rally market commentary tied to the broader crypto risk-on phase, a technical breakout, and modest spot-ETF inflows rather than any DOGE-specific news. Most of bitcoin's gain landed between 08:00 and 10:00 UTC, well ahead of the US cash-equity open, in step with the broader risk rally rather than any crypto-specific catalyst.

On regulation, the US Senate narrowly blocked the CLARITY Act, and the CFTC opened an investigation into prediction-market platform Polymarket over allegations its CEO instructed staff to ignore internal compliance warnings during a $10 million stolen-card fraud attack on its US platform. Neither development dented crypto sentiment during the session.

What it means for crypto trading

This looks like a shared risk-on move, not a crypto-specific breakout: bitcoin's sharpest gains landed in the same window as the chip-stock rally and the broader rebound in risk appetite, not on any dedicated crypto news. The near-term risks that could reverse it are a disappointing outcome at Thursday's Trump-Xi summit or a fresh regulatory setback following the Senate's CLARITY Act block and the CFTC's Polymarket probe.
