Markets Today: AI Stocks Sink on OpenAI Revenue Doubts as Oil Spikes — Bitcoin Tests $81K (October 8, 2026)

By ToolPilot Editors · Updated October 8, 2026

S&P 500 and Nasdaq fell again as an FT report on OpenAI's revenue rattled AI stocks and oil spiked toward $105. Bitcoin broke below $82K. Movers and what's next.

Updated October 8, 2026 — stock prices as of the US market close (4 p.m. ET). Crypto trades around the clock, so treat these as a snapshot as of Thursday afternoon ET, not a live quote. Not financial advice.

Thursday was a risk-off day with an AI-flavored twist. Stocks fell for a second straight session as Brent crude ripped toward $105 a barrel and the 10-year Treasury yield probed 24-year highs — and tech took the worst of it after the Financial Times reported OpenAI's annualized revenue is $20 billion lower than previously signaled, shaking faith in the AI spending boom (Investopedia; Reuters). Bitcoin broke below $82,000 support to its lowest since September 21 as $485 million fled US spot Bitcoin ETFs in a single day (TradingNews).

Crypto snapshot

Bitcoin's third test of the $82,000–$83,000 zone failed during New York hours. The coin is down about 7% from $86,600 a week ago after three rejections near $87,000 since September 23. The macro tape did the damage: Brent at $105 and a 10-year Treasury at 5.35% are repricing every long-duration asset at once. US spot ETFs saw $484.9 million of net outflows on Wednesday — the largest daily exit since June — with BlackRock's IBIT alone shedding $207.7 million, while roughly $547 million in leveraged crypto positions were liquidated (TradingNews; CoinStats). One offsetting bid: Robinhood added $25 million of Bitcoin to its balance sheet on Tuesday (CoinStats). On social media the mood was gallows humor — CoinGecko's viral post read "NOW: Bitcoin falls below $81,000" over a sea-of-red treemap, with traders split between calling it a crash and shrugging it off as normal volatility.

Stock market snapshot

Both the S&P 500 and Nasdaq fell for a second straight session after Tuesday's record closes, with the Nasdaq's drop its biggest in nearly two months (Wall Street Journal; Reuters). Small caps fared worse: the Russell 2000 slipped about 1% on the day, down 2.3% across two sessions — the corner of the market most exposed to floating-rate debt (TradingNews).

Today's winners and losers

Winners

• Chipotle (+6–7%) — surged on a report that Starbucks had explored a takeover of the burrito chain (Reuters).
• Palantir (+5%) — topped S&P 500 gainers on a broadly red day (Stocktwits).
• Energy stocks (+3% as a sector) — the day's clear winning group on the crude spike (Reuters).
• Meteora (MET, +51%) — the standout crypto gainer on $222 million in 24-hour volume; Quantus (+46%) and Pearl (+19%) also jumped (CoinStats).

Losers

• Intel and Oracle (-5.5% each) — led the AI-profit-doubt selloff (Reuters).
• Nvidia (-3%) — the worst Dow component as chip stocks fell 4% broadly; the SOXX semiconductor ETF dropped 3.5% (Investopedia).
• Memory names — Samsung's preliminary Q3 results missed estimates, dragging the Roundhill Memory ETF (DRAM) down 5% (Investopedia).
• Solana (-6.4%), XRP (-5.6%) — large-cap crypto fell harder than Bitcoin on the day (CoinStats).

What's driving the moves

• The OpenAI revenue gap. The FT, citing investor documents, reported OpenAI's annualized revenue is $20 billion below the $70 billion previously signaled — largely sales flowing through AWS, Google and Microsoft Azure. It landed as a reminder that the winners of the AI race increasingly look like whoever owns the distribution toll booth (Investopedia).
• Oil's surge. Brent jumped about 5% to ~$105 and WTI to ~$93 after Iran struck a vessel near Qatar, threatening Strait of Hormuz tanker traffic, while Hurricane Isaias menaced Gulf output. Crude rallied even after Trump said the US will not attack Iran before November's midterms — oil rose 4% "largely ignoring" the pledge, per Reuters (Wall Street Journal; Reuters).
• Yields at 24-year highs. The 10-year touched 5.35% — highest since 2002 — before easing to 5.23% after a strong 30-year auction. September Fed minutes showed most officials still expect another hike by year-end; Governor Waller said more hikes are needed with "flexibility" on pace. CME FedWatch puts a December hike at 66% odds (Wall Street Journal; Stocktwits).
• Earnings cross-currents. PepsiCo topped expectations but cut its profit forecast; Applied Digital posted a revenue jump some read as a bullish AI-demand signal; crypto's own damage came from the $485M ETF outflow day and $547M in liquidations, partly offset by friendlier policy news as FinCEN withdrew two crypto reporting proposals (Investopedia; CoinJuice).

What investors are watching next

• Q3 earnings. FactSet data cited by CNBC puts expected S&P 500 blended earnings growth at about 30%. "If earnings remain strong… that is going to sustain this rally — despite the fact that rates are higher," Payne Capital Management's Courtney Garcia told CNBC (Stocktwits).
• The December Fed meeting. With 66% hike odds priced, every inflation print moves the needle — and some desks warn AI-driven demand could itself push inflation up.
• Oil's twin risks — the Strait of Hormuz situation and Hurricane Isaias's path will decide whether $105 Brent is a spike or a floor.
• Bitcoin's $80,000 line. TradingNews notes $80,000 sits just 1.4% below current prices — "a close under it opens $79,299, while bulls need $87,500 to target $90,000." ETF flow direction is the near-term tell (TradingNews). UBS, meanwhile, advised investors to remain invested despite the volatility, per CNBC (Stocktwits).

The bottom line: Thursday was the market asking what the AI boom is actually worth. A $20 billion hole in OpenAI's reported run-rate, $105 oil, and 5.35% ten-year yields are each survivable alone — together, they forced a rethink of record-high multiples. Energy was the only hiding place in equities; in crypto, there wasn't one. With Q3 earnings about to test whether profits can carry these valuations, the next two weeks matter more than the last two days. Not financial advice.
