Stock Market: Will S&P 500 Open Up or Down Today?

U.S. stock futures are trending higher early Wednesday as investors await the Federal Reserve’s highly anticipated interest rate decision and weigh cooling fears over an AI slowdown against the massive economic costs of the U.S.-Iran conflict.

The Polymarket (CRYPTO: POL) crowd is leaning bullish for the Sept. 16 trading session. The “S&P 500 (SPX) Up or Down on September 16?” contract currently reflects a 60% chance of a higher open.

Why That Number Matters

Traders are navigating a tense geopolitical environment and a pivotal central bank decision:

• Positive Index Futures: Equity futures are pointing to a green open across major benchmarks. Dow Jones futures rose 0.15%, S&P 500 futures advanced 0.16%, Nasdaq 100 futures gained 0.20%, and Russell 2000 futures ticked up 0.12%.
• Geopolitics & Energy: Oil prices eased slightly after recent surges, with Brent crude dipping 0.66% to $108.03 a barrel and WTI crude falling 1.08% to $104.69. However, the economic fallout of the U.S.-Iran war continues to dominate political discourse. Senator Elizabeth Warren (D-Mass.) highlighted a Congressional Budget Office estimate that the conflict has cost the Department of Defense nearly $40 billion and driven “nearly half” of U.S. inflation. Meanwhile, Senate Minority Leader Chuck Schumer (D-N.Y.) slammed President Donald Trump for blaming Ukraine for high diesel prices.
• Earnings & The Fed: All eyes are on the Federal Open Market Committee (FOMC), which is scheduled to announce its interest rate decision at 2:00 p.m. ET. After a run-up in energy prices and persistent inflation, the odds of a rate hike currently stand at 92.5%, according to the CME FedWatch tool. Wednesday’s earnings docket includes reports from Lennar Corporation (NYSE:LEN), LuxExperience B.V. (NYSE:LUXE), and Seabridge Gold Inc. (NYSE:SA).

The Bull Case and Market Outlook

Despite the looming threat of higher interest rates, underlying confidence in the technology sector remains robust. According to technology strategist Luke Lango, “AI doomerism fears cooled sharply” following the All-In Summit, where tech leaders pushed back against regulatory pacing and reaffirmed their capital expenditure plans.

Lango noted that Broadcom Inc.‘s (NASDAQ:AVGO) Hock Tan confirmed that 2027/2028 guidance remains entirely untouched by slowdown talk. He advised investors to “follow what they do, not what they say,” asserting that AI fundamentals aren’t changing even if market sentiment remains temporarily turbulent.

How the Previous Bet Played Out

The Sept. 15 Polymarket contract resolved “Down.” The contract recorded $53,343 in total trading volume.

On Tuesday, the SPDR S&P 500 ETF Trust (NYSE:SPY) and Invesco QQQ Trust ETF (NASDAQ:QQQ), which track the S&P 500 and Nasdaq-100, respectively, closed lower. SPY fell 0.46% to $757.39, while QQQ fell 0.65% to $704.54. Meanwhile, the Dow tracker, State Street SPDR Dow Jones Industrial Average ETF Trust (NYSE:DIA), also ended 0.62% lower at $521.23.
