NEW YORK, Jan 3, 2026, 06:58 ET — Market closed

Marathon Petroleum ended Friday up 1.6% at $165.14, setting a baseline ahead of weekend geopolitical shock.

U.S. President Donald Trump said Washington carried out a “large scale” strike in Venezuela and captured President Nicolas Maduro, injecting fresh uncertainty into oil markets before futures reopen.  Reuters

PDVSA’s key oil facilities were operating normally with no damage, sources said, potentially limiting immediate supply disruption.  Reuters

Marathon Petroleum (MPC) heads into the new week with investors bracing for volatility after the United States struck Venezuela overnight and President Donald Trump said Venezuelan leader Nicolas Maduro was captured and flown out of the country.  Reuters

Why it matters now: Marathon is a major U.S. refiner, and its shares tend to react less to crude prices alone than to refining margins — the gap between what refiners pay for crude and what they earn selling fuels. A geopolitical shock can move both sides of that equation quickly when markets reopen.  Reuters

Venezuela is a key heavy-crude producer and holds the world’s largest oil reserves, making any disruption — or a shift in U.S. sanctions policy — a direct watchpoint for Gulf Coast refiners. Early indications that Venezuelan oil operations were not hit could temper the initial supply-scare trade.  Reuters

Marathon shares last closed at $165.14 on Friday, up $2.53, or about 1.6%. Valero Energy gained about 1.5% and Phillips 66 rose about 1.2% in the same session.

Oil prices ended the week lower before the Venezuela strikes, with U.S. crude settling at $57.32 a barrel and Brent at $60.75, Reuters data showed. Those settlements are the reference point for the first reaction when oil futures reopen.  Reuters

On Saturday, Venezuelan state oil company PDVSA’s production and refining were normal and its most important facilities had suffered no damage from the U.S. attacks, two sources with knowledge of operations said. They added that the port of La Guaira sustained severe damage, but it is not used for oil operations.  Reuters

MST Marquee analyst Saul Kavonic said, “Oil prices were likely to jump on the near-term risk to supply.” He added that the move could turn bearish in the medium term if a new Venezuelan government leads to sanctions being lifted and fresh investment.  Reuters

That distinction matters for refiners. A “risk premium” is the extra price traders pay for crude because of geopolitical uncertainty; if it spikes while gasoline and diesel prices lag, refiners’ margins can tighten even if demand is steady.  Reuters

Traders often watch “crack spreads” — a benchmark margin that approximates the difference between crude costs and refined-product prices — for directional signals in refinery stocks. A sharp crude gap higher at Sunday’s reopen would be a near-term headwind for names like Marathon unless product prices rise in step.  Reuters

Competitive read-throughs will likely land on other complex refiners with significant U.S. Gulf Coast exposure, including Valero and Phillips 66, because those systems can be sensitive to shifts in heavy-crude availability and pricing.  Reuters

On a longer horizon, analyst targets still imply upside for Marathon. MarketBeat data shows an average 12-month price target of $203.07, roughly 23% above Friday’s close, though those forecasts typically assume normal market conditions rather than a sudden geopolitical shock.  MarketBeat

Before the next session, investors will focus on how crude and fuel futures reprice when markets reopen and on any fresh guidance from Washington after Trump said he would provide more details at an 11 a.m. press conference in Florida. Updates on Venezuelan security and PDVSA operations will be central to whether the move is treated as a supply disruption or a political transition trade.  Reuters

OPEC+ also meets on Sunday and is expected to maintain its oil output policy, sources told Reuters, another potential driver of the first post-strike oil move. Oil fell more than 18% in 2025 amid oversupply concerns, leaving markets sensitive to any new risk-premium shock.  Reuters

Macro data is also back in play next week. The U.S. jobs report is due Jan. 9 and the consumer price index follows on Jan. 13, events traders watch because they can shift interest-rate expectations, the dollar and, by extension, commodity prices.  Reuters

For Marathon specifically, near-term chart watchers will note Friday’s intraday low around $162.49 as a first support area and the session high near $165.36 as nearby resistance. The next fundamental checkpoint is quarterly results in early February; financial calendars list Feb. 3 as the expected report date, putting refining-margin commentary and crude-differential guidance in focus as the market absorbs Venezuela’s fallout.  Investing
