PSX & KMI Launch Second Open Season for Western Gateway Pipeline

Phillips 66 and Kinder Morgan launched a second open season (Jan. 16–Mar. 31, 2026) for the proposed Western Gateway Pipeline after strong customer demand to allocate remaining capacity; the project would add a new Borger, TX–Phoenix connecting pipeline, leverage SFPP flow reversal (Watson–Colton) and a reversed PSX Gold line to enable refined-fuel flows into Phoenix, California and connectivity to Las Vegas via CALNEV. The proposal emphasizes fee-based, midstream cash flows that should boost PSX and KMI liquidity profiles and investor appeal; Zacks ranks both firms #3, and peers cited include EPD (Zacks #3) and WMB (Zacks #4), the latter having filed an FERC application to expand Pine Prairie storage. Investors should view the announcement as supportive for midstream utilization and near‑term cash‑flow upside, while project timing, regulatory approvals and execution risk remain key variables.

Analysis

Market structure: The Western Gateway open season (Jan 16–Mar 31, 2026) re-allocates remaining capacity and is a clear win for fee‑based midstream (KMI, PSX) — expect incremental EBITDA contribution that is high-margin and less correlated with crude prices. Direct losers: West Coast rack owners and local refiners could see regional gasoline/jet crack spreads compress as incremental supply reaches California; estimate a potential 2–4 USD/bbl downward pressure on regional crack spreads if flows rise materially. Cross-asset: stronger midstream cashflows should narrow KMI/PSX corporate bond spreads by 25–75bp on confirmation and compress equity volatility; RBOB futures may fall modestly near-term.

Risk assessment: Tail risks include FERC denial, environmental injunctions, or failed SFPP flow reversal; assign combined low‑to‑medium probability (10–25%) but high impact (project delay +$0.5–$1.0bn capex overrun). Time horizons: immediate (days to Mar 31) — allocation signals; short (3–9 months) — binding contracts/FERC approvals; long (12–36 months) — construction, flow reversals and realized margins. Hidden dependency: interconnect capacity at Borger, CARB/regional fuel spec compliance, and storage constraints that could mute takeaways.

Trade implications: Primary tactical tilt is long KMI/PSX exposure funded by modest profit-taking elsewhere in energy infrastructure. Use 6–12 month option structures to asymmetrically capture upside on confirmed allocations (e.g., buy-call spreads or sell 5–10% OTM puts). Relative trades: favor liquids‑focused midstream (KMI) vs gas‑centric WMB; monitor open season subscription levels (>70% = buy signal).

Contrarian angles: Consensus understates the timeline/regulatory friction — market may be underpricing 6–12 month execution risk and overpricing immediate EBITDA impact. Also, added westward flows could paradoxically compress refiners’ margins (hurting PSX refining unit) even as PSX midstream benefits; net impact on PSX depends on scale of fee revenue vs refining margin loss, which history shows can swing earnings by ±5–10% over 12–24 months.

Key Decisions for Investors

• Establish a 2–3% long position in Kinder Morgan (KMI) equity exposure via a 12‑month call spread (buy near‑ATM, sell ~+30% OTM) sized to target 12–20% IRR; add +1% if open season subscriptions >70% when it closes Mar 31, 2026; stop-loss: close if allocation <50% or announced FERC denial.
• Establish a 1.5–2.5% tactical long in Phillips 66 (PSX) using either shares with covered calls (6–12 month) or a call spread (buy ATM, sell +25% OTM); monitor PSX refining crack spread — trim positions if regional crack spreads compress >$3–4/bbl QoQ indicating net negative to refining unit.
• Implement a relative value pair: long KMI / short WMB in a 1:1 dollar-neutral size (target 1–2% net portfolio exposure) to capture liquids midstream upside vs gas-focused downside; unwind if KMI underperforms WMB by >10% over 60 trading days or if WMB announces materially accretive projects.
• Sell 5–10% OTM cash‑secured puts on KMI or PSX with 3–6 month expiries to collect yield if bullish but prefer net allocation cap of 1–2% per name; only exercise if assigned shares below your stop thresholds and conditional on open season outcome (>60% subscription).
