Bitcoin could hit $135K by year-end, Citi says

Citi analysts project Bitcoin could reach $135,000 by year-end in a base case, or $199,000 in a bullish scenario, driven primarily by increasing spot ETF demand and user adoption, despite macroeconomic headwinds. ETF inflows are estimated to contribute $63,000 to the price outlook and account for over 40% of recent price variation. This optimistic forecast is reinforced by growing institutional 'buy and hold' treasury strategies from public companies like MicroStrategy and Blockmate Ventures, alongside expanding operations of major Bitcoin miners such as Marathon and HIVE, collectively indicating strong market momentum into the second half of 2025.

Analysis

Citigroup analysts have established a strongly bullish outlook for Bitcoin, projecting a base-case price of $135,000 and a bullish case of $199,000 by year-end 2025, against a current price of approximately $115,000. This forecast is predominantly driven by institutional demand via spot ETFs, with Citi estimating that $15 billion in inflows could add roughly $63,000 to the price, a factor now accounting for over 40% of recent price variations. This structural demand is complemented by a projected 20% increase in user adoption, which independently supports a $75,000 price level. These tailwinds are significant enough to outweigh minor macroeconomic headwinds, which are estimated to detract only $3,200 from the price. The thesis is further substantiated by tangible corporate and operational trends. Publicly traded companies including MicroStrategy (MSTR), Galaxy Digital (GLXY), and newcomer Blockmate Ventures (MATE) are actively pursuing 'buy-and-hold' or 'mine-and-hold' treasury strategies, creating a persistent source of demand. Concurrently, major mining operations are aggressively expanding capacity, signaling confidence in future profitability. HIVE Digital (HIVE) is targeting 25 EH/s by year-end, Marathon Digital (MARA) aims for 75 EH/s by the end of 2025, and Riot Platforms (RIOT) is building a 1-gigawatt facility, all of which enhance network security and reflect deep capital investment in the asset's infrastructure.

Key Decisions for Investors

• Given the heavily skewed upside in Citi's forecast, driven by quantifiable ETF inflows, investors may consider the current environment favorable for maintaining or initiating long positions in Bitcoin.
• For those seeking leveraged exposure to the Bitcoin price, the aggressive expansion and strong operational updates from miners like HIVE, RIOT, and MATE suggest these equities could offer amplified returns, though they carry higher operational risk.
• Investors should closely monitor spot Bitcoin ETF flow data, as the analysis identifies this as the single most significant price driver; sustained inflows would validate the bullish thesis, while a reversal would signal a potential shift in momentum.
• The emerging trend of corporate treasury adoption by firms like MSTR and MATE should be watched as a key indicator of deepening institutional acceptance, with new announcements likely serving as further positive catalysts for the asset class.
